Island biogeography has strongly influenced the study of biodiversity because
archipelagos provide natural model systems for investigating patterns of diversity and the
processes that shape ecological communities. I investigated the influence of area and
isolation of islands (n = 32) in the Gulf of California, Mexico on patterns of richness,...
Bats represent the second most diverse group of mammals inhabiting the western slopes of the Cascade Range in southern Washington and Oregon Coast Range. Bat populations may well be sensitive to changes in forest age, structure, or distribution, but their nocturnal habits and high mobility render the study of the...
Vegetation provides food for many insects, and many insects serve as food for bats. We investigated the linkages among these three trophic levels in riparian areas throughout the Oregon Coast Range by examining the influence of vegetation cover, composition, and structure on the activity of nocturnal insects and bats, the...
