Elevational differences in UV-B response by the long-toed salamander (Ambystoma macrodactylum)

Creator:: Thurman, Lindsey L.
Abstract:: Global amphibian declines have been attributed to numerous and often synergistic causes, such as invasive species, pathogens, and ultraviolet-B (UV-B) radiation. The effects of these stressors are context dependent and can vary with location, species, and populations. As sensitivity to UV-B has shown inconsistencies across amphibian taxa, it can be...

Assessment of fluorinated chemicals (FCs) on developmental toxicity in embryonic zebrafish

Creator:: Duong, Lisa
Abstract:: Fluorinated chemicals (FCs) have been used since the 1950s in many industrial and commercial applications because of their unique properties such as chemical inertness, resistance to heat and their ability to repel water and oils. Concerns regarding potential environmental or human health risk from FCs exposure have emerged due to...

Relative abundance and habitat associations of small mammals in two forest types in southern Oregon

Creator:: Johnston, Aaron N.
Abstract:: I studied small-mammal communities and their response to grazing in mixed-conifer forests and oak woodlands in the Cascade-Siskiyou National Monument in southern Oregon. My objectives were to (1) compare small-mammal communities among forest types and grazing intensities, (2) identify riparian affiliated species, and (3) describe microhabitat associations. Over two years,...

Grazing, nutrients, and marine benthic algae : insights into the drivers and protection of diversity

Creator:: Guerry, Anne D., 1973-
Abstract:: Two of the most powerful ways in which humans have altered ecosystems are by increasing productivity and changing the densities of important consumers. The bottom-up effects of productivity and the top-down effects of consumers have been identified as primary determinants of biological diversity, though the links between them remain unclear....

Stress Physiology in Free-ranging Female African Buffalo (Syncerus caffer) : Environmental Drivers, and Immunological and Infection Consequences

Creator:: Spaan, Johannie M.
Abstract:: Fecal glucocorticoid metabolites (FGMs) are commonly used as indicators of an animal’s stress response in behavioral and eco-physiological studies. Stress in wild animals represents an immediate measure of the physiological response to changes in the environment, and, potentially, a prospective assessment of the animal’s health and well-being. In wild mammals,...

A Comparative Study of Foraging Behavior and Disturbance Regimes in Urban Versus Agricultural Habitats used by Cackling Geese Wintering in the Willamette Valley, Oregon

Creator:: Harrington, Erin R.
Abstract:: The Cackling goose (Branta hutchinsii minima) population has increased from a low of 20,000 in 1984 to the current population of 220,000-300,000 (Stehn 2012, Sanders 2013). As the Cackling goose population began to recover in the late 1990s, the majority of the population relocated from wintering in California to the...

Agricultural impacts on amphibian survival, growth, and distributions

Creator:: Baker, Nick J.
Abstract:: The potential impact of chemical contaminants and conservation practices on amphibians in agricultural landscapes is a key research topic globally. Amphibians represent a common group in many freshwater systems and are currently experiencing worldwide population declines. Global amphibian declines may be attributed to a number of causes, including habitat loss,...

Responses of foothill yellow-legged frog (Rana boylii) larvae to an introduced predator

Creator:: Paoletti, David J.
Abstract:: The consequences of species introductions into non-native habitats are a major cause of concern in the U.S. An introduced species may alter native habitats, cause economic damage, compete with natives for resources or prey on them. Of particular interest are the effects of predation by introduced fishes on native amphibians....

Behavioral adaptations and the minimization of reproductive costs in the male red-sided garter snake, Thamnophis sirtalis parietalis.

Creator:: O'Donnell, Ryan P.
Abstract:: The benefits of reproduction are clear, but there are also costs. Much is known about the costs of reproduction in females, but only recently have male costs been investigated in any depth. These costs of reproduction may be minimized by appropriately modifying behavior, but there has been little research on...

A comparative study of prenatal behavior ontogeny in altricial and precocial murid rodents

Creator:: Robinson, Scott R., 1952-
Abstract:: Using techniques that permit the direct observation of fetuses in vivo, prenatal behavioral development was compared among four species in the rodent family Muridae: the Norway rat (Rattus norvegicus), Mongolian gerbil (Meriones unguiculatus), cotton rat (Sigmodon hispidus), and spiny mouse (Acomys cahirinus). Rattus and Meriones bear altricial offspring, as do...
