Dominant 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. 

Copulation-interrupting behavior between females within a howler monkey troop

On Barro Colorado Island, Panama, howler monkeys were observed copulating on numerous occasions, however, the copulation was interrupted by a female member of the same troop, suggesting a social mechanism related to high population densities.

Social parasitism in mammals with particular reference to neotropical primates

It is shown that not only do animals but also humans respond in ways that appear to benefit others rather than themselves, which is consistent with the views of Darwin and Dawk.

The functions of status in the mantled howler monkey,Alouatta palliataGray: Intraspecific competition for group membership in a folivorous neotropical primate

It is shown that individual-level selection is sufficient to explain the evolution of this apparently “altruistic” status system and the energetic constraints imposed by a folivorous diet appear to restrict the expression of aggression to “ritualized” forms.

Hand-Holding by Belizean Black Howler Monkeys: Intentional Communication in a Neotropical Primate

The purpose of this brief report is to present preliminary data on hand-holding behavior by Beliz-ean black howler monkeys.

The Effects of Dependent Infants on the Social Behavior of Mantled Howler Monkeys (Alouatta Palliate)

Six weeks of observation on eight groups of wild mantled howler monkeys revealed that the presence of a dependent infant alters the frequency of social interactions between a female with an infant

Embraces and Grooming in Captive Spider Monkeys

Relatively little information is available regarding the role of social grooming and embraces in spider monkeys that live in fission-fusion societies in which individuals are usually split into

Grooming site preferences in female langurs (Presbytis entellus)

The data suggest that the groomee determines the sites being groomed in adult female Hanuman langurs, and close female kin groomed significantly longer, more frequently, and more precisely at inaccessible body parts.

Trade-offs in primate grooming reciprocation: testing behavioural flexibility and correlated evolution

Within-species evidence is found that steeper dominance hierarchies were associated with more grooming being directed up the hierarchy, and that a trade-off occurred between the tendency to groom up the hierarchies and the degree of grooming reciprocation.

Patterns of male–male association in mantled howlers (Alouatta palliata) at La Pacifica, Costa Rica: effects of dominance rank and age

The results provide important data on the nature of male associations within mantled howler groups with linear dominance relationships, and are suggestive of the adaptive value of cooperative relationships.



Capturing and marking howler monkeys for field behavioral studies

Methods for capturing and marking howler monkeys for ecological studies are discussed and the advantages of Ketamine over ether as a holding drug are discussed.

Dominance and reproduction in Baboons (Papio cynocephalus).

This monograph reports on a 14 month study of yellow baboons in the Masai-Amboseli Game Reserve, Kenya, an attempt to determine the relationship between agonistic dominance and reproductive success in male baboons and centered around testing a priority-of-access model of mating behavior.

Studies On the Behavior of Peromyscus Maniculat Us Gambelii and Peromyscus Californicus Parasiticus

An analysis of adult behavior patterns found that P. californicus is more strongly territorial, since paired males and females defend the nest site; however, califORNicus employs a fighting technique involving jumping and avoidance and also exhibits a specific mewing cry which appears to inhibit aggressive behavior of another individual.

The new synthesis?

I shall be addressing three related questions: What are the aims and claims of contemporary sociobiology? How does the enterprise fit into the history of ideas7 And does sociobiology have the
