This book has been written to present major and efficient applications in landscape ecology, as well as to propose a solid action for this category of topics. The book aims to illustrate various treatment methods of the land-use models impact on landscape ecology creation. The book is divided into three parts: Part I: Ecological interpretation of land-use act - in this part, ecosystem and land use turn out to be a significant factor in the process of creating an ecological landscape. Part II: Landscape district in applied ecological analysis - this part attempts to illustrate the best possible model of analysis integrated with landscape in practical case studies. Part III: The anthropogenic impacts on landscape creation - this part discusses the human impact on landscape creation.

This Special Issue "Polyphenols in Crops, Medicinal and Wild Edible Plants: From Their Metabolism to Their Benefits for Human Health" presents recent studies dealing with polyphenols isolated from different food sources in terms of nutraceutical, ethnobotanical, and pharmaceutical properties. The most recent techniques of analyses were used, e.g., high throughout metabolomics analyses as well as polyphenol-based fingerprinting to generate metabolic markers. The benefits of polyphenol extracts and isolated phenolic moieties related to human pathologies were also investigated.

Für Ökonomen ist es unbestritten, dass die Umwelt als Rohstofflieferant, Schadstoffaufnahmemedium und Standortfaktor dienen soll, jedoch sollen diese Dienste der Umwelt nicht kostenlos zur Verfügung gestellt werden. Es stellt sich also die Frage, wieviel «Umwelt» ge- bzw. verbraucht werden kann. Damit ist ein Allokationsproblem definiert. Schadstoffe, die an die Umwelt abgegeben werden, akkumulieren sich z.T. im Zeitablauf; damit ist ein intertemporales Problem gegeben. Andererseits werden Schadstoffe durch Diffusionsvorgänge über Länder- und Regionengrenzen hinweggetragen; damit ist ein interregionales Problem gegeben. In dieser Abhandlung werden diese Probleme anhand eines Zwei-Regionen-Modells untersucht. Dabei wird die «Unterlieger-Oberlieger»-Problematik unter unterschiedlichen institutionellen Arrangements diskutiert.

This edited book, Invertebrates-Experimental Models in Toxicity Screening, is intended to provide an overview of the use of conventional and nonconventional invertebrate species as experimental models for the study of different toxicological aspects induced by environmental pollutants in both aquatic and terrestrial ecosystems. Furthermore, it is hoped that the information in the present book will be of value to those directly engaged in the handling and use of environmental pollutants and that this book will continue to meet the expectations and needs of all interested in the different aspects of toxicity screening.
