Sewage treatment by bacteria and algae. iii. Eutrophication and phosphorus pollution. iv. Management of metal pollution. v. Immobilized cells in the management of pollution. i. Atmospheric CO2 Reduction: The lower atmosphere contains [...]
Read this article to learn about the basic concepts, sources and nature of environmental pollution. Environment may be consider as our surroundings which includes everything around us, i.e. the non-living (abiotic) and living (biotic) environment. The abiotic environment consists of air, water and soil, while the biotic environment includes all the living organisms (plants, animals, microorganisms) that we regularly come [...]
Fragmentation of habitat and patchiness may affect various individual, population and community level processes. Endeavors of ecologists and conservationists to protect wildlife populations in such habitats have resulted in various conservation theories and management options. One early theory—the theory of island biogeography—was proposed by McArthur and Wilson (1967). The theory of island biogeography states that in a fragmented community, the [...]
