The documented and worldwide loss of seagrasses calls for effective measures to anticipate their decline and improve conservation. It has been suggested that seagrass response to increasing stress can be often non linear and show sudden decline. Ecological theory also proposes that systems close to decline become more stochastic and slow in recover...
