I am fascinated by and interested in almost all aspects of biology, especially evolutionary ecology and its connections to physiology. The main subject of interest for my research as a doctoral student is the interplay between the regulation of body temperature and metabolic rate in small birds and how these physiological processes are affected by other factors such as predation, risk of overheating, immunological responses and movement. My upcoming research will mainly concern two different physiological processes, overheating and rest-phase hypothermia, and the possible costs and benefits associated with those processes.
During winter I will conduct metabolic rate measurements together with continuous core body temperature measurements on roosting passerines from our nest-box colony in Revingehed in order to evaluate the relation between metabolic rate and core body temperature. Under this protocol I will also evaluate the effect of predatory stimuli on the use of rest-phase hypothermia.
During breeding season my main focus will be the risk of overheating in hard-working passerines. A significant elevated body temperature can potentially be lethal, but even a non-lethal increase in body temperature can have a detrimental effect on birds and I aim to study what costs a high body temperature might bring and if it actually might be the capacity to dissipate body heat that sets the limit for how hard a bird can work.
