In streambed sediments, the body-size distribution of protozoan and invertebrate species often relates to the size-spectrum of organic particles1. In those habitats, most meiobenthic species use flocs of organic particles, which are embedded in the interstices of the streambed sediments, as transitory habitat and as grazing ground.
We explored multifractality and lacunarity to quantify the complexity of streambed habitats using both field and laboratory experiments. We assessed the effects of habitat complexity on meiofaunal spatiotemporal distribution, movement and feeding processes in freshwater systems2,3.
