Book Description
La richesse des milieux naturels réunionnais est un pilier majeur dans le développement durable de l'île. Cette biodiversité doit ètre protégée de manière concertée par les gestionnaires d'espaces naturels et les structures de recherches scientifiques. Ces dernières sont à mème de fournir des outils d'aide à la gestion environnementale. Le PDC de Cryptopus elatus a permis de mettre en évidence la rareté de cette espèce dans son milieu et de qualifier les différents types de menaces qui s'exercent sur elle. Le braconnage et l'envahissement des habitats ont des impacts nuisibles aux populations de cette espèce. La maîtrise germinale et culturale de graines issues de fécondation artificielle est mise en place en collaboration avec le Laboratoire de Biologie de l'Université de la Réunion. Elle permet une conservation ex situ de l'espèce considérée. En effet, il a été démontré que Cryptopus elatus présentait une fructification naturelle insuffisante. L'ampleur des perturbations menaçant les populations d'Hyles biguttata, son pollinisateur, ne permet pas de mener des actions de conservation pour cet insecte.

Book Description
The freshwater eels, the Anguillids, have increasingly become the focus of attention for fisheries managers, scientists, researchers, policy makers, conservation bodies and other stakeholders. These species can be seen as a bellwether for issues affecting aquatic ecosystems – their steep decline and the management initiatives to try and reverse this trend, touch on subjects as diverse as disconnected waterways, loss of habitat, novel parasites, pollution, over-fishing and climate change. There are some 16 species of the Anguilla genus and all exhibit similar lifestyles, growing in waters often far-removed from their marine spawning grounds. These enigmatic, contradictory and confounding species share similar challenges and pressures wherever they are found. This book was generated from the 1st UK International Eel Science Symposium which was held at the Zoological Society of London (ZSL) in June 2017. Hosted by the Institute of Fisheries Management (IFM), the ZSL, and the Environment Agency (EA), the Symposium was heralded as a success, with over 180 delegates in attendance. Many of the world’s top eel specialists attended or gave presentations across a diverse range of subjects. This was one of the Symposium’s, and now the book’s great strengths – its diversity of subjects and authors. Many countries are represented within the book, from across Europe and as far afield as New Zealand, South Africa, Vanuatu, French Polynesia, Japan, Canada and the USA. The EA and IFM have collaborated to produce this landmark book which includes a mix of cultural, scientific and management information which will be invaluable to anyone with a professional or personal interest in these mysterious fish, including ichthyologists, fisheries scientists and managers, aquaculture personnel, environmental biologists and ecologists, marine and freshwater biologists, vertebrate zoologists, animal behaviourists and students studying in all these areas. Libraries in all universities and research establishments where these subjects are studied and taught should have copies on their shelves. 5m Books

Book Description
With the demise of the Old Regionalist project of achieving good regional governance through amalgamation, voluntary collaboration has become the modus operandi of a large number of North American metropolitan regions. Although many researchers have become interested in regional collaboration and its determinants, few have specifically studied its outcomes. This book contributes to filling this gap by critically re-evaluating the fundamental premise of the New Regionalism, which is that regional problems can be solved without regional/higher government. In particular, this research asks: to what extent does regional collaboration have a significant independent influence on the determinants of regional resilience? Using a comparative (Canada-U.S.) mixed-method approach, with detailed case studies of the San Francisco Bay Area, the Greater Montreal and trans-national Niagara-Buffalo regions, the book examines the direct and indirect impacts of inter-local collaboration on policy and policy outcomes at the regional and State/Provincial levels. The book research concentrates on the effects of bottom-up, state-mandated and functional collaboration and the moderating role of regional awareness, higher governmental initiative and civic capital on three outcomes: environmental preservation, socio-economic integration and economic competitiveness. In short, the book seeks to highlight those conditions that favor collaboration and might help avoid the collaborative trap of collaboration for its own sake. More specifically, this research concentrates on the effect of bottom-up, state-mandated and functional collaboration, the moderating role of regional awareness, governmental initiative and civic capital on environmental preservation, socio-economic integration and economic competitiveness. In short, the book seeks to understand whether and how urban regional collaboration contributes to regional resilience.

Book Description
S’inscrivant dans le cadre des activités de l’Observatoire juridique Natura 2000, le thème du présent ouvrage porte sur les questions juridiques que soulève l’application par le juge national – constitutionnel, administratif et judiciaire – des dispositions relatives à Natura 2000, en vue d’évaluer la contribution du juge à l’effectivité de ces dernières. Corps de règles complexe, technique, faisant appel à des concepts scientifiques ardus à interpréter pour un non-scientifique, le régime Natura 2000 n’est guère aisé à appliquer pour un juge non spécialisé. Le recours à l’expertise est souvent indispensable pour déterminer dans quelle mesure tel ou tel standard – par exemple le caractère « significatif » d’un impact – a été respecté ou non. Pour cette raison, les solutions trouvées par le juge aux différents problèmes que pose l’application du régime Natura 2000 dans les différents États membres méritent l’attention et sera enrichissante tant pour le chercheur que pour le praticien. As part of the activities of the Legal Observatory Natura 2000, this book focuses on legal issues arising from the implementation by the national courts – constitutional, administrative and judicial ones – of the provisions relating to Natura 2000, in order to assess the contribution of the judge to the effectiveness of this regime. The enforcement of this legislation, which encompasses a complex body of technical rules, grounded on scientific concepts difficult to interpret for a non-scientist, is not easy to apply by a non-specialized judge. The use of expertise is essential to determine how a particular standard – for example the «significant» character of an impact – has been met or not. For this reason, the solutions found by the judge to the various problems arising from the application of the Natura 2000 provisions in the different Member States deserve attention and will be rewarding for both researchers and practitioners.
