Algae in Bowles Creek in the Taylor Valley of southern Victoria Land. Studies done by Diane McKnight, University of Colorado, a member of the Long Term Ecological Research (LTER), show that the abundance of algae and mosses in dry valley streams appears to be controlled by geomorphology or gradient and flow conditions. Studies also show that algal species are spatially segregated across the stream channel according to their adaptations to fast, slow, or marginal stream environments.
