Are model organisms representative for climate change research? Testing thermal tolerance in wild and laboratory zebrafish populations
Morgan, Rachael; Sundin, Josefin; Finnøen, Mette Helene; Dresler, Gunnar; Vendrell, Marc Martinez; Dey, Arpita; Sarkar, Kripan; Jutfelt, Fredrik (Journal article; Peer reviewed, 2019)Model organisms can be useful for studying climate change impacts, but it is unclear whether domestication to laboratory conditions has altered their thermal tolerance and therefore how representative of wild populations ... -
Behavioural traits correlate in zebrafish (Danio rerio) selected for high and low upper thermal tolerance
Brusevold, Tine Elisabeth Dahl (Master thesis, 2019)Ferskvannssystemer er spesielt sårbare for klimaforandringer, så forskning på ferskvannsorganismer i lys av temperaturforandringer er viktig. I denne studien, ble sebrafisk selektert gjennom fire generasjoner for øvre ... -
CTmax is repeatable and doesn't reduce growth in zebrafish
Morgan, Rachael; Finnøen, Mette Helene; Jutfelt, Fredrik (Journal article; Peer reviewed, 2018)Critical thermal maximum (CTmax) is a commonly and increasingly used measure of an animal’s upper thermal tolerance limit. However, it is unknown how consistent CTmax is within an individual, and how physiologically taxing ... -
Personality and pace-of-life behavioral syndromes in a model species, the House Sparrow (Passer domesticus)
Finnøen, Mette Helene (Master thesis, 2016)Consistent individual differences in behaviour ( animal personality ) may be favoured by natural selection because they are driven by adaptive differences in life-history and physiology traits, constituting a pace-of-life ... -
Reduced physiological plasticity in a fish adapted to stable temperatures
Morgan, Rachael Louise; Andreassen, Anna H.; Åsheim, Eirik Ryvoll; Finnøen, Mette Helene; Dresler, Gunnar; Brembu, Tore; Loh, Adrian; Miest, Joanna J.; Jutfelt, Fredrik (Peer reviewed; Journal article, 2022)Plasticity can allow organisms to maintain consistent performance across a wide range of environmental conditions. However, it remains largely unknown how costly plasticity is and whether a trade-off exists between plasticity ... -
Selection on high thermal tolerance alters tolerance to cold
Hildrum, Hanne Margrethe (Master thesis, 2019)Klimaendringer vil føre til økning i vanntemperaturer og intensitet av hetebølger. Dette vil utfordre ektoderme fiskers indre fysiologi og populasjonsutbredelse, delvis avhengig av deres temperatur-toleranse. Et vanlig mål ...
