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.
An unforgettable coming-of-age novel that becomes a profound mediation on life, death, and lifelong friendship. Everyone has a Tully Dawson: the friend who defines your life. In the summer of 1986, in a small Scottish town, James and Tully ignite a brilliant friendship based on music, films and the rebel spirit. With school over and the locked world of their fathers before them, they rush towards the climax of their youth: a magical weekend in Manchester, the epicentre of everything that inspires them in working-class Britain. There, against the greatest soundtrack ever recorded, a vow is made: to go at life differently. Thirty years on, half a life away, the phone rings. Tully has news--news that forces the life-long friends to confront their own mortality head-on. What follows is an incredibly moving examination of the responsibilities and obligations we have to those we love. Mayflies is at once a finely-tuned drama about the delicacy and impermanence of human connection and an urgent inquiry into some of the most important questions of all: Who are we? What do we owe to our friends? And what does it mean to love another person amidst tragedy?
The Mayflies of North and Central America was first published in 1976. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. Mayflies have fascinated man for centuries because of the brief span of their adult lives. These aquatic insects spend most of their lives as nymphs in water, then develop into winged stages and soon die, most species having an adult life of only two or three days. This brevity is implied in the very name of the order, Ephemeroptera. The mayflies are almost worldwide in distribution, being found everywhere except in Antarctica, the extreme Arctic, and many small oceanic islands. All by three of the twenty families in the world occur in North or Central America, the regions covered in this volume. The book provides a modern, useful, and well-illustrated key to the adults and nymphs. Data on habitats, behavior, and life history are given for each genus. Characteristics of nymphs and adults are given for families, subfamilies, and genera, with brief accounts for extralimital families. A discussion of methods of collecting and preserving specimens precedes the main portion of the text. The book is generously illustrated with drawings, photographs, and a map. The role of aquatic insects as indicators of water pollution has received increasing attention, and in this connection this book will be of special interest to those concerned with pollution problems. Mayflies, besides indicating the presence of pollutants, also help remove such substances from the waters, the authors explain. As a basic reference work, the book is essential for all biological science libraries. Many fly-fishermen are amateur students of mayflies, since the nymphs of larger species are used as bait. With the help of this volume the fisherman can acquire a greater knowledge of aquatic entomology and relate to his sport.

Readers familiar with the first three editions of Ecology and Classification of North American Freshwater Invertebrates (edited by J.H. Thorp and A.P. Covich) will welcome the comprehensive revision and expansion of that trusted professional reference manual and educational textbook from a single North American tome into a developing multi-volume series covering inland water invertebrates of the world. The series entitled Thorp and Covich's Freshwater Invertebrates (edited by J.H. Thorp) begins with the current Volume I: Ecology and General Biology (edited by J.H. Thorp and D.C. Rogers), which is designed as a companion volume for the remaining books in the series. Those following volumes provide taxonomic coverage for specific zoogeographic regions of the world, starting with Keys to Nearctic Fauna (Vol. II) and Keys to Palaearctic Fauna (Vol. III). Volume I maintains the ecological and general biological focus of the previous editions but now expands coverage globally in all chapters, includes more taxonomic groups (e.g., chapters on individual insect orders), and covers additional functional topics such as invasive species, economic impacts, and functional ecology. As in previous editions, the 4th edition of Ecology and Classification of North American Freshwater Invertebrates is designed for use by professionals in universities, government agencies, and private companies as well as by undergraduate and graduate students. - Global coverage of aquatic invertebrate ecology - Discussions on invertebrate ecology, phylogeny, and general biology written by international experts for each group - Separate chapters on invasive species and economic impacts and uses of invertebrates - Eight additional chapters on insect orders and a chapter on freshwater millipedes - Four new chapters on collecting and culturing techniques, ecology of invasive species, economic impacts, and ecological function of invertebrates - Overall expansion of ecology and general biology and a shift of the even more detailed taxonomic keys to other volumes in the projected 9-volume series - Identification keys to lower taxonomic levels
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.

A man is unwillingly transformed into the sentient command core of a starship on a thousand-year journey—with thousands of passengers at his mercy . . . Transient. Ethereal. Delicate. Insignificant. Mere insects . . . Like all the human beings trapped aboard a vast starship on a generations-long journey to a new home. The Mayflower is run by an immortal captain who views himself as a god. Gerard Metaclura was just a normal man until a terrible accident left him near dead, his body destroyed. But his brain was installed as the sentient command core of the generation ship. At first Gerard was confused by what happened to him. Then angry. Then bored. Now he is the ship, controlling everything . . . including 25,000 helpless human passengers. Mayflies. But maybe they’re not willing to be so helpless and insignificant after all . . .
From the publisher. This beautifully illustrated book provides an overview of the world of insects. The encyclopedia of insect species is organized according to geographical region and then by insect order.
