Forest cenosis, unlike herbaceous, is characterized by high productivity and reserves of decomposed organic material (Bazilevich et al., 1986) and less favourable climate conditions for microbial activity in forest soils, as compared to arable soils.
This is due to a large quantity of cereals in agrocenosis, compared to forest cenosis. It is known that phytoliths are amorphous silica microbiomorphs.
This suggests that the main cenosis
creator and dominant as wood and grass-shrub layer can only be the CPU types that exhibit high tolerance to most of the environmental factors considered.
The MW biological effect depends on the mineralization degree, chemical composition, presence of biologically active components and compounds, as well as on their microbial cenosis
' metabolic products.
According to Artamonova (2002), soil fungi actively participate in the biological cycle in northern ecosystems, while bacteria and actinomycetes dominate in the south in the structure of microbial cenosis
. The author also identifies particular species of microorganisms in the functioning of various ecosystems.
Arrays of Phlojodicarpus sibiricus (Steph.) K.Pol., Z.i%iphora bungeana Gus, dominant in the sagebrush-forb cenosis
, take place on the stony-gravelly soils on the slopes of hills in the North-Kazakhstan region.
At the territories adjecent to large forestlands (Nevskij forest park, districts near Lake Sestroretskij razliv, Morskaya railway station, North and South cemeteries) a cenosis
structure close to the natural one has preserved.
Over five years, Montreal-based Cenosis
has developed a range of editorial, advertising and Web publishing software for more than 50 customers, at least five dailies among them.
The conducted study showed that the species composition of the flora of the "Small Pinewood" ecological path is rich and varied enough, indicating the stability of the existing plant cenosis
. Anthropogenic impact on this area is essential, especially in the summer, on weekends, and public holidays, though visitors are mostly moved by road and path network.
Belonging to another than typical form morphologic and ecological group is has the possibility to inhabit the same biotopes , but in conditions of cryolite zone of Yakutia both forms are being observed only in flood land cenosis
and rarely in watersheds .
