Dietary l-tryptophan leaves a lasting impression on the brain and the stress response
Höglund, Erik; Øverli, Øyvind; Andersson, Madelene Åberg; Silva, Patricia; Laursen, Danielle Caroline; Moltesen, Maria M; Krogdahl, Åshild; Schjolden, Joachim; Winberg, Svante; Vindas, Marco Antonio; Mayer, Ian; Hillestad, Marie (Journal article; Peer reviewed, 2017)Comparative models suggest that effects of dietary tryptophan (Trp) on brain serotonin (5-hydroxytryptamine; 5-HT) neurochemistry and stress responsiveness are present throughout the vertebrate lineage. Moreover, hypothalamic ... -
Gamma irradiation during gametogenesis in young adult zebrafish causes persistent genotoxicity and adverse reproductive effects
Hurem, Selma; Gomes, Tania; Brede, Dag Anders; Mayer, Ian; Lobert, Viola; Mutoloki, Stephen; Gutzkow, Kristine Bjerve; Teien, Hans-Christian; Oughton, Deborah Helen; Alestrøm, Peter; Lyche, Jan Ludvig (Journal article; Peer reviewed, 2018)The biological effects of gamma radiation may exert damage beyond that of the individual through its deleterious effects on reproductive function. Impaired reproductive performance can result in reduced population size ... -
Neuroendocrine indicators of allostatic load reveal the impact of environmental acidification in fish
Höglund, Erik; Korzan, Wayne; Åtland, Åse; Haraldstad, Tormod; Høgberget, Rolf; Mayer, Ian; Øverli, Øyvind (Peer reviewed; Journal article, 2020)When mobilized from surrounding soils and binding to gills at moderately low pH, aluminum (Al) cations can adversely affect fish populations. Furthermore, acidification may lead to allostatic overload, a situation in which ... -
Sub-lethal UV radiation during early life stages alters the behaviour, heart rate and oxidative stress parameters in zebrafish (Danio rerio)
Hurem, Selma; Fraser, Thomas WK; Gomes, Tania; Mayer, Ian; Christensen, Terje (Journal article; Peer reviewed, 2018)Environmental UV radiation in sufficient doses, as a possible consequence of climate change, is potent enough to affect living organisms with different outcomes, depending on the exposure life stage. The aim of this project ...
