METHOD OF SKETCHES IN ARCHAEOGENETICS AND BREEDING OF AGRICULTURAL PLANTS
DescriptionThe issues associated with visualization images of the examined object and the method of sketches or visual notes have been discussed in the article. The images of lagenaria (bottle, shape pumpkins or gourds) in works of art and agrobotanic illustration as a research tool have been selected, with the aim to conduct a visual analysis of the morphological characteristics of bottle gourd for further application of the knowledge gained in archaeogenetics and plant breeding. The article presents images of plants of lagenaria for the period from 1311 to 2014 years. Visual analysis of the morphological characteristics of lagenaria on the basis of visual notes allowed us to identify several key points: the polymorphism of fruits and different duration of the vegetation period, particularly of the reproductive system, which is characterized by different proportions of male and female flowers, the presence of pollinators, night flowering, fruit pubescence on the first stages of development, polymorphism seeds, features maturation based on the size and weight of the fetus. Understanding the range of individual development allows the breeder to submit a complete selection issue, search for new signs will touch the ancient forms of the object, diseases, pests, images which have remained only on the pictures. In our opinion, the method of visual notes can be successfully used in the educational process because it stimulates creativity and cognitive activity of students to search for information about the studied object and its reflection

SMALL MAMMALS OF THE TAMAN PENINSULA
DescriptionIn the present study, fauna of small mammals of the Taman Peninsula is analyzed. It is shown that the complex of rodents and insectivores inhabiting the study area differs considerably from the adjacent continental areas and is an isolate. Structure of its fauna and population resembles that of the steppe parts of Crimea and, at the same time, North-West NearCaspian areas. Analyses of variation of the D-loop regions of mtDNA in yellow-bellied mouse Sylvaemus witherbyi, as well as certain peculiarities of the species diversity, show the priority of faunal and genetic connections of the Taman Peninsula’s mammal fauna with the North-West Near-Caspian one

THE STEPPE RIVERS OF KUBAN, STATE OF THEIR BIOTA AND PROSPECTS OF DEVELOPMENT
DescriptionThe steppe rivers of Kuban, which form their landscapes in the space between the basins of the rivers Don and Kuban, are divided into two subtypes: the rivers of internal flow which flow into the small ponds (Panura, Kirpili et al.), and the rivers of external flow which flow into the Sea of Azov (Eja, Beysug, Chelbas); direction of flow of these rivers is defined slightly downward from the high right bank of the Kuban (up to 50m) and the eastern slopes (altitude up to 50-170m) of Stavropol Upland; shores of rivers are heavily deforested, subjected to strong anthropogenic pressure and water systems contaminated of organic substances. Plowing of catchment areas to foreshore and plowing dry beams, as well as cutting of forests caused huge harm of river systems. The qualitative composition of microorganisms is not very varied. Polluted rivers and bottom sediments are dominated by saprotrophic microorganisms, spore-bearing and other rod-shaped bacteria. In the samples of sludge we marked high titer thiobacteria and sulfate-reducing bacteria. Complex of actinomycetes was investigated. The species composition of vascular plants includes 135 species from 48 families, most numerous asteraceae, cereals and legumes. The dominant plant of many floodplains steppe rivers is common reed, which contributes to the process of silting soil particles from the fields and the destruction of the sod with overgrazing. Among phytocenoses there is a domination of reed grass-forb deposits on moist soils, mesophilic couch grass-forb and grass-forb xerophytic. In soil biota of floodplains it is dominated by oligochaetes, bottom fauna molluscs and oligochaetes, water - rotifers and cladocerans

Description
The Mavrostifo – Greece aboriginal variety. It is belong to the group of varieties convar. pontica subconvar. balcanica Negr. The time of production period is 156-165 days. The variety of medium height. The degree of ripening of vine is higher. The yield is higher. The average mass of bunch is 360 g. It has higher drought-resistance and middle steadiness for mushrooms diseases. The leave is large, black-green, the middle dissection, five lobes (the lobes are recovered), from bottom side with a lot of hairs. There are two blossoms on the 3 and 4 nodes. The flower is hemofroditus. The bunch is low or big, long, conical-winged, density. The berry is average, round, black-blue. The pulp is juicy, with tasty variety after taste. There are two-three seeds in berry. The sugariness is higher. The variety is useful for preparing higher quality intensive colored red wines of different categories from southern zones of viticulture with warm and dry climate.
