Secondary transfer of adult mantled howlers (Alouatta palliata) on Hacienda La Pacifica, Costa Rica: 1975-2009.
(Primates, 2010-07)
Natal emigration by male and female mantled howlers (Alouatta palliata), and subsequent
immigration into breeding groups, is well documented for the free-ranging population
on Hacienda La Pacifica, Costa Rica, but secondary ...
Dietary choices by four captive slender lorises (Loris tardigradus) when presented with various insect life stages.
(Zoo Biol, 2011-03)
The slender loris (Loris tardigradus) is a rare, nocturnal prosimian found only in
the tropical rainforest of southern India and Sri Lanka. Little is known about their
diet, though it is assumed that insects comprise a majority ...
A comparison of activity patterns for captive Propithecus tattersalli and Propithecus coquereli.
(Zoo Biol, 2016-03)
The activity patterns and social interactions of two species of captive sifaka were
observed during a 2-year period. Allogrooming was not observed in golden-crowned sifaka
and they spent significantly more time resting than ...
Body temperature and thermal environment in a generalized arboreal anthropoid, wild mantled howling monkeys (Alouatta palliata).
(Am J Phys Anthropol, 2014-05)
Free-ranging primates are confronted with the challenge of maintaining an optimal
range of body temperatures within a thermally dynamic environment that changes daily,
seasonally, and annually. While many laboratory studies ...
Fatty acid composition of wild anthropoid primate milks.
(Comp Biochem Physiol B Biochem Mol Biol, 2008-01)
Fatty acids in milk reflect the interplay between species-specific physiological mechanisms
and maternal diet. Anthropoid primates (apes, Old and New World monkeys) vary in patterns
of growth and development and dietary ...
Natal emigration by both sexes in the La Pacifica population of mantled howlers: when do some stay?
(Am J Primatol, 2008-02)
We have reported previously that all male and female mantled howlers emigrate from
natal groups at Hacienda La Pacifica, Costa Rica. In the years since that report,
a small number of juveniles have stayed in the natal group ...
Plasma lipoproteins of free-ranging howling monkeys (Alouatta palliata).
(Comp Biochem Physiol B, 1987)
1. Plasma lipids and lipoproteins of free-ranging howling monkeys from Costa Rica
(Alouatta palliata), aged 5 months to 23 years, were characterized. 2. High density
lipoproteins were lipid-rich, similar to HDL2 of human ...
Dust in the wind: How climate variables and volcanic dust affect rates of tooth wear in Central American howling monkeys.
(Am J Phys Anthropol, 2016-02)
OBJECTIVES: Two factors have been considered important contributors to tooth wear:
dietary abrasives in plant foods themselves and mineral particles adhering to ingested
food. Each factor limits the functional life of teeth. ...
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 ...
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 ...
