Among mammals, the order Primates is exceptional in having a high taxonomic richness which taxa are arboreal, semiterrestrial, or terrestrial. Although habitual terrestriality pervasive among apes and African Asian monkeys (catarrhines), it largely absent of Americas (platyrrhines), as well galagos, lemurs, lorises (strepsirrhines), mostly arboreal. Numerous ecological drivers species-specific factors suggested to set conditions for an evolutionary shift from arboreality terrestriality,...
Several mammal inventories have been reported from the lowland Amazon of Madre de Dios, Peru, but few for Las Piedras River. Here we present a list species Over period seven years (2013–2020), recorded presence species, excluding bats and small rodents, using camera traps opportunistic sightings. Our study area was near Huascar-Las River confluence, 58 km north Dios covering an 22,430 ha. We 60 belonging to orders, 26 families, 53 genera, including novel records...

 Spider monkeys are one of the main seed-dispersal agents in Amazonian ecosystem and therefore help regenerate rainforest. The black-faced black spider monkey (Ateles chamek) is internationally recognized as Endangered, its range limited to Peru, Bolivia Brazil. a difficult genus study little known about their populations wild. Here we present results on demography, habitat use, activity budget preliminary notes ranging pattern diet wild group A. chamek studied floodplain forest...

 Albinism is rarely documented amongst Neotropical mammals, especially in primates, for which only a few cases have been reported. In this paper, we report the first case of albinism wild black-faced black spider monkey (Ateles chamek) found on Las Piedras River south-eastern Peru. The individual, juvenile female, was sighted group primary forest between 2017 and 2020.
