The past few years have seen an absolute revolution in genomic technologies and their
potential applications to ecology and evolutionary biology research. Such advances open …

Determining how environmental conditions contribute to divergence among populations and
drive speciation is fundamental to resolving mechanisms and understanding outcomes in …

The origin of species is a central topic in biology. Ecological speciation might be a driver in
adaptive radiation, providing a framework for understanding mechanisms, level, and rate of …

It is well recognized that environmental degradation caused by human activities can result in
dramatic losses of species and diversity. However, comparatively little is known about the …

Anadromous, resident, and landlocked Arctic char (Salvelinus alpinus) differentially
experience drift and gene flow, making them ideal for studying incipient divergence. We …

Adaptive radiation is the diversification of species to different ecological niches and has
repeatedly occurred in different salmonid fish of postglacial lakes. In Lake Tinnsjøen, one of …

Resource polymorphism may play an important role in the process of speciation. The Arctic
char (S alvelinus alpinus) exhibits great phenotypic and genetic diversity across its range …

A fundamental issue in the management and conservation of biodiversity is how to define a
population. Spatially contiguous fish occupying a stream network have often been …

While it is likely that ecological context is important, the factors that facilitate and maintain
variable levels of intraspecific diversity in Salmonidae fishes across environments remain …

The divergence of reproductive strategies is an important development toward intraspecific
diversification. We describe contrasting spawning patterns of parapatric and sympatric Arctic …
