Serpentine soils do not limit mycorrhizal fungal diversity.
<h4>Background</h4>Physiologically stressful environments tend to host depauperate and specialized biological communities. Serpentine soils exemplify this phenomenon by imposing well-known constraints on plants; however, their effect on other organisms is still poorly understood.<h4&g...
