La Niña’s effect on wildlife

by simon

The cool phase of an ocean cycle (opposite to El Niño) that periodically sees a reduction in warm water flow across the Pacific. La Niña‘s effect on wildlife is that it usually means more nutrients reaching the west Pacific and a strengthening of normal wind patterns leading to more rainfall in Australasia. For marine animals, it pushes the mixed layer closer to the surface, making it easier for them to feed. However, food is also more spread out, so they have to expend more energy finding food.

La Niña's effect on wildlife
La Niña’s effect on wildlife: Cooler surface water means the nutrient-filled mixed layer is shallow. With a lot of food about, animals spread out across the ocean but it means density of prey is lower, which means a bumper time for prey but harder for predators to make a living.
