Exposure to chemically complex, polluted sediments and water during early development can be lethal to a variety of species. Contaminated sediments accumulate in food webs or directly affect heath of marine life. In this course, students will utilize California Purple Urchin (Strongylocentrotus purpuratus) embryo and larval development to conduct toxicity testing in the sediments collected from the Tijuana River Estuary and preform ecological risk assessment.
Besides learning how to maintain and culture animals in the lab and perform fertilization tests utilizing microscopy to assess embryo morphology, students will (virtually) tour the estuary, collect sediment and water samples. They will learn to deploy passive sampling devices (PSDs) and perform toxicity testing on developing urchin embryos.
Upon collecting data and performing statistical analysis, students will correlate phenotypic changes observed among developing embryo populations with estuarine sediment, water and PSD chemistry data. Students will showcase their work and share their research with fellow scientists, academic, government officials and life-science industry leaders during a formal seminar symposium at the conclusion of the course.
