BACKGROUND Comparing patterns of terrestrial and marine defaunation helps to place
human impacts on marine fauna in context and to navigate toward recovery. Defaunation …

Identifying efficient biodiversity indicators is a key pillar of the global conservation strategy.
Top predators have been proposed as reliable biodiversity signposts, but their role is …

An organism's ability to disperse influences many fundamental processes, from speciation
and geographical range expansion to community assembly. However, the patterns and …

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 …

Montane species worldwide are shifting upslope in response to recent temperature
increases. These upslope shifts are predicted to lead to mountaintop extinctions of species …

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 …

Behavioural plasticity is believed to reduce species vulnerability to extinction, yet global
evidence supporting this hypothesis is lacking. We address this gap by quantifying the …

Climate change affects timing of reproduction in many bird species, but few studies have
investigated its influence on annual reproductive output. Here, we assess changes in the …

The past was a world of giants, with abundant whales in the sea and large animals roaming
the land. However, that world came to an end following massive late-Quaternary megafauna …

Climate change has been associated with both latitudinal and elevational shifts in species'
ranges. The extent, however, to which climate change has driven recent range shifts …
