Arthropods are invertebrates that constitute over 90% of the animal kingdom, and their bio-ecology is closely linked with global functioning and survival. Arthropods play an important role in maintaining the health of ecosystems, provide livelihoods and nutrition to human communities, and are important indicators of environmental change. Yet the population trends of several arthropods species show them to be in decline. Arthropods constitute a dominant group with 1.2 million species influencing earth’s biodiversity. Among arthropods, insects are predominant, with ca. 1 million species and having evolved some 350 million years ago. Arthropods are closely associated with living and non-living entities alike, making the ecosystem services they provide crucially important. In order to be effective, plans for the conservation of arthropods and ecosystems should include a mixture of strategies like protecting key habitats and genomic studies to formulate relevant policies for in situ and ex situ conservation. This two-volume book focuses on capturing the essentials of arthropod inventories, biology, and conservation. Further, it seeks to identify the mechanisms by which arthropod populations can be sustained in terrestrial and aquatic ecosystems, and by means of which certain problematic species be managed without producing harmful environmental side-effects. This edited compilation includes chapters contributed by over 80 biologists on a wide range of topics embracing the diversity, distribution, utility and conservation of arthropods and select groups of insect taxa. More importantly, it describes in detail the mechanisms of sustaining arthropod ecosystems, services and populations. It addresses the contribution of modern biological tools such as molecular and genetic techniques regulating gene expression, as well as conventional, indigenous practices in arthropod conservation. The contributors reiterate the importance of documenting and understanding the biology of arthropods from a holistic perspective before addressing conservation issues at large. This book offers a valuable resource for all zoologists, entomologists, ecologists, conservation biologists, policy makers, teachers and students interested in the conservation of biological resources.

Moderne Ökologie von A bis Z Das renommierte Autorenteam Townsend, Begon und Harper konzentriert sich in diesem Lehrbuch auf die wesentlichen Zusammenhänge in der Ökologie. In anschaulicher, durchgehend vierfarbig gestalteter und leicht verständlicher Form wird ein ausgewogener Überblick vermittelt, der die terrestrische und aquatische Ökologie gleichermaßen berücksichtigt. Für den Praxisbezug wurde großes Gewicht auf die angewandten Aspekte gelegt. Zahlreiche didaktische Elemente und großzügige, farbige Illustrationen erleichtern den Zugang. Es gibt Schlüsselkonzepte am Kapitelanfang, "Fenster" für historische Einschübe, mathematische Hintergründe und ethische Fragen, Zusammenfassungen und Fragen am Kapitelende. Neu in dieser Auflage ist ein eigenes Kapitel zur Evolutionsökologie. Alle anderen Kapitel – insbesondere die zu den angewandte Aspekten – wurden intensiv überarbeitet und hunderte neue Beispiele aufgenommen. Klar und einfach erklärt in diesem Buch. Diese Softcover-Ausgabe, die ein unveränderter Nachdruck der 2. Auflage (2009) ist, hält das nachgefragte Lehrbuch weiterhin verfügbar. Aus den Rezensionen zur Hardcover-Ausgabe der 2. Auflage: “… In vierfarbig gestalteter und verständlicher Form werden sowohl die Grundlagen als auch die angewandten Aspekte von Ökologie behandelt. Dieses Buch ist übersichtlich gegliedert und für Jedermann verständlich geschrieben. Daher eignet es sich auch für Studienanfänger. … Dieses Buch bietet einen prima Überblick über die Gesamtthematik und hilft dabei, ein solides Grundverständnis aufzubauen. Nach dieser Lektüre fällt es dem Einzelnen sicherlich leichter, sich auch kompliziertere Fachliteratur zur Ökologie zu erschließen.“ Münchner Natur & Umwelt “Schon beim ersten Durchblättern fällt die lesefreundliche Gestaltung dieses Lehrbuches für – vornehmlich – Grundstudium-Biologiestudenten auf ... Die gut durchdachte didaktisch-methodische Aufmachung äußert sich zudem an den problemorientierten Randbemerkungen, die als Denkanstoß bzw. Merkhilfe dienen. Nicht nur das Layout ist zeitgemäß, auch die Inhalte spiegeln aktuell relevante ökologische Zusammenhänge wider ... Überhaupt liest sich das gesamte Werk sehr angenehm ... Für die genannte Adressatengruppe ist ‘diese Ökologie’ auf jeden Fall empfehlenswert ...“ Biologie in der Schule.

Biological Diversity and Sustainable Resources Use is a very interesting volume, including attractive overviews and original case studies mainly focused on socio-economical effects of the right management of the ecosystems biodiversity, as well as on the useful integration between human activities and environmental responses. Ecological, medical and historical aspects of the sustainable development are also discussed in this book which consists of articles written by international experts, offering the reader a clear and extensive view of the present condition in which our planet is.

A plethora of different theories, models, and concepts make up the field of community ecology. Amid this vast body of work, is it possible to build one general theory of ecological communities ? What other scientific areas might serve as a guiding framework ? As it turns out, the core focus of community ecology—understanding patterns of diversity and composition of biological variants across space and time—is shared by evolutionary biology and its very coherent conceptual framework, population genetics theory. The Theory of Ecological Communities takes this as a starting point to pull together community ecology’s various perspectives into a more unified whole. Mark Vellend builds a theory of ecological communities based on four overarching processes: selection among species, drift, dispersal, and speciation. These are analogues of the four central processes in population genetics theory—selection within species, drift, gene flow, and mutation—and together they subsume almost all of the many dozens of more specific models built to describe the dynamics of communities of interacting species. The result is a theory that allows the effects of many low-level processes, such as competition, facilitation, predation, disturbance, stress, succession, colonization, and local extinction to be understood as the underpinnings of high-level processes with widely applicable consequences for ecological communities. Reframing the numerous existing ideas in community ecology, The Theory of Ecological Communities provides a new way for thinking about biological composition and diversity.

What does the growing interest of literary criticism towards the representation of nature and its ethical implications tell us? In which folds of narrative, poetic or cinematographic discourse do the manifestations of a continuously renewed sensitivity for the contradictions of progress, for the precarious coexistence between human, animal and plant agents lie? And what kind of relationships can there be between the semantics of places and landscapes, expressed in a fictional world, and eco-criticism? Sixteen essays suspended between 'text' analysis and theory of criticism are solicited and collected by Nicola Turi, in an attempt to answer these and other questions affecting the function and orientations of contemporary criticism, its ability to give back the forms of artistic language, and at the same time its recurring temptation to confront, as Calvino's Bradamante would say, with the «life behind it that pushes and disarranges all the leaves of the book».
