Book Synopsis Emergent Properties of Plant Hydraulic Architecture by : Valentin Couvreur
Download or read book Emergent Properties of Plant Hydraulic Architecture written by Valentin Couvreur and published by Presses universitaires de Louvain. This book was released on 2013-11-13 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a context of increasing needs for food production and limited availability of freshwater for irrigation, understanding the process of root water uptake (RWU) at the plant scale has become a key issue. The complexity of root system hydraulics as well as the difficulty to measure RWU has made of modelling a valuable tool to investigate this process. However major limitations exist regarding (i) the cost of characterising root segments hydraulic properties, and (ii) the computing time of RWU from that scale. This study demonstrates that simple laws, governing RWU at the plant scale, emerge from water flow equations at the root segment scale. In conditions of uniform soil water potential (SWP), RWU is shown to be distributed proportionally to standard fractions (SUF) along the root system. Under spatially heterogeneous SWP, a compensatory RWU term proportional to a root system conductance parameter (Kcomp) is added, which increases water uptake at locations where SWP is higher. Eventually, another root system conductance parameter (Krs) defines leaf water potential from both plant transpiration rate and sensed SWP, which, itself, is the SUF-weighted-mean SWP. The emergent hydraulic parameters (SUF, Kcomp, and Krs) have a physical meaning and may be estimated or measured directly at the plant scale. They are also shown to be intimately related to the water flow available to plant leaves for transpiration, and may be useful complementary indices to characterise crop strategies against water stress. In addition, the identified emergent properties allow an extreme reduction of RWU computing time, and may even be used accurately in one-dimensional spatial discretisation for densely seeded crops such as wheat.
Book Synopsis Valuing Chaparral by : Emma C. Underwood
Download or read book Valuing Chaparral written by Emma C. Underwood and published by Springer. This book was released on 2018-04-09 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chaparral shrubland ecosystems are an iconic feature of the California landscape, and a highly biodiverse yet highly flammable backdrop to some of the fastest growing urban areas in the United States. Chaparral-type ecosystems are a common element of all of the world’s Mediterranean-type climate regions – of which California is one – yet there is little public appreciation of the intrinsic value and the ecosystem services that these landscapes provide. Valuing Chaparral is a compendium of contributions from experts in chaparral ecology and management, with a focus on the human relationship with chaparral ecosystems. Chapters cover a wide variety of subjects, ranging from biodiversity to ecosystem services like water provision, erosion control, carbon sequestration and recreation; from the history of human interactions with chaparral to current education and conservation efforts; and from chaparral restoration and management to scenarios of the future under changing climate, land use, and human population. Valuing Chaparral will be of interest to resource managers, the research community, policy makers, and the public who live and work in the chaparral dominated landscapes of California and other Mediterranean-type climate regions.
Book Synopsis Environmental Plant Physiology by : Neil Willey
Download or read book Environmental Plant Physiology written by Neil Willey and published by Garland Science. This book was released on 2018-10-26 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental Plant Physiology focuses on the physiology of plant-environment interactions, revealing plants as the key terrestrial intersection of the biosphere, atmosphere, hydrosphere and geosphere. It provides a contemporary understanding of the topic by focusing on some of humankind's fundamental biological, agricultural and environmental challenges. Its chapters identify thirteen key environmental variables, grouping them into resources, stressors and pollutants, and leading the reader through how they challenge plants and how plants respond at molecular, physiological, whole plant and ecological levels. The importance of taking account of spatial and temporal dimensions of environmental change in order to understand plant function is emphasised. The book uses a mixture of ecological, environmental and agricultural examples throughout in order to provide a holistic view of the topic suitable for a contemporary student audience. Each chapter uses a novel stress response hierarchy to integrate plant responses across spatial and temporal scales in an easily digestible framework.

Download or read book Frontiers in Plant–Soil Interaction written by Tariq Aftab and published by Academic Press. This book was released on 2021-05-01 with total page 662 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants face a wide range of environmental challenges, which are expected to become more intense as a result of global climate change. Plant–soil interactions play an important role in the functioning of ecosystems. Soil properties represent a strong selection pressure for plant diversity and influence the structure of plant communities and biodiversity. The complexity of plant–soil interactions has recently been studied by developing a trait-based approach in which responses and effects of plants on soil environment are quantified and modelled. This fundamental research on plant–soil interaction in ecosystems is essential to transpose knowledge of functional ecology to environmental management.Frontiers in Plant-Soil Interaction: Molecular Insights into Plant Adaptation will address topics that provide advances in understanding plant responses to soil conditions through the integration of genetic, molecular, and plant-level studies of diverse biotic and abiotic stresses under field and laboratory conditions. This book will be beneficial to students and researchers working on stress physiology and stress proteins, genomics, proteomics, genetic engineering and other fields of plant-soil interactions. Frontiers in Plant-Soil Interaction will also help scientists explore new horizons in their area of research. Brings together global leaders working in the area of plant–environment interactions and shares their research findings Presents current and future scenarios for the management of stressors Illustrates the central role for plant-soil interactions in applying basic research to address current and future challenges to humans
Book Synopsis Channels and Channel Control Structures by : K. V. H. Smith
Download or read book Channels and Channel Control Structures written by K. V. H. Smith and published by Springer Science & Business Media. This book was released on 2013-11-21 with total page 770 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of water resources has proceeded at an amazing speed around the world in the last few decades. The hydraulic engineer has played his part: in constructing much larger artificial channels than ever before, larger and more sophisticated control structures, and systems of irrigation, drainage and water supply channels in which the flow by its nature is complex and unsteady requiring computer-based techniques at both the design and operation stage. It seemed appropriate to look briefly at some of the developments in hydraulic design resulting from this situation. Hence the idea of the Conference was formed. The Proceedings of the Conference show that hydraulic engineers have been able to acquire a very substantial base of design capability from the experience of the period referred to. The most outstanding development to have occurred is in the combination of physical and mathematical modelling, which in hydraulic engineering has followed a parallel path to that in other branches of engineering science. The Proceedings of this Conference will give to the reader an awareness of the current state of hydraulic design in open channel flow and open channel control structures. K.V.H. Smith Editor 1.

Download or read book Forest Management and the Water Cycle written by Michael Bredemeier and published by Springer Science & Business Media. This book was released on 2010-10-25 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: The protective function of forests for water quality and water-related hazards, as well as adequate water supplies for forest ecosystems in Europe, are potentially at risk due to changing climate and changing land-management practices. Water budgets of forest ecosystems are heavily dependent on climate and forest structure. The latter is determined by the management measures applied in the forestry sector. Various developments of forest management strategies, imposed on a background of changing climate, are considered in assessing the overall future of forest–water interactions in Europe. Synthesizing recent research on the interactions of forest management and the water regime of forests in Europe and beyond, the book makes an important contribution to the ongoing dialogue between scientists dealing with different scales of forest-water interactions. This collaborative endeavour, which covers geographic and climatic gradients from Iceland to Israel and from southern Spain to Estonia and Finland, was made possible through the COST Action "Forest Management and the Water Cycle (FORMAN)", which was launched in 2007 (http://www.forestandwater.eu/). The book will be of particular interest to the research community involved in forest ecosystem research and forest hydrology, as well as landscape ecologists and hydrologists in general. It will also provide reference material for forest practitioners and planners in hydrology and land use.
