First Time

Indicators of biological activity (humic content and stock, Cmic content and stock, hydrolytic and redox enzymes activity) were measured for the first time in the upper horizons of mountain meadow subalpine soils of Central Caucasus (elbrus altitudinal zonality in Kabardino-Balkaria). The comparative assessment was performed for the biological characteristics together with soil density and acid-base properties for soils of natural and pasture ecosystems. The integral index of ecological and biological soil state (IIEBSS) was calculated to estimate the level of changes in biological activity. It was shown that pasture degradation leads to 30% decrease of IIEBSS compared to the undisturbed soil. The defined biological parameters of natural undisturbed mountain meadow soils could be used as diagnostic indicators for the ecological studies of ecosystems under anthropogenic load.

New Association

A new association Artemisio chamaemelifoliae—Plantaginetum atratae is described from the subalpine belt of the Central Caucasus. Its diagnostic species are Artemisia chamaemelifolia, Plantago atrata, Salvia verticillata, Potentilla pimpinelloides. The association is probably affiliated with the class Festuco-Brometea Br.-Bl. et Tx. 1943and the order Festucetalia valesiacae Br.-Bl. et Tx. 1943, as is testified by a high proportion of species diagnostic of these syntaxa in the composition of the studied communities. If compared to syntaxa of the true subalpine meadows of the study area, reported earlier (Цепкова, 1987), the association is distinguished by the absence or single occurrence of Festuca varia in the composition of its stands as well as by the absence of Calamagrostis arundinacea, Betonica macrantha, Centaurea cheirathifolia, and Silene ruprechtii in the diagnostic species set. The differentiation from the post-forest meadows is provided by the presence of the xero-mesophyte Phleum phleoides and the xerophytes Artemisia chamaemelifolia, Astragalus oreades, A. captiosus and Teucrium orientale.

Soil Indicators

Intensive recreational, agricultural and logistics land use in uplands leads to their transformation and degradation. Subalpine meadow ecosystems of Central Caucasus are traditionally used for grazing and mowing. The work determined the current state of soils on pastures (mountain meadow-steppe subalpine soil and mountain meadow subalpine soil) and the level of changes of their properties under different stages of pasture degradation were defined. The efficacy of 4-stage assessment system for evaluating the pasture degradation of grasslands dominated by Bromus variegatus M. Bieb. was shown for the assessment of soil cover condition. The reduce of estimated soil indicators and degradation of soils under pastures with maximal degradation stage (DS3) of meadow ecosystems was statistically significant.

Type Particle

We have reported the maturation of an intracisternal A-type particle in murine plasma cell tumor cultures and three human tumor cell cultures (rhabdomyosarcoma, lung adenocarcinoma, and osteogenic sarcoma) after IUDR-DMSO activation. In all of these studies the A-type particle seems to develop into a form with an electron dense nucleoid, presumably mature, which is also intracisternal. A similar intracisternal A-type particle has been described in leukemic guinea pigs. Although no biological activity has yet been demonstrated for these particles, on morphologic grounds, and by the manner in which they develop within the cell, they may represent members of the same family of viruses.
