Do genetic differences in growth thermal reaction norms maintain genetic variation in timing of diapause induction?
Fossen, Erlend Ignacio Fleck; Raeymaekers, Joost A. M.; Einum, Sigurd (Peer reviewed; Journal article, 2021)An optimal timing for diapause induction through the sexual production of dormant propagules is expected in organisms with temporary populations. Yet, empirical studies often find high within-population genetic variation ... -
An empirical test for a zone of canalization in thermal reaction norms
Fossen, Erlend Ignacio Fleck; Pelabon, Christophe; Einum, Sigurd (Journal article; Peer reviewed, 2018)Theoretical models on the evolution of phenotypic plasticity predict a zone of canalization where reaction norms cross, and genetic variation is minimized in the environment a population most frequently encounter. Empirical ... -
Genetic and environmental effects on the scaling of metabolic rate with body size
Fossen, Erlend Ignacio Fleck; Pelabon, Christophe; Einum, Sigurd (Peer reviewed; Journal article, 2019)Metabolic rate (MR) often scales with body mass (BM) following a power function of the form MR=aBMb, where log(a) is the allometric intercept and b is the allometric exponent (i.e. slope on a log–log scale). The variational ... -
Genetic Variation in Metabolic Rate and Correlations with Other Energy Budget Components and Life History in Daphnia magna
Einum, Sigurd; Fossen, Erlend Ignacio Fleck; Parry, Victor; Pelabon, Christophe (Peer reviewed; Journal article, 2019)Much is known about the genetic variance in certain components of metabolism, most notably resting and maximum metabolic rate. This is in stark contrast to the lack of information on genetic variance in the metabolic rate ... -
Inferring temperature adaptation from thermal performance curves of somatic growth rate: The importance of growth measurements and mortality
Einum, Sigurd; Bartuseviciute, Vitalija; Fossen, Erlend Ignacio Fleck; Pelabon, Christophe (Peer reviewed; Journal article, 2022)When comparing somatic growth thermal performance curves (TPCs), higher somatic growth across experimental temperatures is often observed for populations originating from colder environments. Such countergradient 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 ... -
Trait evolvability: effects of thermal plasticity and genetic correlations among traits
Fossen, Erlend Ignacio Fleck (Doctoral theses at NTNU;2018:377, Doctoral thesis, 2018)Summary of thesis: Trait evolvability: effects of thermal plasticity and genetic correlations among traits Climate change and increasing average temperatures are a big challenge for many populations of plants and ...
