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

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 …

Abstract The people of New York have long benefited from the state's diversity of
ecosystems, which range from coastal shorelines and wetlands to extensive forests and …

Members of different species often engage in aggressive contests over resources. This
series of aggressive contests between species may result in an interspecific dominance …

Shifts of distributions have been attributed to species tracking their fundamental climate
niches through space. However, several studies have now demonstrated that niche tracking …

Aim Seasonality governs species composition at a given place and time. However, the
effects of climate and land‐use change can vary by season, altering species composition …

Abstract The Red-headed Woodpecker (Melanerpes erythrocephalus) has experienced
strong population declines during the past 3 decades. Using North American Breeding Bird …

Animals inhabiting colder climates have a larger body size (Bergmann's rule) and smaller
body extremities (Allen's rule), which help homeothermic animals to retain heat. Such …

Animal distributions continue to undergo dramatic shifts in response to environmental
change as many ecosystems become altered or transition away from their historic states …

Bergmann's rule is a well‐established, ecogeographical principle that states that body size
varies positively with latitude, reflecting the thermoregulatory benefits of larger bodies as …
