This book is designed to present those principles and techniques for land appraisal which are applicable to all developing countries. Examples of specific situations in which these techniques have been or might be adopted are taken primarily from monsoonal and equatorial Asia. It is in this region that the land/food/population problem is most acute. It is also the writer's region of specialization; over the past ten years out of a total of some twenty-five years working in or closely concerned with Asia, an attempt has been made to examine the major problems ofland potential in relation to rural economy and nutrition in the whole region, and in particular to show to what extent its different parts resemble or differ from each other. The geographical scope comprises mainland southern, southeast and east Asia, from Pakistan to the People's Republic of China and Korea, with the insular monsoonal and equatorial lands of Sri Lanka, Indonesia, East Malaysia, Philippines, Taiwan and Japan (part). International and bilateral agencies and specialists outside Asia repeatedly insist that Asia must learn to feed itself from the produce of its own land, or from imported foods paid for by the exports of primary and secondary commodities and of manufactured products to the developed world.

Pillars of Evolution provides a fresh and provocative perspective on adaptive evolution. Readers new to the study of evolution will find a refreshing new insight that establishes evolutionary biology as a rigorous and predictive science, whilst practicing biologists will discover a provocative book that challenges traditional approaches. The book begins by leading readers through the mechanics of heredity, reproduction, movement, survival, and development. With that framework in place, it then explores the numerous ways that traits emerge from the interactions between genetics, development, and the environment. The key message is that adaptive changes in traits (and their underlying allelic frequencies) evolve through the traits' functions and their connection with fitness. The complex mappings from genes-to-traits-to-fitness are characterized in the structure of evolution. A single "structure matrix" describes why individuals vary in the values of adaptive traits, their ability to perform the function of those traits, and in the fitness they accrue. Fitness depends on how organisms interact with and perceive their environment in time and space. These relationships are made explicit in spatial, temporal, and organizational scale that also sets the stage for the crucially important role that ecology always plays in evolution. The ecological hallmarks of density- and frequency-dependent interactions allow the authors to explore new and exciting insights into evolution's dynamics. The theories and principles are then brought together in a final synthesis on adaptation. The book's unique approach unites genetic, development, and environmental influences into a single comprehensive treatment of the eco-evolutionary process.

"Landscape Bionomics,” or “Bio-integrated Landscape Ecology,” radically transforms the main principles of traditional Landscape Ecology by recognizing the landscape as a living entity rather than merely the spatial distribution of species and communities on the territory, often analysed in separate themes (water, species, pollution, etc.). To be more exact, the landscape is identified as the "life organization integrating a set of plants, animals and human communities and its system of natural, semi-natural, and human cultural ecosystems in a certain spatial configuration." This new perspective inevitably leads to significant changes in how to assess and manage the environment. This book represents the culmination of an endeavor begun by the author, with the support of Richard Forman and Zev Naveh, more than a dozen years ago. It builds on the author’s previous successful publication, Landscape Ecology, A Widening Foundation, by addressing a range of additional topics and discussing the new theoretical and methodological concepts that have emerged during the past decade of research. Particular attention is paid to the fact that interventions in the landscape can be made with the best intentions yet cause serious damage! Against this background, the author explains the need to study "landscape units" by applying methods comparable to those used in clinical diagnosis – hence ecologists can be viewed as the “physicians” of ecological systems.

John Alcocks Standardwerk Animal Behavior - jetzt in Form eines völlig neuen Lehrbuchtyps, der speziell für die Studiensituation im deutschsprachigen Raum konzipiert wurde.* Das erfolgreiche Lehrbuch Animal Behavior stellt die verschiedenen Aspekte tierischen Verhaltens in einen evolutionsbiologischen Rahmen. Es behandelt die grundlegenden Mechanismen des Verhaltens ebenso wie seine stammesgeschichtlichen Ursachen und betont die Bedeutung der Evolutionstheorie als einigendes Element der unterschiedlichen Teildisziplinen der Verhaltensbiologie. Wichtige Konzepte werden sowohl an Wirbellosen wie an Wirbeltieren verdeutlicht. Alcocks klarer und engagierter Schreibstil macht es auch Anfängern trotz der stark konzeptionellen Ausrichtung des Werkes leicht, den Stoff zu verstehen. Die nun vorliegende achte Auflage des Standardwerkes wurde völlig neu geschrieben. Zahlreiche Erkenntnisse aus jüngster Zeit haben darin Eingang gefunden. Verständnisfragen direkt an den entsprechenden Textstellen regen dazu an, sich mit dem gerade gelesenen Stoff auseinanderzusetzen. Die beiden Kapitel über die Einflüsse von Vererbung und Umwelt auf die Entwicklung wurden vereint, um zu verdeutlichen, dass Entwicklungsprozesse sowohl von genetischen als auch von Umweltfaktoren abhängen. Der Autor führt dem Leser immer wieder vor Augen, welche Rolle der Überprüfung von Theorien und Hypothesen zukommt und dass wissenschaftliche Schlussfolgerungen immer nur vorübergehend gültig sind. So werden in diesem Buch auch kontrovers diskutierte und bisher ungelöste Probleme angesprochen. * Von Studierenden der Biowissenschaften wird heute erwartet, dass sie im Laufe ihres Studiums englische Literatur problemlos lesen und verstehen und schließlich auch Forschungsergebnisse auf Englisch kommunizieren können. Den Weg dorthin bereitet der neu entwickelte Lehrbuchtyp Easy Reading - Das Original mit Übersetzungshilfen. So bietet die vorliegende Ausgabe von Animal Behavior in einem zusammen: den englischen Originaltext deutsche Übersetzungshilfen in der Randspalte deutschsprachige Verständnisfragen / Übungsaufgaben ein englisch-deutsches Glossar deutsch- und englischsprachige Kapitelzusammenfassungen und auf der Website www.elsevier.de/alcock: eine Übersicht über die im Buch erwähnten Arten (deutsch, englisch, lateinisch) Internetlinks für Deutschland, Österreich und die Schweiz Wesentlicher Zusatznutzen der "Easy Reading"-Ausgabe ist, das Lesen des englischen Grundtextes zu erleichtern und in die spezielle wissenschaftliche Terminologie einzuführen. Wer dieses Buch durcharbeitet, steigert somit seine fachliche und seine sprachliche Kompetenz zugleich. This new edition of Animal Behavior has been completely rewritten with coverage of much recent work in animal behavior, resulting in a thoroughly up-to-date text. Notable is the inclusion, for the first time, of discussion questions embedded in the text itself, rather than appended to the end of each chapter. This format is designed to encourage students to reflect on the material they have just digested while also making it easier for instructors to promote a problem-solving approach to the subject in their classes. Another key organizational improvement is the consolidation of what had been two separate chapters on the genetic and environmental influences on development. By combining this material, the new Chapter 3 makes a stronger, more tightly argued case for the view that development is a truly interactive process codependent on both genetic and environmental factors. Like previous editions, the book shows how evolutionary biologists analyze all aspects of behavior. It is distinguished by its balanced treatment of both the underlying mechanisms and evolutionary causes of behavior, and stresses the utility of evolutionary theory in unifying the different behavio
