Protozoa
of Anerobic Habitats
In reference
to the protozoan communities of extreme habitats, we have conducted surveys
of the free-living flagellates associated with anaerobic habitats and many new
taxa have been described. These communities include obligate and facultative
anaerobes, with many taxa lacking classical mitochondria. Several organisms
have been cultured for detailed morphological, molecular and cell biological
studies. A large number of these taxa are of relevence to attempts to understand
the early evolution of eukaryotic cells. Also of interest, some groups of flagellates
known widely as endoparasites of animals turn out to have free-living members
in external anaerobic habitats.
