Con el objetivo de evaluar la importancia de los quirópteros frugívoros en el proceso de germinación de semillas, se realizó un estudio en el km 25.3 de la carretera Iquitos-Nauta. Los quirópteros se capturaron usando redes de neblina y las semillas usadas en los experimentos de germinación se extrajeron de las heces de los quirópteros y directamente de los frutos. En total se registraron 23 especies de quirópteros frugívoros que se alimentaron de 35 especies de plantas, las familias más representativas fueron Araceae, Piperaceae y Solanaceae y las especies más consumidas Vismia gracilis y Piper aduncum. Los porcentajes de germinación para las semillas ingeridas fue de 74.24%, significativamente más que en los controles que obtuvieron 51.74% (prueba U de Mann Whitney: p<0.05). Los tiempos promedios de germinación para las semillas ingeridas y los controles fue de 14 días, ...

The Estación Biológica Quebrada Blanco (EBQB) in north-eastern Peruvian Amazonia is a place where research has been conducted since 1984; mainly, on the ecology and behavior of primates, but, later inventories were realized for trees (>10 cm dbh), ferns and birds. The EBQB area is very little disturbed and located in a region of high biodiversity. Here we describe the history of EBQB, summarize the available information on its biodiversity and point out the potential of EBQB for future studies on the biodiversity and ecology of a broad spectrum of organisms.

Los murciélagos son uno de los grupos más diversos de mamíferos en el neotrópico y sus funciones como bioindicadores resaltan su importancia. Es así, que tuvimos el interés de conocer su diversidad, estado de conservación y amenazas en el interfluvio Napo-Putumayo-Amazonas, un sector aún poco explorado de la Amazonía peruana. Para ello sistematizamos estudios de diversas fuentes de información. Encontramos 53 especies de murciélagos, siendo la familia Phyllostomidae y sub familia Stenodermatinae los más representativos. Las especies Artibeus lituratus, Artibeus obscurus, Lophostoma silvicolum, Phyllostomus elongatus, Rhynchonycteris naso y Sturnira tildae se registraron ampliamente en el Putumayo. Los murciélagos frugívoros e insectívoros fueron más diversos que otros grupos de hábitos alimentarios. Se registra a Diclidurus ingens como especie única, en tanto Sturnira l...

Bats are one of the most diverse groups of mammals in the neotropics and their functions as bioindicators underscore their importance. Thus, we studied population diversity, conservation status and threats at the Napo-Putumayo-Amazonas interfluvium, a sector that is still little explored in the Peruvian Amazon. We systematized studies from various sources focusing on the interfluvium. We found 53 species of bats, with the Phyllostomidae family and sub family Stenodermatinae sub family being the most represented. The species Artibeus lituratus, Artibeus obscurus, Lophostoma silvicolum, Phyllostomus elongatus, Rhynchonycteris naso and Sturnira tildae were widely recorded in Putumayo. There was greater diversity of frugivorous and insectivorous bats than bats of other eating habits. Diclidurus ingens is registered as a unique species, while Sturnira ludovici, Artibeus concolor, Cynomops gre...

Bats are one of the most diverse groups of mammals in Peru, and they are also the most feared by the human population, which mostly ignores the qualities and ecological potential governed by their feeding strategies. Therefore, we had the objective of knowing the diversity of these flying mammals in the hill forests of the upper Itaya river basin, in the department of Loreto, Peru. Between 2009 and 2011, we took captures at the understory and middle canopy level in 50 sampling units. The result of the effort of 1800 hours/net 0 registered a species richness ( D) of 47 species, equivalent to 79.6% of the total estimated for this part of the 0 Peruvian Amazon. The D shows significant differences at the stratum level (t = 3.28, p = 0.01), with a greater number of understory species than the middle canopy. In addition, species richness was increased with 17 new records for the area. The frug...

Los primates son fundamentales en la regulación y regeneración de los bosques mediante la dispersión y depredación de semillas, además, son indicadoras del estado de conservación de los ecosistemas y algunas especies son requeridas para consumo de subsistencia y comercialización como carne de monte. Por estas razones, se evaluó el estado poblacional de primates usando el método de transecto lineal ubicados en bosque inundable y tierra firme de la cuenca alta y baja del Putumayo. Recorrimos 838,8 km y se registraron diez especies de primates, nueve fueron de la cuenca alta y ocho de la cuenca baja. Las diez especies se registraron en el bosque inundable y ocho en bosque de tierra firme. La dominancia fue baja entre cuencas y hábitats, mientras entre localidades, Nuevo Belén mostró una alta dominancia debido a la abundancia de Saimiri macrodon. Las densidades poblac...

Primates are fundamental to the regulation and regeneration of forests through the dispersion and predation of seeds. In addition, they act as indicators of ecosystem conservation, while some species are utilized for subsistence and commercialized as bush meat. For these reasons, the population status of primates was estimated in flooded forest and terra firme in the upper and lower Putumayo basin using the linear transect method. Ten primate species were detected over 838.8 kms of transect, nine of which corresponded to the upper basin and eight to the lower basin. Dominance was low among basins and habitats, while among locations; Nuevo Belén showed high dominance due to the abundance of Saimiri macrodon. The highest population densities corresponded to S. macrodon (14.69 ind./km2) and Leontocebus nigricollis nigricollis (7.83 ind./km2), and the lowest to Cebuella pygmaea pygmaea (0....
