The European green crab (Carcinus maenas) has persisted in Oregon and Washington coastal estuaries since the late 1990s. A strong year class arrived during the 1998 El Niño, but numbers decreased and remained below 1 per trap per day until the arrival of the 2015-2016 El Niño. Since then, numbers...

The European green crab (Carcinus maenas) has persisted in Oregon and Washington coastal estuaries since the late 1990s. A strong year class arrived in the Davidson Current during the 1998 El Niño, but numbers decreased and remained below 1 per trap per day until the arrival of the 2015-2016 El...
Isotope and stomach content data from piscivorous reservoir fishes collected from Hills Creek (isotopes; 43°40′16″N 122°25′33″W) and Lookout Point (isotopes and stomach contents; 43°53′48″N 122°43′34″W) reservoirs located on the Middle Fork Willamette River, Oregon. Additional details can be found in the related publication.
Isotope sampling was conducted under OSU Institutional...
Riparian ecosystems provide critical habitat for a broad diversity of aquatic and terrestrial species. However, due to their connectivity along river corridors, and the tendency for people to build roads, infrastructure, and other settlements next to rivers, riparian ecosystems are vulnerable to colonization by invasive plant and animal species. Early...
European green crab, Carcinus maenas, trapped and collected in coastal Oregon and Washington coastal estuaries during the 2019. Data for individual crabs include: estuary, site, date of collection, sex, carapace width, weight, molt stage (color of abdomen), missing limbs, estimated year class, method of collection, and name of collector.

The European green crab (Carcinus maenas) has persisted in Oregon and Washington coastal estuaries since the late 1990s. After the arrival of a strong year class in 1998, significant recruitment to the populations occurred only in 2003, 2005, 2006, 2010, 2015, 2016, 2017, 2018 and 2019. Warm winter water temperatures,...
This dataset contains the taxonomic classifications of environmental DNA (eDNA) sequences obtained from Fall Creek, Oregon, via microfluidic multiplex PCR (Fluidigm Access Array) and high-throughput sequencing. It is accompanied by electrofishing counts taken at the same time as the eDNA samples. Metadata and R scripts are provided to analyze the...
Great Lakes coastal wetland communities are threatened by the impacts of invasive plants on ecosystem function and biodiversity. What allows invasive plants to become dominant in invaded communities can be hard to define and context-dependent. Traits associated with invasion success in wetland systems – rapid vegetative growth, competitive superiority in...
