Abstract: | The electrophoretic patterns of lactate dehydrogenase, phosphoglucomutase and total muscle proteins distinguished the species Etheostoma flabellare, E. kennicotti and E. squamiceps from each other and from three species of the E. virgatum group (E. virgatum, E. obeyense and E. barbouri), which all possessed identical patterns. Etheostoma flabellare, the species with the widest geographic range, possessed the greatest amount of genetic variation in all three protein systems studied. Patristic distances were calculated via an unrooted Wagner network. Using this method it was shown that E. flabellare was the most divergent species, E. kennicotti and E. squamiceps were less divergent, and the members of the E. virgatum group clustered closely. |
