Evolution of haemocyanin and its influence on thermal sensitivity in cold adapted cephalopods

Description: Das Projekt "Evolution of haemocyanin and its influence on thermal sensitivity in cold adapted cephalopods" wird vom Umweltbundesamt gefördert und von Stiftung Alfred-Wegener-Institut für Polar- und Meeresforschung e.V. in der Helmholtz-Gemeinschaft (AWI) durchgeführt. Temperature, pH and oxygen concentration are the three most important parameters that influence oxygen-binding capacities of cephalopod blood and for survival at nearly -2 degree Celsius, a cephalopod requires a highly specialised blood-gas exchange. By using extracellular haemocyanin, cephalopods possess a less effective respiratory protein than fish (which have intracellular haemoglobin). In order to successfully compete with fish, cephalopods have developed a high level of haemocyanin adaptability. Despite their prominent position in Antarctic food webs and being highly abundant, very little is known about Antarctic octopod physiology in general and specifically of the role of haemocyanin as a mediator between the organism and an extreme environment. By means of an integrative physiological and molecular genetic approach, this study aims to shed light on the physiological adaptation as well as the phylogeny of octopodid haemocyanin during the adaptive radiation of these animals into Antarctic waters and to assist in explaining the recent biogeography of Antarctic octopods.
