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.

The book is concerned principally with geobotanical mapping. Geobotany is a broad science that deals with the study of species and of vegetation communities in relation to the environment; it includes other, perhaps more familiar sciences, such as plant geography, plant ecology, and chorology, and phytosociology (plant sociology). Geobotanical cartography is a field of thematic cartography that deals with the interpretation and representation, in the form of maps, of those spatial and temporal phenomena that pertain to flora, vegetation, vegetated landscapes, vegetation zones, and phytogeographical units. The production of a geobotanical map represents the last stage in a cognitive process that begins with observations in the field and continues with the collection of sample data, interpretation of the phenomena observed, and their appropriate cartographic representation; geobotanical cartography is closely tied to the concepts and scope of geobotany in general

This is the first book to be written on this fascinating, severely declining species, the black grouse. Author Patrick Laurie's lively natural history is interwoven with his account of his on-going battle to reintroduce them on his farm in the Scottish Borders. His beautiful illustrations convey his passion for these vulnerable birds, so full of character, from their aggressive lekking behaviour to their desperate struggle to survive against nearly-impossible odds in modern Britain.* Black grouse range in Britain has shrunk by 95% in the past 100 years, with 25% of that decline since the 1990s.* Mature black grouse consistently fly higher and faster than almost any other gamebird, making them fantastic, testing quarry for sportsmen.* If we allow raptor predation to increase, we risklosing this iconic bird species in Britain altogether.* During the frozen winter of 2009/10 almost half the population of black grouse being monitored by the Game and Wildlife Conservancy Trust in the more treeless North Pennines were killed off by heavy snows and frost.* The author explains why he believes it is still possible to stage a major black grouse renaissance in moorland shooting.

We need scarcely note that the topic of this book is the stuff of headlines. Around the world, political, economic, educational, military, religious, and social relations of every variety have a racial or ethnic component. One cannot begin to understand the history or contemporary situation of the United States, the Soviet Union, China, Zimbabwe, South Africa, Great Britain, Lebanon, Mexico, Canada-indeed, almost any land-without careful attention to the influence of cultural and racial divisions. Preparation of this new edition has brought a strong sense of deja vu, with regard both to the persistence of old patterns of discrimination, even if in new guises, and also to the persistence of limited and constraining explanations. We have also found, however, rich new empirical studies, new theoretical perspectives, and greatly expanded activity and analyses from members of minority groups. Although this edition is an extensive revision, with reference both to the data used and the theoretical approaches examined, we have not shifted from our basically analytical perspective. We strongly support efforts to reduce discrimination and prejudice; but these can be successful only if we try to understand where we are and what forces are creating the existing situation. We hope to reduce the tendency to use declarations and condem nations of other persons' actions as substitutes for an investigation of their causes and consequences.

The main topic of the book is a reconstruction of the evolution of nervous systems and brains as well as of mental-cognitive abilities, in short “intelligence” from simplest organisms to humans. It investigates to which extent the two are correlated. One central topic is the alleged uniqueness of the human brain and human intelligence and mind. It is discussed which neural features make certain animals and humans intelligent and creative: Is it absolute or relative brain size or the size of “intelligence centers” inside the brains, the number of nerve cells inside the brain in total or in such “intelligence centers” decisive for the degree of intelligence, of mind and eventually consciousness? And which are the driving forces behind these processes? Finally, it is asked what all this means for the classical problem of mind-brain relationship and for a naturalistic theory of mind.

The general treatment of problems connected with the causal conditioning of phenomena has traditionally been the domain of philosophy, but when one examines the relationships taking place in the various fields, the study of such conditionings belongs to the empirical sciences. Sociology is no exception in that respect. In that discipline we note a certain paradox. Many problems connected with the causal conditioning of phenomena have been raised in sociology in relatively recent times, and that process marked its empirical or even so-called empiricist trend. That trend, labelled positivist, seems in this case to be in contradiction with a certain type of positivism. Those authors who describe positivism usually include the Humean tradition in its genealogy and, remembering Hume's criticism of the concept of cause, speak about positivism as about a trend which is inclined to treat lightly the study of causes and confines itself to the statements on co-occurrence of phenomena.
