Carpinteria Salt Marsh Reserve

15 Jul, 07 AM - 15 Jul, 08 AM

Global change is pervasive in Southern California. Rates of anthropogenic N deposition can exceed 35 kg ha-1 y-1 in this region (Fenn et al., 2003), while annual precipitation in the area is predicted to decrease by 5 to 10% this century (Christensen et al., 2007). Each of these changes is known to lead to disruptions in soil dynamics via changes in fungal communities. However, if the fungal community is able to shift in response to the environmental change, functions may recover to some extent. Migration of fungi from other habitats is one mechanism that would lead to community shifts. I will examine the ability of fungi to travel and proliferate within the UC reserves and National parks and forests in Southern California. These experiments will allow us to understand the current biogeography of soil fungi in Southern California and how these microbial communities assemble via airborne dispersal. I will sample soils within 16 ecosystems distributed across Southern California (Fig. 1). These ecosystems represent a range in ecosystem types, elevation, soil types and water availability. I will collect ten, 10cm deep soil cores every three months over the first year of the study. A portion of each sample will be used to measure soil pH, organic C, and resin-extractable N and P, and the remainder will be stored for community composition analysis. I will characterize the community composition of each sample by using pyrosequencing. I will analyze community composition in all sites using NMS combined with MRPP and Mantel tests.
