Identifying and tracking individuals across time are a prerequisite to uncover key traits of their ecology behavior. However, obtaining fine-grain individual data at multiple locations, especially in aquatic environments, is challenging due trade-offs between constraints detection probabilities. Aquatic telemetry passive integrated transponder (PIT)-tagged organisms has been proposed cope with ...

Pelophylax esculentus is a hybridogenetic frog originating from matings between P. ridibundus (RR) and P. lessonae (LL). Typically, diploid hybrids (LR) live in sympatry with one of their parental species, upon which they depend for successful reproduction. In parts of their range, however, pure hybrid populations can be found. These hybrid populations have achieved reproductive independence fr...

In Germany, the pathogenic fungus Batrachochytrium dendrobatidis (Bd) was detected in 11 indigenous frog species, 4 newt species, and 1 salamander species in 64 out of the 181 locations (35%) investigated. Among the 3450 samples collected between 2003 and 2011, 284 (8.2%) were positive for Bd infections. The highest prevalences were observed in Alytes obstetricans (17.8% of individuals, 20% of ...
