TY - T1 - Annual variation in predation risk is related to the direction of selection for brain size in the wild SN - / UR - http://hdl.handle.net/10138/321474 T3 - A1 - Jaatinen, Kim; Moller, Anders P.; Ost, Markus A2 - PB - Y1 - 2019 LA - eng AB - The direction of predator-mediated selection on brain size is debated. However, the speed and the accuracy of performing a task cannot be simultaneously maximized. Large-brained individuals may be predisposed to accurate but slow decision-making, beneficial under high predation risk, but costly under low risk. This creates the possibility of temporally fluctuating selection on brain size depending on overall predation risk. We test this idea in nesting wild eider females (Somateria mollissima), ...
