Bird-vegetation associations are a base for bird conservation and management, as well as for predictions of the effects of resource management and climate change on wildlife populations. A recent shift in forest management priorities from timber production to native species' habitat conservation on federal lands has emphasized the need to...

Bird-vegetation associations are a base for bird
This thesis examines depictions of medievalism in three central texts: Sir Walter Scott's Ivanhoe, Mark Twain's A Connecticut Yankee in King Arthur's Court, and George R.R. Martin's A Game of Thrones. Each of these texts provides an entry point for exploring the ways in which English and American writers have...
Two experiments were conducted to evaluate the use of wet brewers' grain (WBG) alone and with straw so it can be used as part of the sole ration for ruminants. In Exp. 1, WBG was ensued alone and was mixed with one of two straws, wheat or tall fescue grass...
Future scenarios of global climate change rely on large-scale climate envelope models that do not account for local climatic conditions to which organisms most closely respond. Shifts in species distributions and phenology driven by climate change are well-documented, yet we lack a strong understanding of how climate change will influence...
Little is known on the importance of riparian areas to birds near small headwater streams in mesic forests. Progress towards understanding limiting factors that affect bird populations has been difficult because of lack of information beyond the breeding period. I compared bird assemblages between headwater riparian and upland areas throughout...
Pollination is a critical ecosystem function for sustaining biodiversity. However, pollinators and the services they provide are threatened by landscape-altering anthropogenic activities across the globe. Habitat loss and fragmentation, introduction of invasive species, chemical use, and urbanization have been shown to impact pollination. Pollinator foraging behavior is thought to be...
Altered skeletal muscle fat metabolism is linked to changes in skeletal muscle insulin sensitivity. Whereby the accumulation of bioactive signaling lipids (i.e., diacylglycerols and ceramides) within skeletal muscle are negatively associated with insulin sensitivity and the exercise-induced changes to fatty acid trafficking are related to improved skeletal muscle insulin action....
Anthropogenic land-cover change and climate change are the major drivers of the steep loss of avian biodiversity in past decades. Loss of avian biodiversity is predicted to result in the reduction of ecosystem services and ecological functions. Identifying avian population changes and the drivers of these trajectories is essential for...
Skeletal muscle mitochondria are highly plastic organelles, integral to whole-body health. High-fat diet (HFD) and exercise remodel the skeletal muscle mitochondria. Whereby, altered skeletal muscle mitochondrial function is linked to decreased skeletal muscle insulin sensitivity which can be reversed by exercise. However, the mechanisms that contribute to skeletal muscle remodeling...
A growing body of work reveals that animal-mediated pollination is negatively affected by anthropogenic disturbance. Landscape-scale disturbance results in two often inter-related processes: (1) habitat loss, and (2) disruptions of habitat configuration (i.e. fragmentation). Understanding the relative effects of such processes is critical in designing effective management strategies to limit...
