متن کاملEffect of rainfall interannual variability on the stability and resilience of dryland plant ecosystems
[1] Positive feedbacks between vegetation and soil moisture may induce, in arid ecosystems, the emergence of two alternative stable states, corresponding to bare and completely vegetated soil. A new analytical model is developed to investigate this behavior and to study the effects of interannual rainfall variability on the dynamics of bistable ecosystems. When dichotomic Markov noise is used t...

Hydroperiod regimes, e.g., percentage of time a site is inundated, exert critical control in...
