This paper evaluates changes in the β-temporal diversity and species composition of aquatic Oligochaeta in an impacted urban river stretch. We show that changes in abiotic conditions might cause differences in species composition between years, leading to a reduction in β-temporal diversity. Thus, our results support the idea that Oligochaeta are indicators of environmental variations.
