Abstract

The study of the species composition, biological and ecological features of small mammals was carried out for five years (2018–2022) in the surroundings of the village of Rozsohuvata (Kharkiv Oblast, Ukraine). During the study period, nine species of mouse-like rodents and three species of insectivorans were detected. The research area is represented by a ravine-beam system, agrocoenoses, field-protecting forest strips, riparian vegetation around artificial reservoirs and streams, dry meadows, and pastures. Trappings of small mammals were carried out on thirty lines of traps. During the entire period of trapping, the dominant species was Sylvaemus uralensis and in some seasons Sylvaemus sylvaticus dominated. Starting from 2018, the relative abundance increased in autumn, reached a peak in 2020 and declined in the following years. In general, 2019 was the year of maximum abundance and most species were recorded in the summer of this year. The greatest number of species was found in the ecotone between riparian vegetation and field (10 species), as well as in the area of the multi-grass steppe in the beam (8 species). The eurytopic species include Sylvaemus uralensis and Sylvaemus sylvaticus, whereas the stenotopic species is Mus spicilegus. According to the obtained abundance scores, only one species—Myodes glareolus—occurs randomly, whereas the rare species here are Mus spicilegus, Sorex minutus, and Crocidura suaveolens. Six species are non-abundant: Apodemus agrarius, Sylvaemus tauricus, Mus musculus, Microtus levis, Cricetulus migratorius, and Sorex araneus. Only Sylvaemus sylvaticus belongs to common species, and only Sylvaemus uralensis is abundant. It should be mentioned that Cricetulus migratorius, which usually belongs to the category of random or rare species, turned out to be non-abundant in the study region, and it was recorded regularly in almost half of the studied biotopes. Myodes glareolus, which usually prefers oak forest, was extremely rare. The abundance of Apodemus agrarius, which usually belongs to common species in river valleys, was also low. Sylvaemus showed greater ecological valence, dominated in abundance and inhabited most biotopes, except for Sylvaemus tauricus, which began to occur only in the last two years and mainly in forest strips.

Key words

small mammals, relative abundance, biotope preference, species composition, long-term monitoring, abundance category.
