A new paper by Zophonías O. Jónsson, Han Xiao, Sigurður S. Snorrason and Arnar Pálsson, along with many international collaborators presents the first genome Arctic charr and interesting population genetic analyses of charr in two

The availability of resources varies across a species distributional range, and a low-productivity area can make a species more vulnerable. We investigated the invertebrate composition and prey choice of juvenile Atlantic salmon (Salmo salar L.)

Salmonids are especially vulnerable during their embryonic development, but monitoring of their spawning grounds is rare and often relies on manual counting of their nests (redds). This method, however, is prone to sampling errors resulting

How fast can evolution shape morphologies and anatomical forms in animals? Iceland was covered by ice-age cap about 20.000 years ago, and after the glaciation waterways opened up and were colonized by multiple species. Among
