Consequently, studies that only consider separable, unidirectional effects can produce divergent conclusions and equivocal ecological implications. To address this complexity, we use empirical dynamic modeling to assemble causal networks for 19 natural aquatic ecosystems N24o N58o and quantified strengths of feedbacks among phytoplankton diversity, phytoplankton biomass, and environmental factors. Through a cross system comparison, we identify macroecological patterns; in more diverse, oligotrophic ecosystems, biodiversity effects are more important than environmental effects nutrients and temperature as drivers of biomass. Furthermore, feedback strengths vary with productivity. In warm, productive systems, strong nitrate mediated feedbacks usually prevail, whereas there are strong, phosphate mediated feedbacks in cold, less productive systems. Our findings, based on recovered feedbacks, highlight the importance of a network view in future ecosystem management. 13 Published version Articolo in rivista Nature Publishing Group. 2041 1723 Nature communications Nature communications Nature communications marinamarcella.manca MANCA MARINA MARCELLA roberta.piscia PISCIA ROBERTA michela.rogora ROGORA MICHELA |
