This book explores a relatively small, but interesting and anomalous, region of Alberta between the North Saskatchewan and the Battle Rivers. Ecological themes, such as climatic cycles, ground water availability, vegetation succession and the response of wildlife, and the impact of fires, shape the possibilities and provide the challenges to those who have called the region home or used its varied resources: Indians, Metis, and European immigrants.

This is the first field guide to the identification of the birds of the islands of the tropical Pacific, including the Hawaiian Islands, Fiji, Samoa, Tonga, southeastern Polynesia, and Micronesia. It is intended both as a reference for the expert and as an introduction to birding in the region for the novice. Small enough to be carried afield, it contains much previously unpublished information about behavior, vocalizations, ecology, and distribution. The forty-five color plates depict all plumages of all bird species that breed in the islands, as well as of those that regularly visit them and the surrounding oceans, and of most species believed to be extinct on the islands. Black-and-white figures show many of the rarer visitors. Introductory sections discuss the tropical Pacific as an environment for birds, problems of birding on islands, and bird conservation. Appendixes include maps of the island groups and a thorough bibliography.

The emergence of landscape ecology during the 1980s represents an impor tant maturation of ecological theory. Once enamored with the conceptual beauty of well-balanced, homogeneous ecosystems, ecologists now assert that much of the essence of ecological systems lies in their lumpiness. Patches with differing properties and behaviors lie strewn across the land scape, products of the complex interactions of climate, disturbance, and biotic processes. It is the collective behavior of this patchwork of eco systems that drives pattern and process of the landscape. is not an end point This realization of the importance of patch dynamics in itself, however. Rather, it is a passage to a new conceptual framework, the internal workings of which remain obscure. The next tier of questions includes: What are the fundamental pieces that compose a landscape? How are these pieces bounded? To what extent do these boundaries influence communication and interaction among patches of the landscape? Will con sideration of the interactions among landscape elements help us to under stand the workings of landscapes? At the core of these questions lies the notion of the ecotone, a term with a lineage that even predates ecosystem. Late in the nineteenth century, F. E. Clements realized that the transition zones between plant communi ties had properties distinct from either of the adjacent communities. Not until the emergence of patch dynamics theory, however, has central signif icance of the ecotone concept become apparent.

Weeds are successful plants, but on their own terms. Looking at weeds from an ecological viewpoint, emphasising the way in which one species interacts with others, the authors show that weeds are questionable mainly in that they are out-of-place.
