Effects of elevated CO2, nitrogen deposition, and decreased species diversity on foliar fungal plant disease
Abstract
Three components of global change, elevated CO 2, nitrogen addition, and decreased plant species richness (‘diversity’), increased the percent leaf area infected by fungi (pathogen load) for much to all of the plant community in one year of a factorial grassland experiment. Decreased plant diversity had the broadest effect, increasing pathogen load across the plant community. Decreased diversity increased pathogen load primarily by allowing remaining plant species to increase in abundance, facilitating spread of foliar fungal pathogens specific to each plant species. Changes in plant species composition also strongly influenced community pathogen load, with communities that lost less disease prone plant species increasing more in pathogen load. Elevated CO 2 increased pathogen load of C 3 grasses, perhaps by decreasing water stress, increasing leaf longevity, and increasing photosynthetic rate, all of which can promote foliar fungal disease. Decreased plant diversity further magnified the increase in C 3 grass pathogen load under elevated CO 2. Nitrogen addition increased pathogen load of C 4 grasses by increasing foliar nitrogen concentration, which can enhance pathogen infection, growth, and reproduction. Because changes in foliar fungal pathogen load can strongly influence grassland ecosystem processes, our study suggests that increased pathogen load can be an important mechanism by which global change affects grassland ecosystems.

“Nitrogen addition can cause grasslands to shift from C 4 Ðdominated to C 3 Ðdominated (Tilman, 1987); our results suggest that increased foliar fungal disease could contribute to this shift.”

“In monocultures of our experiment, foliar nitrogen concentration in C 4 grasses was lower than in all other functional groups at ambient nitrogen supply, and increased the most both proportionally and absolutely in response to nitrogen addition (Reich et al., 2001b).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
