Book excerpt: From the Abstract: The purpose of this study was to determine physiological differences in drought response among Garry oak (Quercus garryana Douglas ex Hook. [Fagaceae]) seedlings that grow in distinct populations in Washington state, in order to aid in restoration efforts by informing growers of the potential differences between the acorn collection sites. Acorns from six Washington populations east of the Cascades, as well as one population from Whidbey Island, were collected and grown in containers under controlled conditions. The plants were assessed with and without moderate and severe drought stress induced by withholding water. The most extreme differences in photosynthetic characteristics for non-stressed seedlings from different populations were in stomatal conductance rates, which in some cases differed between populations by 2 fold or more. Differences in response to drought occurred across populations after 14 days of withholding water (Fig 4). Seedlings from the northernmost population of Garry oak on the east side of the Cascades (Swauk Creek) were most susceptible to lowered photosynthetic rates induced by drought stress, while an island population from the west side of the cascades (Oak Harbor) showed the least drought-induced reduction of assimilation. Differences among populations were also observed in the occurrence of drought induced embolisms, and in changes in leaf water potential, relative water content, and production of the osmolyte proline in response to drought. This study shows that seedlings from different populations of Garry oak have distinct physiological responses to drought that may lead to changes in survivorship for seedlings used in reforestation efforts for Garry oak savannas as they are exposed to drought stress in the field.

This book was released on 2023-11-02 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monitoring Forest Damage with Mass Spectrometry-Based Metabolomics Methods Understand forest responses to climate change with this timely introduction Forests are among the most critical parts of our global ecosystem, responsible for the air we breathe, home to most of the earth’s species, and crucial sources of food and raw materials. Forest development is therefore one of the most important areas of ecological study, and damage to forests is potentially existential. Metabolomics, a toolkit which accrues data on interactions between genetic and environmental conditions, promises to advance our understanding of how these vital ecosystems respond to dramatic changes in climate and environment. Monitoring Forest Damage with Mass Spectrometry-Based Metabolomics Methods offers a thorough, accessible discussion of metabolomic techniques and their applications in forest tree research. It promises to enrich the reader’s understanding of how forests are being transformed by globe-spanning changes, and to arm researchers with tools for reacting to these potentially epochal developments. Monitoring Forest Damage with Mass Spectrometry-Based Metabolomics Methods readers will also find: Analysis of specialized secondary metabolites such as phytohormones Detailed discussion of ecologically important tree genera such as Pinus, Populus, Quercus, and many more Supplementary materials related to study design, sample preparation, and instrumental analysis protocols Monitoring Forest Damage with Mass Spectrometry-Based Metabolomics Methods is ideal for researchers in analytical chemistry, mass spectrometry, metabolomics, forest research, the life sciences, and all other related fields.

Download or read book Physiological and Fitness Consequences of Seasonal Rainfall Variation in Neotropical Live Oak Seedlings Quercus Oleoides written by Alyson Center and published by . This book was released on 2015 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Broadly distributed species often span a large range of environmental conditions, which pose contrasting physiological challenges. Such species are thought to persist across this heterogeneity, either by locally adapting or by evolving wide environmental tolerances via phenotypic plasticity or maintaining high genetic variation. The extent to which populations display local adaptation, phenotypic plasticity, and high within-population genetic variation will have large impacts on species responses to climate change. Large-scale habitat fragmentation impedes migration making plasticity and adaptation important mechanisms for in situ persistence. Using common gardens with reciprocal plantings we investigated the consequences of changes in water availability in the broadly distributed tropical live oak, Quercus oleoides. Chapter 1 examines the relationship among seed production timing, germination and seedling fitness at the local scale in dry forests of NW Costa Rica. In chapter 2, I investigate the extent to which four populations of Q. oleoides from regions with contrasting rainfall patterns exhibit local adaptation and the role of changes in water availability on seedlings fitness. In chapter 3, I examine the extent that populations exhibit differentiation in traits related to carbon and water use. Chapter 3 also investigates the role of trait plasticity in seedling responses to changes in seasonal water availability and the patterns of phenotypic selection on traits. Results from these studies show that local-scale differences in seed production timing have significant consequences for germination and seedling fitness. At a larger spatial scale, results of this work indicate that the broadly distributed Q. oleoides does not consist of a series of locally adapted populations, but rather, of populations with wide environmental tolerances. Seedlings from all populations show similar physiological and morphological responses to changes in water availability and differences among garden sites. Trait plasticity contributes more to phenotypic trait variation than within-population genetic differences. Overall, populations of Q. oleoides lineage represent a lineage well-adapted to drought. Populations are able to maintain fitness with changes in water availability in the short-term through plasticity but may be limited in their long-term adaptive capacity to future changes in rainfall patterns due to low within-population genetic variation for physiological traits.

Available in PDF, EPUB and Kindle. Book excerpt: Bioactive Foods in Promoting Health: Probiotics and Prebiotics brings together experts working on the different aspects of supplementation, foods, and bacterial preparations, in health promotion and disease prevention, to provide current scientific information, as well as providing a framework upon which to build clinical disease treatment studies. Since common dietary bacterial preparations are over-the-counter and readily available, this book will be useful to the growing nutrition, food science, and natural product community that will use it as a resource in identifying dietary behavioral modifications in pursuit of improved health as well as for treatment of specific disease, as it focuses on the growing body of knowledge of the role of various bacteria in reducing disease risk and disease. Probiotics are now a multi-billion-dollar, dietary supplement business which is built upon extremely little research data. In order to follow the 1994 ruling, the U.S. Food and Drug Administration with the support of Congress is currently pushing this industry to base its claims and products on scientific research. Research as shown that dietary habits need to be altered for most people whether for continued or improved good health. The conclusions and recommendations from the various chapters in this book will provide a basis for those important factors of change by industry with new uses. Animal studies and early clinical ones will lead to new uses and studies. Particularly the cutting edge experimental and clinical studies from Europe will provide novel approaches to clinical uses through their innovative new studies. Heavy emphasis on clinical applications (benefits and/or lack thereof) as well as future biomedical therapeutic uses identified in animal model studies Focused on therapies and data supporting them for application in clinical medicine as complementary and alternative medicines Key insights into gut flora and the potential health benefits thereof Health scientists and nutritionists will use this information to map out key areas of research. Food scientists will use it in product development Information on pre-and probiotics as important sources of micro-and macronutrients Aids in the development of methods of bio-modification of dietary plant molecules for health promotion Coverage of a broad range of bacterial consituents Nutritionists will use the information to identify which of these constituents should be used as dietary supplements based on health status of an individual Science-based information on the health promoting characteristics of pre-and probiotics Provides defense of food selections for individual consumption based on health needs and current status Diverse international authoring team experienced in studying prebiotics and probiotics for medical practice Unusally broad range of experiences and newly completed clinical and animal studies provides extended access to latest information
