Dust accumulation in the canopy: a potential cause of dental microwear in primates.
(Am J Phys Anthropol, 1995-06)
Dental microwear researchers consider exogenous grit or dust to be an important cause of microscopic wear on primate teeth. No study to date has examined the accumulation of such abrasives on foods eaten by primates in the ...
Stable isotope ratios indicate diet and habitat use in New World monkeys.
(Am J Phys Anthropol, 1997-05)
This paper demonstrates the use of stable isotope ratios of carbon and nitrogen in animal tissue for indicating aspects of species behavioral strategy. We analyzed hair from individuals representing four species of New World ...

Group takeover by a natal male howling monkey (Alouatta palliata) and associated disappearance and injuries of immatures
As part of a long-term study on howling monkey behavior and social dynamics, a known natal male was observed taking over his group from his putative sire. Due to the accidental death of one of the adult males, this natal ...
Relative growth of the limbs and trunk in sifakas: heterochronic, ecological, and functional considerations.
(Am J Phys Anthropol, 1993-12)
Limb, trunk, and body weight measurements were obtained for growth series of Milne-Edwards's diademed sifaka, Propithecus diadema edwardsi, and the golden-crowned sifaka, Propithecus tattersalli. Similar measures were obtained ...
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 ...

(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 ...
