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 ...

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.

Animal Behaviour, 1987
Abstract The hypothesis that acoustic communication mediates spacing between groups of mantled howling monkeys, Alouatta palliata palliata, was tested experimentally in a Costa Rican forest. Previous work showed that reverberation increases with the distance sound propagates within the forest and thus could provide distance cues to monkeys.

Postural and Locomotor Behavior of Alouatta palliata on Various Substrates
Folia Primatologica, 1976A study of the postures and locomotor modes of Alouatta palliata was conducted from mid-June to mid-September 1974 on Barro Colorado Island, Panama Canal Zone. Activities, postures, and locomotor modes were recorded relative to the position of the animals in the trees and to the size and angulatiry of the support structures.

Rates of fermentative digestion in the howler monkey, Alouatta palliata (primates: Ceboidea)
Comparative Biochemistry and Physiology Part A: Physiology, 19831. Caecal material of wild howler monkeys was analyzed by gas chromatography for evidence of fermentation activity and rates of production and absorption of volatile fatty acids. 2. Results showed a high rate of production of acetic acid and lesser production of propionic, butyric and isobutyric acids.

Grooming in the mantled howler monkey,Alouatta palliata Gray
Primates, 1979Dominant individuals groom subordinates in the mantled howler monkey. This relationship is previously unreported for the species and is a characteristic that howler monkeys share with many birds and mammals.
