Hors collection94-92669-10-2 2-7099-2400-5 The equilibrium of inland hydrosystems is presently a cause for concern, with species extinction rates there estimated to be 5 times higher than for terrestrial fauna in the 21st century. Urgent measures must be taken to conserve these ecosystems particularly with regard to fishes, which represent an especially rich and diverse evolutionary heritage. Fishes were long unaffected by human activity on the African continent, but anthropogenic pressure has increased in recent decades. Good management of African continental waters is thus of paramount importance in terms of heritage and economics, as fishes are a vital natural resource for the people in sub-Saharan Africa. In view of biodiversity conservation, African fishes are investigated here as a biological model owing to their enormous ecological and genetic diversity. It is essential to know the ecology and structure of various communities, and to understand the impact of human activity. This book discusses the diversity of environments, the origin and evolution of species, survival and adaptive strategies, the structure of fish communities, and the impact of human activity. It also devotes a section to fisheries and fish culture. This ambitious project summarizes the current state of knowledge on African fishes and their populations, highlighting the mechanisms regulating their equilibrium and the causes contributing to their erosion. It is a reference not just for readers involved in African aquatic environments, but for anyone interested in biodiversity conservation in general.Environmental Studiesécologiebiodiversitéexploitation des ressources naturellesécosystèmefacteur anthropiqueévolutionpiscicultureeau continentaleaquaculturefaune ichtyologiquehydrobiologiemilieu lacustrebiogéographiebiodiversitybiogeographywaterecologyecosystemevolutionressources exploitationanthropogenic factorhydrobiologyaquaculturebiodiversitybiogeographywaterecologyecosystemevolutionressources exploitationanthropogenic factorhydrobiologyEnvironmental Studiesécologiebiodiversitéexploitation des ressources naturellesécosystèmefacteur anthropiqueévolutionpiscicultureeau continentaleaquaculturefaune ichtyologiquehydrobiologiemilieu lacustrebiogéographiebiodiversitybiogeographywaterecologyecosystemevolutionressources exploitationanthropogenic factorhydrobiologyAgnèse Jean-françois1317644Albaret Jean-Jacques1317645Bigorne Rémy1287057Brummett Randall1317646Cavin Lionel960351Clément Gaël1317647Duponchelle Fabrice1317648Fermon Yves1284550Hugueny Bernard1317649Laë Raymond1297297Legendre Marc1317650Lemoalle Jacques1297298Levêque Christian627727Murray Alison1288368Otero Olga1317651Paugy Didier927625Pinton Aurélie1317652Snoeks Jos1317653Stewart Kathlyn657814Paugy Didier927625Levêque Christian627727Otero Olga1317651FR-FrMaCLEBOOK9910495820603321The inland water fishes of Africa3033000UNINA04139nam 2201069z- 450 991055729840332120210501(CKB)5400000000041055(oapen)https://directory.doabooks.org/handle/20.500.12854/68852(oapen)doab68852(EXLCZ)99540000000004105520202105d2020 |y 0engurmn|---annantxtrdacontentcrdamediacrrdacarrierAdvances in Dam EngineeringBasel, SwitzerlandMDPI - Multidisciplinary Digital Publishing Institute20201 online resource (202 p.)3-03936-326-3 3-03936-327-1 Expansion of water resources is a key factor in the socio-economic development of all countries. Dams play a critical role in water storage, especially for areas with unequal rainfall and limited water availability. While the safety of existing dams, periodic re-evaluations and life extensions are the primary objectives in developed countries, the design and construction of new dams are the main concerns in developing countries. The role of dam engineers has greatly changed over recent decades. Thanks to new technologies, the surveillance, monitoring, design and analysis tasks involved in this process have significantly improved. The current edited book is a collection of dam-related papers. The overall aim of this edited book is to improve modeling, simulation and field measurements for different dam types (i.e. concrete gravity dams, concrete arch dams, and embankments). The articles cover a wide range of topics on the subject of dams, and reflect the scientific efforts and engineering approaches in this challenging and exciting research field.History of engineering and technologybicsscalkali-silica reactionarch damscentral clay coreconcrete arch damsconcrete damconcrete damsconcrete gravity damscrack predictiondam safetydamagedamsdownstream shoulderdynamic capacityearth damearthfill damendurance time analysisexcavationexisting concrete damfailurefieldfinite element analysisfinite elementsgeodetic monitoringgroundwaterhealth monitoringinstrumentationlong-term behaviourmovementn/anon-linear finite element analysesnonlinearpassive rock boltperformance based earthquake engineeringprobabilisticprogressive failurerainfallreservoir level fluctuationsresponse correlationsaturation degreeseasonal temperature variationsseepageseismicseismic effectsseismic fragility analysissettlementssoil nailspatialstability assessmentstochasticstructural safety and reliabilitytemperatureuncertainty quantificationvariabilityHistory of engineering and technologyHariri-Ardebili M.
