Data from: Population genomic analyses of early phase Atlantic salmon (Salmo salar) domestication/captive breeding.

Hannu Mäkinen, Anti Vasemägi, Philip McGinnity, Tom F. Cross, Craig Primmer & Craig R. Primmer
Domestication can have adverse genetic consequences, which may reduce the fitness of individuals once released back into the wild. Many wild Atlantic salmon (Salmo salar L.) populations are threatened by anthropogenic influences and they are supplemented with captively bred fish. The Atlantic salmon is also widely used in selective breeding programs to increase the mean trait values for desired phenotypic traits. We analyzed a genome-wide set of SNPs in three domesticated Atlantic salmon strains and...

Data from: Avian top predator and the landscape of fear: responses of mammalian mesopredators to risk imposed by the golden eagle

Mari S. Lyly, Alexandre Villers, Elina Koivisto, Pekka Helle, Tuomo Ollila & Erkki Korpimäki
Top predators may induce extensive cascading effects on lower trophic levels, for example, through intraguild predation (IGP). The impacts of both mammalian and avian top predators on species of the same class have been extensively studied, but the effects of the latter upon mammalian mesopredators are not yet as well known. We examined the impact of the predation risk imposed by a large avian predator, the golden eagle (Aquila chrysaetos, L.), on its potential mammalian...

Data from: Early reproductive investment, senescence and lifetime reproductive success in female Asian elephants

Adam D. Hayward, Khyne U. Mar, Mirkka Lahdenperä & Virpi Lummaa
The evolutionary theory of senescence posits that as the probability of extrinsic mortality increases with age, selection should favour early-life over late-life reproduction. Studies on natural vertebrate populations show early reproduction may impair later-life performance, but the consequences for lifetime fitness have rarely been determined, and little is known of whether similar patterns apply to mammals which typically live for several decades. We used a longitudinal dataset on Asian elephants (Elephas maximus) to investigate associations...

Data from: The evolutionary history of Afrocanarian blue tits inferred from genome-wide SNPs

Jostein Gohli, Erica Leder, Eduardo Garcia-Del-Rey, Lars Erik Johannessen, Arild Johnsen, Terje Laskemoen, Magnus Popp, Jan T. Lifjeld & Erica H. Leder
A common challenge in phylogenetic reconstruction is to find enough suitable genomic markers to reliably trace splitting events with short internodes. Here we present phylogenetic analyses based on genome-wide single-nucleotide polymorphisms (SNPs) of an enigmatic avian radiation, the subspecies complex of Afrocanarian blue tits (Cyanistes teneriffae). The two sister species, the Eurasian blue tit (Cyanistes caeruleus) and the azure tit (Cyanistes cyanus), constituted the outgroup. We generated a large data set of SNPs for analysis...

Data from: Preference for outbred host plants and positive effects of inbreeding on egg survival in a specialist herbivore

Aino Kalske, Anne Muola, Pia Mutikainen & Roosa Leimu
Inbreeding can profoundly affect the interactions of plants with herbivores as well as with the natural enemies of the herbivores. We studied how plant inbreeding affects herbivore oviposition preference, and whether inbreeding of both plants and herbivores alters the probability of predation or parasitism of herbivore eggs. In a laboratory preference test with the specialist herbivore moth Abrostola asclepiadis and inbred and outbred Vincetoxicum hirundinaria plants, we discovered that herbivores preferred to oviposit on outbred...

Data from: Heterospecific female mimicry in Ficedula flycatchers

Sara Calhim, Peter Adamík, Pauliina Järvistö, Paula Leskinen, János Török, Kazumasa Wakamatsu & Toni Laaksonen
Mimicry is a widespread phenomenon. Vertebrate visual mimicry often operates in an intraspecific sexual context, with some males resembling conspecific females. Pied flycatcher (Ficedula hypoleuca) dorsal plumage varies from the ancestral black to female-like brown. Experimental studies have shown that conspecific and heterospecific (collared flycatcher, F. albicollis) individuals of both sexes respond, at least initially, to brown individuals as if they were female. We quantified the perceptual and biochemical differences between brown feathers and found...

Data from: Genome-wide SNP analysis reveals a genetic basis for sea-age variation in a wild population of Atlantic salmon (Salmo salar)

Susan E. Johnston, Panu Orell, Victoria L. Pritchard, Matthew P. Kent, Sigbjørn Lien, Eero Niemelä, Jaakko Erkinaro, Craig Primmer & Craig R. Primmer
Delaying sexual maturation can lead to larger body size and higher reproductive success, but carries an increased risk of death before reproducing. Classical life history theory predicts that trade-offs between reproductive success and survival should lead to the evolution of an optimal strategy in a given population. However, variation in mating strategies generally persists, and in general, there remains a poor understanding of genetic and physiological mechanisms underlying this variation. One extreme case of this...

Data from: Gene expression plasticity evolves in response to colonization of freshwater lakes in threespine stickleback

Matthew R. J. Morris, Romain Richard, Erica H. Leder, Rowan D. H. Barrett, Nadia Aubin-Horth & Sean M. Rogers
Phenotypic plasticity is predicted to facilitate individual survival and/or evolve in response to novel environments. Plasticity that facilitates survival should both permit colonization and act as a buffer against further evolution, with contemporary and derived forms predicted to be similarly plastic for a suite of traits. On the other hand, given the importance of plasticity in maintaining internal homeostasis, derived populations that encounter greater environmental heterogeneity should evolve greater plasticity. We tested the evolutionary significance...

Data from: Are statin trials in diabetes representative of real-world diabetes care: a population-based study on statin initiators in Finland

Päivi Ruokoniemi, Reijo Sund, Martti Arffman, Arja Helin-Salmivaara, Risto Huupponen, Ilmo Keskimaki, Tuulikki Vehko & Maarit Korhonen
Objective: To assess the representativeness of the Heart Protection Study (HPS) and the Collaborative Atorvastatin Diabetes Study (CARDS) for incident statin users. Design: A population based analysis with linked register data. Setting: Finland. Population: 56 963 diabetic patients initiating statin use in 2005 to 2008. Main outcome measures: We determined the proportions of real-world patients who fulfilled the eligibility criteria for HPS and CARDS trials and assessed the cardiovascular disease (CVD) event rates, assumed to...

Data from: Background matching ability and the maintenance of a colour polymorphism in the red devil cichlid

William Sowersby, Topi K. Lehtonen, Bob B.M. Wong & B. B. M. Wong
The evolution and maintenance of colour polymorphisms remains a topic of considerable research interest. One key mechanism thought to contribute to the coexistence of different colour morphs is a bias in how conspicuous they are to visual predators. Although individuals of many species camouflage themselves against their background to avoid predation, differently coloured individuals within a species may vary in their capacity to do so. However, to date, very few studies have explicitly investigated the...

Data from: Cross-cultural variation in men’s preference for sexual dimorphism in women’s faces

Mikhail V. Kozlov, Huajian Cai, Jorge Contreras-Garduño, Barnaby J. Dixson, Gavita A. Oana, Gwenaël Kaminski, Norman P. Li, Minna T. Lyons, Ike E. Onyishi, Keshav Prasai, Farid Pazhoohi, Pavol Prokop, Sandra L. Rosales Cardozo, Nicolle Sydney, Jose C. Yong, Markus J. Rantala, U. M. Marcinkowska & J. Contreras-Garduno
Both attractiveness judgements and mate preferences vary considerably cross-culturally. We investigated whether men's preference for femininity in women's faces varies between 28 countries with diverse health conditions by analysing responses of 1972 heterosexual participants. Although men in all countries preferred feminized over masculinized female faces, we found substantial differences between countries in the magnitude of men's preferences. Using an average femininity preference for each country, we found men's facial femininity preferences correlated positively with the...

Data from: Predator–vole interactions in northern Europe: the role of small mustelids revised

Katri Korpela, Pekka Helle, Heikki Henttonen, Erkki Korpimäki, Esa Koskela, Otso Ovaskainen, Hannu Pietiäinen, Janne Sundell, Jari Valkama, Otso Huitu, H. Pietiainen & E. Korpimaki
The cyclic population dynamics of vole and predator communities is a key phenomenon in northern ecosystems, and it appears to be influenced by climate change. Reports of collapsing rodent cycles have attributed the changes to warmer winters, which weaken the interaction between voles and their specialist subnivean predators. Using population data collected throughout Finland during 1986–2011, we analyse the spatio-temporal variation in the interactions between populations of voles and specialist, generalist and avian predators, and...

Data from: Consensus RDA across dissimilarity coefficients for canonical ordination of community composition data

F. Guillaume Blanchet, Pierre Legendre, J. A. Colin Bergeron & Fangliang He
Understanding how habitat structures species assemblages in a community is one of the main goals of community ecology. To relate community patterns to particular factors defining habitat conditions, ecologists often use canonical ordinations such as canonical redundancy analysis (RDA). It is a common practice to use dissimilarity coefficients to perform canonical ordinations through distance-based RDA (db-RDA) or transformation-based RDA (tb-RDA). Dissimilarity coefficients are measures of resemblance where the information about species communities is condensed into...
