摘要: An Integrated Risk Assessment for Climate Change (IRACC) is developed and applied to assess the vulnerability of sharks rays on Australia's Great Barrier Reef (GBR) climate change. The IRACC merges a traditional change framework with approaches from fisheries ecological risk assessments. This semi-quantitative assessment accommodates uncertainty can be at different spatial temporal scales identify exposure factors, at-risk species their key biological attributes, critical habitats a`nd processes, major knowledge gaps. Consequently, provide foundation upon which develop response strategies. Here, we describe process, demonstrate its application GBR shark ray species, explore issues affecting indicates that GBR, freshwater/estuarine reef associated are most vulnerable change, driven by case-specific interactions multiple factors attributes. Changes in temperature, freshwater input ocean circulation will have widespread effects these species. Although relatively few were assessed as highly vulnerable, increases when synergies other considered. especially true coastal/inshore rays. Reducing impacts GBR's requires range including mitigating addressing habitat degradation sustainability issues. Species-specific conservation actions may required higher (e.g. whipray, porcupine ray, speartooth sawfishes) reducing mortality, preserving coastal catchments estuarine habitats, sustainability. identified many gaps concerning highlights need improved understanding biology ecology GBR.
