Open AccessMicrobiome and epigenetic variation in wild fish with low genetic diversity
Non-genetic sources of phenotypic variation, such as the epigenome and the microbiome, could be important contributors to adaptive variation for species with low genetic diversity. However, little is known abo...

Open AccessOver 200,000 kilometers of free-flowing river habitat in Europe is altered due to impoundments
European rivers are disconnected by more than one million man-made barriers that physically limit aquatic species migration and contribute to modification of freshwater habitats. Here, a Conceptual Habitat Alt...

Boat ramps facilitate the dispersal of the highly invasive zebra mussel (Dreissena polymorpha)
Invasive bivalves can cause widespread ecological damage, but eradication has proved difficult. Identifying the pathways of dispersal is crucial to implementing more effective biocontainment measures. We exami...

More than one million barriers fragment Europe’s rivers
Rivers support some of Earth’s richest biodiversity1 and provide essential ecosystem services to society2, but they are often fragmented by barriers to free flow3. In Europe, attempts to quantify river connectivi...

More than meets the eye: syntopic and morphologically similar mangrove killifish species show different mating systems and patterns of genetic structure along the Brazilian coast
Different mating systems can strongly affect the extent of genetic diversity and population structure among species. Given the increased effects of genetic drift on reduced population size, theory predicts tha...

Open AccessEffect of artificial barriers on the distribution of the invasive signal crayfish and Chinese mitten crab
The role of river obstacles in preventing or facilitating the dispersal and establishment of aquatic invasive species is controversial. Novel detection tools like environmental DNA (eDNA) can be used for monit...

Open AccessTranscriptomic response to parasite infection in Nile tilapia (Oreochromis niloticus) depends on rearing density
Captive animal populations, be it for food production or conservation programmes, are often maintained at densities far beyond those in natural environments, which can have profound effects on behaviour, immun...

Open AccessTemporal and spatial instability in neutral and adaptive (MHC) genetic variation in marginal salmon populations
The role of marginal populations for the long-term maintenance of species’ genetic diversity and evolutionary potential is particularly timely in view of the range shifts caused by climate change. The Centre-P...

Open AccessPatterns of natural selection acting on the mitochondrial genome of a locally adapted fish species
Mitochondrial DNA (mtDNA) is frequently used in population genetic studies and is usually considered as a neutral marker. However, given the functional importance of the proteins encoded by the mitochondrial g...

The role of founder effects on the genetic structure of the invasive bullfrog (Lithobates catesbeianaus) in China
Founder effects and genetic drift can reduce the genetic diversity and alter the genetic composition of introduced species during the processes of population establishment and spread. Thus, founder effects are...

MHC evolution in three salmonid species: a comparison between class II alpha and beta genes
The genes of the major histocompatibility complex (MHC) are amongst the most variable in vertebrates and represent some of the best candidates to study processes of adaptive evolution. However, despite the num...

Effect of natural selection on the duplicated lysyl oxidase gene in Atlantic salmon
We examined the polymorphism of the lysyl oxidase (LOX) locus, involved in the initiation of muscle collagen cross-linking, in three populations of Atlantic salmon with different life histories and growth rates a...

Fluctuating sex ratios, but no sex-biased dispersal, in a promiscuous fish
Dispersal in birds and mammals tends to be female-biased in monogamous species and male-biased in polygamous species. However results for other taxa, most notably fish, are equivocal. We employed molecular mar...

Asymmetric gene flow and the evolutionary maintenance of genetic diversity in small, peripheral Atlantic salmon populations
Small populations may be expected to harbour less genetic variation than large populations, but the relation between census size (N), effective population size (N e), and genetic diversity...
