Early warning signals are hampered by a lack of critical transitions in empirical lake data

D. A. O'Brien, S. Deb, G. Gal, S. J. Thackeray, P. S. Dutta, S.-i. S. Matsuzaki, L. May, C. F. Clements

This study evaluates early warning signals for ecological regime shifts in lake data and finds few critical transitions, with mixed performance of prediction methods.

Planktonic functional diversity changes in synchrony with lake ecosystem state

D. A. O'Brien, G. Gal, S. J. Thackeray, S.-i. S. Matsuzaki, J. Blanchard, C. F. Clements

The paper examines the relationship between planktonic functional diversity and lake ecosystem state across five lakes, finding that FD synchronizes with state metrics but is not a reliable early indicator.
