Demography, home range, and habitat selection of northern spotted owls in the Ashland Watershed

Creator:: Schilling, Jason W.
Abstract:: Northern Spotted Owls (Strix occidentalis caurina) inhabit productive forests that historically supported frequent, large, variable-severity fires in the Klamath province of southwestern Oregon occur in complex. The potential for high-severity wildfire remains high throughout this region, so remaining spotted owl habitat is at risk. An adaptive management approach to fire...

Making the Connection: Linking Stress Physiology of Juvenile Northern Spotted Owls to Environmental Variation and Long-term Survival

Creator:: Mikkelsen, Ashlee J.
Abstract:: The northern spotted owl (Strix occidentalis caurina; spotted owl) is of conservation concern and endemic to mature forests of the Pacific Northwest. Adult survival has a strong effect on population growth rate, but juvenile survival and recruitment are also important components of population change. Despite the importance of this life...

Passive acoustic monitoring of owls: two studies in forested landscapes of the Pacific Northwest

Creator:: Duchac, Leila S.
Abstract:: Nearly all birds communicate through sound, and there has been much study of avian populations and communities using song and other vocalizations. Owls are no exception as they defend territories, advertise for mates, and defend against threats using various vocalizations. However, due to their generally nocturnal habits, some owl species...

Top-down Influences of bald eagles on common murre populations in Oregon

Creator:: Horton, Cheryl A.
Abstract:: Populations of organisms are influenced by both top-down (predator driven) and bottom-up (environment or resource driven) effects. Seabird research has largely focused on bottom-up factors influencing reproduction, with little emphasis on top-down. Our goal was to better understand top-down impacts on colonial nesting seabirds over a range of spatio-temporal scales....

Effects of Habitat Characteristics, Weather and Presence of Barred Owls (Strix varia) on Occupancy Dynamics and Breeding Propensity of Northern Spotted Owls (S. occidentalis caurina) in Mount Rainier National Park

Creator:: Mangan, Anna O.
Abstract:: For over 100 years, National Parks have existed to preserve America’s natural and cultural heritage for current and future generations. As environmental pressures on wildlife and habitats have increased in recent decades, National Park lands have become important protected areas for many threatened and endangered species. Conservation and management of...

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...

Estimation of Population Age Structure, Detection Probability, and Density of Red Tree Voles in Oregon

Creator:: Marks-Fife, Chad A.
Abstract:: Red tree voles (Arborimus longicaudus) are a unique species of Arvicoline rodent found in western Oregon and northwest California. Their preferred habitat is mature and old-growth coniferous forest dominated by Douglas-fir (Pseudotsuga menziesii). Tree voles are an important prey item for northern spotted owls and many other predators, but are...

Historic Survival Rates and Cause-Specific Mortality for Columbian Black-Tailed Deer in Southwest Oregon

Creator:: Groot, Kevyn A.
Abstract:: In contrast with other Odocoileus species, Columbian black-tailed deer (Odocoileus hemionus columbianus) population dynamics are not well understood throughout the species’ range. Concerns over apparent long-term population declines have prompted efforts to fill basic knowledge gaps including estimates of vital rates (fecundity, recruitment and survival) and cause-specific mortality. The Oregon...

Survival Rates and Cause-Specific Mortality of Mule Deer in South-Central Oregon

Creator:: Mulligan, Elizabeth M.
Abstract:: It is critical for wildlife managers to understand the population dynamics of a harvested species, particularly for ungulates, which are a valuable wildlife resource. Due to concerns that mule deer (Odocoileus hemionus) populations in Oregon were declining, more comprehensive data on population vital rates and the factors potentially affecting them...

Provisioning, growth and survival of Adélie penguin chicks at Cape Crozier, Ross Island, Antarctica

Creator:: Jennings, Scott
Abstract:: Understanding the factors that contribute to or limit reproductive success is a fundamental objective of the field of ecology, providing insight into the ways ecosystems function and facilitating better management of natural resources. Behaviors that benefit offspring often increase costs to parents, and thus parents must adjust their level of...
