Shifts in species distributions are a common ecological response to climate change, and
global temperature rise is often hypothesized as the primary driver. However, the directions …

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

There is mounting evidence of species redistribution as climate warms. Yet, our knowledge
of the coupling between species range shifts and isotherm shifts remains limited. Here, we …

Shorebirds are declining to a greater extent than many other avian taxa around the world. In
North America, shorebirds, along with aerial insectivores and grassland birds, have some of …

Citizen science, the involvement of volunteers in research, has increased the scale of
ecological field studies with continent-wide, centralized monitoring efforts and, more rarely …

Over the past half century, migratory birds in North America have shown divergent
population trends relative to resident species, with the former declining rapidly and the latter …

Increasing temperatures associated with climate change are predicted to cause reductions
in body size, a key determinant of animal physiology and ecology. Using a four‐decade …

Ecology Letters (2011) 14: 677–689 Abstract Although some organisms have moved to
higher elevations and latitudes in response to recent climate change, there is little …

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 …

Recent shifts in phenology in response to climate change are well established but often
poorly understood. Many animals integrate climate change across a spatially and temporally …
