" ... Comprehensive, up-to-date information on the 21 species of wild terrestrial carnivores in the province."--Back cover.
Hoofed mammals (ungulates) are the most abundant large mammals in the world. They are also plentiful in British Columbia, which is home to nine wild native species: moose, elk, caribou, bison, mountain goat, two species of deer and two of sheep. There are also several introduced species. In Hoofed Mammals of British Columbia, David Shackleton presents a comprehensive summary of the most up-to-date information on these ungulates. In the well-illustrated introduction, he discusses their evolution and biology, survival adaptations, and social organization. He also covers conservation issues, tracking, and taxonomy. In the species accounts, he describes each species and subspecies and discusses their natural history: habitat, diet, behaviour, reproduction, life expectancy, and mortality factors, and predators. Each account includes a distribution map and data on taxonomy, recent population estimates, conservation status, and traditional aboriginal use. Excellent illustrations and two keys help identify each species by its external features or its skull. Hoofed Mammals of British Columbia is the third of six handbooks on the mammals of British Columbia, a Royal B.C. Museum project to update and expand the classic treatment by Ian McTaggart-Cowan and Charles Guiguet, The Mammals of British Columbia, last revised in 1965.
Rodents are the world's most numerous and diverse group of mammals. British Columbia is home to 45 species, from the tiny Western Harvest Mouse to the large and toothy Beaver, from the ubiquitous rats and squirrels to the endangered Vancouver Island Marmot. Just 7 species of lagomorphs inhabit BC: 5 rabbits and hares, and 2 pikas. Most people regard these small mammals as pests or vermin, but we cannot overlook their importance to the province's ecosystems. Because of their abundance, rodents and lagomorphs are vital prey species for raptors and mammalian carnivores. Burrowing species play an important role in aerating soils. Some rodents, such as chipmunks, voles and flying squirrels, are also important in forest ecosystems because they consume truffles or underground fungi and disperse their spores on the forest floor. In Lagomorphs and Rodents of British Columbia, David Nagorsen summarizes the most up-to-date information on these mammals. He discusses their general biology, including ecology, diet, anatomy, conservation and relations with humans. Illustrated keys aid in identification of the 52 species inhabiting the province. For each species, the author describes its natural history, identifying characteristics, taxonomy and conservation status in the province. Each species account is accompanied by illustrations and a distribution map.
Dr. John Ford presents the latest information on 31 species of marine mammals that live in or visit BC waters: 25 whales, dolphins and porpoises, 5 seals and sea lions, and the sea otter. He describes each species and summarizes its distribution, habitat, social organization, feeding habits, conservation status and much more. Marine Mammals of British Columbia includes maps of sightings, and pointers on where to find each species in BC waters. It also contains hundreds of colour photographs and drawings to help recognize these animals in the ocean. This is an indispensable field guide and reference book for naturalists, boaters and anyone interested in marine life.
Mammalogist David Nagorsen covers 12 species of insectivores (shrews and moles) and one marsupial (an opossum), describing their identifying characteristics, natural history, habitat and distribution. He also discusses the general biology of this group, including diet and anatomy.
Islands, with their simplified ecosystems and isolation from other populations in both space & time, provide natural settings for the study of numerous disciplines in relation to evolution. The Queen Charlotte Islands are some of the more isolated islands on the north-west coast of North America and are therefore of special interest in the study of the biotic evolution of this region. The purpose of this paper is to report on an analysis of the evolution of the native land mammals of these islands. An important aspect is to determine how much of the endemism present on the islands is accounted for by reason of its being a relict population or how much is a contribution of the insularity of the environment. The paper begins with a review of the Islands' setting and an assessment of the possibility of glacial refugia being present on the island. The Islands' physiography, vegetation, endemic species, the impoverished nature of the fauna encountered, and the probability of species survival in a refugium during the last glaciation are reviewed. The second section examines eight species of native mammals in an attempt to reconstruct their past history in a Queen Charlotte setting. The research is based on field studies conducted in 1960 & 1961 and examination of specimens collected & specimens in museums. Sources of variation, rates of evolution, and factors responsible for species appearance or disappearance are discussed. The final chapter reviews the evolution of mammals on other islands to show any trends which may be present in insular mammals.
