Daily activity patterns, survival, and movements of red tree voles (Arborimus longicaudus) in western Oregon

Creator:: Swingle, James Kerr
Abstract:: We radiocollared a sample of 61 red tree voles in Douglas County, Oregon and monitored their movements to determine daily, seasonal, and sexual differences in behavior and home range attributes. We also collected information on nest attributes, survival, and dispersal of the radiocollared voles. Individual voles were monitored for periods...

Distribution and habitat associations of the northern pygmy-owl in Oregon

Creator:: Sater, Dawn M.
Abstract:: I conducted acoustic lure surveys of northern pygmy-owls (Glaucidium gnoma) on transects that were systematically placed in forested areas throughout the state of Oregon. My objectives were to determine if pygmy-owls were associated with particular forest types, ecoregions, or with large-diameter dominant overstory trees. I also examined temporal variation in...

Habitat selection by Northern Pygmy-Owls on the Olympic Peninsula, WA

Creator:: Giese, Alan R.
Abstract:: Landscape level habitat alterations can have different effects on different species. Species that are more highly specialized for some important aspect of their natural history are expected to be more sensitive to habitat alteration than are those that are generalists. The Northern Pygmy-Owl (Glaucidium gnoma) has been suggested as a...

American marten distributions over a 28 year period : relationships with landscape change in Sagehen Creek Experimental Forest, California, USA

Creator:: Moriarty, Katie M.
Abstract:: The distribution of American martens (Martes americana) within Sagehen Creek Experimental Forest (SCEF), Tahoe National Forest, California has been periodically documented from 1980–1993. This area has been the location of nine marten surveys, each involving a systematic detection/nondetection survey on the same grid. These data are an unprecedented time series...

Age-specific and lifetime reproductive success of known age Northern Spotted Owls on four study areas in Oregon and Washington

Creator:: Loschl, Peter J.
Abstract:: Northern Spotted Owls (Strix occidentalis caurina) are a long-lived forest owl and range-wide declines in their numbers have resulted in the species being listed as threatened under the endangered species act. While many studies have been focused on population trends and reproductive performance of Spotted Owls from different age-classes, none...

Northern goshawk breeding habitat selection within high-elevation forests of southwestern Colorado

Creator:: Ferland, Cheron L.
Abstract:: The northern goshawk (Accipiter gentilis) is a species of concern in the western United States due to its association with mature structural stage forests. I employed a use-versus-availability study design to quantify the vegetative, physiographic, and landscape variables associated with goshawk breeding habitat selection in the San Juan Mountains of...

Estimation of Population Age Structure, Detection Probability, and Density of Red Tree Voles in Oregon

Creator:: Marks-Fife, Chad A.
Abstract:: Red tree voles (Arborimus longicaudus) are a unique species of Arvicoline rodent found in western Oregon and northwest California. Their preferred habitat is mature and old-growth coniferous forest dominated by Douglas-fir (Pseudotsuga menziesii). Tree voles are an important prey item for northern spotted owls and many other predators, but are...

The range expansion of the northern barred owl : an evaluation of the impact on spotted owls

Creator:: Kelly, Elizabeth G.
Abstract:: Since their range expansion into the Pacific Northwest, anecdotal evidence suggests that northern barred owls (Strix varia varia) may be displacing northern spotted owls (Strix occidentalis caurina). My objectives were to characterize barred owl distribution and population increase in Oregon, investigate spotted owl territory performance before and after barred owl...

Competitive interactions and resource partitioning between northern spotted owls and barred owls in western Oregon

Creator:: Wiens, J. David
Abstract:: The federally threatened northern spotted owl (Strix occidentalis caurina) is the focus of intensive conservation efforts that have led to much forested land being reserved as habitat for the owl and associated wildlife species throughout the Pacific Northwest of the United States. Recently, however, a relatively new threat to spotted...

The weather pattern and trends associated with Gulf Stream turbulent heat loss events

Creator:: Loyd, Nicholas
Abstract:: The weather pattern and trends associated with heat flux events (HFEs) over the Gulf Stream (GS) are examined as part of the CLIMODE project. A large portion of GS turbulent heat loss occurs during distinct synoptic scale events with a duration of one to two days. Forty percent (40%) of...
