| The department's scientists are taking samples of macroinvertebrates in small watercourses located mainly in the lower St. Lawrence region. |
| Moreover, there was a significant reduction in the loss of leaf material from coarse-mesh bags deployed at the downstream station, suggesting an inhibition of leaf decomposition by macroinvertebrates. |
| With over 100 families and 3000 species of macroinvertebrates in Canada, the cost of detailed taxonomy, which is necessary to provide maximum discriminatory power, is high. |
| The Yukon monitors fish and macroinvertebrates, and the International Polar Year program monitors for fish, chlorophyll a and macroinvertebrates. |
| The canoes gathered every 10 minutes so that groups could make presentations on topics like the creation of Shoelace Park, macroinvertebrates, and the birds and fish of the Bronx River. |
| These fairy shrimps and backswimmers constitute the majority of the macroinvertebrates captured in these ponds. |
