In this webinar, Jonny Armstrong will present NW CASC-supported research on trout, temperature, and pathogens in the Upper Klamath Basin, and Ian Tattam will discuss the Oregon Department of Fish & Wildlife’s work on non-native bass and juvenile steelhead interactions in the John Day River.

An underwater photo of a rainbow trout surrounded by blue water (image by Jason Ching) serve as the background for white text that says "Something Warm in the Water: Temperature, Pathogen, and Invasive Species Impacts on Freshwater Fishes, Zoom webinar, Tuesday, July 15, 2025, 11 AM–noon (Pacific)." Circular image insets show portraits of the two speakers alongside talk and speaker information, as follows: "Beer and Gasoline Don't Mix—Do Bass and Steelhead? Ian Tattam, Eastern Section Science Program Manager for Oregon Department of Fish & Wildlife" and "Exploring how water temperature and pathogens shape the distribution of native and non-native trout in the Upper Klamath Basin, Jonny Armstrong, Associate Professor, Oregon State University." Also included, in white, are the logos for the Northwest RISCC Management Network & Northwest Climate Adaptation Science Cente.

Join us for some fishy summer fun at our next webinar, "Something Warm in the Water: Temperature, Pathogen, and Invasive Species Impacts on Freshwater Fishes" on Tues., July 15, 11am PT, featuring speakers Jonny Armstrong and Ian Tattam!

An illustration of three color morphs of the European green crab (red, dark green, and lighter green) alongside grass, clams, and juvenile Dungeness crabs. Text around and below the illustration reads: Impacts: European green* crab has direct and indirect negative ecological impacts on culturally and economically important PNW species. Destroys aquatic vegetation, including eelgrass (Zostera marina)3 while searching for food, degrading habitat for many species, including salmon, shellfish, and waterfowl. Major predator of clams, mussels, & oysters. Eats & outcompetes juvenile Dungeness crabs (Metacarcinus magister). *They’re not always green! Color varies from red and brown to dark green.

The European green crab has known and potential economic, cultural, and ecological impacts in the NW + beyond.
