Dieses Lehrbuch gibt dem Studenten einen Überblick über alle wichtigen Lebensräume des Meeres: von den Küstengebieten bis hin zur Tiefsee und dem Meeresboden, von den Packeiszonen bis zu den Korallenriffen. Es setzt den Schwerpunkt auf diejenigen Lebensräume im Meer, die die großen Flächen der Erdoberfläche ausmachen und eine entsprechend große Bedeutung für die Biosphäre der Erde haben - z.B. bei der aktuellen Diskussion darüber, wieviel Kohlendioxid die Weltmeere aufnehmen können.

The identification of inputs and outputs is the first and probably most important step in testing and analyzing complex systems. Following accepted natural laws such as the conservation of mass and the principle of electroneutrality, the input/output analysis of the system, be it steady or in connection with perturbations will reveal the status dynamic, will identify whether changes are reversible or irreversible and whether changing the input will cause a hysteresis response. Moreover, measurements ofinput and output fluxes can indicate the storage capacity ofa system, its resilience to buffer or amplify variations of the external input, and it can identify structural changes. Therefore, to a certain extent, the input/output analysis can facilitate predictions about the ecosystem stability. The measurement of fluxes and the determination of inputs and outputs of eco systems are, in many aspects, analogous to measurements done by engineers when testing an electronic apparatus. The first step is the measurement ofthe input/output properties of the instrument as a whole, or ofvarious circuit boards, and the compari· son ofthese with the expected variations of the original design. Varying input and out· put can give valuable information about the stability and the regulatory properties of the device. Nevertheless, only the circuit as an entity has specific properties which cannot be anticipated if the individual components are investigated regardless oftheir position. Also, the instrument as a whole will have different input/output properties than its subcircuits.

This textbook on Protistology provides an excellent information source for a broad audience ranging from students of advanced university courses to senior scientists, for the study of parasitic and/or pathogenic microorganisms; lavishly and unsurpassedly illustrated with about 800 single micrographs, line drawings and diagrams allowing an overwhelming insight into the architectural variety of unicellular creatures and their dynamical properties. The pivotal ecological roles unicellular organisms play in the bionomics of life on earth, at present and in the past as well as the phylogenetic relationships between unicellular and multicellular organisms are thoroughly explained.

The translation of this volume has been a long and sometime arduous journey giving nearly literal meaning to the Latin term translatus, meaning to carry across. In fact, it required many journeys both geographically, between Canada and Germany, and fig uratively, between German and English language, thought, and culture; between the mind of a German professor and that of his American colleague. Whether or not it was all worthwhile must be left to the reader's judgment, but let me outline the rationale for embarking on this venture. When the first German edition of this book appeared in 1980 it was acclaimed not only by German scholars but by those outside the German-speaking community as well. In fact, it received extremely favorable reviews, even in English-language journals, which is unusual for a foreign text. It was recognized that this was far more than just another text book on motivation. For one thing, it exposed and examined the multi faceted roots that have contributed to contemporary theory and research in motivation. The author skillfully examined the motivational concepts, theories, and research that have emanated from many areas of psychology such as learning theory, social psychol ogy, personality, psychoanalysis, and clinical psychology.

La 4ème de couverture porte : "Echinoderms are a vast group of spiny-skinned animals including starfish, brittle-stars, sea urchins, sand dollars, feather stars, sea lilies and sea cucumbers. These relatives of chordates and hemichordates have inhabited the world's oceans for more than 500 million years. Modern members of the Echinodermata are, with over 7 000 species, an integral part of marine communities from the intertidal to the deep sea. Echinoderms play a major ecological role in marine habitats and are of economic importance in fisheries, aqaculture and biomedicine.The present volume contains the abstracts of lectures and posters presented during the 7th European Conference on Echinoderms (ECE) as well as excursion guides.This year's conference was held at the northern campus of the Georg-August University in Göttingen, Germany, from October 2-9, 2010. More than 100 biologists, palaeontologists and other scientists from 25 countries participated."

No one can ever have secure knowledge about the gods and creatures, and should anyone hit by chance upon the right thing, he will not know it for sure; that is why everything that we believe to be true is "opinion". XENOPHANES around 500 B.C. (According to ROD 1988, p.85) The goal of phylogenetic systematics (cladistics) is to discover the kinship relations between all organisms on earth and to translate the order we perceive in Nature into an equivalent man-made system. Although the goal is easily formulated, the path is thorny, and the results achieved continue to be imperfect. This is the fate of any science that bases its propositions on the interpretation of histor ical evidence. The diversity found in the millions of species originated as a result of the continuous splitting of biopopulations through time. Combined with this was the emergence of hierarchically linked des cent communities of species. We call the process of origin of descent communities phylogenesis. We do not know, however, the exact course of phylogenesis - we can only formulate hypotheses. The historical evidence at hand consists of the feature patterns of extant species and of extinct species with their combination of original and derived traits which are the result of evolution.

Changing desert areas for land use implies a lot of ecological problems. These and related ones are dealt with in this book covering various interdisciplinary and international aspects. Large areas in arid and semi-arid regions are already polluted in various ways. One of the biggest problems is the anthropogenic salinization by inadequate means of agriculture and irrigation. Additionally, most arid areas in the world are dramatically overgrazed. Methods and practices of a sustainable land use in deserts are urgently needed in many arid regions. This book gives a broad survey on some of the affected regions of the world as well as some case studies from elsewhere (Aral Sea, Negev desert, Namib desert etc.). Thus, basic and applied sciences are brought together. Water management in deserts, grazing systems or reclamation of desertified areas are among the topics of this book, as well as social and economic aspects.
