Watershed Controls on Biogeochemical Processes in Aquatic Ecosystems
Freshwater ecosystems provide critical services to sustain human livelihoods, such as fisheries, agriculture and clean water, yet face increasing demands from rapidly expanding populations and globalizing societies. In ... -
Watershed Controls on Stream Thermal Regimes: Effects on Salmon Spawn Timing and Species Interactions
Global surface temperatures are warming at unprecedented rates and are expected to continue to warm for the rest of the century. Yet, we know very little about how freshwater ecosystems will respond to a warmer climate. ... -
Watershed controls on streamwater biogeochemistry in a large boreal river network
Streamwater chemistry forms the base of aquatic food webs and reflects both watershed and instream controls, yet the balance of these controls has not been quantified across large river networks. Boreal river networks in ... -
Wildfire effects on stream metabolism: Aquatic succession is mediated by local riparian succession and stream geomorphology
As climate change shifts and intensifies fire regimes, it is important to understand stream ecosystem responses to fire. How stream metabolism responds remains largely unexplored. We investigated effects of fire severity ... -
Withering Syndrome Disease Dynamics in Wild and Cultured Northeastern Pacific Abalones
Withering syndrome (WS) is a chronic bacterial disease of abalones, Haliotis spp., caused by a Rickettsia-like organism (WS-RLO). The etiological agent, Candidatus Xenohaliotis californiensis, occurs along the eastern ... -
Yearling Chinook salmon ecology and behavior during early-ocean migration
(2014-04-30)High mortality rates of Pacific salmon (Oncorhynchus spp.) in the nearshore ocean environment of the Columbia River (Northwest USA) is one of several key factors limiting recovery of these threatened and endangered fish. ...
