Demographic Processes Underlying Population Growth and Decline in Salamandra salamandra

Article Abstract:

Results are presented from a 20-year study of Salamandra salamandra, focusing on recruitment and adult survival in a stable and a declining population. Adult survival was constant in the stable population over time, but a reduction in survival and constant recruitment was observed in the declining population. Use of both adult survival and recruitment data in amphibian conservation is recommended.
