Are Bird Habitat Associations Consistent Across Space and Time?

Creator:: Rousseau, Josée S.
Abstract:: The concept of the fundamental niche is frequently used in ecology to define the set of environmental conditions needed by a species to survive and reproduce (Hutchinson 1957). In contrast, the realized niche constitutes the locations where a species actually occurred, which is a function of both the environmental (abiotic)...

Ecology and Distribution of Blue Whales in New Zealand Across Spatial and Temporal Scales

Creator:: Barlow, Dawn R.
Abstract:: The distribution of mobile marine predators often reflects underlying dynamic ecological processes. The geographical focus of this PhD is the South Taranaki Bight (STB) of New Zealand, where wind-driven coastal upwelling generates productivity and prey to support a blue whale foraging ground. The STB is also New Zealand’s most industrial...

Structure and Function of Foliar Fungal Communities of Populus trichocarpa Across its Native Range, Pacific Northwest, USA

Creator:: Barge, Edward G.
Abstract:: Foliar fungi – pathogens, endophytes, epiphytes – form taxonomically diverse communities that affect plant health and productivity. The composition of foliar fungal communities is variable at spatial scales both small (e.g., individual plants) and large (e.g., continents). However, few studies have focused on how environmental factors and host plant traits...

California condors in the Pacific Northwest : integrating history, molecular ecology, and spatial modeling for reintroduction planning

Creator:: D'Elia, Jesse
Abstract:: Reintroduction programs are increasingly being used to save animals from extinction and aid in their recovery. The California Condor (Gymnogyps californianus), one of the most endangered birds in the world, is a remarkable example of how reintroduction programs can help rapidly increase a species' population numbers and range following a...

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...

Farmers' risk attitudes in the eastern high plateau region of Algeria : an application of the experimental approach

Creator:: Belaid, Abderrezak
Abstract:: Farmers in the high plateau region of Algeria are assumed to exhibit risk averse behavior, particularly, due to highly variable weather conditions inducing income instability over time. This in turn directly affects their production behavior. The Eastern High Plateau (Setif) is not a homogeneous region. In the El-Eulma daira, for...

Effects of Medicinal Herbs on Contraction Rate of Cultured Cardiomyocyte. Possible Mechanisms Involved in the Chronotropic Effects of Hawthorn and Berberine in Neonatal Murine Cardiomyocyte

Creator:: Salehi, Satin
Abstract:: Herbs have been used for many centuries in diverse civilizations for the treatment of heart disease. Only a few natural supplements claim to have direct cardiovascular actions including hawthorn (Crataegus spp.) and berberine derived from the Berberidaceae family. Several different studies indicate important cardiovascular effects of hawthorn and berberine. For...

Hybridization of Non-Native Dune-Building Beachgrasses on the U.S. Pacific Northwest Coast: Characterization of Functional Morphology, Hybrid Swarm Composition, and Ecological Consequences of Ammophila arenaria × A. breviligulata

Creator:: Mostow, Rebecca S.
Abstract:: The rates of biological introductions and invasions are increasing, driving up the associated harms to ecosystems and economies. The spread and effects of invasive organisms depend on the specifics of the introduction, the character of the invaded ecosystem, and multiple traits of the invasive organism itself. One mechanism by which...

Timelines for English language acquisition : a study of the rates of second language acquisition among Hispanic English language learners including exceptionalities

Creator:: Dixon, Jennifer J.
Abstract:: This study explores No Child Left Behind's required timetable for English language learners (ELLs) to reach English language proficiency within five years, as outlined in the Annual Measurable Achievement Outcomes (AMAOs), despite the lack of research evidence to support this as a reasonable expectation. Analysis was conducted on the archived...

A fistful of Astragalus : phenotypic and genotypic basis of the most taxon rich species in the North American flora

Creator:: Knaus, Brian J.
Abstract:: The study of the infra-specific ranks (i.e., subspecies and variety) can be considered the study of the process of speciation. Astragalus lentiginosus Douglas ex Hooker (Fabaceae) is the most taxon rich species in the U.S. flora currently including 40 taxonomic varieties. These varieties were described using traditional taxonomic methods primarily...
