Abstract
A species list of macroscopic animals is compiled for the middle portion of the Little Sioux River, Iowa. These are tabulated along with published data from regions of the river above and below. The Little Sioux meanders throughout a valley of largely agricultural landscape; it has a relatively high silt load. Chemical differences are not great; some effects of municipal effluent are noted. The number of species is relatively constant (in the 40-60 range); numbers in the uppermost, intermittent stretches and the lowermost, channelized segment are lower (30- 40). Only about 20% of the species are ubiquitous; trends of diversity and distribution are noted in the invertebrates and fishes.
