... C. do not occur in the Mackenzie or Yukon River drainages of the province, and 11 of the 33 species in the latter area occur nowhere on the Pacific slope. Some proposed water diversions for hydroelectric development would cross the continental divide, and are likely to produce striking changes in fish distribution. A proposed Liard-Stikine diversion would probably introduce several species, including trout, into the upper Liard River, and several other species, including northern ...

The only significant difference in allelic frequencies between the two populations occurred at the P locus. An apparent deficit in the observed frequency of type A 1 , and hence a departure from equilibrium, at Upper Laird could not be tested for significance due ...
