I am a conservation biologist interested in the human pressures on biodiversity (i.e. communities, functional traits, behaviour). I try as much as possible to make my work applied in order to propose solutions to limit human's footprint on ecosystems and understand what are the most effective possibilities for change in our society today.
My work focuses around several major themes:
The biodiversity-farming landscape relationship
I mainly focused on agricultural practices linked to inputs and tillage and their effects on bats and birds. In particular, I work on small changes realist for farmers in conventional farming which generate strong ecological gains for biodiversity, by studying farming systems that do not result in yield losses. I also work on landscape ecology to assess effectivness of changes in agricultural systems (practices, agroecological infrastructures and their management...) according to landscape composition with the aim to optimize conservation measures.
Linked with questions above, I also work on the ecological offsetting and ecological equivalence in farming contexts, which is a particularly applied subject that aims to (i) quantify the habitat losses generated by any development project -often on agricultural lands- to make them compensable and (ii) to find several equivalent alternatives in terms of biodiversity gains, in order to facilitate the implementation and to contextualize offsetting, and hence avoid blocking situations.
The impact of wind energy on biodiversity
I am specifically investigating a type of impact that has so far been ignored by assessment impact studies and the environmental authority, habitat loss by revulsion. I also work on metadata needed in French environmental assessment/monitoring studies to answer a wide range of questions, and how standardize the data transmitted by the consulting offices at national scale.
The artificial light at night (ALAN)
For this theme my work focuses mainly on the spatial variation of articifial light effects on bats as a function of the landscape context, as well as on changes in bat behaviour in relation with light parameters (orientation, intensity, spectra composition...). I am specifically studying light-induced changes in bat flight behaviour, their reactions when passing light halo, in term of flight trajectory, flight speed, acoustic behaviour. My research take place in habitats of high importance such as wooded edges or rivers, with the aim to highligh changes in the use of ecological corridors for moving and foraging, and ultimately impacts on functional connectivity of lit landscapes.
Bat monitoring methods
Linked with all previous themes above, I think a lot about the methods we use to track bats, particularly the acoustic biases that can affect our results and the most optimal experimental designs to answer a specific question. In particular, I am carrying out methodological developments to take into account the bias due to automated identification errors produced by identification algorithms - which have become a key tool in this period of big data.
Anthropogenic pressures on which my research are rooted often involve to work directly with stakeholders, in order to understand the social levers to transfer my research into the real life, seeking the best trade-offs to prevent this new knowledge from ever being useful in halting the decline of biodiversity.
