The biogeochemical cycles of macronutrients (e.g. C, N P) and trace metals (e.g. Fe, Zn, Mn) can no longer be studied in isolation: they are tightly interwoven, often through microbial metalloprotein-based processes that link availability, speciation, and recycling of multiple elements simultaneously. Understanding the spatial and temporal dynamics of these interconnections, especially in the context of anthropogenic nutrient inputs, is crucial for predicting and constraining large-scale biogeochemical patterns.
