Behavioural markers

Developments of automatized recordings systems of behavioural patterns make it now possible to quantify accurately behaviours. Particularly, video-tracking techniques enable to determine individual performance. In this framework, we are developping behavioural markers that can be used to determine toxicity of chemicals at environmental concentrations but also to determine the persistence of behavioural integrity of organisms in varied conditions. On another hand, we use other ethometric methods to quantify more complex behavioural endpoints, such reproductive and feeding behaviours.


Reproductive tactics

From one hand, courtship behaviour is involved in partner and species recognition. On another hand, behavioural plasticity in contrasted environments can explain diversity of patterns. In this context, we use high-tech softwares that allows to synchronize video flows to behavioural sequencing across time and thus to obtain very detailed quantitative data on behavioural interactions. In fine, we observe reproduction in the field and we combine such natural patterns to causal explanations drawn from laboratory work on mating behaviour, including reproductive rates.



Optimal foraging

Optimal foraging is a key of individual success. it depends of species-specific strategies but also of individual tactics in being a response to resource disponibility and heterogeneity. We used amphibian-friendly techniques to determine feeding habits both in natura and in the lab. We specially focus on trophic specializations and resource partitioning, with also an interest in terms of energy acquisition.
