Conservation of marine mammals

I started working with marine mammals when Bénédicte Madon spent some time with us for her PhD. She was studying humpback whale in New Caledonia. We ended up suggesting a few improvements in the way abundance is estimated when i) two sources of data are available (here, but see here) and ii) when individuals pass through the sampling area and do not belong to the resident population (transience, see here and here for a similar work on the population growth rate by Florian Orgeret). Besides abundance, we recently proposed as part of Marine Desprez PhD an application of hidden Markov models to estimate recruitment in elephant seal in presence of uncertainty on the breeding states (here).

Lastly, I’ve become more and more interested in trying to make sense of opportunistic data which are often collected on marine mammals, mainly photo-identification on the Risso’s dolphin near Montpellier (Anna Lenoël master internship) and monk seals in Greece. This is part of a general reflection within the Cisstat group and the GDR EcoStat.

I’m also working with Giovanni Bearzi, Silvia Bonizzoni and Nina Santostasi from Dolphin Biology and Conservation on the conservation of dolphins in the Gulf of Corinth, Greece.

This is joint work with Hélène Labach, Léa David, Nathalie DiMéglio and colleagues from GIS3M, Claire Garrigue from Opération Cétacés and Alexandros Karamanlidis and colleagues from MoM.
