Adaptive host responses to infection can resemble parasitic manipulation
Jensen, Camilla Håkonsrud; Weidner, Jacqueline; Giske, Jarl; Jørgensen, Christian; Eliassen, Sigrunn; Mennerat, Adele (Journal article; Peer reviewed, 2023)Using a dynamic optimisation model for juvenile fish in stochastic food environments, we investigate optimal hormonal regulation, energy allocation and foraging behaviour of a growing host infected by a parasite that only ... -
Hormonal regulation of the phenotype into environmentally appropriate pace-of-life syndromes
Weidner, Jacqueline; Jensen, Camilla Håkonsrud; Giske, Jarl; Eliassen, Sigrunn; Jørgensen, Christian (Journal article; Peer reviewed, 2024)The risk of predation is an important driver that tailors life histories in various ways. Using an evolutionary model based on hormonal control, we study how different predation regimes affect adaptive risk-taking and ... -
Hormones as adaptive control systems in juvenile fish
Weidner, Jacqueline; Jensen, Camilla Håkonsrud; Giske, Jarl; Eliassen, Sigrunn; Jørgensen, Christian (Peer reviewed; Journal article, 2020-02-17)Growth is an important theme in biology. Physiologists often relate growth rates to hormonal control of essential processes. Ecologists often study growth as a function of gradients or combinations of environmental factors. ... -
Modelling fish growth under hormonal regulation as a factor in Pace of Life
Weidner, Jacqueline (Doctoral thesis, 2020-06-29)This thesis is written with the aim to increase the holistic understanding of growth in fish. As stated by Tinbergen (1963), to fully understand a behaviour or trait one needs to understand several perspectives of it. Those ...
