Diversity of Vegetation Patterns and Desertification

TLDR
A new model for vegetation patterns is introduced that predicts transitions from bare soil at low precipitation to homogeneous vegetation at high precipitation, through intermediate states of spot, stripe, and hole patterns and predicts wide precipitation ranges where different stable states coexist.
Abstract
A new model for vegetation patterns is introduced. The model reproduces a wide range of patterns observed in water-limited regions, including drifting bands, spots, and labyrinths. It predicts transitions from bare soil at low precipitation to homogeneous vegetation at high precipitation, through intermediate states of spot, stripe, and hole patterns. It also predicts wide precipitation ranges where different stable states coexist. Using these predictions we propose a novel explanation of desertification phenomena and a new approach to classifying aridity.

Self-Organized Patchiness and Catastrophic Shifts in Ecosystems

TL;DR: A review of recent studies on various ecosystems that link self-organized patchiness to catastrophic shifts between ecosystem states and the implications for management and recovery strategies for such ecosystems.

Regular pattern formation in real ecosystems

TL;DR: This work provides a conceptual framework explaining how scale-dependent feedback determines regular pattern formation in ecosystems, and how this affects the response of ecosystems to global environmental change.

Self-organization of vegetation in arid ecosystems

TL;DR: The results show that self-organized vegetation patterns observed in arid ecosystems might all be the result of spatial self-organization, caused by one single mechanism: water infiltrates faster into vegetated ground than into bare soil, leading to net displacement of surface water to vegetated patches.

Generic Indicators of Ecological Resilience: Inferring the Chance of a Critical Transition

TL;DR: An emerging family of methods for quantifying resilience on the basis of observations based on the phenomenon of critical slowing down, which implies that recovery upon small perturbations becomes slower as a system approaches a tipping point, is described.

Ecosystem Engineers: From Pattern Formation to Habitat Creation

TL;DR: A mathematical model is developed for a pair of ecosystem engineers commonly found in drylands: plants forming vegetation patterns and cyanobacteria forming soil crusts that highlights conditions for habitat creation and for high habitat richness, and suggests a novel mechanism for species loss events as a result of environmental changes.
