Amphibians epitomize the modern biodiversity crisis, and attract great attention from the scientific community since a complex puzzle of factors has influence on their disappearance. However, these factors are multiple and spatially variable, and declining in each locality is due to a particular combination of causes. This study shows a suitable statistical procedure to determine threats to amphibian species in...
The purpose of this study was to understand the differences in tolerance to ammonium nitrate in four Iberian amphibians. Results showed a negative effect on amphibian survival and larvae total length. Three different tolerance groups on amphibian survival were established. The two first groups showed a higher reduction, around 90% and between 70 and 80% after 96 h exposition at the maximum concentration tested (...
