elevated [co2] and increased n supply reduce leaf disease and related photosynthetic impacts on solidago rigida.	to evaluate whether leaf spot disease and related effects on photosynthesis are influenced by increased nitrogen (n) input and elevated atmospheric co(2) concentration ([co(2)]), we examined disease incidence and photosynthetic rate of solidago rigida grown in monoculture under ambient or elevated (560 micromol mol(-1)) [co(2)] and ambient or elevated (+4 g n m(-2) year(-1)) n conditions in a field experiment in minnesota, usa. disease incidence was lower in plots with either elevated [co(2)] or ...	2006	16736182
stoichiometric response of nitrogen-fixing and non-fixing dicots to manipulations of co2, nitrogen, and diversity.	human activities have resulted in increased nitrogen deposition and atmospheric co(2) concentrations in the biosphere, potentially causing significant changes in many ecological processes. in addition to these ongoing perturbations of the abiotic environment, human-induced losses of biodiversity are also of major concern and may interact in important ways with biogeochemical perturbations to affect ecosystem structure and function. we have evaluated the effects of these perturbations on plant bi ...	2007	17106721
