Alternative Attractors of Shallow Lakes [PDF]
The Scientific World JOURNAL, 2001 Ponds and shallow lakes can be very clear with abundant submerged plants, or very turbid due to a high concentration of phytoplankton and suspended sediment particles. These strongly contrasting ecosystem states have been found to represent alternative attractors with distinct stabilizing feedback mechanisms.
