The article provides information about new Pteridophyta in the North-Eastern part of the Lesser Caucasus. As a result of the development of literature and personal field research materials, Pteridophyta of the North-Eastern part of the Lesser Caucasus are characterized by 3 divisions, 5 classes, 13 families and 39 species of 20 genera. Among these species are Polypodium interjectum Shivas., Polystichum illyricum (Borb.), Cystopteris anthriscifolia Fomin., one species variety Polystichum aculatum var. aristatum, one new ecotype Adiantum capillus-veneris L., was identified as new for the studied area.

On the highlands of the north – eastern part of the Lesser Caucasus were investigated ontogenetic characteristics Cerastium davuricum in different type of plants. There are found that cenopopulation spices goes through a 4- and 10-year periods. Age composition cenopopulations species is very variable and is associated with the biological characteristics of species composition of the sward, the economic use of pastures. In research found the following types of cenopopulation: normal, invasive, regressive. Meanwhile, the predominance of vegetative individuals in the population in the first case indicates the weakness of cenopopulation, and in the second case, the high number of generative individuals indicates the sustainability of cenopopulation. This arrangement of population under less favorable conditions compared with another one.

Knowledge of the overall syntaxonomic and habitat variability of forest communities with Arolla pine (Pinus cembra) within the Tatra Mountains (Western Carpathians) is still insufficient as field research was hindered by their hardly accessible localities and deforestation for high mountain grazing. Arolla pine woodlands were traditionally classified within the association Pino cembrae-Piceetum Myczkowski et Lesinski 1974, but recent surveys recognize more numerous units. Hitherto unpublished releves from the north-eastern part of the Tatra Mountains document the occurrence of several floristically and ecologically distinct Arolla pine communities: (1) acid woodland of Homogyno alpinae-Pinetum cembrae on nutrient-poor habitats over quartzitic bedrock, and (2) calcareous woodlands of species-poor Pyrolo rotundifoliae-Pinetum cembrae of sites with a well-developed, tangled humus soil horizon, Cystopterido montanae-Pinetum cembrae on habitats influenced by both limestones and quartzites, Primulo elatioris-Pinetum cembrae bound to sites with the most favourable humidity, and Seslerio tatrae-Pinetum cembrae with the most pronounced calcareous character.

The bioecological potential and resource potential of feed plants distributed on the pastures of the North-Eastern part of the Lesser Caucasus are studied. 440 Angiosperms species belonging to 171 genera and 27 families have been identified in the flora of the territory. The biological resources relatively wet and dry mass of some species were calculated in different years and were found the reserves of the Lotus corniculatus L., Dactylis glomerata L., Anthyllis lachnophora Juz. and Urtica dioica L. species respectively — 246.55 (59.2%); 198.0 (45.5%); 149.53 (32.9%); 135.4 (28.4%) centners on ha. For farmers advisable to use both dry and wet masses to enrich in the diet of animals. So, the yield of each species in 2019 increased compared to 2017–2018 years. Indicators of feed value were also analyzed for assess the feed value of these species, common among the meadow vegetation types. The species Dactylis glomerata L. should be distinguished according to the highest dry weight and crude protein (18.0%), and Lotus corniculatus L. — by the feed unit (0.22). Cultivate the highest yielding fodder plants and studies the indicators of fodder quality are necessary for accelerate the development of animal husbandry and obtain high-quality animal products.

The genus Microgecko Nikolskii, 1907 (Gekkonidae) currently includes eight species distributed from western Iran to north-western India and Pakistan. During field research in Iraq, we found a population of the genus near to the Darbandikhan Lake in the north-eastern part of the country. Because members of the genus are characterized by a higher level of morphological and genetic diversity, we investigated the population using both morphological and molecular approaches. The phylogenetic analyses based on a fragment of the mitochondrial marker cytochrome b and morphological characters showed that our investigated population belongs to M. helenae fasciatus. This is the first record of the genus and species for Iraq. Moreover, the phylogenetic structure within M. helenae shows divergences that suggest the elevation of M. h. fasciatus to species level.

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.

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).

Geology of Greenland Survey Bulletin, 183, 23-33. https://doi.org/10.34194/ggub.v183.5201 _______________ During a five week period in August–September 1998 the poorly known north-eastern part of the Palaeoproterozoic (c. 1800 Ma) Ketilidian orogen between Kangerluluk and Mogens Heinesen Fjord in South-East Greenland (Fig. 1) was investigated in continuation of recent geological research in other parts of the orogen. The north-eastern part of the orogen is remote from inhabited areas. It is mountainous and comprises a wide nunatak zone which can only be reached easily by helicopter. Furthermore, access to coastal areas by boat is difficult because many parts of the coast are prone to be ice-bound even during the summer months, due to wind- and current-driven movements of the sea ice.
