Book Description
Biology of Halophytes is a monograph on the biological aspects of halophytes and their behavior under saline conditions. It explores the physioecological characteristics of halophytes, such as reproduction, growth, metabolism, water relations, mineral nutrition, salt transport, salt secretion, and salt resistance. It also provides ecological information on higher marine plants, particularly submerged angiosperms, mangroves, and high coast plants. Organized into 16 chapters, this volume begins with an overview of sources of salinity and the development and nature of salines and salt-affected soils. It proceeds with a discussion of the classification of halophytes, their mutual relationships, distribution, and sociology. It also summarizes autecological information on some terrestrial halophytes and introduces the reader to the formative effects of salinity, interrelationships between plants and spatial distribution within the community, ion transport and mineral nutrition, and regulation of salt content of shoots, before concluding with a short review on ecotypic differentiation in halophytes. This book will be a valuable resource for advanced students, as well as teachers of plant and environmental sciences.

Book Description
This book focuses on morphological and anatomical strategies developed by halophytes during evolution that allow them to survive in high-salt environments. These adaptive strategies refer to well integrated structural features, such as succulence, salt secretion (salt glands and vesicular hairs), aerenchyma, Kranz anatomy, bulliform cells, successive cambia, tracheoidioblasts and endodermis with pronounced Casparian strips. The authors present cross sections of the roots, stems and leaves of 62 halophyte species belonging to 18 families from different habitats and climates (temperate, Mediterranean). They also discuss the ecological, physiological and evolutionary aspects of the various adaptive structures in an integrative way. Beginning with the structural level, this book offers novel insights into the ecology of halophytes and opens new perspectives for the identification of salt-tolerant crop plants or halophytes that can be used for ecological purposes, such as bio-remediation and revegetation.

Book Description
This book contains current knowledge and the most recent developments in the field of halophyte biology, ecology, and potential uses. Halophytes are characterized as plants that can survive and complete their life cycle in highly saline environments. This book explores the adaptive mechanisms and special features of halophytes that allow them to grow in environments that are unsuitable for conventional crops and considers their role as a source of food, fuel, fodder, fiber, essential oils, and medicines. Halophytes and Climate Change includes coverage of: - Special morphological, anatomical, and physiological features of halophytes - Ion accumulation patterns and homeostasis in halophytes - Potential use of halophytes in the remediation of saline soil - Growth and physiological response and tolerance to toxicity and drought - Mangrove ecology, physiology, and adaptation Written by a team of international authors and presented in full color, this book is an essential resource for researchers in the fields of plant physiology, ecology, soil science, environmental science, botany, and agriculture.

Book Description
Areas with high agricultural potential include arid zones, which make up 43% of the worlds total area. In these areas the scarce precipitation and the high salinity of the soils represent a limitation for the development of conventional agriculture. For this reason, it is essential to guide the efforts of research to generate agricultural technologies that allow us to optimize the productivity of those areas. Halophytes have a wide diversity of plant forms and have been regarded as a rich source of potential new crops.Next, the nutritional profile of four promising species of chenopodiaceae family are collected from saline areas of Iran were evaluted by standard methods. The nutrient content of four halophyte plants indicate that they have high nutritive and dietary values, so these medicinal plants can be used as a major source of minerals and natural nutrients in food and fodder, based on their crude protein, fat, fiber, carbohydrate, vitamins and minerals in sufficient amount.The physiological mechanisms underlying the ability of halophytes to grow well under saline soils are explored. Additionally, several theories of growth stimulation mechanisms advocated in the past and presumed mechanisms of growth stimulation are discussed in the context of the latest reports.The authors go on to review the potential of halophytes for various uses in the Mediterranean area and assess how a knowledge of their cellular machinery can help to determine the best species and genotypes for their applied uses.Following this, the ancient and present-day uses of halophytes in Portugal are presented and discussed, focusing on their traditional uses and biological activities. The review concludes by suggesting future requirements and perspectives for further exploitation of these species within the context of sustainability and climate change.In southern parts of Iran for combating dust storm, people have started growing halophyte plants and trees such as Tamarix with drainage water. C. tubulosa which is collected from the central plateau of Iran has shown a high amount of K, Mg, S, Ca and P and antioxidant capacity as well as six important phenylethanoid glycoside substrates. Cistanche could be recommended to improve the economy of the area and employment, which can also encourage the local people to plant more trees and protect them.

Book Description
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.

Book Description
This book describes important anatomical adaptations in halophytes, based on a large review of relevant literature (since the 17th century) and recent research findings. Scientists involved in the study of plant biology, from a molecular to ecosystemic level, will find information about all major structural strategies of salt tolerant plants. The book starts with an introductory theoretical background, where several aspects related to the definition and classification of halophytes and saline environments are included. Major anatomical adaptations are then grouped around major concepts: succulence, tracheoidioblasts, salt secretion, Kranz anatomy, successive cambia, and bulliform cells. Each of them is treated following a general scheme: introductory considerations, anatomical basis, and ecological implications; a review of relevant literature is then conducted and the text is supported by a large number of figures, especially ink drawings and color micrographs.

Book Description
Changing desert areas for land use implies a lot of ecological problems. These and related ones are dealt with in this book covering various interdisciplinary and international aspects. Large areas in arid and semi-arid regions are already polluted in various ways. One of the biggest problems is the anthropogenic salinization by inadequate means of agriculture and irrigation. Additionally, most arid areas in the world are dramatically overgrazed. Methods and practices of a sustainable land use in deserts are urgently needed in many arid regions. This book gives a broad survey on some of the affected regions of the world as well as some case studies from elsewhere (Aral Sea, Negev desert, Namib desert etc.). Thus, basic and applied sciences are brought together. Water management in deserts, grazing systems or reclamation of desertified areas are among the topics of this book, as well as social and economic aspects.

Book Description
In biology, the very big global and thevery small molecular issues currently appear to be in the limelight ofpublic interest and research funding policies. They are in danger of drifting apart from each other. They apply very coarse and very fine scaling, respectively, but coherence is lost when the various intermediate levels of different scales are neglected. Regarding SALINITY we are clearly dealing with a global problem, which due to progressing salinization of arable land is of vital interest for society. Explanations and basic understanding as well as solutions and remedies may finally lie at the molecular level. It is a general approach in science to look for understanding of any system under study at the next finer (or "lower") level of scaling. This in itself shows that we need a whole ladder of levels with increasingly finer steps from the global impact to the molecular bases of SALINITY relations. It is in this vein that the 22 chapters of this book aim at providing an integrated view of SALINITY.

Book Description
Salinity and water stress limit crop productivity worldwide and generate substantial economic losses each year, yet innovative research on crop and natural resource management can reveal cost-effective ways in which farmers can increase both their productivity and their income. Presenting recent research findings on salt stress, water stress and stress-adapted plants, this book offers insights into new strategies for increasing the efficiency of crops under stressful environments. The strategies are based on conventional breeding and advanced molecular techniques used by plant physiologists, and are discussed using specific case studies to illustrate their potential. The book emphasizes the effects of environmental factors on specific stages of plant development, and discusses the role of plant growth regulators, nutrients, osmoprotectants and antioxidants in counteracting their adverse affects. Synthesising updated information on mechansisms of stress tolerance at cell, tissue and whole-plant level, this book provides a useful reference text for post graduate students and researchers involved in the fields of stress physiology and plant physiology in general, with additional readership amongst researchers in horticulture, agronomy, crop science, conservation, environmental management and ecological restoration.
