Book Description
Wetlands are crucial ecosystems that help filter a great number of toxicants out of the earth's waters. They must be managed and occasionally even built from scratch, including all of the flora and fauna that grows there. Invertebrates play a key role in the wetland food chain. This comprehensive resource is the first dedicated solely to the ecology and management of invertebrates.
