← Nature & AnimalsWhich consequence results when seasonal temperature shifts disrupt geomagnetic alignment during salmon spawning migrations?
A)Increased disease susceptibility in hatchlings
B)Off-course navigation and reproductive failure✓
C)Elevated predation due to disrupted schooling
D)Accelerated decomposition of spawning habitats
💡 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.
