RESEARCH
My main research line is the study of social insects social organization. Social insects live in colonies with one or a few reproductive females that mate with one or a few males. While nestmates generally cooperate in the realization of domestic tasks such as food collection, brood rearing etc, they may enter in conflict for reproduction. Part of my research aims at determining the signals that are used by social insects to recognize each other and to demonstrate their reproductive state. I am also interested in the effects of social organization and mode of dispersal at population level. Currently, I mostly focus my research on species that disperse by colony fission, Aphaenogaster senilis and Cataglyphis floricola.
My second line of research concerns ant-plant relationships. I started studying seed-dispersal by ants in 2002 using the hellebore as a model system. I currently have a project in French Guyana on myrmecophytes. These are plants that present special structures (domaties) that are inhabited by ants. In exchange of obtaining a nesting site, ants defend these plants against herbivores. The project 2ID is financed by the CNRS and involves several researchers from the University of Toulouse, Clermont-Ferrand and Quebec.

I started my research on the key factors affecting population abundance of wild rabbits that were declining in the Iberian Peninsula (5-8,11). Of course, many people think on rabbits as pests. The interest of the interferences between opposite goal managements (save vs control rabbits) lead me to work on GMOs: rabbit viruses are being genetically modified to be used as either vaccines or (virus-mediated) inmunocontraception devices (3-4,14). Vaccinal GM rabbit virus is near to be released, with the obvious catastrophic consequences for many countries. Alive viruses don't know about borders, neither GM insects, under research for the control of diseases, i.e. malaria. Current national and international policies are not effective to control such releases (17,20). With Ben Gilna we are exploring some other possible options of control.
With Franck Courchamp (University of Paris Sud XI) I work on Allee effects (AE) and the conservation of endangered species. Population benefits resulting from cooperation between individuals could lead to the extinction of populations at low numbers. We showed how multiple AEs in different fitness traits are common, and could interact synergically (10,12). We also showed how human value for rarity could cause AEs, the anthropogenic AE, which concerns endangered species (9,13,24-25). Some more insight on how to overcome AEs will come soon.
The collaboration with Stephane Caut is been fruitful, resulting in a big amount of scientific literature on different applications of isotopes, from methodological experiments to reviews and applications to invasive species or endangered species (15-16,18-19,21,23). Discussions to deep in other methodological concerns will follow very soon.
Last but not least I explore now invasive ant species, i.e. the Argentine ant, at Doñana National Park with Xim Cerdá and Raphael Boulay. Linking the study of ant communities, natural and invaded, with the whole ecosystem, using stable isotopes techniques.

RESEARCH
My research has been focused on how individual behavior can impact the dynamics of populations and communities, with a particular emphasis on host-pathogen interactions and interspecific competition. I have addressed this topic using numerous study systems including hantavirus/small mammals in Utah (Ph.D. project with Denise Dearing, University of Utah, Salt Lake City U.S.A.) (1-5), ant communities in North America (Ph.D. with Donald Feener, Jr., University of Utah, Salt Lake City, U.S.A.) (7-10), and avian influenza/gulls in the Mediterranean (Postdoc with Thierry Boulinier, CNRS-CEFE Montpellier, France) (6).
Over the course of my Ph.D. work with Don Feener, I became interested in exploitative competition in ant species. Competition is considered one of the most significant influences on community structure, especially in ant assemblages. In many communities, ant species trade-off between the ability to be good discoverers, arriving at food resources first, and to behaviourally dominate them, limiting access by other species. Although the ways in which ants dominate food are well-characterized, little is known about the patterns and mechanisms of resource discovery. In my thesis, I showed that discovery ability in ants is largely determined by the individual traits of foragers. Foragers appear to enhance discovery by increasing the probability that ants will run into food resources (the “bumper-car” model of discovery) (9), utilizing such traits relatively longer legs and straighter search patterns to traverse and search the environment more efficiently (8). In contrast, evidence is limited that ants pick up on resource signals and are thus directed to food items, at least at longer ranges (7).
This work provided the basis for the postdoctoral funding I received from the National Science Foundation (U.S.A.) to investigate the effect of food availability and species removal on foraging patterns in ant communities. I am collaborating with Xim Cerda and Raphael Boulay in the implementation of this project. In particular, we are examining three hypotheses: a) mechanisms for resource discovery by ant species vary depending on resource availability; b) the dominance-discovery trade-off is present in Mediterranean ant communities; and c) resource availability and the removal of a good discoverer increases species richness and/or forager abundance by allowing the persistence of slow behaviorally dominant species. Since resource discovery is a crucial component of competition in any ant community, this mechanism-focused research is generating data that clarify how the trade-off persists and functions. Furthermore, this work examines the novel hypothesis that discovery, not dominance, drives ant assemblage composition. The species that we will be removing, Aphaenogaster senilis, was previously identified as being a good discoverer and is a species of particular interest for the research team. I am also working with Xavier Arnan and Anselm Rodrigo to examine the effects of fire on competition for resources in Mediterranean ant communities.

RESEARCH
I received a formation in evolutionary biology, and I specialized during my PhD in chemical and behavioural ecology. I am particularly interested in the evolution of eusociality, resolution of conflicts and communication in social groups.
I'm currently writing papers about the gypsy ant : Aphaenogaster senilis.
What are the proximate mechanisms promoting the large production of sterile individuals caring for offspring of other colony members? How does the queen maintain its reproductive monopoly? What factors affect larval development?
The aim of my PhD is to understand how conflicts over caste fate are resolved in the fission-performing ant Aphaenogaster senilis and what is the role of each member. I focus particularly on the chemical signals the queen uses to indicate her presence and fertility.
