Short-tailed albatrosses (Phoebastria albatrus, hereafter "STAL") migrate throughout the North Pacific, overlapping with multiple large scale fisheries. In the Bering Sea, documented bycatch of this species is a focal conservation concern, due to the fact that this species is listed as "endangered" under the U.S. Endangered Species Act. We conducted...
Climate and terrestrial vegetation have had mutual feedbacks for nearly five hundred million years, yet both are now departing from recent historical norms, with uncertain implications for forest ecosystems. This dissertation outlines the current and potential future climate responses of lichen and bryophyte communities in the United States as part...
Introduction: Physical activity (PA) is recommended for all individuals because of the benefits it provides to physical health, mental health, and overall quality of life (QoL). It is also recommended for children with developmental disabilities (DDs), which make up about 15% of all U.S. children ages 3-17 years. Previous studies...
This dissertation describes patterns in epiphytic macrolichen community composition along a nitrogen deposition gradient in the Yosemite region of the Sierra Nevada in California. This region is part of the largest federal air quality Class 1 designated air-shed in the western United States, covering the entire crest of the Sierra...
There are a number of problems associated with urban expansion and as cities continue
to grow the integration of green roofs can help to ease and offset many of them. This study
uses a combination of moss and Sedum as vegetation for experimental green roof sections in
order to test...

Abstract
There are a number of
Large wood (LW) plays an integral role in mountain stream ecosystems, exerting a range of effects on sediment transport, stream morphology, and habitat creation. Human activities, including timber harvesting and clearing of land for agricultural and industrial development, have contributed to a marked decrease in natural sources of LW and...
The dominant theme in the literature indicates an increase of weight bias as the weight of the average Americans rises (e.g., Andreyeva, Puhl, & Brownell, 2008; Fryar, Kruszon-Moran, Gu, & Ogden, 2018). Both weight and gender biases can lead to acts of social injustice. The majority of the studies show...
Introduction: Parents provide an in-depth and unique perspective on their children with developmental disabilities (DDs) experiences and involvement in physical activity. Furthermore, family pets promote physical activity and quality of life in children with DDs. An imitation based physical activity program for children with DD and their family dog took...
Sperm competition is the post-copulatory analog of male-male combat, wherein sperm
from more than one male coincide in a female’s reproductive tract and compete with one
another for fertilization of a limited number of ova. Post-copulatory sexual selection,
such as sperm competition, can be a powerful driving force for the...
