How mycorrhizal associations drive plant population and community biology

The pervasive power of mycorrhizas Associations between plants and symbiotic fungi—mycorrhizas—are ubiquitous in plant communities. Tedersoo et al. review recent developments in mycorrhizal research, revealing the complex and pervasive nature of this largely invisible interaction. Complex networks of mycorrhizal hyphae connect the root systems of individual plants, regulating nutrient flow and competitive interactions between and within plant species, controlling seedling establishment, and ultimately influencing all aspects of plant community ecology and coexistence.
