Chilean Patagonia, located at the southwestern tip of South America, is one of the last regions on earth where highly intact environments predominate. With a coastline that extends along some 100,000 km of fjords, channels, and islands, it has one of the world´s most extensive marine-terrestrial interfaces. Local place-based and Indigenous cultures and management practices are a vital presence across the region, while the long and rich history of conservation efforts have resulted in officially protected areas covering over 50% of the land and 41% of the coastal-marine area. However, Chilean Patagonia is increasingly facing anthropogenic pressures associated with increased infrastructure and access, salmon aquaculture, extractive industries, and the spread of invasive exotic species. Despite widespread recognition that Chilean Patagonia represents a unique global reservoir of socio-natural heritage, to date there has been no region-wide assessment of the scientific evidence of the conservation status of its ecosystems or the priorities for their effective conservation. Conservation in Chilean Patagonia: Assessing the state of knowledge, opportunities, and challenges is the first book to gather and synthesize the available scientific and socio-environmental information related to Patagonian conservation. It presents the collaborative work of 68 researchers and local experts, representing a range of specialties and perspectives, including: biology, ecology, socio-ecology, fisheries, aquaculture, anthropology, economics, geography, tourism, cryosphere, oceanography, climate and global change. The book’s 18 chapters focus on the status of key ecosystems and conservation tools, and provide recommendations toward the construction of a renewed, inclusive, and integrated conservation agenda for the Chilean Patagonian region. It provides an essential primer for anyone interested in the future of this ecologically vital region, as well as lessons on interdisciplinary collaboration and integrated analysis of conservation issues useful for conservation practitioners and scholars. This is an open access book. This book is a translation of an original Spanish edition. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation.

The overall objective of Reservoir Eutrophication: Preventive Management is to present the environmental and anthropogenic factors associated with the process of eutrophication and algal blooms in the Rio Verde reservoir and propose lake use and management technologies in order to minimize the problem. Eutrophication process in Rio Verde reservoir with the occurrence of intense algal blooms is a consequence of the interconnection of different climatological, hydrological, morphological, physico-chemical and biological factors, which occur not only in the watershed but also in the reservoir. Reservoir Eutrophication: Preventive Management compiles the information gathered from the development of a broad research program in Rio Verde watershed, from 2008 until 2010. Rio Verde reservoir, which was built in 1976, is located in the Metropolitan Region of Curitiba, capital of the state of Paran? in South Brazil. This reservoir is mainly used for supplying water to one of PETROBRAS Refinery. However, the reservoir is to be used for supplying drinking water to the population and that is why better understanding this system dynamics is a great concern. The book is the result of an interdisciplinary research program, which has involved more than 150 researchers, with the aim of defining a watershed management preventive system in order to prevent eutrophication processes. This way, the book combines academic rigor with practical applicability and is of interest for both researchers and technologists working in watershed management. Reservoir Eutrophication: Preventive Management is of interest to researchers and technologists that wish to examine specific characteristics of tropical climates. It is of specific interest to developing countries and for researchers interested in knowing the developed methodology adapted for temperate conditions.

Sex in Cetaceans provides an up-to-date review of multi-faceted aspects related to mating and reproduction in toothed and baleen whales. This open access book begins with discussions of sexual selection and anatomical traits related to mating and diversity between the sexes. The functions of non-conceptive copulations are reviewed as are different research techniques applied to explore sex in cetaceans. Authors and editors build knowledge of female and male social, mating, and parental strategies and tactics for several specific toothed dolphin/porpoise/whale species and baleen whale species. It concludes with a discussion of potential conservation efforts and ways to help especially beleaguered species and populations the world over. The volume is intended as a major primer of cetacean sex for undergraduate and graduate students, new and established researchers in the field, and the public wishing to learn more.

For many people, thoughts of the United Arab Emirates conjure images of ultramodern skyscrapers and rolling sand dunes. However, the Emirates are a rich mosaic of ecosystems and habitats that support surprisingly diverse communities of organisms, and there is growing awareness of the importance of these previously underappreciated natural assets. A Natural History of the Emirates provides a comprehensive overview of the unusual environmental setting of this young nation, and surveys the major ecosystems and the marine and terrestrial organisms occurring across the nation. From freshwater streams in the hyperarid Hajar Mountains to the world’s most temperature-tolerant coral reefs, the UAE is home to an astounding variety of uniquely adapted organisms that are providing insights into climate change and how organisms cope with and respond to extreme environmental conditions. The book closes with a section on human interactions with this unique environment, and proposes initiatives to ensure the protection of these unique natural assets into the future. This is an open access book.

Le lac Tchad et son avenir sont au cœur des préoccupations politiques régionales et internationales. Cet espace vital, à la charnière de l'Afrique de l'Ouest et de l'Afrique centrale, a longtemps fasciné, depuis les géographes arabes au Moyen-Âge jusqu'aux explorateurs européens du XIXe siècle. Il suscite aujourd'hui des interrogations fortes sur l'environnement, l'eau, le climat et le développement régional. Le lac Tchad va-t-il s'assécher ? Quelles seraient alors les conséquences pour les 13 millions d'hommes qui en dépendent, sur un rayon de 300 km ? Les discours publics qui traitent de l'avenir du lac Tchad, le plus souvent alarmistes, sont dans l'ensemble sources d'une grande confusion et entretiennent une image brouillée de la situation. Une connaissance précise des réalités est pourtant nécessaire pour construire une vision partagée de cet avenir et adopter une stratégie qui permette de relever les défis du développement durable du lac. La Commission du bassin du lac Tchad (CBLT) a commandé à l'Institut de recherche pour le développement (IRD) une expertise collégiale sur la préservation et le développement du lac Tchad. Cette expertise, réalisée par un collège d'experts pluridisciplinaire et paritaire Nord-Sud, recense les connaissances actuelles sur le lac et identifie les différents choix politiques susceptibles de stimuler son développement. Elle aboutit à une série de recommandations utiles aux décideurs politiques en matière de soutenabilité environnementale, de sécurité alimentaire et d'emploi. The future of Lake Chad is at the centre of regional and international political concerns. This natural habitat that links West and Central Africa fascinated Arab geographers in the Middle Ages and, later, European explorers in the 19th century. Today, it raises important questions about the environment, water, climate, and regional development. Will Lake Chad dry up? What then would be the consequences for the 13 million humans within a radius of 300 km who…

This open access book reviews the importance of ecological functioning within rangelands considering the complex inter-relationships of production agriculture, ecosystem services, biodiversity, and wildlife habitat. More than half of all lands worldwide, and up to 70% of the western USA, are classified as rangelands—uncultivated lands that often support grazing by domestic livestock. The rangelands of North America provide a vast array of goods and services, including significant economic benefit to local communities, while providing critical habitat for hundreds of species of fish and wildlife. This book provides compendium of recent data and synthesis from more than 100 experts in wildlife and rangeland ecology in Western North America. It provides a current and in-depth synthesis of knowledge related to wildlife ecology in rangeland ecosystems, and the tools used to manage them, to serve current and future wildlife biologists and rangeland managers in the working landscapes of the West. The book also identifies information gaps and serves as a jumping-off point for future research of wildlife in rangeland ecosystems. While the content focuses on wildlife ecology and management in rangelands of Western North America, the material has important implications for rangeland ecosystems worldwide.
