Occurrence of the insectivores and rodents of the Samarskaya Luka (Russia)

Our dataset includes 8147 records of insectivore and rodent occurrences from the Samarskaya Luka (Samara Oblast, European part of Russia). The data on 26 species (of total 28 inhabiting region) of micromammals belonging to 22 genera and 9 families are presented. The East European vole, Microtus levis Miller, 1908 is a sibling species of the common vole Microtus arvalis Pallas, 1778. In a large part of Eurasia, including the Samarskaya Luka, these two rodent species are sympatric. Therefore, our occurrence records of the common voles include those of the East European voles. The dataset summarises insectivore and rodent occurrences obtained by field studies in the territory of the Samarskaya Luka during 20-year period (2000–2020). Each occurrence record contains the species name, basis of record, geographic coordinates, coordinate accuracy, date of the record and authors of the record and species identification. All occurrence records are georeferenced. The dataset is based on research of the staff of the Institute of Ecology of the Volga River basin of the Russian Academy of Sciences and the Zhiguli State Nature Reserve. Our studies of micromammals were conducted by trap lines and observations in nature.
