Diving Beetles Of The World

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.

Predaceous diving beetles (Coleoptera: Dytiscidae) constitute one of the largest families of freshwater insects (~ 4,200 species). Although dytiscid adults and larvae are ubiquitous throughout a variety of aquatic habitats and are significant predators on other aquatic invertebrates and vertebrates, there are no compilations that have focused on summarizing the knowledge of their ecology, systematics, and biology. Such knowledge would benefit anyone working in aquatic systems where dytiscids are an important part of the food web. Moreover, this work will allow 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 offers a synthesis of the current knowledge of a variety of topics and will provide future directions for research.

Winner, 2018 Amazon Canada First Novel Award, 2018 McNally Robinson Book of the Year, and 2018 Margaret Laurence Award for Fiction Shortlisted, 2017 Governor General's Award for Fiction and 2018 Eileen McTavish Sykes Award for Best First Book A National Post Best Book of 2017 A Walter Scott Prize Academy Recommended Historical Novel of 2017 On CBC Books' list of writers to watch in 2018 The Leung family leads a life of secluded luxury in Hong Kong. But in December 1941, the Empire of Japan invades the colony. The family is quickly dragged into a spiral of violence, repression, and starvation. To survive, they entomb themselves and their friends in the Leung mansion. But this is only a temporary reprieve, and the Leungs are forced to send their children away. The youngest boy, Chung-Man, escapes with some of his siblings, and together they travel deep into the countryside to avoid the Japanese invaders. Thrown into a new world, Chung-Man befriends a young couple who yearn to break free of their rural life. But their friendship ends when the Japanese arrive, and Chung-Man is once again taken captive. Unwittingly and willingly, he enters a new cycle of violence and punishment, until he finally breaks free from his captors and returns to Hong Kong. Deeply scarred, Chung-Man drifts along respectfully and dutifully, enveloped by the unspoken vestiges of war. It is only as he leaves home once again -- this time for university in America -- that he finally glimpses a way to keep living with his troubled and divided self. Written in restrained, yet beautiful and affecting prose, The Water Beetles is an engrossing story of adventure and survival. Based loosely on the diaries and stories of the author's father, this mesmerizing story captures the horror of war, through the eyes of a child, with unsettling and unerring grace.

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.

Check out the action at a nearby pond where a master predator is on the hunt a diving beetle! This skillful insect is after larvae, small fish, salamanders, and other prey. Key body parts make a diving beetle an effective hunter. When it spots a target, the beetle's body traps an air bubble, which it uses to breathe underwater for up to 10 to 15 minutes! Its legs act like oars to move it quickly through the water. A smooth, waxy coat helps too. The diving beetle snatches its prey with its strong jaws. Bite by bite, the adult beetle devours its meal. In this exciting book, you can learn what makes diving beetles similar to and different from other insects. Close-up photographs and diagrams reveal extraordinary details about diving beetle bodies, both inside and out. And you can perform activities that help you find ways protect the diving beetles watery home, and understand how diving beetles breathe underwater. Learn more about this exiting member of nature's fascinating Insect World!

“Profiles 600 of the most stunning, most wonderfully adapted beetles around . . . The result is a work that is nothing short of magnificent.” —Wired When renowned British geneticist J. B. S. Haldane was asked what could be inferred about God from a study of his works, Haldane replied, “An inordinate fondness for beetles.” With 350,000 known species, and scientific estimates that millions more have yet to be identified, their abundance is indisputable as is their variety. They range from the delightful summer firefly to the one-hundred-gram Goliath beetle. Beetles offer a dazzling array of shapes, sizes, and colors that entice scientists and collectors across the globe. The Book of Beetles celebrates the beauty and diversity of this marvelous insect. Six hundred significant beetle species are covered, with each entry featuring a distribution map, basic biology, conservation status, and information on cultural and economic significance. Full-color photos show the beetles both at their actual size and enlarged to show details, such as the sextet of spots that distinguish the six-spotted tiger beetle or the jagged ridges of the giant-jawed sawyer beetle. Based in the most up-to-date science and accessibly written, the descriptive text will appeal to researchers and armchair coleopterists alike. The humble beetle continues to grow in popularity, taking center stage in biodiversity studies, sustainable agriculture programs, and even the dining rooms of adventurous and eco-conscious chefs. The Book of Beetles is certain to become the authoritative reference on these remarkably adaptable and beautiful creatures. “Photographs of more than 600 colorful, glossy species, resembling bejeweled broaches morethan creepy crawlies, are presented at actual size.” —Publishers Weekly
