Abstract

Seasonal rainfall is predicted to decrease by 50 percent by 2038 due to anthropogenic climate change. Little is known about the effect this will have on below-ground responses in arbuscular mycorrhizal fungi (AMF). Two hypotheses exist for the effect reduced rainfall may have on root colonization by AMF: (1) increase in hyphae and fungal elements due to increased carbon allocation by the host plant, (2) decrease in hyphae and fungal elements due to sensitivity of plants to shift in seasonal drought. This study examines the effect of seasonal shifts in rainfall on root colonization in a lowland tropical forest in the Yucatan Peninsula, Mexico.
