Contrasting associations between breeding coloration and parasitism of male Arctic charr relate to parasite species and life cycle stage
Johansen, Ida Beitnes; Henriksen, Eirik Haugstvedt; Shaw, Jenny Carolyn; Mayer, Ian; Amundsen, Per-Arne; Øverli, Øyvind (Journal article; Peer reviewed, 2019)Conspicuous carotenoid ornamentation is considered a signal of individual “quality” and one of the most intensely studied traits found to co-vary with parasitism. Since it has been suggested that only “high quality” ... -

Depression-like state behavioural outputs may confer beneficial outcomes in risky environments
Vindas, Marco; Helland-Riise, Siri Helene; Nilsson, Göran Erik; Øverli, Øyvind (Peer reviewed; Journal article, 2019)Recent theories in evolutionary medicine have suggested that behavioural outputs associated with depression-like states (DLS) could be an adaptation to unpredictable and precarious situations. In animal models, DLS are ... -
