Abstract

The population investigated inhabits about 30 gravel bars along the Upper Isar Bavaria, Germany. The model considers the key processes affecting the survival of the metapopulation. Considering the abundance at the Upper Isar the model predicts a persistence time of about 100 years including a rough estimate of the mean flood frequency and assuming random floods. But if the floods occur regularly the population can persist a much longer period. The lack of large subpopulations or the splitting of the metapopulation into several subpopulations indicates a severely endangered state. -from English summary
