Aquatic insect adaptations to different flow regimes

Creator:: Yamamuro, Asako Melody
Abstract:: My thesis explored the effects of environmental variability on population dynamics and community composition of aquatic insects. Environmental variability in the form of flow regime in streams can limit the distribution and life-history traits of aquatic insects. I used tributaries to the McKenzie River in Oregon with dramatically different flow...

Thermal ecology of the garter snakes Thamnophis sirtalis concinnus (Hallowell) and Thamnophis ordinoides (Baird & Girard)

Creator:: Stewart, Glenn R.
Abstract:: In recent years, studies dealing with temperature regulation, temperature sensitivity, and physiological responses to temperature in lizards and other reptiles have increased tremendously. It is notable that snakes have been largely ignored in such studies. This no doubt is due to their less direct relationship to ancestral endotherms. However, problems...

Ultraviolet radiation as an environmental stressor of amphibians

Creator:: Bancroft, Betsy A.
Abstract:: My thesis explored the effects of and potential mediating mechanisms for an important environmental stressor, ultraviolet-B (UVB) radiation. UVB radiation has negative effects on organisms in both terrestrial and aquatic systems. I used meta-analysis to quantify the effects of UVB radiation on a diversity of aquatic organisms (Chapter 2). UVB...

A study of behavior in the deer mouse Peromyscus maniculatus rubidus Osgood during its 24-hour cycle of activity in a simulated natural habitat

Creator:: Laban, Cornelis
Abstract:: With a growing emphasis on details of behavior comes an increasing need for knowledge of natural behavior patterns. Studies on the life history of Peromyscus maniculatus have long been available in the literature. More recently, investigators have turned to analyzing the behavior of some of the subspecies of P.m. in...

Cannibalism in larvae of the long-toed salamander, Ambystoma macrodactylum

Creator:: Wildy, Erica Lynn
Abstract:: Predator-prey interactions have historically been studied to explain patterns of organization observed in populations and communities. They have also been important in understanding the evolution of antipredator responses in prey and counterstrategies in predators. Despite the breadth of knowledge that exists for heterospecific interactions, relatively few studies have investigated the...

Aquatic community responses to drought disturbance: experimental manipulations of top predator extinctions and stream drying

Creator:: Boersma, Kate S.
Abstract:: Although it is generally assumed that the intensifying abiotic environment is the primary effect of drought on aquatic organisms, drought-induced top predator extinctions may be an important underlying mechanism. I used manipulative experiments to disentangle the impacts of drying and top predator extinctions on arid-land aquatic invertebrate communities. I then...

Variation in female reproductive success in amphibians

Creator:: Dyal, Leslie A.
Abstract:: My dissertation focuses on the factors that influence variation in female reproductive success in plethodontid salamanders and in toads. Variation in reproductive success fuels evolutionary change. Although, females often have been overlooked in studies of reproductive success due to perceived lower levels of variation when compared to variation in male...

Ecological aspects of kin discriminating behavior with implications of functional value

Creator:: Hokit, D. Grant
Abstract:: To assess the context dependence of kin discriminating behavior, I examined kin-biased aggregation behavior in tadpoles of R. cascadae in different ecological conditions. I manipulated food distribution, predator presence, thermal heterogeneity, and relatedness in a multifactorial mesocosm experiment. All four factors interacted to influence tadpole dispersion. My results suggest that...
