March 20, 2020  ***EVENT CANCELED***
“Anaerobic and aerobic life in the Bay mud” by Sean Craig. 

Humboldt State biology professor Sean Craig will enlighten us about marine animals in the aerobic and anaerobic mud of Humboldt Bay. Infaunal marine invertebrates living in the mud or epifuanal invertebrates on the surface of the mud often are overlooked, especially by birdwatchers, but play an important role in soft sediment communities. This talk will touch upon bivalves, innkeeper worms, crustaceans, and other mud-dwelling invertebrates and their connections to higher trophic levels (e.g., birds), as well as to the water column above them.

Sean teaches classes in zoology, intertidal ecology, and an occasional seminar on invasive species.  His research focuses on the community ecology of Marine Protected Areas on rocky and sandy shores, as well as in subtidal kelp beds.
