Given its broad geographical distribution, Aotus is a productive genus for comparative studies that evaluate how different ecological factors influence the morphology, behavior, ecology, and demography of closely related species. During 18 mo we collected demographic, ranging, and activity data from owl monkeys (Aotus vociferans) in Yasuní National Park in eastern Ecuador. To collect demographic data, we monitored the trail system several times per week searching for groups. To characterize… 

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).

Activity Patterns, Diet and Home Range of Night Monkeys (Aotus griseimembra and Aotus lemurinus) in Tropical Lowland and Mountain Forests of Central Colombia

TLDR
This research suggests these two nocturnal primates, living in contrasting environments, use similar strategies to cope with the challenges of being active at night in tropical forests.

Density estimates of Panamanian owl monkeys (Aotus zonalis) in three habitat types

TLDR
The presence of A. zonalis in Chagres National Park, albeit at seemingly low abundance, is encouraging and a longer‐term study will be necessary to validate the further abundance estimates gained in this pilot study in order to make conservation policy decisions.

Conservation of Neotropical primates: Ecuador – a case study

Neotropical primates are a highly diverse and ecologically important group that is facing several conservation problems. This review aims to contribute to understanding the nature and extent of these

Surveying Two Endangered Primate Species (Alouatta palliata aequatorialis and Cebus aequatorialis) in the Pacoche Marine and Coastal Wildlife Refuge, West Ecuador

Accurate information on the distribution, demography, and conservation status of endangered populations in threatened habitats are essential to provide the basis for conservation actions and

EXTENSÃO DA DISTRIBUIÇÃO GEOGRÁFICA DE Aotus vociferans (PRIMATES, AOTIDAE)

TLDR
In inventory of primates in the National Forest Tefe, distant about 220 miles west of this enclave, recorded a group A. vociferans, which represents an extension of the geographical distribution of the species and raises the hypothesis that all the interfluves between low Jurua and lower Purus River could be occupied by this taxon.

Estudio preliminar sobre la comunidad de primates en el bosque protector del Oglán Alto. Arajuno-Pastaza

Primates play a crucial ecological role within the ecosystems they inhabit; therefore any effort done in favor of their conservation, will also support the preservation of the other elements of their

Are rainforest owl monkeys cathemeral? Diurnal activity of black-headed owl monkeys, Aotus nigriceps, at Manu Biosphere Reserve, Peru

TLDR
This study observed the diurnal activity of one group of A. nigriceps living in the Manu Biosphere Reserve, Peru over 65 days and indicates that for A.nigriceps the potential costs of shifting to diurnality may outweigh its prospective advantages in this rainforest environment.

Owl monkeys Aotus spp in the wild and in captivity

TLDR
A truly integrated laboratory–field approach that focuses on certain areas that cannot be examined in only one or the other setting (e.g. reproductive biology, communication, energetics) will offer unique opportunities for synergistic interactions between zoo and field research that will have both intellectual and practical benefits.

Density and population structure of owl monkeys (Aotus azarai) in the Argentinean chaco

TLDR
The data suggest that owl monkeys in the seasonal subtropical forests of Formosa live at a density as high as those reported for owl monkey populations observed in tropical forests, and the social groups in the owl monkey population are of comparable size and composition to those characteristic of populations in the tropics.

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.

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.

Social Behavior, Reproductive Strategies, and Population Genetic Structure of Lagothrix poeppigii

TLDR
The genetic results indicate that, as in other atelins, dispersal by females is common, but some male dispersal likely occurs as well, and that direct female-female competition is an important feature of woolly monkey reproductive biology.

Adult Male Replacement in Socially Monogamous Equatorial Saki Monkeys (Pithecia aequatorialis)

TLDR
The replacement of the adult male in one group of sakis in the Ecuadorian Amazon following the death of the initial resident is described and differences in the spatial relationships among group members before and after the replacement are described.

Characteristics and use of sleeping sites in Aotus (Cebidae: Primates) in the Amazon lowlands of Peru

TLDR
In the Amazon lowlands of Peru, Aotus nancymai and A. vociferans were observed to use four different types of sleeping sites: holes in the trunks and branches of dry or senescent trees, complex sites among masses of epiphytes, climbers, and vines, and simple sites among thickets and dense foliage.

Social Monogamy in the Only Nocturnal Haplorhines

TLDR
The two most salient features of owl monkeys are their nocturnal habits and their monogamous social organization, and studies on the cathemeral owl monkeys of the Gran Chaco have begun to offer some insights into their social organization.

Environmental Determinants of Birth Seasonality in Night Monkeys (Aotus azarai) of the Argentinean Chaco

TLDR
Changes in photoperiod and temperature may promote reproductive activity in females that might conceive and begin pregnancy at a time void of high temperatures that could be metabolically challenging, suggesting an environmental control of reproduction.

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.
