Which consequence results when seasonal temperature shifts disrupt geomagnetic alignment during salmon spawning migrations?

💡 Explanation

Off-course navigation occurs because geomagnetic alignment guides migration; temperature-driven shifts interfere with the magnetic compass mechanism, leading to disorientation affecting spawning success. Therefore reproductive failure results, rather than disease or predation which involves different mechanisms.
