Spatiotemporal dynamics of plant-soil-microbe interactions
Abstract/Contents
- Abstract
- Understanding how communities assemble across space and time remains a fundamental ecological question. In this dissertation, I investigate how plants, soil, and microbes interact to shape the outcome of aboveground and belowground communities. To understand temporal dimensions of microbially mediated plant-soil feedback, I quantified how the strength of conspecific and heterospecific feedback changes over time in greenhouse experiments. Using molecular sequencing, I show that plant-associated microbial communities changes within a plant generation, depending on the initial microbial source. I then show that microbial community turnover between generations affects the coexistence outcomes of plant communities driven by natural gaps in growing seasons and litter decomposition. In the spatial dimension, I use spatially-explicit field data to show how plant and microbial community distribution varies in relation to soil nutrients. Using observations from forest dynamics plots, I show that mycorrhizal association drives the aggregation patterns of trees across a gradient of soil fertility, interacting with the dispersal mode of different species and age structure within each species. All together, my dissertation explores various temporal and spatial structures of plant--soil--microbe interactions and their role in shaping species diversity above- and belowground.
