Among beetles, tiger beetles are some of the favourites of nature-loving people. Large, active, and colourful, tiger beetles are as watchable as birds, and easily as fascinating. Well-loved naturalist John Acorn offers a fun and fascinating look at some of Alberta's smaller citizens.
A color-illustrated field and natural history guide that treats 107 tiger beetle species found in North America above the Mexican border. This work includes biological accounts that emphasize points for identification, behavior, and habitat. Distribution maps show where various species and subspecies can be found.
Annotation Since the 1960s, American and Canadian fisheries have been introducing salmonines such as rainbow trout and chinook and coho salmon to the Great Lakes in order to develop new recreational fisheries. In this study, Crawford (ichthyology, U. of Guelph) examines the effects of non-native fish populations on the Great Lakes ecosystem. He contends that the ongoing introduction of non-native salmonines poses an ecologically- significant risk and that the practice should be terminated. The volume is not indexed.

With iridescent blues and greens, damselflies are some of the most beautiful flying insects as well as the most primitive. As members of the insect order Odonata they are related to dragonflies but are classified in a separate suborder. These aquatic insects are a delight to the eye and a fascinating creature of study. In Damselflies of Alberta, naturalist John Acorn describes the twenty-two species native to the province. Exhaustively researched, yet written in an accessible style, the author's enthusiasm for these flying neon toothpicks is compelling. More than a field guide, this is a passionate investigation into one of nature's winged marvels of the wetlands.
Beginning in the late 1980s, a series of improbable bark beetle outbreaks unsettled iconic forests and communities across western North America. An insect the size of a rice kernel eventually killed more than 30 billion pine and spruce trees from Alaska to New Mexico. Often appearing in masses larger than schools of killer whales, the beetles engineered one of the world's greatest forest die-offs since the deforestation of Europe by peasants between the eleventh and thirteenth centuries. The beetle didn't act alone. Misguided science, out-of-control logging, bad public policy, and a hundred years of fire suppression created a volatile geography that released the world's oldest forest manager from all natural constraints. Like most human empires, the beetles exploded wildly and then crashed, leaving in their wake grieving landowners, humbled scientists, hungry animals, and altered watersheds. Although climate change triggered this complex event, human arrogance assuredly set the table. With little warning, an ancient insect pointedly exposed the frailty of seemingly stable manmade landscapes. Drawing on first-hand accounts from entomologists, botanists, foresters, and rural residents, award-winning journalist Andrew Nikiforuk, investigates this unprecedented beetle plague, its startling implications, and the lessons it holds.
Beetles are the largest and most studied order of insects, some of which are beneficial as biological control agents. Alphabetically lists all species and subspecies of beetles known to Canada and Alaska under their respective genus-group names. Includes a brief introduction for every family treated and an index to all supraspecific names.
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 catalogue explores the interrelationship between the science of entomology and the art of illustration by highlighting some of the key holdings of early and classic works on insects in the University of Alberta Library. George E. Ball demonstrates how advances in printing technologies from the sixteenth to the nineteenth centuries contributed to the developing body of entomological knowledge. Foreword by Merrill Distad.
John Rae is best known today as the first European to reveal the fate of the Franklin Expedition, yet the range of Rae’s accomplishments is much greater. Over five expeditions, Rae mapped some 1,550 miles (2,494 kilometres) of Arctic coastline; he is undoubtedly one of the Arctic’s greatest explorers, yet today his significance is all but lost. John Rae, Arctic Explorer is an annotated version of Rae’s unfinished autobiography. William Barr has extended Rae’s previously unpublished manuscript and completed his story based on Rae’s reports and correspondence—including reaction to his revelations about the Franklin Expedition. Barr’s meticulously researched, long overdue presentation of Rae’s life and legacy is an immensely valuable addition to the literature of Arctic exploration.
This issue of Journal of Insect Conservation is the first to be dedicated entirely to beetles. It contains a number of papers to demonstrate the variety and scope of problems and conservation concerns that surround these insects. A short introductory perspective is followed by eight original contributions, in which beetles from many parts of the world are considered, and in which some major threats to their wellbeing are evaluated.
