Many birds and mammals drastically reduce their energy expenditure during times of cold
exposure, food shortage, or drought, by temporarily abandoning euthermia, ie the …

Since the first molecular study providing evidence for mating outside the pair bond in birds
over 30 years ago,> 500 studies have reported rates of extra‐pair paternity (EPP) in> 300 …

Big, time-scaled phylogenies are fundamental to connecting evolutionary processes to
modern biodiversity patterns. Yet inferring reliable phylogenetic trees for thousands of …

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 …

Although reconstruction of the phylogeny of living birds has progressed tremendously in the
last decade, the evolutionary history of Neoaves—a clade that encompasses nearly all living …

Some birds achieve primate-like levels of cognition, even though their brains tend to be
much smaller in absolute size. This poses a fundamental problem in comparative and …

To better determine the history of modern birds, we performed a genome-scale phylogenetic
analysis of 48 species representing all orders of Neoaves using phylogenomic methods …

Current global patterns of biodiversity result from processes that operate over both space
and time and thus require an integrated macroecological and macroevolutionary …

Avian diversification has been influenced by global climate change, plate tectonic
movements, and mass extinction events. However, the impact of these factors on the …

Background Partitioning involves estimating independent models of molecular evolution for
different subsets of sites in a sequence alignment, and has been shown to improve …
