AB Acid Mine Drainage (AMD) results from sulfide oxidation, which incorporates hydrogenions, sulfate, and metals/metalloids into the aquatic environment, allowing fixation, bioaccumulationand biomagnification of pollutants in the aquatic food chain. Acidic leachates from waste rock damsfrom pyritic and (to a lesser extent) coal mining are the main foci of Acid Mine Drainage (AMD)production. WhenAMDis incorporated into rivers, notable changes in water hydro-geochemistry andbiota are observed. There is a high interest in the biodiversity of this type of extreme environments forseveral reasons. Studies indicate that extreme acid environments may reflect early Earth conditions,and are thus, suitable for astrobiological experiments as acidophilic microorganisms survive onthe sulfates and iron oxides in AMD-contaminated waters/sediments, an analogous environmentto Mars; other reasons are related to the biotechnological potential of extremophiles. In addition,AMD is responsible for decreasing the diversity and abundance of different taxa, as well as forselecting the most well-adapted species to these toxic conditions. Acidophilic and acidotoleranteukaryotic microorganisms are mostly composed by algae (diatoms and unicellular and filamentousalgae), protozoa, fungi and fungi-like protists, and unsegmented pseudocoelomata animals such asRotifera and micro-macroinvertebrates. In this work, a literature review summarizing the most recentstudies on eukaryotic organisms and micro-organisms in Acid Mine Drainage-affected environmentsis elaborated.
