Available in PDF, EPUB and Kindle. Book excerpt: Trees are among the longest-living organisms. They are sensitive to extreme climatic events and document the effects of environmental changes in form of structural modifications of their tissues. These modifications represent an integrated signal of complex biological responses enforced by the environment. For example, temporal change in stem increment integrates multiple information of tree performance, and wood anatomical traits may be altered by climatic extremes or environmental stress. Recent developments in preparative tools and computational image analysis enable to quantify changes in wood anatomical features, like vessel density or vessel size. Thus, impacts on their functioning can be related to climatic forcing factors. Similarly, new developments in monitoring (cambial) phenology and mechanistic modelling are enlightening the interrelationships between environmental factors, wood formation and tree performance and mortality. Quantitative wood anatomy is a reliable indicator of drought occurrence during the growing season, and therefore has been studied intensively in recent years. The variability in wood anatomy not only alters the biological and hydraulic functioning of a tree, but may also influence the technological properties of wood, with substantial impacts in forestry. On a larger scale, alterations of sapwood and phloem area and their ratios to other functional traits provide measures to detect changes in a tree’s life functions, and increasing risk of drought-induced mortality with possible impacts on hydrological processes and species composition of plant communities. Genetic variability within and across populations is assumed to be crucial for species survival in an unpredictable future world. The magnitude of genetic variation and heritability of adaptive traits might define the ability to adapt to climate change. Is there a relation between genetic variability and resilience to climate change? Is it possible to link genetic expression and climate change to obtain deeper knowledge of functional genetics? To derive precise estimates of genetic determinism it is important to define adaptive traits in wood properties and on a whole-tree scale. Understanding the mechanisms ruling these processes is fundamental to assess the impact of extreme climate events on forest ecosystems, and to provide realistic scenarios of tree responses to changing climates. Wood is also a major carbon sink with a long-term residence, impacting the global carbon cycle. How well do we understand the link between wood growth dynamics, wood carbon allocation and the global carbon cycle? Papers contribution to this Research Topic will cover a wide range of ecosystems. However, special relevance will be given to Mediterranean-type areas. These involve coastal regions of four continents, making Mediterranean-type ecosystems extremely interesting for investigating the potential impacts of global change on growth and for studying responses of woody plants under extreme environmental conditions. For example, the ongoing trend towards warmer temperatures and reduced precipitation can increase the susceptibility to fire and pests. The EU-funded COST Action STREeSS (Studying Tree Responses to extreme Events: a SynthesiS) addresses such crucial tree biological and forest ecological issues by providing a collection of important methodological and scientific insights, about the current state of knowledge, and by opinions for future research needs.

Download or read book Effects of Climate and Coastal Flooding on Tree Growth in Low lying Mid Atlantic Forests written by LeeAnn Rae Haaf and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to sea level rise, more frequent and longer duration floods are occurring in low-lying coastal forests of the Mid Atlantic. Increased flooding causes tree mortality followed by forest retreat. Previous efforts show that forest retreat is variable, however, especially in low-slope areas. Many factors likely drive this variability, so elucidating responsible mechanisms for retreat patterns, such as tree growth responses to flooding, will be important for implementing management tactics to achieve ecological goals, such as preventing forest loss. This dissertation uses tree ring analysis to study three species (Pinus taeda, Pinus rigida, and Ilex opaca) in Barnegat and Delaware Bays. Research focused on a) climate and water level relationships with tree growth; b) flood exposure and growth relative to water levels; and c) how climate change and rising sea levels might influence future growth patterns. Growth occasionally correlated with water level and climatic variables, but responses were site-specific. Counter to the expectation that tree growth inversely relates to high water levels, correlations were not always negative. Nonlinear responses to gradients in precipitation, temperature, as well as tidal water levels were also present. Future environmental conditions might benefit certain species (e.g., warmer winters for Pinus taeda), whereas others might be detrimental across sites (e.g., dryer springs). Growth responses to tidal water levels, either positive or negative, may be indicative of a transitioning system-showing that dendrochronological data are useful for determining coastal forest vulnerability to sea level rise. An improved understanding of the relative influence of climate and sea level rise on low-lying coastal forests will help resource managers make informed decisions on best tactics for sustaining these critical coastal habitats.

Available in PDF, EPUB and Kindle. Book excerpt: Flooding and Plant Growth covers the state of knowledge and opinion on the effects of flooding of soil with fresh or salt water on the metabolism and growth of herbaceous and woody plants. The book discusses the extent, causes, and impacts of flooding; the effects of flooding on soils and on the growth and metabolism of herbaceous plants; and the responses of woody plants to flooding. The text also describes the effect of flooding on water, carbohydrate, and mineral relations, as well as the effects of flooding on hormone relations and on plant disease. The adaptations to flooding with fresh water and the adaptations of plants to flooding with salt water are also encompassed. Agronomists, biochemists, plant ecologists, engineers, foresters, horticulturists, plant anatomists, meteorologists, geneticists, plant breeders, plant physiologists, and landscape architects will find the book invaluable.
Download or read book Effects of Permanently Raised Water Tables on Forest Overstory Vegetation in the Vicinity of the Tennessee Tombigbee Waterway written by Charles V. Klimas and published by . This book was released on 1982 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water tables are expected to rise somewhat in the vicinity of planned impoundments along the Tennessee-Tombigbee Waterway. Where permanent flooding of timber is anticipated, tree mortality is expected and has been accounted for in the project planning process. However, where water table levels will be raised significantly but permanent flooding does not occur, the effects on forests are very unclear. This report identifies factors that may be pertinent in assessing this type of impact. The information presented here has been drawn from the scientific literature on species flood tolerance and related topics that provide insight on potential water table effects. This review concentrates on induced mortality and changes in growth rates of mature trees. (Author).
Download or read book Hydrologic Effects of a Changing Forest Landscape written by National Research Council and published by National Academies Press. This book was released on 2008-12-19 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of all the outputs of forests, water may be the most important. Streamflow from forests provides two-thirds of the nation's clean water supply. Removing forest cover accelerates the rate that precipitation becomes streamflow; therefore, in some areas, cutting trees causes a temporary increase in the volume of water flowing downstream. This effect has spurred political pressure to cut trees to increase water supply, especially in western states where population is rising. However, cutting trees for water gains is not sustainable: increases in flow rate and volume are typically short-lived, and the practice can ultimately degrade water quality and increase vulnerability to flooding. Forest hydrology, the study of how water flows through forests, can help illuminate the connections between forests and water, but it must advance if it is to deal with today's complexities, including climate change, wildfires, and changing patterns of development and ownership. This book identifies actions that scientists, forest and water managers, and citizens can take to help sustain water resources from forests.
