Abstract. Andreychev A. 2021. Short Communication: Proportion faunal assemblages of carnivorous mammals in geoecological districts of Mordovia, Russia. Biodiversitas 22: 4625-4632. In the forest-steppe area, carnivorous mammals are represented by species of different faunistic assemblages. This circumstance makes the study region a priority since the species of which faunistic assemblages prevail is of interest. Fifteen carnivorous species have been identified in the territory of Mordovia. Among them, the family Mustelidae predominates in terms of the number of species. The species are found in all geoecological districts, but their distribution is uneven. The most notable species in the region are located in coniferous and broad-leaved forests (40%) and species widely distributed in several natural areas (40%). 13% of the total number of noted species belong to the taiga fauna types. The steppe type of fauna is represented by only 7% of the total number of recorded species. For each geoecological region, the fauna features are given, and a list of rare and exciting species is given. The forest-steppe zone to which Mordovia belongs is compared by the fauna of carnivorous mammals with other regions from three typical faunal assemblages.

Floristic Structure

Ecological approach to the study of flora implies an integral flora unit called elementary flora (EF), which is usually regarded as the elementary unit of floristic division. Identification of the minimum-range of EF is prerequisite for the research of flora of any territory. The aim of this research is to identify the number of EF in the research area (floral patterns) by comparing the values of certain parameters of the family range of flora in four minimum-ranges. The basin of the river Sok is the research area. Its landscape zoning varies in different literature sources. Florae of the four minimum-range habitats are formed on territorial basis with reference to the existing floristic descriptions. The following parameters of the family range of flora in four minimum-ranges were used: establishment of the order of the first triad of families depending on number of species in a sample, percentage of monotypic families and percentage of species in the top ten families. The considered values of florae parameters in the sample areas corresponding to the minimum-range habitats show a certain degree of similarity. The largest differences were observed in the study of the formation of top three leading families, depending on the number of species. This indicator reflects the peculiarities of individual sample areas due to the variety of intra-landscape. The authors reach a conclusion concerning the conditional affiliation of the researched territory to one EF. The conclusion is based on the analyzed parameters of the family range of flora of all minimum-ranges as well as their floristic descriptions

We publish the results of a three-stage study of the floristic heterogeneity of the Melekess-Stavropol physiographic region located on the territory of the Samara and Ulyanovsk Regions. The area belongs to the forest-steppe zone of the Trans Volga Lowland and occupies the area of 7,7 thousand km. Based on the analysis of family spectra, originality of the flora of the region we show the comparison of Soksky and Irgiz physiographic regions of the Samara Trans Volga. At the first stage of the research we consider the internal heterogeneity of the region, changes in the species composition of the flora along a two-sided latitudinal gradient. For this, the course of the curve, reflecting the accumulation of the number of species with an increase in area, has been studied. The accumulation curves of the number of species aligned in both directions showed three stages of an increase in the number of species, indicating the species heterogeneity of the area. The study of the position of the leading families, depending on the size and geographical position of the floristic sample, shows the heterogeneity of the studied Melekess-Stavropol region by the flora type, which is determined by the third term of the first triple of the family spectrum. At the second stage, four floral groups (floristic samples) are analyzed, which are geographically isolated at the first step. A comparison is made of the isolated groupings at the head of the family spectra using the fraction of the family in the flora and the number of species in the family. The third stage includes a comparison of the selected floral groups of the Melekess-Stavropol physio-geographical region according to the Preston index. Taking into account the existing numerical threshold of 0,27, above which the samples should be considered as different floras, it is possible to speak of the presence of four different floras on the territory of the studied area.

This research presents three new species of carnivorous sponges from the family Cladorhizidae from the Great Australian Bight, South Australia. This research also shows a clear separation within the species currently known as Cladorhiza into those with an arbuscular or tree-like morphology from the Atlantic, to those of differing morphologies and propose three new genera, i.e. Bathytentacular gen. nov., Abyssosdiskos gen. nov. and Nullarbora gen. nov. and the resurrection of an old genus Axoniderma. nov. The three new species described in this paper are Nullarbora heptaxia sp. nov., Abyssocladia oxyasters sp. nov. and Lycopodina hystrix sp. nov. A new species in the family Guitarridae, Guitarra davidconryi sp. nov., a family closely related to the carnivorous sponges is also described in this paper. These new species are the first recorded carnivorous species from South Australia and increase the number of species recorded from around Australia to 25.

Abstract. Andrechev A. 2020. Short Communication: Proportion faunal assemblage of rodents in geoecological districts of Mordovia, Russia. Biodiversitas 21: 3961-3968. In one natural area, animals may have different distribution. In some areas they inhabit, and in other areas, they do not inhabit. Scientists have been working on this issue for a long time. In this study reports that the species composition and distribution of species varies depending on geoecological districts. Twenty-eight rodent species have been recorded in the territory of Mordovia. The largest number of species in the region belongs to those living in coniferous and broad-leaved forests (42.9%). In the second place in terms of representation are species widely distributed in several natural areas (28.5%). They are slightly inferior to the types of steppe fauna (25%). The taiga type of fauna is represented by only 3.6% of the total number of registered species. For each geoecological district, the features of the rodent fauna are given and rare species are identified. The forest-steppe region of Mordovia is compared in rodent fauna with other regions of Russia with different typical faunal assemblages.

Information about spring ascomycetous fungi on the territory of the nature tract "Kholodnyi Yar" is presented. As the result of the study 33 species of the ascomycetous fungi were identified, 19 of which are actually spring species and 14 – found in the spring. 15 species are registered for the nature tract "Kholodnyi Yar" for the first time. The largest number of species is represented by the family Morchellaceae (5 species), as well as by the families Pezizazeae (4 species) and Sclerotiniaceae (4 species). The ecological-trophic structure is dominated by species with a saprotrophic feeding strategy, which belong to xylotrophs, humus saprotrophs and herbophilic fungi. The group of xylotrophs was the predominant group of saprotrophic fungi in terms of the number of species (10 species). Humus saprotrophs numbered 9 species of the order Pezizales. In addition, representatives of the group of herbophilic (6 species), which use last year's remnants of herbaceous plants as a substrate, were quite common. Dumontinia tuberosa was the most common species among biotrophic species which parasitizes on the rhizomes of plants of the genus Anemone and forms fruiting bodies at the same time as the flowering period of the host plant. Symbiotrophs were represented by 3 species that are also capable of the saprotrophic feeding strategy inherent to humus saprophytes. A new location for Gyromitra slonevskii, Morchella crassipes and M. steppicola – species which were listed in the third edition of the Red Book of Ukraine – has been registered. Species included in the local red lists were also identified, namely Gyromitra gigas and Verpa bohemica (Kyiv region), Helvella acetabulum (Kherson region). The finding of Phylloscypha phyllogena is the second in Ukraine and the first on the territory of the Right-Bank Forest-Steppe.

We conducted research on the determination of the daily activity of blood-sucking mosquitoes of the family Culicidae in 2005–2015 in the south of Tyumen region in three climatic zones (subzones): the subzone of the southern taiga (Nizhnetavdinsky district), the subzone of aspen-birch forests (Tyumen and Yalutorovsky districts) and in the forest-steppe zone (Isetsky district). In each of the three subzones, counts were conducted twice for the summer season – in June and July. A high number of blood-sucking mosquitoes in the south of the Tyumen region have 24-hour activity. The maximum number in all natural and climatic zones of the region is observed at 23 hours. The daily rhythm of activity of certain species of mosquitoes depends on their abundance in the summer season and on their ecological characteristics. The optimal meteorological conditions under which an active flight of mosquitoes are observed: air temperature 12.6–26.0 °C, relative humidity of air – 54–100% and illuminance – 0–8600 lux. In studying the circadian rhythm, 29 mosquito species of the family Culicidae, belonging to 6 genera: Anopheles, Culiseta, Coquillettidia, Aedes, Ochlerotatus and Culex, were recorded. In the subzone of the southern taiga, we recorded a flight of 25 species, in the subzone of small-leaved aspen-birch forests – 20, and in the forest-steppe zone – 24. The peak of species diversity in all three subzones coincided with the maximum number. All registered species in terms of temperature preferences (thermophilicity) can be conditionally divided into two groups. The first group (10 species) are species that actively attack at a temperature 10–20 °C. The second group (19 species) are species that actively attack at an air temperature 10–30 °C.

The article presents the results of the field studies of small mammals carried out from 1997 till 2017 on three specially protected natural areas of the Ishim District of the Tyumen Region (on the example of subzone of the northern forest-steppe). The method of synecology helped to analyze both the species and structural diversity and integral indices of the state of communities. The method of epigenetics aimed to show the stability of development in the populations of dominant species (on the example of Myodes rutilus and Sorex araneus ). The article shows that the level of species diversity and stability of small mammalian communities is directly proportional to the area of specially protected natural areas and reversely proportional to the level of anthropogenic load on the habitat. High anthropogenic load is the reason of neutrals and anthropophiles disappearing from communities of small mammals. The index of dominance of Apodemus agrarius increases as well as the exoanthropic species. The author establishes that the information structure of all studied communities is that of poorly disturbed habitats of the forest-steppe zone of Western Siberia. The information structure of the small mammals community of the most protected areas (1108 hectares), experiencing minimal anthropogenic impact is consistently reproduced in the number of years. The analysis of small mammals community showed a low resource potential of a forest park with an area of 14,5 hectares, located in the center of the city. At the same time the integral indices of the fluctuating asymmetry of the nonmetric features of the skull in the investigated populations of M. rutilus and S. araneus indicate the stability of epigenetic processes and the good state of the land and air environment.
