Atlantic Puffin (Fratercula arctica) Foraging Ecology During Marine Heatwave Conditions

Creator:: Kennerley, William L.
Abstract:: Marine heatwaves (“MHWs”) are discrete periods of anomalously warm ocean conditions that can lead to shifts in the distribution and abundance of marine organisms. Low-trophic level, pelagic forage species are frequently among those affected by MHWs, often resulting in considerable impacts upon their predators. In the North Atlantic Ocean, Atlantic...

Assessing the Impacts of the Red Imported Fire Ant on First-Generation Monarch Butterfly Reproductive Success in a Texas Coastal Prairie

Creator:: Sutherland, Remy C.
Abstract:: In recent years, monarch butterfly (Danaus plexippus) populations have declined at an alarming rate resulting in an extensive conservation effort across the species’ migratory range. One hypothesis for declining populations is decreased reproductive success during spring migration. The eastern monarch population’s first annual generation occurs in the early spring when...

Foraging ecology of barred owls where they are outcompeting the threatened northern spotted owl

Creator:: Baumbusch, Ryan C.
Abstract:: Following European-American colonization of North America and associated landscape changes, barred owls (Strix varia) underwent a dramatic expansion of their historical range. The barred owl expanded across the previously tree-less Great Plains that had limited their distribution, and into the forests along the west coast. In these western forests they...

Cultural and Environmental Creencias (Beliefs) and Latin@ Outdoor Recreation in the Willamette Valley of Oregon

Creator:: Justiniano, Isabel
Abstract:: In Oregon, outdoor recreation activities have continued to grow in popularity, as has the overall Latin@ population of the state. With the continual population increase of this ethnic group, researchers have focused on understanding their outdoor recreation habits through an environmental justice lens. This includes accessibility, affordability, and other barriers...

Greater Sage-Grouse (Centrocercus urophasianus) Demographic Rates and Predator Communities in a Degraded Landscape in Modoc County, California

Creator:: Sink, Chelsea E.
Abstract:: The greater sage-grouse (Centrocercus urophasianus: hereafter; sage-grouse) population in Modoc County California is geographically isolated and has been subsidized by translocation to prevent inbreeding depression since 2005. Despite significant efforts to increase the population through translocations and habitat improvement by cutting encroaching western juniper (Juniperus occidentalis), only a single lek...

The Impacts of Juniper Removal on Native Herbaceous Vegetation and Surface-Dwelling Invertebrates in the Sagebrush Steppe

Creator:: Haab, Kimberly A.
Abstract:: Understanding the effects of disturbance and restoration on a species’ habitat is essential for understanding the demographic rates and population trends observed in a species. Sufficient habitat provides the space and resources required for survival and successful reproduction, such as food availability, access to water, protection from predators, protection from...

Characterizing the Spread and Consequences of Mycoplasma ovipneumoniae on Bighorn Sheep (Ovis canadensis) in the Northern Basin and Range Ecosystem

Creator:: Spaan, Robert S.
Abstract:: North American bighorn sheep (Ovis canadensis) have experienced significant declines and population extirpations due to novel pathogens such as Mycoplasma ovipneumoniae. This disease continues to limit the population restoration of bighorn sheep. Therefore, understanding the demographic consequences of pathogen presence and the risk of contact between bighorn populations and potential...

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....

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...

Songbird Mobbing of Northern Pygmy-Owls: A Function of Risk Across Landscapes and Seasons

Creator:: Scott, Madeleine
Abstract:: The evolutionary arms race between predators and prey has led to a diverse set of interactions between species. Prey have developed an array of behaviors designed to reduce their risk of predation. Among those strategies, mobbing is a paradoxical behavior where prey actually approach predators, often in large multi-species flocks....
