By the methods of classical histology and modern histochemistry in differential assessment of various albuminous components, we have revealed a number of new regularities of age dynamics and distribution of some albumen in cells and tissues of musky preputial glands of muskrat males inhabiting under conditions of Baikal region ecosystem
In the article, we gave the review of the results of histological research of the biologically active skin points of the thorax of dogs. The results of the morphology of the skin with the biologically active spots and without them were discussed
In the given work there is information about peculiarities of distribution and phytocenotic placement of the endemic of Dagestan flora Helianthemum daghestanicum Rupr. Twenty five
locations of the species are detected and four of them are new ones. Altitude levels of its spreading are defined more accurately – 350 – 1750 m. It is notified that basic types of vegetation, where Sunrose Dagestanian can be met, are communities of mountainous xerophytes and mountain steppes with domination of Botriochloa ischaemum and Salvia canescens
This article presents the results of researching impact of contaminant absorption with pathological state of tree species in extreme condition of Voronezh reservoir near-shore
The article presents the results of studying the
growth-stimulating activity of the microorganisms of
the genus Bacillus of leaf surface microflora arboreal
plants in Stavropol. Isolated and identified strains of
epiphytic microorganisms of the genus Bacillus with
the leaf surface of plants: Quercus robur L., Carpinus
caucasica Grossh., Fraxinus excelsior L., Acer
campestre L.. Growth stimulating properties of 43
strains of aerobic spore-forming bacteria (Bacillus
subtilis, Bac. megaterium, Bac. pumilis, Bac. cereus,
Bac. Licheniformis) are researched. Selected strains
are potentially promising in the development of
microbial preparations for plants. A regional
collection of strains of epiphytic organisms was
formed
Study results of Crambe maritima L. growth and development at introduction in Botanical garden of SFU are presented in article. It was revealed that the life cycle of majority specimens lasts three years. Results the ontogenetic and phenologic studies testify about success of primary introduction of Crambe maritima
In this article we present data on the effect of addition
of mineral nutrition elements in the structure of the
phytoplankton community in the north-eastern part of
the Black Sea in the different seasons. Experimental
studies have shown that the increase in biomass of
microalgae occurs at the simultaneous addition of
nitrogen and phosphorus in the accumulative cultures.
In the spring can get biomass Emiliania huxleyi,
P.pseudodelicatissima, Chaetoceros curvisetus and
Skeletonema costatum, in the summer – E. huxleyi, C.
curvisetus, P.pseudodelicatissima, S.costatum,
Thalassionema nitzschioides, Leptocylindrus danicus,
Dactyliosolen fragilissimus, Proboscia alata,
Pseudosolenia calcar-avis, in the autumn - C.
curvisetus, S.costatum, Th. nitzschioides, L. danicus,
D. fragilissimus
