Modelling the demography of key species: population viability analysis

The acquisition of long time series on demographic parameters of different key species enables the development of robust population viability models (PVAs). This type of models was applied for the first time to the red gorgonian Paramuricea clavata in Dr. C. Linares’ PhD. The PVA was used to explore possible effects of recurring strong disturbances and also to demonstrate the effects of management actions on diver’s visits on the viability of gorgonian populations. At present, the same kind of models are being developed for the red coral Corallium rubrum. The experience will be used to extend this type of model to other MedRecover model species.
