Stomach content, biomass, abundance and body score of long-tailed ducks (Clangula hyemalis) from south-eastern Baltic Sea
<p>The long-tailed duck (<em>Clangula hyemalis</em>) is a vulnerable and declining species wintering in the Baltic Sea. The introduction of the invasive fish, the round goby (<em>Neogobius melanostomus</em>), dramatically impacted the benthic macrofauna in hard-bottom, while no significant changes occurred in soft-bottom benthic macrofauna. Therefore, we aimed to assess the extent to which the diet of long-tailed duck changed in two different bottom types. We analysed the stomach content of 251 long-tailed ducks bycaught in gillnets from 2016 to 2020 in hard- and soft-bottom habitats and compared these results with those published by Žydelis and Ruškyte (2005). The results show that the long-tailed duck experienced a change in diet in hard-bottom habitats, shifting from the blue mussel to Hediste diversicolor, barnacles and fish. In soft-bottom habitats, their diet remained similar over time and was based on H. diversicolor, a few bivalve species and Saduria entomon. There was no evidence of significant differences in diet neither between sex nor age. Despite the above-mentioned changes in diet, the average body condition of the species did not change neither over time nor between habitats. This confirms that long-tailed ducks have high feeding flexibility and quick species response to changes in prey availability, as they are capable of shifting their diet to new prey.</p>

Genome-wide signatures of synergistic epistasis during parallel adaptation in a Baltic Sea copepod
<p>The role of epistasis in adaptive evolution has remained an unresolved problem dating back to the Evolutionary Synthesis. This role is now being revisited due to its relevance for polygenic adaptation. In the absence of epistasis, polygenic adaptation is predicted to result in non-parallel evolution, because repeated selection could act on subsets of effectively redundant alleles. However, positive epistatic interactions among adaptive alleles would make the alleles non-redundant and selection for particular allelic combinations could drive parallel evolution. The inability to address this fundamental question might arise from traditional approaches lacking the power to capture the genomic architecture and dynamics of polygenic adaptation. To address this problem, we employed a replicated and controlled evolution experiment using the copepod <em>Eurytemora affinis</em> to elucidate the evolutionary response architecture to rapid salinity decline, a predicted consequence of global climate change in higher latitudes. Based on time-resolved pooled whole-genome sequencing, we uncovered a remarkably parallel response, despite polygenic adaptation involving over 1000 loci across ten replicate selection lines. Interestingly, single-nucleotide polymorphism (SNP) frequencies converged during the experiment, far beyond expectations, resulting in replicate lines sharing 93.1% of selected alleles. Using simulations, we found that this polygenic parallelism was consistent with synergistic epistasis among alleles responding in concert across replicate lines, a phenomenon that may be common for selection on complex physiological traits. Furthermore, we found that the same SNPs with signatures of selection in the laboratory also exhibited signatures of selection across a natural salinity gradient in the Baltic Sea. Our study provides the first experimental evidence that polygenic adaptation can actually be highly repeatable at the genomic level, given the presence of synergistic epistasis among the loci under selection.</p>
