Abstract:
The Andean region of Northern South America is widely recognized as a hotspot with extreme levels of diversity, endemism, and threat. In a taxonomic study on jumping spiders from Colombia, nineteen new species of Amphidraus Simon, 1900 were found, all of which with small-scale endemic distributional patterns. Sixteen of these new species are described from the Andean region, eight of which being restricted to the Cundiboyacense high-Andean plateau (A. bochica sp. nov., A. guatavita sp. nov., A. mae sp. nov., A. pae sp. nov., A. sie sp. nov., A. sotairensis sp. nov., A. tisquesusa sp. nov. and A. tundama sp. nov.), in the Boyacá and Cundinamarca departments. The eight remaining Andean species are distributed out of this high-Andean plateau, in the Eastern Mountain Range of Boyacá (A. chie sp. nov., A. somondoco sp. nov. and A. sua sp. nov.), Cundinamarca (A. quinini sp. nov. and A. zaque sp. nov.), Huila (A. guaitipan sp. nov.) and Santander (A. zipa sp. nov.) departments, and in the Central Mountain Range of Risaralda department (A. quimbaya sp. nov.). Additionally, A. sikuani sp. nov. is described from the Eastern department of Meta, and A. colombianus sp. nov. and A. tanimuca sp. nov. from the Amazonian department of Vaupés. Finally, a map with these new records is included, along with a short comment about conservation of biota in the Andean region.

Abstract:
Centrolene notostictum Ruiz-Carranza & Lynch,1991 is a glassfrog known from the Cordillera Oriental of Colombia—in the Departments of Boyacá, Cundinamarca, Norte de Santander and Santander (Frost 2017)—and the Venezuelan versant of the Sierra de Perijá (Rojas et al. 2012) from 1600 to 2440 masl. Although males have been found calling on the upper surface of the leaves of ferns and Heliconeaceae on the margins of a small fast-flowing stream (Rojas et al. 2012), no quantitative description of the advertisement call of C. notostictum is currently available. During fieldwork in the Galilea Natural Forest (on the western slope of Cordillera Oriental in the municipality of Villarrica, department of Tolima, Colombia) in 2016 and 2017, we found three vocalizing males of C. notostictum. Herein, we report the first geographic record of this species for the department of Tolima and describe its previously unknown advertisement call.

Abstract:
Cross-sectional descriptive mixed study carried out for the 47 municipalities of the department of Tolima, Colombia, neighboring the department of Cundinamarca, where Bogota, the capital of the country, is located. The objective was to analyze the geographical access barriers and the inventory of human talent and dental services in this department. A distance and time measurement system was applied to identify the duration of travel from each municipality to Ibagué (departmental capital) by public transport. The geographical accessibility barrier determinant endorsed by the World Health Organization (W.H.O.) is a trip duration greater than four hours. It was found that the first level of care in the public sector is present in all municipalities, the second level is in six; the third only in Ibague. Displacement by public transport represents a geographical access barrier in six municipalities; the number of dentists in the public sector does not satisfactorily cover the needs of the population, since more than 50% of the municipalities have a deficit of more than four general dentists and there is a low presence of specialists. In the department of Tolima there are geographical accessibility barriers to health and, specifically, to oral health.

Abstract:
Dendrophidion boshelli is a poorly known and endemic snake species from the Middle Magdalena river valley in Colombia. It was described in 1944 based on a single specimen from the municipality of Caparrapí, department of Cundinamarca. Since the original description, only three additional specimens have been established. As part of the results of a herpetological monitoring in the Miel I Hydroelectric project, department of Caldas-Colombia, three additional specimens of D. boshelli were found in 2014–2015. The specimens represent the second known population of the species. We presented morphological data and pholidosis; description of the coloration in life, and a description of the habitat. Recently, D. boshelli was included as a Critically Endangered (CR) species in the Red Book of Reptiles of Colombia, and the IUCN Redlist. For this reason, to promote the local conservation of this and other endemic and threatened species in the Miel I area, we suggested some actions at the local level, such as establishing a conservation area with legal status in the Middle Manso River basin, which is a tributary of the Miel I Hydroelectric project.

Abstract:
Key words aquatic insects, high-Andean, south-west ColombiaIntroduction The genus Buenoa Kirkaldy has approximately 63 species and is restricted to the Western Hemisphere. In Colombia there are 14 species of Buenoa, and five species are located on the Pacific coast of Colombia in Tumaco, Nariño (PadillaGil, 2010). Buenoa funensis is described; it is the first record of the genus in high-Andean aquatic ecosystems, in the department of Nariño. In the department of Cundinamarca, Padilla-Gil (2002) found four species of Buenoa up to 1800 m above sea level, and just two species, B. pallipes (Fabricius) and B. cucunubensis Padilla-Gil & Nieser, were found at 3000 m. Buenoa funensis constitutes the first recording in Colombia of a large-size species, whose males measure more 8 mm of length; for this reason it is included within the five South American species and B. distincta from Mexico, which present this characteristic; and a key is presented to differentiate males and females of these species based on Nieser et al. (1997).

Abstract:
Two new species, Passiflora splendida and P. quinonesiae of the section Colombiana from the Andes of Cundinamarca Department (Colombia Eastern Cordillera) are described and illustrated. Passiflora splendida is morphologically similar to P. cremastantha of the series Leptomischae, but can be distinguished by its linear stipules, petioles up to 1.8 cm long, lance-ovate leaves (6–8.5 × 2.5–3.3 cm), flowers with a diameter of 9–11 cm long, sepals and petals with intermediate disposition, both longer than the floral tube, floral tube of 3.2–4.5 cm long and fusiform ovary. Passiflora quinonesiae is similar to the species of series Colombianae, most closely related to P. cuatrecasasii and P. lanata. It differs from P. cuatrecasasii by its terete stem, size of the leaves 4.4–15 × 10.3 cm, elliptic bracts and floral tube 5.2–6 cm long. It differs from P. lanata by its ovate leaves, bracts halfway down the floral tube, elliptical sepals and petals, and elliptical ovary. In addition, a taxonomic key to section Colombiana ser. Colombianae and Leptomischae for Colombia is included and information about the ecology, distribution, and conservation status of P. splendida and P. quinonesiae are discussed.

Abstract:
Objective: Geographical information systems (GIS) have been extensively used for the development of epidemiological maps of tropical diseases, however not yet specifically for Zika virus (ZIKV) infection.Methods: Surveillance case data of the ongoing epidemics of ZIKV in the Tolima department, Colombia (2015-2016) were used to estimate cumulative incidence rates (cases/100,000 pop.) to develop the first maps in the department and its municipalities, including detail for the capital, Ibagué. The GIS software used was Kosmo Desktop 3.0RC1®. Two thematic maps were developed according to municipality and communes incidence rates.Results: Up to March 5, 2016, 4,094 cases of ZIKV were reported in Tolima, for cumulated rates of 289.9 cases/100,000 pop. (7.95% of the country). Burden of ZIKV infection has been concentrated in its east area, where municipalities have reported >500 cases/100,000 pop. These municipalities are bordered by two other departments, Cundinamarca (3,778 cases) and Huila (5,338 cases), which also have high incidences of ZIKV infection. Seven municipalities of Tolima ranged from 250-499.99 cases/100,000 pop., of this group five border with high incidence municipalities (>250), including the capital, where almost half of the reported cases of ZIKV in Tolima are concentrated.Conclusions: Use of GIS-based epidemiological maps helps to guide decisions for the prevention and control of diseases that represent significant issues in the region and the country, but also in emerging conditions such as ZIKV.

Abstract:
<p>In order to clarify the distribution of bats of the genus Lasiurus in Colombia, we performed a morphological study of 49 specimens from four Colombian collections. Our review confirms the presence of three species in Colombia (L. blossevillii, L. cinereus, and L. ega) with distribution in all natural regions that include six of the nine biogeographic provinces. These species can be easily differentiated based on external and cranial characters. Lasiurus cinereus is the largest species (forearm length &gt; 52 mm) and L. blossevillii is the smallest (forearm &lt; 42 mm); L. ega has a distinctive skull shape with a developed sagittal crest. While previous literature make claims that L. egregius and L. castaneus occur in Colombia, our analysis found no support for this and even contradicts the evidence cited for their presence in the country. We demonstrate that one specimen attributed to L. egregius in literature corresponds to a misidentified L. blossevillii. Furthermore, we found that there are not any specimens of L. castaneus from the Department of Cundinamarca despite several reports in the literature. The status of subspecies in Colombia remains controversial and more specimens are needed to determine whether there are clear distinctions between forms in any geographical region. Most of the specimens examined were males and in some cases, were collected opportunistically from dead individuals found in cities in the Andean region.</p>

Abstract:
The Nepomorpha and Gerromorpha heteropterans are highly diverse, mainly in Neotropical aquatic ecosystems; however, their composition in the lakes of the Tropical Andes is poorly known. This article presents the composition of aquatic and semiaquatic bugs and their geographical and altitudinal distribution in eight lentic ecosystems from the Cundinamarca department, Colombia. The similar aquatic heteropteran composition between these Andean lakes and its relationship with the geographical and altitudinal range from 1,585 to 3,700 m.a.s.l. in the Eastern Andes are also analyzed. To carry out this work, the collections and pertinent literature are reviewed, and biota similarity is compared by applying a upgma analysis. The results show the predominance of Nepomorpha with a total of 12 species, four genera, and two families: Corixidae (6), and Notonectidae (6). The second most common suborder is Gerromorpha with eight species, seven genera, and five families: Gerridae (3), Veliidae (2), Hebridae (1), Hydrometridae (1), and Mesoveliidae (1). The biota similarity is related to páramo ecosystems and forest type. This article is the first to consider aquatic and semiaquatic heteropterans as biota from the Andean and High Andean lakes in Colombia.

Abstract:
Potato yellow vein virus (PYVV), (family Closteroviridae, genus Crinivirus) is a re-emergent virus in Andean countries. Low inter-isolate variation has been reported for PYVV CP gene, but there are no reports for intra-isolate variation. Inter- and intra-isolate variability in CP from a population of PYVV was studied. Samples of 216 symptomatic potato plants (115 Solanum tuberosum subsp. andigena (STA), 100 Solanum phureja (SPH) and 1 Solanum chaucha (SCH)) were collected in five Colombian departments. Viral isolates were amplified by RT-PCR and the amplicons were analyzed by single-strand conformation polymorphism (SSCP). Six different migration SSCP patterns (A to F) with different complexities were observed among the population. Pattern A was detected in the five departments in 66% of the isolates. Pattern E was found only in the department of Cundinamarca with a frequency of 0.09%. Patterns B, C, D and F were found in similar proportions of from 13% to 5.6% and were present in the five departments. Homology at the nucleotide level of 75% of the sequence of the CP gene was greater than 99% and the dN/dS ratio (no-synonymous/synonymous changes) was 0.002. Amplicons of the whole CP gene of eight selected isolates representing the six SSCP patterns were cloned and the SSCP analysis showed that, in all cases, more than one variant was present. The sequence analysis of the 35 clones confirmed intra-isolate variability of PYVV. The existence of several variants in a single field isolate was demonstrated and negative selection against amino acid changes of the CP was suggested.

Abstract:
ABSTRACT In this study, chemical and microbiological contaminants were detected in fresh fruits and vegetables in peasant markets in the Department of Cundinamarca to assess food safety. At least one pesticide was detected in 63% of the samples evaluated (n = 100, including fruits and vegetables), and in 41% of these, pesticides exceeded the maximum residue limit. Within the pesticides found, 60% do not use a registry from the Instituto Colombiano Agropecuario to be applied on the crops where they were detected and are included in the toxicological categories “highly toxic” (category IB) and “moderately toxic” (category II). Heavy metals were found in 45% of the samples, with cadmium (38%) and lead (14%) being the most frequent. The pathogenic microorganisms Escherichia coli O157:H7, Listeria monocytogenes, Salmonella, and Campylobacter sp. were detected in 4, 2, 1, and 0% of the samples, respectively. Factors concerning integrated crop management, contaminated inputs with chemicals and microorganisms, and the lack of hygiene in the postharvest stage favor the presence of pesticide residues, heavy metals, and the appearance of pathogenic microorganisms. The results suggest the need to strengthen the implementation of integrated management strategies that guarantee the safety of fresh fruits and vegetables in the country. HIGHLIGHTS

Abstract:
Background Pandi’s mushroom-tongue salamander (Bolitoglossa pandi) is one of the threatened amphibians in South America, as well as a flagship species for the Colombian conservation agenda. This species is endemic to the Andean cloud forests of the western slope of the Cordillera Oriental of Colombia, occurring only in the department of Cundinamarca within a narrow elevational range. At night, B. pandi can be seen perching on the upper side of leaves at heights ranging from ground level to 2.5 m. During the day, it can be found under leaf litter or cover objects. Few studies have provided relevant information that can help the Colombian government to formulate lines of action for the conservation of this species; consequently, its threat assessments so far have been based on very limited information. Methods We conducted surveys for salamanders in four municipalities of Cundinamarca, Colombia, using two approaches: visual encounter surveys (Guaduas and Villeta) and the basic sampling protocol for single-species occupancy modeling (Supatá and Venecia). Multivariate analyses were employed to explore the correlation between habitat structure and natural history traits, abundance, and detection/non-detection of B. pandi. We evaluated the B. pandi activity pattern through kernel density curves for each sampling occasion and explored the variability of salamander abundance during their activity period by performing a nested ANOVA. Results We report the discovery of two new populations of B. pandi, which represent the most northwestern records known. A significant correlation between body length, body mass, and habitat structure was observed. Multivariate analyses indicated that leaf litter depth, mean temperature, percent vegetation cover, and altitude were the habitat variables that together explained 60.3% of the B. pandi abundance variability, as well as the main determinants of its optimal habitat. Bolitoglossa pandi exhibits an activity pattern characterized by two main activity peaks, in which niche time-partitioning was observed. Across the surveyed area, we found a healthy, stable, highly dense population of B. pandi (>1,300 individuals), with seasonal variability between development stages. Discussion Given the high habitat specificity of B. pandi, the species is highly vulnerable to local changes. Thus, we recommend that B. pandi be retained as Endangered (EN) on the IUCN Red List, based on the IUCN Criterion B, given its restricted extent of occurrence (ca. 2,500 km2) and the ongoing threats from agriculture, cattle ranching, logging, and urban development, which continue to reduce its suitable habitat.

Abstract:
This text aims to describe a methodological proposal to identify, classify, and organize the faunistic knowledge of students of rural schools. The research was conducted with twenty sixth graders from a rural school in the Department of Cundinamarca, Colombia. Through five types of activities, they expressed, in different ways, their knowledge about the animals of the region. The information collected was organized, categorized, and systematized in tables; these tables resulted from the analysis of the information the students provided. It is a possibility of school work that favors the recognition and valuation of the traditional and ancestral knowledge, and its incorporation to the dynamics of the teaching and learning of the Natural Sciences as a way to create “bridges” between that knowledge and the scholarly scientific knowledge. It is a proposal that, among other things, favors the development of more positive attitudes toward science itself, motivates students to ask questions, to recognize the importance of the cultural context, and to recognize themselves as part of a biocultural system.

Abstract:
ABSTRACT The post-harvest quality of pineapple guava fruit is determined by the storage and prevailing weather conditions during growth and development. This study proposes a model for post-harvest fruit quality according to the storage and weather conditions in the pineapple guava growing region. Physiologically ripe fruit were collected during two harvests from two locations within the Department of Cundinamarca (Colombia): Tenjo and San Francisco de Sales. The fruits were stored at 18 ± 1 °C (76 ± 5% relative humidity (RH), over 11 days) and at 5 ± 1 °C (87 ± 5% RH, over 31 days), and the quality attributes were evaluated every two days. Models of the most significant physio-chemical quality characteristics of the post-harvest fruit were developed by using the Excel® Solver tool for all data obtained in the two crop periods. The results showed that storage and prevailing weather conditions, which differed according to the altitude of the growing site, had considerable impacts on the physio-chemical characteristics of the fruit throughout the post-harvest ripening process.

Abstract:
The quality of pineapple guava fruits during post-harvest storage depends directly on their quality at harvest and is influenced by climatic conditions during growth. The aim of this study was to determine the influence of climatic conditions on certain parameters of fruit quality during post-harvest storage. Twenty trees were tagged in two locations within the department of Cundinamarca (Colombia), recording the climatic conditions during fruit growth until harvest. The fruits were differentiated by place of origin and stored at 18 ± 1ºC (76 ± 5% relative humidity, RH) for 11 d or 5 ± 1ºC (87 ± 5% RH) for 31 d, evaluating several quality attributes every two d. The places of origin were San Francisco de Sales (1,800 m a.s.l., 20.6oC, 63-97% RH, with an average annual precipitation of 1,493 mm) and Tenjo (2,580 m a.s.l., 12.5oC, 74-86% RH, with an average annual precipitation of 765 mm). The results indicated that the fruits stored at the highest temperature were sweeter and had reduced weight and firmness, lower acidity, and faster postharvest senescence (lower post-harvest durability). The postharvestN fruit characteristics were determined by considering the fruit quality during growth and the influence of climatic conditions during cultivation in each location. At the higher altitudes, the total soluble solid content in the fruits was higher and firmness decreased, and the total titratable acidity and weight loss were lower. For fruit color, significant differences were not observed that would demonstrate the effect of climatic conditions during the post-harvest period.

Abstract:
<p><em>Tecia solanivora </em>es una de las plagas más limitantes del cultivo de la papa, para cuyo control el uso de granulovirus constituye una alternativa promisoria. Para el control de la plaga en condiciones de almacenamiento, en Colombia se produce un bioplaguicida en polvo a base de un granulovirus aislado en Perú a partir de larvas de <em>Phthorimaea operculella</em>. En un trabajo previo se aislaron tres granulovirus nativos provenientes de larvas de <em>T. solanivora </em>de los municipios de Chocontá, Mosquera y Carmen de Carupa en el departamento de Cundinamarca, los cuales podrían estar mejor adaptados al insecto y a las condiciones ambientales del país. En el presente trabajo, los tres aislamientos de granulovirus se evaluaron mediante un bioensayo en laboratorio utilizándolos formulados y sin formular y teniendo como patrón de comparación la cepa peruana. Los virus nativos formulados presentaron eficacias entre 88% y 100%, mientras que para el aislamiento peruano se obtuvo 88%. Estos resultados fueron significativamente diferentes de los obtenidos con los aislamientos sin formular, para los cuales la eficacia estuvo entre 36% y 86% para los aislamientos nativos y, 59% para el aislamiento peruano. También se comparó la cantidad de cuerpos de inclusión (CI) producidos por miligramo de larva con cada uno de los aislamientos, entre los que no se encontraron diferencias significativas. El rendimiento promedio fue de 4,4 x 107 CI/mg de larva. Los resultados permitieron seleccionar el aislamiento nativo proveniente de Mosquera (Cundinamarca) para el futuro desarrollo de un bioplaguicida por presentar los mayores niveles de virulencia. </p><p> </p><p><strong>Comparison of the efficacy and yield of three native granulovirus over </strong><strong><em>Tecia solanivora </em></strong><strong>(Povolny) (Lepidoptera: Gelechiidae) larvae</strong> </p><p><em>Tecia solanivora </em>is one of the most limiting potato pests and the use of granulovirus constitutes a promissory alternative for its control.

These native strains could be better adapted to both the host and the environmental conditions of the country. In the present work the three native isolates of granulovirus were evaluated formulated and unformulated under laboratory conditions by using a bioassay and were compared with the Peruvian strain. The formulated native viruses presented the highest efficacy with results between 88% and 100%, while the Peruvian isolate obtained 88%. These results were significantly different from the obtained with the unformulated virus isolates, for which the efficacy ranged between 36% and 86% for native isolates and was 59% for the Peruvian strain. The concentration of occlusion bodies (OB) produced per milligram of larva tissue was measured and no significant differences between the isolates were observed. The average yield was 4.4 x 107 OB/mg larvae. Results allowed to select the native isolate from Mosquera (Cundinamarca) for a future biopesticide development for presenting the highest virulence levels. </p>

Abstract:
The growth of the pineapple guava fruit is primarily stimulated by temperature but is also influenced by other climactic factors, such as altitude. The goal of this study was to develop a growth model for the pineapple guava fruit as a function of thermal time (GDD, growing-degree day) and altitude (H) of the production area. Twenty trees per farm were marked in two sites in the Cundinamarca department (Colombia) during the 2012 and 2014 seasons. The measurements were performed every seven days after day 96 and 99 post-anthesis until harvest in the sites of Tenjo (2,580 m.a.s.l.) and San Francisco de Sales (1,800 m.a.s.l.), respectively. A growth model was produced for weight as a function of fruit length and diameter as well as for the weight of the fruit as a function of GDD and H, with this last measure adjusted to a sigmoidal logistic growth model. The parameters for the regression analysis showed that the models satisfactorily predicted fruit growth for both of the sites, with a high determination coefficient. The cross-validation showed good statistical fit between the predicted and observed models; the intercept was not significantly different than zero, and the slope was statistically equal to one.

Abstract:
The Asian citrus psyllid Diaphorina citri is the insect vector of the disease known as huanglongbing (HLB), which is the most devastating disease of citrus crops in the world. The Asian citrus psyllid was officially reported in Colombia in 2007, and a national phytosanitary emergency was declared because of the presence of HLB in 2015. Two different experiments were carried out in two locations (Apulo and Jerusalén, Department of Cundinamarca) in Colombia to evaluate the effectiveness of neonicotinoid (clothianidin, imidacloprid and thiamethoxan) and pyrethroid applications (bifenthrin, deltamethrin and lambda cyhalothrin) on the control of D. citri populations (adults, nymphs and eggs) in ‘Tahiti’ lime trees established under tropical dry forest conditions. In the first experiment, trees were foliarly treated as follows: (1) untreated trees; (2) trees treated with 100 g ha-1 of imidacloprid; (3) trees treated with 60 g ha-1 of bifenthrin; (4) trees treated with 12.5 g ha-1 of deltamethrin and (5) trees treated with a co-formulation of 70 g ha-1 of a neonicotinoid (thiametoxan) and 53 g ha-1 of a pyrethroid (lambda cyhalothrin). In the second experiment, trees were treated with 100 g ha-1 of clothianidin. Foliar insecticide applications were carried out at 0 and 4 weeks after the initiation of treatments (WAT). In the first trial, the control presented a mean number of individuals per flush of ≈1.14, whereas the trees treated with neoinicotinoids and pyrethroids showed 50% fewer individuals (0.53-0.61). For the population of immatures, the number of nymphs was 2.25 nymphs per flush in the control, as compared to 0.82-1.22 individuals observed in the treatments with insecticides. The mean number of eggs was also between 80-100% higher in the control trees (2.37 individuals), as compared to the treated trees (1.14-1.78). In the second trial, the use of clothianidin showed a higher control of eggs. The results suggest that the rotation of neonicotinoids with pyrethroids can be a tool to reduce populations and delay resistance processes in D. citri in citrus trees established under tropical dry forest conditions in Colombia.

Abstract:
The giant African snail is currently one of the most aggressive and invasive species that has colonized many countries outside its natural environment. We recorded four shell measures and the weight of 3 157 individuals of Achatina fulica collected in Boyacá, Cundinamarca, Meta, Norte de Santander and Valle del Cauca, Colombia. Larger and heavier individuals were collected in the Meta and Boyacá departments while the highest density per square meter was recorded in Cundinamarca. We found a strong, positive and highly significant (p<0.01) correlation among measured variables. During development maximum sizes of shell, opening and body weight are correlated, and shell length increases faster than the other measures, leading to a marked elongation of the individuals. The settling time of the populations was also reflected in the size of individuals.

Abstract:
Abstract The spectacled bear (Ursidae: Tremarctos ornatus) is an emblematic umbrella species and one of the top carnivores in the Andean mountains. It is also listed as vulnerable by IUCN and as endangered by CITES. We analyzed the genetic structure of this species in nine geographical regions representing the three Andean Cordilleras in Colombia. We sequenced six mitochondrial genes in 115 spectacled bears; a subset of these specimens (n = 61) were genotyped at seven nuclear microsatellites. We addressed three objectives: 1) determine the genetic diversity and historical demographic changes of the spectacled bear in Colombia; 2) determine phylogeographic patterns of genetic divergence among spectacled bear populations in Colombia; and 3) estimate the levels of gene flow among different regions of Colombia. Our analyses show evidence of high mitochondrial genetic diversity in spectacled bears, both in Colombia as well as in each of the nine regions, most particularly Norte de Santander, Nariño, and Antioquia-Córdoba. In addition, we detected population expansion in Colombia that occurred around 24,000 years ago, followed by a population decrease during the last 7,000 years, and a sudden expansion in the last 300 years. Phylogenetic analyses showed few well-supported clades, with some haplotypes detected in all the departments and Colombian Andean Cordilleras, and other haplotypes restricted to certain geographical areas (Antioquia, Norte de Santander, Cundinamarca, and Nariño). We detected significant genetic heterogeneity among some departments and among the three Colombian Andean Cordilleras for both mitochondrial and nuclear genes. Nevertheless, the moderate levels of gene flow estimated from FST statistics suggest that geographical barriers have not been definitive obstacles to the dispersion of the spectacled bear throughout Colombia. Despite these gene flow estimates, significant spatial autocorrelation was detected for spectacled bear in Colombia, where two kinds of spatial patterns were discovered: genetic patches of 144 km of diameter, and isolation by distance among bears separated from 578 to 800 km. The two most northern spectacled bear populations of Colombia (Norte de Santander and Antioquia) also were the two most differentiated. Their distinctiveness may qualify them as distinct Management Units (MUs) in the context of conservation policies for the spectacled bear in Colombia.

Abstract:
The cape gooseberry (Physalis peruviana L.), a fruit species cultivated in the Andes, is one of the major fruit exports of Colombia. We hypothesized that the Andean cordilleras in Colombia play a role in structuring the genetic diversity of this crop. For addressing this hypothesis, a set of 85 Colombian cape gooseberry accessions from different departments and cordilleras was analyzed by means of 15 SSR markers. AMOVA, clustering and Bayesian analyses were applied. The results showed the presence of two major groups related to geography: one consisting of cultivated and non-cultivated accessions from the eastern Andes (Norte de Santander, Santander, Boyaca and Cundinamarca) and the other one consisting of cultivated and non-cultivated accessions from the central and western Andes (Antioquia, Caldas, Cauca and Nariño). The genetic relationships between the accessions suggested that the movement of cape gooseberry seeds may be more frequent between neighboring regions, thus explaining the existence of these two major groups. The results also showed lower levels of genetic diversity in this sample (HE=0.223), as compared to other Physalis species and other studies on the cape gooseberry that used different molecular markers. It is recommended that future evaluation studies include both cultivated and non-cultivated genotypes from the two major groups detected in this study in order to better represent the genetic diversity available in this crop.

The recently described Ananteris hasshy Teruel & Roncallo, 2008 is synonymized under Ananteris columbiana Lourenço, 1991 based on several evidences from morphology. The males of Ananteris dorae Botero-Trujillo, 2008, Ananteris ehrlichi Lourenço, 1994 and Ananteris myriamae Botero-Trujillo, 2007, and the female of Ananteris arcadioi Botero-Trujillo, 2008 are described for the first time. Ananteris meridana González-Sponga, 2006 is reported for the first time for Colombia and the genus Ananteris for the departments of Cundinamarca, Santander and Norte de Santander. Likewise, new locality records are given for A. arcadioi, A. dorae and A. myriamae. Revised diagnoses and data on intraspecific variability are provided for A. arcadioi, A. columbiana, A. dorae, A. ehrlichi, A. meridana and A. myriamae. Hemispermatophore morphology is described for the first time for A. arcadioi, A. columbiana, A. dorae, A. ehrlichi, A. meridana, A. myriamae, A. ochoai sp. nov. and A. solimariae sp. nov., providing evidence of this structure’s taxonomic usefulness and revealing a paramount need to describe it in further taxonomic works on Ananteris. Some notes on the use of the fixed finger trichobothria for the definition of Ananteris speciesare provided. A distribution map plotting the known locality records of the thirteen Colombian species of Ananteris and a key to their identification are also included. Finally, the name ‘Ananteris antioquensis’, used by Otero et al. (2004) but never published, is herein deemed a nomen nudum.

Abstract:
Salmonella Paratyphi B dT+ variant (also termed Salmonella Java) and Salmonella Heidelberg are pathogens of public health importance that are frequently isolated from poultry. As a step toward implementing the Colombian Integrated Program for Antimicrobial Resistant Surveillance, this study characterized molecular patterns of Salmonella Paratyphi B dT+and Salmonella Heidelberg isolated from poultry farms, fecal samples, and retail chicken meat using pulsed-field gel electrophoresis (PFGE). The objective of this study was to determine the genetic relationship among isolates and to determine potential geographically predominant genotypes. Based on PFGE analysis, both serovars exhibited high heterogeneity: the chromosomal DNA fingerprints of 82 Salmonella Paratyphi B dT+ isolates revealed 42 PFGE patterns, whereas the 21 isolates of Salmonella Heidelberg revealed 10 patterns. Similar genotypes of both serovars were demonstrated to be present on farms and in retail outlets. For Salmonella Paratyphi B dT+, closely genetically related strains were found among isolates coming from different farms and different integrated poultry companies within two departments (Santander and Cundinamarca) and also from farms located in the two geographically distant departments. For Salmonella Heidelberg, there were fewer farms with genetically related isolates than for Salmonella Paratyphi B dT+. A possible dissemination of similar genotypes of both serovars along the poultry production chain is hypothesized, and some facilitating factors existing in Colombia are reviewed.

Abstract:
Citrus huanglongbing (HLB) is the most destructive citrus disease. Two of the three known HLB-associated CandidatusLiberibacter species were recently found to be present in the Americas. In this study, eggs, nymphs and adults of Diaphorinacitri Kuwayama (Hemiptera: Liviidae) and suspect citrus plant materials were collected in 25 municipalities in the departments of Cundinamarca, Santander, Valle del Cauca, Meta and Quindio (Colombia). The detection sensitivity, specificity and assay performance of the 16S rDNA-based real-time PCR (qPCR) were validated for the field survey of the disease in Colombia. The validation confirmed the reliability and robustness of the real-time PCR method for the detection of HLB bacteria in host citrus plant tissues and the vector D. citri. The diagnosis was performed for Candidatus Liberibacter asiaticus (Ca. L. asiaticus) and for Candidatus Liberibacter americanus (Ca. L. americanus) on 168 citrus plant material samples and 239 insect samples. Neither Ca. L. asiaticus nor Ca. L. americanus were detected in the host plants or insects vector, confirming the absence of the disease in the citrus-producing areas of Colombia.

Abstract:
Background Multiple myeloma (MM) is a heterogeneous and incurable disease that evolves from asymptomatic premalignant conditions. The worldwide incidence, prevalence and mortality are well known thanks to data reported by the International Agency for Research on Cancer (IARC) and by the GLOBOCAN World Cancer Observatory. The data provided by Colombia to these reports comes from the population cancer registries corresponding to 5 cities whose most up-to-date data are from 2018. National data can also be found in the base of the high-cost account. Although it is true that there are excellent sources of information, it is believed that there is a significant underreporting of the prevalence of the disease, which makes it necessary to optimize the information to achieve the establishment of programs oriented to work on better control of this type of hematological cancer. The study MiMENTe (Mieloma Múltiple Epidemiología Nacional y territorial) is a collaborative effort to know the reality of the disease in terms of incidence, prevalence and mortality in Colombia as a first step to control the disease even in the premalignant stages for the future wanting to position itself as a model for the control of MM in developing countries. Methods MiMENTE (Mieloma Múltiple, Epidemiología Nacional y territorial) is a multiphase study that is going through its first stage through a cross-sectional study in Colombia. The total population diagnosed with Multiple Myeloma (ICD Code 10 C900) during the 2008-2018 period was included in the RIPS Individual Service Delivery Registry in Colombia and a comparison was made with the available data from GLOBOCAN (Global Cancer Observatory) and High Cost Account. Records that had an unidentified diagnosis were excluded. For this phase, a comparison is made of the data from the registries of the three entities described, three measures of frequency are established: Incidence, prevalence and mortality, standardizing the latter by means of a direct method, making the Colombian population comparable with large countries such as the United States. and Spain cataloged as centers of reference in the management and diagnosis of Multiple Myeloma. Variables such as ethnicity, age, place of origin, health regime, place of death will be studied in the future in later phases of the study. Results Between 2009 and 2018 (10 years), 26,356 MM diagnoses were found throughout the national territory of Colombia. The departments where the most attention to patients with this diagnosis was presented were Cundinamarca, Valle del Cauca, Antioquia, Santander, Bolívar and Atlántico Figure 1. The standardized incidence rate for Colombia in 2018 was 1.79 x 100,000 inhabitants, being higher in the Andean region as shown in the heat map. Graph 1. The total number of prevalent cases per year varied from 1138 cases in 2009 to 4474 cases in 2018 being for this year the adjusted prevalence of 8.97 x 100,000 inhabitants / year Graph 2. When the prevalence is analyzed by regions it is higher in the Andean region Graph 3. During this entire period of time, 5481 deaths were found, being 20.80%. The highest mortality occurred in the departments of Vichada, Meta, Caquetá, Risaralda, Atlántico and the island of San Andrés. Figure 2. The age-standardized mortality rate for Colombia is 1,39x100,000 inhabitants (Adjusted with the population of the United States). The most up-to-date data from IARC and GLOBOCAN are those corresponding to the year 2018. A comparison was made of our data with those reported in this last registry for Colombia in addition to the high-cost account. Comparative data were developed with the population of the United States, standardizing this population and it was also compared with the data reported for Spain. The prevalence of the disease is higher in Colombia than reported by GLOBOCAN, IARC and High cost drug account Table 1. Conclusion This is the first report of the MiMENTe study that shows the incidence, prevalence and mortality of patients with 10-year-old multiple myeloma in Colombia. The prevalence of the disease is higher than that reported by international registries. The regions with the highest incidence were those belonging to the andean region. The highest prevalence was confirmed in Bogotá and Antioquia and the highest mortality was observed in the Orinoco region.

Abstract:
AbstractThe low availability of pollinators in high-elevation ecosystems can lead to flowering plants showing different adaptive responses in order to assure their reproductive success. Shifts toward autogamy and asexual reproductive rates (the reproductive assurance hypothesis) and the compensatory measures to maintain outcrossing such as flower longevity and more prolonged pistil receptivity (the increased pollination probability hypothesis) are some of these responses. Several studies have tested both hypotheses, but investigations of plants of tropical alpine environments such as paramos that support these assumptions are still scarce. Puya nitida, an endemic Colombian plant species distributed in the paramo and subparamo in the Eastern Cordillera of Cundinamarca department, was used as a case study to test its reproductive characteristics that assure its sexual reproduction. We analysed the species’ floral morphology and development, its phenological patterns and its plant mating-system. We found that Puya nitida showed floral characteristics that promote pollination by birds, herkogamy and dichogamy, flowers and receptive stigmas with 9 and 12 days of longevity, respectively and an index of self-incompatibility that shows that it is mostly self-incompatible. We found a synchronic phenological pattern with an annual frequency and an intermediate duration with a peak in the period of lowest rainfall. Our results suggested that longer floral development, prolonged stigma receptivity, herkogamy and dichogamy and self-incompatibility might assure reproductive success, since the cross-pollination might be favoured when few pollinators are in attendance. Overall, these reproductive mechanisms add evidence to the increased pollination probability hypothesis, specifically for a plant species of a tropical high-elevation ecosystem where pollinators are scarce.

Abstract:
Thrips samples were collected from cotton crops in the Andean region of the Magdalena warm valley, an area represented by the Colombian departments of Tolima, Huila and Cundinamarca. Ten cotton plants were randomly selected per hectare in each plot. Five young leaves, five floral buds, five opened flowers and five bolls or fruits were inspected. Immature stages were separated from the adults and a first classification was made according to the present thrips morphotypes, separating the adults of possible S. dorsalis specimens from the others. T-Student and Kruskal-Wallis tests were performed in order to find statistical differences between the different evaluated variables. The selectivity of S. dorsalis for each plant structure was determined by Z tests, Spearman correlation analysis and the Bray-Curtis similarity index. Scirtothrips dorsalis was found in 77% (n = 46) of the inspected sites. The species exhibited greater affinity to the boll, followed by young leaves and buds. Opened flowers constituted a resource not frequented by the pest with a similarity range of I = 0.8 (<1). It is suggested that cotton plants are hosts to the thrips species; it means that the pest life cycle is highly associated to the cotton production in the Andean region. The importance of the results related to the cotton production and other crops associated to the insect species in the region is discussed.

Abstract:
The lichenized genus Graphis sensu Staiger (Graphidaceae) is listed with 67 species in the most recent version of the Catálogo de Plantas y Líquenes de Colombia. Revision of recent publications and approximately 700 collections housed in the Cryptogams Section of the Herbario Forestal “Gilberto Emilio Mahecha Vega” of the Universidad Distrital Francisco José de Caldas in Bogotá revealed 70 additions to the Colombian lichen biota in this genus and the recently segregated genus Allographa, including 13 species new to science, from the departments of Boyacá, Casanare, Cauca, Cesar, Cundinamarca, Meta, Nariño, Santander, and Tolima. In this paper, six new species of Graphis with transversely septate ascospores are described, illustrated, and discussed. The new taxa are: Graphis amaliana, with lirellae becoming striate, laterally carbonized excipulum, clear hymenium, large, transversely septate ascospores, and norstictic acid; differing from Allographa celata and A. verminosa in the verrucose thallus and erumpent lirellae with verruculose thallin margin, as well as in the broader ascospores; G. carmenelisana with labia becoming striate, completely carbonized excipulum, inspersed hymenium (type A), large, transversely septate ascospores, and stictic acid; differing from Graphis gloriosensis in the rugose-verruculose thallus and the radiately branched lirellae with apically thin complete thalline margin and labia becoming striate; G. kavintuca with entire lirellae, laterally carbonized excipulum, clear hymenium, small to medium-sized, transversely septate ascospores, and lacking substances; differing from A. elongata in the lirellae lacking a thalline margin and from A. nana in the larger ascospores and the longer, flexuose lirellae; G. rosalbinana with lirellae becoming striate, completely carbonized excipulum, clear hymenium, small, transversely septate ascospores, and norstictic acid; differing from G. schiffneri in the shape and disposition of the lirellae; G. santanderiana with entire lirellae, laterally carbonized excipulum, clear hymenium, small, transversely septate ascospores, and lacking secondary substances; differing from G. imshaugii in the laterally carbonized excipulum and lack of secondary substances; G. solmariana with entire lirellae, laterally carbonized excipulum, clear hymenium, large, transversely septate ascospores, and stictic acid; differing from G. sitapurensis in the basal thalline margin and the broader ascospores. A remarkably high number of new species are from high altitude andine forest and paramo, habitats previously not believed to be rich in Graphis species.

Abstract:
The first formal attempt for medical education in Valle del Cauca was in the Faculty of Medicine and Surgery in Buga, which was part of the Colegio Académico between 1866 and 1871. It only had one graduating class of ten physicians in 1871. Its foundation was contemporaneous with the faculties of medicine at Universidad de Antioquia and Universidad del Cauca; the reasons for its prompt disappearance are unknown. The professional training concerns of the región were maintained through the creation of the Sociedad de Medicina del Cauca (Cauca Medical Society) in 1887, which gave rise to the Boletín de Medicina del Cauca (Cauca Medical Newsletter) (1887-1910) which published the works of Evaristo García and his partners Daniel Quijano Wallis, Pedro Pablo Scarpetta, Agustín Escobar, Enrique Garcés, Adolfo Tenorio, and Pablo García Aguilera, among others. The need to create a school of medicine in Cali was aired since the 1940s among trade groups at the Colegio Médico del Valle (Valle Medical School), although some thought that the warm climate in Cali was not suitable for intellectual development because such required cold environments like those in the Cundinamarca and Boyacá plateau. History managed to reveal how wrong these believers of geographical determinism were. The Humphreys Mission, commissioned by the National Government in 1948, delivered a bleak report (1950) on medical education in Colombia suggesting the creation of new medical faculties, among them one in Valle del Cauca. Guillermo Orozco, a physician from Anserma and living in Cali, with support from the Colegio Médico del Valle, managed to get the Governor, physician Antonio Lizarazo, to expedite Decree 641 of 1950, ordering the creation of a faculty of medicine affiliated to the recently created Universidad del Valle. The University had been founded in 1945 with the name of Universidad Industrial del Valle del Cauca; the name was changed in 1954 to Universidad del Valle when the Dean of Medicine, Dr. Velásquez, was designated Departmental Secretary of Education. With support from Carlos Arturo Cabal, then Rector of the University, in November 1950, the Governor named Dr. Gabriel Velásquez Palau, a physician from Cali, as Dean of Medicine. Classes began on the 12th of October of 1951 with fifty students at the former convent of San Agustín already converted to Colegio de Santa Librada, located in Carrera 4 with calle 13; the medical practices took place at the San Juan de Dios Hospital. Excited by the collective dream of accomplishing a change in medical education, prestigious professors started arriving in Cali from many latitudes like Jorge Araújo Grau, Luis María Borrero, Plutarco Naranjo, Pelayo Correa, Carlos Restrepo, Jorge Escobar Soto, Miguel Gracián, Jaime Korgi, Carlos León, Lupi Sergio Mendoza, Santiago Rengifo, Vicente Rojo, and Carlos Sanmartín, among others. This group of adopted «Caleños» joined prestigious local physicians, many of them trained abroad with support from the Kellogg and Rockefeller Foundations, until forming a critical mass, a sort of athenaeum of the enlightened, which would change the Colombian and Latin American educational model, and even influence on the global educational model.

Abstract:
Abstract Amblyomma nodosum is a Neotropical tick species distributed from Mexico to Argentina, with adult individuals infesting different mammal species, including anteaters (Pilosa: Myrmecophagidae). Few reports in Colombia have recorded this species in departments such as Meta, Tolima and Valle del Cauca. In this paper we describe this species using taxonomic, morphometric and molecular methods after collecting individuals parasitizing collared anteaters (Tamandua tetradactyla) in the departments of Cundinamarca and Tolima. Adult specimens were identified based on current taxonomic keys and different morphometric variables were documented in nonengorged individuals. Also, DNA was extracted for PCR amplification and sequencing of 16S rDNA, COI and ITS2 genes. Phylogenetic trees were built. One hundred and thirty-four adult ticks were collected and identified as Amblyomma nodosum, based on morphological, morphometric, molecular and phylogenetic analyses. This is the first study to report the presence of this tick species in the department of Cundinamarca, using multiple identification approaches, thus expanding its geographical records in Colombia.

Abstract:
The bacteriosis and moko of plantain are ones of the most important phytosanitary problems in the production of musaceae in Colombia. To contribute to the management of these diseases in the department of Cundinamarca, soils and foliar tissues were analyzed, as well as the symptoms of the diseases in 149 farms of producers in the municipalities of Chaguani, La Palma, La Vega, and Viota (Cundinamarca). A descriptive analysis of the chemical properties of soils and foliar concentration of nutrients was carried out; the Student-Welch t-test was applied (P<0.05); the distribution patterns of the diseases were represented cartographically. According to the results obtained, the sampled soils are not saline, they have extreme to strong acidity, low effective cation exchange capacity and low fertility; meanwhile plants show a deficit of elements such as nitrogen, phosphorus, sulfur, copper, zinc, and boron. Considering the total number of farms evaluated, the incidence of bacteriosis and moko disease was reported in 63 and 14% at the departmental level, respectively. A higher concentration of sulfur and zinc was observed in farm soils free of both diseases. Finally, plants reported as free of bacteriosis showed a higher concentration of potassium and lower concentrations of calcium and manganese; while plants reported as free of moko disease showed higher concentrations of nitrogen, sodium, and copper, and a lower concentration of calcium. The results obtained contribute to the planning of large-scale management strategies, in order to reduce the risk of dissemination of diseases of economic importance for plantain crop.

Abstract:
Due to the high susceptibility of strawberry fruits to the attack of pests and diseases, a large amount of pesticides is applied during the crop cycle and harvest period. The inadequate use of these substances can generate residuals in agricultural products, which, through intake, pose a risk to human health. The objective of this study was to determine and compare the pesticide residues in strawberry fruits from two different production systems, distributed in the main producing areas of the Cundinamarca Department (Colombia). Eight samples of strawberry crops were collected in four producer municipalities (Guasca, Facatativa, Mosquera and Sibate), two to compare different systems (conventional production vs. production based on the Integrated Pest Management, IPM). Samples at a concentration of 394 molecules were examined by liquid and gas spectrometry. Fisher's exact test was used to determine the association between crop practices and the residual level in fruits. Twenty two different molecules were detected for the samples analyzed, with 37 detection events, of which eight were reported in IPM production systems and 29 in conventional producers. Results revealed a total of two molecules at excessive concentrations after Colombian regulations. Significant differences were found between the two production systems. This is attributable to the producers´ lack of knowledge and understanding about conventional management in Good Agricultural Practices, and the concepts of pesticide restriction period and residuality.

ABSTRACT Lettuce is the most cultivated leafy salad vegetable in Colombia, being the municipality of Madrid, in the Department of Cundinamarca, the second largest producer. In this region, lettuce plants with foliar symptoms characterized by brown necrotic spots forming an extended necrotic area, chlorosis, leaf distortion and plant stunting have been detected, possibly caused by a viral infection associated with the Orthotospovirus genus. This study aimed to identify the orthotospovirus species associated with those symptoms, contributing to updating the lettuce phytosanitary status in this region. The presence of orthotospovirus was confirmed by the enzyme-linked immunosorbent assay (DAS-ELISA), although the sequence of the nucleocapsid (N) gene confirmed the presence of Alstroemeria necrotic streak orthotospovirus, disregarding the Tomato spotted wilt orthotospovirus and Impatiens necrotic spot orthotospovirus previously reported for this crop, being this its first report in lettuce crops in Colombia.

ABSTRACT Objectives. Determine the presence and the type of endoparasites with zoonotic potential in swine and human of two technified and two semi-technified farms in the department of Cundinamarca, Colombia. Materials and methods. Three serial samplings of feces were taken in a pen row within intervals of 15 days, in two technified and two semi-technified farms in different age groups distributed as follows: pregnant-sows, nursing-females, boars, weaners, suckling-piglets, and growing-pig. By means of informed consent thirty-three people agreed to enter the study. Thirty-three samples from men and women of different ages were received. The pool and individual samples of fecal were evaluated by direct analysis, qualitative flotation and sedimentation techniques and modified Ziehl- Neelsen stain. Results. For the porcine population, on the average, the results obtained from both technified farms showed that Balantidium coli (42%), Endolimax nana (21.9%) and Iodamoeba bütschlii (7.8%) were the most common parasites. In semi-technified farms they were: Entamoeba coli (40%), Endolimax nana (35%), Iodamoeba bütschlii (25%) and Balantidium coli (5%). By means of the test chi2 it is possible to conclude that there is a significant difference between the parasites species and the type of farm. The results obtained in human showed the presence of parasites as: E. coli (42.2%), Entamoeba hystolitica/dispar (12.1%), E. nana (9.1%), B. coli (9.1%), I. bütschlii (3.0%) and Blastocystis hominis (3.0%). Conclusions. The presence of parasites such as Balantidium coli, Endolimax nana, Iodamoeba bütschlii and Entamoeba coli in swine and human suggests a possible rotation of parasitic species between hosts.
