Fig. A1. Schematic diagram of pond mesocosm metacommunities under no, low, and high planktonic dispersal. Each metacommunity replicate consisted of three mesocosm communities, where two communities differed in the incidence of bluegill sunfish (Lepomis macrochirus) and the third community maintained pulsed predation from bluegill. (a) Metacommunity replicate design for the no dispersal and low dispersal treatments. To simulate low planktonic dispersal (0.7%/d), water was manually transferred among the three communities. A water pump and a polyvinyl chloride (PVC) loop in each community controlled for both in the high dispersal treatment. (b) Metacommunity replicate design for the high dispersal treatment. To simulate high planktonic dispersal (20%/d), water was transferred among the three communities with a pump and PVC pipe. Adapted from Howeth and Leibold (2010).
