Unravelling the factors shaping the genetic structure of mobile marine species is challenging due to the high potential for gene flow. However, genetic inference can be greatly enhanced by increasing the genomic, geographic or environmental resolution of population genetic studies. Here we investigated the population structure of turbot (Scophthalmus maximus) by screening 17 random and gene-linked markers in 999 individuals at 290 geographical locations throughout the Northeast Atlantic Ocean. A seascape genetics approach with the...

Data from: The importance of social dimension and maturation stage for the probabilistic maturation reaction norm in Poecilia reticulata

Beatriz Diaz Pauli & Mikko Heino
Maturation is an important event in an organism's life history, with important implications on dynamics of both wild and captive populations. The probabilistic maturation reaction norm (PMRN) has emerged as an important method to describe variation in maturation in wild fish. Because most PMRNs are based on age and size only, it is important to understand limitations of these variables in explaining maturation. We experimentally assessed (i) the sensitivity of age- and size-based PMRNs to...

Data from: A genomic island linked to ecotype divergence in Atlantic cod

Jakob Hemmer-Hansen, Einar E. Nielsen, Nina O. Therkildsen, Martin I. Taylor, Rob Ogden, Audrey J. Geffen, Dorte Bekkevold, Sarah Helyar, Christophe Pampoulie, Torild Johansen & Gary R. Carvalho
The genomic architecture underlying ecological divergence and ecological speciation with gene flow is still largely unknown for most organisms. One central question is whether divergence is genome-wide or localized in “genomic mosaics” during early stages when gene flow is still pronounced. Empirical work has so far been limited, and the relative impacts of gene flow and natural selection on genomic patterns have not been fully explored. Here, we use ecotypes of Atlantic cod to investigate...

Data from: Taxonomy, biogeography and DNA barcodes of Geodia species (Porifera, Demospongiae, Tetractinellida) in the Atlantic boreo-arctic region

Paco Cárdenas, Hans Tore Rapp, Anne Birgitte Klitgaard, Megan Best, Mikael Thollesson & Ole Secher Tendal
Geodia species north of 60°N in the Atlantic appeared in the literature for the first time when Bowerbank described Geodia barretti and G. macandrewii in 1858 from western Norway. Since then, a number of species have been based on material from various parts of the region: G. simplex, Isops phlegraei, I. pallida, I. sphaeroides, Synops pyriformis, G. parva, G. normani, G. atlantica, Sidonops mesotriaena (now called G. hentscheli), and G. simplicissima. In addition to these...

Data from: Evolutionary origin of the Scombridae (tunas and mackerels): members of a Paleogene adaptive radiation with 14 other pelagic fish families

Masaki Miya, Matt Friedman, Takashi P. Satoh, Hirohiko Takeshima, Tetsuya Sado, Wataru Iwasaki, Yusuke Yamanoue, Masanori Nakatani, Kohji Mabuchi, Jun G. Inoue, Jan Yde Poulsen, Tsukasa Fukunaga, Yukuto Sato & Mutsumi Nishida
Uncertainties surrounding the evolutionary origin of the epipelagic fish family Scombridae (tunas and mackerels) are symptomatic of the difficulties in resolving suprafamilial relationships within Percomorpha, a hyperdiverse teleost radiation that contains approximately 17,000 species placed in 13 ill-defined orders and 269 families. Here we find that scombrids share a common ancestry with 14 families based on (i) bioinformatic analyses using partial mitochondrial and nuclear gene sequences from all percomorphs deposited in GenBank (10,733 sequences) and...

Data from: A molecular gut content study of Themisto abyssorum (Amphipoda) from Arctic hydrothermal vent and cold seep systems

Bernt Rydland Olsen, Christofer Troedsson, Kenan Hadziavdic, Hans Tore Rapp & Rolf B. Pedersen
The use of DNA as a marker for prey inside the gut of predators has been instrumental in further understanding of known and unknown interactions. Molecular approaches are in particular useful in unavailable environments like the deep-sea. Trophic interactions in the deep-sea are difficult to observe in situ, correct deep-sea experimental laboratory conditions are difficult to obtain, animals rarely survive the sampling, or the study organisms feed during the sampling due to long hauls. Preliminary...

Data from: Next-generation sequencing for molecular ecology: a caveat regarding pooled samples

Eric C. Anderson, Hans J. Skaug & Daniel J. Barshis
We develop a model based on the Dirichlet-compound multinomial distribution (CMD) and Ewens sampling formula to predict the fraction of SNP loci that will appear fixed for alternate alleles between two pooled samples drawn from the same underlying population. We apply this model to next-generation sequencing (NGS) data from Baltic Sea herring recently published by (Corander et al., , Molecular Ecology, 2931–2940), and show that there are many more fixed loci than expected in the...

Data from: Attitudes towards smoking restrictions and tobacco advertisement bans in Georgia

George D. Bakhturidze, Maurice B. Mittelmark, Leif E. Aarø & Nana T. Peikrishvili
BACKGROUND: The level of public support for restrictions on tobacco use is an important element in a nation’s response to the need for tobacco control. However, no data have been available from Georgia on public opinion regarding smoking restrictions in public places, and on bans on tobacco advertisement, sponsorship and promotion. METHODS: 1,588 respondents aged 13-70 were interviewed at home about their level of agreement with eight possible smoking restrictions, used to calculate a dichotomous...

Data from: Outlier SNP markers reveal fine-scale genetic structuring across European hake populations (Merluccius merluccius)

Ilaria Milano, Massimiliano Babbucci, Alessia Cariani, Miroslava Atanassova, Dorte Bekkevold, Gary R. Carvalho, Montserrat Espiñeira, Fabio Fiorentino, Germana Garofalo, Audrey J. Geffen, Einar E. Nielsen, Rob Ogden, Tomaso Patarnello, Marco Stagioni, Fausto Tinti & Luca Bargelloni
Shallow population structure is generally reported for most marine fish and explained as a consequence of high dispersal, connectivity and large population size. Targeted gene analyses and more recently genome-wide studies have challenged such view, suggesting that adaptive divergence might occur even when neutral markers provide genetic homogeneity across populations. Here, 381 SNPs located in transcribed regions were used to assess large- and fine-scale population structure in the European hake (Merluccius merluccius), a widely distributed...
