Background and activities
I'm a PhD candidate in the Physiology Group at NTNU, where I am investigating survival strategies in bats. This involves disentangling various environmental effects on physiological and behavioural responses, mainly focusing on the use of torpor (short-term hibernation state).
As night-active mammals, the small bats in Norway face a huge challenge during summer: the midnight sun. By monitoring free-ranging brown long-eared bats (Plecotus auritus) and northern bats (Eptesicus nilsonii) at different latitudes (southern-, mid-, and northern-Norway), I aim to quantify the interrelation between torpor use and environmental variables. As part of my research I will develop an optimization model in order to determine which strategies that may optimize survival in bats of different states when faced with stochastic environments.
