Indirect effects of ultraviolet-B radiation on larval amphibians as mediated by food quality and trophic interactions

Creator:: Scheessele, Erin A.
Abstract:: Ultraviolet-B radiation (UVB) is an abiotic stressor in both terrestrial and aquatic systems. The stratospheric ozone layer, depleted due to anthropogenic activities and the cause of elevated UVB at earth's surface over the last four decades, is predicted to recover by 2065. However, UVB levels in aquatic systems may continue...

The ecological and behavioral dynamics of breeding in three sympatric anuran amphibians

Creator:: Olson, Deanna H.
Abstract:: Breeding ecology and behavior were investigated in a field study of three sympatric anuran amphibians in the Oregon Cascade Mountains: the western toad (Bufo boreas), the Cascades frog (Rana cascadae) and the Pacific treefrog (Hyla regilla). A comprehensive study of the western toad mating system was conducted at three populations...

Formation and maintenance of fish assemblages in a high desert Oregon stream

Creator:: Pearsons, Todd N.
Abstract:: Considerable controversy exists about how fish assemblages are organized. I explicitly took fish movement into account while I studied the effects of disturbance, habitat complexity, and predation at different times of the summer to understand the major factors influencing assemblage structure in a high desert Oregon stream. The effects of...

Effects of the invasive Pacific red lionfish Pterois volitans on native Atlantic coral-reef fish communities

Creator:: Albins, Mark A.
Abstract:: Predatory lionfishes (Pterois volitans and P. miles) were introduced to Florida waters during the mid to late 1980s, and eventually established self-sustaining breeding populations in the tropical western Atlantic. These invasive species are now widespread along the southeastern seaboard of the United States, across the Caribbean Sea, and in the...

Harlequin duck demography during winter in Prince William Sound, Alaska : effects of the Exxon Valdez oil spill

Creator:: Esler, Daniel
Abstract:: The 1989 Exxon Valdez oil spill was a major perturbation of nearshore habitats of Prince William Sound, a wintering area for harlequin ducks (Histrionicus histrionicus). This research was designed to evaluate harlequin duck population recovery from the oil spill from 1995 to 1998, using a demographic approach to assess both...

Coral-reef fishes : insights into larval dispersal and invasion ecology

Creator:: Pusack, Timothy J.
Abstract:: Because many coral-reef fishes are observable in situ, are amenable to transplantation, have small home ranges and short generation times, they provide a excellent system to investigate many topics within general ecology, fisheries biology, and conservation biology. The primary goal of this dissertation was to use the coral-reef fishes system...

Infectious diseases of the Felidae : parasite communities from miniature to massive

Creator:: Broughton, Heather M.
Abstract:: Direct anthropogenic stressors have caused drastic declines in wildlife populations over the past two centuries. In the face of these threats, spillover of infectious disease from domestic animals and livestock into wildlife, and novel interactions between parasites and pathogens within wildlife communities, have further suppressed already vulnerable populations. As management...

Amphibian communities and climate change : Where ecological processes meet evolutionary interactions

Creator:: Thurman, Lindsey L.
Abstract:: Forecasts of the impacts of climate change have traditionally focused on individual species and their phenotypes, phenology, or distribution. However, shifts in species distributions and the resulting reorganization of community composition represent an important violation to the assumption of species acting in isolation. Whereas species may respond individualistically to climate...

Factors affecting the dynamics and regulation of coral-reef fish populations

Creator:: Webster, Michael Scott
Abstract:: Ecologists have long questioned why fluctuating populations tend to persist rather than go extinct. Populations that persist indefinitely are regulated by mechanisms that cause demographic density dependence, which works to bound fluctuation above zero. In a series of studies, I have sought to determine the processes and mechanisms that regulate...
