Book Description
This book is the first comprehensive global review of all aspects of alien plant invasions in protected areas. It provides insights into advances in invasion ecology emanating from work in protected areas, and the link to locally relevant management support for protected areas. The book provides in-depth case studies, illuminating interesting and insightful knowledge that can be shared across the global protected area network. The book includes the collective understanding of 80 ecologists and managers to extract as much information as possible that will support the long-term management of protected areas, and the biodiversity and associated ecosystem services they maintain. “This outstanding volume draws together pretty much all that can be said on this topic, ranging from the science, through policy, to practical action”. Dr. Simon N. Stuart, IUCN Species Survival Commission, UK. "This important and timely volume addresses two of the most serious problems affecting biodiversity conservation today: assessing the extent to which protected areas are impacted by biological invasions and the complex problems of managing these impacts. Written by leading specialists, it provides a comprehensive overview of the issues and gives detailed examples drawn from protected areas across the world". Professor Vernon H. Heywood, School of Biological Sciences, University of Reading, UK

Book Description
The Anthropocene era has been marked by such significant human pressure that it has led to the sixth mass extinction. The Baseline Concept in Biodiversity Conservation interprets human domination of the Earth as the process of gradual landscape change, the execution of which is neither linear nor homogeneous. This book is structured around three key questions: Where and when did everything go wrong? How do we define baseline states for biodiversity conservation strategies? How are reference states mobilized in a concrete way through case studies? Today, biodiversity conservation faces a dilemma that this book sheds light on: return to states less modified by humans than today but in a world that has changed significantly; or, let the nature of tomorrow express itself where it still can but without a road map.

Book Description
This is the first truly ecosystem-oriented book on peatlands. It adopts an ecosystems approach to understanding the world's boreal peatlands. The focus is on biogeochemical patterns and processes, production, decomposition, and peat accumulation, and it provides additional information on animal and fungal diversity. A recurring theme is the legacy of boreal peatlands as impressive accumulators of carbon as peat over millennia.

Book Description
The erosion of biodiversity is currently highly publicized. Militant movements accuse humans of destroying nature and being responsible for a sixth mass extinction. However, this anxiety-provoking message is sometimes based on misconceptions, false or partisan ideas, and media relays that favor and amplify alarmist information. If the situation of certain populations is worrying, it is not a general phenomenon because others are expanding. Rather than holding a globalizing discourse, it is necessary to recontextualize and relativize the debate to better define the necessary actions. Biodiversity Erosion analyzes numerous scientific publications, as well as alarming discussions, emphasizing the multiple biases present in the way information is presented. This book questions the relevance of the notion of species and the desire to compile an inventory of all living things. It argues for a less Manichean approach to our relationship with nature.

Politicization of Ecological Issues

Book Description
The legitimacy of environmental policies is an issue of increasing concern for analysts. Ecological stakes are deemed to be global, but global public decisions are rare and implemented with difficulty. Dissensus prevails on environmental ethics and there is little evidence of any greening of policy tools. The global framing of the environment fails to account for how people relate to the ecological realities which surround them. Rather than placing the environment at a distance, Politicization of Ecological Issues advocates for building legitimacy from people’s perceptions of singular forms and patterns in their environment. Based on scholarly literature in political ecology and empirical cases of water policy in Europe, the book shows how the qualification of environmental realities has been politicized and translated into motives for public action. Similarly, it argues that theoretical debates addressing the ecological crisis are not only dealing with ideas, but rather advocating for specific environmental forms that are deemed to be motives of hope or worry.

Book Description
Wetland and Stream Rapid Assessments: Development, Validation, and Application describes the scientific and environmental policy background for rapid wetland and stream assessments, how such assessment methods are developed and statistically verified, and how they can be used in environmental decision-making—including wetland and stream permitting. In addition, it provides several case studies of method development and use in various parts of the world. Readers will find guidance on developing and testing such methods, along with examples of how these methods have been used in various programs across North America. Rapid wetland and stream functional assessments are becoming frequently used methods in federal, state and local environmental permitting programs in North America. Many governments are interested in developing new methods or improving existing methods for their own jurisdictions. This book provides an ideal guide to these initiatives. Offers guidance for the use and evaluation of rapid assessments to developers and users of these methods, as well as students of wetland and stream quality Contains contributions from sources who are successful in academia, industry and government, bringing credibility and relevance to the content Includes a statistically-based approach to testing the validity of the rapid method, which is very important to the usefulness and defensibility of assessment methods

Book Description
Ce manuel pratique aide à comprendre les grands principes régissant la morphologie des cours d’eau et leur dynamique pour mieux concevoir des aménagements qui sauront résister aux crues sans déséquilibrer pour autant les écosystèmes. Le chapitre 1 donne les définitions, principes de base et résultats d’hydraulique à surface libre. Les chapitres 2 à 4 approfondissent le diagnostic des rivières en tenant compte du transport solide et de la constante interaction entre l’écoulement, le fond, les berges et le champ d’inondation. Les chapitres 5 à 9 exposent les différents aménagements et entretiens pour utiliser l’eau ou se protéger des crues. Cette 2e édition, entièrement réactualisée et augmentée de nombreux schémas et photos, aborde de nouveaux points : les calculs hydrauliques des déversoirs latéraux, des estimations de débit solide adaptées aux fortes pentes, la morphologie des torrents et les conséquences morphologiques des barrages, la restauration morphologique des rivières, les processus d’érosion par surverse, la conception des zones d’expansion de crues, des procédés de protection de berge ou de traitement des digues, la nouvelle norme sur les enrochements, etc... Diagnostic, aménagement et gestion des rivières s’adresse aux professionnels en charge de la gestion et de l’aménagement des cours d’eau ou de la police de l’eau : cabinets d’ingénierie, collectivités territoriales, établissements publics, sociétés d’aménagement régional et services déconcentrés et centraux de l’État. Il sera une aide précieuse pour les étudiants en écoles d’ingénieur ou en université et intéressera les chercheurs en mécanique des fluides, géomorphologie ou écologie fluviale.
