Factors influencing return rate and marine residence durationin sea trout populations in Central Norway
Paterson, Rachel; Berntsen, Johan Henrik Hårdensson; Næsje, Tor; Berg, Marius; Finstad, Bengt (Peer reviewed; Journal article, 2021)Brown trout (Salmo trutta) display extensive plasticity in marine migratory behaviours, with marine migrations considered to be an adaptive strategy which enables sea trout to maximize growth and reproductive potential. ... -
Incubation temperature and physiological aging in the zebra finch
Berntsen, Johan Henrik Hårdensson; Bech, Claus (Peer reviewed; Journal article, 2021)In birds, incubation temperature has received increased attention as an important source of phenotypic variability in offspring. A lower than optimal incubation temperature may negatively affect aspects of nestling physiology, ... -
Individual variation in survival: The effect of incubation temperature on the rate of physiological ageing in a small passerine bird
Berntsen, Johan Henrik Hårdensson (Doctoral thesis at NTNU;2016:79, Doctoral thesis, 2016) -
Is the rate of metabolic ageing and survival determined by basal metabolic rate in the zebra finch?
Rønning, Bernt; Moe, Børge; Berntsen, Johan Henrik Hårdensson; Noreen, Elin; Bech, Claus (Journal article; Peer reviewed, 2014-09-29)The relationship between energy metabolism and ageing is of great interest because aerobic metabolism is the primary source of reactive oxygen species which is believed to be of major importance in the ageing process. We ...
