The intrinsic link between ecosystem health and human health has been firmly established in the literature and has given rise to the development of new multidisciplinary fields of research such as medical geology. An important practical implication of the ecosystem health approach is the utility of human disease outbreaks as indicators of underlying ecosystem disruption. The use of such a bioin...
Abstract Discharge of untreated industrial effluents has been associated with soil contamination. Biochemical alterations in Lumbricus terrestris and remediation capacity Azadirachta indica tree from effluent discharge locations Challawa (A B) Kura village (control location C) were assessed. Levels nitrate, phosphate, iron, chloride, hardness at A B significantly ( p < 0.05) higher than thos...
Bioindicators are useful for determining nutrient regimes in marine environments, but their ability to evaluate corals reefs different ecological states is poorly understood. The precision, availability and congruency of eight potential bioindicators (brown macroalgae, green turf algae, cyanobacteria, soft corals, zoanthids, sponges, sediment) stable isotopic elemental signatures (δ15N, δ13C, %...
Nematodes are among the most abundant organisms on Earth, and have important roles in terrestrial, freshwater, marine ecosystems. Free-living nematodes been used successfully as indicators of biological health ocean pollution for at least past 40 years, but their use bioindicators is not ubiquitous. They often specifically heavy metal hydrocarbon pollution, with far fewer instances biological, ...
The main goal of this study was to examine the use of cyanobacteria for evaluating the quality of running water. Accordingly epilithic cyanobacterial communities were collected in Dez River and Ojeyreb drain in south of Iran. Samples were collected in two seasons: autumn and spring. Effective physical and chemical factors on the structure of cyanobacterial communities and the dispersion of the...
Bioindicators are species used to appraise the health conditions of the environment or ecosystem and they are capable of determining the environmental integrity using their functions and populations. In preserving and managing the natural surroundings, it is imperative to monitor the condition of many components of the ecological unit. Under normal circumstance, conservation advocators would be...
