The best-selling Field Guide to Freshwater Fishes of Ontario is back as a second edition. It is a beautiful and authoritative full-colour field guide to all species of freshwater fish found in Ontario.
Field guide of Freshwater fish.
"By the end of this Primer, you will: understand the federal and Ontario legislation and regulations pertinent to the use of baitfishes; be able to identify small fish species; be able to distinguish between legal and illegal baitfishes; recognize the importance of baitfish habitat; understand the potential impacts of improper baitfish use; and, understand how to minimize negative impacts to our aquatic ecosystems"--Introduction, page 4.
A chronicle of the passing seasons in Central and Eastern Ontario designed to inform cottagers, gardeners, photographers, suburban backyard birders, and nature enthusiasts alike as to the natural events that can be expected each month of the year.
Ontario's diverse mammal population is beautifully portrayed in this comprehensive and easy-to-use field guide. Colour-coded header bars organize the mammals into seven major groups. Large, full-colour photographs are complemented by colour illustrations, detailed drawings of prints and tracks and range maps. All species are indexed in an illustrated quick reference guide. The text includes detailed descriptions of habitat, food, young, den, range and similar species, as well as fun facts about each animal's natural history and behaviour.
This illustrated field guide helps readers identify, understand and appreciate the birds of Ontario. It contains full-colour illustrations and detailed descriptions of 318 species, with each account including information on: *Size * Status * Habitat * Nesting * Feeding * Voice * Similar species cross-referenced * Best sites for viewing * Range maps showing seasonal occurrences of the bird and migration routes. * Colour-coded header bars and a quick reference guide make finding information fast and easy. Also includes a glossary of terms and a birder's checklist. Technical review by Ross James, former Curator of Ornithology at the Royal Ontario Museum.
The second edition of The Diversity of Fishes represents a major revision of the world’s most widely adopted ichthyology textbook. Expanded and updated, the second edition is illustrated throughout with striking color photographs depicting the spectacular evolutionary adaptations of the most ecologically and taxonomically diverse vertebrate group. The text incorporates the latest advances in the biology of fishes, covering taxonomy, anatomy, physiology, biogeography, ecology, and behavior. A new chapter on genetics and molecular ecology of fishes has been added, and conservation is emphasized throughout. Hundreds of new and redrawn illustrations augment readable text, and every chapter has been revised to reflect the discoveries and greater understanding achieved during the past decade. Written by a team of internationally-recognized authorities, the first edition of The Diversity of Fishes was received with enthusiasm and praise, and incorporated into ichthyology and fish biology classes around the globe, at both undergraduate and postgraduate levels. The second edition is a substantial update of an already classic reference and text.

The young field of invasion biology - initially a branch of ecology and conservation biology - has greatly expanded, particularly in the last two and a half decades or so. As a result, the potential negative effects of introduced species have been widely advertised and sometimes, perhaps, overemphasized. This book attempts to restore some balance to the current debate over the role of non-native species, by offering a broader perspective, and taking a longer term, evolutionary look at these species and their impact in their new environments. The relatively arbitrary nature of terms such as "native" and "non-native", and the rather inconsistent ways in which such terms are applied to biological species, as well as the subjective boundaries of so-called "native ranges" are analyzed. The role of non-native species in their new environments can be considerably more complex than the anti-introduced species information would often suggest. Thus, the more positive and nuanced perspective on introduced species and their impact offered in this book is much needed and long overdue.
