Soil fertility is determined by biological diversity at all levels of life, from genes to entire biocenoses. The aim this study was evaluate bacterial in soil contaminated with Cd2+, Co2+ and Ni2+ sown Brassica napus. This an important consideration because soil-dwelling microorganisms support phytoremediation minimize the adverse effects heavy metals on environment. Microbial counts, influence...

Plants are natural sources of bioactive compounds, and the intensive use wild plants to obtain them, in particular secondary metabolites, depletes biocenoses. Instead, modern biotechnological methods, especially cell tissue culture vitro, make it possible get environmentally friendly, highly productive plant raw materials that able synthesize accumulate specialized substances, which valuable fo...

The Asinara Island Marine Protected Area (AMP) (Sardinia, Italy) represents one of the most uncontaminated areas Mediterranean Sea and, therefore, but misses an accurate mapping biocenoses and associated lithologies present on sea floor. provided map has highlighted presence 21 laying rocky or sandy substrate if shallower deeper respectively. recurring are: Posidonia oceanica L (Delile) coralli...

Topicality. The article provides information about the species composition of spiders in Tyligul estuary Odesa region. Aim. Study araneofauna various biocenoses estuary, Methods. Standard methods collecting were applied. We used Barber soil traps, hand collection, mowing with an entomological net. Results. During research period between 2016 and 2020, 57 from 22 families discovered, among them ...

An analysis of the species composition vegetation on fallow plots different duration and virgin lands made it possible to conclude that succession state with increasing age. Comparison zootechnical parameters hay from experimental agrocenoses average content fat, ash fiber for variants is 17.0%, 9.8% 7.7%, respectively, higher than in variant. Analysis chemical showed concentrations nitrogen, c...

An analysis is undertaken to reveal the role that various processes in living and nonliving nature play in the establishment of the chemical composition of the atmosphere and the temperature balance of the Earth. An inference is made that the biospheric mechanisms of CO2 removal from the atmosphere are insufficient in the situation of the current anthropogenic impact and the existence of potent...

The interannual dynamics of dissolved forms carbon and nitrogen in the habitat zone marine coastal plant communities has been studied waters Peter Great Bay, Sea Japan/East Sea, with different levels eutrophication, summer. An analysis obtained data based on selection functional models by statistical methods shown that contents total carbon, as well organic inorganic have a nonlinear pattern. h...

An algorithm is presented for the construction of an asymptotic approximation a stable stationary solution to diffusion equation system in two-dimensional domain with smooth boundary and source function that discontinuous along some curve lying entirely inside domain. Each equations contains small parameter as factor front Laplace operator, result, singularly perturbed. In vicinity curve, has l...
