Is there plasticity in developmental instability? The effect of daily thermal fluctuations in an ectotherm
Kielland, Øystein Nordeide; Bech, Claus; Einum, Sigurd (Journal article; Peer reviewed, 2017)Diversified bet‐hedging (DBH) by production of within‐genotype phenotypic variance may evolve to maximize fitness in stochastic environments. Bet‐hedging is generally associated with parental effects, but phenotypic variation ... -
Negative relationships between population density and metabolic rates are not general
Yashchenko, Varvara; Fossen, Erlend Ignacio Fleck; Kielland, Øystein Nordeide; Einum, Sigurd (Journal article; Peer reviewed, 2016)Population density has recently been suggested to be an important factor influencing metabolic rates and to represent an important ‘third axis’ explaining variation beyond that explained by body mass and temperature. In ... -
No evidence for thermal transgenerational plasticity in metabolism when minimizing the potential for confounding effects
Kielland, Øystein Nordeide; Bech, Claus; Einum, Sigurd (Journal article; Peer reviewed, 2017)Environmental change may cause phenotypic changes that are inherited across generations through transgenerational plasticity (TGP). If TGP is adaptive, offspring fitness increases with an increasing match between parent ... -
Quantitative mismatch between empirical temperature-size rule slopes and predictions based on oxygen limitation
Einum, Sigurd; Bech, Claus; Kielland, Øystein Nordeide (Peer reviewed; Journal article, 2021)In ectotherms, adult body size commonly declines with increasing environmental temperature, a pattern known as the temperature-size rule. One influential hypothesis explaining this observation is that the challenge of ... -
Size-dependent habitat use of juvenile brown trout (Salmo trutta L.) in an artificial river
Kielland, Øystein Nordeide (Master thesis, 2013)Effektkjøring i vannkraftverk gir økt variasjon i vannstand med mulige skadelige effekter på organismer som lever i elver. Fisker, som forekommer i de grunne habitatene av elva, kan være sårbare for stranding og dermed ha ... -
Sources of variation in metabolism of an aquatic ectotherm
Kielland, Øystein Nordeide (Doctoral theses at NTNU;2017:370, Doctoral thesis, 2017)Summary of thesis: An important aspect of ecology is being able to predict and explain how life can adapt to environmental changes. Paramount in making accurate predictions is the disentangling of trait variation, and ...
