Macroinvertebrates in stream systems

In summary, Macroinvertebrates are small organisms that lack a backbone and are visible to the naked eye. They play a crucial role in stream ecosystems by serving as food for larger organisms, helping with decomposition and nutrient cycling, and indicating the health of the stream. Scientists use various methods to collect and study macroinvertebrates, such as kick-net sampling and visual observations. The presence or absence of certain macroinvertebrates can indicate the overall health of a stream, providing valuable information for stream management and conservation efforts.

Hey pf! Learning about macroinvertebrates and their relation to stream systems, and I am trying to understand what stream factors affect their distribution and diversity! I understand that flow rate, and substrate for example have an affect, but why exactly flow rate affects macro's is still a mystery to me! Are there any entomologists in the house?

Thanks,
Sastronaut
