BACKGROUND Climate change impacts have now been documented across every
ecosystem on Earth, despite an average warming of only~ 1° C so far. Here, we describe the …

The current loss of biodiversity has been broadly acknowledged as the main cause of
ecosystem change. To halt this trend, several international agreements have been made …

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 …

The effects of climate change on biodiversity are increasingly well documented, and many
methods have been developed to assess species' vulnerability to climatic changes, both …

In 2002, world leaders committed, through the Convention on Biological Diversity, to achieve
a significant reduction in the rate of biodiversity loss by 2010. We compiled 31 indicators to …

Animal populations have undergone substantial declines in recent decades. These declines
have occurred alongside rapid, human‐driven environmental change, including climate …

Birds are among the most widely studied organisms on earth and represent an important
indicator group for learning about the effects of climate change–particularly in regard to the …

Species are largely predicted to shift poleward as global temperatures increase, with this
fingerprint of climate change being already observed across a range of taxonomic groups …

Around fifteen thousand fieldworkers annually count breeding birds using standardized
protocols in 28 European countries. The observations are collected by using country-specific …

Climate change is an important cause of the irreversible transformation of habitats, of the
rapid extinction of species, and of the dramatic changes in entire communities, especially for …
