Oct 5, 2017. The College of Natural Sciences and Mathematics hosted another successful Undergraduate Research Reception at Sacramento State last week. Over 50 Undergraduate researchers from Astronomy to Biology presented their research posters including lab member, Ethan Roberts. During the summer 2017, Ethan worked with Dr. Davidson through the SURE program to conduct novel marine ecology research. Ethan investigated how burrow shelters made by an invasive isopod, Sphaeroma quoianum, creates a buffered microclimate for other intertidal organisms. Burrows produced a more humid microclimate, which reduced desiccation stress experienced by intertidal crustaceans. This research will help us better understand how habitat-modifying species can affect patterns of abundance and diversity of other marine organisms.
