Common toads (Bufo bufo) are facing a widespread decline, which is expected to affect ecosystem functions and services. Few studies have suggested an impact of various agricultural contaminants, including veterinary drugs and pesticides. This study aimed to evaluate the effects of residues of major drugs and pesticides on Common toad populations.  Leer más.

Human influences on nature are the most important factor behind the current decline in biodiversity, forming the foundation of the ongoing sixth mass extinction event. It also includes the decline of widespread and thus common species. Leer más.
