The origin, distribution, and function of biological diversity are fundamental themes of
ecology and evolutionary biology. Research on birds has played a major role in the history …

One of the most striking patterns in evolutionary biology is that clades may differ greatly in
the number of species they contain. Numerous hypotheses have been put forward to explain …

The extent to which species' ecological and phylogenetic relatedness shape their co‐
occurrence patterns at large spatial scales remains poorly understood. By quantifying …

Despite evidence of declining biosphere integrity, we currently lack understanding of how
the functional diversity associated with changes in abundance among ecological …

Functional traits offer a rich quantitative framework for developing and testing theories in
evolutionary biology, ecology and ecosystem science. However, the potential of functional …

Estimates of global species diversity have varied widely, primarily based on variation in the
numbers derived from different inventory methods of arthropods and other small …

Aim The global species richness patterns of birds and mammals are strongly congruent. This
could reflect similar evolutionary responses to the Earth's history, shared responses to …

Animals have diversified into a bewildering variety of morphological forms exploiting a
complex configuration of trophic niches. Their morphological diversity is widely used as an …

The adaptability of species' climatic niches can influence the dynamics of colonization and
gene flow across climatic gradients, potentially increasing the likelihood of speciation or …

Birds show bewildering diversity in their life histories, mating systems and risk of extinction.
Why do albatrosses delay reproduction for the first 12 years of their life while zebra finches …
