Toxicity of pesticides in lizards.

Abstract

Many threats exist to reptile populations, environmental pollutants being one of them. Lizards and other reptiles are usually not taken into consideration in environmental risk assessments, with the use of surrogate species for their estimates. Unfortunately, not all pesticides have the same effects in the reptile species and on these surrogates, birds and mammals, some being more toxic in lizards. This difference brings the need to evaluate their toxicity in lizards to safeguard its protection. Studies in the last decades involving contaminants' toxicity in lizard species have increased, thus we proposed to gather these information in this comprehensive review. Through searches in databases about the toxicity of pesticides in lizards, 16 scientific articles were found. Most studies investigated locomotor performance, histopathology, oxidative stress, neurotoxicology, and genetic damage from diverse pesticides with different modes of action. Progress has been made to acquire data on lizard ecotoxicology and more research is needed to cover more variables, such as studies in the embryologic stage and different pesticides.
