Without replenishment, land suffers from nutrient depletion and becomes either unusable or suffers from reduced yields.

Exposing soil to erosion leads to further nutrient depletion.

Removal of the natural vegetation, overgrazing and overcropping have resulted in nutrient depletion, widespread soil erosion and desertification (section 7.2.1 for a definition).

Stress due to warm water and nutrient depletion can increase the susceptibility of kelp to storm damage and herbivorous grazing, sometimes even prompting phase shifts to urchin-dominated landscapes.

Additionally, experiments are suggesting Whi2 for playing a role in Ras2 deactivation or degradation during nutrient depletion.

They could no more anticipate the problem of salinization than of nutrient depletion resulting from agriculture.

Similar to the situation in yeast, the activation process of LC3 is triggered by nutrient depletion, but interestingly also in response to hormones.

There is also the vexing question of nutrient depletion.

The second is that the fetus itself may promote local immunosuppression in the mother, perhaps by a process of active nutrient depletion.

This was due to deeper plow cuts in the soil that allowed the soil more contact with oxygen causing nutrient depletion.
