Book Description
Identification and Ecology of Freshwater Arthropods in the Mediterranean Basin covers the entire Mediterranean basin, including parts of Europe, Asia, Africa and the Mediterranean islands, but excluding other biogeographic locations with Mediterranean climates located outside the region. The book provides an extensive description of the taxonomy and ecology of aquatic arthropods encountered in lentic and lotic habitats, as well as in less studied underground and estuarine habitats. It offers expanded taxonomic identification keys to major groups of arthropods with a description of their ecology and distribution. Keys for insects include aquatic larval stages and water-dwelling adults of Coleoptera and Heteroptera. Additional sections focus on taxa that can be encountered in adjacent brackish and estuary ecosystems as long as the taxon primarily occurs in freshwaters. This is a much-needed, comprehensive resource on the taxonomy and ecology of freshwater arthropods with an introduction to recent molecular tools for identifications. It will be particularly useful for freshwater ecologists, limnologists, environmentalists and students in the ecological sciences. Presents taxonomic keys to genera and species to the majority of aquatic arthropod families Provides coverage of all freshwater ecosystems of the Mediterranean basin, with case studies and examples Includes numerous photographs of the aquatic arthropods described in the chapters Covers the ecology and taxonomy of organisms living in more traditionally studied lakes and streams as well as in less studied underground and estuarine habitats

Book Description
Mediterranean islands exhibit many similarities in their biotic ecological, physical and environmental characteristics. There are also many differences in terms of their human colonization and current anthropogenic pressures. This book addresses in three sections these characteristics and examines the major environmental changes that the islands experienced during the Quaternary period. The first section provides details on natural and cultural factors which have shaped island landscapes. It describes the environmental and cultural changes of the Holocene and their effects on biota, as well as on the current human pressures that are now threats to the sustainability of the island communities. The second section focuses on the landscapes of the largest islands namely Sicily, Sardinia, Corsica, Cyprus, Crete, Malta and the Balearics. Each island chapter includes a special topic reflecting a particular characteristic of the island. Part three presents strategies for action towards sustainability in Mediterranean islands and concludes with a comparison between the largest islands. Despite several published books on Mediterranean ecosystems/landscapes there is no existing book dealing with Mediterranean islands in a collective manner. Students, researchers and university lecturers in environmental science, geography, biology and ecology will find this work invaluable as a cross-disciplinary text while planners and politicians will welcome the succinct summaries as background material to planning decisions.

Book Description
When a scientific journal like "Oecologia Aquatica" reaches its tenth issue, it is perhaps not an occasion for extraordinary celebration. However, if it turn out that this coincides with a series of unusual circunstances, then the perspective changes somewhat. Moreover, if the editors hasten to confess that this modest milestone of issue na 10 was really taken as an excuse to pay tribute to Professor Ramon Margalef, who was the founder, the first director and the driving force behind the journal, we can be forgiven for waiting to celebrate.

Book Description
Within the last few decades, arachnology in the Neotropical region has experienced a great development filling the knowledge gap in one of the most diverse regions of the world. Nevertheless, large geographical areas remain poorly sampled, especially within the Amazon, and new genera and species have been continuously discovered, even in urban areas. In congruence with the recent improvements in research, several aspects of the ecology, behaviour and natural history of spiders, such as interactions with other predators and parasitoids, social interactions, dispersal patterns, habitat requirements, mating behaviors, among others, are being carefully investigated. These recent contributions incorporate substantial information on the preexisting knowledge on these subjects every year. Our main objective with this book is to present a summary on these new researches and on the currently knowledge on the main subjects involved in the general theme, emphasizing the contribution of the rich fauna of the Neotropical region to the research of behaviour and ecology of the spiders.

Book Description
This book describes the latest advances in systems biology in four plant-based marine ecosystems: seaweeds, seagrasses, microalgae, and corals. Marine organisms that inhabit the oceanic environment experience a diverse range of environmental fluctuations, anthropogenic stress, and threats from invasive species and pathogens. System biology integrates physiology, genomics, transcriptomics, proteomics, and metabolomics into numerical models and is emerging as an important approach to elucidate the functional adaptations of marine organisms to adverse environmental conditions. This book focuses on how ecophysiology, omics platforms, their integration (a systems biology perspective), and next generation sequencing tools are being used to address the stress response of marine seaweeds, seagrasses, corals, marine microbe diversity, and micro-and macroalgae/corals-bacterial interactions to global climate change and anthropogenic activities. The contents of the book are of special interest to graduate and postgraduate marine biology students and marine biology researchers, particularly those interested in marine ecology, stress physiology of marine macrophytes/corals/phytoplankton, and environmental microbiology. This book would also be of interest to marine engineers engaged in the management and conservation of our valuable marine resources.

Book Description
Molecular methodologies are crucial to our understanding of human population diversity, as well as our evolutionary relationships with nonhuman primates. The completion of the Human Genome Project has given researchers a complete human reference sequence of genes. Combined with very important advances in sequencing and bioinformatics technologies, genetic research projects are now of a multidisciplinary nature. Anthropologists have the tools to seek information related to questions concerning the origin of the human species. Genomics in Biological Anthropology: New Challenges, New Opportunities explores the impact of new advances in molecular methods, such as DNA sequencing, amplification and analysis on our knowledge about the genetics of prehistoric and existing humans. Topics covered in this volume include an overview of genomic projects, mitochondrial DNA (mtDNA) analysis, ancient DNA, mutation rates in chromosome Y, genomics of isolated populations, complex phenotypes and forensic anthropology. This volume is a concise primer for students and general readers learning the basics about human genetics, human evolution and biological anthropology

Book Description
The Ecological Bases for Lake and Reservoir Management provides a state-of-the-art review of the range of ecologically-based techniques necessary for the holistic management of lakes and their catchments. Most of the methods, case studies and national policies reviewed are directed towards management of the largest problem - eutrophication - with the emphasis on the multiple-scale approach needed for successful management and restoration. Case studies come from the USA and ten European countries, and range from single lakes through to lake districts and national inventories. Several essays precede the practical chapters with thought-provoking comments on the political, social and economic climate of water management.
