Environmental bacteriophages: viruses of microbes in aquatic ecosystems

Since the discovery 2-3 decades ago that viruses of microbes are abundant in marine ecosystems, viral ecology has grown increasingly to reach the status of a full scientific discipline in environmental sciences. A dedicated ISVM society, the International Society for Viruses of Microorganisms, (http://www.isvm.org/) was recently launched. Increasing studies in viral ecology are sources of novel...

Biogeography of aquatic microbes

Aquatic microbes, like all organisms, have biogeographies, but this subject has attracted relatively little attention. In this review, recent results exploiting techniques of molecular biology are summarized to place in perspective the studies of this Theme Section. The studies considered concern large-scale patterns of spatial distribution among heterotrophic planktonic prokaryotic and eukaryo...

Helminthic Parasites as Heavy Metal Bioindicators in Aquatic Ecosystems

Abstract         Heavy metals have raised one of the most important problems in ecology and organisms life especially human being and animals. A variety of indicators including tissues of fish, birds and sediment have been used recently to measure the aquatic pollution with heavy metals. The aim of this study was to search the published articles in Iran a...

Caffeine as an environmental indicator for assessing urban aquatic ecosystems.

This study aimed to evaluate the co-occurrence of caffeine and the extent of its influence as compared to other traditional water quality parameters (microbiological and physico-chemical) in order to characterize it as an efficient indicator of anthropic pollution of urban aquatic environments. Caffeine is an ingredient in a variety of beverages (coffee, tea, and caffeinated soft drinks) and nu...
