Creator:: Brett, Tiffany A.
Abstract:: I studied nest-site characteristics and habitat relationships for three species ofprimary cavity-nesting birds--hairy woodpecker (Picoides villosus), northern flicker (Colaptes auratus), and red-breasted sapsucker (Sphyrapicus ruber)-- over spatially heterogeneous landscapes in managed forests of the Southern Oregon Cascades during 1995 and 1996. The study was conducted on the Diamond Lake Ranger...

Abstract:: Eight cougars were radio-collared and monitored during 1985 - 1987. Home range size, determined by minimum convex polygons, averaged 153.1 km2 for females, 543.5 km2 for males. Core home range size, determined by harmonic mean analysis, averaged 21.7 km2 for females, 17.9 km2 for males. Home ranges of males and...

Abstract:: This study describes the composition of forest landscapes surrounding northern spotted owl (Strix occidentalis caurina) nests in the central Cascade Mountains of Oregon. I compared forest composition around 126 owl nests in 70 pair territories with forest composition around 119 points drawn randomly from all terrestrial cover-types, and around 104...

Abstract:: We studied the distribution and habitat selection differences between Spanish breed (Corriente and Longhorn mix) and British breed cattle (Angus, Hereford). This study was located on the Zumwalt prairie during the spring and fall and along the Imnaha river for the winter. Each trial ran for two weeks and in...

Creator:: Comfort, Emily Julia, 1974-
Abstract:: There is a perceived trade-off between fire risk reduction and northern spotted owl habitat protection in dry-conifer forests in southwestern Oregon. Management options for balancing this trade-off need to be sought at the landscape level. Applied landscape ecology suggests three important features to consider are (1) patch size and configuration...
