We ?1 radiotracked 25 adult female fringed myotis (Myotis thysanodes) to day roosts in xeric ponderosa pine (Pinus ponderosa) forests on the east side of the Cascade range in Washington and Oregon from 2001 to 2003.

Saproxylic beetles are highly sensitive to forest management practices that reduce the abundance and variety of deadwood. However, this diverse fauna continues to receive little attention in the southeastern United States even though this region supports some of the most diverse, productive and intensively managed forests in North America. In this replicated three-way factorial experiment, we i...

We conducted winter bird counts from 1998 to 2000 to examine the abundance and habitat association of cavity-nesting bir...
