Abstract

Over the last decades human activities have strongly affected ecosystems with pervasive increases in nutrient loadings abiotic stress and altered herbivore pressure The evaluation of how those environmental factors interact to influence plant–pathogen interactions under natural conditions becomes essential to fully understand the ecology of diseases and anticipate the possible effects of global change on natural and agricultural systems In a SW Atlantic salt marsh we performed a field factorial experiment to evaluate the effect of herbivory salinity and nutrient availability three main limiting factors for salt marsh plant growth on the infection of the fungus Claviceps purpurea ergot upon the cordgrass Spartina densiflora Results show that herbivory has no effect but both nutrients and salinity increase fungal infection The combined effect of salinity and nutrients is not additive but interactive Salinity stress increases infection at ambient nutrient levels but in combination with fertilizer it buffers the higher infection produced by increased nutrient availability Since both nitrogen availability and salinity are factors predicted to globally increase due to human impact on ecosystems this interaction between environmental factors and ergot infection can have strong effects on natural and productive agricultural systems
