American pikas (Ochotona princeps) are considered an indicator species of climate change. Adaptations for cold climates and active winters make pikas particularly sensitive to increasing temperatures. This, combined with evidence that multiple historically occupied populations have been extirpated within the past century, contributed to American pikas becoming a focal species...
Climate change is arguably the greatest challenge to conservation of our time. Most vulnerability assessments rely on past and current species distributions to predict future persistence but ignore species’ abilities to disperse through landscapes, which may be particularly important in fragmented habitats and crucial for long-term persistence in changing environments....

I first met Jessica at a wedding reception I attended with my host family my first night in Lakeview. She told me she worked at the Extension Office, so I’ve seen her around ever since and interviewed her while we were both there to get...
Low-level nuclear power plant outages in the United States can lead to unanticipated costs, potentially compromising the expected operation lifetime of the plant. Nuclear power plants are complex systems of interfacing components and highly regulated processes. This inherent complexity makes predicting outages from system dependencies very challenging. When outages do...
The effects of potential parental egg production and
environmental factors on year-class strength (YCS) of petrale sole
(Eopsetta jordani) were investigated in two areas off Oregon and
Washington (Pacific States Marine Fisheries Commission areas 2B: 42°
50'N - 44°18'N, and 3A: 45° 46'N - 47°20'N). Indices of YCS based on...
As laws regarding medical and recreational cannabis use are changing across the United States, one must begin to understand the effects among individuals with chronic pain. Specifically, it is unclear how legalization may change their use of marijuana and opioids to self-medicate or for recreational use. To address these questions,...
The extent of biological invasions, their role on the feeding of
native fishes and their impact on community stability were
investigated in Alsea Bay and Yaquina Bay, two estuaries on the
central Oregon coast, USA. Most nonindigenous species (NIS)
introduced in these intermediately invaded estuaries are
considered byproducts of culturing...
The Arc Marine data model is a generalized template to guide the implementation of geographic information systems (GIS) projects in the marine environment. Arc Marine developed out of a collaborative process involving research and industry shareholders in coastal and marine research. This template models and attempts to standardize common marine...
