Summary Parasites and pathogens can have an important effect on their host's thermal resistance. The impact of parasite infection host physiological performances has traditionally been studied in controlled laboratory conditions, much less is known about its actual effects wild populations. Nonetheless, such knowledge critical when assessing the climate change future survival host.

Abstract Many salmonid fish populations are threatened by genetic homogenization, primarily due to introgressive hybridization with hatchery‐reared conspecifics. By applying genomewide analysis using two molecular marker types (1986 SNP s and 17 microsatellites), we assessed the impacts of inadvertent gene flow via straying from hatchery releases on wild Atlantic salmon in Gulf Finland, Baltic Sea, over 16 years (1996–2012). Both microsatellites revealed congruent population structuring,...

Domesticated/captive stocks and wild/feral populations of common carp from Europe, Central Asia East/South-East were examined for allozyme (23 populations), microsatellite (11 populations) mitochondrial DNA (21 variation. Allozyme variability (1.06–1.81 alleles per locus, expected heterozygosity 0.006–0.136 at 16 loci) was much lower than (2.5–14.0 0.426–0.887 four loci). Differences in between domesticated/captive wild-caught ones more pronounced loci loci, suggesting that microsatellites...

Abstract Mitochondrial and microsatellite DNA markers were applied to infer the phylogeography, intraspecific diversity dynamics of distributional history European grayling ( Thymallus thymallus ) with focus on its central northern distribution range. Phylogenetic nested clade analyses revealed at least four major mtDNA lineages, which evolved in geographical isolation during Pleistocene. These lineages should be recognized as basic evolutionary significant units (ESUs) for Europe. In...

The genetic structure and phylogeography of Atlantic salmon (Salmo salar) across the Baltic Sea basin neighbouring areas (eastern Ocean, North Sea, Barents White two Russian lakes, Onega Ladoga) were studied to resolve partly contradictory hypotheses species' postglacial colonization history. Thirty-eight populations (total 2180 individuals) for nine DNA microsatellite loci.

For decades, linkage mapping has been one of the most powerful and widely used approaches for elucidating genetic architecture phenotypic traits medical, agricultural evolutionary importance. However, successful Mendelian quantitative depends critically on availability fast preferably high-throughput genotyping platforms. Several array-based single nucleotide polymorphism (SNP) platforms have developed model organisms during recent years but these methods become prohibitively expensive...

Health after pathogen contact varies among individuals because of differences in load (which is limited by resistance) and disease severity response to tolerance). To understand pathogen-induced host evolution, it critical know not only the relative contributions nongenetic genetic variation resistance tolerance but also how they change environmentally. We quantified parasite associated temperature-dependent trout siblings from two rivers. detected a variance for 6.6 times as large colder...

Over the recent years, growing number of studies suggests that intensive size-selective fishing can cause evolutionary changes in life-history traits harvested population, which have drastic negative effects on populations, ecosystems and fisheries. However, most to date overlooked potential role immigration fish with different phenotypes as an alternative plausible mechanism behind observed phenotypic trends. Here, we investigated consequences simultaneously at molecular level Eurasian...

The Eurasian perch (Perca fluviatilis) is the most common fish of Percidae family and widely distributed across Eurasia. Perch a popular target for professional recreational fisheries, promising freshwater aquaculture species in Europe. However, despite its high ecological, economical societal importance, available genomic resources P. fluviatilis are rather limited. In this work, we report de novo assembly annotation whole genome sequence perch. linked-read based technology with 10X...

Albinism is a widespread departure from typical body colouration due to altered melanin production. The Wels catfish (Silurus glanis) among the largest freshwater fish species in world, and albino individuals occur both wild aquaculture. Here, we performed transcriptome-wide analysis of normally pigmented S. glanis using four tissues (skin, dorsal fin, whole eye liver) identify genes associated with albinism by exploring patterns differential expression (DE) alternative splicing (DAS)....

Parasites often occupy specific sites within their host, which has important implications for host performance and parasite transmission. Nonetheless, parasitic infections can occur beyond typical location a significantly altering host-parasite interactions. Yet, the causes behind atypical tissue tropism are poorly understood. Here, we focus on ubiquitous group of diplostomid parasites that form diverse communities in fish eyes. We used targeted DNA metabarcoding (cytochrome c oxydase...

Abstract European grayling, Thymallus thymallus (L.), populations have steadily declined since the mid‐1980s, mostly because of habitat degradation and increased predation pressure.

Over last decade, several studies investigated phylogeography population genetic structure T. using mitochondrial nuclear microsatellite DNA markers. However, no study has covered distribution range...

ABSTRACT How genetic variation contributes to adaptation at different environments is a central focus in evolutionary biology. However, most free‐living species still lack comprehensive understanding of the primary molecular mechanisms adaptation. Here, we characterised targets selection associated with drastically aquatic environments—humic and clear water—in common freshwater fish, Eurasian perch ( Perca fluviatilis ). By using whole‐genome sequencing (WGS) on large population dataset n =...
