Cruise ship disturbance to Kittlitz's murrelets (Brachyramphus brevirostris) in Glacier Bay National Park and Preserve, Alaska

Creator:: Marcella, Timothy K.
Abstract:: The Kittlitz's murrelet (Brachyramphus brevirostris), a small pursuit-diving seabird in the family Alcidae, occurs across much of coastal Alaska and parts of the Russian Far East. Glacier Bay National Park, located in Southeast Alaska, is believed to support approximately 37% of the worldwide breeding population of Kittlitz's murrelets during the...

Factors affecting within-season and between-season breeding dispersal of burrowing owls in California

Creator:: Catlin, Daniel H.
Abstract:: Dispersal is integral to our understanding of the life history and population biology of many vertebrates, but difficulties in detecting long distance movements have complicated its study. Moreover, studies of factors affecting dispersal are often unable to determine the relative contributions of variables such as nesting success, mate fidelity, and...

Giant gartersnake spatial ecology in agricultural and constructed wetlands

Creator:: Valcarcel, Patricia M.
Abstract:: The spatial ecology of a species is a vital component of informed management and restoration plans, yet little is known about how animals use restored or constructed habitat. We assessed home ranges, core areas, and habitat selection of the federally threatened Giant Gartersnake (Thamnophis gigas) using rice agricultural habitat and...

The role of food limitation and predation on reproductive success of burrowing owls in southern California

Creator:: Haley, Katherin L
Abstract:: The temporal and spatial variation in reproductive success exhibited by burrowing owls (Athene cunicularia hypugaea) facilitates the testing of mechanisms influencing this parameter. I predicted that food supplementation would increase reproductive success through one of two means: (1) directly, through increasing food availability and decreasing the effects of brood reduction,...

Relationship between plant and butterfly community composition on upland prairies of the Willamette Valley, Oregon

Creator:: York, Melissa M.
Abstract:: Small remnants of 'natural' habitats exist today throughout much of the world. Upland prairies in the Willamette Valley, Oregon have been nearly eliminated by conversion to agriculture and other uses. As a result, very few prairies remain and at least four butterfly species that require this habitat appear to be...

Habitat selection, reproductive success, and site fidelity of burrowing owls in a grassland ecosystem

Creator:: Ronan, Noelle A.
Abstract:: I used a comparative and experimental approach to examine nest habitat selection, reproductive success, and nest site fidelity of burrowing owls (Athene cunicularia) in a large, non-fragmented grassland in southwest California. In 1999, I compared habitat characteristics between nest sites (n = 31) and randomly selected, unoccupied burrows (n =...

Conserving avian diversity in agricultural systems : the role of isolated Oregon white oak legacy trees

Creator:: DeMars, Craig A.
Abstract:: Over one third of the earth’s land surface has been modified to some extent for agricultural purposes. The large global footprint of agriculture, combined with the knowledge that existing reserve networks are likely insufficient for long-term conservation of native biodiversity, has necessitated that agricultural systems contribute to conservation of native...

Effects of diet and crude oil ingestion on growth and biochemistry of captive-reared pigeon guillemots (Cepphus columba)

Creator:: Hovey, Andrew K.
Abstract:: The pigeon guillemot (Cepphus columba) population in Prince William Sound has failed to recover from declines that occurred both before and after the Exxon Valdez Oil Spill (EVOS). Post-spill studies of pigeon guillemot breeding biology have identified three potential factors limiting recovery: (1) predation on eggs and nestlings; (2) declines...

Foraging ecology, colony attendance, and chick provisioning of Caspian terns (Sterna caspia) in the Columbia River Estuary

Creator:: Anderson, Scott K.
Abstract:: This study was designed to enhance understanding of factors influencing foraging distribution, diet composition, and overall reproductive success of Caspian terns (Sterna caspia) nesting on East Sand Island in the Columbia River estuary. This colony of nearly 10,000 breeding pairs is of concern to regional resource managers because Caspian terns...

Assessing and addressing the re-eutrophication of Lake Erie: Central basin hypoxia

Creator:: Scavia, Donald, Allan, J. David, Arend, Kristin K., Brandt, Stephen B., Bartell, Steven, Bosch, Nate S., Briland, Ruth D., Daloğlu, Irem, DePinto, Joseph V., Dolan, David M., Evans, Mary Anne, Farmer, Troy M., Goto, Daisuke, Han, Haejin, Höök, Tomas O., Knight, Roger, Ludsin, Stuart A., Mason, Doran, Michalak, Anna M., Richards, R. Peter, Roberts, James J., Rucinski, Daniel K., Rutherford, Edward, Schwab, David J., Sesterhenn, Timothy M., Zhang, Hongyan, and Zhou, Yuntao
Abstract:: Relieving phosphorus loading is a key management tool for controlling Lake Erie eutrophication. During the 1960s and 1970s, increased phosphorus inputs degraded water quality and reduced central basin hypolimnetic oxygen levels which, in turn, eliminated thermal habitat vital to cold-water organisms and contributed to the extirpation of important benthic macroinvertebrate...
