Among the various groups of aquatic insects, mayflies (Ephemeroptera) are of special interest for professional limnologists and entomological researchers as well as for naturalists in general and even the dedicated fly angler. Identification has traditionally been considered difficult and implementation in environmental monitoring and freshwater management has led to an ever increasing demand for exact information on taxonomy and ecology. The present handbook is designed to provide for the first time an up-to-date standard work for Ephemeroptera identification, including last instar larvae (nymphs), subimago (dun), male and female imagines. Recent changes in nomenclature are discussed in detail as well as gaps in current knowledge and probable pitfalls concerning the reliable identification of all taxa known so far from the region. Keys are provided for genera and introductory chapters characterize every family and genus. Species accounts follow a common format providing a synonymy, characters for identification (including literature references), remarks (on type material, variation, confusing or extralimital species) and short information on biology and distribution pattern. Male genitalia are illustrated by micrographs and line drawings, REM photographs of the egg chorionic structure are provided for genera and selected species. Habitus of larvae and imagines are for most genera illustrated by colour photographs. The geographical area covered is Europe including the European part of Russia, the mediterranean islands and North Africa. Short additional information is provided for adjacent parts of the western Palaearctic Region. A comprehensive index, check-list and distribution catalogue (following the widely adopted concept of Illies’ Limnofauna Europaean) allow for quick information on all species recorded so far from Europe.
Volume I For the fly fisher seeking to catch more and bigger trout, fishing nymphs--patterns that mimic the larval stage of mayflies--can be a surefire approach. Nymphs: The Mayflies, the first volume in a totally revised edition of the 1973 original, is the singular authority on identifying the myriad species of mayfly larvae and tying imitations that will attract trout all across the country. Author Ernest G. Schwiebert spent the last fifty years of his life traveling, fishing, and gathering information on scores of mayfly species across the country. The 1973 edition of Nymphs set forth his initial findings. Now in this wholly revised and expanded form, Schwiebert's last work offers the reader exacting details of every major mayfly species for the sake of identification, along with recipes for dozens of fly patterns to imitate them. This new edition also contains numerous stories and anecdotes from Schwiebert's travels, some never set down in writing before, that further add to the understanding of how to choose, cast, and fish nymphs, and life.
The papers included in this volume were presented at the VIth International Ephemeroptera Conference and the Xth International Symposium on Plecoptera, and at a Joint Symposium on Applied Aspects in the study of Mayflies and Stoneflies. One additional paper has been included, a review of the studies of on mayflies.
- Time-tested strategies for fishing tailwaters and matching the hatch season by season - The flies and knots for success - Including contributions by regional expertsTailwaters provide extraordinary year-round fishing, but you have to know how to fish them. The author covers how tailwaters work--how cold waters released from a dam affect the water, the aquatic life, and the fish. This book has it all: the hatches, the best imitation flies to use in every circumstance, nymphing and dry-fly tactics, all illustrated with drawings by artist Dave Hall and more than 200 color photographs.
The book has general biological significance due to usage of the new non-ranking nomenclature and the rational layout of taxonomic text, which can be qualified as post-Linnaean systematics. While after the works by Lameere and Hennig, non-ranking classifications became widely used, this book represents the first experience of consistently non-ranking classification, including taxa of low taxonomic level (i.e. taxa traditionally regarded as genera, families et al.). In contrast to other recent attempts to elaborate a non-ranking nomenclature not contradictory to the International Code of Zoological Nomenclature, this one appears to be successful and can be applied to any zoological taxa (although its application in botany could be possible only after further elaboration). Biology is currently going through a crisis, which causes some investigators to use such non-scientific methods of reconstructing phylogeny as parsimony analysis. The author believes that the new method of phylogeny description and reconstruction used in this book will help indicate a way out of this crisis.
