Coalitions and male–male behavior in Alouatta palliata

Primates, 2009
Coalitions influence the establishment and maintenance of social relationships among males in primate species. In this study, we compare the social behavior of males between two groups of Alouatta palliata: a group that was recently taken over by a coalition of two males (Mt), and a group that had a stable composition for at least 9 months (Rh).

Blood Groups of the Mantled Howler Monkey (Alouatta palliata)

Journal of Medical Primatology, 1977
Fifty-two howler monkeys were tested for their human-type A-B-O blood groups. All were group B, as shown by the presence of B and H in their saliva, and anti-A in serum. The B-like agglutinogen of their red cells is common to all New World monkey species tested, and is of different origin and significance than their true A-B-O blood group.

Exploration and play in howler monkeys (Alouatta palliata)

Primates, 1978
Exploration and play were observed in eight troops of howler monkeys (Alouatta palliata) containing 56 young and 95 adults. The behavior patterns of seven age classes are described. There was a clear trend for animals to spend less time in nonsocial exploration with increasing age, and for the frequency of social play to follow an inverted “U” pattern,

Correlates of hormonal modulation in mantled howler monkey males,Alouatta palliata

American Journal of Biological Anthropology, 2021
AbstractObjectivesThe study of hormone modulation may offer important insight into the responses of individuals to environmental challenges. Here we studied C‐peptide, thyroid hormone (T3), glucocorticoid (GC), and testosterone (T) metabolites of mantled howler males to assess: 1) correlations among hormones; 2) individual and temporal variation in ...

Reproductive Energetics of Female Mantled Howlers (Alouatta palliata)

International Journal of Primatology, 2017
The 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, 2006
Fragmentation 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, 1973
Eight 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.
