Description:

The modes and efficiency of foraging in the terrestial and aquatic habitats in water shrew Neomys anomalus Cabrera, 1907 and N. fodiens (Pennant, 1771) were compared in order to investigate if these species can avoid competition for food when they occur syntopically. Seven individuals of N. anomalus and five of N. fodiens, caught in the Białowieża Primeval Forest, were tested individually in the terrarium of size 3 x 0.5 m, containing a 0.25-m-wide 'stream' with flowing water of an average depth 25 cm. Six experimental variants, simulating different habitat conditions, were established. Each animal was tested in a given variant during 3 succeeding days for 6 h a day. In total, 738 h of shrews' behaviour were recorded in darkness using 2 infra-red sensitive video-cameras.
