“…Due to the diversity of these ecosystems, they are home to a significant species diversity of insects [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. While many insect species thrive, some forest species are on the verge of extinction due to forest degradation, pollution, fragmentation, changes in tree composition, climate change, and other factors, such as fires, tree felling, and draining [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ]. The species diversity of Coleoptera forest ecosystems is very large, and knowledge about this biodiversity is constantly being updated through the use of a wide variety of studying methods [ 17 , 18 , 19 , 20 , 21 , 22 ].…”

The possibilities of applying various methods to study Coleoptera give unexpected and original results. The studies were carried out with the help of fermental crown traps in 2018–2020 on the territory of eight regions in the central part of European Russia. The biodiversity of the Coleoptera that fall into crown traps includes 294 species from 45 families. The number of species attracted to the fermenting bait is about a third of the total number of species in the traps (this is 97.4% of the number of all of the caught specimens). The largest number of species that have been found in the traps belong to the families Cerambycidae, Elateridae and Curculionidae. The most actively attracted species mainly belong to the families Cerambycidae, Nitidulidae and Scarabaeidae. The species of these families are equally attracted by baits made of beer, white and red wines. In order to identify the Coleoptera biodiversity of a particular biotope, two-year studies are sufficient, and they should be carried out throughout the vegetation season. Especially good results can be obtained from studies of rare species that are actively attracted by such baits. It is possible to study the vertical–horizontal distribution of Coleoptera fauna in individual biotopes.

“…They significantly contribute to the biodiversity of forest ecosystems and play an important role in the functioning and dynamics of ecosystems. Among them, there are numerous predators, phytophages, as well as other groups [2][3][4][5]. The significant species diversity of beetles allowed them to occupy a variety of biotopes in all ecosystems of the globe [6][7][8][9].…”

There are few studies on the vertical distribution and seasonal activity of arthropods in open habitats (in glades) in temperate forests due to methodological problems associated with the arrangement of certain structures for trapping. However, glades in forests are places of significant biodiversity of native animals, which are attracted to such areas by the possibilities of nutrition, reproduction, and wintering. The research was carried out on the territory of the Republic of Mordovia (the center of the European part of Russia). Fermental traps (bait—fermenting beer with sugar) were used to collect Coleoptera. They were installed on a special structure at heights of 2, 4, 6, 8, and 10 m. The collections were carried out from May to October 2020 in a glade with an area of 0.93 hectares in a deciduous forest. At the end of the research, 745 specimens of 80 species were registered from 30 Coleoptera families. The greatest species diversity was recorded in Nitidulidae (11 species), Cerambycidae (10 species), Scarabaeidae (7 species), Elateridae, Coccinellidae, and Curculionidae (5 species each). The greatest species diversity (53 species) and numerical abundance were obtained at a height of 2 m, and the smallest one (16 species) at a height of 10 m. The largest differences in the Jaccard similarity index were obtained between samples from a height of 2 and 10 m. The maximum values of the Shannon index and the minimum values of the Simpson index were recorded at the height of 2 m. The most significant relative number of saproxylic species was obtained at a height of 4 m. The relative number of anthophilic species was minimal at a height of 10 m. The seasonal dynamics of Coleoptera abundance were the same at different heights and the highest abundance was observed in late May and early June. However, the seasonal dynamics were different for some Coleoptera species in the glade located and inside the forest. Our data confirm the relevance of sampling in open biotopes at different heights in the study of arthropod biodiversity.

“…In different worldwide regions, meadows are rich in perennial plant species [1] including threatened [2] and invasive [3] ones. They provide areas for the inhabitation of birds [4], mammals [5,6], reptiles [7], invertebrates [8][9][10], and others. The various meadow types have different abilities to recover after disturbance due to differences in carbon stock values [11,12].…”

The species diversity of ground beetles (Carabidae) was studied in the meadow ecosystems in the center of European Russia (Nizhniy Novgorod region and the Republic of Mordovia). Seventeen localities were studied. All meadow biotopes were divided into four types: dry meadows, dry meadows adjacent to forest shelter-belts, wet floodplain meadows, and floodplain meadows affected by livestock grazing. The highest species diversity was in dry meadows adjacent to forest shelter-belts (65 species) and wet floodplain meadows (62 species). The lowest number of species was in floodplain meadows affected by livestock grazing (24 species). Forty ground beetle species have been identified in dry meadows. Wet floodplain meadows had the highest Shannon's index, and the lowest Simpson index. The ground beetle fauna had high values of the Simpson and Berger-Parker indices in dry meadows. Only two species dominated in dry meadows, while four to seven species dominated in other habitats. According to the Jaccard similarity index, the most similar species composition of ground beetles was in dry meadows and dry meadows adjacent to forest shelter-belts. By reducing the number of species and specimens of ground beetles, trampling has a great effect on the fauna of floodplain meadows affected by livestock grazing.
