Current limitations of global conservation to protect higher vulnerability and lower resilience fish species

Abstract Estuaries are threatened by intense and continuously increasing human activities. Here we estimated the sensitivity of fish assemblages in a set of estuaries distributed worldwide (based on species vulnerability and resilience), and the exposure to cumulative stressors and coverage by prote...
