Chrissy began working for IZ&G on the SFBay:2K Project in the year 2000. This four-year Academy project combined an educational program with a biodiversity inventory of the benthic invertebrates and fish living in San Francisco Bay (considered by many as the world’s most biologically invaded estuary). During this project Chrissy and her colleagues collected and identified voucher specimens for the Recent Invertebrates Collection, trained local students and educators in taxonomy, and co-authored a fieldguide to benthic animals of the Bay. Since then, she has participated in numerous departmental projects, the Academy’s Travel Program, and research expeditions to collect marine polychaete worms and other invertebrate specimens. She works daily to maintain IZ&G’s research collections and database.
While at CAS, she obtained her Master of Science in Ecology and Systematic Biology from San Francisco State University. Her research utilizes molecular and morphological data to delineate cryptic species and track sources of invasion for non-native intertidal polychaete scaleworms. Cryptic species are identical in their appearance, or nearly so, yet differ in their evolutionary origins (and quite often other aspects of their biology as well). Non-native (also known as exotic, non-indigenous, or introduced) species are extremely common within marine invertebrate animals, as they are easily transported among regions via aquaculture, bait release, vessel fouling, and ballast water discharge. San Francisco Bay is an excellent place for studying marine biological invasions…and worms!
