Rare Butterflies Of Southeastern Vancouver Island And The Gulf Islands The Disappearance Of Critical Food Plants Threatens This Region S Butterfly Diversity

Beautifully illustrated and clearly presented, The Butterflies of Canada is an indispensable guide to all aspects of butterfly study. Butterfly collecting has long been a popular summer activity, and as the growing popularity of butterfly watching and conservatories in Ontario and British Columbia shows, butterflies are a continuing source of delight and interest to Canadians. The Butterflies of Canada is the first comprehensive guide to all the butterflies found in Canada. Based on the national butterfly collection maintained by Agriculture and Agri-Food Canada, it contains descriptive individual accounts for the close to three hundred butterfly species recorded in Canada, including descriptions of early stages, subspecies, and key features that help distinguish similar species. Each species of butterfly has an individual distribution map, generated from a database of more than 90,000 location records. More than just a field guide to identifying Canadian butterflies, however, The Butterflies of Canada includes chapters on Canadian geography and butterfly distribution, conservation, gardening, photography, and the history of butterfly study in Canada. It also contains new and unpublished information on the classification of butterflies, their ranges, larval food plants, abundance, flight seasons, and noteworthy habits. Thirty two colour plates provide diagnostic details for each species, and also feature butterflies in their natural habitats. There is an extensive bibliography.

"Australia's unique biodiversity is under threat from a rapidly changing climate. The effects of climate change are already discernible at all levels of biodiversity - genes, species, communities and ecosystems. Many of Australia's most valued and iconic natural areas - the Great Barrier Reef, south-western Australia, the Kakadu wetlands and the Australian Alps - are among the most vulnerable. But much more is at stake than saving iconic species or ecosystems. Australia's biodiversity is fundamental to the country's national identity, economy and quality of life. In the face of uncertainty about specific climate scenarios, ecological and management principles provide a sound basis for maximising opportunities for species to adapt, communities to reorganise and ecosystems to transform while maintaining basic functions critical to human society. This innovative approach to biodiversity conservation under a changing climate leads to new challenges for management, policy development and institutional design. This book explores these challenges, building on a detailed analysis of the interactions between a changing climate and Australia's rich but threatened biodiversity. Australia's Biodiversity and Climate Change is an important reference for policy makers, researchers, educators, students, journalists, environmental and conservation NGOs, NRM managers, and private landholders with an interest in biodiversity conservation in a rapidly changing world."--Publisher.

Biodiversity is the extraordinary variety of life on Earth -- from genes & species to ecosystems & the valuable functions they perform. Life as we know it will not be the same if our rich biodiversity heritage is dramatically altered. And the signs indicate that this is precisely what is happening. Biodiversity is threatened, & not because of catastrophic events. The current threat to biodiversity, & thus to the tapestry of life, stems primarily from expanding human populations & increased human consumption of natural resources. Fortunately, we can take steps to protect our rich biodiversity. This report explains what biodiversity is, why it is so important, why it is threatened, & what can be done to conserve this valuable resource. Illustrations.
