Humans and climate affect ecosystems and their services, which may involve continuous and discontinuous transitions from one stable state to another. Discontinuous transitions are abrupt, irreversible and among the most catastrophic changes of ecosystems identified. For terrestrial ecosystems, it has been hypothesized that vegetation patchiness could be used as a signature of imminent transitions. Here, we analyse how vegetation patchiness changes in arid ecosystems with different grazing… 
Interspecific facilitation and critical transitions in arid ecosystems
The human impact on the climate system and on ecosystems has rapidly increased over the last century. Moreover, forecasts by global climate models predict that increasing temperatures and more
Spatially heterogeneous pressure raises risk of catastrophic shifts
Ecosystems may exhibit catastrophic shifts, i.e. abrupt and irreversible responses of ecosystem functions and services to continuous changes in external conditions. The search for early warning signs
Modelled responses of the Kalahari Desert to 21st century climate and land use change
The authors' simulations suggest that whilst the study sites will experience some climatically-induced landscape change, the impacts of climate change alone on vegetation cover and sediment mobility may be relatively small, however, human activity could strongly exacerbate certain landscape trajectories.
Desertification Transition in Semi-arid Ecosystems and Directed Percolation
Regime shifts in ecosystems caused by climatic or anthropogenic factors can happen on a relatively short timescale with relevant economic and social effects, a consideration which motivates the large
Empirical evidence reveals the phase diagram of vegetation patterns in Mediterranean drylands
Using satellite images of a typical semiarid shrubland in Southern Spain, vegetation data is gathered and it is argued that vegetation cover can be interpreted by means of a percolation process and the hypothesis of universality classes to sort different drylands is supported.
Microclimate feedbacks sustain power law clustering of encroaching coastal woody vegetation
It is shown that in a North American coastal ecosystem where woody plant encroachment has been happening, the size distribution of woody patches follows a power law when the system approaches a critical transition, which is sustained by the local positive feedbacks between vegetation and the surrounding microclimate.
Effects of precipitation intermittency on vegetation patterns in semi-arid landscapes
Intermittent percolation and the scale-free distribution of vegetation clusters
It is shown that environmental temporal variability -- a well-recognized feature of semiarid environments -- promotes in a robust way the emergence of vegetation patches with broadly distributed cluster sizes, which supports the idea that environmental variability plays a key role in the formation of scale-free vegetation patterns.


Mussel Disturbance Dynamics: Signatures of Oceanographic Forcing from Local Interactions
It is shown that the mussel bed can go through phase transitions characterized by a large sensitivity of mussel cover and patterns to oceanographic forcings but also that criticality is observed over wide ranges of parameters, which suggests self‐organization.
Catastrophic shifts in ecosystems
Recent studies show that a loss of resilience usually paves the way for a switch to an alternative state, which suggests that strategies for sustainable management of such ecosystems should focus on maintaining resilience.
Biological Feedbacks in Global Desertification
Studies of ecosystem processes on the Jornada Experimental Range in southern New Mexico suggest that longterm grazing of semiarid grasslands leads to an increase in the spatial and temporal heterogeneity of water, nitrogen, and other soil resources, which leads to the desertification of formerly productive land.
Ecosystem Service Supply and Vulnerability to Global Change in Europe
A range of ecosystem models and scenarios of climate and land-use change to conduct a Europe-wide assessment of ecosystem service supply during the 21st century, finding that many changes increase vulnerability as a result of a decreasing supply of ecosystem services.
Association between competition and facilitation processes and vegetation spatial patterns in alpha steppes
On moderate slopes where Stipa tenacissima cover was high, the selforganization of some of the typical species of semiarid Mediterranean matorral species was negatively correlated with StipA cover, and facilitation processes were manifested by the developmental stability increases under the Stip a canopy.
