Based on a study of samples made by the author, 70 species of freshwater bivalves belonging to 6 genera and 2 families are recorded for the Taz River basin (north of Western Siberia). An annotated list of bivalves of the Taz basin is provided, with data on species’ range, their findings in Western Siberia and within the studied area. Some information about bionomics and abundance of bivalves are given. 45 species are for the first time registered in this basin. Most studied molluscan communities are characterized by low species richness; the distribution of species by their occurrence was extremely uneven. 22 species are characterized as rare. The highest species richness of bivalves was found in river channels, rivers and brooks; the lowest - in temporary habitats. The core of the fauna is constituted by species with broadest range (cosmopolitan, trans Holarctic, trans Palearctic) as well as by taxa with European Siberian type of distribution. From the taxonomic point of view, the bivalve fauna of the Taz basin is relatively separated from the faunas of other river basins of Western Siberia and is more similar to the fauna of the Lower Yenisean zoogeographic province (sensu Starobogatov [1986]).

The fauna of the rivers of the north of Western Siberia that do not belong to the Ob’ River basin is of particular interest from the point of view of zoogeography and understanding of the processes of formation of the freshwater malacofauna. Starting in the taiga zone, these rivers flow north and cannot serve as a way of interzonal dispersal of species from lower latitudes. However, information about the fresh-water malacofauna of these river basins is poorly presented in the scientific literature, some of the published species findings are doubtful or erroneous. The gastropod mollusks of the family Valvatidae of the Taz river basin (Western Siberia) are considered. The basin is located closer to the Yenisei than to the Ob’ River basin. The study was based on original authors’ material represented by both qualitative and quantitative samples. It has been found that eight species of mollusks of the genus Valvata occurs in the water reservoirs and streams of the Taz basin, an annotated list of species is presented, and a brief zoogeographic characteristic is given. Three species (Valvata helicoidea, V. sorensis and V. korotnevi) are for the first time recorded from the basin, one of them (V. korotnevi) is for the first time recorded from the Western Siberia waterbodies.

Aspidosperma Mart. is one of the most important genera from Apocynaceae Juss. occurring in Brazil. It is present in many plant formations and has species with both medicinal and economic value. From a taxonomic point of view, many of its species are difficult to identify, especially those occurring in the Amazonian region. In order to complement the information already available with regard to the taxonomy and distribution of the genus, the goal of this work was to provide a taxonomic study of the Aspidosperma species occurring in the state of Pará, northern Brazil. This study was based on the analysis of vouchers from the BHCB, HBRA, IAC, IAN, INPA, MG, R, RB and UEC herbaria, as well as scanned images of vouchers from Brazilian and foreign herbaria, and specimens collected in the field. Species identification was confirmed by analysis of protologues and types (or images). We present taxonomic descriptions, illustrations and one identification key for the 20 species of Aspidosperma found in Pará, with the Baixo Amazonas Mesoregion presenting the largest number of species (17), and the Metropolitana de Belém Mesoregion presenting the smallest number of species (3). Aspidosperma eteanum, A. oblongum, A. salgadense (endemic of Pará) and A. sandwithianum are accepted as species here. Aspidosperma cuspa is a new record for Pará. The fruits of Aspidosperma eteanum and A. salgadense, and the seeds of A. eteanum, have been described and illustrated for the first time.

Taxonomic Changes

The diversity of Eriocaulaceae in the Neotropics is primarily concentrated in the Espinhaço Range in Brazil and in the Tepuis of Venezuela. Species richness outside of these areas, however, is significant but poorly known. Based on improved taxonomic knowledge about Eriocaulaceae in the Atlantic Forest domain in Brazil, we propose nomenclatural and taxonomic changes, and provide an identification key and an annotated list of the species of the core Serra da Mantiqueira. A total of 24 species were found, one described quite recently and two still known only from the type specimens. Lectotypes for the following names are designated: Eriocaulon majusculum, Paepalanthus exiguus, P. jordanensis, P. manicatus, and Syngonanthus caulescens.

Result of an extensive moss study of earlier nearly unexplored areas of the northeastern part of the Subpolar Urals, namely Khulga River Basin is presented. An annotated list of mosses is compiled based on the identification of 1200 specimens collected in the Khulga River Basin (60.45–65.20°N, 60.42–62.20°E). The river starts at the border between the Polar and Subpolar Urals and flows down southwards along the eastern slope of the Ural Mountains to the confluence with the Severnaya Sosva River near the village Saranpaul (Berezovo District, Khanty-Mansi Autonomous Area — Yugra). The list includes 210 moss species, of which 56 species are new to the Khanty-Mansi Autonomous Area — Yugra. Five species are new to the Urals: Didymodon perobtusus, Lewinskya iwatsukii, Schistidium frisvollianum, Sphagnum mirum, Warnstorfia tundrae. Further 9 species were found in the Subpolar Urals for the first time: Dicranum bardunovii, D. laevidens, D. schljakovii, Encalypta pilifera, Flexitrichum gracile, Grimmia elatior, G. tergestina, Orthotrichum hyperboreum, Sphagnum annulatum. The data on occurrence of many moss species, which were previously known from single finds in the mountainous part of the area, is significantly expanded. Ecology, phytocenotic preference and distribution of the recorded species are discussed.

The subject of this article is the literary landscape of Western Siberia, which was represented in “Essays from life in Siberia” (1895) by Nadezhda Aleksandrovna Lukhmanova. The relevance of this research is determined by the increased importance of studying “local” texts of Russian culture, including the need for a more detailed study of the phenomenon of Siberia. The mythopoetics of landscape in N. Lukhmanova’s “Essays” is considered in the context of prose of the turn of the 19th-20th centuries (G. Uspensky, K. Nosilov). The literary context of the study of “Siberian” texts for the first time includes the stories by S. I. Kartsevsky. The geographical imagery of Western Siberia is reconstructed in the texts under consideration from the point of view of philological analysis, which allows determining the features of representation of the Place in the creative thinking of a particular writer and identifying the individual author’s view of the depicted locus. “Essays from life in Siberia” by N. Lukhmanova reflect different points of view on the landscape of the Siberian city. Geographical remoteness, climatic conditions, and the closed way of life of old believers form the image of a fortress city, “the country behind the Stone”. The reflected provincial way of life of the city is destroyed on the pages of “Essays” with the arrival of merchant children who were educated in the capital, the growth of industry, the laying of the railway. Siberia in the minds of newcomers appears “a remote, lost place”, while in the perception of Siberians it is the “native land”, “Paradise”. N. Lukhmanova’s “Essays” reflect the “double mythologem” of Western Siberia: it is “alien”, closed space and at the same time “one’s own”, “reserved”, and “secret”.

Streams are environments that are very affected by human activities such as pollution, deforestation of riparian forests and introduction of exotic species. In this context, it is important to know its biodiversity for monitoring and conservation. The present study inventoried the fish fauna of three tributary streams of the Jacarezinho River (Cinzas River basin, Paranapanema River) with different environmental characteristics: Água dos Anjos, Monjolinho and Ubá streams. Quarterly collections were performed in the period between October 2012 and July 2013 at the headwaters, in the middle and at the mouth of each stream, using electrofishing. We analyzed the parameters of species richness, total abundance, relative abundance, capture constancy, rarefaction curves of Coleman, and richness estimators ACE and ICE. We captured a total of 7102 individuals, distributed in six orders, 12 families and 33 species. The most abundant order was Characiformes (76.15 %), while the most abundant species were: Bryconamericus iheringii (39.5 %), Astyanax bockmanni (19.36 %), and Geophagus brasiliensis (7.52 %). The highest species richness was found in Água dos Anjos stream (26), followed by Monjolinho stream (25), and the Ubá stream (15). We recorded the occurrence of four non-native species (Bryconamericus exodon, Gymnotus inaequilabiatus, Poecilia reticulata and Oreochromis niloticus), which represent a risk to the biodiversity of the studied streams. The Ubá stream was considered the most conserved, but the presence of P. reticulata shows that it has also suffered from anthropic impacts. This non-native species is constantly associated to degraded environments, mainly when it occurs in high abundance. Our results suggest that the fish assemblages studied present different structures, probably due to the interaction among historical, abiotic, biotic, and anthropic factors. This study has been carried out for the first time in the Cinzas River basin and can help provide theoretical input for the elaboration of monitoring and conservation plans.
