Communities of small terrestrial mammals in the surroundings of Vltava river
ŠPILAUER, Tomáš
The bachelor thesis is dealing with the influence of watercourse on the biodiversity of small terrestrial mammals in landscape near river Vltava in South Bohemia. The theoretical part consists of literally review about diversity, ecotones, biocorridors, watercourses and about ecology of small terrestrial mammals. The aim of the practical part is to compare biodiversity, abundance of small mammals and compare impact of watercourses on small mammals. During 2021 vegetation sesion the CMR method with ear tags was used. During three-days long captures were laid 25 traps in 5 metres distances in each of the three studied biotope lines (Forest, Meadow, Shore). In total 136 individuals of small mammals were captured. The species, sex, weight, foot lenght and age of captured mammals were determined. Two species of small terrestrial mammals were captured (Myodes glareolus, Apodemus sylvaticus). In total of all 136 individuals were captured: 51 individuals of Myodes glareolus and 75 individuals of Apodemus sylvaticus. Significant difference in quantity was in the line Forest where were captured 23 Myodes glareolus and 45 Apodemus sylvaticus. In the line Forest were captured 68 individuals in total and the same number was captured in the line Shore (also 68 individuals). In the Meadow line no individual was captured.
