Environmental change poses challenges to many organisms. The resilience of a species to
such change depends on its ability to respond adaptively. Social flexibility is such an …

Male mammals often kill conspecific offspring. The benefits of such infanticide to males, and
its costs to females, probably vary across mammalian social and mating systems. We used …

Parental care is diversely demonstrated across the animal kingdom, such that active
practitioners and repertoires of parental behavior vary dramatically between and within taxa …

Many farm, laboratory, zoo and companion animals experience some form of maternal
deprivation. This is typically via separation from their mothers earlier than would happen in …

Social flexibility, that is, the expression of different types of social systems within one
species, has been reported in several mammalian taxa, including rodents. However …

The authors studied the striped mouse (Rhabdomys pumilio) in the semiarid succulent karoo
of South Africa. Mice forage alone, but they live in groups that share a common nest. Groups …

In most mammalian species, females regularly interact with kin, which is expected to reduce
aggressive competitive behaviour among females. It may thus be difficult to understand why …

The size of an individual's home range is an important feature, influencing reproduction and
survival, but it can vary considerably among both populations and individuals. The factors …

Social groups typically form due to delayed dispersal of adult offspring when no
opportunities for independent breeding exist, or the costs of dispersal are higher than the …

The aim of this study in the biparental rodent Octodon degus was to assess the impact of
paternal deprivation on neuronal and synaptic development in the orbitofrontal cortex, a …
