Coral Reef Monitoring: From Cytological Parameters to Community Indices

الملخص EN

Sound-ecosystem-based management of coral reefs is largely based on indicators of reef health state.

Currently there are various ecological parameters that serve as reef state indices; however, their practical implications are under debate.

In the present study we examine an alternative parameter, the deterioration index (DI), which does not purport to replace the traditional indices but can provide a reliable, stand-alone indication of reef state.

Patterns of cytological indices, which are considered as reliable indicators of environmental stressors, have been compared to ten selected reef community indices.

The DI showed the highest correlations among community indices to the cytological indices in artificial reefs and high correlation in natural reefs as well.

Our results suggest that in cases of lacking adequate monitoring abilities where a full set of community indices cannot be obtained, the DI can serve in many cases as the preferred, stand-alone indicator of coral reef state.
