Data from: Interspecific interactions and learning variability jointly drive geographic differences in mate preferences

Machteld N. Verzijden & Erik I. Svensson
Co-occurrence of closely related species can cause behavioral interference in mating and increase hybridization risk. Theoretically, this could lead to the evolution of more species-specific mate preferences and sexual signaling traits. Alternatively, females can learn to reject heterospecific males, to avoid male sexual interference from closely related species. Such learned mate discrimination could also affect conspecific mate preferences if females generalize from between species differences to prefer more species-specific mating signals. Female damselflies of the...

Data from: Good reasons to leave home: proximate dispersal cues in a social spider

Reut Berger-Tal, Na'ama Berner Aharon, Shlomi Aharon, Cristina Tuni & Yael Lubin
Natal dispersal is a successful tactic under a range of conditions in spite of significant costs. Habitat quality is a frequent proximate cause of dispersal, and studies have shown that dispersal increases both when natal habitat quality is good or poor. In social species kin competition, favoring dispersal, may be balanced by the benefits of group living, favoring philopatry. We investigated the effect of changes in the local environment on natal dispersal of adult females...

Data from: Region-wide and ecotype-specific differences in demographic histories of threespine stickleback populations, estimated from whole genome sequences

Shenglin Liu, Michael M. Hansen & Magnus W. Jacobsen
We analysed 81 whole genome sequences of threespine sticklebacks from Pacific North America, Greenland and Northern Europe, representing 16 populations. Principal component analysis of nuclear SNPs grouped populations according to geographical location, with Pacific populations being more divergent from each other relative to European and Greenlandic populations. Analysis of mitogenome sequences showed Northern European populations to represent a single phylogeographical lineage, whereas Greenlandic and particularly Pacific populations showed admixture between lineages. We estimated demographic history...

Data from: The association between exposure to environmental bisphenol A and gonadotropic hormone levels among men

Hong Liang, Wenping Xu, Jianping Chen, Huijuan Shi, Jiang Zhu, Xiaoqin Liu, Jian Wang, Maohua Miao & Wei Yuan
Bisphenol A (BPA) is an extensively used chemical with endocrine disrupting properties. Although animal and in vivo studies have suggested possible effects of BPA on levels of gonadotropic hormones, human studies are limited and inconclusive. The study examined whether environmental BPA exposure was associated with gonadotropic hormones levels in men. A total of 560 men aged 18–55 years were recruited from Sandu County, Guizhou Province, China. We collected urine samples for measurement of BPA, and...

Data from: A new paradigm for biomonitoring: an example building on the Danish Stream Plant Index

Annette Baattrup-Pedersen, Emma Göthe, Tenna Riis, Dagmar K. Andersen & Søren E. Larsen
Despite intensive efforts for more than a decade to develop Water Framework-compliant assessment systems, shortcomings continue to appear. In particular, the lack of reference conditions has hindered the development of assessment systems capturing the heart of the Water Framework Directive (WFD) – that ecological status should be set as the deviation from the natural, undisturbed condition. Recently, the Danish Stream Plant Index (DSPI) was developed. This system contrasts existing systems in that it builds on...

Data from: Patterns of migrating soaring migrants indicate attraction to marine wind farms

Henrik Skov, Mark Desholm, Stefan Heinänen, Johnny A. Kahlert, Bjarke Laubek, Niels Einar Jensen, Ramūnas Žydelis & Bo Præstegaard Jensen
Monitoring of bird migration at marine wind farms has a short history, and unsurprisingly most studies have focused on the potential for collisions. Risk for population impacts may exist to soaring migrants such as raptors with K-strategic life-history characteristics. Soaring migrants display strong dependence on thermals and updrafts and an affinity to land areas and islands during their migration, a behaviour that creates corridors where raptors move across narrow straits and sounds and are attracted...

Data from: Assessing pre- and post-zygotic barriers between North Atlantic eels (Anguilla anguilla and A. rostrata)

Magnus W. Jacobsen, Line Smedegaard, Sune R. Sørensen, José M. Pujolar, Peter Munk, Bjarni Jónsson, Eyðfinn Magnussen & Michael M. Hansen
Elucidating barriers to gene flow is important for understanding the dynamics of speciation. Here we investigate pre- and post-zygotic mechanisms acting between the two hybridizing species of Atlantic eels: Anguilla anguilla and A. rostrata. Temporally varying hybridization was examined by analyzing 85 species-diagnostic single-nucleotide polymorphisms (SNPs; FST greater than or equal to0.95) in eel larvae sampled in the spawning region in the Sargasso Sea in 2007 (N=92) and 2014 (N=460). We further investigated whether genotypes...

Data from: Use of glacial fronts by narwhals (Monodon monoceros) in West Greenland

Kristin L. Laidre, Twila Moon, Donna D.W. Hauser, Richard McGovern, Mads Peter Heide-Joergensen, Rune Dietz, Benjamin Hudson, Donna D. W. Hauser & Ben Hudson
Glacial fronts are important summer habitat for narwhals (Monodon monoceros), however, no studies have quantified which glacial properties attract whales. We investigated the importance of glacial habitats using telemetry data from n=15 whales in September 1993-1994 and 2006-2007 in Melville Bay, West Greenland. For 41 marine-terminating glaciers, we estimated 1) narwhal presence/absence, 2) number of 24 h periods spent at glaciers, and 3) the fraction of narwhals that visited each glacier (at 5, 7, and...

Data from: On the accuracy of genomic selection

Charles-Elie Rabier, Philippe P. Barre, Torben T. Asp, Gilles G. Charmet & Brigitte B. Mangin
Genomic selection is focused on prediction of breeding values of selection candidates by means of high density of markers. It relies on the assumption that all quantitative trait loci (QTLs) tend to be in strong linkage disequilibrium (LD) with at least one marker. In this context, we present theoretical results regarding the accuracy of genomic selection, i.e., the correlation between predicted and true breeding values. Typically, for individuals (so-called test individuals), breeding values are predicted...

Data from: Historical colonization and dispersal limitation supplement climate and topography in shaping species richness of African lizards (Reptilia: Agaminae)

W. Daniel Kissling, Anne Blach-Overgaard, Roelof E. Zwaan & Philipp Wagner
To what extent deep-time dispersal limitation shapes present-day biodiversity at broad spatial scales remains elusive. Here, we compiled a continental dataset on the distributions of African lizard species in the reptile subfamily Agaminae (a relatively young, Neogene radiation of agamid lizards which ancestors colonized Africa from the Arabian peninsula) and tested to what extent historical colonization and dispersal limitation (i.e. accessibility from areas of geographic origin) can explain present-day species richness relative to current climate,...

Data from: Homogenous population genetic structure of the non-native raccoon dog (Nyctereutes procyonoides) in Europe as a result of rapid population expansion

Frank Drygala, Николай Кораблев, Hermann Ansorge, Joerns Fickel, Marja Isomursu, Morten Elmeros, Rafal Kowalczyk, Laima Baltrunaite, Linas Balciauskas, Urmas Saarma, Christoph Schulze, Peter Borkenhagen, Alain C. Frantz & Rafał Kowalczyk
The extent of gene flow during the range expansion of non-native species influences the amount of genetic diversity retained in expanding populations. Here, we analyse the population genetic structure of the raccoon dog (Nyctereutes procyonoides) in north-eastern and central Europe. This invasive species is of management concern because it is highly susceptible to fox rabies and an important secondary host of the virus. We hypothesized that the large number of introduced animals and the species’...
