As material for this work the gatherings of the author executed in 2016 year. On 43 species of plants 85 samples in which 249 copies of phytoseiid mites are revealed are taken. For the statistical analysis used an occurrence index (P1, %) and an index of domination of Paliya-Kovnatski (Di). Species structure of predatory phytoseiid mites (Parasitiformes: Phytoseiidae) in plant associations of state reserve "Elanetskyi step" (Mykolaiv region, Ukraine) were studied at the first time. 21 species of 7 genera of the family are detected (A. andersoni, A. herbarius, A. maior, N. marginatus, N. reductus, N. tauricus, E. finlandicus, D. echinus, T. tiliarum, P. intermixtus, P. soleiger, A. caudiglans, A. rapida, A. pirianykae, A. recki, A. verrucosa, A. spectata, T. cotoneastri, T. laurae, T. tiliae). Frequency of occurrence and fidelity to different types of plant communities for each species of mites were determined. Amlydromella (s. str.) recki, the most common species, was with occurrence index 35.3%. The species Amblydromella (s. str.) rapida, Amblydromella (Litoseia) spectata, and Paraseiulus intermixtus were the rare species (one specimen of each species was presented at collections). Amblydromella (s. str.) recki was the dominant in the complex of plant-feeding predatory mites. Three species, A. pirianykae, A. andersoni and E. finlandicus, were the subdominants. Typhlodromus cotoneastri was the subdominant of the first order. The remaining 16 species were the secondary members of the complex.

This article deals with the results of study of species content and basic peculiarities of beaked mites-Phytoseiidae in plant associations of one of the regional centers of Ukraine. The species composition and distribution of mites-Phytoseiidae (Parasitiformes, Phytoseiidae) in plantations of Brovary town of Kyiv region were determined. Fourteen species of 8 genera of phytoseiid mites were found. Index of their existing and relative biotope connection of each registered species to vegetation types and plant species were computed. The study was conducted according to the results of material treatment on the territory of the mentioned city from 25 species of plants (16 species of hardy-shrub and 9 of herbaceous vegetations). The studies of distribution of plant-living mites-Phytoseiidae were conducted separately for hardy-shrub and herbaceous plants). The collection of faunistic material was executed during the vegetation of periods of 2011 and 2013. Within the city the collection of the material was conducted with hardy-shrub plants and herbaceous type of vegetation along the streets, in parks and squares of Brovary city of Kyiv region, district center, one of the satellite-cities of Kiev, the capital of Ukraine. The study of species complexes characteristics of mites was conducted with usage of data calculated on the basis of frequency index (Is), degree of relative habitat confinedness (F) (Pesenko, 1982) and domination index Paliy-Kovnatski (Di) (Shitikov, 2003). Only on one species of plant (F=1) 6 species of mites-Phytoseiidae were found – T.сotoneastri on blue spruce, T. laurae – on common spruce, T. aceri – on ash-leaved maple, P. incognitus – on dog-rose, P. soleiger – on mulberry-tree, A. caudiglans – on sea-buckthorn. These species can be related to stenoecic. The mentioned species are stenotopic only in relation to the sample of plants from the plant associations of Brovary, as in other regions these species of mites can populate the other species of plants. The rest 8 species, being registered on two or more types of plants, are related to euryoecic. Among them there is a group of 6 species with “positive tendencies to population of plants”, owning the indicators of habitat confinedness 0<F<1: A. andersoni (0,92–0,96), A. rademacheri (0,85–0,96), N. herbarius (0,92–0,96), T. tiliarum (0,66–0,77), A. pirianykae (0,73–0,99), A. clavata (0,82–0,98). The rest species, E. finlandicus и K. aberrans, have the expanded range of indicators in relation to habitat confinedness (-0,71<F<0,55 и -0,16<F<0,88), that specifies on their ability to populate the big quality of species. E. finlandicus has the negative indicator of relative habitat confinedness in relation to the plants of herbaceous morphotype that serves confirmation of the ecological peculiarity of the species detected earlier. The data of relative habitat confinedness of mites to certain species of plants shows availability of stenoecic (T.сotoneastri, T. laurae, T. aceri, P. incognitus, P. soleiger, A. caudiglans) and euryoecic species (A. andersoni, A. rademacheri, N. herbarius, E. finlandicus, K. aberrans, T. tiliarum, A. pirianykae, A. clavata).

The rediscovery of the supposedly lost type allows a revision of <i>Alpinites</i> Bogoslovskiy, 1971, the most advanced genus of the Posttornoceratidae. The type-species, Alp. <i>kayseri</i> Schindewolf, 1923, is so far only known from the Carnic Alps. <i>Alp. schultzei</i> n. sp. from the eastern Anti-Atlas of Morocco is closely related to <i>Alp. kajraktensis</i> n. sp. (= <i>Alp. kayseri</i> in Bogoslovskiy 1971) from Kazakhstan. A second new and more common species of southern Morocco, <i>Alp. zigzag</i> n. sp., is also known from the Holy Cross Mountains (Poland). <br><br> The taxonomy and phylogeny of other Posttornoceratidae are discussed. The holotype of <i>Exotornoceras nehdense</i> (Lange, 1929) was recovered and is re-illustrated; it is conspecific with <i>Exot. superstes</i> (Wedekind, 1908). The genus and species is also here first recorded from Morocco. <i>Post. weyeri</i> Korn, 1999 is a subjective synonym of <i>Post. posthumum</i> (Wedekind, 1918) in which strongly biconvex growth lines, as typical for the family, are observed for the first time. <i>Goniatites lenticularis</i> Richter, 1848 is a nomen dubium within <i>Discoclymenia, Clymenia polytrichus</i> in Richter (1948) is a <i>Falcitornoceras</i>. It seems possible to distinguish an extreme thin and trochoid <i>Disco. haueri</i> (Münster, 1840) from the tegoid <i>Disco. cucullata</i> (v. Buch, 1839). <br><br> Various taxa are excluded from the Posttornoceratidae. <i>Posttornoceras sapiens</i> Korn, 1999 forms the type-species of <i>Maiderocera</i> n. gen., <i>Discoclymenia</i> n. sp. of Müller (1956) is assigned to <i>Maid. muelleri</i> n. sp. <i>Disco. cornwallensis</i> is the type-species of <i>Selwoodites</i> n.gen (Sporadoceratidae) which also occurs in the Rhenish Massive. <br><br> Durch Auffinden des verschollen geglaubten Typus-Exemplares wird eine Revision der Gattung <i>Alpinites</i> Bogoslovskiy, 1971, der höchst entwickelten Gattung der Posttornoceratidae, möglich. Die Typus-Art, <i>Alp. kayseri</i> Schindewolf, 1923, kommt gesichert bisher nur in den Karnischen Alpen vor. <i>Alp. schultzei</i> n. sp. aus dem östlichen Anti-Atlas (Marokko) ist nah mit <i>Alp. kajraktensis</i> n. sp. aus Kazakhstan (= <i>Alp. kayseri</i> in Bogoslovskiy 1971) verwandt. Eine zweite, aber häufigere neue Art Süd-Marokkos, <i>Alp. zigzag</i> n. sp., wird auch im Heiligkreuzgebirge (Polen) nachgewiesen. <br><br> Die Taxonomie und Phylogenie anderer Vertreter der Posttornoceratidae werden diskutiert. Der verschollen geglaubte Holotypus von <i>Exotornoceras nehdense</i> (Lange, 1929) wird neu abgebildet und ist conspezifisch mit <i>Exot. superstes</i> (Wedekind, 1908). Die Gattung und Art wird erstmals auch in Marokko nachgewiesen. <i>Post. weyeri</i> Korn, 1999 ist ein subjektives Synonym von <i>Post. posthumum</i> (Wedekind, 1918) bei dem erstmals die Familien-typischen, stark biconvexen Anwachsstreifen beobachtet wurden. <i>Goniatites lenticularis</i> Richter, 1848 ist ein nomen dubium innerhalb von <i>Discoclymenia, Clymenia polytrichus</i> in Richter (1848) ein <i>Falcitornoceras</i>.

New data on the species composition and distribution of phytoseiid mites (Parasitiformes, Phytoseiidae) in plant associations of the National Nature Park “Ichnyansky” were obtained. Twenty species from 9 genera of the family Phytoseiidae are recorded: Amblyseius andersoni, Amblyseius herbarius, Amblyseius obtusus, Amblyseius rademacheri, Neoseiulus danilevskyi, Neoseiulus reductus, Neoseiulus zwoelferi, Euseius finlandicus, Kampimodromus aberrans, Kampimodromu corylosus, Dubininellus echinus, Dubininellus juvenis, Typhloctonus tiliarum, Amlydromella halinae, Amlydromella pirianykae, Amlydromella rhenana, Amlydromella clavata, Amlydromella verrucosa, Typhlodromus laurae, Galendromus longipilus. The calculation of the occurrence index (P1, %) of the identified species of phytoseiid showed that its maximum value is observed in E. finlandicus. This species is also the most numerous in the total number of collected specimens in the sample. Kampimodromus aberrans, D. juvenis, G. longipilus, K. corylosus, N. danilevskyi, N. zwoelferi and T. tiliarum should be considered as the most rarely encountered species with index of occurrence of 1.3%. The remaining species have intermediate values of this index. The analysis of literature data on the occurrence of phytoseiid species with the highest value of the index of occurrence (E. finlandicus, A. pirianykae and A. andersoni) in the plant associations of adjacent zones (Polesie and Steppe Zone) allowed us to reveal some regularities. In Polesie, E. finlandicus (Kolodochka, 2011) is the most common species. In the Steppe zone, E. finlandicus also has a high index of occurrence and is the third most common species of predatory phytoseiid mites. Such a high occurrence of this species is caused by a wide range of its potential victims. Euseius finlandicus is an euribiont, however more adapted to shrub vegetation. The decrease in the occurrence index of this species from Polesie to the Steppe Zone is explained by changes in the moisture content of biocenoses, as well as due to the gradual replacement of tree-shrub vegetation of grass. Amlydromella pirianykae and Amblyseius andersoni are found mainly on herbs. The detection of these species on trees and shrubs should be considered as incidental finds. The characteristic biocenoses for these species are the wet bayrachnye forests, floodplains of rivers, meadows. When choosing a biocenosis for habitat, humidity plays a key role. The analysis of the phytoseiid mites species complex in the plant associations of the Ichnyansky National Natural Park showed the presence of one dominant species, one subdominant, five types of first order subdominant and 13 minor community members in the community.

Abstract Moss mites were investigated at the edges of 4 bodies of water located in bogs: 2 lakes in Brodnica Lakeland (O and S) and 2 pools in Orawa-Nowy-Targ Basin (K and LP). The lakes differed from the pools in most of the analysed physicochemical parameters of water and in plant associations growing at their edges. Consequently, the species richness of Oribatida and their species composition differed between lakes and pools, but the total abundance of mites was similar. Abundance of most species was low, and only 13 had dominance indices (D) exceeding 1%. The acarofauna of both lakes was similar, as most abundant in them was Limnozetes foveolatus (D > 80%), and relatively abundant were Hydrozetes longisetosus, Limnozetes ciliatus, Punctoribates sellnicki, and Trhypochthonius nigricans. These species were absent or rare at the edges of pools K and LP. In the pools, differences in species structure of Oribatida were observed. At pool K, Trimalaconothrus maior was most abundant, accompanied by Hydrozetes octosetosus, H. lacustris, and Limnozetes foveolatus. At pool LP, Trimalaconothrus foveolatus was most abundant, which tolerates a wider range of humidity than T. maior; relatively abundant were also T. maior, Hydrozetes lacustris, and several species that were not found in the other bodies of water, including a generalist like Oppiella nova. In this study, Liochthonius furcillatus and Cultroribula berolina were recorded for the first time from Poland.

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.

For the first time, perennial materials on the Orchidacaeae Juss. family of Chechnya are summarizedб consisting of 15 families and 29 species. The largest genus in the family – Orchis L. is represented by 8 species. The article presents information that all members of the family are protected plants listed in the Red Book of Chechnya, Ingushetia, Dagestan, and the Stavropol Territory. Some species are not included in the list of plants to be protected, including those species that have underground tuberoids and can serve as a source of salep (for instance, Platanthera bifolia, P. chlorantha, Herminium monorchis, Traunsteinera sphaerica, Dactylorhisa incarnata, D. salina, D. urvilleana). In this connection, data on the resources of family members and the potential possibilities of their use as a medicinal raw material are of interest. We have carried out resource studies of the most common species of Orchis tridentata Scop, within the North Caucasus. The obtained data allow us to expand our understanding of the species role of Orchidaceae Juss family.

This paper for the first time investigates a family of line-symmetric Bricard linkages by means of two generated toroids and reveals their intersection that leads to a set of special Bricard linkages with various branches of reconfiguration. The discovery is made in the concentric toroid–toroid intersection. By manipulating the construction parameters of the toroids, all possible bifurcation points are explored. This leads to the common bi-tangent planes that present singularities in the intersection set. The study reveals the presence of Villarceau and secondary circles in the toroid–toroid intersection. Therefore, a way to reconfigure the Bricard linkage to a pair of different types of Bennett linkage is uncovered. Further, a linkage with two Bricard and two Bennett motion branches is explored. In addition, the paper reveals the Altmann linkage as a member of the family of special line-symmetric Bricard linkage studied in this paper. The method is applied to the plane-symmetric case in the following paper published together with this paper.

Coniferous trees and shrubs growing in natural stands are important reservoirs of naturally-occurring predators belonging to the family Phytoseiidae (Mesostigmata: Phytoseioidea). The fauna of these mites on eight native coniferous species in Poland was surveyed and an exploratory statistical investigation was carried out into mite-conifer associations. The conifers were growing in forests, national parks and nature reserves throughout Poland. A total of 2,540 specimens of phytoseiids belonging to nine species was identified. Four species were new for the Polish fauna, i.e., Typhlodromus (Anthoseius) inopinatus (Wainstein), T. (A.) caucasicus (Abbasova), T. (A.) singularis Chant and Neoseiulus gracilentus (Hirschmann). Among the studied coniferous taxa, Picea abies (L.) H. Karst supported the greatest numbers of both species and individual mites. The highest biodiversity indexes for the phytoseiids were obtained for Taxus baccata L. and Juniperus communis L. Among the phytoseiid species found, T. (T.) tiliae Oudemans occurred on all eight host species surveyed. Typhlodromus (A.) bakeri (Garman) and T. (T.) tiliae were the most dominant species and occurred on conifers with high constancy. Amblyseius andersoni (Chant) co-dominated with them on J. communis and P. abies. New to the knowledge of Phytoseiidae-host plant records were T. (A.) singularis on P. abies, T. (T.) tiliae on Pinus mugo Turra, Pi. cembra L., J. communis and T. baccata, N. gracilentus on J. communis and Pi. mugo, and T. (A.) inopinatus on Abies alba Mill., Larix decidua Mill. and P. abies. Additionally, for Poland, new Phytoseiidae-host plant associations were T. (A.) inopinatus on Pinus sylvestris L., T. (A.) bakeri on J. communis and T. baccata, T. (A.) caucasicus on A. alba, T. baccata and P. abies, and T. (A.) singularis on L. decidua.
