This book first reviews the biology of Dytiscidae or water beetles, including life history and ecology. It then defines and keys adults & larvae (when known) of dytiscid fauna of Canada, the United States, and for some taxa also northern Mexico. The focus is on the fauna of Canada & Alaska, and adults of the 276 species known from this region are treated in detail. For each Canadian-Alaskan species, the following information is presented: nomenclature & synonymy; selected references; description, including illustrations of taxonomically important characteristics; comments on classification or variation; notes on ecology; and description of the species range, accompanied by a map of collection records. Checklists of the dytiscid fauna of Canada/Alaska are also presented, with the distribution of the species recorded by province/territory and Canadian ecozone. Includes systematic index.

The 2nd edition of this comprehensive book provides one of the most complete overviews of the aquatic beetles in the family Dytiscidae, also known as predaceous diving beetles. Dytiscids constitute one of the largest families of freshwater insects with approximately 4,650 named species that come in a variety of sizes, colors, and habitat affinities. Although dytiscid adults and larvae are ubiquitous throughout a variety of aquatic habitats, and are important predators on other aquatic invertebrates and vertebrates, there are no compilations that have focused on summarizing the knowledge on aspects of their ecology, systematics, and biology. Chapters in this book summarize hitherto scattered topics, including their anatomy and habitats, chemical and community ecology, phylogenies and larval morphology including chaetotaxy, sexual systems, predation, dispersal, conservation, and cultural and historical aspects. The 2nd edition offers updates on the newest scientific findings on dytiscids and also includes a new chapter on the subterranean fauna from Australia. The information in this new edition is potentially beneficial to anyone working in aquatic systems where dytiscids are an important part of the food web. Moreover, readers will gain a greater appreciation of dytiscids as model organisms for investigations of fundamental principles derived from ecological and evolutionary theory. Contributed chapters are by authors who are actively engaged in studying dytiscids, and each chapter provides color photos and future directions for research.

Concerns about global biodiversity are rising dramatically, yet we are lagging behind in the most basic prerequisite for its understanding and conservation: the inventory. Insect species may make up five or ten times the number of all other plant and animal species combined, and as such they represent one of the major challenges in biosystematic science. World Catalogue of Insects is an initiative aiming at compiling worldscale, authoritative catalogues of monophyletic insect taxa. We are therefore proud to launch this major series. Volumes will as a minimum contain standard nomenclatoral information on all names pertaining to the taxon treated, including type locality and distribution to the extent this is relevant. Additional information is optional, e. g., location, status and condition of types; biology; bibliographical information; pest status; vector status; etc. This volume three focuses on Dytiscidae (Coleoptera).

A thorough update of Arnett's The Beetles of the United States, American Beetles, Volumes I and II cover the genera of beetles that occur in Alaska, Canada, and the contiguous United States. Built on the foundation of the original work and almost completely rewritten with contributions from more than 60 coleopterists, these volumes describe each fa

The first comprehensive book in more than a century to reveal the diversity and natural history of diving beetles. Among the hundreds of thousands of species of beetles, there is one family, containing some 4,300 species, that stands out as one of the most diverse and important groups of aquatic predatory insects. This is the Dytiscidae, whose species are commonly known as diving beetles. No comprehensive treatment of this group has been compiled in over 130 years, a period during which a great many changes in classification and a near quadrupling of known species has occurred. In Diving Beetles of the World, Kelly B. Miller and Johannes Bergsten provide the only full treatments of all 188 Dytiscid genera ever assembled. Entomologists, systematists, limnologists, ecologists, and others with an interest in aquatic systems or insect diversity will find these extensively illustrated keys and taxon accounts immensely helpful. The keys make it possible to identify all taxa from subfamily to genera, and each key and taxon treatment is accompanied by both photographs and detailed pen-and-ink drawings of diagnostic features. Every genus account covers body length, diagnostic characters, classification, species diversity, a review of known natural history, and world distribution. Each account is also accompanied by a range map and at least one high-resolution habitus image of a specimen. Diving beetles are fast becoming important models for aquatic ecology, world biogeography, population ecology, and animal sexual evolution and, with this book, the diversity of the group is finally accessible.

This book is a revised edition of the first of three volumes in the Handbook of Zoology series which treats the systematics and biology of Coleoptera. With over 380,000 described species, Coleoptera are by far the most species-rich order of insects and the largest group of animals of comparable geological age. Moreover, numerous species are tremendously important economically. The beetle volumes meet the demand of modern biologists seeking to answer questions about Coleoptera phylogeny, evolution, and ecology. This first Coleoptera volume covers the suborders Archostemata, Myxophaga and Adephaga, and the basal series of Polyphaga, with information on world distribution, biology, morphology of all life stages, phylogeny and comments on taxonomy.

New taxonomic, distribution and habitat data are presented for Canadian species in various families of Coleoptera. Distributional records are presented mostly from New Brunswick but also Quebec, Nova Scotia and Prince Edward Island. For New Brunswick, 320 new provincial records, 6 new records for Canada, and 22 new records of adventive species are provided. For Quebec, 1 new provincial record is provided; for Nova Scotia, 11 new provincial records are provided; and for Prince Edward Island, 2 new provincial records are provided. Maps of all new distribution records and significant new biological information are provided for all species. This volume on Maritime provinces beetle biodiversity contributes new and important baseline data, and significantly updates the known Coleoptera faunas of New Brunswick, Quebec, Nova Scotia, Prince Edward Island, and Canada.

ÿThis volume includes fourteen research articles on Canadian Coleoptera, mainly on the families Staphylinidae, Leiodidae, Histeridae, Nitidulidae, Cucujidae, Phalacridae, Silvanidae, Laemophloeidae, Tetratomidae, several aquatic groups, and others. An introductory editorial traces the history of scientific research and indicates areas of future inquiry. The papers address various questions with respect to the distribution, dispersal, zoogeographical status, phenology, and bionomics of Canadian Coleoptera, the role of saproxylic beetles in forest ecosystems, and invasive species in native habitats. The answers to these questions have important economic and environmental consequences. The book is addressed to coleopterists, ecologists, biogeographers, and conservationists.

This volume includes thirteen research articles focused primarily on Canadian Coleoptera. Several taxonomic and biodiversity studies examine groups within the Staphylinidae, Cerambycidae, Gyrinidae, and Haliplidae, describing new species, presenting keys to identification, mapping distributions, and reporting new provincial and national records. Other studies direct their attention to saproxylic beetles as indicators of forest disturbance, and to the beetle fauna of Rhode Island and the larger zoogeographic utility of distributional checklists. An introductory essay discusses a variety of challenges to biodiversity and biosystematics research worldwide. The contents of present volume represent stepping-stones of biodiversity research ? a discipline vital to the future of life on the planet. The book is addressed to coleopterists, taxonomists, ecologists, biogeographers and conservationists.
