Book excerpt: La germination est un processus clé qui conditionne la régénération des plantes dans leur milieu ainsi que leur distribution. Connaître les conditions thermique et hydrique qui permettent aux plantes de germer est un préalable nécessaire à l’identification des menaces qui pèsent sur elles et tout particulièrement dans un contexte de changement climatique. Les modèles en temps thermique et temps hydrique permettent de prédire la phénologie de germination sur le terrain en fonction des conditions climatiques dans l’environnement de la graine dépassant des valeurs seuil de température et de potentiel hydrique de base, Tb et Ψb (i.e. respectivement la température minimale et le potentiel hydrique minimum permettant la germination).Dans ce travail de thèse, il est donc question d’étudier l’écophysiologie de la germination à l’aide de ces modèles à deux échelles taxonomiques : (i) celle des plantes à graines et (ii) à l’échelle du genre Silene de la région PACA. Dans les deux cas le but est d’évaluer les contraintes évolutives des traits de réponse au climat de la germination ainsi que leurs liens avec les contraintes morphologiques et phénologiques des plantesLes résultats de cette thèse montrent un fort signal phylogénétique des traits de germination de la température de base et une plus grande labilité pour le potentiel hydrique de base quelle que soit l’échelle taxonomique considérée. En revanche, les liens avec les traits des plantes, tels que la masse des graines, sont plus variables et dépendent à la fois de l’origine biogéographique et de la longévité des espèces.

Download or read book The Ecology of Seeds written by Michael Fenner and published by Cambridge University Press. This book was released on 2005-02-24 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: What determines the number and size of the seeds produced by a plant? How often should it reproduce them? How often should a plant produce them? Why and how are seeds dispersed, and what are the implications for the diversity and composition of vegetation? These are just some of the questions tackled in this wide-ranging review of the role of seeds in the ecology of plants. The authors bring together information on the ecological aspects of seed biology, starting with a consideration of reproductive strategies in seed plants and progressing through the life cycle, covering seed maturation, dispersal, storage in the soil, dormancy, germination, seedling establishment, and regeneration in the field. The text encompasses a wide range of concepts of general relevance to plant ecology, reflecting the central role that the study of seed ecology has played in elucidating many fundamental aspects of plant community function.

This book was released on 2020-07-18 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental and specific diversity in the Chihuahuan desert in general, and in the Cuatro Ciénegas Basin in particular, has long been recognized as outstanding. This book provides a global ecological overview, together with in-depth studies of specific processes. The Chihuahuan desert is the warmest in North America, and has a complex geologic, climatic and biogeographical history, which affects today’s distribution of vegetation and plants and generates complex phylogeographic patterns. The high number of endemic species reflects this complex set of traits. The modern distribution of environments, including aquatic and subaquatic systems, riparian environments, gypsum dunes and gypsum-rich soils, low levels of phosphorous and organic matter, and high salinity combined with an extreme climate call for a range of adaptations. Plants are distributed in a patchy pattern based on punctual variations, and many of them respond to different resources and conditions with considerable morphological plasticity. In terms of physiological, morphological and ecological variability, cacti were identified as the most important group in specific environments like bajadas, characterized by high diversity values, while gypsophytes and gypsovagues of different phylogenies, including species with restricted distribution and endemics.

Download or read book Ecophysiology of High Salinity Tolerant Plants written by M. Ajmal Khan and published by Springer Science & Business Media. This book was released on 2006-05-16 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: The halophytes are highly specialized plants, which have greater tolerance to salt. They can germinate, grow and reproduce successfully in saline areas which would cause the death of regular plants. Most halophytic species are found in salt marsh systems along seashores or around landlocked inland lakes and flat plains with high evaporation. The halophytes play very significant role in the saline areas specially in the coast by overcoming the salinity in different ways, viz. with regulating mechanisms in which excess salts are excreted and with out regulating mechanism, which may include succulents or cumulative types. Besides that they protect coast from erosion and cyclones, provide feeding ground and nursery for fish, shrimps and birds. Halophytes get increasing attention today because of the steady increase of the salinity in irrigation systems in the arid and semi-arid regions where the increasing population reaches the limits of freshwater availability. In many countries, halophytes have been successfully grown on saline wasteland to provide animal fodder and have the potential for rehabilitation and even reclamation of these sites. The value of certain salt-tolerant grass species has been recognized by their incorporation in pasture improvement programs in many salt affected regions throughout the world. There have been recent advances in selecting species with high biomass and protein levels in combination with their ability to survive a wide range of environmental conditions, including salinity.

Available in PDF, EPUB and Kindle. Book excerpt: This book is the result of a symposium dedicated to the 25th anniversary of the Delta Institute for Hydrobiological Research in Yerseke, the Netherlands. The primary idea did not come from one of the scientists working in this Institute, but from the second editor. Long before the Institute celebrated itsjubilee on 20-23 October 1982, he expressed his feelings to the other editors, that the time had come for a second European symposium on the ecology of coastal vegetation. The first symposium on this theme was held in Norwich, 12-16 September 1977, being the first meeting of the European Ecological Symposium. He only So the working group Salt waited for a suitable opportunity. Well, the 25th anniversary was a good one. Marsh Ecosystems of the Delta Institute, in close collaboration with him, adopted Dr. Rozema's initiative and set about realizing his idea. An organising committee composed of the editors of this volume, planned the scope of the meeting.

Download or read book Seed Ecology written by M.W. Fenner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about the regeneration of plants from seed under field conditions. It attempts to give a reasonably balanced overview of the many aspects of this broad topic. The first chapter introduces some general ideas about reproduction in plants. Subsequent chapters deal with the early stages in the life of a plant, from ovule to established seedling, in a more or less chronological order. The final chapter shows how the data on regeneration requirements of different species can be used to explain a number of important characteristics of whole plant communities. The study of the ecological aspects of reproduction by seed touches on a range of issues of current interest in biology. A discussion of seed size and number involves a consideration of the concepts of resource allocation, life cycles and strategies. The in teractions between plants and animals seen in pollination, seed dispersal and predation provide excellent material for the study of coevolution. Investigations on regeneration from seed have greatly our understanding of the causes and maintenance of species added to diversity. The reader will find that virtually all the experiments and field observations described in this book are conceptually very simple. Many of them merely required numerous careful measurements.

Book excerpt: The new edition of Seeds contains new information on many topics discussed in the first edition, such as fruit/seed heteromorphism, breaking of physical dormancy and effects of inbreeding depression on germination. New topics have been added to each chapter, including dichotomous keys to types of seeds and kinds of dormancy; a hierarchical dormancy classification system; role of seed banks in restoration of plant communities; and seed germination in relation to parental effects, pollen competition, local adaption, climate change and karrikinolide in smoke from burning plants. The database for the world biogeography of seed dormancy has been expanded from 3,580 to about 13,600 species. New insights are presented on seed dormancy and germination ecology of species with specialized life cycles or habitat requirements such as orchids, parasitic, aquatics and halophytes. Information from various fields of science has been combined with seed dormancy data to increase our understanding of the evolutionary/phylogenetic origins and relationships of the various kinds of seed dormancy (and nondormancy) and the conditions under which each may have evolved. This comprehensive synthesis of information on the ecology, biogeography and evolution of seeds provides a thorough overview of whole-seed biology that will facilitate and help focus research efforts. - Most wide-ranging and thorough account of whole-seed dormancy available - Contains information on dormancy and germination of more than 14,000 species from all the continents – even the two angiosperm species native to the Antarctica continent - Includes a taxonomic index so researchers can quickly find information on their study organism(s) and - Provides a dichotomous key for the kinds of seed dormancy - Topics range from fossil evidence of seed dormancy to molecular biology of seed dormancy - Much attention is given to the evolution of kinds of seed dormancy - Includes chapters on the basics of how to do seed dormancy studies; on special groups of plants, for example orchids, parasites, aquatics, halophytes; and one chapter devoted to soil seed banks - Contains a revised, up-dated classification scheme of seed dormancy, including a formula for each kind of dormancy - Detailed attention is given to physiological dormancy, the most common kind of dormancy on earth

Available in PDF, EPUB and Kindle. Book excerpt: The seed can be considered the most important plant reproductive element, as a dispersal unit for a successful reproduction in all gymnosperms and flowering plants. The formation of the seed is part of the process of reproduction in seed plants, starting with a mature ovule and following with the fertilization by pollen and some growth within the mother plant to the final outcome of an embryo developed from the zygote, the seed coat from the integuments of the ovule, and a nurturing endosperm in several species. Thanks to this key element as it is the seed, the spermatophytes now dominate all types of biological niches on land, from forests to grasslands, both in hot and cold climates. In this metadata information era, we have the chance for a deeper understanding of seed physiological and developmental processes in order to provide the fundamental basis for making plant (seed) biology research relevant and productive,coping with future challenges.

Download or read book Contributions to the ecology of halophytes written by David N. Sen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ecology of halophytes has a wide scope of interest, appealing to people of many disciplines. It covers widely different fields such as climatology, soil science, phytogeography, adaptive biology and agriculture. Ecologists study these specialized plants in relation to estuarine ecosystems, biology of dominant genera, germination ecology, water relations, salt secretion, and senescence. The present volume is divided into three parts and attempts to elucidate new aspects of the problems faced by this special group of plants. It tries to give the reader an overall view of saline environments and the ecology of plants found therein. In the first chapter of part one Zahran presents the halophytic vegetation of Egypt, which includes the inland and the littoral (Red Sea and Mediterranean Sea) salt marshes. The plants he describes have been classified as succulents, excretives and cumulatives, according to their adaptability to saline soils and according to their different life-forms. The second chapter throws light on the estuarine ecosystem ofIndia. The estuaries are described by Joshi, and Bhosale as being rich in diversity of mangrove species. Making varied use of estuarine ecosystems is not only possible, but also essential because they are the meeting point between terrestrial and marine life.
