Changes in the stress sensitivity of plants and ecosystems in a future climate. 01/10/2009 - 30/09/2011

Abstract

This project examines whether the resistance of plant communities and their composing species to stress will change in a future climate. Specifically, whether a future climate: 1) modifies the dose-response of stressors 2) modifies synergistic or anatagonistic effects between stressors 3) changes the influence of neighbours on the stress response of individuals.

Changes in the stress sensitivity of plants and ecosystems under climate change conditions. 01/10/2006 - 30/09/2007

Abstract

The central research question of this project is whether the resistance of species-rich plant communities to different stress factors will change in a future climate. To this end we will grow grassland mesocosms in sunlit controlled chambers under either the present or future climate conditions, and expose them to a wide range of stressors: drought, nitrogen deficiency, nitrogen saturation (eutrophication), and heavy metals (cadmium). Stressors will be applied separately to assess dose-response relations, but also in combination to examine their interactive impact. Besides evaluating the responses to stress in a future climate the experiments address basic questions, such as: are resistances to different stressors coupled ('co-tolerance')? or, can stress resistance be predicted from plant or community characteristics measured under normal climate conditions?
