Escalating the conflict? Intersex genetic correlations influence adaptation to environmental change in facultatively migratory populations [PDF]
Males and females are often subject to different and even opposing selection pressures. When a given trait has a shared genetic basis between the sexes, sexual conflict (antagonism) can arise.

Whole-Genome Resequencing to Evaluate Life History Variation in Anadromous Migration of Oncorhynchus mykiss [PDF]
Anadromous fish experience physiological modifications necessary to migrate between vastly different freshwater and marine environments, but some species such as Oncorhynchus mykiss demonstrate variation in life history strategies with some individuals ...

Genetic structure of Ponto‐Caspian trout populations shows gene flow among river drainages and supports resident Salmo rizeensis as a genetically distinct taxon [PDF]
To assess the genetic structure of Ponto‐Caspian brown trout (Salmo trutta complex) populations, we analyzed both mitochondrial DNA sequences and genotypes at 10 microsatellite loci of fish caught in the Black Sea and from nine river catchments in ...

Balancing risks and rewards of alternate strategies in the seaward extent, duration and timing of fjord use in contemporary anadromy of brown trout (Salmo trutta) [PDF]
Background Anadromy comprises a successful life-cycle adaptation for salmonids, with marine migration providing improved feeding opportunities and thus improved growth.

Defining Conservation Units in a Highly Diverse Species: A Case on Arctic Charr [PDF]
Defining appropriate conservation units is crucial to the protection and management of biodiversity. These delineations deliver further benefit when they include assessments of population vulnerability to extinction from pressures such as climate change.

Genetic divergence and one‐way gene flow influence contemporary evolution and ecology of a partially migratory fish [PDF]
Recent work has revealed the importance of contemporary evolution in shaping ecological outcomes. In particular, rapid evolutionary divergence between populations has been shown to impact the ecology of populations, communities, and ecosystems.

Adaptation in landlocked Atlantic salmon links genetics in wild and farmed salmon to smoltification [PDF]
Increased knowledge of heritable traits in Atlantic Salmon (Salmo salar) is important to overcome bottlenecks in salmonid aquaculture. Atlantic salmonid populations, both landlocked and anadromous, represent an interesting model to gain insight into ...

Otolith microchemistry and diadromy in Patagonian river fishes [PDF]
Coastal habitats in Chile are hypothesized to support a number of diadromous fish species. The objective of this study was to document migratory life histories of native galaxiids and introduced salmonids from a wide latitudinal range in Chilean ...
