Agro-chemical inputs and fauna in New Aquitaine
Within agricultural landscapes, biodiversity is exposed to a multitude of agrochemical inputs. In addition to dramatic lethal effects, these substances are also known as endocrine disruptors that affect the functioning of organisms. We are examining the effects of these substances in ubiquitous species: passerines, amphibians present both in agricultural areas and in a priori more preserved environments such as forests. The passerines are subjected to these phytosanitary products via their diet throughout their life cycle. Amphibians, for their part, are subjected to these molecules mainly during their larval life. Thanks to these studies we show that these species are contaminated by agrochemical products and their residues. This contamination results in disturbances that influence the development, morphology, reproduction and survival of the species under consideration. Above all, our studies show that very low doses of these products are sufficient to disturb these wild organisms.
