Full textLos murciélagos colicortos Carollia brevicauda y C. perspicillata están entre los mamíferos más comunes del Neotrópico y están ampliamente distribuidos. Diversos autores han reportado gran variabilidad entre sus poblaciones; sin embargo, frecuentemente ambas especies son confundidas entre sí en las determinaciones. Diversos estudios se han realizado para comprender sus patrones de distribución y dispersión ya que se encuentran a ambos lados de los Andes. Lo que se pretendes es analizar los patrones biogeográficos de Carollia brevicauda y C. perspicillata, para ello, se propone una caracterización morfológica que permita diferenciarlas, se analiza las poblaciones de ambas especies para probar el rol de barrera de la Depresión de Huancabamba (DH) ubicada entre los Andes de Perú y Ecuador, y finalmente se prueba el rol de los Andes como barrera en la dispersión de ambas especies.

Full textWe report 36 bat species from Parque Nacional Cerros de Amotape, but summary all the previous record the bat species from this place are 42, but with other assessment from near zones the bat species diversity will be 52. The most abundance bat was Artibeus fraterculus 4.94 ind/10-RN, but by habitat, Artibeus jamaicensis was the most abundance in the Pacific Tropical Rainforest (PTR) with 0.97 ind/10-RN, in the ecotono (Pacific Tropical Rainforest-Equatorial Dry Forest) the most abundance specie was Artibeus fraterculus with 6.10 ind/10- RN, and on the Equatorial Dry Forest the most abundance specie was Artibeus fraterculus with 9.25 ind/10-RN. We found significance different in the abundance between the habitat (F = 2.121; df = 72; p = 0.000240) To study the similarity of the bat fauna of the Pacific Tropical forests of Northwestern Peru with other Neotropical lowland rainforests, we reviewed the distribution of 167 species from 20 localities: three in Central America, 12 on the Amazonian basin, and five from the western Andes using a Parsimony Analysis of Endemicity (PAE) and a UPGMA. Both analyses support that bat fauna of the Pacific Tropical forests is more similar to bat fauna from Central America than to the Amazonian basin; in agreement with results based on birds (Cracraft & Prum, 1988), and beetles (Morrone, 2006); supporting as well the Caribean subregion of Morrone (2006). Our results concur with molecular analyses on the genus Artibeus, Glossophaga, Carollia, and Uroderma, that suggest that the Andean cordillera is a great vicariant barrier, and that Central American taxa are more related to Western versant rather than Eastern versant taxa. In northwestern Peru, 42 species were reported, including nine endemics to the Caribean subregion (Lonchophylla hesperia, Artibeus fraterculus, A. jamaicensis, Artibeus ravus, Platyrrhinus matapalensis, Amorphochilus schnablii, Eptesicus innoxius, and Rhogeessa velilla); and 17 species with subspecies different to those from the Amazonian basin (Noctilio leporinus, Chrotopterus auritus, Lophostoma silvicolum, Mimon crenulatum, Phyllostomus hastatus, P. discolor, Desmodus rotundus, Anoura geoffroyi, Glossophaga soricina, Carollia perspicillata, A. lituratus, Chiroderma villosum, Uroderma bilobatum, Lasiurus blossevillii, L. ega, Myotis nigricans, and Molossus molossus). Tumbes, in Perú, represents the southern border of the Caribean subregion.

Full text--- In the Huaylas province there is a great diversity of andean ecosystems in which the Brassicaceae family is one of the most representative plant families. In order to determine and characterize such diversity, a taxonomic and distributional study of the Brassicaceae family was carried out in the Huaylas province, Ancash department. The species were collected and processed following standard methods. The determinations were done using taxonomic keys and through the consult and comparison of the material available in the San Marcos Herbarium (USM). The geographic distribution and the altitudinal ranges were established for each one of the species through the mapping of the collect localities over base maps of Huaylas province. A total of 12 genera and 25 species were found in the Huaylas province, from which 8 are additions to the species of the Brassicaceae family previously reported for the Ancash department like Descurainia depressa, Draba alyssoides and Sisymbrium peruvianum. Of the 25 species presented in the Huaylas province, 18 were found in both the Cordillera Negra and the Cordillera Blanca, 6 only in the Cordillera Negra and 1 only in the Cordillera Blanca. Any of the species reported as endemic for Ancash was found in the Huaylas province. Differences among the altitudinal ranges of the genera and species of the same genera were found. 44% of the species were collected exclusively over 3500 m above the sea level. The number of species reported for Huaylas was increased in near the double.

Full text--- The principal objectives of this work were (i) to represent the geographic distribution of species of section Huicungo for the genus Astrocaryum in Peru and (ii) to characterize the vegetative variability and population structure of Astrocaryum chonta and Astrocaryum javarense in Jenaro Herrera, Requena, Loreto, Peru. For geographic distribution, coordinate data from botanic collections of 12 species was recorded and processed. In Jenaro Herrera, 40 quadrants of 20 x 20 m was studied for each type of forest, floodplain (Estero and Shapajal) and terra firme (Copal and Fierrocaño) forest; quantitative data of vegetative characters and population structure of A. chonta and A. javarense by stage of development (adult plant, juvenile II, juvenile I and seedling) were recorded for each quadrant; also, the structure of each forest was characterized (basal area, vertical profile and light intensity). The geographic distribution of the 12 species in Peruvian Amazon was essentially parapatric, all of them develops below 1000m, except for A. faranae which reach 1650m altitude. The limits between distribution areas were related with geographical, geomorphological and ecological barriers. The vegetative variability comparison of Astrocaryum chonta at floodplain forest showed significant differences in 6 characters for adult plants, 3 for juvenile II, 3 for juvenile I and 2 for seedlings; at population structure level, only the number of adult plants was significantly higher at the Estero floodplain forest. The vegetative variability comparison of Astrocaryum javarense at terrafirme forest showed significant differences in 10 characters for adult plants, 6 for juvenile II, 5 for juvenile I and 3 for seedlings; differences in the number of individuals was not significant. The comparison of vegetative morphology between Astrocaryum chonta and A. javarense showed significant differences (p<0.01; 0.05) in 13 characters for adult plants, 7 for juvenile II, 5 for juvenile I and 1 for seedlings; at level of populations structure, A. chonta in flood plain forest presented significantly higher number of juvenile I and seedlings than A. javarense in terra firme forest. Key words: Arecaceae, Astrocaryum, geographic distribution, morphology variability, structure forest.

Full text--- A revision of the species of the genus Atractus that inhabit Peru was made using external morphological characters (morphometry and meristics), in a total of 14 species. Diagnosis and a key to the species of the genus for Peru are presented and the taxonomic value of their characters is evaluated through a principal component and a discriminant analysis: establishing the length of rostral and loreal scales as crucial characters to the creation of species groups; two species groups are formed: badius and elaps. Cluster analysis were also made in order to support the creation of these species groups. The status of four species is discussed and a possible new species is identified. A distribution map of the Atractus species found in Peru is also shown and the biogeographic hypotheses among these groups are discussed. Apparently, the origin of this genus is the Amazon, and it migrated to the west, only in the species of the badius group.

Full textPeruvian hake (Merluccius gayi peruanus) supports a major fishery in the country. Currently the evaluation and management of this resource assumes the presence of a single stock in the north peruvian sea, however, observations in 1997 suggests the existence of two stocks in the north and south of 6 ° S. The aim of this study is to evaluate using mitochondrial markers the presence of one or two units of hake population, which was amplified for the mitochondrial control region of partial and complete, detected with two techniques: Single Strand Conformational Polymorphism (SSCP) and sequencing, respectively. A high haplotype diversity and low nucleotide diversity, with differentiation and structure genetic low, with the possible presence of two matrilineal lines juxtaposed geographically. Likewise there is evidence that the population underwent a recent population expansion event in the late Pleistocene. In conclusion, the Peruvian hake comprises a single panmictic unit north peruvian sea without the presence of genetic structure in populations, which supports the hypothesis of a single stock, requiring the use of other markers such as microsatellites for analysis to multilocus to have better criteria to support the hypothesis. Key words: Peruvian hake, Merluccius, AND mitochondrial, dynamics of populations.

Full text--- Taxonomic and ecological studies of Aphyllophorales through the altitudinal gradients Corridor Biological Marcapata-Camanti (southeast of Cusco) were studied. The basidiomata of polypore among the altitudinal gradients: 500-1000 msnm, 1000-1500 msnm, 2000-2500 msnm and 2500-3000 msnm was collected intensively. For taxonomic study, keys and descriptions were developed, with information about habit, distribution and comments of Hymenochaetales and Polyporales. Forty six species from 102 specimens collected were indentified. For the first orden, 10 species belonging to Hymenocahtaceae. For the second order, 36 species were identified belonging to the families: Fomitopsidaceae (two species), Ganodermataceae (seven species), Meripilaceae (six species), Meruliaceae (Lamelloporus americanus), Phanerochaetaceae (two species) and Polyporaceae (18 species). In the ecological study, Hymenochaetaceae, Ganodermataceae, Phanerochataceae and Polyporaceae occurred in all altitudinal gradients (500-3000 msnm), as well as in the ecosystems: the Amazon, Pre-Montano and Montano or Cloudy Forest in the CBM-C. Fuscoporia gilva, Ganoderma australe and Polyporus leprieurii as well. The mycodiversity among the gradients tourned out to be variable, both Hymenochaetales and Polyporales. The Amazon Forest (500-1000 msnm) had a higher occurrence of species than Pre-Montane Forest (1000-1500 msnm). For the Montane Forest, 2000-2500 msnm presented higher micodiversity then 2500-3000 msnm. Key words: Andean Amazonian Forest, Hymenochaetales, Polyporales, Taxonomy, Ecology.

Full text--- Chiton cumingsii is a short-distributed species habitant of the intertidal zone fron the cold waters of the Peruvian-Chilean Province (7º-18ºSL), that in high temperatures (19ºC) after the El Niño Event 1997-98, variations in the cycle of the gonadal maturity were observed demanding more metabolic energy following on growth and reproduction, with negative effects in the individuals morphometric and the oocytes citometric. Analysis of variations in the gonadal maturity was done evaluating the gonadal indices and histological features in samples collected from october 1998 to november 1999 in Ancon Bay, while by histochemical analysis was described the morphological development and oocytes-carbohydrates dynamics in oogenesis. The sex ratio was of 4:3 in favor to males without significant differences, except during the spawning stage of april and august. No significant differences between sexes were found in the morphological measures, but higher correlations between length and weight were observed in males. In reproductive analysis, the onset of gametogenesis coincided with increasing sea temperatures in early autumn and decreasing temperatures in spring. Spawnings were in decreasing temperatures in later winter–spring with higher gonadic index values. Histological and histochemical results differentiated five cellular stages in oogenesis. Oogonia, 14_m cells with scarce basophilic cytoplasm are surrounded by few flat follicle cells. In pre-vitellogenetic immature oocytes occurs an increment of mucopolysaccharid acid in cytoplasmic vesicles, while at the end of the immature terminal oocytes (Oc2) begins the vitellogenesis with a reduction of vesicle size, presence of PAS and glycogen-like material spots near them, and the beginning of chorion formation. Dense masses of yolk in primary vitellogenic in mature oocytes (Oc3) completely fill the cytoplasm, decreasing the basophily in secondary vitellogenic mature oocytes (Oc4). Reaching full growth 165_m oocyte size, a chorion differentiated into a series of 38 _m cupules-shape length with distal folds, structured by three (mucopolysaccharid, glycoproteins and lipids) layers. Even no seasonal variations in quantity of reserve material were found, considerable reductions in oocyte size were related to the higher temperatures of 19°C. The presence of glycoproteins in follicle cells is attributed to the chorion formation, while a gradient in mucopolysaccharid and glycogen material during maturity indicates a transfer activity between follicle cells and oocytes.
