Project description Magnetosensing is mandatory for seasonal long distant flights of birds and butterflies from north to south and back and to find the home places of previous years. During the past 40 years strong evidence has been collected that for magnetic orientation blue light sensitive Cryptochromes within the retina of the eyes are responsible. However, since birds are able to navigate at very low light intensities during the night an interaction of the abundant rhodopsins with the only scarcely expressed Cryptochromes has been suggested. In the open project unusual rhodopsins of birds and butterflies and their interaction with Cryptochromes will be studied and characterized in detail in order to understand animal magnetic sensing. Behavioral studies will be carried out in collaboration with behavioral zoologists.
