Two ecotypes of Asellus aquaticus were collected from two Swedish lakes: Lake Tåkern and Lake Fardume. Reed ecotype was collected from Phragmites australis (reed) habitat and chara ecotype was collected from adjecent Chara spp. (stonewort) habitat
The experimental design consisted of 2-L aquaria, each providing alder leaves (Alnus glutinosa), oak leaves (Quercus roburleaves) and periphyton as food sources.
Six treatments were applied for each lake in 3- categories:
1) Single ecotype in low density (6 indv.)
2) Single ecotype in high density (18 indv.)
3) A combination of one ecotype and Gammarus pulex (6 indv. from each)
Functional role such as decomposition and impact on algae biomass was examined for two ecotypes from both lakes.
