Species composition of Ground beetles (Coleoptera, Carabidae) in Saransk
In 2008, 2009, 2011, 2013, 2014-2016, fauna of Ground beetles have been investigated in Saransk (Republic of Mordovia, Russia). According to our data and literature, it is presented by 154 species from ten subfamilies. Of them, two species ( Bembidion minimum (Fabricius, 1792) и Acupalpus elegans (Dejean, 1829)) are new for the Republic of Mordovia. Agrotechnogenic zone (68.8% of total species composition in the Saransk) includes highest number of species, residential zone (39.6%) is presented by lowest number of species. Proportion of multizonal beetle species was significant: 24.0%. We conducted comparison of species composition in different zones. As a result, two main clusters were determined. Very high values of Sorensen index was between industrial and residential zones, and between park-recreational and agrotechnogenic zones. According to the natural range type, we determined three groups: European-Siberian (35.9%), Trans-Palearctic (31.4%) and European-Mediterranean (13.7%). According to ecological preferences, we determined 11 groups of Ground beetles. Of them, highest number of species is presented in following groups: forest (28.8%), meadow- field (23.5%), forest-marsh (10.5%) and meadow (10.5%) groups.
