Macroinvertebrate species occupancy frequency distribution patterns in eutrophic lakes

Abstract Metacommunity models describe species occupancy frequency distribution (hereinafter ‘SOFD’). Our goal is to present how the differences in eight macroinvertebrate orders dispersal ability affect SOFD patterns. A total of 293 from were observed 14 eutrophic lakes southern Finland. Species ranged 1 14. About 30% (89 out 293) found only one lake, yielding a surprisingly high number rare species. So, there few widely distributed common and numerous with restricted distribution. Combined data supported bimodal truncated pattern. Similarly, low orders, watermites mayflies, fitted However, symmetric pattern also relatively well dragonflies damselflies ability. It seems that among different may partly explain differences. Moreover, our results slightly more niche-based model rather than metapopulation dynamics littoral metacommunities. highlight important trait for conservation patchily habitat.
