Multi-BEF : Impacts of the surrounding multitrophic biodiversity on ecosystem multifunctionality
Encadrement : Gaëtane Le-Provost (INRAE, UMR SAVE)
Financement : The German Research Foundation (DFG)
Période : 2023 - 2026

Description du projet

Biodiversity-Ecosystem Functioning (BEF) research has established that plot-scale biodiversity can significantly influence various ecosystem functions. However, the implications of large-scale biodiversity changes on ecosystem services remain relatively unexplored. Recent empirical studies have highlighted the critical role of surrounding plant diversity in supporting ecosystem services (e.g., Le Provost et al. 2023). However, most studies have primarily focused on plant diversity alone, while previous research has emphasized the importance of biodiversity across multiple trophic levels in sustaining ecosystem functioning (Soliveres et al. 2016).
Our project aims to investigate the hypothesis that surrounding biodiversity across various trophic groups is essential for preserving ecosystem multifunctionality. The project will be conducted within the Biodiversity Exploratories network (https://www.biodiversity-exploratories.de/en/), spanning long-term experimental grasslands across three different regions in Germany. The objective is to examine changes in biodiversity across trophic groups at both the local and landscape scale. Specifically, we aim to understand the impact of land-use intensification on local and surrounding diversity, the underlying mechanisms driving these changes, and how functional diversity across trophic groups influences the provision of ecosystem services.
To achieve this goal, we will collect new data on biodiversity across multiple below- and aboveground trophic groups that play a crucial role in providing essential agroecosystem services, such as soil microorganisms, arthropod herbivores, and predators. Insights from this research will contribute to our understanding of how land-use intensification affects the interplay between biodiversity and ecosystem services at both local and larger scales.
