Visitors to Yellowstone National Park are drawn to the spectacular scenery, unique thermal features, and the large numbers of wild animals easily observed in their natural habitat. The thoughtful visitor to the park cannot help but be captivated by the unparalleled breadth of scientific knowledge needed to understand the intricate interrelationships that make up the yellowstone landscape. Knowing Yellowstone explores how scientists discover what they know about America's first national park and the surrounding lands. The chapter authors are scientists who represent the best of their fields of study. The science they describe is leading the way to our understanding of complex ecosystems worldwide.

Since the publication of the first edition more than thirty years ago, The Flora of Alberta has become the standard guide for naturalists, botanists, and all those interested in the wildlife of the province. It provides an inventory of 1775 known vascular plant species- ferns, conifers, and flowering plants - that are native to Alberta, or if non-native, that have become established and grow wild int he province. All are grouped according to genus and family, with descriptions of species, genera, and families. Keys are provided to allow for the identification of all the known species, along with information on habitats in which species generally occur. The text for each species includes the chromosome number and indicates the geographical distribution in North America. Also included are 1158 provincial distribution maps, showing the locations of native species, and two specially prepared maps of the province - one indicating the distribution of major soil groups, the other distribution of major vegetation types. In the years since its initial publication The Flora of Alberta has been revised, updated, and considerably expanded while retaining the original format and purpose that have made it indispensable to a wide range of readers.

Here is a thorough presentation and critique of the sampling approaches, designs and field techniques for measuring plant diversity. Ecologists interested in assessing landscapes and ecosystems must measure biomass, cover, and the density or frequency of various key species. Recently, sampling designs for measuring species richness and diversity, patterns of plant diversity, species-environment relationships, and species distributions have become finer-grained, as it has become increasingly important to accurately map and assess rare species for conservation. This book lays out the range of current methods for mapping and measuring species diversity, for field ecologists, resource managers, conservation biologists, and students, as a tool kit for future field measurements of plant diversity.
