Book excerpt: L'OBJECTIF DE CE TRAVAIL EST D'ETUDIER, DE MANIERE GLOBALE, LA STRUCTURE DES PEUPLEMENTS PISCICOLES DES LACS NATURELS ET RETENUES ARTIFICIELLES FRANCAIS, EN RELATION AVEC LES FACTEURS ENVIRONNEMENTAUX ET ANTHROPIQUES. LE MANQUE DE CONNAISSANCE DES ICHTYOCENOSES EN MILIEUX LENTIQUES, EST APPARU COMME L'UN DES OBSTACLES MAJEURS A LA MISE EN PLACE DE PROTOCOLES DE GESTION PISCICOLE RAISONNES. CETTE GESTION DOIT REPONDRE A UNE DEMANDE CROISSANTE DE L'ACTIVITE HALIEUTIQUE EN EAU DOUCE. UNE ENQUETE NATIONALE EFFECTUEE AUPRES DES GESTIONNAIRES A PERMIS D'EVALUER LES MODES DE GESTION APPLIQUES AUX PLANS D'EAU. SON EXPLOITATION SOULIGNE LE BESOIN DE CONNAISSANCE SUR CES MILIEUX.

Download or read book Contingent Valuation written by R. Carson and published by Edward Elgar Publishing. This book was released on 2012-01-01 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: This major reference work the first of its kind provides a comprehensive and authoritative introduction to the large and growing literature on contingent valuation. It includes entries on over 7,500 contingent valuation papers and studies from over 130 countries covering both the published and grey literatures. This book provides an interpretive historical account of the development of contingent valuation, the most commonly used approach to placing a value on goods not normally sold in the marketplace. The major fields catalogued here include culture, the environment, and health application. This bibliography is an ideal starting point for researchers wanting to find other studies that have valued goods or used techniques similar to those they are interested in. For those wanting to conduct meta analyses, the book will serve as an invaluable guide to source material. For those wanting to conduct meta analyses, the book will serve as an invaluable guide to source material. In addition to the print edition we offer access, for purchasers of the book, to a website providing the contents of as a searchable Word document and in a variety of standard bibliographic database forms. Contingent Valuation is an indispensable reference source for researchers, scholars and policymakers concerned with survey approaches to the problem of environmental valuation.

Download or read book Lake Pavin written by Télesphore Sime-Ngando and published by Springer. This book was released on 2016-10-31 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents the first multidisciplinary scientific work on a deep volcanic maar lake in comparison with other similar temperate lakes. The syntheses of the main characteristics of Lake Pavin are, for the first time, set in a firmer footing comparative approach, encompassing regional, national, European and international aquatic science contexts. It is a unique lake because of its permanently anoxic monimolimnion, and furthermore, because of its small surface area, its substantially low human influence, and by the fact that it does not have a river inflow. The book reflects the scientific research done on the general limnology, history, origin, volcanology and geological environment as well as on the geochemistry and biogeochemical cycles. Other chapters focus on the biology and microbial ecology whereas the sedimentology and paleolimnology are also given attention. This volume will be of special interest to researchers and advanced students, primarily in the fields of limnology, biogeochemistry, and aquatic ecology.

Download or read book Biology and Ecology of Pike written by Christian Skov and published by CRC Press. This book was released on 2018-01-09 with total page 533 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book sets out to bridge the order scales among pike researchers, populations, communities, management, and fisheries. It emphasizes the progress of pike research during the last two decades, during which the order-bridging approach emerged. This framework underpins the text and the message, to convey its importance to pike research and to fish research in general. In addition, a considerable part of the book is devoted to management implications and highlights aspects of human dimensions in recreational fisheries.

Download or read book Diagnostic am nagement et gestion des rivi res 2e d written by DEGOUTTE Gérard and published by Lavoisier. This book was released on 2012-11-20 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: AFIN DE FACILITER LA MISE SUR PIED D'UN PLAN DE GESTION PISCICOLE DE LA RIVIERE DORDOGNE ET D'ENVISAGER LA REALISATION D'AMENAGEMENTS, PLUSIEURS RECHERCHES ONT ETE REALISEES. LE BUT DU PRESENT TRAVAIL EST DE METTRE AU POINT UNE METHODE D'ANALYSE QUI FACILITE L'ETABLISSEMENT D'UN DIAGNOSTIC PISCICOLE ET LA MISE EN PLACE DE PROCEDURES DE GESTION ADAPTEES. LA PREMIERE PARTIE DEFINIT LES PRINCIPAUX ASPECTS DE LA VIE PISCICOLE A TRAVERS L'ANALYSE DES PHENOMENES DE REPRODUCTION DES EXIGENCES D'ABRIS ET DE NOURRISSAGE. DANS LA SECONDE PARTIE, DIRECTEMENT ISSUE DES CONCLUSIONS DE LA PREMIERE, LES METHODES ET LES TECHNIQUES D'ETUDES SONT MISES EN PLACE. LA TROISIEME PARTIE DEFINIT LE CADRE DE L'ETUDE : - LA RIVIERE DORDOGNE ET SES CARACTERISTIQUES MORPHOLOGIQUES ET DYNAMIQUES (DE CETTE ETUDE SONT ISSUS LES DESCRIPTIFS DES PRINCIPAUX FACIES RENCONTRES), - LA PHYSICOCHIMIE DES EAUX, - LA BIOLOGIE DU COURS D'EAU ET PLUS PARTICULIEREMENT L'ETUDE DU PEUPLE- MENT PISCICOLE A TRAVERS L'UTILISATION DU MILIEU PAR ESPECES. LA QUATRIEME PARTIE TRAITE DE L'HABITABILITE DE LA RIVIERE POUR LES DIFFERENTES ESPECES DE POISSONS. UN NOUVEL INDICE (INDICE DE QUALITE GLOBALE DE L'HABITAT) EST PROPOSE ET SA FIABILITE EST ANALYSEE ET CRITIQUEE POUR LA RIVIERE DORDOGNE. LA DERNIERE PARTIE CONSTITUE L'APPLICATION DE LA METHODE D'ANALYSE PRO- POSEE, A LA MISE EN PLACE D'UN PLAN DE GESTION SUR UN TRONCON TYPE DE LA RIVIERE DORDOGNE. ENFIN, LA CONCLUSION REPREND LES PRINCIPAUX RESULTATS PRESENTES DANS CETTE ETUDE.
