The article presents the results of the authors’ long-term research (2011–2017), including the collection ofherbarium material in all regions of Khakassia, as well as accounting of materials of big Siberian herbaria (HGU, KRAS,NS, TK) and literary information. A taxonomic analysis of the family Rosaceae Juss. was performed for the first time forthe flora of Khakassia on the basis of the original synopsis, which includes 108 species from 26 genera. The taxonomicstructure of Rosaceae in Khakassia flora testifies to its relative autochthonous nature. The average number of species inthe genus is high – 4.2. This indicator is higher than the indicators for the entire flora of Khakassia – 3.24, for the floraof the northwestern part of the Altai-Sayan province – 3.5 (Alchemilla s. l.), for the flora of the Yenisei Sayans – 3.8,where autochthonous trends are noted. More than half of the species in the family (57) contain the genera Alchemilla andPotentilla, whose centers of speciation are located in mountain systems.

Located in southwestern Maranhão, the Parque Nacional da Chapada das Mesas (PNCM), with an extent of about 160,046 ha, is completely inserted in the Cerrado phytogeographic domain. The topography is characterized by a plateau formation consisting of steep hills and medium-altitude mountains with flat tops, which give the PNCM its name. We present an annotated checklist of the mosses that occur in the PNCM. Our checklist includes 26 species of pleurocarpous mosses distributed in 10 families and 22 genera and two species of cladocarpous mosses of the family Orthotrichaceae. The most species-rich families of pleurocarpous mosses were Sematophyllaceae (7 spp.), Pylaisiadelphaceae (6 spp.), and Stereophyllaceae (4 spp.). Eleven species are recorded for the first time from Maranhão and three species are recorded for the first time in the northeast region of Brazil. Taxithelium pluripunctatum (Renauld & Cardot) W.R. Buck and Trichosteleum glaziovii (Hampe) W.R. Buck, are recorded for the first time from Maranhão and the Cerrado phytogeographic domain. Our results expand the knowledge of the Brazilian bryoflora and add distribution data for a number of species in Maranhão and the northeast region.

The fauna of parasitic mites of bats from the karst caves in the region of the Volga Upland was studied in 2004-2005. Six species of bats such as Daubentons water bat, Brandts bat, whiskered bat, pond bat, northern bat and long-eared bat were examined. 18 species of arthropods were detected, among them there are gamasid mites (10 species) and harvest mites (2 species). Leptotrombidium russicum (Oud., 1902) and Myotrombicula sp. were found for the first time in Central Russia. Spinturnix acuminatus (Koch, 1836), Steatonyssus spinosus (Willmann, 1936), Steatonyssus periblepharus (Kolenati, 1858), Macronyssus flavus (Kolenati, 1856) turned out to be the main group of parasites in this study. As for the insects flies of the family Nycteribiidae and fleas of the family Ischnopsyllidae were found. The cluster analysis of ectoparasite fauna has showed that they are more or less evenly distributed among all members of mixed colonies of bats, while there is no violation of specificity in the choice of hosts. Low values of the Berger-Parker index marked a lack of competition between species, which indicates the stability of parasitic communities formed on bats in mixed colonies and in natural habitats. This fact indicates a complex relationship between the parasites in the community on the one hand, and long-term existence of the community on the other hand. This, in its turn, shows that in long-evolving communities competitive relationships between parasites are obliterated, which gives them stability. Herewith the bat colony is used as an integral whole, although some parasitic species prefer certain types of hosts.

The inventory and assessment of species diversity in the mono-generic family Begoniaceae C. A. Agardh of Bangladesh were made through long term field investigations, collections, identification, survey and examination of preserved herbarium specimens and review of relevant taxonomic and floristic literature. The family is recognized to be represented in the flora of Bangladesh by 19 species under the genus Begonia L. Of these, 11 species were known to be previously recorded from the area of Bangladesh, hence additional 8 species of the present account are being reported here for the first time as new records from Bangladesh, these are: Begonia grandis Dryand. ssp. holostylla Irmsch. , B. heracleifolia Cham. and Schltdl. Cult., B. maculata Raddi Cult. B. modestiflora Kurz, B. muliensis T. T. Yu. Cult., B. scintillans Dunn, B. surculigera Kurz and B. thomsonii A. DC. An enumeration of these 19 species is prepared, and each species is cited with detailed taxonomic data. All species of the Begonia L. are herbaceous in nature and possess potential economic values, viz. 11 (52%) medicinal, 5 (24%) ornamental, 3 (14%) beverage, 1 (5%) food and 1 (5%) poisonous. Determination of status of occurrence showed that 2 (10.53%) species are common, 5 (26.32%) cultivated, 9 (47.36%) threatened and 3 (15.79%) possibly extinct in Bangladesh. Field photographs and hand drawings of recorded taxa are provided.J. Biodivers. Conserv. Bioresour. Manag. 2018, 4(1): 35-46

This article suggests research to determine whether more valuable legal advice can be given in three areas. The emotional distress caused by prenuptial agreements to people under 30 years old who are marrying for the first time is not justified because these agreements often do not accomplish their intended goals. Regarding estate planning, business owners and their lawyers often focus primarily on tax savings without considering the long-term impact of the estate plan on the family business. Finally, the advantages to the family business of agreements for the buyout of disgruntled minority shareholders are discussed.

A floristic study including the taxonomic identity and distribution of Agavaceae was done for Querétaro, México. In Mexico, the family Agavaceae is very important for its etnobotan ical, evolutionary, floristics and taxonomic relevance. Even that Querétaro has a high environmental diversity, the knowledge of the family was limited with previous reports of 15 species. By intensive collections, six genera and 31 species were found. Out of them, two genera (Beschorneria and Prochnyanthes) and 16 species are new reports for Querétaro. Besides, two species of Agave are new for science, and the natural distribution of Agave alboma1ginata is known for the first time. Comparing the number of species of Agavaceae per unit of area from each State in México, we conclude that Querétaro is the third more diverse state.

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.
