To understand the evolutionary forces that have shaped primate lactation strategies, it is
important to understand the proximate mechanisms of milk synthesis and their ecological …

In many mammals, females form close social bonds with members of their group, usually
between kin. Studies of social bonds and their fitness benefits have not been investigated …

The maternal environment exerts important influences on offspring mass/growth,
metabolism, reproduction, neurobiology, immune function, and behavior among birds …

We evaluate the cost-of-reproduction hypothesis in the burying beetle Nicrophorus orbicollis
and examine how the importance of this trade-off changes as females age (ie, the terminal …

Phenological events of plants and animals are sensitive to climatic processes. Migration is a
life‐history event exhibited by most large herbivores living in seasonal environments, and is …

Mammalian females pay high energetic costs for reproduction, the greatest of which is
imposed by lactation. The synthesis of milk requires, in part, the mobilization of bodily …

In mammals, reproductive success may be positively correlated with both maternal age and
social rank. Because social rank often increases with age, however, the effects of rank and …

Reproductive effort in female ungulates originates from gestation and lactation and has
been studied extensively; however, no comparable studies of reproductive effort in males …

There is increasing evidence that competent handling of social interactions among
conspecifics has positive effects on individual fitness. While individual variation in social …
