Due to a high number of specialized species and unique environmental conditions, alpine spring ecosystems are particularly vulnerable change human impact. Therefore, the assessment ecosystem integrity through habitat monitoring over long periods time is particular importance, especially in protected areas. Bioindication by conventional includes sampling whole communities morphological identific...
<p><strong>Background. </strong>The study and monitoring of water quality is commonly carried out through the characterization physicochemical bacteriological parameters. However, presence point pollutants that are discharged at times when an exact record their incidence may not be achieved, has led to exploration different methodologies in order determine a body water, one wh...
Rhodotorula aurantiaca yeasts are ubiquitous microorganisms found in water, soil, plants, etc. Since the main requirement of an indicator organism is wide occurrence nature, this species can be informative bioindicator ecological state environment. The aim was to study influence Cu (II) compounds on color carotenoid pigments intensity two Rh. strains (Y-1193 and Y-1195).
 Y-1193 strain mor...
Throughout the world, epidemiological studies were established to examine the relationship between air pollution and mortality rates and adverse respiratory health effects. However, despite the years of discussion the correlation between adverse health effects and atmospheric pollution remains controversial, partly because these studies are frequently restricted to small and well-monitored area...
S pecies whose presence or abundance readily reflect some measure of the character of the habitat within which they are found are often identified as bioindicators 1 , most frequently to monitor changes within a particular habitat. In spite of the intuitive appeal of bioindication, largely as a consequence of its cost-effectiveness in the face of urgent conservation issues, indicator studies fr...
This contribution provides summary information on the historical and contemporary significance of lampreys for human life. The unusual to bizarre appearance initially posed a problem zoologists correctly classify in zoological system. In certain places, are used as bait sport fishing, total seven species fished extensively gastronomic purposes Europe, North America, Australia, Asia. New about r...
Increasing a large amounts of sewage sludge in Ukraine is an urgent environmental problem that requires the selection effective strategy for their disposal. The usage composting technology leads to restoration as resource and cost-effective environmentally sustainable compared method landfilling. purpose this research carry out bioindication tests growth substrates based on composted with subse...
The paper presents the results of a study hypothetical evolution unicellular hydrobionts from Verhniy Kaban Lake Kazan by 18S rRNA marker gene with aim identifying species saprobity based on molecular phylogenetic analysis. is an isolated freshwater reservoir. Its coastline relatively smooth except for northern end, which forms swampy and overgrown bay. To West lake urban settlement situated to...
