Trophic links and interspecific competition for food insectivorous mammals of the upper Pechora region
Studied the competitive relationships for food resources five species of insectivores (lesser, Laxmann's, even-toothed and the common shrew, european mole) from the region of the Pechora-Ilych nature reserve. Just processed 774 of the stomach. Sex differences in the diet and average common shrews are absent. Age differences are a higher percentage of earthworms in the diet of overwintered individuals. Species of similar sizes have similar diets. When you reduce body weight less is eaten by earthworms and insect larvae that live in soil depth, while increasing content in the diet of invertebrates that live on the surface or at shallow depth in the litter. In addition to the "longline" is present and the dimensional division of the food niches. Small shrew catch small invertebrates are of particular interest for larger shrews.
