Synopsis Animals' Influence on the Landscape and Ecological Importance by : Friedrich-Karl Holtmeier

In its first English-language edition, this book introduces the many-faceted interactions of animal populations with their habitats. From soil fauna, ants and termites to small and large herbivores, burrowing mammals and birds, the author presents a comprehensive analysis of animals and ecosystems that is as broad and varied as all nature. Chapter 2 addresses the functional role of animals in landscape ecosystems, emphasizing fluxes of energy and matter within and between ecosystems, and the effects of animals on qualitative and structural habitat change. Discussion includes chapters on the role of animal population density and the impacts of native herbivores on vegetation and habitats from the tropics to the polar regions. Cyclic mass outbreaks of species such as the larch bud moth in Switzerland, the mountain pine beetle and the African red-billed weaver bird are described and analyzed. Other chapters discuss Zoochory – the dispersal of seeds by ants, mammals and birds – and the influence of burrowing animals on soil development and geomorphology. Consideration extends to the impact of feral domestic animals. Chapter 5 focuses on problems resulting from introduction of alien animals and from re-introduction of animal species to their original habitats, discusses the effects on ecosystems of burrowing, digging and trampling by animals. The author also addresses keystone species such as kangaroo rats, termites and beavers. Chapter 6 addresses the role of animals in landscape management and nature conservation, with chapters on the impact of newcomer species such as animals introduced into Australia, New Zealand and Europe, and the consequences of reintroduction of species to original habitat. It also discusses the carrying capacity of natural habit, public attitudes toward conversation and more. The final section ponders the effects of climate on interactions between animals and their habitats.

Synopsis White Goats, White Lies by : R. Lee Lyman

Although mountain goats are native to the Cascade range, they do not appear to have been present in Washington states's Olympic Mountains during historic times. Wildlife managers introduced goats in small numbers in what soon became Olympic National Park in 1925 and sporadically thereafter for the next twenty years. According to a 1981 statement by the National Park Service, the mountain goats in Olympic National Park "appear to be significantly altering the alpine ecosystem the park was designed to protect and preserve. As a result, park managers have argued that the goats must be eradicated". An eradication program has been in place for several years now. White Goats, White Lies does not argue for or against eradication of "exotics" in Olympic and other national parks. Rather it examines the science used to justify the current park position and questions the extent to which science is an afterthought in national park decisions.
