Data from: Gene flow from domesticated escapes alters the life history of wild Atlantic salmon

Geir H. Bolstad, Kjetil Hindar, Grethe Robertsen, Bror Jonsson, Harald Sægrov, Ola H. Diserud, Peder Fiske, Arne J. Jensen, Kurt Urdal, Tor F. Næsje, Bjørn T. Barlaup, Bjørn Florø-Larsen, Håvard Lo, Eero Niemelä & Sten Karlsson
Interbreeding between domesticated and wild animals occurs in several species. This gene flow has long been anticipated to induce genetic changes in life-history traits of wild populations, thereby influencing population dynamics and viability. Here, we show that individuals with high levels of introgression (domesticated ancestry) have altered age and size at maturation in 62 wild Atlantic salmon Salmo salar populations, including seven ancestral populations to breeding lines of the domesticated salmon. This study documents widespread...

Data from: Taxon abundance, diversity, co-occurrence and network analysis of the ruminal microbiota in response to dietary changes in dairy cows

Ilma Tapio, Daniel Fischer, Lucia Blasco, Miika Tapio, R. John Wallace, Ali R. Bayat, Laura Ventto, Minna Kahala, Enyew Negussie, Kevin J. Shingfield & Johanna Vilkki
The effects of sunflower oil (SO) (0 or 50 g/kg diet dry matter), supplemented to diets contrasting in the proportion of forage and concentrate (FC) (65:35 vs 35:65), were evaluated for their influence on rumen microbiome. Four multiparous Nordic Red dairy cows fitted with rumen cannulae were used in a 4 × 4 Latin square with a 2 × 2 factorial arrangement of treatments and four 35-d periods. Ruminal digesta samples were collected on d...

Data from: Pulse of inflammatory proteins in the pregnant uterus of European polecats (Mustela putorius) leading to the time of implantation

Heli Lindeberg, Richard J.S. Burchmore, Malcolm W. Kennedy & Richard J. S. Burchmore
Uterine secretory proteins protect the uterus and conceptuses against infection, facilitate implantation, control cellular damage resulting from implantation, and supply pre-implantation embryos with nutrients. Unlike in humans, the early conceptus of the European polecat (Mustela putorius; ferret) grows and develops free in the uterus until implanting at about 12 days after mating. We found that the proteins appearing in polecat uteri changed dramatically with time leading to implantation. Several of these proteins have also been...

Data from: Spatio-temporal dynamics of a fish predator: density-dependent and hydrographic effects on Baltic Sea cod population

Valerio Bartolino, Huidong Tian, Ulf Bergström, Pekka Jounela, Eero Aro, Christian Dieterich, H.E. Markus Meier, Massimiliano Cardinale, Barbara Bland, Michele Casini & H. E. Markus Meier
Understanding the mechanisms of spatial population dynamics is crucial for the successful management of exploited species and ecosystems. However, the underlying mechanisms of spatial distribution are generally complex due to the concurrent forcing of both density-dependent species interactions and density-independent environmental factors. Despite the high economic value and central ecological importance of cod in the Baltic Sea, the drivers of its spatio-temporal population dynamics have not been analytically investigated so far. In this paper, we...

Data from: Genetic substructure and admixture as important factors in linkage disequilibrium-based estimation of effective number of breeders in recovering wildlife populations

Alexander Kopatz, Hans Geir Eiken, Julia Schregel, Jouni Aspi, Ilpo Kojola & Snorre B. Hagen
The number of effective breeders (Nb) and effective population size (Ne) are population parameters reflective of evolutionary potential, susceptibility to stochasticity, and viability. We have estimated these parameters using the linkage disequilibrium-based approach with LDNE through the latest phase of population recovery of the brown bears (Ursus arctos) in Finland (1993–2010; N = 621). This phase of the recovery was recently documented to be associated with major changes in genetic composition. In particular, differentiation between...

Data from: Integrating genetic analysis of mixed populations with a spatially-explicit population dynamics model

Rebecca Whitlock, Samu Mäntyniemi, Stefan Palm, Marja-Liisa Koljenen, Johan Dannewitz, Johan Östergren & Marja-Liisa Koljonen
Inferring the dynamics of populations in time and space is a central challenge in ecology. Intra-specific structure (for example genetically distinct sub-populations or meta-populations) may require methods that can jointly infer the dynamics of multiple populations. This is of particular importance for harvested species, for which management must balance utilization of productive populations with protection of weak ones. Here we present a novel method for simultaneous learning about the spatio-temporal dynamics of multiple populations that...

Data from: Do environmental conditions experienced in early life affect recruitment age and performance at first breeding in common goldeneye females?

Hannu Pöysä, Robert G. Clark, Antti Paasivaara & Pentti Runko
Environmental conditions experienced early in life may have long-term impacts on life history traits and reproductive performance. We investigated whether ambient temperature experienced during the first two to four weeks of life and weather severity during the first two winters affected recruitment age and relative timing of breeding in the year of recruitment in female common goldeneyes (Bucephala clangula). Our sample consisted of 141 female recruits hatched in a study population in central Finland between...

Data from: Oxygen and carbon isoscapes for the Baltic Sea: testing their applicability in fish migration studies

Jyrki Torniainen, Anssi Lensu, Pekka J. Vuorinen, Eloni Sonninen, Marja Keinänen, Roger I. Jones, William P. Patterson & Mikko Kiljunen
Conventional tags applied to individuals have been used to investigate animal movement, but these methods require tagged individuals be recaptured. Maps of regional isotopic variability known as “isoscapes” offer potential for various applications in migration research without tagging wherein isotope values of tissues are compared to environmental isotope values. In this study, we present the spatial variability in oxygen (math formula) and dissolved inorganic carbon (δ13CDIC) isotope values of Baltic Sea water. We also provide...

Data from: Socio-economic impact classification of alien taxa (SEICAT)

Martinou, Wolfgang Nentwig, Jan Pergl, Petr Pyšek, Wolfgang Rabitsch, David M. Richardson, Helen E. Roy, Wolf-Christian Saul, Riccardo Scalera, Montserrat Vila, John R. U. Wilson, Sabina Kumschick & Sabrina Kumschick
Many alien taxa are known to cause socio-economic impacts by affecting the different constituents of human well-being (security; material and non-material assets; health; social, spiritual and cultural relations; freedom of choice and action). Attempts to quantify socio-economic impacts in monetary terms are unlikely to provide a useful basis for evaluating and comparing impacts of alien taxa because they are notoriously difficult to measure and important aspects of human well-being are ignored. Here, we propose a...
