Abstract:

Canary (Serinus canarius) is one of the most beautiful cage birds. They are small and delicate songbird species. Their origin is the Canary Islands in the Atlantic Ocean. They were first brought to Europe by the Spanish sailors in 1478. Than Britain, Germany, France, Netherlands and Italy were started professional canary breeding. The wild ones live in flocks, mostly on the edge of wooded lakes and creeks. While the color of canaries grown in cages is completely yellow, the wild ones are gray-green. Sound in the wild canary is stronger and more impressive. There are 3 types of canaries commonly produced. These are “Song canaries”, “Color canaries” and “Form canaries”. Nowadays they are often produced for their beautiful color and sound. This article gives brief information about canaries and to provide resources to enthusiasts who want to do produce has been prepared.

Abstract:

Red wine produced from Listán Negro and Negramoll grapes from the Canary Islands (Spain) was firstly aged in new American and French (Allier) oak barrels in order to measure composition and sensory changes during 21 months. Aging resulted in an increase in titratable and volatile acidity and a decrease in ethanol concentration with a greater evaporation in the American oak samples. Initially, there was also an increase in color density due to the polymerization of anthocyanins. Extraction of total phenols was greater in the French barrels.

Abstract:

Previous research has shown that acoustic experiences in early life influence song preferences in female domesticated canaries, Serinus canaria. We do not know, however, if they can modify song preferences in adulthood. In the experiments reported here, one group of young female domesticated canaries was reared in acoustic isolation in early life without song tutoring, while two groups were tutored with a playback song (one with wild canary song and one with domesticated canary song). We tested these three groups of females once they had reached adulthood, prior to breeding, using copulation-solicitation displays as an index of their song preferences. The females were then placed in an aviary with males during the breeding period, after which they were retested. We observed that the song preferences of females reared in acoustic isolation and those tutored with wild canary song had changed. These females were able to develop new song preferences in adult life. These results are discussed in relation to current views on song preferences and sexual imprinting.

Abstract:

Privateering was a common enterprise in the seventeenth and eighteenth centuries in the waters between the Azores, the Canary Islands and the Iberian Peninsula. Within this ‘oceanic triangle’, both Salé, on the Moroccan coast, and the Canary Islands, in the domains of the Spanish Crown, played an important role. Although privateers from Salé and the Canary Islands evolved in different ways, they were intricately linked through their proximity to one another. This article explores the relationships between the two and the impact of privateering on their respective ports.

Abstract:

Two loci, C and i-C, were previously reported to determine flesh colors between canary yellow and red watermelon (Citrullus lanatus). Recently, lycopene β-cyclase (LCYB) was found as a color determinant gene for canary yellow (C) and a codominant cleaved amplified polymorphic sequence (CAPS) marker was developed to identify canary yellow and red alleles. The inhibitor of canary yellow (i-C), as reported in a previous work, was not detected in our original family derived from a cross between canary yellow and red parents. To identify additional genetic determinants such as i-C, we prepared a new family using ‘Yellow Doll’ (canary yellow) and ‘Sweet Princess’ (red), which was reported to carry the inhibitor gene i-C as parents. A new distinct class of flesh color, pale yellow, was identified in the progeny from the new canary yellow × red cross. The predominant carotenoid in canary yellow and pale yellow phenotypes was neoxanthin, followed by violaxanthin and neochrome; pale yellow contained less total carotenoids, but had more minor carotenoids compared with canary yellow. The chi-square goodness-of-fit test indicated that there are two genes involved in determining flesh color among canary yellow, pale yellow, and red, but the segregation pattern did not fit the pattern as reported for an i-C gene. When the genotype of the family ‘Yellow Doll’ × ‘Sweet Princess’ was analyzed with our LCYB CAPS marker, the flesh color of every individual perfectly cosegregated with the marker. The new pale yellow phenotype also cosegregated with the marker linked to the C allele, indicating that the recessive py phenotype (pale yellow) must carry at least one of the C alleles for expression. Therefore, we propose to designate py for a pale yellow determinant along with C as a canary yellow determinant. A homozygous recessive py gene resulted in pale yellow flesh color in the presence of a dominant C.

Abstract:

Owing to the catastrophic extinction events that occurred following the Holocene arrival of alien species, extant oceanic island biotas are a mixture of recently incorporated alien fauna and remnants of the original fauna. Knowledge of the Late Quaternary pristine island faunas and a reliable chronology of the earliest presence of alien species on each archipelago are critical in understanding the magnitude and tempo of Quaternary island extinctions. Until now, two successive waves of human arrivals have been identified in the North Atlantic Macaronesian archipelagos (Azores, Madeira, Selvagens, Canary and Cape Verde Islands): ‘aboriginal’, which is limited to the Canary Islands around two millennia ago, and ‘colonial’, from the fourteenth century onwards. New surveys in Ponta de São Lourenço (Madeira Island) have allowed us to obtain and date ancient bones of mice. The date obtained (1033 ± 28 BP) documents the earliest evidence for the presence of mice on the island. This date extends the time frame in which the most significant ecological changes occurred on the island. It also suggests that humans could have reached Madeira before 1036 cal AD, around four centuries before Portugal officially took possession of the island.

Full text

Abstract:

ABSTRACT: New information on the domestication of the canary, Serinus canaria, shows that the process by which the wild-type canary was transformed by artificial selection into a pure yellow one occurred earlier than previously thought. Previous studies suggest that selective breeding occurred in Germany, that the first birds with any yellow plumage appeared around 1610, and that the first all yellow birds appeared around 1677. We describe an Italian painting from the 1490s showing completely yellow birds that may be canaries. This suggests selective breeding of canaries may have occurred in Italy before this date. We also report some information from Conrad Gessner who, in 1555, described a specific type of partially yellow canary from Italy. Gessner stated these specially bred birds were transported to Germany, which is where we know selective breeding continued. Paintings in the unpublished encyclopaedia of the German cleric, Marcus zum Lamm, from around 1580 show partially yellow canaries and a crested canary. A painting from around 1657 by the German artist Johann Walter shows what is probably an all yellow canary.

Abstract:

Attempts by anthropologists to account for the peopling of the Canary Islands have led to theories that call for one, two, and even four immigration events. However, most agree the Canary Island Guanche are biologically closest to Berbers from Morocco and Algeria. Genetic contributions from Arabs, Romans, and Carthaginians have also been proposed. An earlier study by Irish using Penrose analysis of odontometric data in samples of Guanche, Shawia and Kabyle Berbers, and Bedouin Arabs supports many of these proposed genetic relationships.The present investigation expands upon this earlier work by adding samples of Carthaginians, Egyptians, and Nubians, and by using tooth size apportionment analysis, a more robust statistical approach for assessing inter-sample differences in the distribution, or allocation, of tooth size in the maxillary and mandibular dental arcades. The analysis yielded three components that account for >80% of the total variance. Cluster analysis and three-dimensional ordination of group component scores provide additional insight into Canary Island/North African relationships. Except for one early Nubian sample, the Guanche exhibit some measure of affinity to all others. However, they are most like Berbers and Carthaginians. These results suggest that Canary Islanders belong to a greater North African gene pool, yet show the closest affinities to Northwest Africans—which corroborates earlier dental and non-dental findings.

Abstract:

AbstractThe banana weevil (BW), Cosmopolites sordidus (Coleoptera: Curculionidae), is one of the most important insect pests of bananas and plantains. The mobility and the origin of BW infestations at the Canary Islands (Tenerife, La Gomera and La Palma) have been analysed using Random Amplified Polymorphic DNA (RAPD) as molecular markers. Populations from Costa Rica, Colombia, Uganda and Madeira were also included for comparison. One hundred and fifteen reproducible bands from eight primers were obtained. The level of polymorphism in the populations from the Canary Islands (40–62%) was in the range of those found in other populations. Nei's genetic distances, pair-wise fixation index (FST) values indicate that the closest populations are Tenerife populations among themselves (Nei's genetic distance=0.054–0.100; FST=0.091–0.157) and Costa Rica and Colombia populations (Nei's genetic distance=0.049; FST=0.113). Our results indicate the existence of BW local biotypes with limited gene flow and affected by genetic drift. These results are compatible with a unique event of colonization at Tenerife; whereas, the outbreaks in La Gomera and La Palma may come from independent introductions. The Madeira population is phylogenetically and geographically closer to the Canary Islands populations, suggesting that it is the most likely source of the insects introduced in the Canary Islands.

Abstract:

Canary rockfish (Sebastes pinniger) have long been an important part of recreational and commercial rockfish fishing from south-east Alaska to southern California, but localised stock abundances have declined considerably. Based on age estimates from otoliths and other structures, lifespan estimates vary from ~20 years to over 80 years. For the purpose of monitoring stocks, age composition is routinely estimated by counting growth zones in otoliths; however, age estimation procedures and lifespan estimates remain largely unvalidated. Typical age validation techniques have limited application for canary rockfish because they are deep-dwelling and may be long-lived. In this study, the unaged otolith of the pair from fish aged at the Department of Fisheries and Oceans Canada was used in one of two age validation techniques: (1) lead-radium dating and (2) bomb radiocarbon (14C) dating. Age estimate accuracy and the validity of age estimation procedures were validated based on the results from each technique. Lead-radium dating proved successful in determining that a minimum estimate of lifespan was 53 years and provided support for age estimation procedures up to ~50–60 years. These findings were further supported by Δ14C data, which indicated that a minimum estimate of lifespan was 44 ± 3 years. Both techniques validate, to differing degrees, age estimation procedures and provide support for inferring that canary rockfish can live more than 80 years.

Abstract:

A revision of the Allium species of the section Molium in the Canary Islands is presented. As part of the phylogenetic revision of the Eurasian representatives of the subgenus Amerallium we found large disagreements in the nomenclature and taxonomy of Allium roseum in the floristic publications on the flora of the Canary Islands. At least four species of the section Molium are mentioned for the flora of the Canary Islands: Allium roseum, A. subvillosum, A. subhirsutum and A. trifoliatum. To learn more about the phylogenetic relationships within a group of closely related species of the section Molium, we used maximum parsimony and Bayesian analyses of combined nuclear (ITS—internal transcribed and ETS—external transcribed spacers of rRNA genes) and three chloroplast (rpl32-trnL and trnL-trnF intergenic spacers and rps16 intron) datasets of 7 taxa. For comparison of the relationships of A. canariense populations between the islands we used the ISSR method. We found that only one species of the section Molium occurs in the Canary Islands—the endemic species Allium canariense, closely related to Allium subvillosum. Independence of this new species has been confirmed by morphological and molecular features. Discussion on phylogeny, origin and geographic distribution is provided.

Abstract:

Abstract. This paper describes a double-station camera set-up in the Canary Islands, called CILBO (Canary Island Long-Baseline Observatory). Image-intensified video cameras – one camera on Tenerife and one on La Palma – monitor the same volume of the atmosphere. They are located in automated roll-off roofs. From the obtained data, the meteoroid trajectory can be computed. A second camera on Tenerife is equipped with an objective grating. For bright meteors (typically 0 mag or brighter), a spectrum is recorded which allows constraining the chemical composition of the meteor. The system is completely automated and sends the obtained data after every observation night to a central FTP server. It has been in operation for about 2 yr and the first scientific results have been produced.

Abstract:

Context. Canary is the multi-object adaptive optics (MOAO) on-sky pathfinder developed in the perspective of multi-object spectrograph on extremely large telescopes (ELTs). In 2013, Canary was operated on-sky at the William Herschel telescope (WHT), using three off-axis natural guide stars (NGS) and four off-axis Rayleigh laser guide stars (LGS), in open-loop, with the on-axis compensated turbulence observed with a H-band imaging camera and a Truth wave-front sensor (TS) for diagnostic purposes. Aims. Our purpose is to establish a reliable and accurate wave-front error breakdown for LGS MOAO. This will enable a comprehensive analysis of Canary on-sky results and provide tools for validating simulations of MOAO systems for ELTs. Methods. To evaluate the MOAO performance, we compared the Canary on-sky results running in MOAO, in single conjugated adaptive optics (SCAO) and in ground layer adaptive optics (GLAO) modes, over a large set of data acquired in 2013. We provide a statistical study of the seeing. We also evaluated the wave-front error breakdown from both analytic computations, one based on a MOAO system modelling and the other on the measurements from the Canary TS. We have focussed especially on the tomographic error and we detail its vertical error decomposition. Results. We show that Canary obtained 30.1%, 21.4% and 17.1% H-band Strehl ratios in SCAO, MOAO and GLAO respectively, for median seeing conditions with 0.66′′ of total seeing including 0.59′′ at the ground. Moreover, we get 99% of correlation over 4500 samples, for any AO modes, between two analytic computations of residual phase variance. Based on these variances, we obtain a reasonable Strehl-ratio (SR) estimation when compared to the measured IR image SR. We evaluate the gain in compensation for the altitude turbulence brought by MOAO when compared to GLAO.

Abstract:

Background: Various health technology assessment (HTA) agencies review new medical devices worldwide, and their recommendations can be useful in guiding clinical decision making. However, different agencies use different processes and methodologies, resulting in variation in recommendations. Objectives: The objectives were to review full HTAs for a new technology for diabetes management, flash glucose monitoring (FGM), with the aim of summarizing similarities/differences in processes, methodologies, and recommendations from the perspective of everyday clinical practice. Methods: A literature review was conducted using online HTA resources. Results: Four full HTAs were identified (Canary Islands, France, Catalunya, and Norway); one issued a conditional recommendation for patients with type 1 diabetes mellitus (T1DM) with controlled glycated hemoglobin (HbA1c) (Spain; Canary Islands), one issued a broader recommendation for patients with T1DM and T2DM (France), and two reported that there was insufficient evidence to support a recommendation (Spain [Catalunya] and Norway). The most comprehensive and stringent of the available HTAs were those in the Canary Islands and Norway, which included systematic literature reviews (SLRs), consultation with patient groups and clinicians, GRADE evidence quality assessments, and full economic models. Comprehensive HTAs either did not recommend FGM (Norway) or restricted the recommendation to a small subpopulation of the overall diabetes population (Canary Islands). Conclusion: HTAs represent a valuable additional resource for clinicians to consider alongside clinical evidence, guidelines, and consensus papers; however, interpreting recommendations requires an understanding of the processes behind these recommendations. In this review, comprehensive HTAs either recommended for a selected subpopulation based on RCT evidence or found insufficient evidence for a recommendation.

Full text

Abstract:

Species of Echium from the Canary Islands represent an adaptive radiation of plants involving evolutionary changes in habitat and life form. Alongside these changes, evolutionary transitions of the sexual system have occurred: approximately one quarter of Echium species from the Canary Islands are dimorphic for gender, paralleling other adaptive radiations of plants on oceanic islands, such as Schiedea in Hawaii. Here, I report on the variation in the frequency of female plants among eight gynodioecious populations representing four species of Echium on the island of Tenerife, and provide preliminary estimates of the seed fertility of females and hermaphrodites, which is an important determinant of the sex ratio for gynodioecious species. Across populations, female frequencies ranged between 6% and 54%, a much wider range than had previously been reported for gynodioecious species of Echium on the Canary Islands. Substantial frequencies of female plants occurred, even though no differences in the seed fertility of females and hermaphrodites were detected.

This study analyzed the association between domestic partner abuse and children's health. The sample consisted of 420 abused women with at least one child, for a total of 406 female children and 504 male children in 420 households. The women reported that one or more of their children had psychological problems in 27.4% of the cases, 13.6% reported physical health problems, and 7.6% reported both psychological and physical health problems. Externalizing problems were reported most frequently (in 11.7% of the children), while internalizing problems were reported in 5.6% of the children. A greater percentage of children with psychological and physical health problems was found in families in which the abusive partner was also abusive toward the children. We found better mental health in children whose mothers did not abuse them. Women whose children did not exhibit physical or mental health problems were younger, had suffered fewer years of abuse, and had fewer children than the women whose children exhibited health problems.

Abstract:

The presence of one or two species of damselflies of the genus Ischnura in the Canary Islands has been a matter of debate in the recent years. The first published records listed I. senegalensis as the only zygopteran inhabiting the archipelago, but this proved to be wrong, and until recently, all specimens of Ischnura captured in the islands were unanimously regarded as belonging to I. saharensis. Recent photographic evidence, however, is compatible with the presence of I. senegalensis. In this study, we give morphological and genetic evidence of the presence of I. senegalensis in the Canary Islands, and we discuss the importance of voucher specimens to correctly identify very similar species.

Abstract:

The ambient noise model CANARY calculates noise coherence and array noise response by treating the noise sources as surface distributions rather than points. This assumption leads to simplification of the propagation, even in range-dependent environments, and by allowing variations in the source density one can represent distant storms or groups of ships. Included is a description of the numerical algorithms used to calculate coherence. Some recently developed analytical solutions for uniform source distributions and uniformly sloping seabed3 are used as test cases for CANARY. Some additional examples demonstrate CANARY's performance in more realistic environments and conditions including wind and shipping sources, and comparisons are made with the noise model RANDI.

Abstract:

AbstractThe osprey, Pandion haliaetus (L), is a cosmopolitan Falconidae that in the Canary Island (Spain) is considered as “endangered” by the Canary Government. No helminthological data of this host are available for this archipelago due its protected status. Forty three Scaphanocephalus expansus were found from the small intestine of one animal. A morphological and morphometric description is given in this work. The species S. expansus can be considered specialists in ospreys, since it has not been found in any other host. It has been found in Europe, Egypt, Asia and North America. According to the references, this is the first report on the helminth fauna of P. haliaetus in the occidental area of Africa.

Agustín Espinosa is one of the most important authors of the Canary Islands. A multifaceted writer, his work as a compiler of island “romances” is little known. In this work we will see what was the status of the Canarian “romances” research at the beginning of the 20th century and we will value the pioneering contribution of the author of Crimen to this field. To do this, we will review what other researchers such as Maximiano Trapero or Diego Catalán have written on the subject and propose a new reading of Espinosa’s research that starts from its context, that is, a reading that derives from a time when literature of the Canary Islands was conc

Abstract:

The study shows results of research on heavy metals concentration in biomass of common reed, hemp and Reed canary grass. The research of common reed was performed during winter period from 2010 until 2012 in 11 natural and artificial water bodies of Latvia. For the harvested biomass in the spring of 2009 and 2010, hemp and reed canary grass samples were investigated.For the collected common reed samples the heavy metal content (Cd, Pb, Cu, Ni, Fe) was established in the biomass. For the hemp and reed canary grass samples, Cd and Pb content were established in the biomass. On the basis of the findings of this research, the suitability of the plant biomass for energy production was analyzed.The heavy metal content in the common reed biomass is suitable for the requirements of solid biofuel. Common reed from all the reed beds of the Latgale (region of Latvia) can be collected in one place and used for the production of fuel. The removal of common reed will help to reduce the heavy metal content in the natural waters and sediment of the reed beds.In the hemp and reed canary grass samples the heavy metals were ascertained periodically. It was found that in some of the research samples they exceeded the MAC for fuel.

Abstract:

Abstract. Meteors are caused by dust particles in the solar system which enter the Earth's atmosphere. Using double-station camera setups, the precise trajectory of these dust particles can be determined. The initial heliocentric orbits of the dust can be derived and valuable information about their distribution, velocities, and composition can be determined. This paper describes a double-station camera setup in the Canary Islands, called CILBO (Canary Island Long-Baseline Observatory). It makes use of automated roll-off roofs to house one camera on Tenerife, one on La Palma, monitoring the same volume of the atmosphere. From the obtained data, the meteoroid trajectory can be computed. A second camera on Tenerife is equipped with an objective grating. For bright meteors, a spectrum is recorded which allows to constrain the chemical composition of the meteor. The system is completely automated and sends the obtained data after every observing night to a central ftp server. It has been in operation for almost two years and the first scientific results are produced.

Abstract:

Phoenix canariensis Chabaud (Canary Palm) is one of the most distinctive landscape elements of several coastal urban centers in Italy. However, over the past few years, international trade has increased the risk of the introduction of Rhynchophorus ferrugineus (Red Palm Weevil) in the country, causing the death of numerous plants. In this work we assessed the damage caused by the insect to Canary Palm in the City of Bari, Apulia Region, furnishing useful information to decision makers and communities for proper preservation measures in favor of this important urban-green resource. The findings shed light on effective and efficient spending strategies of public funds for urban green inside areas affected by the Red Palm Weevil, also based on cost-benefit approaches.

Abstract:

Fire is a powerful force that has shaped forests for thousands of years. It also provokes widespread social concern due to possible economic damage, social effects, impact on homes and properties, and other social effects including fatalities. Regions with seasonal variations in aridity have a fire regime dependent on climate resulting from the role of precipitation and temperature in fire occurrence, implying a synchrony of fire occurrence at regional scale. This spatial and temporal variation of fire regimes regulates the structure, diversity, regeneration dynamics, and nutrient cycle of an area. In the Canary Islands, fires are recurrent in pine forests, although their occurrence in the same area more than once within a 20-year period is rare. The main aim of this work is to reveal, over a 50-year period, fire occurrence and impact on the Canary Islands and how the islands are immersed in a “fire paradox”—a process typical of protected areas, where fire suppression becomes one of the main aims of forest management.

Abstract:

Abstract. Climate evolves following natural variability, and knowledge of these trends is of paramount importance to understand future scenarios in the frame of global change. Obtaining local data is also of importance since climatic anomalies depend on the geographical area. In this sense, the Canary Current is located in one of the major eastern boundary current systems and is mainly driven by the trade winds. The latter promote Ekman transport and give rise to one of the most important upwelling zones of the world on the northwest African coast. Nearly 30 years ago, Bakun (1990) raised a hypothesis contending that coastal upwelling in eastern boundary upwelling systems (EBUSs) might be intensified by global warming due to the enhancement of the trade winds, increasing pressure differences between the ocean and the continent. Using available NCEP/NCAR wind data north of the Canary Islands from 1948 to 2017, we show that trade wind intensity experienced a net decrease of 1 m s−1. Moreover, these winds are strongly influenced, as expected, by large-scale atmospheric patterns such as the North Atlantic Oscillation (NAO). In addition, we found a relationship between the wind pattern and the Atlantic Multidecadal Oscillation (AMO), indicating that the ocean contributes to multidecadal atmospheric variability in this area of the ocean with a considerable lag (>10 years).

Abstract:

Wide-ranging connectivity patterns of common bottlenose dolphins (Tursiops truncatus) are generally poorly known worldwide and more so within the oceanic archipelagos of Macaronesia in the North East (NE) Atlantic. This study aimed to identify long-range movements between the archipelagos of Macaronesia that lie between 500 and 1,500 km apart, and between Madeira archipelago and the Portuguese continental shelf, through the compilation and comparison of bottlenose dolphin’s photo-identification catalogues from different regions: one from Madeira (n = 363 individuals), two from different areas in the Azores (n = 495 and 176), and four from different islands of the Canary Islands (n = 182, 110, 142 and 281), summing up 1791 photographs. An additional comparison was made between the Madeira catalogue and one catalogue from Sagres, on the southwest tip of the Iberian Peninsula (n = 359). Results showed 26 individual matches, mostly between Madeira and the Canary Islands (n = 23), and between Azores and Madeira (n = 3). No matches were found between the Canary Islands and the Azores, nor between Madeira and Sagres. There were no individuals identified in all three archipelagos. The minimum time recorded between sightings in two different archipelagos (≈ 460 km apart) was 62 days. Association patterns revealed that the individuals moving between archipelagos were connected to resident, migrant and transient individuals in Madeira. The higher number of individuals that were re-sighted between Madeira and the Canary Islands can be explained by the relative proximity of these two archipelagos. This study shows the first inter-archipelago movements of bottlenose dolphins in the Macaronesia region, emphasizing the high mobility of this species and supporting the high gene flow described for oceanic dolphins inhabiting the North Atlantic. The dynamics of these long-range movements strongly denotes the need to review marine protected areas established for this species in each archipelago, calling for joint resolutions from three autonomous regions belonging to two EU countries.

Abstract:

Ciguatera Poisoning (CP) is a human food-borne poisoning that has been known since ancient times to be found mainly in tropical and subtropical areas, which occurs when fish or very rarely invertebrates contaminated with ciguatoxins (CTXs) are consumed. The genus of marine benthic dinoflagellates Gambierdiscus produces CTX precursors. The presence of Gambierdiscus species in a region is one indicator of CP risk. The Canary Islands (North Eastern Atlantic Ocean) is an area where CP cases have been reported since 2004. In the present study, samplings for Gambierdiscus cells were conducted in this area during 2016 and 2017. Gambierdiscus cells were isolated and identified as G. australes, G. excentricus, G. caribaeus, and G. belizeanus by molecular analysis. In this study, G. belizeanus is reported for the first time in the Canary Islands. Gambierdiscus isolates were cultured, and the CTX-like toxicity of forty-one strains was evaluated with the neuroblastoma cell-based assay (neuro-2a CBA). G. excentricus exhibited the highest CTX-like toxicity (9.5–2566.7 fg CTX1B equiv. cell−1) followed by G. australes (1.7–452.6.2 fg CTX1B equiv. cell−1). By contrast, the toxicity of G. belizeanus was low (5.6 fg CTX1B equiv. cell−1), and G. caribaeus did not exhibit CTX-like toxicity. In addition, for the G. belizeanus strain, the production of CTXs was evaluated with a colorimetric immunoassay and an electrochemical immunosensor resulting in G. belizeanus producing two types of CTX congeners (CTX1B and CTX3C series congeners) and can contribute to CP in the Canary Islands.

Abstract:

Phoenix canariensis Hort. Ex Chabaud, also known as the Canary Island palm or ornamental palm, is an endemic species of the Canary Islands and has been widely propagated globally. It has become one of the most important and appreciated ornamental plants, especially in the Mediterranean climate. The fruits are edible but used only for feed as they are bitter. Despite its diffusion, not much data on the composition of these fruits and their application as food are available. The aim of this study was to define the chemical characteristics, especially those of the polyphenolic constituents, of red and yellow varieties of Canary palm dates, and to evaluate their use alone or in different mixes in biscuit production. The yellow variety had higher quantities of fiber (36.88% DW (Dry Weight)) and polyphenolic compounds, while the red variety had a high content of sugars, mainly glucose (22.8% DW). Epicatechin is the most important polyphenol of dates (562 μg/g DW). The use of date palm powder on biscuit production resulted in an increase in hardness, polyphenol and fiber content, and antioxidant activity. Sensory analysis showed that the biscuits obtained with a 25/75 mix of red/yellow date powder had the most overall liking.

Abstract:

Based on field work and herbarium studies, a taxonomic revision of the genus Orbilia in the Canary Islands was carried out. Eighteen species of the genus are recognized in the present study. Eight of these are new records for the archipelago (Orbilia cejpii, O. euonymi, O. flavida, O. flavidorosella, O. hesperidea, O. scolecospora, O. vinosa and O. vitalbae). Three of them are here described in detail (O. cejpii, O. flavida and O. vitalbae), because they were not reported again since their first publication. Corrections and clarifications about the identity of four previously reported species (O. alnea, O. auricolor, O. delicatula and O. epipora) are provided, being renamed to O. eucalypti, O. tenuissima, O. xanthostigma, and O. dryadum, respectively, the last one being a new combination for O. alnea var. dryadum. Two species with a rather short original diagnoses reported for the Canary Islands are redescribed in detail (O. corculispora and O. gambelii), and those being endemic for the archipelago are illustrated and briefly discussed (Orbilia adenocarpi, O. asomatica, O. pisciformis and O. succulenticola). A key for the identification of these species, a discussion about closely related taxa, notes on their global distribution, and ecological data are provided.

Abstract:

Herpesviruses (HVs) (Alpha- and Gammaherpesvirinae subfamilies) have been detected in several species of cetaceans with different pathological implications. However, available information on their presence in beaked whales (BWs) is still scarce. In this study, a total of 55 BWs (35 Ziphius cavirostris and 20 animals belonging to the Mesoplodon genus) were analyzed. Samples (n = 294) were obtained from BWs stranded along the coasts of the Canary Islands (1990–2017). Molecular detection of HV was performed by means of a conventional nested PCR based on the DNA polymerase gene. Herpesvirus was detected in 14.45% (8/55) of the analyzed BWs, including 2 positive animals from a previous survey. A percentage positivity of 8.57% was found within the Cuvier’s BW group, while the percentage of positivity rose to 25% within the Mesoplodon genus group (three M. densirostris, one M. europaeus, and one M. bidens). All the obtained sequences from this study belonged to the Alphaherpesvirinae subfamily, from which three are considered novel sequences, all of them within the Mesoplodon genus group. In addition, to our knowledge, this is the first description of HV infection in Gervais’ and Sowerby’s BWs. Three out of eight HV-positive BWs displayed histopathological lesions indicative of active viral replication.

Abstract. Long-term hazard assessment, one of the bastions of risk-mitigation programs, is required for territorial planning and for developing emergency plans. To ensure qualitative and representative results, long-term volcanic hazard assessment requires several sequential steps to be completed, which include the compilation of geological and volcanological information, the characterization of past eruptions, spatial and temporal probabilistic studies, and the simulation of different eruptive scenarios. Despite being a densely populated active volcanic region that receives millions of visitors per year, no systematic hazard assessment has ever been conducted in the Canary Islands. In this paper we focus our attention on El Hierro, the youngest of the Canary Islands and the most recently affected by an eruption. We analyze the past eruptive activity (how), the spatial probability (where) and the temporal probability (when) of an eruption on the island. By studying the past eruptive behavior of the island and assuming that future eruptive patterns will be similar, we aim to identify the most likely volcanic scenarios and corresponding hazards, which include lava flows, pyroclastic fallout and pyroclastic density currents (PDCs). Finally, we estimate their probability of occurrence. The end result is the first total qualitative volcanic hazard map of the island.

Abstract:

Over the last decade, knowledge has significantly increased on the taxonomic identity and distribution of dinoflagellates of the genera Gambierdiscus and Fukuyoa. Additionally, a number of hitherto unknown bioactive metabolites have been described, while the role of these compounds in ciguatera poisoning (CP) remains to be clarified. Ciguatoxins and maitotoxins are very toxic compounds produced by these dinoflagellates and have been described since the 1980s. Ciguatoxins are generally described as the main contributors to this food intoxication. Recent reports of CP in temperate waters of the Canary Islands (Spain) and the Madeira archipelago (Portugal) triggered the need for isolation and cultivation of dinoflagellates from these areas, and their taxonomic and toxicological characterization. Maitotoxins, and specifically maitotoxin-4, has been described as one of the most toxic compounds produced by these dinoflagellates (e.g., G. excentricus) in the Canary Islands. Thus, characterization of toxin profiles of Gambierdiscus species from adjacent regions appears critical. The combination of liquid chromatography coupled to either low- or high-resolution mass spectrometry allowed for characterization of several strains of Gambierdiscus and Fukuyoa from the Mediterranean Sea and the Canary Islands. Maitotoxin-3, two analogues tentatively identified as gambieric acid C and D, a putative gambierone analogue and a putative gambieroxide were detected in all G. australes strains from Menorca and Mallorca (Balearic Islands, Spain) while only maitotoxin-3 was present in an F. paulensis strain of the same region. An unidentified Gambierdiscus species (Gambierdiscus sp.2) from Crete (Greece) showed a different toxin profile, detecting both maitotoxin-3 and gambierone, while the availability of a G. excentricus strain from the Canary Islands (Spain) confirmed the presence of maitotoxin-4 in this species. Overall, this study shows that toxin profiles not only appear to be species-specific but probably also specific to larger geographic regions.

Abstract:

Background and aim: Human studies support the hypothesized contribution of folate deficiency to carcinogenesis and vascular risk. We assess the nutritional folate status and its relationship to folate intake, smoking, alcohol consumption, oral contraceptive use, and multivitamin supplements. Methodology: A representative sample of 601 individuals from 18 to 75 years of age was selected from the participants in the Canary Islands Nutrition Survey. A food frequency questionnaire was administered. Serum and erythrocyte levels of folate were determined using a method of automated ionic capturing. Results: Mean serum and red cell folate were 8.2 ng/mL and 214.3 ng/mL, respectively. Only one individual had serum folate below 3 ng/mL, and 21.7% showed moderate deficits (3–6 ng/mL); 10.7% of the sample had erythrocyte folate levels falling below 140 ng/mL, 61.3% between 140 and 240 ng/mL and the remaining 27.9% above 240 ng/mL. A positive significant association was observed between these two folate measurements, as well as between folate intake and each of these biomarkers (p < 0.001). Tobacco consumption was negatively correlated with folate status (p < 0.001). Alcohol consumption, oral contraceptive, and vitamin supplement use were not associated with serum and red cell folate levels. Conclusions: Even though nutritional folate status can be considered minimally acceptable, it may reflect the low level of fruit and vegetable consumption within the Canary Islands population.

Abstract:

Objective: This work aimed to determine the carriage rate of ESBL-producing Escherichia coli as well as their genetic characteristics in camels from the Canary Islands, Spain. Methods: Fecal samples were recovered from 58 healthy camels from Gran Canaria (n = 32) and Fuerteventura Islands (n = 26) during July 2019. They were seeded on MacConkey (MC) agar no supplemented and supplemented (MC + CTX) with cefotaxime (2 µg/mL). Antimicrobial susceptibility was determined by disk diffusion test (CLSI, 2018). The presence of blaCTX-M, blaSHV, blaTEM,blaCMY-2 and blaOXA-1/48 genes was tested by PCR/sequencing. Furthermore, the mcr-1 (colistin resistance), tetA/tetB (tetracycline resistance), int1 (integrase of class 1 integrons) and stx1,2 genes were analyzed. Phylogenetic groups and sequence types were determined by specific-PCR/sequencing for selected isolates. Results: E. coli was obtained from all the 58 camels in MC media (100%) and in five of them in MC + CTX media (8.6%). Furthermore, 63.8% of E. coli isolates recovered from MC agar were susceptible to all the antibiotics tested. The five E. coli isolates recovered from MC + CTX media were characterized and two of them were ESBL-producers (3.4%). Both ESBL-producer isolates carried the blaCTX-M-15 gene and belonged to the lineages ST3018 (phylogroup A) and ST69 (phylogroup B1). The 3 ESBL-negative isolates recovered from MC-CTX plates were ascribed to phylogroup-B1. Conclusions: Camels can be a source of ESBL-producer bacteria, containing the widespread blaCTX-M-15 gene associated with the lineages ST3018 and ST69.

Abstract:

This article examines the Allied blockade around the Canary Islands as a response to the German cruiser war, since the crossroads of trade routes from the South Atlantic that took place in the Canary Islands allowed the German commerce-raiders to ensure, on the one hand, the encounter with numerous enemy merchant ships, objectives of this economic war and, on the other hand, the aid of the numerous German merchant ships that were in their ports, especially as colliers. The immediate Allied action to block the ports in the Canary Islands took advantage of the undisputed hegemony of Great Britain in the archipelago: the British control of the main infrastructures and port and communication services was added by the joint diplomatic pressure of the British and French, although it was the clear superiority of the British naval forces and the vigilance of their cruisers that most contributed to limiting assistance to German commerce-raiders. Primary and secondary sources, diplomatic and military, both British and Spanish, and also French, shed light on the diplomatic and strategic dimension of a blockade in which the British Admiralty managed to end the threat of German commerce-raiders between August 1914 and March of 1915, and limit the operations of the following German auxiliary cruisers, which briefly operated in the eastern central Atlantic in the early months of 1916.
