Nonlinear ecosystem threshold boundaries define ponds

Claim that ecosystem structure and function shift nonlinearly at thresholds of surface area, depth, and emergent vegetation cover, defining boundaries between ponds, lakes, and wetlands.

Evidence Quote

“Ecosystem structure and function shift at boundaries of 3.7 ha surface area, 5.8 m depth, and 13.4% emergent vegetation cover, helping to quantitatively define ponds.”
