Lucie Penin, Visiting Postdoctoral Fellow

Lucie is currently a postdoctoral researcher at “Biologie et Ecologie Tropicale et Méditerranéenne” laboratory at EPHE, Perpignan, France. She recently defended her PhD. on effect of recruitment and post-settlement events on coral population maintenance in French Polynesia. Her research topics encompass coral population dynamics and effects of disturbances on coral communities..


In order to understand the processes contributing to maintenance of coral populations on small isolated reefs, I studied spatial and temporal variation on coral recruitment and the influence of these patterns on adult assemblages. Spatio-temporal variability of recruitment was characterized at an insular scale around Moorea over five years and at a regional scale in the Society archipelago (French Polynesia) over one year. This technique enabled a muti-scale spatio-temporal analysis of the data. Benthic mortality of recruits and juveniles was also quantified around Moorea and the major factors causing mortality were identified. These results emphasize the importance of post-recruitment events in structuring and maintaining adult assemblages, regardless of the spatio-temporal scales considered. However, for some taxa, spatial patterns of adult populations around Moorea are mainly driven by spatial variability of recruitment during previous years. These results illustrate the importance of varied life history traits in mechanisms of population maintenance.
