Abstract The article presents the information about the current state of the larch forests of the “Bastak”. State Nature Reserve The area, ecological and cenotic conditions of growth are determined, the classification of the studied plant communities is presented, a brief description of the forest structure is given. The current state of the larch forests of the “Bastak” State Nature Reserve can be assessed as fairly stable. Currently, larch forests occupy within 25 % of the forested area. The most widespread area is occupied by lowland larch forests (94 %). Mountain larch forests are derived plant communities formed after forest cutting in fir-spruce forests.

Ruchin A, Mikhailenko AP. 2018. Fauna of mantids and orthopterans (Insecta: Mantodea, Orthoptera) of the Mordovia StateNature Reserve, Russia. Biodiversitas 19: 1194-1206. The data on the distribution and habitat confinement of one Mantodea species and44 Orthoptera species in the Mordovia State Nature Reserve are given. Of these, one species of Orthoptera (Calliptamus italicus) isrecorded for the first time for the Mordovia State Nature Reserve, four species (Mantis religiosa, Phaneroptera falcata, Conocephalusfuscus, Tettigonia caudata) are recently penetrated, one species (Conocephalus fuscus) is reported in the Republic of Mordovia for thefirst time. In the fauna of mantids and orthopterans of the Mordovia Reserve, three ecological groups were identified: polytopic, notconfined to certain biotopes (14 species), hygrophilous representatives of intrazonal habitats (5 species) and xerophiles. Among thelatter, there are species of extrazonal habitats (13 species) and confined to dry pine forests (7 species). The steppe group was notrepresented. For the three key habitats with the largest number of identified species, brief botanical descriptions are given. Factorsinfluencing the species composition and current state of fauna of mantises and orthopterans of the Mordovia Reserve are discussed, andmeasures are proposed for the conservation of vulnerable species.

The Pinega State Nature Reserve is located in the European part of Russia, Arkhangelsk Region, in northern taiga subzone. The geobotanical studies were carried out on the territory of the reserve in 2007–2014. The classification of plant communities and the geobotanical map of the reserve were made. Ecologic-phytocoenotic classification (the Russian “dominant-determinant” approach) was conducted based on 618 relevés. The relevés were grouping into classes of associations on the basis of dominant bioecological groups, and within the classes of associations - into groups of associations by the prevailing ecologic-coenotic groups of plants. Associations were distinguished on the basis of phytocoenotic significance of species (species with the highest occurrence and abundance) within the groups of associations. The significance of syntaxa was verified by the method of discriminant analysis. 35 groups of associations and 71 associations were revealed in total. The geobotanical map was compiled using Landsat 8 satellite images for 2013 and 2014. 26 indices reflecting the productivity, saturation of the vegetation moisture and soil properties were calculated for each Landsat image. The morphometric characteristics of the relief were used as well. The obtained spatial database was classified by the method of step-by-step discriminant analysis (SDA) with using training sample. The training sample was created on the basis of field descriptions and forestry data. The verification of the map is based on the significance of the discriminant axes and the quality table for discriminant analysis. The article presents the principle stages of mapping using SDA. The vegetation map shows the different vegetation types over the territory of the Reserve.

Data about flora and vegetation of forest ecosystems of the Zagatala State Reserve located in Azerbaijan have been shown in the paper. The distribution of about 200 plants in the territory was revealed as a result of research. Vegetation is classified into 4 formation classes, 12 formations, 18 associations related to 2 types of vegetation. An analysis of 43 rare species was made, of which 2 species were Atropa caucasica Kreyer., and Rhododendron caucasicum L. are recommended for inclusion in the next edition of the Red List of endangered plants of Azerbaijan.
