Tracing a Mycorrhizal Symbiosis from Colonization Through Ecosystem Effect
Captions available
The idea
This capstone traces one arbuscular mycorrhizal symbiosis from a Glomeromycota spore's germination and root colonization through nutrient exchange to its effect on the surrounding plant community.
Where people slip
The mutualism traced here depends on both the endomycorrhizal structure formed at colonization and the sustained two-way exchange that follows— an association that stalls at colonization without establishing exchange in both directions confers no benefit to either partner.
