Food handling by the gregarious Mediterranean water shrew Neomys anomalus
1999
Rychlik, L. (Polish Academy of Sciences, Bialowieza (Poland). Mammal Research Inst.)
Foraging behaviour of gregarious Mediterranean water shrew Neomys anomalus was investigated in 7 individuals. Shrews were tested individually and in a 4-animal-group in a terrarium. Shrew behaviour was recorded in darkness using 2 infra-red sensitive video-cameras. Two experimental variants, with and without natural structures in the terrarium, were established. When foraging individually, N. anomalus consumed only few food portions at the places of finding. Shrews hoarded most food in the nest and/or in hiding-places and ate it under cover. The presence of natural structures caused hoarding and eating of food in scattered hiding-places, instead of carrying it to the nest. During group foraging, N. anomalus did not hoard food communally, and preparation of individual stores almost ceased. In all tests, they ate successively more food items at the places of finding as the duration of foraging increased.

Food composition of Abramis brama was studied in the shallow, meso-eutrophic Hamry reservoir (Czech Republic). Fish were sampled during the daytime in the pre-spawning period (April), the post-spawning (June), summer (July) and autumn (October) in 2011. The bream sampled comprised two main size groups: small (124-186 mm) and large (210-315 mm) standard length. Twenty specimens of each size group (except April - 40 large fish) were taken for analysis on each sampling occasion. Food composition was evaluated using gravimetric methods. Over the whole season, detritus and aquatic vegetation were the dominant dietary items taken. During summer, the diet of large bream comprised mainly aquatic vegetation. Benthic macroinvertebrates and zooplankton formed a minor part of bream diet over the whole season. Specific food habits of bream could be explained by specific conditions within the reservoir and available food resources.

Food storage, prey remains and notes on occasional vertebrates in the diet of the Eurasian water shrew, Neomys fodiens
2002
Haberl, W.
The food remains of Neomys fodiens (particularly trichopteran larvae, Gastropoda and Amphibia) found on the banks of ponds and small creeks in Lower Austria are described. Characteristic bite marks, the manner of opening the cases and shells, as well as data on feeding patterns are presented. Food caches mainly consisted of caddis fly larvae and snails, but also contained non-palatable items which shrews apparently had confused with real prey and retrieved. The composition of the caches varied seasonally, showing a marked mid-summer decline and a shift in the proportion of Trichoptera and Mollusca in late summer and autumn. Shrews employed particular methods when breaking snail shells and opening caddis fly cases, and in the consumption of vertebrate carcasses.
