This paper introduces an unsupervised method to detect and classify collective behavior in complex systems using diffusion maps and covariance analysis, applied to fish schooling data.

The paper challenges the Redfield-Tyrrell paradigm by showing that nitrogen, phosphorus, and iron can all limit primary productivity, depending on regional supply-demand ratios.

This paper explores how complex adaptive systems frameworks improve understanding of marine ecosystems' emergent patterns, critical transitions, and cooperative behavior, and their application to ecosystem management.
