Addressing Challenges in Simulating Inter–Annual Variability of Gross Primary Production
Abstract A long‐standing challenge in studying the global carbon cycle has been understanding the factors controlling inter–annual variation (IAV) of carbon fluxes, and improving their representations in existing biogeochemical models. Here, we compared an optimality‐based model and a semi‐empirical light use efficiency model to understand how current ...

Emergence of a Resource Acquisition Trade‐off at the Community Scale during Environmental Change
A four‐decadal cycle of eutrophication and subsequent re‐oligotrophication in Lake Constance led to the emergence of a strong trade‐off between phosphate and light affinity. We derive an explanation for the emergence of this trade‐off from resource ratio theory and discuss the relevance of this novel concept for trait‐based ecology.
