birds. In North America, these habitats or ecosystems include grasslands or prairies …

Unlike resident bird species, the population sizes of migratory species can be influenced by
conditions in more than one part of the world. Changes in the numbers of migrant birds …

This document introduces the viable salmonid population (VSP) concept, identifies VSP

1. Dispersal is of critical ecological and evolutionary importance for several issues of
population biology, particularly population synchrony, colonization and range expansion …

Forest fragmentation, the disruption in the continuity of forest habitat, is hypothesized to be a
major cause of population decline for some species of forest birds because fragmentation …

For birds in urban environments, the configuration of local habitat within the landscape may
be as critical as the composition of the local habitat itself. We examined the relative …

1. Widespread declines in the populations of many British farmland birds have occurred
since the early 1970s. We must understand the causes of these declines tomake …

Outdoor recreation is increasing in intensity and space. Areas previously inaccessible are
now being visited by ever‐growing numbers of people, which increases human–wildlife …

Spatially explicit population models (SEPMs) are often considered the best way to predict
and manage species distributions in spatially heterogeneous landscapes. However, they …

I studied 787 female and 510 male Prothonotary Warblers (Protonotaria citrea) breeding in
southern Illinois, USA, from 1994 to 2000 to test two competing hypotheses that may explain …
