Terrestrial land use activities present cross-ecosystem threats to riverine and marine species and processes. Specifically, pesticide runoff can disrupt hormonal, reproductive, and developmental processes in aquatic organisms, yet non-point source pollution is difficult to trace and quantify. In Oregon, U.S.A., state and federal forestry pesticide regulations, designed to meet regulatory...
Historical forest harvesting practices were reviewed in the original Alsea Watershed Study where they found increased energy
loading to the stream and produced higher stream temperatures. This was an important early research site that led to the
development of contemporary forest management practices to protect water quality and fish habitat...
Despite progressive policies and continued advances in ocean management, numerous shifts associated with global changes have been observed in marine ecosystems in recent years, including warming, ocean acidification, and deoxygenation. As global change accelerates, science is needed to inform evidence-based management strategies for continued ecosystem services. Resilience management, in which...
Washington State fisheries and Washington State Treaty Tribes are becoming increasingly restricted in harvest of wild salmon due to US Endangered Species Act listings of salmon species, marine mammal predation by both ESA listed Southern Resident Killer Whale (SRKW) and US Marine Mammal Protection Act protected pinnipeds, salmon habitat destruction,...
Understanding the causal links between riparian forests, streams, and salmonids is important to help understand the likely effects of forest management practices. Previous studies have identified three major causal pathways (Instream Cover, Light, and Hydrology) through which riparian forests influence streams, and ultimately stream fishes. To evaluate the potential importance...
Pacific salmon are culturally and economically important species to Southeast Alaska, where there is a history of large wild runs and supplemental production from hatchery programs. Salmon management in Alaska is divided amongst various governmental agencies. Non-governmental organizations also play a pivotal role in salmon management. To fulfill the requirements...
The dynamic nature of most environments forces many animals to move to meet their fundamental needs. This is especially true in aquatic environments where shifts in spatial ecology (which are a result of movements) are among the first adaptive responses of animals to changes in ecosystems. Changes in the movement...
The United Nations Food and Agriculture Organization (FAO) in the State of World Fisheries and Aquaculture 2018, has observed that the trend of the world’s marine fish stocks has been overexploited, depleted, and has exhibited decreasing trend within the fraction of biologically sustainable levels. While these situations are an alarming...
Blue-striped Brodiaea or Leach's Brodiaea (Triteleia hendersonii Greene var. leachiae [Peck] Hoover, or Brodiaea hendersonii Wats. var. leachiae ) Lily Family (Liliaceae) is found in the foothills of the Siskiyou Mountains of Curry, Coos and Josephine Counties of southwestern Oregon. It is occurs in a variety of habitats including meadow...
