Interaction between tree diversity and water availability on nutrient cycling in forests

Abstract : Increasing biodiversity has been highlighted as a solution to make forests more efficient and resilient to global changes, such as drought. In this thesis, we sought to determine whether reduced water availability could have an impact on the potential effects of tree species diversity on nutrient cycling. To answer this, two experimental sites (France and Canada) that manipulate both tree diversity and water were studied. We observed that surface soil biogeochemical processes were driven by water availability, intermediate soil processes by species mixing, and nutrient use efficiency by species identity. Finally, we did not observe an interactive effect between these factors, as they were spatially and temporally separated.
