Males and females share many traits that have a common genetic basis; however, selection on these traits often differs between the sexes, leading to sexual conflict. Under such sexual antagonism, theory predicts the evolution of genetic architectures that resolve this sexual conflict. Yet, despite intense theoretical and empirical interest, the specific loci underlying sexually antagonistic phenotypes have rarely been identified, limiting our understanding of how sexual conflict impacts genome evolution and the maintenance of genetic...
Data from: Genome-wide analyses suggest parallel selection for universal traits may eclipse local environmental selection in a highly mobile carnivoreAstrid Vik Stronen, Bogumiła Jędrzejewska, Cino Pertoldi, Ditte Demontis, Ettore Randi, Magdalena Niedziałkowska, Tomasz Borowik, Vadim E.

Ecological and environmental heterogeneity can produce genetic differentiation in highly mobile species. Accordingly, local adaptation may be expected across comparatively short distances in the presence of marked environmental gradients. Within the European continent, wolves (Canis lupus) exhibit distinct north–south population differentiation. We investigated more than 67-K single nucleotide polymorphism (SNP) loci for signatures of local adaptation in 59 unrelated wolves from four previously identified population clusters (northcentral Europe n = 32, Carpathian Mountains n =...
While pathogens are often assumed to limit the growth of wildlife populations, experimental evidence for their effects is rare. A lack of food resources has been suggested to enhance the negative effects of pathogen infection on host populations, but this theory has received little investigation. We conducted a replicated two-factor enclosure experiment, with introduction of the bacterium Bordetella bronchiseptica and food supplementation, to evaluate the individual and interactive effects of pathogen infection and food availability...
Data from: Low but significant genetic differentiation underlies biologically meaningful phenotypic divergence in a large Atlantic salmon populationTutku Aykanat, Susan E. Johnston, Eero Niemelä, Panu Orell, Jaakko Erkinaro & Craig R. Primmer
Despite decades of research assessing the genetic structure of natural populations, the biological meaning of low yet significant genetic divergence often remains unclear due to a lack of associated phenotypic and ecological information. At the same time, structured populations with low genetic divergence and overlapping boundaries can potentially provide excellent models to study adaptation and reproductive isolation in cases where high-resolution genetic markers and relevant phenotypic and life history information are available. Here, we combined...
Data from: Enriched rearing environment and wild genetic background can enhance survival and disease resistance of salmonid fishes during parasite epidemicsAnssi Karvonen, Mariella Aalto-Araneda, Anna-Maija Virtala, Raine Kortet, Perttu Koski & Pekka Hyvärinen
The importance and volume of aquaculture is increasing world-wide. Rearing practices play a key role in determining growth rate, survival and disease resistance in aquaculture fishes. Recent evidence suggests that in comparison with a standard stimulus-poor rearing environment, an enriched or variable rearing environment has significant positive effects on several traits underlying growth and well-being of fish. However, the effect of enriched rearing on one of the most important threats for aquaculture development, occurrence of...
Data from: The contemporary genetic pattern of European moose is shaped by postglacial recolonization, bottlenecks, and the geographical barrier of the Baltic SeaMagdalena Niedziałkowska, Kris J. Hundertmark, Bogumiła Jędrzejewska, Vadim E. Sidorovich, Hanna Zalewska, Rauno Veeroja, Erling J. Solberg, Sauli Laaksonen, Håkan Sand, Vyacheslav A. Solovyev, Andrey Sagaydak, Juha Tiainen, Rimvydas Juškaitis, Gundega Done, Vadim A. Borodulin, Evgenii A. Tulandin & Krzysztof Niedziałkowski
To investigate genetic diversity and the population structure of the European moose (Alces alces), we analyzed 14 microsatellite loci for 694 samples collected across 16 localities. The highest genetic diversity was detected in Belarus and Russia and the lowest was found in Scandinavia. Two major genetic clusters existed, Scandinavian and continental, and some further spatial structure was detected. There was high concordance between the spatial distribution of microsatellite clusters analyzed in the present study and...
Data from: Inter-annual variation and long-term trends in proportions of resident individuals in partially migratory birdsKalle Meller, Anssi V Vähätalo, Tatu Hokkanen, Jukka Rintala, Markus Piha & Aleksi Lehikoinen
Partial migration – a part of a population migrates and another part stays resident year-round on the breeding site – is probably the most common type of migration in the animal kingdom, yet it has only lately garnered more attention. Theoretical studies indicate that in partially migratory populations, the proportion of resident individuals (PoR) should increase in high latitudes in response to the warming climate, but empirical evidence exists for few species. We provide the...
Data from: What data to use for forest conservation planning? A comparison of coarse open and detailed proprietary forest inventory data in FinlandJoona A. Lehtomäki, Sakari Tuominen, Tuuli Toivonen, Antti Leinonen & Joona Lehtomäki
The boreal region is facing intensifying resource extraction pressure, but the lack of comprehensive biodiversity data makes operative forest conservation planning difficult. Many countries have implemented forest inventory schemes and are making extensive and up-to-date forest databases increasingly available. Some of the more detailed inventory databases, however, remain proprietary and unavailable for conservation planning. Here, we investigate how well different open and proprietary forest inventory data sets suit the purpose of conservation prioritization in Finland....
