The inhibitory effects of heavy metals on self-purification processes in surface water were studied. Toxicities of the metals were evaluated on the grounds of the results of the Biochemical Oxygen Demand (BOD) test in river water.

Climate change is one of the most crucial ecological problems of our age with great influence. Seasonal dynamics of aquatic communities are

In our study we investigated two polluted rivers of Eurasia from silicate and carbonate regions. We revealed an algal diversity consisting of 184 algal species and cyanoprokaryotes in the Rudnaya River, and 175 in the Qishon River. The distributions of species over the 7 higher taxa were very similar for both rivers with diatom prevealing.

Climate change has been identified as one of the greatest challenge by all the nations, government, business and citizens of the globe. The threats of climate change on our green planet

One of the adverse effects of climate change is the proliferation of heat waves. Our investigations show that according to the most widely accepted climate change scenarios heat waves are expected to be essentially longer and hotter than in the past. It might happen that events we now define as heat waves last through entire summer.

Aerial extent and distribution pattern of seagrass meadows in the Mandapam group of islands viz. Pamban area of Rameshwaram, Krusadai, Pullivasal and Pumarichan Island of the Gulf of Mannar

Desertification involves many countries featuring different ecological, economic, and social conditions. In Mediterranean Europe, high human pressure, economic development, and climatic changes combine to produce land consumption, soil erosion, salinization, and fire risk, all considered as key factors to start desertification processes.

Trace metal contents in zooplankton samples were estimated as a part of Marine Research-Living Resource Programme (MRLR) programme at 24 stations to establish the importance of these

Higher atmospheric CO2 concentration may influence positively plant production once the substrate for photosynthesis and gradient increase between the ambient air and mesophyll cells.

In view of the environmental problems generated by large-scale production of fly ash, increasing attention is now being paid to the recycling of fly ash as a good source of nutrients. Because
availability of many nutrients is very low in fly ash, available ranges of such nutrients must be improved to increase the effectiveness of fly ash as a soil amendment. In our experiment, we assessed the possibility of increasing total nitrogen, total phosphorus, total potassium and micronutrients in fly ash through
