Title:Emerging fungal pathogen differentially affects three native plant species that compete with an invasive grass
Alternate Identifier:DOI PLACE HOLDER
Abstract:

This data package includes data and code from an experiment testing the effects of a leaf spot fungal infection and competition from the invasive (to the U.S.) grass Microstegium vimineum on the performance of three native grass species: Dichanthelium clandestinum, Elymus virginicus, and Eragrostis spectabilis. The experiment was performed between June and September of 2019 in a greenhouse on the University of Florida campus in Gainesville, FL, USA. The leaf spot infection is caused by the fungal pathogen Bipolaris gigantea, which has recently emerged on populations of M. vimineum in the U.S. We tested the hypothesis that infection of B. gigantea would both directly and indirectly affect the native grass species by measuring the change in biomass of each species with and without pathogen inoculation (direct effects) and by measuring the effect of pathogen inoculation on M. vimineum competition through changes in native grass biomass across a density gradient of M. vimneum (indirect effects). The code includes statistical analyses and figures. The code was run using R (version 4.0.1).

Methods and protocols used in the collection of this data package
Description:

Motivation: Plant communities can experience species invasions and infectious disease at the same time, but it is unclear what the consequences are, partly because most investigations feature only one native species. We examined the effects of disease and invasion on three native species. The invasive species is Microstegium vimineum, a forest understory grass, which hosts fungi in the genus Bipolaris that are spreading across the invaded range.

Design: In a greenhouse experiment, we manipulated, pathogen inoculation, native species identity, and M. vimineum density to measure the effects of disease, competition from an invasive plant, and both on the biomass production of the native species. We used two inoculation treatments (pathogen inoculation with a spore solution of Bipolaris gigantea and a mock inoculation control), three native species (Elymus virginicus, Eragrostis spectabilis, and Dichanthelium clandestinum), and five levels of M. vimineum density (0, 2, 10, 50, 100 seeds per pot). Crossing these three treatments in a full-factorial design led to 30 treatments with four replicate pots each.

Measurements: We quantified disease incidence by counting the number of M. vimineum leaves per pot with lesions and then counting the total number of leaves on three seedlings (or two when only two were available). For the native plants, we counted the number of leaves with lesions and the total number of leaves per plant when plants had lesions. At the end of the experiment, we harvested aboveground biomass, oven-dried it to a constant weight, and weighed it.

Analysis: We used the brms package to fit Bayesian models to each response variable. We fit a binomial linear regression to disease incidence data for M. vimineum with native species identity, M. vimineum density, and their interaction as the explanatory variables. We could not fit a model to the disease incidence data for the native species because there were too few data points. We fit a linear regression to M. vimineum biomass with pathogen inoculation treatment, native species identity, M. vimineum density (represented with a linear and quadratic term), and their interactions as the explanatory variables. We fit a Beverton-Holt function to native plant biomass across the range of M. vimineum density values with different parameters for each native species-pathogen inoculation treatment combination.
