Seasonal movement, residency, and migration patterns of Wilson's Snipe (Gallinago delicata) across the annual cycle in the Willamette Valley of Oregon.

Creator:: Cline, Brittany B.
Abstract:: Studies of avian movement ecology afford essential insights regarding species' life histories, population dynamics, habitat and resource requirements, and other ecological relationships. While it is widely recognized that events in different stages of the annual cycle have important implications for processes in avian ecology, evolution, and conservation, challenges associated with...

Effects of perturbation on community structure and organization in aquatic microcosms

Creator:: Finger, Susan Everett
Abstract:: Aquatic communities consisting of guppies, amphipods, copepods, snails, nematodes, rotifers, protozoans, euglenoid flagellates, and other microorganisms were established in sixteen laboratory microcosms. Guppies were exploited at four different levels (0 percent, 10 percent, 20 percent, and 40 percent of the population biomass) with four communities at each level of exploitation....

Population demography, resource use, and movement in cooperatively breeding Micronesian Kingfishers

Creator:: Kesler, Dylan C.
Abstract:: Island systems and species are susceptible to extinction because of their small population size and an ecological naiveté from an evolutionary past lacking strong competition and predation. For example, only one-fifth of the world’s bird species occur on islands, yet more than 90% of the avian extinctions witnessed during historic...

Rapid endangered species assessment : a novel approach to improve extinction risk assessments in poorly known species

Creator:: Bianchi, Carlos A.
Abstract:: The number of endangered species is rapidly increasing while paucity of adequate information and resources delays establishment of conservation actions. The IUCN’s listing system is insufficient to determine conservation priorities and many species lack information even to be evaluated (i.e., “data deficient”). Here I proposed and tested the Rapid Endangered...

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...

Nest-site selection in cooperatively breeding Pohnpei Micronesian Kingfishers (Halcyon cinnamomina reichenbachii) : does nest-site abundance limit reproductive opportunities?

Creator:: Kesler, Dylan C.
Abstract:: Despite their inherent importance and utility as ecological examples, island species are among the most endangered and least studied groups. Guam Micronesian Kingfishers (Halcyon cinnamomina cinnamomina) exemplify the plight of insular biota as a critically endangered and understudied island bird that went extinct in the wild before they could be...

Incubation patterns, parental roles, and nest survival of black oystercatchers (Haematopus bachmani) : influences of environmental processes and potential disturbance stimuli

Creator:: Spiegel, Caleb S.
Abstract:: Shorebirds display great variation in mating systems and breed in dynamic environments that are increasingly subject to human threats worldwide. In order to adequately assess productivity and demography of shorebird populations, it is important to understand factors that influence patterns of parental care and reproductive success. The Black Oystercatcher (Haematopus...

Population Ecology of the Mariana Swiftlet (Aerodramus bartschi) on O'ahu, Hawaiian Islands

Creator:: Johnson, Nathan Christopher
Abstract:: The Mariana Swiftlet (Aerodramus bartschi) (Aves: Apodidae) is endemic to the Mariana Islands, where it currently occurs on Saipan, Aguiguan, and Guam. An introduced population of Mariana Swiftlets is also present on O'ahu in the Hawaiian Islands. Sparing interference with the endangered population in the Marianas, the introduced, surrogate population...

Phylogeography and population structure of least terns (Sterna antillarum)

Creator:: Draheim, Hope M.
Abstract:: Historically, least terns (Sterna antillarum) were one of the most common tern species in North America. However, population declines have resulted from direct and indirect anthropogenic pressures on their breeding and foraging habitat. Three subspecies of least terns have been described within the United States: California least tern (S. a....

Seasonal movement, home range, and abundance of the Mariana Common Moorhen (Gallinula chloropus guami) on Guam and the northern Mariana Islands

Creator:: Takano, Leilani L.
Abstract:: The endemic avifauna of Guam and the Mariana Islands represent a unique assemblage of bird species found nowhere else in the world and thus, are of considerable biological and conservation importance. Unfortunately, most of these species are understudied and exist in precariously low populations. The endangered Mariana Common Moorhen (Gallinula...
