Résumé

Synopsis: We examined spatial patterns of allozyme variation in three species of intertidal cottids to evaluate how much gene flow occurs between geographically separate populations (most likely via passive dispersal of planktonic larvae by currents). Our results from the analysis of geographical patterns of allele frequencies and, to some extent, from comparison of allele frequencies between newly recruited young and older resident fish are consistent with the notion that sufficient gene flow occurs in these fishes to prevent significant genetic isolation of populations. From these results, we visualize evolutionary changes in populations of these species as occurring most likely over a broad geographic scale, affecting spatially separated but genetically linked populations concurrently, rather than operating independently in individual, genetically isolated populations.
