TL;DR: It is argued that non-model species studied in their ecological context such as whitefish will play an increasingly important role in generalizing knowledge of speciation and the joint use of recent biotechnological developments will provide a powerful means to address issues raised by observations made to date.

TL;DR: In this paper, the authors studied nine Norwegian lakes in three watercourses, which each harboured pairs of divergent whitefish morphs and compared the morphology and life history of these morphs, documented the extent of genetic differentiation between them and contrasted the niche use of sympatric morphs along both the habitat and resource axes.

TL;DR: In this article, the authors compared mtDNA and gill-raker number variation in populations of the European whitefish Coregonus lavaretus (L.) species complex to illuminate their evolutionary history, and discuss mechanisms behind diversification.

TL;DR: An up-to-date synthesis of the matrilineal phylogeography of a uniquely well-studied Holarctic mammal, the brown bear, is provided by presenting a DNA sequence derived from one of the earliest known fossils of a polar bear, a species that shares a paraphyletic mitochondrial association with brown bears.

TL;DR: It is found that deep‐, shallow‐, river‐ and bay spawning populations are distinct morphs in Lake Femund, and the adaptive gene combinations behind the four morphs seem to have originated within the lake, although the lake could have been colonized from more than one source population.
