摘要: Otters (Lutra lutra) are found in aquatic environments. This study, however, differences the use and importance of patches at different moments otter life cycle. We studied five natal dens 38 rearing sectors small cubs Mediterranean freshwater habitats southwestern Europe. The results show a strong relationship between presence such availability food complex dens. Females with selected deepest widest stretches, more ponds calm wa- ters, greater abundance potential used Some were for generations. Our highlight certain stretches breeding otter. Conservation these areas should be basic tool management species as
