Conveying identity is important for social animals to maintain individually based
relationships. Communication of identity information relies on both signal encoding and …

In social mammals, social integration is generally assumed to improve females' reproductive
success. Most species demonstrating this relationship exhibit complex forms of social bonds …

A central goal of ecology is to understand how environmental variation affects populations.
Long-term studies of marked individuals can quantify the effects of environmental variation …

Individual behavior varies for many reasons, but how early in life are such differences
apparent, and are they under selection? We investigated variation in early-life behavior in a …

When resources are limited, organisms face allocation conflicts. Indeterminate growth
creates a persistent conflict with reproduction, as growth may enhance future reproduction …

When the fitness costs and benefits of sons and daughters differ, offspring sex ratio
manipulation could be an important reproductive tactic. We explored the effects of …

In polygynous species, male reproductive success is predicted to be monopolized by a few
dominant males. This prediction is often not supported, suggesting that ecological and …

Highlights•We found evidence for possible long-term relationships in eastern grey
kangaroos.•Social individuals were more likely to establish potential long-term …

Extreme climatic events such as droughts and floods are expected to become more intense
and severe under climate change, especially in the southern and eastern parts of Australia …

When sons and daughters have different fitness costs and benefits, selection may favor
deviations from an even offspring sex ratio. Most theories on sex ratio manipulation focus on …
