Characterizing the Spread and Consequences of Mycoplasma ovipneumoniae on Bighorn Sheep (Ovis canadensis) in the Northern Basin and Range Ecosystem

Creator:: Spaan, Robert S.
Abstract:: North American bighorn sheep (Ovis canadensis) have experienced significant declines and population extirpations due to novel pathogens such as Mycoplasma ovipneumoniae. This disease continues to limit the population restoration of bighorn sheep. Therefore, understanding the demographic consequences of pathogen presence and the risk of contact between bighorn populations and potential...

Lower Deschutes River, Oregon: discharge and the fish environment

Creator:: Aney, Warren W., Montgomery, Monty L., and Lichens, Allan B.
Abstract:: The lower Deschutes River of northcentral Oregon has a historically uniform discharge record. Significant reductions in discharge below the seasonal norms will degrade the environment for migratory and resident salmonids by increasing siltation and gravel compaction, and by reducing intragravel water dissolved oxygen content. Fish spawning will be limited by...
