OSTI ID:5554780
Acellus aquaticus inhabits pristine oligotrophic and dystrophic lakes, as well as eutrophic sites influenced by agriculture or organic pollution. Total hardness in lakes with A. aquaticus was 0.23 -20.80 degrees dh (1 degrees dh = 10 mg ''CaO''/1) and pH 4.8 -8.8. Slow immigration and cold climate (above 1050 m altitude) restrict the distribution of the species. Acidification has occurred in lakes containing A. Aquaticus. It threatens existing populations and restricts the number of potentially new habitats for future immigration.
