Data from: Infanticide as a male reproductive strategy has a nutritive risk effect in brown bears

Behavioral strategies to reduce predation can incur costs (i.e. risk effects). A common strategy to avoid predation is spatiotemporal avoidance of predators, in which prey typically trade optimal resources for safety. Analogous with predator-prey theory, risk effects should also arise in species with sexually selected infanticide (SSI), in which females with dependent offspring avoid infanticidal males. In brown bears (Ursus arctos), SSI is common and explains spatiotemporal segregation among reproductive classes. Here, we show that...

Data from: Fungi ahoy! Diversity on marine wooden substrata in the high North

Teppo Rämä, Jenni Nordén, Marie L. Davey, Geir H. Mathiassen, Joseph W. Spatafora & Håvard Kauserud
Marine fungi are severely understudied in the polar regions. We used molecularly identified cultures to study fungi inhabiting 50 intertidal and sea-floor logs along the North Norwegian coast. The aim was to explore the taxonomic and ecological diversity and to examine factors shaping the marine wood-inhabiting fungal communities. The 577 pure cultures analyzed clustered into 147 operational taxonomic units (OTUs) based on 97 % ITS sequence similarity. Ascomycota dominated, but OTUs belonging to Basidiomycota, Mucoromycotina...

Data from: Large fluctuations in the effective population size of the malaria mosquito Anopheles gambiae s.s. during vector control cycle

Theresa K. Hodges, Giridhar Athrey, Kevin C. Deitz, Hans J. Overgaard, Abrahan Matias, Aldalgisa Caccone, Michel A. Slotman & Adalgisa Caccone
On Bioko Island, Equatorial Guinea, indoor residual spraying (IRS) has been part of the Bioko Island Malaria Control Project since early 2004. Despite success in reducing childhood infections, areas of high transmission remained on the island. We therefore examined fluctuations in the effective population size (N_e) of the malaria vector Anopheles gambiae in an area of persistent high transmission over two spray rounds. We analyzed data for 13 microsatellite loci from 791 An. gambiae specimens...

Data from: Landscape genomics in Atlantic salmon (Salmo salar): searching for gene-environment interactions driving local adaptation

Vincent Bourret, Mélanie Dionne, Matthew Peter Kent, Sigbjørn Lien, Louis Bernatchez & Bourret Vincent
A growing number of studies are examining the factors driving historical and contemporary evolution in wild populations. By combining surveys of genomic variation with a comprehensive assessment of environmental parameters, such studies can increase our understanding of the genomic and geographical extent of local adaptation in wild populations. We utilized a large-scale landscape genomics approach to examine adaptive and neutral differentiation across 54 North American populations of Atlantic salmon representing seven previously defined genetically distinct...
