Effects of dispersal and predation by Daphnia magna and dispersal on the assembly mechanisms and diversity patterns of bacterial metacommunities.
To investigate the interactive effect of D. magna (predation) and dispersal on the diversity and underlying assembly mechanisms of bacterial metacommunities. This was assessed by a microcosm experiment with artificial metacommunities consisting of three local communities (water from three different rock pools). Six different metacommunities were created by applying a 2-factorial design with 3 levels of dispersal among patches and presence or absence of D. magna.
