Assessment of Large River Benthic Macroinvertebrate Assemblages
 |
|
| Abstract: | During the summer of 2001, twelve sites were sampled for macroinvertebrates, six each on the Great Miami and Kentucky Rivers. Sites were chosen in each river from those sampled in the 1999 methods comparison study to reflect a disturbance gradient. At each site, a total distance equal to 40 times the mean wetted width was sampled at specific intervals. Timed kick net and dip/pick samples were combined into a single sample for each transect and bank. The relationship of distance sampled with metrics and species composition, as well as variability among transects and between banks, will be analyzed to determine the most efficient sampling design for these rivers. |
