THE ZECHMAN LAB:

MOLECULAR PHYLOGENETICS AND EVOLUTION OF MARINE AND FRESHWATER GREEN ALGAE

 
 

    Dr. Frederick W. Zechman's research is focused on the molecular phylogenetics, evolution and ecology of marine and freshwater green algae- organisms that are common to the California coast, vernal pools of the San Joaquin Valley and the rivers and streams of the Sierra Nevada Mountains. Phylogenetic analyses of DNA sequences for these algae address morphological and molecular character evolution, and the historical pattern of marine and freshwater ecological radiations.


    Recent research in the Zechman Lab has focused on the deep-water genera Palmophyllum and Verdigellas, and was featured in a story on the BBC Earth News website. This research has identified the Palmophyllophytes as a previously unrecognized early diverging lineage of green plants.


    Other research in the Zechman Lab is focused on the evolution and biogeography of the pantropical coral reef-inhabiting alga, Caulerpa and related genera and the North Atlantic endemic, Ascophyllum. These investigations will help to understand the evolutionary relationships within the green plant lineage, the biodiversity of marine and freshwater habitats, and rates and patterns of molecular evolution in aquatic organisms.
