Available in PDF, EPUB and Kindle. Book excerpt: This book comprehensively describes biological phenomena, adaptation mechanisms, and strategies of living organisms to survive under extremely cold or desiccated conditions at molecular, cellular, and organ levels. It also provides tremendous potential for applications of the findings to a wide variety of industries. The volume consists of three parts: Part 1, Adaptation Mechanisms of Cold, and Part 2, Adaptation Mechanisms of Desiccation, collect up-to-date research on mechanisms and strategies of living organisms such as sleeping chironomids, polar marine fishes, hibernating mammals, bryophytes, dormant seeds, and boreal plants to survive under extreme cold and desiccated conditions at molecular, cellular, and organ levels. Part 3, Application Technologies from Laboratory to Society, covers various applications to a wide variety of industries such as the medical, food, and agricultural and life science industries. For example, biological knowledge of how plants and animals survive under cold, drought, and desiccated conditions may provide a hint on how we can improve crop production in a very fragile environment in global climate change. Unique molecules that protect cells during desiccation and freezing such as trehalose and antifreeze protein (AFP) have potential for use to preserve cells, tissues, and organs for the long term under very stable conditions. In addition, the current progress of supercooling technology of cells may lead us to solve problems of cellular high sensitivity to freezing injury, which will dramatically improve the usability of these cells. Furthermore, knowledge of water substitution and glass formation as major mechanisms for formulation designs and new drying technologies will contribute to the development of food preservation and drug delivery systems under dry conditions. Written by contributors who have been conducting cutting-edge science in related fields, this title is recommended to a wide variety of readers who are interested in learning from such organisms their strategies, mechanisms, and applications, and it will inspire researchers in various disciplines.

This book was released on 2002-08-28 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annual desert plant species of unrelated taxa in the Negev Desert of Israel have developed complementary sets of adaptations and survival strategies as ecological equivalents with physiological, morphological and anatomical resemblances, in the various stages of their life cycles. After 40 years of research in hot deserts Yitzchak Gutterman provides a comprehensive treatise of such adaptations and strategies. In doing so he covers the following topics: post-maturation primary seed dormancy, which prevents germination of maturing seeds before the summer; seed dispersal mechanisms with escape or protection strategies; cautious or opportunistic germination strategies; seedling drought tolerance. The day-length is an important factor in regulating flowering as well as the phenotypic plasticity of seed germination which is also affected by maternal factors.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the next 100 years, ecosystems in California are expected to experience warmer temperatures and an increase in the frequency and intensity of droughts. California grasslands are also heavily invaded by European annual grasses, and climate change may further favor these exotic invaders over native species. Restoration efforts in California grasslands would benefit from ways to identify taxa that are best suited to withstand increasing drought stress, including the traits that are common among the most successful drought survivors. The traits and strategies promoting severe drought survival in native perennial grasses have been relatively little explored, and drought survival is rarely studied in conjunction with seasonal patterns of growth or ecologically important (i.e., "functional") traits. In the first chapter of this dissertation, we integrated physiological and functional trait-based approaches to characterize seasonal growth dynamics and drought survival strategies in eight California wildland perennial grass species. We paid special attention to summer dormancy, an adaptation to drought that is known to be expressed by several California perennial grasses, but has received very little empirical study. Summer dormant species in our study were characterized by greater springtime productivity; earlier reproduction; a shallower, finer root system; and high tolerance of tissue dehydration. Together, these traits suggest that in spring, summer dormant taxa exhibit a resource acquisitive functional strategy, escaping drought via efficient competition for resources and early reproduction. Owing to functional similarity with many exotic annual grasses, we suggest that summer dormancy may play an important ecological role in restoring native perennial species to California grasslands. Local plant populations are recommended for ecological restoration to avoid maladaptation to current site conditions; however, whether they will be well adapted to future climate scenarios, including increasing drought stress, is a major concern for practitioners. In the second chapter, we extended the approach from Chapter 1 to characterize intraspecific variation in drought survival, seasonal growth dynamics, and functional traits in a suite of five populations of Elymus glaucus, a native perennial bunchgrass commonly used in restoration. We chose populations from sites with contrasting climates to determine how trait and environmental variability are related. We found strong intraspecific variation in dehydration tolerance, which was tightly correlated with summer dormancy. Dehydration tolerance was associated with a conservative functional strategy, and with increasing summer climatic water deficit at populations' sites of origin. Trait variation was most associated with annual climatic water deficit, rather than summer aridity, which highlights the need to measure traits during both the drought period and the more productive growing season when considering species from temporally variable climates. Our results suggest that restoration practitioners may be able to predict dehydration tolerance from summer aridity alone, but that climate during the growing season may be just as important for ecological restoration. Local adaptation evolves in response to both abiotic and biotic selective pressures. Biotic factors like competition have received far less empirical study, but functional ecology predicts that they will be more important in productive environments. In the third chapter, we used a reciprocal transplant experiment to determine whether patterns of trait variation expressed in Chapter 2 were indicative of local adaptation. Because populations were collected from contrasting productive and stressful sites, we asked whether intraspecific competition was a more important modulator of plant fitness in productive coastal sites, and whether coastal populations were more competitive. We did not find consistent evidence of local adaptation in our populations. We found that competition was more important to reproductive output at coastal sites, but only for resident populations. This result suggests that, especially at coastal sites, receiving all the benefits of locally sourced plant materials in grassland restoration requires careful consideration of the optimal intraspecific planting neighborhood.

Available in PDF, EPUB and Kindle. Book excerpt: What do peasants do in the face of severe food crisis and ecological stress, and how do they manage to survive on their own? This study revolves around a case study conducted by the author in the awraja (district) in the Ambassel Wollo province in northeastern Ethiopia. This is in the region that was hit hardest by the 1984-85 famine, which Rahmato calls "the worst tragedy rural Ethiopia had ever experienced". The author also critically examines other literature on famine response. The focus of this study is on what happens before famine comes, and how the peasants prepare for it. From a wealth of evidence, the author concludes that the seeds of famine are sown during the years of recovery.
