Book Description
This book provides an integrated view of Atlantic coastal Patagonian ecosystems, including the physical environment, biodiversity and the main ecological processes, together with their derived ecosystem services and anthropogenic impacts. It focuses on the key components of the aquatic ecosystem, covering the lower levels (plankton) to the top predators like large mammals and birds, before turning to human beings as consumers and shapers of coastal marine resources. The book then presents an overview of how organisms that constitute the aquatic food webs have changed through time and how they likely will soon change due to global change processes and anthropogenic pressures. In this regard it offers a wealth of information such as long-term patterns in physical / atmospheric processes, biodiversity and the distribution of marine organisms, as well as the results of experimental studies designed to understand their responses under future scenarios shaped by both climate change and anthropogenic pressures. The book also covers various aspects of the past, present and potential future relationship of human beings with Patagonian coastal environments, including the utilization of sea products, tourism, and growth of cities.

Book Description
The Dusky Dolphin: Master Acrobat Off Different Shores covers various topics about the dusky dolphin, including its taxonomy, history and demography, ecology, and behavior. After introducing the dusky dolphin as a member of the genus Lagenorhynchus under the family Delphinidae, the book continues by describing its life history, its demographic patterns, and its role in the food web considering predation, parasitism, and competition. The book also includes chapters that discuss the interaction of the dusky dolphin with its habitats, such as the dusky dolphin's sound production, its foraging at night and in daylight, its survival strategies in response to predator threats, the mating habits of New Zealand duskies, calf rearing, sexual segregation, and genetic relationships. Other chapters address the interaction of dusky dolphins with humans. This book offers information about dusky dolphins off Southern Africa and discussions about the patterns of sympatry in Lagenorhynchus and Cephalorhynchus. Finally, comparisons between dusky dolphins and great apes as large-brained mammals are also reviewed in this book. - Only book fully devoted to the southern hemisphere "dusky" dolphin - Heavily illustrated with charts, figures, tables, and all color photos - Written by a cadre of experts intimately familiar with dolphin field work - Written in an accurate yet accessible style for the scientist and natural historian alike

Book Description
Food sovereignty is an emerging discourse of empowerment and autonomy in the food system with the development of associated practices in rural and some urban spaces. While literature on food sovereignty has proliferated since the first usage of the term in 1996 at the Rome Food Summit, most has been descriptive rather than explanatory in nature, and often confuses food sovereignty with other movements and objectives such as alternative food networks, food justice, or food self-sufficiency. This book is a collection of empirically rich and theoretically engaged papers across a broad geographical spectrum reflecting on what constitutes the politics and practices of food sovereignty. They contribute to a theoretical gap in the food sovereignty literature as well as a relative shortage of empirical work on food sovereignty in the global "North", much previous work having focussed on Latin America. Specific case studies are included from Canada, Norway, Switzerland, southern Europe, UK and USA, as well as Africa, India and Ecuador. The book presents new research on the emergence of food sovereignties. It offers a wide variety of empirical examples and a theoretically engaged framework for explaining the aims of actors and organizations working toward autonomy and democracy in the food system.

Book Description
Cephalopod Culture is the first compilation of research on the culture of cephalopods. It describes experiences of culturing different groups of cephalopods: nautiluses, sepioids (Sepia officinalis, Sepia pharaonis, Sepiella inermis, Sepiella japonica Euprymna hyllebergi, Euprymna tasmanica), squids (Loligo vulgaris, Doryteuthis opalescens, Sepioteuthis lessoniana) and octopods (Amphioctopus aegina, Enteroctopus megalocyathus, Octopus maya, Octopus mimus, Octopus minor, Octopus vulgaris, Robsonella fontaniana). It also includes the main conclusions which have been drawn from the research and the future challenges in this field. This makes this book not only an ideal introduction to cephalopod culture, but also a valuable resource for those already involved in this topic.

Book Description
The Atlantic Forest is one of the 36 hotspots for biodiversity conservation worldwide. It is a unique, large biome (more than 3000 km in latitude; 2500 in longitude), marked by high biodiversity, high degree of endemic species and, at the same time, extremely threatened. Approximately 70% of the Brazilian population lives in the area of this biome, which makes the conflict between biodiversity conservation and the sustainability of the human population a relevant issue. This book aims to cover: 1) the historical characterization and geographic variation of the biome; 2) the distribution of the diversity of some relevant taxa; 3) the main threats to biodiversity, and 4) possible opportunities to ensure the biodiversity conservation, and the economic and social sustainability. Also, it is hoped that this book can be useful for those involved in the development of public policies aimed at the conservation of this important global biome.

Book Description
Fish species that migrate within the great rivers of South America support important local fisheries but are little known outside their native range. This book represents the first collection of the work of local scientific experts on these remarkable fish. The authors cover the Upper Parani, Paraguay-Parani, Uruguay and Suo Francisco basins in Brazil, as well as the Brazilian and Colombian Amazon. They discuss not only the principal migratory species and their fascinating relationship with the water cycle in the rivers and wetlands, but also the fisheries they support, and their often precarious conservation status."

Book Description
Igapó forests are a common part of the Amazon whose ecosystems are critical to our shared human future. The introduction addresses the structure, function and dynamics of igapó forests in the Amazon basin, focusing on their uniqueness due to their high level of complexity defined as the many ways that different components of igapó forests in the Amazon basin ecosystem interact and also on how those interactions are on a higher-order compared to other tropical forests. The text then breaks down the igapó ecosystem using these sections: (1) Igapó forests over space and time, (2) Water, light and soils, (3) The carbon cycle, (4) Litter, fungi and invertebrates, (5) Vertebrates, (6) Plant population studies, (7) Plant community studies, and (8) Human impacts and management. Experts from around the world serve as chapter authors that review what is known about their specific part of the igapó ecosystem, what research they have done, and also what needs to be done in the future.
