Effect of tree species, size, and accelerated succession on mycorrhizal colonization

Project Overview
Mycorrhizae are symbiotic fungi that form associations with roots to help absorb nutrients in return for carbohydrates. They provide a large part of the nutrients required, especially in low nutrient environments. Northern temperate forests such as those in northern Michigan are undergoing succession. Acer rubrum, Pinus strobus, and Quercus rubra are becoming the canopy dominant species as succession occurs in forests of the northern Great Lakes region. These three species are replacing early successional species such as Betula papyrifera and Populus spp. naturally. The Forest Accelerated Succession ExperimenT (FASET) was conducted at the University of Michigan Biological Station (UMBS) to accelerate the rate of this succession in order to study what effects the accelerated succession of the forest might have on the biosphere and atmosphere. The purpose of my research is to study the effects of this accelerated succesion and tree size on mycorrhizae colonization of Acer rubrum, Quercus rubra, and Pinus strobus.
