Book Synopsis Biologie des populations animales et végétales by : Claude Henry
Download or read book Biologie des populations animales et végétales written by Claude Henry and published by . This book was released on 2001 with total page 709 pages. Available in PDF, EPUB and Kindle. Book excerpt: Une population animale ou végétale est un ensemble d'individus appartenant à la même espèce, susceptibles de se reproduire entre eux, et occupant une aire géographique commune. La biologie des populations s'intéresse aux propriétés collectives des individus organisés en populations et à l'évolution de ces propriétés au cours du temps. Cet ouvrage synthétise les principaux apports expérimentaux et théoriques des disciplines concernées par les populations animales et végétales : démographie, dynamique et génétique des populations, biologie évolutionniste, écologie. La première partie présente les concepts, méthodes et résultats élaborés dans les domaines de la démographie, de l'écologie et de la génétique (analyse et projections démographiques, contrôle naturel des effectifs, structure génétique). La seconde partie est consacrée à la sélection et à l'évolution de nombreuses caractéristiques des cycles biologiques (les " traits de vie " : proportion des sexes, systèmes de fécondation, dispersion, longévité et sénescence, effectif des progénitures, etc.) et s'intéresse à la manière dont elles sont modelées par la sélection naturelle. La compréhension de certaines " histoires de vie ", et donc du processus de la sélection naturelle, ainsi que l'influence de l'Homme sur la Nature, sont explicitées par de nombreux exemples pris à la fois dans le monde animal et dans le monde végétal. Des applications abordent aussi les problèmes d'exploitation des populations naturelles, de contrôle d'espèces jugées nuisibles et de conservation des espèces menacées d'extinction. Cet ouvrage très documenté s'adresse aux étudiants du deuxième cycle universitaire en sciences de la vie et en écologie, ainsi qu'aux chercheurs et aux candidats aux concours d'enseignement.

Book Synopsis La génomique en biologie végétale by : Jean-François Morot-Gaudry
Download or read book La génomique en biologie végétale written by Jean-François Morot-Gaudry and published by Editions Quae. This book was released on 2004 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage illustre de façon claire et pédagogique les méthodes et les concepts qui sont à la base des progrès de la génomique en biologie végétale (grands programmes internationaux de séquençage, outils de la bio-informatique, méthodes d'analyse de l'expression des gènes incluant leurs produits métaboliques finaux et leur spécificité tissulaire et/ou cellulaire). Il rend compte des applications potentielles de la génomique dans les domaines de la génétique et de l'amélioration des plantes, de l'écophysiologie et de l'agronomie. Ce livre s'adresse aux étudiants de fin d'études universitaires ou agronomiques, aux professeurs de l'enseignement supérieur, aux techniciens, aux ingénieurs et scientifiques qui souhaitent acquérir des connaissances en génomique végétale.

Book Synopsis L'optique dans les instruments : Applications à la médecine et à la biologie by : GOURE Jean-Pierre
Download or read book L'optique dans les instruments : Applications à la médecine et à la biologie written by GOURE Jean-Pierre and published by Lavoisier. This book was released on 2013-04-01 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les instruments jouent un rôle primordial dans l’avancée scientifique et technologique. Les ouvrages de cette mini-série consacrée à l’optique dans les instruments ont pour but de montrer que l’optique et les composants optiques constituent souvent la partie essentielle autour de laquelle interviennent l’électronique, la mécanique et l’informatique. Le premier tome a décrit les bases nécessaires à la compréhension des phénomènes physiques mis en jeu. Ce second tome a pour but d’illustrer par divers exemples le rôle fondamental de l’optique dans l’instrumentation destinée à la biologie et à la médecine. Sont développés quelques instruments utilisés en routine pour l’analyse et la caractérisation, des instruments de très haute complexité permettant aux chercheurs d’avoir accès à des mesures ultra précises ainsi que des technologies prometteuses actuellement en développement. Enfin ces exemples permettront de voir l’impact des lasers non seulement dans l’instrumentation mais aussi dans les soins médicaux depuis l’ophtalmologie jusqu’à la chirurgie et le traitement de nombreuses maladies.
Book Synopsis Genetic Management of Fragmented Animal and Plant Populations by : Richard Frankham
Download or read book Genetic Management of Fragmented Animal and Plant Populations written by Richard Frankham and published by Oxford University Press. This book was released on 2017 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the greatest unmet challenges in conservation biology is the genetic management of fragmented populations of threatened animal and plant species. More than a million small, isolated, population fragments of threatened species are likely suffering inbreeding depression and loss of evolutionary potential, resulting in elevated extinction risks. Although these effects can often be reversed by re-establishing gene flow between population fragments, managers very rarely do this. On the contrary, genetic methods are used mainly to document genetic differentiation among populations, with most studies concluding that genetically differentiated populations should be managed separately, thereby isolating them yet further and dooming many to eventual extinction Many small population fragments are going extinct principally for genetic reasons. Although the rapidly advancing field of molecular genetics is continually providing new tools to measure the extent of population fragmentation and its genetic consequences, adequate guidance on how to use these data for effective conservation is still lacking. This accessible, authoritative text is aimed at senior undergraduate and graduate students interested in conservation biology, conservation genetics, and wildlife management. It will also be of particular relevance to conservation practitioners and natural resource managers, as well as a broader academic audience of conservation biologists and evolutionary ecologists.

Book Synopsis The ecology and management of African wetland vegetation by : Patrick Denny
Download or read book The ecology and management of African wetland vegetation written by Patrick Denny and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in the biology of African 'wetlands' was initiated in the last century with the hypothesis that Lake Tanganyika was once part of a Jurassic sea, and was furthered by Cunnington's expedition at the beginning of this century which proved that it was not. In the late 1920's, ecological studies, encouraged by the growing importance of inland fisheries, were started hy British, French and Belgian biologists. Some twenty years later several government limnological research centres and fishery departments were established in tropical Africa, and scientific progress was accelerated. Scientific collaboration between the regions south of the Sahara was started formally in 1951 by the Scientific Council for Africa and stimulated by the International Biological Programme (1964-74) with its emphasis on biological productivity. Some of its interests were takcn on by SCOPE which recently selected continental wetlands as a Special Project; hence this book. The five authors, with-Patrick Denny as editor, have made a very valuable contribution both to science and to thc management of Africa's natural rcsourccs: thcy have filled a gap in the synthesis of knowledge about Africa's environments which is long overdue. The term 'wetland' is used today in several different contexts. For this purpose, it excludes the seas and large open inland waters. which are too deep for rooted plants, but includes the huge areas of floodplains and dambos which may change seasonally from standing water to very dry lands.
