BEHAVIOURAL ECOLOGY OF SHARKS: from individual behaviour to population structure

IMG_1781

Most of reef sharks are marine vertebrates that get closed to the marine mammal model with low productivity, viviparity, long gestation periods, high longevity, late maturity, small populations and large individuals. They give birth to live young, but they leave them without taking care of as marine mammals do. As they have sedentary juveniles and adults that can possibly migrate for dispersal, reef sharks differ from most coral reef fish that have sedentary adults and disperse via larvae, and thus form an original biological model.

Improved knowledge of the organisation of reef shark populations will help to investigate the degree of vulnerability of these populations and to design conservation strategies.

My main research interests are the following:

1- Habitat use, home range and site-fidelity of sharks.

2- Social networks and social behaviour in reef sharks

3- Breeding patterns and connecticity in shark populations.

4- Impact of « shark feeding » activities on shark behaviour and ecology.

5-Trophic ecology of elasmobranchs

KEY WORDS: Reef sharks, genetic, acoustic tracking, movements, social organisation, vulnerability, impact of shark feeding activities.
