| parallelism in the oxygen transport system of the lake whitefish: the role of physiological divergence in ecological speciation. | in north america, populations of lake whitefish (coregonus clupeaformis) have evolved sympatric 'dwarf' and 'normal' ecotypes that are associated with distinct trophic niches within lakes. trophic specialization should place diverging physiological demands on individuals, and thus, genes and phenotypes associated with energy production represent ideal candidates for studies of adaptation. here, we test for the parallel divergence of traits involved in oxygen transport in dwarf and normal lake wh ... | 2012 | 22724454 |
| oxidative phosphorylation gene transcription in whitefish species pairs reveals patterns of parallel and nonparallel physiological divergence. | across multiple lakes in north america, lake whitefish (coregonus clupeaformis) have independently evolved 'dwarf' and 'normal' sympatric species pairs that exhibit pronounced phenotypic and genetic divergence. in particular, traits associated with metabolism have been shown to be highly differentiated between whitefish species. here, we examine the transcription of genes associated with the five mitochondrial and nuclear genome-encoded oxidative phosphorylation (oxphos) complexes, the primary p ... | 2012 | 22830417 |
