Human Alteration of a Neotropical Landscape Drives Long-term Changes in its Forest Bird Communities

Creator:: Curtis, Jenna R.
Abstract:: Human alteration of natural landscapes leads to biodiversity loss, often from a combination of area effects and fragmentation effects. Smaller habitat patches support fewer species than large ones and incur additional consequences from isolation. Efforts to preempt biodiversity loss from insular habitat fragments are complicated by individualistic species responses and...

The Influence of Wildfire and Invasive Vegetation on Mule Deer

Creator:: Schuyler, Elizabeth
Abstract:: The western United States has experienced large-scale degradation due to land use and land cover changes, invasion of annual grasses, and expansion of woody plants into grass and shrublands and the resultant altered fire regimes. These landscape-scale changes have coincided with declining mule deer (Odocoileus hemionus) populations, making habitat loss...

The Effect of Sill Height on Decay in Air-Seasoning Crossties

Creator:: Rogers, Leon R.
Abstract:: The sustainable use of wood for rail ties requires chemical treatment to increase service life and maintain structural integrity. Treatment can only be applied after lengthy air-seasoning to reduce moisture content in wood, but seasoning leaves ties exposed to attack by decay fungi for up to a year. One factor...

Using a species-centered approach to examine patterns and drivers of avian species richness in the Rogue Basin, Oregon, A 'bird's eye view' : using a species-centered approach to examine patterns and drivers of avian species richness in the Rogue Basin, Oregon

Creator:: Halstead, Katherine E.
Abstract:: The combined effects of habitat loss, degradation, and fragmentation pose a serious threat to Earth's biodiversity, imperiling even relatively common species. 'Habitat' is necessarily a species-specific concept, and investigations of bird diversity relationships and subsequent efforts to prioritize conservation areas, are challenged by the difficulty of estimating complex habitat gradients...

Subalpine revegetation on backcountry campsites near Tuolumne Meadows, Yosemite National Park, California : third year results

Creator:: Moritsch, Barbara J.
Abstract:: The National Park Service initiated a backcountry campsite restoration project in 1987 to restore native vegetation on severely degraded campsites in three subalpine lake basins in Yosemite National Park. Restoration treatments included soil scarification, transplanting, manual seeding and site protection. Eight of the treated campsites were monitored in 1990 to...

The roles of provenance and phylogeny in recruitment, community assembly, and species coexistence in invaded California grasslands

Creator:: Brandt, Angela J.
Abstract:: Biological invasions pose one of the greatest threats to global biodiversity, but many naturalized invaders coexist with the native community. Community ecology theory provides a framework for understanding the mechanisms by which invaders might coexist with native species or exclude them from the community, thus informing management practices to maximize...

Hidden dynamics : community ecology and costs of parasite infection in African buffalo (Syncerus caffer)

Creator:: Henrichs, Brian
Abstract:: Most wild animals are concurrently infected with multiple parasite species for most of their lives. These parasite species assemble into rich and diverse communities, with parasites using host tissues for growth and reproduction as well as evolving strategies to evade the host immune system. The net effect of these ecological...

Epidemic Dynamics of Sudden Oak Death in the Forests of Oregon

Creator:: Carson, Adam
Abstract:: Sudden Oak Death (SOD) is a forest disease caused by the oomycete pathogen Phytophthora ramorum, and infects trees in the Western United States and Europe. This generalist pathogen can infect over 130 species of plants, and causes rapid mortality in tree species in the Fagaceae. Sexual reproduction is thought to...

The use of remote sensing for characterizing forests in wildlife habitat modeling

Creator:: Vogeler, Jody C.
Abstract:: Spatially explicit maps of habitat relationships have proven to be valuable tools for conservation and management applications including evaluating how and which species may be impacted by large scale climate change, ongoing fragmentation of habitat, and local land-use practices. Studies have turned to remote sensing datasets as a way to...

Drivers of arbuscular mycorrhizal fungal community composition in roots : hosts, neighbors, and environment

Creator:: Phillips, Wendy S.
Abstract:: The vast majority of terrestrial plant species live in symbiosis with arbuscular mycorrhizal fungi (AMF). AMF and plants live in complex networks, with roots of individual plants hosting multiple AMF, and single AMF colonizing multiple plants concurrently. Through the exchange of resources, the two partners of this symbiosis can have...
