Bangladesh's shipbreaking industry has emerged as a newly developed industry by meeting the country's major steel demand. However, harmful compounds are frequently discharged from wrecked ships and typically interact with beach sand and water, inflicting adverse effects on the coastal ecosystems and biodiversity. As a result, the ship-breaking acti...

There is a great number of lakes within the Russian territory. The majority of research is re-lated to practical needs and the conditions in large aquatic ecosystems of economic or recreational value, as well as specially protected natural objects. At the moment, the state of water bodies with high mineralization belongs to underinvestigated factor...

Zooplanktons play an important role to transfer energy from the primary level to upper trophic organisms in aquatic bodies. Naturally, in rainy seasons, a number of rain-fed ponds have occurred for short existence. These seasonal rainy ponds are sustained for a maximum of two or three months before winter. In this short period, newly introduced rai...

Aquatic life is supported by phytoplankton, that constitute the aquatic food chain and form a link between the producers and consumers. They provide food for the primary consumers, which include zooplankton, shellfish, and fish. The ecological health of the aquatic ecosystem is also monitored with the aid of plankton, which serves as a bioindicator...

Freshwater Algal Assemblages in Seasonal Ponds: An Opportunity in Coastal Agriculture and Aquaculture

The current paper aims at analyzing the species structure of the phytoplankton community of two reservoirs on the territory of South Ural.

Zooplankton are found very sensitive to even slight aquatic pollution due to a number of chemical imbalances in freshwater bodies. As an amazing tiny creature zooplankton play a very crucial role in the aquatic food chain by transferring energy from primary levels to tertiary organisms. For many years it has been well established that zooplankton a...

Risk assessment models described by United States Environmental Protection Agency (USEPA) was applied. The concentrations of metal(loid)s in the indoor dust determined in p...

Gastropods have long been used as biomonitors of the contamination caused by heavy metals (HMs) in aquatic environments. The main aim of this study was to investigate the possibility of using three species of gastropods (Contectiana listeri, Lymnaea stagnalis and Bithynia tentaculata) to monitor HMs (Cu, Zn, Mn and Fe) concentration in the lakes of...

The metal(loid)s content in the environment is one of the important issues in the environmental management. The metal(loid)s may be present in the both from naturals like natural components of the Earth's crust and anthropogenic sources as human activity effects. Some metal(loid)s are toxic and dangerous for the environment. Chelyabinsk was chosen...

This paper deals with mermithid nematodes (Nematoda: Mermithidae) richness of the South Ural region, Russia.
