Wildfire Severity Has a Minimal Influence on Pollen Diversity Used by Developing Mason Bees (Osmia lignaria) in Mixed Conifer Forest

Creator:: Bell, Nicole C. S.
Abstract:: Native bees are critically important organisms that support biodiversity and crop production via their pollination services. Wildfires in temperate conifer forests can increase bee abundance and flowering plant density due to increased light exposure, but little information is available regarding how wildfire severity influences provisioning to bee offspring, which is...

Early competitive environments differentially influence stress axis responses in sympatric, ecologically similar songbirds

Creator:: Hardt, Braelei M.
Abstract:: 1. Early competitive environments can shape the development of offspring across taxa. For example, competition for food can have downstream effects on offspring phenotypes and fitness; however, little is known about how early competition influences the development of the hypothalamic-pituitary axis and its potential tradeoff with growth. Because baseline and...

An Assessment of Black-backed Woodpecker (Picoides arcticus) Vital Rates in Green and Burned Forests within a Pyrodiverse Landscape Mosaic

Creator:: Kerstens, Mark E.
Abstract:: Vital rates and population connectivity are fundamental concepts in animal ecology and such information is critical for successful conservation planning. The Black-backed Woodpecker (Picoides arcticus) is a species of conservation concern because of its strong association with forests recently burned by high-severity wildfire. However, several recent studies have found that...

Evaluating the response of bees to visual attractants in resource-poor environments

Creator:: Parvin, Lucas
Abstract:: Bee populations are declining around the globe, while the need for their pollination services is increasing with growing food demands by an expanding population. There is a need for innovative practices to increase pollination in agricultural environments without harming wild bee populations. However, the use of artificial visual attractants has...

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....

Supplemental Feeder Use by Free-Living Black-capped Chickadees (Poecile atricapillus) in a Mediterranean Climate

Creator:: Lajoie, Janel L.
Abstract:: The majority of households in the U.S., Great Britain, and Australia feed wild birds, and 53 million people in the U.S. spent more than $5 billion on bird food and feeding accessories in 2016. Given the massive scale over which it occurs, purposeful feeding of wild birds has the potential...

Created Snag Dynamics and Influence on Cavity-nesting Bird Communities over 25 years in Western Oregon

Creator:: Barry, Amy Marie
Abstract:: Snags provide critical habitat for nearly one-third of wildlife species in forests of the Pacific Northwest, so historic declines in snags are thought to have had a strong impact on biodiversity. Resource managers often create snags to mitigate the scarcity of snags within managed forests, but information regarding the function...

Combined Effects of Intensive Forest Management and Microclimate on Reproduction in a Cavity-Nesting Songbird

Creator:: Jones, Kristin N.
Abstract:: Future scenarios of global climate change rely on large-scale climate envelope models that do not account for local climatic conditions to which organisms most closely respond. Shifts in species distributions and phenology driven by climate change are well-documented, yet we lack a strong understanding of how climate change will influence...

Extrinsic and Intrinsic Factors Associated with Reproductive Success of Caspian Terns (Hydroprogne caspia) at East Sand Island, Columbia River Estuary

Creator:: Bailey, Olivia A.
Abstract:: Declines in wild salmonid (Oncorhynchus spp.) populations in the Columbia River basin have resulted in managers identifying that avian predation on juvenile salmonids is an important limiting factor for salmonid recovery. Caspian Terns (Hydroprogne caspia), particularly those nesting in the Columbia River estuary, were identified as key avian predators that...

Resource Selection, and Demographic Rates of Female Greater Sage-Grouse Following Large-Scale Wildfire

Creator:: Foster, Lee
Abstract:: Understanding the effects of habitat disturbance on a species' habitat selection patterns, and demographic rates, is essential to projecting the trajectories of populations affected by disturbance, as well as for determining the appropriate conservation actions needed to maintain those populations. Greater sage-grouse (Centrocercus urophasianus) is a species of conservation concern...
