Abstract

The impacts of stream disturbance caused by pleasured boat, and differences in seasonality on benthic macroinvertebrate communities, were evaluated in Lijiang River, China, October 2009 and April 2010. The environmental characteristic differed significantly between affected conditions and unaffected conditions. In wet period, the water temperature, conductivity and salinity after disturbance was significantly (p
