Methods for Studying the Ecological Physiology of Feeding in Free-Ranging Howlers (Alouatta palliata) at La Pacifica, Costa Rica
(International Journal of Primatology, 2012-06-01)
We lack a general understanding of how primates perform physiologically during feeding to cope with the challenges of their natural environments. We here discuss several methods for studying the ecological physiology of ...
When top-down becomes bottom up: behaviour of hyperdense howler monkeys (Alouatta seniculus) trapped on a 0.6 ha island.
(PLoS One, 2014)
Predators are a ubiquitous presence in most natural environments. Opportunities to contrast the behaviour of a species in the presence and absence of predators are thus rare. Here we report on the behaviour of howler monkey ...
Field methods for capture and measurement of three monkey species in Costa Rica.
(Folia Primatol (Basel), 1991)
A total of 54 free-ranging monkeys were captured and marked in Santa Rosa National Park, Costa Rica, during May 1985, and an additional 17 were captured during March 1986. The animals were darted using a blowpipe or a CO2 ...
Infant-nonmother interactions of free-ranging mantled howlers (Alouatta palliata) in Costa Rica
(International Journal of Primatology, 1998-01-01)
Proximate and ultimate explanations of interactions between infants and nonmothers vary depending upon the relatedness of the interactors. We investigated interactions of infants and nonmothers from a 22-month continuous ...
Darting Primates: Steps Toward Procedural and Reporting Standards
(International Journal of Primatology, 2017-04-21)
© 2017 Springer Science+Business Media New York Darting, a common method of capturing wild primates, poses risks to the individuals that must be appropriately minimized. A recent article in the International Journal ...
Food choice from endemic North Carolina tree species by captive prosimians (Lemur fulvus)
(American Journal of Primatology, 1983-01-01)
Seven captive‐born lemurs (Lemur fulvus) at the Duke University Primate Center were presented with leaves of different maturity from five species of North Carolina trees. The animals demonstrated three distinct behaviors ...
Sexual selection and canine dimorphism in New World monkeys.
(Am J Phys Anthropol, 1988-11)
Social and ecological factors are important in shaping sexual dimorphism in Anthropoidea, but there is also a tendency for body-size dimorphism and canine dimorphism to increase with increased body size (Rensch's rule) (Rensch: ...
A coprological survey of parasites of wild mantled howling monkeys, Alouatta palliata palliata.
(J Wildl Dis, 1990-10)
Fecal samples from 155 mantled howling monkeys (Alouatta palliata palliata) examined at Centro Ecologico La Pacifica, Guanacaste Province, Costa Rica, revealed 75 (48%) had parasitic infections. A sampling of nine howling ...
POISON IN A MONKEYS GARDEN OF EDEN
(NATURAL HISTORY, 1977)
Intake, digestibility, and passage of a commercially designed diet by two Propithecus species.
(Am J Primatol, 1999)
The digestibility and passage of an experimental diet was used to compare the digestive physiology of two Propithecus species: P. verreauxi and P. tattersalli. Though both animals have a similar feeding ecology, the captive ...
