The Breeding Ecology and Foraging Niche of Aleutian Terns (Onychoprion aleuticus) in the Kodiak Archipelago, Alaska

Creator:: Tengeres, Jill E.
Abstract:: The Aleutian tern (Onychoprion aleuticus) is a species of high conservation concern in Alaska due to large declines at known breeding locations since the 1960s. Due to the small population size and ephemeral behavior of this species on the nesting grounds, there is little basic biological information available and data...

Atlantic Puffin (Fratercula arctica) Foraging Ecology During Marine Heatwave Conditions

Creator:: Kennerley, William L.
Abstract:: Marine heatwaves (“MHWs”) are discrete periods of anomalously warm ocean conditions that can lead to shifts in the distribution and abundance of marine organisms. Low-trophic level, pelagic forage species are frequently among those affected by MHWs, often resulting in considerable impacts upon their predators. In the North Atlantic Ocean, Atlantic...

Provisioning, growth and survival of Adélie penguin chicks at Cape Crozier, Ross Island, Antarctica

Creator:: Jennings, Scott
Abstract:: Understanding the factors that contribute to or limit reproductive success is a fundamental objective of the field of ecology, providing insight into the ways ecosystems function and facilitating better management of natural resources. Behaviors that benefit offspring often increase costs to parents, and thus parents must adjust their level of...

Addressing Challenges in the Application of Animal Movement Ecology to Aquatic Conservation and Management

Creator:: Ogburn, Matthew B., Mills Flemming, Joanna E., Harrison, Autumn-Lynn, Cooke, Steven J., Torres, Leigh G., and Whoriskey, Frederick G.
Abstract:: The dynamic nature of most environments forces many animals to move to meet their fundamental needs. This is especially true in aquatic environments where shifts in spatial ecology (which are a result of movements) are among the first adaptive responses of animals to changes in ecosystems. Changes in the movement...

Piscivorous colonial waterbirds in the Columbia River estuary : demography, dietary contaminants, and management

Creator:: Suzuki, Yasuko
Abstract:: Caspian terns (Hydroprogne caspia) and double-crested cormorants (Phalacrocorax auritus) nest in large colonies on East Sand Island in the Columbia River estuary, the largest known colonies for the two species in the world. Both species of piscivorous colonial waterbirds have been identified as predators with a significant impact on the...

Redefining the past : essays in diplomatic history in honor of William Appleman Williams

Creator:: Williams, William Appleman and Gardner, Lloyd C., 1934-
Abstract:: The essays in this collection do not cluster about a specific theme, nor do they present a single unified interpretative approach to issues in the history of American foreign policy. Above all, William Appleman Williams is a teacher. And good teachers are disappointed with conformity. No one would ever come...

Ruminal Biodegradation of Heterocyclic Toxic Compounds

Creator:: Tanaree, Dan D.
Abstract:: Cyclic nitramines are a class of compounds that include most of the commonly used explosives today. These are among the most common toxicants released into the environment as a result of human activity, generated on military ranges, battlefields, and production sites. Of these, hexahydro-1,3,5-trinitro-1,3,5- triazine (RDX) is of particular interest,...

California condors in the Pacific Northwest : integrating history, molecular ecology, and spatial modeling for reintroduction planning

Creator:: D'Elia, Jesse
Abstract:: Reintroduction programs are increasingly being used to save animals from extinction and aid in their recovery. The California Condor (Gymnogyps californianus), one of the most endangered birds in the world, is a remarkable example of how reintroduction programs can help rapidly increase a species' population numbers and range following a...
