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.

Tiger beetles are one of the most obvious and ubiquitous families of any insect taxon--some 2300 species are found on nearly all the land surfaces of the earth. Their frequently showy colors, brazen behavior, and ability to live in habitats ranging from dry, alkaline lakebeds to tropical rain forests have captured the interest of amateur and professional entomologists alike. Although tiger beetles have been widely studied, the wealth of knowledge has been synthesized only briefly in a few sources.In Tiger Beetles, David L. Pearson and Alfried P. Vogler provide for the first time a detailed integration and summary of all that is known about the family Cicindelidae. The book's early chapters cover anatomy, distribution, and natural history. Pearson and Vogler build from these basics to show the usefulness of tiger beetles for exploring questions in genetics, biogeography, ecology, behavior, and conservation. As bioindicators, the tiger beetles present in an area may allow biologists to pinpoint places with the richest diversity of animal and plant life. The use of tiger beetles as model organisms has made possible or greatly enhanced many areas of research, including molecular phylogeny, the function of acute hearing, spatial modeling, and physiology of vision.
