Empirical evidence on the effects of climate on the viability of common carp (Cyprinus carpio) populations in European lakes
Résumé
Climate is a major driver of species distribution and biological invasions worldwide. In this study, we combined the catches of a widespread and invasive species, the common carp (Cyprinus carpio), with climate data to assess the importance of climate variables on the ability of the species to maintain self-sustaining populations in European lakes. Data were collected on common carp populations in 378 lakes in six European countries over a 16-year period (551 sampling campaigns). All catchesoverlapped with the invasive range of the species. According to Intergovernmental Panel on ClimateChange (IPCC) climate projections, some areas where common carp currently have a low probability ofmaintaining viable populations will shift toward climatic conditions that enhance their viability and invasion potential.
