A geobotanical survey of rich fens on the left-bank terraces of the Em-Egan River, the right tributary of the Malaya Sosva River in the southern part of the nature reserve “Malaya Sosva” (61.79° - 62.05° N, 64.06° - 64.55° E). 179 species have been identified, including 84 species of higher vascular plants, 69 species of mosses and 26 types of liverworts. Of these, 11 species are included in the Red Data Book of the Khanty-Mansi Autonomous District, including 9 species of higher vascular plants and 2 species of mosses: Baeothryon alpinum, Cardamine nymanii, Dactylorhiza traunsteineri, D. incarnata, Hammarbya paludosa, Huperzia selago, Saxifraga hirculus, Thelypteris palustris, Triglochin palustre, Meesia triquetra, Paludella squarrosa. Three more species – Corallorrhiza trifida, Calliergon richardsonii, Meesia uliginosa are included in the list of species whose condition in the natural environment requires special attention. In addition, such rare species as Eriophorum brachyantherum, Stellaria crassifolia, Bistorta major, rare species of mosses such as Bryum bimum, Calliergonella cuspidata, Campylium pretense, Hamatocaulis vernicosus, Scorpidium cossonii, Tomentypnum nitens are listed in the mire plant communities. On the basis of the ecological-floral approach of the J. Brown-Blanke school, 8 associations, 6 subassociations and 3 communities from 5 unions, 3 orders and 3 classes of vegetation were allocated in the vegetation cover of rich fens. The belonging of one more vegetation community type of the Bistorta major–Sphagnum fuscum dwarf birch community with the sparse fir (Picea obovata) to the class and the order is not established. The highest phytocenotic diversity and the highest concentration of rare and protected species are found in communities of the order Sphagno warnstorfii-Tomentypneetalia. Phytocenotic association and frequency of occurrence of rare species in different types of plant communities are established.

Data on findings of seven species of vascular plants that are new records for the spontaneous flora of the Left Bank Forest-Steppe zone of Ukraine are presented. Four species (Artemisia umbrosa, Sedum album, Ribes aureum, and Prunus tomentosa) are alien plants completely naturalized in the studied area; other three species are treated by author as representatives of the indigenous fraction (Cerastium kioviense, Rhododendron tomentosum, and Vicia lathyroides). Cerastium kioviense and V. lathyroides are considered not rare species in the studied region but rather overlooked by botanists due to their early flowering period. Four species (A. umbrosa, C. kioviense, R. aureum, and P. tomentosa) were for the first time found in Poltava Region, two species (R. aureum, P. tomentosa) – in Kharkiv Region, and one (V. lathyroides) – in Kyiv Region. For all reported species, lists of their localities, places of original descriptions and nomenclatural types are indicated. The species name Prunus tomentosa is lectotypified.

The Way

The contemporary condition of soil cover in Ukraine is characterized. The attention is focused onto widespread degradation processes in soils. The causes that determine the development of these negative processes are considered. The contemporary informational support for the condition of soil cover in Ukraine is estimated. In general, the current available information is of narrow-departmental nature, obtained by different methods and non-correlated monitoring programs. As a rule, it is stored in under-structured databases, incompatible with other information systems; mainly recorded on paper media unusable with modern technologies, whereby such information resources are diffi cult to be compiled together. These disadvantages are strong constraints against consistent usage of materials for evaluation, forecast and management of changes in the soil cover. The Soil Observation program should thereby be combined with Agrochemical Passportization and ecology-ameliora- tive monitoring; in other words, the application of innovative soil-agrochemical methodology is considered. Each individual type of surveys shall complement the others, and taken altogether, they shall constitute a con- sistent Information System, capable of solving the problems of assessing the condition, forecasting, manage- ment, usage and protection of soil resources. The monitoring procedures should be conducted on the basis of a new soil concept in line with unifi ed programs and methods, so as to meet European approaches to the maxi- mum extent. Such a technical composition enables getting information on present-day processes in soils, and is the only combination that actually helps us to “ecologize” our knowledge of soils, which is the leading trend in the scope of global soil-science. Thus obtained results will serve as a State-owned tool which would subse- quently facilitate the use and protection of soil resources all over the country, to be involved in a united global soil-information scope. The attention is focused onto social signifi cance of the information on soils and their fertility in terms of land resources optimization, as well as the formation of sustainable land use in Ukraine. Aim. To demonstrate the long-term effect of different ways of tillage of typical low-humus chernozem on the change in humus content and composition and the direction of transformation processes of organic fertili- zers. To study the changes in the structure of energy reserves in group and fractional composition of humus in typical low-humus light-loamy chernozem of the Forest-Steppe of Ukraine. Methods. Field, laboratory, microbiological, computational, mathematical and statistical. Results. It was determined that in conditions of long-term subsurface tillage the most effi cient humus accumulation occurs in the 0–20 cm layer of chernozem with simultaneous increase in its content in the lower part of the processed layer without any accumulation differentiation. Surface tillage leads to expressed differentiation in humus accumulation in the 0–20 cm layer of soil (0.005 % per year). When 6 t/ha of humus are replaced by 7 t/ha of by-products the intensity of humus accumulation is decreasing regardless of the way of tillage, but humus accumulation was found to be the most effi cient for subsurface tillage. The application of subsurface tillage leads to the increase in the ratio of C HA : C FA , which is conditioned by the increase in the humifi cation of plant remains of by-products in the 0−20 cm layer of soil by 110–112 % – for subsurface tillage, and by 105 % – for surface tillage. Conclusions. It was established that systematic subsurface tillage of typical chernozem of the Left-Bank Forest-Steppe of Ukraine leads to the structuring both of the total reserves of energy С org , and its quality content, aimed at the increase in the intensity of the processes of humifi cation and accumulation of organic carbon, and the decrease in miner- alization. The ratio of energy reserves С org of humic acids to fulvic acids in the 0−30 cm layer of chernozem is 1.85−1.87 regardless of the way of tillage, which testifi es to the repeatability of humus accumulation, but the total reserves of energy С org was higher for subsurface tillage (+ 31 Teracalorie/ha) compared to deep plough- ing. As for the surface tillage, the energy enrichment was at the level of deep ploughing.

High Productivity

There showed the productivity, chemical composition of feed and the timing of mowing of grass and variety mixes of permanent grasses on drained peat soils of Left Bank Forest-Steppe of Ukraine. The presence of early rip­ ened seeded grass provides a uniform supply use mowed mass from middle May until the end of September and the productivity of lands, which ranges from 10 to 14 t/ha of dry weight, metabolizable energy – 100.0 – 130.0 GJ and feed units 7-11 t/ha. Additional manuring of N90 on the background Р45К120 is effective at the start of second year of use. On the organization of hay conveyors of different ripening time herbages is possible to extend the optimal tim­ ing of mowing of green mass to 25-35 days. Best among the early-maturing grass crops are Dactylis glomerata va­ riety Kyivska rannia-1 with Alopecurus pratensis variety Sarnenskiy ranniy or its mixture with Bromus inermis and Festuca pratensis. With medium ripening – pure sowing eastern fescue of variety Lyudmila, Phalaris arundinacea variety Sarnenski-40, Bromus inermis variety Arsen and their compounds. High productivity of late-ripening herb­ age is provided by the inclusion in the composition of grass mixtures of Phleum pratense L. variety Vyshgorodska and Dactylis glomerata of variety Ukrainka, and Agrostis gigantea Roth variety Sarnenska piznia. It is also possible organization hay conveyors of different ripening varieties of Dactylis glomerata varieties Kyivska rannia, Muravka, Ukrainka.

With the ever growing population and economic needs of Mauritius, the flora of Mauritius has never been in more danger and one group of vascular plants is even more in peril; ferns.<em> Diplazium proliferum</em> is indigenous to the Mascarene region and is considered as a rare species in Mauritius. The need to develop a tested <em>in vitro</em> propagation protocol is a must to protect the biodiversity of Mauritius. This experiment was geared towards the establishment of a proper sterilization technique and the effect of 6-benzylaminopurine (BAP) and light on <em>in vitro</em> culture of this fern. Sterilization with 0.05% Mercuric chloride was effective to eliminate fungal contamination and allow germination of spores. Culture media supplemented with BAP did not significantly increase growth rate of both gametophytes and sporophytes of<em> D. proliferum</em>. Present results suggest efficient sterilization methods to be a crucial stage for successful<em> in vitro r</em>egeneration of ferns. The established protocol will be used as an optimized baseline protocol for the propagation of other indigenous ferns.

The anthropological composition of the population buried at the cemetery of the Scythian Age near Svitlovodsk city (Kirovograd region) is analyzed in the paper. The burial ground is located on the border of the Forest-Steppe and Steppe Zones of the Right Bank of the Dnieper. The anthropological material under study comes from cemetery without mounds. Archaeologists date the main massif of burials to the 4th century BC. The anthropological composition of the population that was buried at this burial ground was not homogenous. The male series of skulls is characterized by a long, medium-wide, high, dolichocranic skull. The face is of medium size, it is mesognathic. The horizontal profile of the face at the upper level is medium, but with a tendency to the sharp; at the middle level, the face is strongly profiled. The orbital and nasal indexes are medium. The bones of the nose are moderately protruding. The average characteristics of the male population fit into the range of variations of the Scythian series. The male series belongs morphologically and statistically to the circle of the steppe Scythian groups. The male group from the burial ground near the city of Svitlovodsk is close to the series from the Nikolaevka burial ground on the Dnister River, the group of skulls from the burial mounds near the village of Shirokoe (Left Bank of the Dnieper River), the group of skulls from the burial mounds near the village of Vyshchetarassivka, a series of skulls from the Mykhailivka burial ground. Of the forest-steppe series, only the combined group of skulls from the Trypillya region is somewhat close to it. All these statistically and morphologically similar groups originate from different territories. This illustrates the specifics of the settlement and demonstrates the mobility of the Scythian groups. The female series from the burial ground is characterized by a long, narrow, medium-high skull, mesocranic in shape. The size of the face is small, it is mesognathic. The horizontal profile of the face at the upper level is moderate, at the zygomaxilar level it belongs to the category of sharp, but with a tendency to moderate. The orbital index is medium, the nasal index belongs to the large category. The bones of the nose are medium protruding. The female series from Svitlovodsk burial ground turns out to be the most gracile among the Scythian series in Ukraine. For this reason, it differs significantly from the entire massif of the steppe Scythian series. The closest to the Svitlovodsk series is a group from mounds near Nikopol.
