Drivers and Impacts of a Recent Annual Grass Invasion: Ventenata dubia and Fire in the Inland Northwest

Creator:: Tortorelli, Claire M.
Abstract:: Biological invasions threaten native biodiversity, alter ecosystem function, and are a major cause of economic losses across the planet. The most impactful invaders alter disturbance regimes and initiate state shifts to outside the historical range of variability of the ecosystem. Concern for ecological and economic losses has prompted a rapid...

Assessing the sustainability of management practices for planted forests across an environmental gradient in New Zealand

Creator:: Kiyvyra, Alicia L.
Abstract:: Sustainable management of planted forests requires maintenance of soil function to promote 1) root growth; 2) storage and cycling of water and nutrients; 3) optimal gas exchange; and 4) biological activity. Soil quality measurements can be used to monitor short- and long-term changes in these soil functions, allowing managers to...

Virulence factors of Aeromonas salmonicida and their interaction with the salmonid host

Creator:: Rockey, Daniel D.
Abstract:: Selected secreted and cellular virulence factors of Aeromonas salmonicida were examined. A protocol was developed for the separation of two secreted proteases (P1 and P2 protease), and a trout erythrocyte specific hemolysin (T-lysin) from supernatants of cultures of the bacterium. Distinctions between the proteases were demonstrated using molecular weight determinations,...
