Composition of diets selected by tame but free-ranging deer in a natural forest environment was studied throughout a 24-month period and summarized by mean monthly percentage composition on the basis of dry-matter intake. A modification of the standard bite-count method of diet determination was used. All forages were identified by species and plant part (leaf, twig). Major forages comprising the diet were identified seasonally and considered in relation to their role in the nutritional ecology of the deer. Overall, a simple but consistent pattern was evident in the data. When green, leafy forages (herbs and shrub leaves) were available, they were consistently targeted by the foraging deer, but as they became less available in winter, and especially with their burial by snow, diet composition shifted to less digestible woody forages (shrub twigs and conifer foliage) supplemented with highly digestible arboreal lichens. Although a wide array of potential forages are available during the growing season, dietary options shrink to a narrow range of important evergreen forbs, a few ferns, shrub twigs, and lichens in winter.

This book brings together information on the natural history, ecology and systematics of North American aquatic monocotyledons. The book is an overview of the biology of major aquatic species by compiling information from numerous sources that lie scattered among the primary literature, herbarium databases, and other reference sources. Information on more than 300 species in 87 genera of monocotyledons will be included. Recent phylogenetic analyses will be incorporated. Although focusing specifically on North America, the cosmopolitan distribution of many aquatic plants should make this an attractive text to people working virtually anywhere outside of the region as well. Key Selling Features: The primary source of natural history information on aquatic plants Comprehensive lists of ecological associates Synthetic overview of systematic relationships of aquatic species and genera Practical information for rare and invasive plant managers Essential guide to facilitate wetland delineation

In A Shape in the Dark, wilderness guide and lifelong Alaskan Bjorn Dihle weaves personal experience with historical and contemporary accounts to explore the world of brown bears--from encounters with the Lewis and Clark Expedition, frightening attacks including the famed death of Timothy Treadwell, the controversies related to bear hunting, the animal’s place in native cultures, and the impacts on the species from habitat degradation and climate change. Much more than a report on human-bear interactions, this compelling story intimately explores our relationship with one of the world’s most powerful predators. An authentic and thoughtful work, it blends outdoor adventure, history, and elements of memoir to present a mesmerizing portrait of Alaska’s brown bears and grizzlies, informed by the species’ larger history and their fragile future.

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.
