In this report, we provide information on food plants of the equatorial saki (Pithecia aequatorialis) and its competitors in highland forest of the micro-watershed of the Itaya River, Peruvian Amazonia. From May to November 2009 and from January to April 2010 we followed silently two family groups with the purpose to identify plants whose fruits are part of their diet. During the contacts we had 90 food events in 48 plant species grouped in 24 families. Of these, 36 live in low hill forest and the rest in high terrace forest. The highest diversity of food plants is grouped into seven families that together accounted for 60.4%, among them Moraceae (8 species), Fabaceae (6 species) and Annonaceae (4 species) families. The fruits were mostly eaten in ripe state, being the mesocarp the most appreciated (40%). Among mammals, seven of the competitors were primates, with the main competitor bei...

En este reporte proporcionamos información sobre plantas alimenticias del huapo negro (Pithecia aequatorialis) y sus competidores en bosque de altura de la microcuenca del río Itaya, Amazonía peruana. De mayo a noviembre del 2009 y de enero a abril del 2010 seguimos silenciosamente a dos grupos familiares con el propósito de registrar las plantas cuyos frutos forman parte de su dieta. Durante los contactos tuvimos 90 eventos alimenticios en 48 especies de plantas agrupadas en 24 familias. De ellas, 36 habitan en bosque de colina baja y el resto en bosque de terraza alta. La mayor diversidad de plantas alimenticias está agrupada en siete familias que en conjunto representaron el 60.4%, sobresaliendo entre ellas las familias Moraceae (8 especies), Fabaceae (6 especies) y Annonaceae (4 especies). Los frutos en su mayoría fueron consumidos en estado maduro, siendo el mesocarpio el más...

Lagothrix flavicauda is endemic and lives sympatrically with other primates in the montane forests of Amazonas, San Martín, La Libertad and Huánuco. Detailed information on its density and conservation status, as well as sites with healthy populations is lacking, except for Amazonas where most of the studies were carried out. In order to obtain information on the mentioned aspects, transect censuses were conducted between November and December of 2015, February to May of 2016, and between June and July of 2016 in six survey sites located in the regions of San Martín and Huánuco. As a result of the census, 49 groups belonging to 7 species were sighted, being L. flavicauda the most observed with 14 groups. The largest groups were observed in L. flavicauda (average 13.5±2.2 individuals) and Cebus yuracus (average 12.5±3.6 individuals) and the smallest in Alouatta seniculus (average 3....

The collared peccary (Pecari tajacu) and white-lipped peccary (Tayassu pecari) are very important species as a source of protein and economic income for rural household, and are culturally important in Amazonian Communities. Despite their importance, and due to the scarcity of information on their populations in a large part of the Peruvian Amazon, it is difficult to evaluate the sustainable use as bushmeat and for the export of skins. In this way, this study aims to evaluate populations of P. tajacu and T. pecariin the regions of Loreto and Ucayali by using fixed-width line transects in 33 localities and through interviews to determine the 'cultural consensus' for the abundance of the species in 11 localities. Of a total of 14,220.5 km of 2 linear transects traveled in the study sites, showed that the population density of P. tajacu was 1.24 ind/km 2 being registered in 32 (96.9%) local...
