In view of globally-increasing species loss driven by environmental change, the importance of diversity for ecosystem processes and properties has recently aroused considerable attention in marine ecology.
We are aware that comprehending how marine ecosystem is likely to respond under climate change is important for planning future biodiversity conservation strategies. Over the last several years, numerous experiments have been performed to figure out how climate change alters species richness and primary productivity. However, our knowledge of function of marine plankton diversity across spatial and temporal scales and how it changes through the characteristics of the local ecosystems such as species interactions is still very limited compared to that of the diversity in the terrestrial world. Therefore, my PhD work aims at understanding the effects of climate change on marine plankton diversity using a three-dimensional ocean circulation model that is combined with biogeochemical cycles and marine plankton communities. My project is set up around two key questions: First, I will gain mechanistic insights into how the changes in species interactions, in particular consumer diversity, affect species distribution patterns and diversity-productivity/diversity-stability relationships across spatial scales. Second, I will investigate the direct/indirect effects of climate change on marine ecosystems via global warming scenario (changes in mean temperature and temperature variability). I will try to explain the interactions between consumption, competition and temperature based on functional traits of plankton, for example size, uptake strategy or thermal preference.
