Ongoing niche differentiation under high gene flow in a polymorphic brackish water threespine stickleback (Gasterosteus aculeatus) population
Østbye, Kjartan; Taugbøl, Annette; Ravinet, Mark; Harrod, Chris; Pettersen, Ruben Alexander; Bernatchez, Louis (Peer reviewed; Journal article, 2018)Background: Marine threespine sticklebacks colonized and adapted to brackish and freshwater environments since the last Pleistocene glacial. Throughout the Holarctic, three lateral plate morphs are observed; the low, partial ... -
Seasonal changes in European whitefish muscle and invertebrate prey fatty acid composition in a subarctic lake
Keva, Ossi; Tang, Patrik; Käkelä, Reijo; Hayden, Brian; Taipale, Sami J.; Harrod, Chris; Kahilainen, Kimmo Kalevi (Peer reviewed; Journal article, 2019)Ambient light and temperature show extreme seasonal variation in subarctic lakes due to the midnight sun period in summer and cold polar night period in winter. These changes have clear impacts on fish feeding and reproduction ... -
The temporal window of ecological adaptation in postglacial lakes: a comparison of head morphology, trophic position and habitat use in Norwegian threespine stickleback populations
Østbye, Kjartan; Harrod, Chris; Gregersen, Finn; Klepaker, Tom; Schulz, Michael; Schluter, Dolph; Vøllestad, Leif Asbjørn (Journal article; Peer reviewed, 2016)Background: Studying how trophic traits and niche use are related in natural populations is important in order to understand adaptation and specialization. Here, we des cribe trophic trait diversity in twenty-five ... -
