5.0 out of 5 stars A Guide to the Study of Fresh-Water Biology
A genuine classic used heavily by my students in ecology in several decades of teaching. A detailed glossary is usually sufficient to enable beginners to readily use the keys to identify the most readily observed and collected fresh-water plants and animals.

3.0 out of 5 stars Creatures in the River
A small book, packed with drawings, scientific references and keys on river biota. It's a bit old, 1962. Challenges you to get out there and do your own collecting and tells you what equipment to have. I was hoping for more description on the ecology of rivers, i.e. who eats who. But any lack there is mine, for not reading more carefully.

This review is from: Guide to the Study of Freshwater Biology (Paperback)
A genuine classic used heavily by my students in ecology in several decades of teaching. A detailed glossary is usually sufficient to enable beginners to readily use the keys to identify the most readily observed and collected fresh-water plants and animals. With keys for the identification of all major groups of aquatic life from algae, major invertebrates and common fishes, this compact volume is a delight. In addition, representatives most commonly seen by students are illustrated with accurate, well-labelled line drawings. A brief essay on methods of sampling and analyzing aquatic organisms and their habitats completes this compact, useful guide. To be sure, the references, although significant in their day, are now of historical interest and more interested students and others eager to learn more about aquatic life would need to do some library search for more current work on the aquatic organims featured in this guide.
