Reproductive Energetics of Female Mantled Howlers (Alouatta palliata)
International Journal of Primatology, 2017The energetic costs of reproduction have an important influence on the life histories of female primates. At present, however, the interplay of female reproductive state, food availability, and strategies aimed at maintaining energy balance has been described for only a few species, limiting our ability to understand intra- and interspecific variation ...

Forest Fragmentation Modifies Habitat Quality for Alouatta palliata
International Journal of Primatology, 2006Fragmentation reduces habitat area, increases the number of habitat patches, decreases their size, and increases patch isolation. For arboreal mammals such as howlers (Alouatta palliata), canopy modifications from fragmentation processes could also negatively affect habitat quality.

Interactions between Adult Female and Infant Howling Monkeys (Alouatta palliata)
Folia Primatologica, 1973Eight troops containing a total of 151 howler monkeys were studied for 513 h between December 19, 1970, and February 25, 1971. The troops contained 26 mothers with their infants. Mother-infant and other adult female-infant interactions were analyzed for infants from all three age classes.

Foraging Habits of Alouatta palliata mexicana in Three Forest Fragments
Folia Primatologica, 2007The activity patterns and diet of howler monkeys(Alouatta palliata mexicana)were studied in 3 forest fragments in south-eastern Mexico: Playa Escondida (PLA), Agaltepec Island (AGA) and Arroyo Liza (LIZ). Intersite differences offered the opportunity to investigate the foraging adaptations of howler monkeys in response to population and habitat size ...

The Basal Metabolism of Mantled Howler Monkeys (Alouatta palliata)
Journal of Mammalogy, 1979Rates of mass specific oxygen consumption of two resting, postabsorptive howler monkeys at air temperatures of 24 to 26°C were 0.401 ml g−1h−1 (♂, 6.11 kg) and 0.480 ml g−1h−1 (♀, 3.23 kg). These data are about 5% in excess of the values predicted by Kleiber for mammals of similar body mass.

Variations in the mechanical properties of Alouatta palliata molar enamel
American Journal of Physical Anthropology, 2009AbstractTeeth have provided insights into many topics including primate diet, paleobiology, and evolution, due to the fact that they are largely composed of inorganic materials and may remain intact long after an animal is deceased. Previous studies have reported that the mechanical properties, chemistry, and microstructure of human enamel vary with ...

Folia Primatologica, 2022
Abstract Increasing levels of anthropogenic modification, degradation, and fragmentation of arboreal mammal habitats substantially influence wildlife movement and behavior. In Costa Rica, there has been a surge in infrastructure development in the past decade.

Dental topography and molar wear in Alouatta palliata from Costa Rica
American Journal of Physical Anthropology, 2004AbstractPaleoprimatologists depend on relationships between form and function of teeth to reconstruct the diets of fossil species. Most of this work has been limited to studies of unworn teeth. A new approach, dental topographic analysis, allows the characterization and comparison of worn primate teeth.
