Phenology of Arbuscular Mycorrhizal fungi and Dark Septate Endophytes across an elevation gradient.
Abstract
Arbuscular Mycorrhizal Fungi (AMF) and Dark Septate Endophytes (DSE) participate in symbiotic relationships with host plants in the Rocky Mountains. The effects of plant-host phenology on these fungal symbionts is important in our understanding of how climate changes effects on plants will change the dynamics of this symbiotic relationship. In this observational study, I took plant-root core samples at three locations from three different plant species on three different dates throughout the growing season and recorded the AMF and DSE colonization. The data revealed that AMF colonization decreases consistently, in all elevations except the high elevation where it rapidly decreases, throughout the season, while DSE increases consistently in all sites. These results are important because they give us insight into what environmental effects dictate symbiotic fungal growth and how climate change could have implications on future seasons.
