E-mail: [email protected] Abstract: The present study compiles the results of bryophyte species inventories made at the Mordovia State Nature Reserve from 2014 till 2016. The reserve is located near southern limit of deciduous-coniferous forest subzone. In total 96% of the reserve is covered by forests, where about half are pine forests. The annotated bryophyte checklist includes 142 moss species and 23 liverwort species. The data on collecting site characteristics, habitats, substrates, bryophyte species frequency, and sporophyte presence are provided. Presented treatment is a key contribution to the bryophyte flora of Mordovia and important for the knowledge on bryophyte distribution of this forested area within strongly anthropogenically disturbed European Russian landscape.

In total 72 Folia Cryptog. Estonica 96% of the reserve is covered by forests, about half of them are pine forests. Common are pine forests with mosses, blueberry, cowberry, Cla- donia lichens, reed and Sphagnum. One fourth of all forests is covered by birch forests, often with significant amount of lime trees. The birch forests with sedge, herbs, blueberry and ferns are typical. The broad-leaved forests with lime, maple, oak, ash and elm are rather common. The mixed forests of several tree species are most typical at the reserve. The broad-leaved forests with herbs, hairy sedge and ferns frequently occur on nutrient rich soils. Broad-leaved for- ests with reed and bent-grass grow on dry, well drained soils. Broad-leaved forests with nettle occur on soils with high humidity and sufficient drainage.

In this study, we revealed invasibil- ity of fire-damaged forests at the southern boundary of the taiga zone. Area of study: The Mordovia State Nature Reserve (Central Russia). Material and Methods: Altogether, 11 square plots of each 100 × 100 m were established in different types of fire-damaged forests. To test plant invasion outside the established plots, field researches were carried out by route method in fire-damaged area of the Mordovia Reserve. Main Results: Six alien species (Erigeron canadensis, E. annuus, Oenothera biennis, Lactuca serriola, Sambucus racemosa, Viola arvensis) were registered within the established plots in 2011–2014. In addition, two alien invasive plants (Solidago canaden- sis and Bidens frondosa) were found outside these plots. No differences were detected in invasibility of the tested forest ecosystems.

Abstract While the development of the country’s national innovation system as a whole is very important and should be prioritized, its regional aspect is even more important. The specifics of the Russian Federation’s transition to an innovation-based economy is in that that, at the present time, prioritized is the need to ensure the effective development of those economy sectors that underlie the country’s specialization and may provide regional and national competitive advantages. To such sectors belong the chemical industry, machine-building and power energetics. We would like to note that initial innovation awareness indicators in the regions are comparable and do not differ greatly but the growth of activity can be observed only in some of the regions. The problem of large differentiation among the constituent entities of the Russian Federation by their level of economic development remains important and has to be dealt with.

Of these, one species of Orthoptera (Calliptamus italicus) is recorded for the first time for the Mordovia State Nature Reserve, four species (Mantis religiosa, Phaneroptera falcata, Conocephalus fuscus, Tettigonia caudata) are recently penetrated, one species (Conocephalus fuscus) is reported in the Republic of Mordovia for the first time. In the fauna of mantids and orthopterans of the Mordovia Reserve, three ecological groups were identified: polytopic, not confined to certain biotopes (14 species), hygrophilous representatives of intrazonal habitats (5 species) and xerophiles. Among the latter, there are species of extrazonal habitats (13 species) and confined to dry pine forests (7 species). The steppe group was not represented. For the three key habitats with the largest number of identified species, brief botanical descriptions are given.

  • Distribution and Population Density of the Russian Desman (Desmana Moschata L., Talpidae, Insectivora) in the Middle Volga of Russia
    Forestry Studies | Metsanduslikud Uurimused, Vol. 71, Pages 48–68 Research paper Distribution and population density of the Russian desman (Desmana moschata L., Talpidae, Insectivora) in the Middle Volga of Russia Alexey Andreychev*, Vyacheslav Kuznetsov and Alexandr Lapshin Andreychev, A., Kuznetsov, V., Lapshin, A. 2019. Distribution and population density of the Russian desman (Desmana moschata L., Talpidae, Insectivora) in the Middle Volga of Russia. – Forestry Studies | Metsanduslikud Uurimused 71, 48–68, ISSN 1406-9954. Journal homepage: http://mi.emu.ee/forestry.studies Abstract. To date according to the registration work, the number of the Russian desman deter- mined actually is 588 individuals in Mordovia. Based on extrapolation, the total desman pop- ulation in Mordovia is about 1,400 individuals. We may assume that the most of the desman population is concentrated on floodplain lakes and reclamation canals. The highest density of the desman population in Mordovia was recorded in Krasnoslobodsky and Temnikovsky Districts (10.5 and 8.2 burrows per km, respectively). About 400 animals may live on the shore of the rivers Vad, Partsa, Yavas, Vindrey, Nuluy, and Kundybolka. The mean value of density of the desman population on the rivers was 0.9 burrows per km of the coastline, which corre- sponded to habitat quality class IV (0.5–5 burrows per km). The distribution of habitats across river basins is extremely uneven. The main part of the desman population is restricted to the Moksha basin (more than 1,350 individuals), and in the Alatyr basin (left tributary of the Sura River) just twenty individuals were recorded. Key words: Red Data Book, desman, burrow, number of individuals, river, lake, Mordovia.

Khapugin & Alexander B. Ruchin Summary: Protected areas are widely considered as tool for biodiversity conservation on a global scale. Current lack of data on biodiversity and threats in federal Russian protected areas is recognised. It especially concerns patterns of spatial plant distribution in natural ecosystems in both Russia and the whole world. Hence, research of plant diversity in protected areas is very important to obtain comprehensive knowledge on the functioning and management of plant diversity refugia. We aimed to study the most threatened component of plant diversity (i.e. Red Data Book species) in the Mordovia State Nature Reserve located in European Russia. We used personal (2010 –2018) and literary (1936 –2009) data to obtain information on habitat preferences, IUCN status, year of the first record, spatial plant distribution in protected area and taxon’s representativeness index (RI) for 47 protected vascular plant species currently known in the Mordovia State Nature Reserve. We demonstrate the higher species richness in the vicinity of some research stations and its decrease when moving away from them. These results highlight the significance of biodiversity research.

Corresponding author: A. B. Ruchin, [email protected] Abstract. A review of the distribution of the Chinese sleeper Perccottus glenii Dybowski, 1877 (Pisces, Odontobutidae) as an invasive species of fish in the territories of the reserves and national parks of the middle and lower Volga Region is presented. It occurs in 12 protected areas which is only 44.4% of the total number of protected areas. The invasion way of P. glenii in some protected areas is described, which is associated with stocking of fishery ponds. Data on habitats and the number of P. glenii in stu- died reserves and national parks are given, as well as the possible reasons for its absence in the ichthyo- fauna of other protected areas. Key Words: Chinese sleeper, Perccottus glenii, invasion, distribution, Volga river basin. Introduction. Biodiversity conservation is one of the most important tasks of the nature conservation as a whole. The federal-level Protected Areas as places of the greatest con- centration of the biodiversity and dislocation of the most significant elements of its play a special role in the biodiversity conservation of natural complexes (Brooks et al 2006; Grebennikov 2016).
