It also examines and summarizes literature on the mitigation, rehabilitation and restoration of rivers affected by these human modifications. Data gaps in our current WebOur results indicate that river regulation that leads to channelization can reduce diversity and macroinvertebrate densities at the landscape scale by severing linkages between the aquatic and riparian communities. These effects appear especially acute for predaceous macroinvertebrates, perhaps because preferred prey density is lowered. major oak surgery edwinstowe
