This book is a field guide to the commonly encountered freshwater macroinvertebrates of southern Africa. It highlights the incredible variation and beauty of freshwater macroinvertebrates, which play a critical role in freshwater and terrestrial ecosystems. The threat to these organisms is great as their habitats are increasingly threatened, either directly by human activities such as mining and agriculture, or by fluctuating water temperatures due to climate change. Christian Fry hopes that this book will create a greater understanding and interest in these tiny creatures and that there will be better care, enthusiasm and conservation of them.
