Assessing the feasibility of a sea otter reintroduction to Oregon through a coupled natural-human lens

Creator:: Curran, Lorne S., Kone, Dominique V., and Wickizer, Benjamin J.
Abstract:: Sea otters fulfill a keystone role in several Northeastern Pacific nearshore ecosystems. However, their influence has been absent in Oregon coastal waters since their extirpation in the 19th and early 20th century. Interest has been growing for a translocation attempt to reintroduce sea otters to Oregon from one or more...

A decade of tidal wetland development at the Ni-les’tun restoration project on the southern Oregon coast

Creator:: Janousek, Christopher, van de Wetering, Stan, Brophy, Laura, Cornu, Craig, and Tice-Lewis, Maxwell
Abstract:: The Ni-les’tun tidal wetland restoration project in the Coquille River Estuary in southern Oregon is one of the largest and most well-studied tidal restoration projects on the Pacific Northwest coast. However, ecological data on restoration effectiveness and ecosystem change following restoration are relatively rare for projects more than a few...

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...

Development and Evaluation of a Static Land-Based Aquaculture System for Pacific Dulse (Devaleraea mollis): Environmental and Nutrient Requirements

Creator:: Chatfield, Marcus W.
Abstract:: Devaleraea mollis (Pacific Dulse) is becoming a popular food for human consumption. Previously, Pacific Dulse has been used as a nutrient source for cultured abalone species, with some historical food use by indigenous peoples, while the closely related Atlantic dulse (Palmaria palmata) has a long-documented history of use in cuisine...

Large Downed Wood as Post-fire Refugia for Terrestrial Salamanders in Pacific Northwest Forests

Creator:: Stephens, Paige N.
Abstract:: Climate change, wildfire, timber harvest, and land conversion alter the availability of downed wood in forests of the western United States. Numerous taxa rely on downed wood for temperature and humidity refugia, and downed wood may play a key role in enabling the persistence of climate-sensitive, low-vagility species like terrestrial...

A Contingency-Based Evaluation for Beaver Restoration of Salmon Habitat in Oregon Coastal Streams

Creator:: Stevenson, John R.
Abstract:: Streams across the western United States are impaired from human alterations that have reduced freshwater habitat by simplifying channel complexity and disconnecting floodplains (Knox et al., 2022; Waples et al., 2008; Wohl, 2014). Climate change is likely to continue exacerbating these risks by warming summer surface stream temperatures (Crozier et...

Ringtail (Bassariscus astutus) Survival, Home Range Size, and Rest Site Use in Southwest Oregon

Creator:: Somers, Lindsay N.
Abstract:: The ringtail (Bassariscus astutus) is a small, nocturnal, meso-carnivore that occupies mid-elevation forests in the southwest portion of Oregon. Ringtail are fully protected within Oregon, but a species of conservation concern as they may be vulnerable to habitat loss and fragmentation. Limited data exists regarding ringtail ecology in forested ecosystems,...

Lamprey of the Goose Lake Basin: A Multi-Scale Habitat & Distribution Analysis

Creator:: Dickey, Jacob C.
Abstract:: Two ecologically important lamprey species found in the endorheic Goose Lake Basin face conservation threats; however, relatively little is known about their habitat needs or spatial distribution. Lamprey and their habitat are often found to be patchy; to evaluate these relationships for the lamprey in this basin, I utilized a...

Diving into Diversity: Fish Populations and Climate Resilience in an Endorheic Basin

Creator:: Dew, Aleah
Abstract:: The Goose Lake Basin, situated on the border of Oregon and California, USA, faces significant challenges from drought, wildfire, and other environmental stressors. This region hosts numerous endemic fish species such as the Goose Lake redband trout (Oncorhynchus mykiss newberri), Goose Lake lamprey (Entosphenus sp.), Goose Lake tui chub (Siphateles...

Fall Phenology, Movement, and Roost use of Little Brown Bats (Myotis lucifugus) and California Myotis (Myotis californicus) at Mount Rainier National Park

Creator:: Hansen, Michael
Abstract:: Little is known about the fall and winter ecology of hibernating bats in western North America. Filling knowledge gaps for these populations has become more urgent with the westward spread of the white-nose syndrome, a disease that infects bats during hibernation. Due to the thermal requirements of the fungal pathogen...
