Temperate forests have a large impact on greenhouse gas cycling, making up 16% of land area on Earth and 34% of global carbon sinks. As climate change increases the frequency and intensity of extreme weather events, natural disasters such as hurricanes may become more commonplace in temperate forests, disrupting ecosystems and changing landscapes. Hurricane disturbances create new microtopography on the forest floor consisting of pits and mounds formed by the upturned root system. These variations in microtopography may have large effects on the soil ecosystem and its nutrient cycling processes. My project looks specifically at mycorrhizal fungi populations, which influence nutrient cycling by: promoting tree growth which stores carbon in woody biomass, breaking down decaying plant litter to be stored in the soil long-term as soil organic matter, and transforming nutrients into microbially accessible forms. To explore this dynamic between fungal hyphae and hurricane associated microtopography, soil sampling was conducted at the Harvard Forest at the Hurricane Manipulation Experiment plot where in 1990, ~65% of standing tree biomass was felled. Mycelium was extracted from soil samples inside of pit formations as well as a flat transect, and hyphal length was measured as a proxy for fungal biomass in both organic and mineral soil horizons. I hypothesize that greater hyphal length occurs in pits compared to flat transect due to pits providing a favorable habitat for mycorrhizal hyphae, with higher soil moisture and greater accumulation of plant material available for decomposition. Preliminary findings suggest that hurricane disturbances and related microtopography are not likely to drive differences in mycorrhizal biomass. Future studies may look into differences in fungal species or traits and how they impact carbon storage in pits versus flat flat transects.
