In the Amazon lowlands of Peru, Aotus nancymai and A. vociferans were observed to use four different types of sleeping sites: (1) holes in the trunks and branches of dry or senescent trees; (2) concavities in polyaxial branching nodes of trees protected by dense entanglements of creepers, climbing plants, vines, and masses of diverse epiphytes; (3) complex sites among masses of epiphytes, climbers, and vines; and (4) simple sites among thickets and dense foliage. Each type is described. There… 

Sharing of sleeping sites betweenAotus vociferans with other mammals in the Peruvian Amazon

TLDR
This study is the first report of cooccupation within the genera Aotus, and one sleeping site was observed in a small concavity of the foliar sheath on aMauritia flexuosa palm.

Sleeping sites and lodge trees of the night monkey (Aotus azarae) in Bolivia

TLDR
The structure of sleeping-site compared lodge trees to nonlodge trees, and the frequency of their use were characterized; the distribution of lodge trees appeared to be related to access to food and activities around the sleeping site could berelated to marking behavior.

Supplemental notes on population parameters of northeastern Peruvian night monkeys, genus Aotus (Cebidae)

Family groups of Aotus nancymae and A. vociferans, captured and observed in lowland flooded forest of northeastern Peru, are compared. The groups differ in size, composition, social organization, sex

Population Density of Aotus cf. lemurinus (Primates: Aotidae) in a Subandean Forest Patch on the Eastern Slopes of the Western Andes, Region of Dapa, Yumbo, Valle del Cauca, Colombia

Little is known of the demography of night monkeys, Aotus. The few studies that have been conducted in specific sites of the Amazon region do not allow for landscape-level inferences, and many of

Types and forms of sleeping dens of pacas (Cuniculus paca) in the upper

TLDR
Results indicate that this rodent uses holes in the ground or in fallen trees as sleeping dens as well as a greater concentration of sleeping dens in temporary flooded gallery forest.

Habitat use, fruit consumption, and population density of the black-headed night monkey, Aotus nigriceps, in Southeastern Peru

TLDR
The results suggest that the black-headed night monkey can survive and even thrive in secondary forest, feeding extensively on pioneer species, occupying a range of forest types, all while living in proximity to people (<1km).

Resting sites of opossums (Didelphimorphia, Didelphidae) in Atlantic Forest fragments

Abstract We report the type and pattern of use of resting sites used by 14 radio-tracked opossums. Philander frenatus rested in natural structures but also on spherical structures of dry leaves,

Population densities and geographic distribution of night monkeys (Aotus nancymai and Aotus vociferans) (cebidae: Primates) in Northeastern Peru

TLDR
Population densities of two species of night (or owl) monkeys (Aotus nancymai and Aotus vociferans) were estimated using transect census methods, which confirmed that the two species are nowhere sympatric.

Bassaricyon gabbii (Carnivora: Procyonidae)

TLDR
B. gabbii is a procyonid that occurs in Central America from Nicaragua through Panama, and in South America has been documented in Colombia, Ecuador, Peru, and Venezuela and is included in Appendix III of the Convention on International Trade in Endangered Species of Wild Flora and Fauna.

Cebus nigritus impact the seedling assemblage below their main sleeping sites

TLDR
The dominance of plant species dispersed by these primates in the seedling assemblages below sleeping trees confirm the strong weight of C. nigritus and their potential influence in the dynamics of the seedlings populations in the forest.

TLDR
One group of 2 adults and 2 juveniles utilized the same lodge area in the center of a home range of 3.1 ha for the duration of the study, and utilized eleven fruit trees of nine different species during the 9 weeks.

The nine allopatric species of Aotus recognized represent two natural groups distinguished by karyotype, color, and pelage patterns, and a key to the species and subspecies gives the diagnostic characters of each.

Two new karyotypes in the Peruvian owl monkey (Aotus trivirgatus)

TLDR
The chromosome complement of a “phenotype‐B” Aotus population from Peru was examined and it was indicated that the chromosome number polymorphism in these Peruvian owl monkeys resulted from a single fusion or fission event involving a single metacentric and two acrocentric chromosome pairs.
