| Notes | The three-spined stickleback is a highly adaptive species, capable of thriving in oceanic, estuarine and freshwater environments. Its abundance and differing life histories make it a good subject for studying the interplay between environment and genetics. In this paper, the authors exhaustively examine the genetic and physiological characteristics of this species. “To address the degree of congruence between genetic and phenotypic divergence, we directly compared Oregon stickleback to much younger (post-glacial) Alaskan populations. We found phenotypic variation in Oregon Stickleback to be primarily partitioned between oceanic and freshwater habitats . . . However, the main axis of genetic divergence was between coastal and inland regions regardless of habitat type” (from the Abstract). Interestingly, scattered populations of inland fish retain physical characteristics typical of the oceanic residents. |
