Impending extinction crisis of the world’s primates: Why primates matter
TLDR
Raising global scientific and public awareness of the plight of the world’s primates and the costs of their loss to ecosystem health and human society is imperative.
Influences of moonlight, ambient temperature, and food availability on the diurnal and nocturnal activity of owl monkeys (Aotus azarai)
TLDR
Examination of changes in activity patterns in owl monkeys of Formosa, Argentina found that the area of study is highly seasonal, and characterized by significant fluctuations in rainfall, temperature, photoperiod, and food availability.
Demographic Changes over Thirty Years in a Red Howler Population in Venezuela
TLDR
The preponderance of unimale groups and female-biased birth sex ratios at low densities and the dispersal of both sexes as adaptations for increasing a population rapidly after a decline are explained.
Cathemerality and Lunar Periodicity of Activity Rhythms in Owl Monkeys of the Argentinian Chaco
Although most South American owl monkeys are mainly nocturnal, Aotus azarai azarai of the Argentinean Chaco regularly shows diurnal activity. In this study we examined the strong influence of…
Estimating Population Density of Amazonian Titi Monkeys (Callicebus discolor) via Playback Point Counts
TLDR
A new method for estimating population density of vocally responsive animals, which is based on playback calls coupled with auditory point transect sampling, is described, which yielded better estimates for red titi monkeys (Callicebus discolor) than traditional line Transect surveys.
Reproductive biology of female titi monkeys (Callicebus moloch) in captivity
TLDR
The analysis of colony records indicated that females whose infant survived through weaning gave birth at intervals remarkably close to one year, while those who lost their offspring showed a significantly shorter interval.
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.
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.
Costs and Benefits of Radio-collaring on the Behavior, Demography, and Conservation of Owl Monkeys (Aotus azarai) in Formosa, Argentina
The benefits to researchers of capturing and collaring free-ranging primates are numerous, but so are the actual and potential costs to the individuals. We aimed to 1) evaluate quantitatively the…
New Perspectives in the Study of Mesoamerican Primates: Distribution, Ecology, Behavior, and Conservation
TLDR
The effects of Forest Fragment Age, Isolation, Size, Habitat Type, and Water Availability on Monkey Density in a Tropical Dry Forest, and Forest Fragmentation and Its Effects on the Feeding Ecology of Black Howlers and Mantled Howler Monkeys are studied.
