The Role of Trees and Thermal Refugia in Greater Sage-Grouse Brood Habitat Selection

Creator:: Dungannon, Tyler D.
Abstract:: It is well documented that greater sage-grouse (Centrocercus urophasianus; hereafter sage-grouse) populations have been in decline throughout their range in the western United States. Currently, sage-grouse occupy approximately 56% of their historic distribution prior to European settlement. Numerous factors have been cited as potential causes for declining productivity and contraction...

Reproductive success of the Hawaiian common gallinule (Gallinula galeata sandvicensis) nesting in taro and managed wetlands on Kaua‘i, Hawai‘i

Creator:: Webber, Bryn M.
Abstract:: The endangered Hawaiian common gallinule (Gallinula chloropus sandvicensis) is an endemic Hawaiian waterbird that occurs only on O‘ahu and Kaua‘i. Hanalei National Wildlife Refuge (NWR) supports the largest population of Hawaiian gallinule on either island and is also one of the highest producers of commercially grown taro in the state....

Effects of Aquatic Resource Subsidies on the Ecology of Terrestrial Top Predators

Creator:: Eriksson, Charlotte E.
Abstract:: Energetic resources transferred between distinct habitats or ecosystems, referred to as allochthonous resources, can greatly subsidize consumers in the recipient habitat, and thus influence food web structure and dynamics. Such subsidies may allow the growth of the consumer population to be decoupled from in situ productivity with effects on consumer...

The Breeding Ecology and Foraging Niche of Aleutian Terns (Onychoprion aleuticus) in the Kodiak Archipelago, Alaska

Creator:: Tengeres, Jill E.
Abstract:: The Aleutian tern (Onychoprion aleuticus) is a species of high conservation concern in Alaska due to large declines at known breeding locations since the 1960s. Due to the small population size and ephemeral behavior of this species on the nesting grounds, there is little basic biological information available and data...

Spatial Variation in Ecosystem Carbon Stocks and Emissions Resulting from Land-use Conversion: Two Studies in Mangrove Forests of the Dominican Republic

Creator:: Giovannoni, Leila R.
Abstract:: Mangrove forests store more organic carbon across ecosystem carbon pools than most other coastal and forested ecosystems, and are subject to high global rates of deforestation. For these reasons, they are recognized as prime candidates for inclusion in climate change mitigation strategies. However, the ecological drivers of regional and micro-scale...

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...

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...

Habitat use, spatial ecology, and stable isotope variability of the Pacific harbor seal (Phoca vitulina richardii) along the Oregon coast

Creator:: Steingass, Sheanna M.
Abstract:: Pacific harbor seals (Phoca vitulina richardii) are one of Oregon’s most common coastal predators, numbering between 10,000 and 12,000 individuals (Brown et al. 2005b). They consume more than 149 species or types of marine prey within the Pacific Northwest, which include a large variety of commercially important fisheries species. Despite...

Movement, dive behavior, and habitat-use of common murres (Uria aalge) in the Northern California Current System under variable ocean conditions

Creator:: Loredo, Stephanie A.
Abstract:: Year-round habitat use of marine predators provides knowledge of important marine areas throughout different life stages. Large-scale, environmental variability, both in space and time, causes changes in the behavior and distribution of marine predators that are important to quantify for conservation. In the Northern California Current System (NCCS), common murres...

Amphibian communities and climate change : Where ecological processes meet evolutionary interactions

Creator:: Thurman, Lindsey L.
Abstract:: Forecasts of the impacts of climate change have traditionally focused on individual species and their phenotypes, phenology, or distribution. However, shifts in species distributions and the resulting reorganization of community composition represent an important violation to the assumption of species acting in isolation. Whereas species may respond individualistically to climate...
