An annotated list of 29 species from 18 genera and 10 families of Trichoptera inhabiting rivers and streams of the Mountainous Shoria is given. All species are recorded from this region for the first time. Two species, Dicosmoecus obscuripennis Banks, 1938 and Rhyacophila lata Martynov, 1918, are new for Western Siberia. Moreover, Mountainous Shoria is the westernmost locality for Rhyacophila narvae Navas, 1926, Neophylax ussuriensis (Martynov, 1914), and Stenopsyche griseipennis (McLachlan, 1866) distribution.

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.

During the geobotanical survey of the vegetation of the southern part of the Nature Park "Numto", located within the subzone of the northern taiga in the center of the West Siberian Plain, 140 species of bryophytes, including 87 species of mosses and 53 species of liverworts, of which 24 species of mosses and all liverworts are new to the territory of the Nature Park. Two species of sphagnum mosses – Sphagnum inexpectatum and S. mirum – are the most important finds for the Western Siberia. Sphagnum inexpectatum is listed for the first time for the territory of Khanty-Mansi Autonomous District. The information on ecology and phytocenotic confinement of 18 species of mosses, known earlier in the Nature Park from one point or on a few and single finds, is supplemented. An annotated list of all identified species of bryophytes is given.

Comprehensive Study

A comprehensive study of the composition of sand and silt deposits of the Yu1 horizon of the Vasyuganskaya Formation upper part of the Verkh-Tarskoye oil field has been carried out. Associations of authigenic minerals have been determined in their cement, among which the calcite is the most widespread. According to petrographic parameters, three generations of calcite have been identified for which detailed isotopicgeochemical and ultramicroscopic studies were carried out for the first time. Wide and multi directional changes in the isotopic composition of carbon and oxygen and in the chemical composition of carbonate minerals were recorded, they indicate significant variations in the conditions of diagenesis and catagenesis, primarily temperature, and different sources of CO2. Significant variations in the isotopic composition of formation waters and its relationship with the isotopic composition of carbonates have been established. Thus, a narrow interval of close δ13C values was revealed, amounting to –10.5 to –9.1 ‰ in the formation waters of group II, and from –10.7 to –9.1 ‰ in calcites of the third generation. The source of CO2 in this system should be considered a carbon dioxide, which is formed in the process of metamorphism of carbonate rocks of the Paleozoic age.

Thirteen previously-described species are reported from Belize for the first time, ten of which represent new generic records: Eupheno histrionicus Stål, 1862 (Cetherinae); Ghinallelia signoreti (Dohrn, 1860) (Emesinae); Rasahus albomaculatus (Mayr, 1865) (Peiratinae); Leogorrus interruptus Champion, 1899; Microlestria laevis Champion, 1899; Nalata quadrituberculata Champion, 1899; Nalata setulosa Stål, 1862; Pseudozelurus superbus (Champion, 1899); Zelurus spinidorsis (Gray, 1832) (all Reduviinae); Oncerotrachelus conformis Uhler, 1894; Saica fuscipes Stål, 1862 (both Saicinae); Gnathobleda litigiosa Stål, 1862; and Stenopoda wygodzinskyi Giacchi, 1969 (both Stenopodainae). Among the ten subfamilies reported, Belizean records for one subfamily, Saicinae, are reported for the first time. Accompanying the checklist are the descriptions of Castolus omega Swanson sp. nov. (Harpactorinae) and Pygolampis aptena Swanson sp. nov. (Stenopodainae).

First Time

For the first time some outcrops of the Upper Miocene Ishim Formation on the south of Tyumen Area near Pyatkovo, Masali and Bigila villages are studied by palynological method in detail. A series of mineralogical analyzes of these sediments and radiocarbon analysis of the Quaternary sediments overlying the Ishim Formation are done. Four palynocomplexes (PC) are established in the Ishim Formation: PC1 with Botryococcus; PC2 with Botryococcus, Sigmopollis; PC3 with Alnus, Polypodiaceae, Botryococcus, Sigmopollis; PC4 with Betula, Alnus, Corylus. The layers with PC1, PC2 и PC3 are traced in two outcrops near Masali and Bigila Villages. PC4 is revealed from the sands and aleuropelits of the outcrop near Pyatkovo Village, it is characterized by a significant content of diverse pollen of temperate termophylic broad-leafed taxa and by the presence of rare typical Miocene elements (Таxodiaceae, Nyssa, Tsuga). The PC3 and PC4 are compared with the complexes well known from the Neogene sediments of Western Siberia. PC5 with Betula, Herbae, Fungi is revealed from the bedded silts overlying the Ishim Formation in Masali outcrop. Previously, these sediments were attributed to the Late Miocene Pavlodar Formation. The composition and the structure of PC5 allowed making an assumption about Quaternary age of the enclosing sediments. Radiocarbon analysis of the organic substance from the silts showed, that these sediments were accumulated in the Late Pleistocene (Sartan Ice Age). For the first time the information about microphytoplankton (Botryococcus, Pediastrum, Zygnemataceae, Sigmopollis) and other nonpollen palynomorphs, contained in Ishim Formation (Upper Miocene) and in Pleistocene sediments, is given. On palynological data, some stages of development of the Late Miocene Ishim Basin and the type of vegetation surrounding this basin are considered. The depositional environment of Pleistocene sediments (Masali outcrop) is reconstructed.
