In order to explain the variation in primate social systems, socio-ecology has focussed on
the role of ecological factors to explain female associations and relationships and on the …

A deductively obtained model concerning the factors that determine male social
relationships within the framework of primate social organization is discussed in the light of …

Primate males have only recently returned to the center stage of socioecological research.
This review surveys new studies that examine variation in the behavior of adult males and …

Previous analyses of the evolution of primate groups have typically examined the problem in
a different way, focussing on both sexes together rather than on females. The classical …

The aim of this review is to present a coherent explanation of the ultimate causation and the
evolution of primary social systems. The explanation is based on the assumption that social …

This paper discusses the bearing of variations in certain aspects of social structure on the
survival and reproductive success of individuals. Possible factors limiting the female's size …

It is widely assumed that overt behaviour of sexually mature males in primate social groups
is directly linked to paternity of any offspring that are born. This assumption underlies certain …

One of the most obvious changes that has occurred in behavioural biology in recent years is
that it has become conspicuously a problem orientated subject. Moreover, one of the most …

Year–round association between adult males and females is common in primates, even
though internal gestation and lactation predispose males to mate–desertion in the majority …

In the first study conducted on a monogamous neotropical primate, the titi monkey
Callicebus moloch, Mason [1] already touched on the topics and problems to be dealt with in …
