| Beschreibung: |
Climate change is having a massive impact on plant communities, altering species composition and ecosystem services. In particular, increasing drought has been identified as a major threat to plant biodiversity, which may be exacerbated in combination with other environmental changes such as eutrophication or land-use change. While recent empirical studies have focused on the effect of drought intensity on plant communities, much less attention has been paid to its timing. Drought events can occur at different times within years, but can also vary between years. How plant species respond to such variation is likely to depend on their functional traits, which include phenology and traits related to water acquisition and photosynthetic capacity. In addition, the timing of drought events is expected to alter the dynamics of species interactions, such as competition, which will ultimately alter coexistence mechanisms and thus biodiversity.The DFG-funded GrassYear project offers a PhD position using computer simulations to investigate the effects of inter-annual precipitation variability on grassland communities.
Job requirements
•Experience in computer simulation modelling (preferably individual-based or agent-based)
•Excellent Master's degree in a related scientific field (ecology, biology or other natural sciences; applied mathematics will also be considered)
•Strong interest in understanding ecological dynamics under the influence of climate change
•Excellent written and verbal communication skills in English
|
| Methoden: |
The candidate will apply and refine an individual-based model of grassland communities to explore the short- and long-term effects of different specific timing, intensity and autocorrelations of drought stress, and the role of intra- and interspecific interactions in understanding and predicting community responses to different climate change scenarios.
