Traditional attempts to understand the evolution of human cognition compare humans with
other primates. This research showed that relative brain size covaries with cognitive skills …

Large brains provide adaptive cognitive benefits but require unusually high, near-constant
energy inputs and become fully functional well after their growth is completed …

Cooperative breeding is an extreme form of cooperation that evolved in a range of lineages,
including arthropods, fish, birds, and mammals. Although cooperative breeding in birds is …

Trade‐offs between survival and reproduction are at the core of life‐history theory, and
essential to understanding the evolution of reproductive tactics as well as population …

Agricultural intensification reduces the taxonomic diversity of bird communities, but its
influence on functional diversity has been less studied. Here, we analyze the response of …

In long-lived species, the age-, stage-and/or sex-dependent patterns of survival and
reproduction determine the evolution of life history strategies, the shape of the reproductive …

The age, sex, and sexual maturity of individual animals are key parameters in assessing
wild populations and informing conservation management strategies. These parameters …

The conservation of migratory species poses significant challenges that may be countered
by detailed knowledge about the sites used by migrants throughout the annual cycle. We …

The silver spoon hypothesis proposes that individuals which develop under favorable
conditions will gain fitness benefits throughout their lifetime. Hatching order may create a …

Age‐related variation in reproductive performance in long‐lived iteroparous vertebrate
species is common, with performance being influenced by within‐individual processes, such …
