Introduction to the series. Archiearinae, Oenochrominae, Geometrinae
The Lepidoptera are without doubt the best known insect order in today’s Europe. Nevertheless there is still a great lack of knowledge in some groups, such as the Geometridae. The northern and central European fauna is relatively well known, but the distribution and bionomics of a number of species are poorly known. This problem is much more marked in southern Europe where no books on Geometridae have been published for nearly a century. Data on the bionomics are frequently unavailable which makes it difficult to assess environmental threats to the geometrid species. Information on distribution is still grossly incomplete and many records have been based on misidentifications. These proble...
The Mosaic-Cycle Concept of Ecosystems
The first international congress for ecology took place in 1974 in The Hague, its central theme being "Unifying Concepts in Ecology". In the forefront of discussion at that time were questions of constancy, stability and resilience. Such questions have gone slightly out of fashion and the exceptionally precise and well thought-out concepts of that era are seldom applied nowadays. The present book introduces another unifying concept, the concept of the ecological cycle, or, more precisely, the mosaic-cycle concept of ecology. The following chapters have their origin in lectures which were held and discussed at a symposium of the Werner Reimers Stiftung in Bad Homburg. The purpose of the symposium was the preparation of this book. Our warmest thanks go to the Reimers Stiftung for their assistance and hospitality. We should also like to express our gratitude to all participants, to those who contributed to the discussion, and above all to those colleagues whose lectures provided, from a variety of aspects, a critical approach to the mosaic-cycle concept.

Fauna der Schweizer Auen
Auengebiete machen nur einen geringen Anteil der Schweizer Landesfläche aus. 10 Prozent der untersuchten heimischen Tierarten sind auf diese Lebensräume angewiesen. Sie gelten in der Schweiz als überdurchschnittlich stark gefährdet. Insgesamt können 84 Prozent der heimischen Arten in Auen vorkommen. Die hier vorgestellte Öko-Fauna-Datenbank umfasst das Wissen über die Ansprüche der einzelnen Arten. Damit lassen sich Aussagen zur Qualität von Lebensräumen machen und Auswirkungen von Eingriffen in Lebensräume abschätzen. Unseres Wissens existiert keine faunistische Datenbank mit einer vergleichbaren Anzahl berücksichtigter Tiergruppen und Auswertungsmöglichkeiten. Auenspezifische Fragestellungen werden mit Hilfe dieser Datenbank betrachtet.
The Death of Our Planet's Species
The present rate and extent of species extinction -- estimated by some scientists as one species every 20 minutes -- are unprecedented in the history of mankind. Human activities are responsible for nearly all species loss, yet ethical aspects of this crisis are rarely mentioned. Any concern expressed tends to be over potentially valuable resources -- information for scientists, or compounds that could be used in new medicines -- that are lost when a species disappears. In The Death of Our Planet's Species, Martin Gorke argues that such a utilitarian perspective is not only shortsighted but morally bankrupt. Holding doctoral degrees in both ecology and philosophy, Gorke is uniquely qualified...
Avian Migration
P. Berthold and E. Gwinnd Bird migration is an intriguing aspect of the living world - so much so that it has been investigated for as long, and as thoroughly, as almost any other natural phenomenon. Aristotle, who can count as the founder of scientific ornithology, paid very close attention to the migrations of the birds he ob served, but it was not until the reign of Friedrich II, in the first half of the 13th century, that reliable data began to be obtained. From then on, the data base grew rapidly. Systematic studies of bird migration were introduced when the Vogelwarte Rossitten was founded, as the first ornithological biological observation station in the world (see first chapter "In M...
Nature Conservation
Many things happen in nature reserves that are contradictory at first glance. For example, flower meadows are mown down during maintenance work, even though all the plants growing there are protected. Elsewhere, protected reed beds are burnt down in a fen or the top layer of soil is removed with bulldozers in a dune conservation area. Still other areas are to remain completely untouched by human intervention. The author Klaus-Dieter Hupke shows the different strategies of nature conservation. He also shows that nature conservation is mostly not exactly what the term says in essence: "protection of nature". On the contrary, in Central Europe nature conservation areas are predominantly the rel...
Classical Political Economy and Modern Theory
Heinz Kurz is recognised internationally as a leading economic theorist and a foremost historian of economic thought. This book pays tribute to his outstanding contributions by bringing together a unique collection of new essays by distinguished economists from around the world. Classical Political Economy and Modern Theory comprises twenty essays, grouped thematically into five sections. Part I examines political economy and its critique, Part II looks at entrepreneurship, evolution and income distribution, Part III discusses Cambridge, Keynes and macroeconomics, Part IV explores crisis and cycles, whilst Part V is dedicated to personal reminiscences. The essays in this book will be an invaluable source of inspiration for economists interested in economic theory and in the evolution of economic thought. They will also be of interest to postgraduate and research students specialising in economic theory and in the history of economic thought.
