There are multiple observations around the globe showing that in many avian species, both
the timing of migration and breeding have advanced, due to warmer springs. Here, we …

Studies have documented climate change–induced shifts in species distributions but
uncertainties associated with data and methods are typically unexplored. We reviewed 240 …

Declines in European bird populations are reported for decades but the direct effect of major
anthropogenic pressures on such declines remains unquantified. Causal relationships …

A number of studies indicate that tropical arthropods should be particularly vulnerable to
climate warming. If these predictions are realized, climate warming may have a more …

Poleward and upward shifts are the most frequent types of range shifts that have been
reported in response to contemporary climate change. However, the number of reports …

One consequence of climate change is an increasing mismatch between timing of food
requirements and food availability. Such a mismatch is primarily expected in avian long …

Biologists have recently devoted increasing attention to the role of rapid evolution in species'
responses to environmental change. However, it is still unclear what evolutionary responses …

Climate change is predicted to cause changes in species distributions and several studies
report margin range shifts in some species. However, the reported changes rarely concern a …

Global climate change is a major threat to biodiversity. Large-scale analyses have generally
focused on the impacts of climate change on the geographic ranges of species and on …

Climate change is one of the major issues facing natural populations and thus a focus of
recent research has been to predict the responses of organisms to these changes. Models …
