Research

After a PhD on the evolution of crèching behavior in gulls, I am now working in the field of conservation biology. More specifically I am working at developing regular collaborations between field practitioners and stakeholders and biostatisticians that develop methods for population monitoring and population dynamic modeling. I thus did work on :

1.    Estimating demographic parameters mainly for endangered species in the context of conservation plans

2.    Estimating the impact of perturbations or habitat alterations on these species.

3.    Evaluating and building monitoring protocols for endanger species (often rare, with small distribution or/and hard to detect) by using power tests for instance to compare the performance of several methods

4.    Developing new methods or refining existing ones when necessary

In this context I worked, and am still working, on several species such as birds (black-headed gulls, slender-billed gulls, black-billed gulls, Corsican nuthatches, woodpigeons, little bustards, bonelli’s eagles, golden eagle, grey and red-legged partridges, ptarmigans, european rollers…), reptiles (Herman’s tortoise, European pond turtle, pyrenean lizards, orsini’s viper...), amphibians (crested newt, marbled newt, yellow-bellied toad…), mammals (ibex, Pyrenean desman, wild boar, otter, bonobo…),  insects (coleopteran, grasshoppers, dragonflies…),mollusks but also more recently on plants.

All these works are conducted in direct collaboration with scientists of course but also field practitioners and stakeholders (several state organisms such as all national parks, several national reserves, the national office for hunting now French Office of Biodiversity…) but also several international, national or local NGO  (WWF, Birdlife, LPO…) and private environmental consultants (biotope, ecomed…). I am also involved in several species conservation plans (National plans for bonelli’s eagle, Hermann’s tortoise, Orsini’s viper, Pyrenean desman…). 

 

Recherche

 Après une thèse de biologie évolutive chez les mouettes et goélands (télécharger cette thèse), mon champ de recherche actuel se situe dans le domaine de la biologie de conservation. Plus précisément, il consiste à développer l’interface entre les méthodologistes qui travaillent à développer les outils statistiques pour l’étude des paramètres démographiques et populationnels et les conservationnistes ayant besoin de ces nouvelles méthodes. 

       1. d’estimer les paramètres démographiques de petites populations d’espèces à forte valeur patrimoniale et souvent fragmentées
       2.  d’estimer l’impact de perturbations ou de modification de l’habitat sur la dynamique des populations de ces espèces
       3.  d’aider à la mise en place de protocoles de suivi par la mise en œuvre de pré-études, de tests de puissance afin de déterminer quelle sera la méthode la plus adaptée à telle ou telle situation
       4.  de développer des méthodes statistiques lorsque cela s’avère nécessaire (notamment en CMR ou dans le cadre bayesien)

Ainsi j’ai pu travailler sur un certain nombre d’espèces d’oiseaux (mouette rieuse, goéland railleur, mouette scopuline, mouette de  buller, lagopède alpin, sitelle corse, perdrix grise, rollier d’Europe, papangue de la Réunion, pipit rousseline, alouette lulu), des reptiles (lézard des Pyrénées, lézard ocellé, lézard de Manapany, vipère d’Orsini, tortue d’Hermann, cistude d’Europe), des batraciens (triton crêté, triton marbré, crapaud sonneur à ventre jaune), des insectes (coléoptères, criquets, libellules), des mollusques (grande Mulette) et des mammifères (vison d’Europe, campagnol amphibie).

Tous ces travaux sont menés en collaboration directe avec des scientifiques bien sûr mais aussi des praticiens de terrain et des parties prenantes (plusieurs organismes d'état comme tous les parcs nationaux, plusieurs réserves nationales, l'office national de la chasse aujourd'hui Office Français de la Biodiversité...) mais aussi plusieurs ONG internationales, nationales ou locales (WWF, Birdlife, LPO...) et des consultants privés en environnement (biotope, ecomed...). Je suis également impliqué dans plusieurs plans de conservation d'espèces (plans nationaux pour l'aigle de Bonelli, la tortue d'Hermann, la vipère d'Orsini, le desman des Pyrénées...).
