ABSTRACT

Members of the Colorado Ri ver Gi I a compl e;.; were e;: ami ned
cytogenetically and electrophoretically to. establish non-morpho-
logical and age-independent criteria for distinguishing between
morphospecies. A non-lethal field sampling procedurE wa-
developed for obtaining living material usable for tissue culture
