The paper presents information regarding specific aspects of reproduction and nutrition of two poorly studied lizard species of genus Takydromus ( Takydromus wolteri and Takydromus amurensis ) in the north-eastern part of their habitat (Primorskiy Krai, Far East, Russia). The material given in the publication was collected both in natural and laboratory conditions. Data related to quantity as well as size of eggs and juveniles (right after their birth) are presented. The joint clutch of several female of T. amurensis was found for the first time and contained 30 eggs. For the first time the incubation period has been reported for these species that inhabit Russian territory ( T. amurensis - 44-56 days, T. wolteri - 42-44). Date of escape from eggs has been revealed for T. wolteri to be earlier than given in literature and occur on second decade of August. Cline dependence of morphometric and reproductive parameters have been dealt. Both species have been shown to prefer the following invertebrates as meal in lab conditions - Aranei, Geophilomorpha, Lithobiomorpha, Tenebrionidae (larve), Muscidae, Ectobiidae и Gryllidae. New information regarding nutritional behavior is provided for T. wolteri and T. amurensis in terrarium conditions. Both species use various traits to kill and to eat the catch based on the group to which the invertebrate is related. It has been shown empirically that juveniles of T. amurensis can eat meal right in 2-3 hours after their escape from the eggs.

Results of caddisfly faunal investigations in the North Russian Far East (NRFE) are summarized based on literature and the author’s data. Up to now, 122 species from 50 genera of 17 families of caddisflies have been found within the territory under study. A general list of caddisflies and their data records in 11 collecting (distributional) areas are presented. New records for 6 species in NRFE are given and Rhyacophila mirabilis (Levanidova & Schmid 1993) is recorded for the first time from continental Asia. Former distributional data for 40 species are refined. The taxonomic diversity and zoogeographical composition of the fauna are analyzed. It is noted that family Limnephilidae predominates in the northern areas.

Hydromacrophyte flora of 22 water bodies in the Kurgan Region was studied in 2017. The aquatic study was conducted within the 6 administrative districts of the Kurgan Region: Chastoozersky (4), Petrovsky (2) Makushinski (7), Lebyazhyevsky (4), Vargashinsky (2), and Mokrousovsky (3). The area of the research was between 55 09 minutes of the North latitude and 5548 of the North latitude, from West to East - between 6553 of the East latitude and 69 19 minutes of the East latitude. During the research we selected and recorded samples of macroalgae and collected herbarium of higher hydromacrophytes. The paper contains data on species composition and frequency of hydromacrophytes occurrence; new location of Ruppia maritima L. that is considered to be rare in the Kurgan Region was found. Its the first time the specific structure of mаcroscopic algae has been given for the territory of research. It is noted that the species of Chara contraria A. Br., is a rare one, and here it is located on the Northern border of its distribution, therefore it needs protection. Most of the identified species of hydromacrophytes are common in the West Siberian plain (Northern Kazakhstan, Tyumen Region). The paper also contains information about the location of invasive species Elodea canadensis Michx. The obtained materials can serve as a basis for further hydrobotanical study of water reservoirs in the Kurgan Region.

Abstract The present article reports Dicranosepsis javanica (de Meijere 1904) (Diptera: Sepsidae) from Meghalaya and makes a note of its Oriental distribution range. The specimens were sampled in January 2014 by sweep net in the village of Schnongrim, Jaintia Hills, Meghalaya, situated in the north-eastern part of India. A short morphological description is provided for the male specimen, while the female taxonomic characters are presented for the first time. The taxonomic identification of species was confirmed by DNA Barcoding.

Abstract Origins of the Neolithic in the north-eastern part of Central Europe were associated with migrations of groups of the Linear Pottery culture after the mid-sixth millennium BC, as in other parts of Central Europe. During these migrations, a careful selection of settlement regions took place, in terms of the ecological conditions most favourable for agriculture. The enclave-like pattern of the Neolithic settlement persisted into the fifth millennium BC when these enclaves were inhabited by post-Linear groups. The remaining areas, inhabited by hunter-gatherers, were not subject to direct Neolithisation. However, there are some indications of contact between farmers and hunter-gatherers. This situation changed from c. 4000 BC onwards because of the formation and spectacular territorial expansion of the Funnel Beaker culture (TRB). This archaeological unit for the first time covered in a relatively compact way the territory under consideration. The human substratum of this process consisted of both hunter-gatherers and farmers. Consequently, one can discourse about Neolithisation as such only in the former case. Not all Late Mesolithic hunter-gatherers accepted TRB patterns. Those communities still successfully carried on traditional lifestyle, gradually supplementing it with pottery (para-Neolithic). Their Neolithisation ended perhaps only in the first half of the second millennium BC.

On June 7, 2018, a sub-mesoscale anticyclonic eddy induced by the wind (north-east) was registered on the shelf in the area of the city of Gelendzhik. With the help of field multidisciplinary expedition ship surveys, it was shown that this eddy exists in the layer above the seasonal thermocline. At the periphery of the eddy weak variability of hydrochemical parameters and quantitative indicators of phytoplankton were recorded. The result of the formation of such eddy structure was a shift in the structure of phytoplankton – the annual observed coccolithophores bloom was not registered.

NOTE: This article was published in a former series of GEUS Bulletin. Please use the original series name when citing this article, for example: Chadwick, B., Garde, A. A., Grocott, J., McCaffrey, K. J., & Hamilton, M. A. (2000). Ketilidian structure and the rapakivi suite between Lindenow Fjord and Kap Farvel, South-East Greenland. Geology of Greenland Survey Bulletin, 186, 50-59. https://doi.org/10.34194/ggub.v186.5215 _______________ The southern tip of Greenland is underlain by the Palaeoproterozoic Ketilidian orogen (e.g. Chadwick & Garde 1996; Garde et al. 1998a). Field investigations in the summer of 1999 were focused on the structure of migmatites (metatexites) and garnetiferous granites (diatexites) of the Pelite Zone in the coastal region of South-East Greenland between Lindenow Fjord and Kap Farvel (Figs 1, 2). Here, we first address the tectonic evolution in the Pelite Zone in that region and its correlation with that in the Psammite Zone further north. Then, the structure and intrusive relationships of the rapakivi suite in the Pelite Zone are discussed, including particular reference to the interpretation of the controversial outcrop on Qernertoq (Figs 2, 8). Studies of the structure of the north-eastern part of the Julianehåb batholith around Qulleq were continued briefly from 1998 but are not addressed here (Fig. 1; Garde et al. 1999). The field study was keyed to an interpretation of the Ketilidian orogen as a whole, including controls of rates of thermal and tectonic processes in convergent settings. Earlier Survey field work (project SUPRASYD, 1992–1996) had as its principal target an evaluation of the economic potential of the orogen (Nielsen et al. 1993). Ensuing plate-tectonic studies were mainly funded in 1997–1998 by Danish research foundations and in 1999 by the Natural Environment Research Council, UK. The five-week programme in 1999 was seriously disrupted by bad weather, common in this part of Greenland, and our objectives were only just achieved. Telestation Prins Christian Sund was the base for our operations (Fig. 2), which were flown with a small helicopter (Hughes MD-500).
