Spatiotemporal Variation of Small Mammal Communities in Commercial Orchards across the Small Country

The diversity of small mammal communities is a measure of the sustainability of habitats, especially agricultural ones. Based on 2018-2020 data from 18 sites in Lithuania, we analysed factors related to diversity of such a community, specifically the relative abundances and proportions of common vole, striped field mouse, yellow-necked mouse, and bank vole. We assessed the influence of location (central, northern, eastern, southern, and western parts of the country), habitat type (orchards, berry plantations, control habitats), the year and season. The model explained 14.8-33.4% of the listed parameters with p < 0.005 or higher, with the exception of the dominance index and the proportion of the common vole. Time factor (year and season, p < 0.001) and site location (p < 0.05) had the highest influences, while that of habitat type was less significant. The results of this and the former research suggest that commercial orchards play a role in maintaining the diversity and abundance of small mammal communities in the agrolandscapes.
