Book Description
The first volume of Evolutionary Bio/ogy was published eleven years ago. Since that time eleven volumes and one supplement have appeared. As stated in earlier prefaces, we are continuing the focus of this series on critical reviews, commentaries, original papers, and controversies in evolu tionary biology. lt is our aim to publish papers primarily of greater length than normally published by society journals and quarterlies. We therefore invite colleagues to submit chapters that fall within the focus and standards of Evolutionary Bio/ogy. The Editors vii Contents 1.

Book Description
South American camelids (Llamas, Alpacas, Vicuñas and Guanacos) are receiving increased interest not only in South America but also on a worldwide scale. They possess some unique features such as their fine fibre and healthy meat, and their high adaptivity to many climatic regions across the world. Apart from the important productive aspects, their physical attractiveness and friendly temperament also makes them popular as pet animals. There are still many gaps in the scientific literature with regard to South American camelids. In part, this gap can be diminished by this collection of papers which brings the experience of both European and South American researchers working together. The main themes considered in this book are the following: nutrition and feeding, meat production and the meat market, ecology, fibre production and the fibre market, animal breeding, animal health and pathology and socio-economical aspects. The particular advantages of South American camelids for the sustainable use of fragile ecosystems with native pastures are also outlined. 'South American camelids research' is aimed at scientists and animal breeders as well as students studying veterinary, animal and applied biological sciences. It can be of further reference to farmers and traders of fibre and meat products. Please note that most articles are written in Spanish.

Book Description
Bioremediation refers to the clean‐up of pollution in soil, groundwater, surface water, and air using typically microbiological processes. It uses naturally occurring bacteria and fungi or plants to degrade, transform or detoxify hazardous substances to human health or the environment. For bioremediation to be effective, microorganisms must enzymatically attack the pollutants and convert them to harmless products. As bioremediation can be effective only where environmental conditions permit microbial growth and action, its application often involves the management of ecological factors to allow microbial growth and degradation to continue at a faster rate. Like other technologies, bioremediation has its limitations. Some contaminants, such as chlorinated organic or high aromatic hydrocarbons, are resistant to microbial attack. They are degraded either gradually or not at all, hence, it is not easy to envisage the rates of clean-up for bioremediation implementation. Bioremediation represents a field of great expansion due to the important development of new technologies. Among them, several decades on metagenomics expansion has led to the detection of autochthonous microbiota that plays a key role during transformation. Transcriptomic guides us to know the expression of key genes and proteomics allow the characterization of proteins that conduct specific reactions. In this book we show specific technologies applied in bioremediation of main interest for research in the field, with special attention on fungi, which have been poorly studied microorganisms. Finally, new approaches in the field, such as CRISPR-CAS9, are also discussed. Lastly, it introduces management strategies, such as bioremediation application for managing affected environment and bioremediation approaches. Examples of successful bioremediation applications are illustrated in radionuclide entrapment and retardation, soil stabilization and remediation of polycyclic aromatic hydrocarbons, phenols, plastics or fluorinated compounds. Other emerging bioremediation methods include electro bioremediation, microbe-availed phytoremediation, genetic recombinant technologies in enhancing plants in accumulation of inorganic metals, and metalloids as well as degradation of organic pollutants, protein-metabolic engineering to increase bioremediation efficiency, including nanotechnology applications are also discussed.

Book Description
This book presents a new approach to heritage, linking it to territory and sustainable development. This new approach entails a broader, integrated view of heritage values on the one hand, and on the other a shift in emphasis from their protection to their valorisation. In short, it provides a view of the joint workings of natural and cultural resources, and, as a consequence, moving away from a protection point of view in favour of a perspective on their suitable sustainable valorisation. In the viewpoint taken here, sustainability is understood as the balance and long-term preservation and enhancement of such natural and cultural resources and processes in a given territory. Territorial Heritage and Development includes contributions from different disciplines (geography, architecture, planning, sociology, environmental studies and archaeology) and case studies drawn from three continents, broaching both analytical and conceptual developments, and a range of initiatives for engaging in territorial heritage as an instrument of sustainable development. The book takes a pioneering and relevant approach to the breadth and complexity of the issue which can be valuable to academics and policy-makers in Geography, Architecture, Planning and Sociology.

Book Description
This book describes cases and experiences in connection with environmental and cultural ecosystem services in Argentina. It contributes to the debate in connection with different approaches to analyse ecosystem services, focusing on the environment, the Law and social perspectives and concerns. Among the topics discussed are the implementation of the National Forests Act, the regulation and recognition of ecosystem services, the role of indigenous people, the policies in place for nature and forest conservation in different regions of Argentina. This book is one of the few research studies about cultural ecosystem services developed in Latin America and presents an attractive combination of the legal, environmental and social approaches and was written by an interdisciplinary team of academics who have theoretical and practical experience in this region where there is a valuable natural and cultural heritage.
