Effective population size (Ne) determines the strength of genetic drift in a population and has
long been recognized as an important parameter for evaluating conservation status and …

More than a century of impoundments in the Penobscot River, Maine, USA, has contributed
to population declines in migratory fish in the system. A decade of change, research, and …

The imminent demise of montane species is a recurrent theme in the climate change
literature, particularly for aquatic species that are constrained to networks and elevational …

Dams and other anthropogenic barriers have caused global ecological and hydrological
upheaval in the blink of the geological eye. In the present article, we synthesize 307 studies …

Artificial barriers are one of the main threats to river ecosystems, resulting in habitat
fragmentation and loss of connectivity. Yet, the abundance and distribution of most artificial …

The evolutionary mechanisms generating the tremendous biodiversity of islands have long
fascinated evolutionary biologists. Genetic drift and divergent selection are predicted to be …

Anthropogenic climate change is warming global temperatures, with significant implications
for salmonid fishes that depend on the availability of cold water during one or more life …

Habitat loss and fragmentation often result in small, isolated populations vulnerable to
environmental disturbance and loss of genetic diversity. Low genetic diversity can increase …

Spatial population structure plays an important role in species persistence, evolution and
conservation. Benthic stream fishes are diverse and frequently imperilled, yet the …

We tested the relative influence of habitat patch size and connectivity on genetic structure
and effective population size in eight brook trout (Salvelinus fontinalis) habitat patches in a …
