    Temporal changes in microbially-mediated plant-soil feedback on Californian serpentine annuals

    Abstract: Microbially-mediated plant-soil feedback, where plants and soil microbes interact, is important in shaping plant performance and grassland communities. Plants are thought to 'condition' the soil by recruiting species-specific pathogens or mutualists that affect the next generation of plant coexistence. Classic experiments are conducted with grassland annual plant species but fail to incorporate the natural history of these plants. Specifically, the (1) seasonal time gap between senescence of one generation and growth of the next, and (2) litter decomposition and its effect on soils. In a greenhouse experiment using Acmispon wrangelianus, Festuca microstachys, and Plantago erecta, I show that legumes competitively excluded grasses and forbs, while grasses and forbs can coexist. However, the coexistence outcome changes when incorporating time and litter, showing the importance of temporal dimensions in plant-soil feedbacks. 

    Bio: Suzanne Ou is a PhD Candidate at Stanford University studying how soil microbes interact with plants and the consequences on plant community assembly and coexistence. Part of my work takes place in serpentine grasslands in Jasper Ridge Biological Preserve, Stanford University and Sedgwick Reserve, UC Santa Barbara, on the homelands of the Muwekma Ohlone Tribe and Chumash Tribe respectively.

    Compositional shifts in coastal plant communities and microclimates in response to tule elk herbivory

    Abstract: Species distributions are expected to shift across large spatial and temporal scales as species migrate to keep pace with anthropogenic climate change. Within a plant community, taxa from warmer regions or exposures (that are better adapted to the novel climate) will become more prevalent with increased warming and/or aridification. This process can be influenced or accelerated by disturbances or environmental processes that alter the availability of microclimates. Because grazing by native and introduced herbivores has complex effects on plant community composition and structure, grazing’s influence on microclimate availability may affect how an ecosystem responds to climate change. This study uses a 24-year exclusion experiment at the Tomales Point Tule Elk Preserve in Point Reyes National Seashore to investigate individual and interactive effects of grazing and microclimate on a coastal grassland plant community by combining fine-scale climatic data with plant community metrics across paired grazed and ungrazed plots. If grazed sites are warmer and drier, then grazed plant communities may already be adapting to future climate conditions and thereby may be more resilient to future climate change.
