Numerous species of Eunotia Ehrenb., widely distributed in the world flora, prefer acidic, dystrophic or oligotrophic freshwater habitats with low conductivity and usually occur in epiphytic or epilithic hydrotopes. In Ukraine, only 32 species and eight varieties of Eunotia were known until this study. For the first time, 9 more species have been recorded mainly from the Cheremsky Nature Reserve, located in Ukrainian Polissya. New findings include 2 species widely distributed in the world flora on most continents and 7 rare species known from several locations, among them E.genuflexa, E.jarensis and E.ruzickae, which are probably European endemics as they have not been reported from other continents. For the present time in the Cheremsky Nature Reserve, the 20 species recorded here, the highest species richness of Eunotia in Ukraine, bring the total number of Eunotia in Ukraine to 41 species, which comprises only 7% of Eunotia species in the world flora. This is indirect evidence of insufficient investigation of the wetlands in Ukraine where Eunotia usually is represented with high species richness. Several definitions are suggested to describe morphological features that are peculiar to the diatom frustule particular to the Eunotia species. The genus Eunotia possesses a mirror-symmetric, mantle-offset, brevisslit raphe system, which may or may not have terminal raphe fissures. Morphological analysis provided in this study revealed the absence of terminal raphe fissures for many species of Eunotia. Instead, the distal ends of the raphe slits finish on the outer valve surface by funnel holes, sometimes pore-like ones, connected with the helictoglossae. However, in the literature those distal ends of the raphe slits were described erroneously as terminal raphe fissures. For the first time different types of raphe system are grounded. Two species Eunotiaimplicata Nörpel-Schempp et al. in Alles et al. and Eunotiaincisa W. Smith ex Gregory were lectotypified.

Comprehensive Study

This article is devoted to a comprehensive study of the structural and semantic features of dish names and their descriptions in German in the field of restaurant discourse. The study employs cognitive discourse analysis, elements of comparative and contextological approaches, taking into account linguocultural parameters. The relevance of the comprehensive study of the names of dishes in restaurant discourse is due to an increased interest in the parameterization of lexical units in different types of institutional discourse. The scientific novelty of this work lies in the fact that for the first time, within the framework of a restaurant menu, not only the nomination of a dish is considered, but also the structural and semantic characteristics of its description are analysed. An attempt is made to analyse a connection between the nominations of dishes and their description in the restaurant menu, as well as to determine the semantic dominants of the genre under study. It is concluded that the text of the menu as a whole presents a combination of the language for special purposes and the language of advertising. In interaction with extralinguistic factors, the nominations of dishes and their descriptions not only document the culture of food in society, but also reflect the ethnocultural picture of the world. Based on the analysis of the menu texts, it is established that structurally the names of dishes are complex words or phrases, built mainly according to the attributive model. The description of dishes performs the function of verbalizing the sensations of taste and clarifying the method of preparing dishes, characterizing the quality of dishes, their ingredients, and the intensity of taste. Evaluative parameters in descriptions are expressed at the lexical, grammatical, syntactic and stylistic levels.

The fauna of the longhorn beetles of ecoregion of Kremenetski Hory and the eponymous National Park was studied very poorly. In the most recent catalogue of Cerambycidae of Western Podillya it was listed only 13 species for the ecoregion. Including other sources, to date, it was known 17 species of the longhorn beetles. In the current study we identified 59 species of the longhorn beetles, 42 of which are reported for the first time for National Park «Kremenetski Hory» and the ecoregion in general. Under our proposed prediction the Cerambycidae species richness should reach 100-120 species. We also presented result of quantitative study of the longhorn beetles within different types of ecosystems of National Park «Kremenetski Hory». We revealed that 10 species are the most abundant on the studied territory.

The paper provides the first results of a study of the qualitative and quantitative structure of the community of bottom meiofauna (meiobenthos) in shallow, hypereutrophic Lake Nero (Volga River basin, Yaroslavl region, Russia). In the samples, collected in early September 2017, 106 representatives from 16 systematic groups of aquatic organisms were found. About half of them had not been previously recorded in the lake's fauna. The species composition of Gastrotricha, Nematoda, Tardigrada, Acari, Harpacticoida, and Ostracoda was analyzed in the water body for the first time. It is established that at the end of the vegetation season, the lake's meiobenthos characterizes by relatively high species richness, diversity, and quantitative parameters. The circle of the main (dominant) community members in the studied period was outlined.

Lake Hula, the core of one of the most extensive wetland complexes in the Eastern Mediterranean, was drained in 1951–1958. However, about 350 hectares of papyrus marshes were allocated in the southwestern part of the previous lake and became the Hula Nature Reserve status, the first of two wetlands in Israel included in the Ramsar List of Wetlands of International Importance. The list of algae and cyanobacteria species of Lake Hula was compiled by us for the first time based on data from publications of 1938–1958, as well as our research in the Hula Nature Reserve, obtained within the framework of the monitoring program for 2007–2013. The list includes 225 species and intraspecies of algae and cyanobacteria belonging to eight phyla. The dynamics of the species richness of algae and cyanobacteria flora for 1938–2013 are shown. Species-bioindicators of water quality have been identified, and the change in their composition by ecological groups for a period of about a hundred years has been shown. Based on the species richness of algae communities, water quality indices were calculated with particular attention to changes in trophic status during the study period. The algae flora of Lake Hula and Hula Nature Reserve was found to be similar, but bioindication has revealed an increase in salinity and organic pollution in recent years.

Abstract: The Amazonian rainforest harbors one of the most diverse mammal faunas found anywhere in the world, although this fauna is still poorly known. Inventories are essential for the understanding of the biology and ecology of species, and provide basic data for conservation. Over 15 years of sampling in the Saracá-Taquera National Forest, we recorded 72 species of small (nonvolant), medium, and large mammals belonging to 30 families in 10 orders. These taxa included 29 species endemic to the Amazon biome, and 14 classified as threatened with extinction. Overall, the mammalian species richness recorded in the present study was equal to or greater than that recorded in other Amazonian studies, reflecting high levels of diversity on a biogeographic scale. This reinforces the importance of this national forest for the maintenance of the region's mammalian fauna. Some of the species were recorded in the region for the first time, thus extending their known geographic distribution.

During the period of March 2004 to December 2007, samples of aerial litter (dead but still attached plant parts) and ground litter were collected from study sites representing a wide range of latitudes (34° S to 50° S) and a variety of different types of habitats throughout New Zealand (including Stewart Island and the Auckland Islands). The objective was to survey the assemblages of protosteloid amoebae present in this region of the world. Twenty-nine described species of protosteloid amoebae were recorded, along with the heterolobesean acrasid, Acrasis rosea. Of the species recovered, Protostelium mycophaga was by far the most abundant and was found in more than half of all samples. Most species were found in fewer than 10% of the samples collected. Seven abundant or common species were found to display significant preferences for aerial litter or ground litter microhabitats. There was some evidence of a general pattern of a decrease in species richness and diversity with increasing latitude and precipitation and elevation.

The diversity of Brazilian vertebrates is regarded among the highest in the world. However, the biological diversity is still mostly unknown and a good part of it is seriously threatened by human activities. This study aimed to inventory the medium and large size mammals present in the Reserva Biológica de Santa Rita do Sapucaí, an Atlantic forest reserve located in Santa Rita do Sapucaí, southeastern Brazil. Sand-plots, photographic traps and searches for animal tracks on pre-existent trails in the area, were carried out once every two months between May 2006 and February 2007. The sand-plots and tracks were inspected during five consecutive days per sampling. We obtained 108 records of 15 species, mostly of carnivorans. Two confirmed species are threatened with extinction in Brazil (Callithrix aurita and Leopardus pardalis). The results suggest that the sampled reserve has high species richness and plays an important role in conservation of mammals in this landscape, including species threatened with extinction.

The oribatid mite genus Cultroribula Berlese, 1908 is represented in Mongolia with six species. Most species of Cultroribulafound in Mongolia are inhabitants of litter of various types of forests, soils of steppes and the high mountain alpine zone, butare also commonly found in lichens growing on trees or bare rock and terricolous bryophytes. In this work, two species, Cul-troribula altaica sp. nov. and Cultroribula rarisetosa sp. nov., are described as new to science based on adults collected fromlitter of cool temperate forests and lichens growing on bare rock, respectively, in western Mongolia. In addition, two knownspecies, Cultroribula berolina Weigmann, 2006 and Cultroribula vtorovi Krivolutsky, 1971 are redescribed. Cultroribula bero-lina is recorded for the first time for the fauna of Asia. Species descriptions are accompanied with detailed illustrations. Data ongeographical distribution and habitat ecology are given for all known species in the world. Issues concerning the taxonomic sta-tus of some genera of Astegistidae and species of Cultroribula are discussed. The subgenus Furcoppia (Mexicoppia) is consid-ered as a junior synonym of Cultroribula. The new combination, Cultroribula hauseri (Mahunka, 1983) for Furcoppia(Mexicoppia) hauseri Mahunka, 1983 is proposed. Furthermore, a key is provided for the identification of adults of the known species of Cultroribula in Mongolia.

The present paper focuses on the flora of synuralean algae from four northern provinces in Vietnam: Bac Kan, Hanoi, Ninh Binh, and Thanh Hoa. Fifty-five water bodies were studied, including territories within national parks Ba Be, Ba Vi, Cuc Phuong, Ben En, and Trang An Wetland—The World Cultural and Natural Heritage and Van Long Wetland Nature Reserve. Samples were obtained from natural lakes and wetlands, artificial reservoirs and ponds, and small temporary water bodies. Electron microscopy allowed for the discovery of 39 taxa, 37 of which belonged to the genus Mallomonas and two to the genus Synura. Six taxa of the genus Mallomonas and two taxa from the genus Synura were not identified to the lower rank. Five taxa are reported for the first time in Vietnam. The most diverse flora was observed in natural protected water bodies. Eutrophic and hypereutrophic water bodies, which were prevalent in the study area, had a reduced number of selected species.

This study strives to address the needs of a Gauteng provincial nature reserve in order to develop a greater understanding of the visitors’ profile to this reserve in terms of demographics and motivations for visitation. Understanding the motivations for different types of visitors is vital for reserve management to adequately satisfy the visitors’ needs. An exploratory factor analysis was used to identify visitor segment profiles based on their motivations for visiting the reserve. The factor analysis revealed six motivation factors. These segments included relaxation and escape; nostalgia and history; personal benefits; wildlife and geographical features; convenience and part of lifestyle; and participating in an event. The study, furthermore, identified, for the first time at a South African provincial nature reserve, a new motivator factor: participating in an event. The results show that segmentation by motivation is a useful research tool for identifying what motivates visitors to travel. Understanding the differences within these segments will help management offer satisfying innovative activities and services to visitors. Recommendations for management include providing opportunities for nature enthusiasts by enhancing awareness creation of the fauna and flora present in the reserve as well as providing opportunities for relaxation and escape through the introduction of recreational facilities such as wellness programmes. Improved amenities are required such as refreshments, curios retail and overnight accommodation. The reserve appeals widely to mountain bikers; thus, marketing efforts should be directed towards this group.
