DOWNLOAD EBOOKAnnotation 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.

DOWNLOAD EBOOKWith 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.

DOWNLOAD EBOOKBeginning 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.

DOWNLOAD EBOOKTiger 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.

DOWNLOAD EBOOKA critically acclaimed nature writer explores the citizen scientist movement through the lens of entomological field research in the American Southwest. Award-winning nature writer Sharman Apt Russell felt pressed by the current environmental crisis to pick up her pen yet again. Encouraged by the phenomenon of citizen science, she decided to turn her attention to the Western red-bellied tiger beetle, an insect found widely around the world and near her home in the Gila River Valley of New Mexico. In a lyrical, often humorous voice, Russell shares her journey across a wild, rural landscape tracking this little-known species, an insect she calls “charismatic,” “elegant,” and “fierce.” What she finds is renewed optimism in mysteries still left to be explored, that despite the challenges of climate change, there is a growing diversity of ways ordinary people can contribute to the research needs of scientists today in the name of environmental activism. Offering readers a glimpse into the pioneering field of citizen science, Diary of a Citizen Scientist documents one woman’s transformation from a feeling of powerlessness to engaged hopefulness.

DOWNLOAD EBOOKThe 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.
