На территории Пинежского природного заповедника впервые исследован фитопланктон основного водотока ООПТ - карстовой р. Сотка. Приведены данные таксономического состава альгофлоры по основным ее отделам и данные анализа видового богатства. Установлено, что видовой состав фитопланктона представлен 56 таксономическими единицами, в том числе 46 диатомовыми, 6 зелеными, 2 эвгленовыми, 1 золотистой и 1 сине-зелёной. Для фитопланктонного сообщества р. Сотка характерны зональность и мозаичность распределения численности и биомассы, необычные для полугорных рек, к которым относится водоток. Отмечена неоднородность видового состава и комплекса доминант, наблюдаемая по всей исследованной акватории. Очевидно, это результат комплексного воздействия специфических экологических характеристик реки и в первую очередь - высокого уровня минерализации. В целом р. Сотка можно отнести к флористически обедненным олиготрофным водоемам со значительным преобладанием диатомовых водорослей, низкими количественными показателями численности и зонально-высокими значениями биомассы. Экологическое состояние водотока оценивается как хорошее, с умеренным содержанием органических веществ в воде. Phytoplankton of the main watercourse of the Pinezhsky Nature Reserve, the karst river Sotka, was studied for the first time. Taxonomic composition of the algal flora and the analysis of species richness are presented. The species composition of phytoplankton is represented by 56 taxonomic units, including 46 diatoms, 6 green, 2 euglena, 1 golden and 1 cyanobacteria. For the phytoplankton community of the river Sotka is characterized by zoning and mosaic distribution of abundance and biomass, unusual for semi-mountain rivers, to which the watercourse belongs. The heterogeneity of the species composition and complex of dominants, observed throughout the studied water area, was noted. Obviously, this is the result of the complex impact of the specific ecological characteristics of the river and, first of all, the high level of mineralization. In general, river Sotka can be attributed to floristically depleted oligotrophic water bodies with a significant predominance of diatoms, low quantitative indices of abundance and zonal high values of biomass. The ecological state of the watercourse is assessed as good, with a moderate content of organic matter in the water.

The species diversity and changes in the structural dynamics of the algal flora from the alpine lake Nesamovyte has been studied for 100 years. During the period of investigations, 234 species (245 infraspecific taxa) were revealed to cover more than 70% of the modern species composition of the studied lake. The modern biodiversity of algae is characterized by an increase in the number of widespread forms, a change from the baseline “montane” complex in comparison to the beginning of the 20th century. Nevertheless, the Nesamovyte Lake still has a unique algae composition that is typical for high-mountainous European lakes. The presence of a different complex of conventionally arctic species of algae, in particular, diatoms is discussed. Structural changes in the taxonomic composition of the algal flora of the lake as well as in the complex of the leading genera, species and their diversity are revealed. An ecological analysis of the algal species composition of the lake showed vulnerability and degradation to the ecosystem of the lake. On this basis, the issue regarding the question of protection and preservation of the algae significance and uniqueness of the flora of algae in the Nesamovyte Lake are discussed.

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.

There is analysis of the taxonomic diversity of Rotifers, Copepods, and Cladocerans from water bodies, located on the territory of clusters of the Ubsunurskaya Kotlovina State Natural Biosphere Reserve, located within the Russian part of the Ubsunur Basin, on the border with Mongolia. A total of 87 species from 53 genera, 22 families, 10 orders were recorded. Cladocerans include 40%, Copepods – 37% and Rotifers – 23%. The dependence of species diversity on the level of mineralization was established – 89% were found in fresh water bodies, in salty – 23%, in brackish – 14%. Zooplankton composition of the Lake Tore-Khol has undergone some changes in comparison with the data of the second half of the last century. The zooplankton contains species of crustaceans that are rare for the Rossian fauna – Apocyclops dengizicus, Eucyclops dumonti, Alona flossneri. Tuva is the northernmost point of A. dengizicus in Russia – its habitat, lake Amdaigyn-Khol, located at 530 parallel. The spring Bulak is polluted by mechanized water intake for technical needs, which is confirmed by the appearance of an indicator of this process – Brachionus nilsoni, which then enters the lake Shara-Nur. Location on the shore of the lake Tore-Khol camp site led to the development of Filinia longiseta, which had not previously been observed in large numbers. In general, the presence of rare species for the fauna of Russia in the water bodies of the reserve indicates the presence of favorable conditions for their development and life.

This paper is devoted to the review of the environmental and trophic characteristic features of eurytrophic wood-destroying fungi in Krasnoyarsk and its nearest suburbs in habitat conditions with various anthropogenic loads. The research covered forest stand within the green areas of the city (including islands of the Yenisei River), forest areas at the outskirts of the city and in «Stolby» state nature reserve. The research included two species of tinder fungus widely spread in the Northern hemisphere: Fomes fomentarius (L.) Fr. (confined to various hardwoods, mostly birch) and Fomitopsis pinicola (Sw.) P. Karst. (confined to trees of various species). Both species of fungi are facultative parasites. The research showed that these species of fungi use quite a restricted set of host substrates showing a pretty narrow range of trophic preferences, despite the presence of numerous species of trees suitable for them at the surveyed area. F. fomentarius uses birch, poplar and aspen as a substrate within the researched area. It is very rarely found at other wood species. The trophic range of the highly eurytrophic species F. pinicola is represented here mostly by a few coniferous species, such as pine, fir and spruce tree. This fungus is present at birch trees and aspen much more rarely. These species of tinder fungi were not found at other wood species of the surveyed area. F. fomentarius is very often found at birches in the areas with minimal anthropogenic load (in «Stolby» nature reserve) and becomes less numerous with the increasing manthropogenic load. The situation is the contrary with poplar: F. fomentarius is rarely found at poplar in the areas with low or medium anthropogenic load, but often destroys poplar wood in the areas with the increased anthropogenic load (within the green space of urban areas). Moreover, F. fomentarius is often found in parklands, rather than along the roadside lanes. F. pinicola is typical for ecosystems with low anthropogenic load and prefers coniferous wood species. It is mostly found in ecosystems of “Stolby” natural reserve, mainly on fir and pine species.

The article gives a classification of biotopes and analyzes the features of the biotopic distribution of nesting birds of the Karadag nature reserve (2874.2 hectares), located in the extreme east of the Main ridge of the Crimean Mountains and including the Karadag mountain group (2065.1 hectares) with the adjacent Black Sea water area (809.1 hectares). On the basis of previously developed schemes and taking into account our own research, the following main types of habitats were identified: 1) natural tree and shrub vegetation; 2) open grassy biotopes; 3) rocky landforms; 4) seashore (except for rocky forms); 5) anthropogenic biotopes. Seventy-nine bird species were recorded nesting in the reserve. Ornithocomplex of natural wood and shrub communities includes 52 species, including 40 in oak open woodlands, 21 in juniper open woodlands and 32 in forests. The ornithocomplex of rocks (13 species: 9 on seaside rocks and 10 on off-shore cliffs) is characterized by high specificity as 9 species nest exclusively in these biotopes. The ornithocomplex of open herbaceous habitats is depleted and sparsely specific (10 species, most of which are common with sparse woodlands). The species composition of nesting birds of the sea coast (ground cliffs in bays, beaches with coarse material) is extremely poor (2 species). Thus, the basis of the nesting avifauna of the reserve is formed by the species of tree-shrub and rocky biotopes (in total, 82,3 % of the species composition). These ornithocomplexes include 67–89 % of the species composition of the corresponding habitats in the eastern part of the Mountainous Crimea. On the other hand, the small area, peripheral location and isolation of the Karadag mountain group resulted in the absence of a number of rare species in these biotopes and the low abundance of some species common and numerous in other regions of Eastern Crimea. At least 37 species (46,8 % of nesting avifauna) use anthropogenic biotopes – forest plantations (21 species), park (18), buildings (11), freshwater reservoirs (2). Ten species listed in the Red Data Books of the Russian Federation (7) and Crimea (9) nest in the reserve. Most of them (7 species) inhabit rock and rock-coastal biotopes, including 4 species nesting on coastal cliffs of the Beregovaya ridge. The role of the reserve is significant for preservation of Phalacrocorax aristotelis (about 10 % of the Crimean population) and Falco peregrinus (about 7 %).
