Hatcheries are used to produce salmon to augment the number of fish available for harvest, and to supplement wild populations that may be threatened with extinction. Although traditional hatchery rearing methods can produce many fish, they can pose risk to wild populations because they tend to produce salmon with lower...
The decline of the Chinook Salmon has been a mystery of recent years due to their decline. It has been speculated that wild origin salmon have more vigor and survivability than hatchery reared fish. This is thought to be due to rearing conditions, possibly affecting sensory organ development. The sensory...
Due to public and regulatory restrictions, genetic containment technology is critical for research and development of transgenic trees in forestry. A multi-year field trial demonstrated that the RNAi-LFY construct successfully induces sexual sterility in 6K10 poplar (Populus alba) without visible effects on vegetative development. However, its limited number of replicates...
Polycystic Ovary Syndrome (PCOS) is an idiopathic disorder prevalent in ~5-10% of reproductive-aged women. In PCOS women who become pregnant, many experience complications including increased susceptibility of having a miscarriage, high blood pressure, and gestational diabetes, among others. Additionally, exposure to PCOS may have transgenerational impacts: offspring may be at...

Volatile organic compounds (VOCs) play an integral role in climate change and as a carbon source for organisms living in a marine environment. These compounds have many sources, but the impacts of biogenically produced VOCs is not fully known. Phaeodactylum tricornutum was studied under axenic ideal growth conditions to determine...
Phytophthora ramorum is the causal agent of Sudden Oak Death (SOD), which is an economically and environmentally important disease causing up to 80% mortality of tanoaks in Pacific Northwest coastal forests (LeBoldus et al., 2022). There are currently four clonal lineages in the United States and Europe, named North America...
There is a growing need to establish alternative approaches for assessing hazard from chemical exposure compared to the traditional method of animal testing. Approaches that relate chemical structure to biological activity are gaining acceptance in the field as in silico methods for characterizing and predicting chemical toxicity. In this study,...
Top predators play important roles in regulating communities and ecosystem processes in freshwater ecosystems. In the headwater stream network, it is crucial to understand the interspecific interaction between multiple predators. In Oregon forested ecosystems, Coastal Giant Salamander (Dicamptodon tenebrosus) and cutthroat trout (Oncorhynchus clarkii) are the top predators in many...
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...
