    About This Project

    After the last ice age, temperatures in the Northern hemisphere rose and precipitation levels were dramatically altered. We are beginning to understand how these changes impacted many areas, but what about Hawaii? We have dated shells from extinct, endemic Hawaiian snails to this period of global change, and we will use isotopes from these shells to examine how Hawaii's environment changed. We hypothesize that rising temperature and lowered precipitation led to the extinction of these snails.
