Impact of quarrying on genetic diversity: an approach across landscapes and over time
Abstract Land conversion is one of the major global
changes that threaten population viability. As with many
industrial activities, quarrying highly modifies land cover,
destroying previous habitats but also creating new conditions
potentially supporting functioning and connectivity of
pioneer species. Using a multi-landscape and -temporal
approach, we assessed the impact of quarrying on the
genetic diversity of two amphibians with contrasted ecological
constraints: the common toad (Bufo bufo) and the
natterjack toad (Bufo calamita), favouring vegetated
and pioneer environments, respectively. The study was
