Does the predatory rotifer Asplanchnainduce a behavioral response in the prey rotifer Brachionus calyciflorus?
Abstract The planktonic rotifer Brachionus calyciflorus was reported to have a behavioral response to the predatory rotifer Asplanchna, where individuals move up to a surface-film refuge. Here, I re-examine this response and also test the hypothesis that Asplanchna affects the propensity of B. calyc...
