Research facilities (CEREEP)

 

Our experimental facilities and natural populations are located at the Research Centre for Experimental and Predictive Ecology (CEREEP-Ecotron IleDeFrance) in Foljuif nearby Paris (Ecole Normale Supérieure, Seine et Marne, France). This field station is located in the vicinity of the Fontainebleau's forest and can be reached by car or train from Paris. The field station has approximately 2000 m2 of laboratory and office space and 80 ha of open field areas for ecological studies. The first experimental enclosures for lizards were designed and built by Jane Lecomte and Jean Clobert in 1992 and the site has expanded continuously since then. The CEREEP is funded by the Région Ile de France , the CNRS and the ANR, and receives continuous support from the Ecole Normale Supérieure

Outdoor enclosures and natural populations

We use large outdoor enclosures to manipulate entire populations of the common lizard - a native lizard species from Europe. The outdoor enclosures are closed with plastic walls and are approximately 100 m2 large. This is enough space to hold a small population of common lizards of around 20 to 30 subadults and adults. The enclosures are located in a natural meadow habitat and have rock and wood piles that provide shelters and basking places for the lizards, large plastic tanks to collect water and a net that protects the populations from avian predation. The lizard-proof plastic walls are buried ca 40 cm deep into the ground and are approximately 60 cm high. Natural food and sunlight are available for lizards. We are currently using 35 such outdoor enclosures and can also use several other smaller oudoor cages and large plastic containers.

The station also hosts 80 ha of natural habitats that are used by 8 species of lizards and snakes. These species can also be found in natural areas nearby.

Laboratory space

We have one laboratory room, approximately 25 m2 large, where we can conduct a wide range of measurements and some behavioral observations. The room also offers space to run standard laboratory protocols (blood sampling, immune assays, injections ...) and has storage space for our laboratory equipments (microscopes, centrifuges, visible and UV digital cameras, spectrophotometer, computers...). Our laboratory is equiped with treadmill, racetrack, a QuBit respirometer (open-flow, 7 tracks multiplexer with CO2/O2 sensors), and OceanOptics spectrophotometers.

Breeding facilities

As part of our standard monitoring program and experiments, we maintain lizards in the laboratory for short time periods, usually over one to two months. For this aim, we have two separate rooms, each approximately 30 m2, which allow to store between 500 and 1000 individual lizards. The lizards are maintained inside individual plastic cages provided with a warm spot, free access to standing water, UV light and a shelter. Room temperature can be controlled and water and food and water are provided inside each cage according to the best standards. Animals are regularly inspected and the breeding facilities is under strict sanitary control.
