Abstract

Nowadays, the impact of drought on plant communities is a significant concern in the face of global climate change. In this paper, we developed a dynamic vegetation model to investigate the impact of drought on a community of lichen, a symbiotic association of fungi and algae. Our model considers the impact of drought on population size and inter-specific relationships in the community, and predicts how the community will change over time during drought and rainy seasons. We found that the community's response to drought is highly dependent on the number of species present, and the types of species in the community can have a significant impact on the overall population. Our results suggest that a greater frequency and wider variation of the occurrence of droughts in future weather cycles could have significant implications for the stability of lichen communities.
