Biosystematic Revision Of The Genus Stenonema Ephemeroptera Heptageniidae

A revision of the genus Stenonema Traver, based on a study of variability in species range and the application of a biological definition of species. Characteristics and terminology are reviewed, systematic accounts and keys listed, evolutionary biology discussed for Stenonema mayflies in streams and rivers west and east of the Mississippi.

This volume is the proceedings of the IX International Conference on Ephemeroptera and the XII International Symposium on Plecoptera, held in Tucuman, Argentina. Divided into comprehensive thematic sections, the early sections cover studies on ecology and behavior ranging from life cycles and general biology to genetic divergence and vibrational communication, while the latter sections reveal the diversified studies being developed worldwide. This book will be useful for beginners and specialists, providing important data for ecological, distributional, morphological, and biogeographical studies.

After teaming up to fish every major trout stream in the United States, Mecka and Hoover describe the fishing, hatches, and special regulations for each. Contents: Introduction; Insect Emegence; A Closer Look at Some of the Great Hatches; Great Rivers of the East and their Hatches; Great Rivers of the Midwest and their Hatches; Great Rivers of the West and their Hatches; Great Hatches on Lousy Days; Patters for the Hatches; Some Proposals for Better Fishing.

Completely updated guide to all of the hatches in trout streams and still waters in the Upper Midwest.

Written in language that is accessible to the sports fisherman and the naturalist and with over 1,000 original illustrations, the book includes features such as coverage of all insect families and genera important to fly fishing; comphrensive treatment of the biology of all life stages of aquatic insects including terrestrial as well as aquatic stages; special chapters on shore dwelling insects, insects associated with aquatic vascular plants, residents of tree holes and plant cups, aquatic arachnids and freshwater crustaceans.
