Lower Trophic Levels and Aquatic Macrophytes
Changes in the abundance and community composition of primary and secondary producers can signal environmental impacts that would otherwise not be immediately obvious. For example, lower trophic level organisms can be used as bio-indicators of changing water levels and flows, or increased levels of suspended sediments and sedimentation. NSC employs biologists who are Canadian Aquatic Biomonitoring Network (CABIN) certified Project Managers that have developed sampling programs for phytoplankton, periphyton, aquatic macrophyte, zooplankton, and aquatic macroinvertebrate communities in waterbodies ranging from small streams to large rivers and lakes and marine environments.
