Life in a cold-water environment: allometric adaptations of cetaceans in Skjálfandi Bay, Iceland.
December 5th, 12:00 to 13:00 Askja N-129, Maria Glarou will present her phd work.
The aim of the PhD project is to examine how certain ecophysiological and bioenergetic characteristics, such as heat loss rates, field metabolic rates and energetic requirements, vary allometrically across five sympatric cetacean species, regularly found in Icelandic waters.
Why do endotherms spend so much energy? In this study, Juan G. Rubalcaba describes a theoretical model that shows that species followed one of two possible evolutionary patches: live fast while spending a lot (homeotherms), live slowly and keep your costs low (heterotherms).

Many #endotherms 🦇🐦 respond to challenging environmental conditions (e.g., extreme temperatures 🌡️, low food availability) by entering #dormancy. That is, they greatly decrease their #MetabolicRate and body temperature and, by doing so, reduce their energy expenditure. 1/4
