Benthic macroinvertebrate community structure in streams of different salinities

摘要: The likely effect of salinization on stream invertebrates was studied by comparing macroinvertebrate community structure at nine sites in six lowland, perennially flowing streams. salinity these streams ranged from 51 to 1100 mg L-1 total dissolved solids (TDS) (and were historically higher, up about 2000 TDS). There no correlation between either number taxa or faunal abundance with salinity. However, multivariate analyses showed distinct invertebrate communities associated different salinities. Fidelity analysis identified groups low high Existing information the distribution common within indicated that they tolerant wider ranges than those found this study. rare most clearly distinguished salinities and are possibly more sensitive changes
