Understanding microbial landscapes : biogeography of plant-fungal interactions in the face of warming and wildfire
Abstract/Contents
- Abstract
- Understanding the distribution and abundances of species across the globe has long been a focus of the ecological field. While these patterns have been easily observed for plants, animals, and macrofungi, recently developed molecular tools have revolutionized our ability to characterize the biogeographies of microorganisms. In this dissertation, I use field surveys, greenhouse experiments, and modeling to explore spatial patterns of plant-fungal interactions, attempting to understand the unseen microbial landscape and its response to global change stressors like warming and wildfire. In the first chapter, I illustrate how microbial traits like uni- vs multicellularity affect regional patterns of fungal and bacterial biogeography across many biome types in Minnesota. In the second chapter, I explore changes in the composition of the mycobiome hosted by trees in the genus Populus across a continental range of environments and how these distributions might change in future climate regimes. In the third and fourth chapters, I show how wildfire changes the composition of soil microbial communities in coast redwood forests, and how these shifts in microbial composition affect seedling growth and competitive ability with potential for impacts on long term forest composition. Taken together, these chapters use multiple approaches to investigate the spatial heterogeneity of plant-microbe interactions and what this could mean for forest composition and function.
