Automated measurement of upper thermal limits in small aquatic animals
Burton, Tim; Zeis, Bettina; Einum, Sigurd (Journal article; Peer reviewed, 2018)We present a method for automating the measurement of upper thermal limits in small aquatic organisms. Upper thermal limits are frequently defined by the cessation of movement at high temperature, with measurement being ... -
Divergence in rates of phenotypic plasticity among ectotherms
Einum, Sigurd; Burton, Tim (Peer reviewed; Journal article, 2022)An individual's fitness cost associated with environmental change likely depends on the rate of adaptive phenotypic plasticity, and yet our understanding of plasticity rates in an ecological and evolutionary context remains ... -
Does the rate of plasticity in active regulation of hemolymph osmolality and salinity tolerance depend on temperature?
Christoffersen, Kaja Maczko (Master thesis, 2024)Både omfanget og hastigheten av global oppvarming har fått økt oppmerksomhet de siste årene, og det har blitt enda viktigere å undersøke og forstå hvordan ulike organismer responderer på variasjoner i miljøet. Flere studier ... -
Environmental change and the rate of phenotypic plasticity
Burton, Tim; Ratikainen, Irja Ida; Einum, Sigurd (Peer reviewed; Journal article, 2022)With rapid and less predictable environmental change emerging as the ‘new norm’, understanding how individuals tolerate environmental stress via plastic, often reversible changes to the phenotype (i.e., reversible phenotypic ... -
Evolution of population dynamics following invasion by a non-native predator
Einum, Sigurd; Ullern, Emil R.; Walsh, Matthew; Burton, Tim (Peer reviewed; Journal article, 2022)Invasive predatory species are frequently observed to cause evolutionary responses in prey phenotypes, which in turn may lead to evolutionary shifts in the population dynamics of prey. Research has provided a link between ... -
Evolutionary change in metabolic rate of Daphnia pulicaria following invasion by the predator Bythotrephes longimanus
Rani, Varsha; Burton, Tim; Walsh, Matthew; Einum, Sigurd (Peer reviewed; Journal article, 2022)Metabolic rate is a trait that may evolve in response to the direct and indirect effects of predator-induced mortality. Predators may indirectly alter selection by lowering prey densities and increasing resource availability ... -
Evolutionary change in metabolism of Daphnia pulicaria in response to the invasive predator Bythotrephes longimanus
Rani, Varsha (Master thesis, 2021)Invasive predators have been identified as one of several threats to global biodiversity. This makes it necessary to understand their potential lethal and non-lethal impacts on native species, communities, and ecosystems. ... -
How to quantify thermal acclimation capacity?
Einum, Sigurd; Ratikainen, Irja Ida; Wright, Jonathan; Pelabon, Christophe; Bech, Claus; Jutfelt, Fredrik; Stawski, Clare; Burton, Tim (Peer reviewed; Journal article, 2019)The capacity of organisms to acclimate will influence their ability to cope with ongoing global changes in thermal regimes. Here we highlight methodological issues associated with recent attempts to quantify variation in ... -
Is the rate and capacity of phenotypic plasticity limited by energy availability?
Graham, Martine (Master thesis, 2024)Med klimaendringer som overgår tidsrammen til evolusjonære mekanismer, kan evnen til å tilpasse seg gjennom fenotypisk plastisitet være viktigere enn noen gang. Disse fenotypiske endringene innenfor en organismes livstid, ... -
Modelling thermal preference and fitness consequences in scenarios of decreasing temperature predictability
Olsen, Tora (Master thesis, 2019)Klimaendringane er venta å auke snittemperaturen, men også variasjon og føreseielegheit i temperatur. Nøyaktige predikasjonar av framtidig førekomst og foredling av artar må difor ta omsyn også til desse faktorane. Fordi ... -
The old and the large may suffer disproportionately during episodes of high temperature: evidence from a keystone zooplankton species
Burton, Tim; Einum, Sigurd (Peer reviewed; Journal article, 2020)Widespread declines in the body size of aquatic ectotherms have been attributed to the poorer ability of older, larger individuals to tolerate high temperature. Here, using the thermal death time curve framework, we ...
