Arctic char (Salvelinus alpinus) and Dolly Varden (S. malma) are two closely related species
in the genus Salvelinus. Both species show substantial intra-specific variation in ecology …

Linear and heterogeneous habitat makes headwater stream networks an ideal ecosystem in
which to test the influence of environmental factors on spatial genetic patterns of obligatory …

Freshwater ecosystems are linked at various spatial and temporal scales by movements of
biota adapted to life in water. We review the literature on movements of aquatic organisms …

Many tropical organisms show large genetic differences among populations, yet the
prevalent drivers of the underlying divergence processes are incompletely understood. We …

Habitat fragmentation has become an increasing concern in conservation biology and is of
prime importance with the expansion of forest road networks toward boreal and arctic …

Salmonid populations of many rivers are rapidly declining. One possible explanation is that
habitat fragmentation increases genetic drift and reduces the populations' potential to adapt …

The relationship between the effective number of breeders (N b) and the generational
effective size (N e) has rarely been examined empirically in species with overlap** …

The processes affecting species diversification may also exert an influence on patterns of
genetic variability within species. We evaluated the contributions of five variables potentially …

Conservation management of threatened species requires identifying the landscape
features that shape population structure. Within river ecosystems, the dendritic nature of river …

The identification of landscape or climatic correlates of genetic connectivity can reveal the
processes that regulate spatial diversity and inform the management and conservation of …
