Ethological study of sympatric species of European water shrews

A comparative study of the behaviour of two sympatric species of European water shrews, Neomys fodiens (Pennant, 1771) and Neomys anomalus Cabrera, 1907 was carried out using three methods: (1) the open field, (2) the placement of two individuals in unknown, neutral territory, and (3) the formation of model social groups. Interspecific and intraspecific bahaviour was studied and significant differences between the two species were found.
