A Condition Guide For Aspen Ranges Of Utah Nevada Southern Idaho And Western Wyoming Classic Reprint

Excerpt from A Condition Guide for Aspen Ranges of Utah, Nevada, Southern Idaho, and Western Wyoming Aspen stands vary widely in size. They may occur as islands of trees separated by openings of varying size, or as a more or less contin uous forest. The term, aspen type, as used in this publication refers to all these areas. It includes not only the areas overshadowed by aspen, but also the openings in the aspen forest. It does not include areas of aspen mixed with more than 50 percent of conifer trees, however, or more than 50 percent of oak and maple.

The first comprehensive treatment of North American rodents of conservation concern. This action plan summarizes the rodent fauna of North America and provides available information on every rodent taxon that has been considered to be of conservation concern by state, provincial and private conservation agencies and regional experts. It is hoped that the survey provided in this action plan will serve as a common ground for all these parties in drawing up conservation strategies for rodents.

First published in 1991, Traditional Plant Foods of Canadian Indigenous Peoples details the nutritional properties, botanical characteristics and ethnic uses of a wide variety of traditional plant foods used by the Indigenous Peoples of Canada. Comprehensive and detailed, this volume explores both the technical use of plants and their cultural connections. It will be of interest to scholars from a variety of backgrounds, including Indigenous Peoples with their specific cultural worldviews; nutritionists and other health professionals who work with Indigenous Peoples and other rural people; other biologists, ethnologists, and organizations that address understanding of the resources of the natural world; and academic audiences from a variety of disciplines.

Although, as W.D. Billings notes in his chapter in this book. the development of physiological ecology can be traced back to the very beginnings of the study of ecology it is clear that the modern development of this field in North America is due in the large part to the efforts of Billings alone. The foundation that Billings laid in the late 1950s came from his own studies on deserts and subsequently arctic and alpine plants, and also from his enormous success in instilling enthusiasm for the field in the numerous students attracted to the plant ecology program at Duke University. Billings' own studies provided the model for subsequent work in this field. Physiological techniques. normally confined to the laboratory. were brought into the field to examine processes under natural environmental conditions. These field studies were accompanied by experiments under controlled conditions where the relative impact of various factors could be assessed and further where genetic as opposed to environmental influences could be separated. This blending of field and laboratory approaches promoted the design of experiments which were of direct relevance to understanding the distribution and abundance of plants in nature. Physiological mechanisms were studied and assessed in the context of the functioning of plants under natural conditions rather than as an end in itself.
