Glyphosate in the Iberian Peninsula: Evaluating risks to Iberian wildlife.

Glyphosate [N-(phosphonomethyl)glycine] (GlyP) is an herbicide extensively used worldwide, including the Iberian Peninsula. It is mainly used in agricultural landscapes but also in urban areas, in railways, and even in water bodies. Despite glyphosate's large use, there is a paucity of research on its exposure and its potential effects on wildlife living treated environments. In recent years, an increasing number of studies have warned about the effects of this herbicide namely, on oxidative stress, and on liver and kidney in different taxa. Additionally, some studies also suggested endocrine disruption capacity in reptiles or genotoxicity in fish. Most of these studies have been carried out on experimental animals, in laboratory conditions, so the real exposure and potential effects on wildlife is largely unknown. In this context, this review is intended to help understand the ecological consequences that glyphosate may be exerting on wildlife that inhabit the Iberian Peninsula.
