The ordination of aquatic nematode communities as affected by stream water quality


, : The ordination of aquatic nematode communities as affected by stream water quality. Environmental biomonitoring, assessment, prediction, and management certain case studies and related quantitative issues: 101-116

Benthic nematodes were sampled at 16 sites on 2 streams in Indiana, USA, to investigate the relationships of nematode community structure to various water quality factors. Nematode densities were related to nutrient status and particle size of the benthic substrate, lowest densities occurring with the lowest level of nutrients, highest level of dissolved O2 and with large median particle size.

Few studies have reported the effects of gastrin-releasing peptide (GRP)/bombesin on the guinea pig gallbladder, and the results are contradictory. Because such contradictory results may, in part, be due to technical factors, we investigated the e...
