Open AccessSlow Recovery from Local Disturbances as an Indicator for Loss of Ecosystem Resilience
A range of indicators have been proposed for identifying the elevated risk of critical transitions in ecosystems. Most indicators are based on the idea that critical slowing down can be inferred from changes i...

Open AccessBistability, Spatial Interaction, and the Distribution of Tropical Forests and Savannas
Recent work has indicated that tropical forest and savanna can be alternative stable states under a range of climatic conditions. However, dynamical systems theory suggests that in case of strong spatial inter...

Open AccessAlternative Stable States Driven by Density-Dependent Toxicity
Many populations are exposed to naturally occurring or synthetic toxicants. An increasing number of studies demonstrate that the toxicity of such compounds is not only dependent on the concentration or load, b...

Open AccessOmnivory by Planktivores Stabilizes Plankton Dynamics, but May Either Promote or Reduce Algal Biomass
Classical models of phytoplankton–zooplankton interaction show that with nutrient enrichment such systems may abruptly shift from limit cycles to stable phytoplankton domination due to zooplankton predation by...

Open AccessEffects of Submerged Vegetation on Water Clarity Across Climates
A positive feedback between submerged vegetation and water clarity forms the backbone of the alternative state theory in shallow lakes. The water clearing effect of aquatic vegetation may be caused by differen...

Open AccessPulse-Driven Loss of Top-Down Control: The Critical-Rate Hypothesis
In systems ranging from lakes and woodlands to coral reefs, the long-term ecosystem state may often be determined largely by rare extreme events such as wet ENSO years, droughts, or disease outbreaks. Such eve...

Open AccessShallow lakes theory revisited: various alternative regimes driven by climate, nutrients, depth and lake size
Shallow lakes have become the archetypical example of ecosystems with alternative stable states. However, since the early conception of that theory, the image of ecosystem stability has been elaborated for sha...

Open AccessA Theory for Cyclic Shifts between Alternative States in Shallow Lakes
Some shallow lakes switch repeatedly back and forth between a vegetation dominated clear-water state and a contrasting turbid state. Usually such alternations occur quite irregularly, but in some cases the swi...
