In the framework of the Project ECTOPYR, model the impact of past, present and future climate change on five Pyrenean ectotherm species, on the basis of biological, ecological and climatic data generated by others tasks.


(1) Participate to the establishment of a network of observation plots of the effects of climate change on ectotherms. Propose a sampling plan. Manage the plots which will be equipped with meteorological stations and analyze the data (see (3)).
(2) Analyze of the contribution of past climate change to the distribution and spatial structure of the current genetic diversity of ectotherm species. This analysis based on an analytical model will be based on the fact that the history of climatic events can explain the current distribution and genetics of species by having greatly constrained them over time. This activity will be based on the distribution and genetic data collected for each species, as well as on the climatic and palaeoclimatic data collected during the ECTOPYR project.
(3) Analyze and 3D model the Pyrenean climate. After harvesting the climate data recorded on the ground, analyze the intra-annual variations of the Pyrenean climate in 3-dimension. The first dimension is geographic space, the second is time and the third is the vertical structuring of the climate providing climate monitoring in aquatic systems, on the ground and in the ambient air. This approach is necessary because the species of ectotherm studied occupy a wide range of habitats (from the aquatic to terrestrial system). Model the links between these 3 zones in order to be able to estimate the temperature on the ground and in water from that of the ambient air. Realize a spatial model of the current climate (ambient air) and predict the climatic conditions felt on the ground and in the water. A trainee will assist on this part.
(4) Predict the impact of future climate change on the spatial distribution of Pyrenean ectotherms. The postdoctoral program will begin by formalizing a general predictive model allowing to take into account the specificity of the species studied, which may impact their response to climate change (life cycle, ecological niche, dispersion, habitat, interspecific relationship, adaptive evolution). This step will be based on the expertise of the partners but also on the data collected and knowledge acquired on the biology and ecology of the species within the framework of this project. The model can be based on existing models (such as the simRShift model for example) that can be adapted and completed. The model will be calibrated and validated on current and / or past data. Finally, predict the temporal evolution of the distribution of the different ectotherm species studied during the 21st century (based on climate change scenarios).


- Doctorate in Ecology. A thesis dealing with the impact of global changes on biodiversity is a plus;
- Excellent knowledge of concepts / theories explaining the distribution of species and their response to a changing environment (including underlying biological mechanisms);
- Mastery of statistical and mechanistic modeling. Have already developed (or at least used) a model "process-based model" combining these two types of modeling in order to predict the response of the species to the environmental changes;
- Experience in climate modeling;
- Excellent command of programming in R. Knowledge of C ++ is also appreciated;
- Statistical analyzes;
- Analyses spatiales ;
- Encadrement de stagiaire ;
- Réalisation de relevés sur le terrain (en montagne) ;
- Rigor, organization, curiosity, individual and teamwork. The modeller will have a central place and will have to interact with the other scientists of the project in order to take into account the specificity of each species studied;
- Good level in English (a good level in French is a plus);
- Publication of work in high-level newspapers.

Work Context

This post-doctoral contract is funded within the framework of the ECTOPYR project (the ECTOthermes PYRénéens as bio-indicators of climate change), which is a across the border POCTEFA project (2014-2020), involving SETE, BOMOSA (Andorra) Association Nature Midi-Pyrénées (NMP, Toulouse, France) and the Amphibian and Reptile Recovery Center of Catalonia (CRARC, Barcelona, Spain.

Objective of ECTOPYR
The Pyrenees are increasingly affected by climate change. In this context, human societies across the borders must keep track of and adapt to the changes. ECTOPYR offers a novel and ambitious strategy in this regard; that is to use a panel of 8 ectotherm organisms as bio-indicators of climate change, occurring from low-land streams to high-altitude rock-fields. ECTOPYR will generate range maps for each model organism in order to rapidly (1) assess each bio-indicator’s response to climate change, (2) describe the natural variability of the Pyrenees’ climate over vast time scales and (3) generate modelling tools in order to anticipate the effects of climate change on each model organisms. These advances will serve decision making towards a sustainable future across the various mountainous environments, as well as thoroughly understand ecosystem functioning in the Pyrenees. These achievements will benefit environment managers, entrepreneurs, the scientific community as well as the general public. ECTOPYR will be a stepping stone towards a sustainable future in the Pyrenees, and will make people, managers and communities feel and work closer together.

General context
Historically, the planet Earth has undergone many climate changes impacting biodiversity and its functioning as a whole. The modeling action of the ECTOPYR project aims to understand and predict the impact of past, present and future climate change on five species of ectotherms (3 species of lizards, the viperine water snake and a newt). This objective is transversal to all the actions of this project since the modeling action will use all the biological, ecological and climatic data acquired in actions 3 to 7 for the parameterization of analytical and predictive models of the genetic structure and spatial distribution of the studied ectotherms at different time steps. Modeling here is a central tool to understanding the effect of past and present climatic changes on the current viability of Pyrenean ectotherms; in order to predict their future in the face of expected climate change according to the climatic scenarios defined by the Intergovernmental Panel on Climate Change (IPCC). The models will have to be innovative in order to integrate the biological mechanisms responsible for the response of species to climate change (e.g. interspecific relations and adaptive evolution). The applied purpose of this action is to provide nature and territorial managers and decision-makers with a spatio-temporal vision of the future sustainability of ectotherm species, which can be integrated into the management and current conservation of their populations and habitats whose long-term vision is sometimes lacking or at least is based on partial knowledge.
Supervision: The selected candidate will be supervised by Jean CLOBERT (head of the modeling axis of the ECTOPYR project) and Fabien AUBRET (head of the ECTOPYR project).
