Evaluating the influence of land use, drought and reach isolation on the occurrence of freshwater mussel species in the lower Flint River Basin, Georgia (U.S.A.)

Creator:: Shea, Colin P., Peterson, James T., Conroy, Michael J., and Wisniewski, Jason M.
Abstract:: North American freshwater mussels have been subjected to multiple stressors in recent decades that have contributed to declines in the status and distribution of many species. However, considerable uncertainty exists regarding the relative influence of these factors on observed population declines. 2. We used an occupancy modelling approach to quantify...

Using Satellite Imagery to Count Nesting Albatross from Space

Creator:: Dolliver, Jane E.
Abstract:: One fundamental concern in conservation biology is species abundance. For many taxa, however, these data are costly to obtain via direct observation and thus limited in geographic or temporal scope. Very high-resolution satellite imagery provides a means to address these limitations and provide remotely-sensed counts of large, colonial species. We...

Systematics, variation, distribution, and biology of lampreys of the genus Lampetra in Oregon

Creator:: Kan, Ting Tien
Abstract:: Based on the number of velar tentacles and the form of longitudinal lingual laminae found in Lampetra (Entosphenus) t. tridentata and its closely related forms, the taxon Entosphenus should not be considered as a genus as commonly adopted, but, along with the taxa Lethenteron and Lampetra, should be regarded as...

Geomorphic influences on habitat formation, distribution, and development and the classification of upland coastal Oregon streams

Creator:: Hurley, Michael D.
Abstract:: A framework is presented for a more causal explanation and ordering of stream characteristics than traditional means have used. Patterns of stream habitat distribution are related to particular characteristics of the geomorphology of watersheds. Variability in stream characteristics can be explained by the spatial distribution of properties of the watershed...

Interactive influences of wildfire and nonnative species on plant community succession in Hawaii Volcanoes National Park

Creator:: Ainsworth, Alison
Abstract:: The role of fire as a natural disturbance, its interactions with nonnative species and effects of repeated fires in the Hawaiian Islands have received little investigation. We are unsure of the role fire played in shaping forest structure and composition as well as affecting evolutionary processes of the native biota....

Temporal changes in the feeding habits of bullfrogs from three different habitat types in the Willamette Valley, Oregon

Creator:: Bouska, Cassie K.
Abstract:: Bullfrogs were introduced into Oregon in the early 1900s and have become widespread members of many wetland communities. Little is known of their ecology outside their native range, although they may play a role in the current declines observed in native herpetofauna. I analyzed the diets of 401 bullfrogs from...

Impacts of forest-to-agriculture conversion on aboveground and soil carbon and nitrogen stocks along a bioclimatic gradient in Costa Rica

Creator:: Jobse, Judith C.
Abstract:: Tropical forest-to-agriculture conversions contribute to ~20% of contemporary global C emissions. Current global C flux estimates assume C is lost from vegetation and soils over time due to this conversion, and that C stocks in agricultural lands are fairly uniform across the tropics. Global C stock and flux estimates may...

Caspian tern (Hydroprogne caspia) foraging ecology and predation on juvenile salmonids in San Francisco Bay, California

Creator:: Adrean, Lindsay J.
Abstract:: Brooks Island, located in central San Francisco Bay, California, currently supports the largest breeding colony of Caspian terns (Hydroprogne caspia) in the Bay Area, and is one of several proposed relocation sites for some Caspian terns from the world's largest colony in the Columbia River estuary of Oregon. Juvenile salmonids...
