Articolul prezintă rezultatele studiului indicatorilor calitativi și cantitativi ai fitoplanctonului în fluviul Nistru limitele Republicii Moldova perioada anilor 2020-2024. Algele planctonice din au fost reprezentate de 106 specii şi varietăţi alge care se referă la 5 grupe taxonomice: Cyanophyta(Cyanobacteria), Bacillariophуta, Pyrrophyta, Euglenophyta, Chlorophyta. Conform rezultatelor investigațiilor efectivul numeric al a variat 0,43-42,03 mln cel./l, cu biomasă 0,52-17,58 g/m3....
Articol prezintă rezultatele studiului indicatorilor calitativi și cantitativi ai fitoplanctonului lacului de acumulare Dubăsari în anul 2024. Baza floristică a algelor planctonice fost reprezentată 56 specii şi varietăţi intraspecifice alge care se referă la 5 grupe taxonomice: Cyanophyta (Cyanobacteria), Bacillariophуta, Pyrrophyta, Euglenophyta, Chlorophyta. Conform rezultatelor investigațiilor, efectivul numeric al variat limitele 1,94-18,82 mln cel./l, iar biomasa –0,98-12,01 g/m3,...
Reliable taxonomy underpins communication in all of biology, not least nature conservation and sustainable use ecosystem resources. The flexibility taxonomic interpretations, however, presents a serious challenge for end-users concepts. Users need standardised continuously harmonised reference systems, as well high-quality complete data sets, but these are generally lacking non-specialists. solution is dynamic, expertly curated web-based tools. Pan-European Species-directories Infrastructure...
The biomass of plants from the Cuciurgan cooling reservoir Moldovan Thermal Power Plant is dependent on thermofication and bore considerable modifications. contents many metals in aquatic were highly correlated with their water: r=0,87-0,91. dynamics trace element accumulation depends seasonal factors. From beginning spring to end summer autumn, concentrations elements increased by large increments, while decrease temperature below 10°C, an opposite effect was observed. After plant death, a...
The study presents the results of investigations regarding use microalgae species Chlorella vulgaris Beijerinck 1890 and Oscillatoria amphibia C. Agardh ex Gomont 1892 as a food source for population Paramecium caudatum Ehrenberg, 1834. demonstrate how different concentrations algae cultures influence cellular reproduction parameters in caudatum. Low stimulate growth, while high have negative effect on paramecia population. can be effective small doses to growth short-term productivity,...

Introduction. An important aspect of research in the field microbial ecology is understanding interactions between organisms, particularly influence they have on one another within aquatic ecosystems. Green microalgae (phylum Chlorophyta) represent a diverse group photosynthetic playing significant role ecological cycles. Investigations focused evaluating impact two species, Chlorella vulgaris and Scenedesmus quadricauda, growth parameters natural population Paramecium caudatum, making it...
The reintroduction of Eurasian beaver (Castor fiber) in Romania started 1998 and was a complete success terms population natural range enlargement.The habitat modelling capacity more obvious once with the increase densities, demonstrating high potential this species to create new trophic niches for other implicitly biodiversity enrichment.The study conducted on floodplain area near Bârsa River, where became vegetation fauna paradise, by constant intervention beavers that had colonized...
The fishing regulatory measures in the Republic of Moldova that have been applied over years natural ecosystems not always effective - either through faulty organization exploitation fish resources, non-compliance with regime, failure to assess state ineffectiveness ameliorative etc., or imperfection normative framework. Regardless causes generate and maintain such a situation, it is certain quality efficient renovations are needed, based on fundamental scientific research. Thus, present...
Water quality is one of the key factors in maintenance fish health. The current article revises effects various water parameters on health, methods analysis and diagnosis as well for improving ponds, aiming to reduce health risks. synthesis a joint work an international consortium formed from scientists Institute Zoology Ion Ionescu de la Brad Iasi University Life Sciences, which allows broader view issue identification sustainable solutions farmers Republic Moldova Romania.
Articol prezintă rezultatele studiului indicatorilor calitativi și cantitativi ai fitoplanctonului râului Prut pe teritoriul Republicii Moldova în perioada anilor 2020-2023. În compoziția fitoplanctonul au fost identificate 101 specii. Conform rezultatelor acestor studii, s-a stabilit că format principal din algele diatomei verzi. Efectivul numeric a variat limitele 0,33-26,14 mln. cel/l cu biomasă 0,42-20,63 g/m3. valorilor biomasei râul poate fi atribuit categoriei ecosistemelor...
The article describes the results of long-term research on dynamics vanadium migration in water, bottom sediments, higher aquatic plants, invertebrates, and fishes cooling reservoir Moldovan Thermal Power Plant.An obvious dependence level ecosystem quantity composition burnt fuel at plant was established.In most cases system "water -silts" occured from water layers to sediments.But if intensity sulphate reduction putrefaction processes increases concentration dissolved oxygen decreases...
Based on the multi-annual studies conducted in aquatic ecosystems of Republic Moldova, have been developed scientific and practical recommendations regarding prevention reduction active eutrophication phenomenon country. One environmentally friendly method, economicaly efficient advantageous is use macrophytophagous restorative phytoplanktonophagous fish species.
The article presents the results of investigations on diversity and quantitative structure phytoplankton different types aquatic ecosystems within Republic Moldova during 2010-2015. invasive species (native) Merismopedia tenuissima Lemmermann 1898, Synechocystis aquatilis Sauvageau 1892 Aphanizomenon flos-aquae Ralfs ex Bornet & Flahault 1886 from composition were identified. potential growth these can lead to algal blooms. Following our investigations, it was established that biomass...
In the lower Dniester, polyploid females of hybrid complex Cobitis taenia are a portion spawning species with asynchronous development germ cells during entire breeding period. The season in this water basin begins second decade May and ends July. population, parallel females, hermaphrodite individuals also present, which ovary zone is functional, testis sterile. A decrease relative mass gonads subsequent generations was noted, leads to consistent value gonadosomatic index, before third spawning.
The article presents the results on qualitative and quantitative indicators of phytoplankton Prut River lower sector within Republic Moldova in 2018-2020. In compositions 72 species were identified. Seasonal long-term patterns development have been established sector. numbers changed limits 1,06 to 20,32 mln. cell/l, with biomass 1,23-21,64 g/m3. values saprobic indexes, estimated basis species-indicators (52 species) from composition, which are proportion 58% typically β-mezosaprobic,...
