Researchers confirmed the highly invasive and destructive European green crab is now present in Skagit Bay — and has gone undetected there for at least a couple of years. The species is one of the most invasive in the marine environment, decimating seagrass fields and outcompeting local species.

Do you study the impacts of #InvasiveSpecies and plan on attending #SCAS_IAGLR2026? Consider submitting an abstract to our proposed session below ⬇️ ⬇️ ⬇️
Calling aquatic invasion scientists!
@veronicagroves.bsky.social and I are co-chairing the session "Invasive Species in Great Lakes Systems" at the 2026 @iaglr.bsky.social - @scas-scsa.bsky.social joint conference in Winnipeg May 25-29th and are looking for talks to feature!

New study from our lab: Feeding efficiency (trophic impact) of goldfish varies with combinations of thermal & salinity conditions typical of urban ponds in north temperate regions. Salinity enhances efficiency at temperatures below the thermal optimum of goldfish.

Highlights from my first field season with the amazing Ricciardi Lab team @ricciardilab.bsky.social!
It has been such a joy learning about this new system, and getting to know my study species!
