In species with separate sexes, females and males often differ in their morphology,
physiology and behaviour. Such sex‐specific traits are functionally linked to variation in …

Why do some animals mate with one partner rather than many? Here, I investigate factors
related to (i) spatial constraints (habitat limitation, mate availability),(ii) time constraints …

This comprehensive introductory text integrates evolutionary, ecological, and demographic
perspectives with new results from field studies and contemporary noninvasive molecular …

Abstract “Monogamy” and pair bonding have long been of interest to anthropologists and
primatologists. Their study contributes to our knowledge of human evolutionary biology and …

In the last few decades, important advances have been made in the knowledge on the
behavioral ecology of pair-living primates such as owl monkeys (Aotus spp.). With the …

Despite close to three decades of genetic studies that have tried to resolve the precise
phylogenetic position of owl monkeys (genus Aotus) within the platyrrhine radiation, some …

The existence of monogamy in animals is perplexing from an evolutionary perspective. If
individuals:(1) have the opportunity to mate with more than one individual and (2) doing so …

Abstract Knowledge of kin relationships between members of wild animal populations has
broad application in ecology and evolution research by allowing the investigation of …

Natal dispersal, the movement of individuals from their birthplace to new areas in which they
may breed, is an important aspect of life history that influences processes at the level of the …

Biparental care of offspring occurs in diverse mammalian genera and is particularly common
among species with socially monogamous mating systems. Despite numerous well …
