Book excerpt: [Truncated] Across the globe, recognition and prioritisation of restoration ecology as a rapidly growing scientific field has never been more important to ensure we can implement large-scale and cost-effective restoration of biodiverse plant communities in a cost efficient manner. With this, re-establishing plant cover of framework species that stabilise degraded sites is one key method currently implemented to contribute to landscape scale restoration in arid systems. Yet, for regions such as the Pilbara in the northwest of Australia, rapid expansion of the mining sector has led to an unprecedented level of land clearing. To date, the current vegetation clearance for resource development in the region exceeds 120,000 ha and restoration attempts fail to reinstate the desired levels of plant diversity and vegetation cover at the scale and pace to meet the degrading influences. Given that less than 10% of sown seed results in an establishment event, considerable effort needs to be placed on understanding the reasons behind these establishment shortfalls. This study focussed on seed dormancy and germination traits as a key limiting step in the chain of seed-use, embracing the understanding that seed dormancy is a major impediment to restoration efforts, and any improvement in the quality and germination potential of a seed batch prior to sowing will provide a higher likelihood of restoration success. Therefore three core themes in this thesis were investigated: (1) a Pilbara-wide classification of seed dormancy and an assessment of the influence of temperature and chemical stimulants on germination patterns, (2) optimisation of dry afterripening (DAR) methods for seeds of a key framework genus, Triodia, with direct comparisons of physiological dormancy alleviation for florets versus seeds, and (3) the effects of wet and dry heat treatments on physical dormancy alleviation and germination of seeds from the Fabaceae and Malvaceae families.

Book Synopsis Vernal Pools in the Southwest Australian Floristic Region by : Renee E. Tuckett
Download or read book Vernal Pools in the Southwest Australian Floristic Region written by Renee E. Tuckett and published by . This book was released on 2010 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: [Truncated abstract] Vernal pools (a form of temporary wetland) of the Southwest Australian Floristic Region (SWAFR) are rich in species and endemism. There are two types of vernal pool in the SWAFR, claypans and gnammas, each with their own specialist and cosmopolitan species. Both types of vernal pool are subject to a number of localised and global threats. This is the first detailed study on the flora of claypans and gnammas in the SWAFR bringing together both biogeography and seed biology to provide practitioners the knowledge to effectively conserve the plant species occurring in these ecosystems. Biogeographical surveying of gnammas throughout the SWAFR showed that gnammas have one of the highest levels of plant endemism for any ecosystem in the SWAFR. However, species richness was not correlated with any of the environmental or morphological parameters measured. Pockets of richness were identified and found to be scattered throughout the region. I show that the drivers of species richness for gnammas differ to those of the terrestrial flora of the SWAFR and to those of the claypans. The lack of correlations and absence of shared genera between gnammas and the flora from surrounding ecosystems suggest that gnammas species have originated via long-distance dispersal attributing to the random mosaic of pools with high species richness. Germination and dormancy of seeds from claypans and gnamma species is variable with seed from some species being dormant and those from others not. While non-dormant seeds were able to germinate over a range of temperatures, temperatures upon which germination was highest was species-specific. Seeds from some species, including members of the Hydatellaceae, an early divergent angiosperm, had a germination temperature preference of 5-10 °C, lower than that previously been recorded for Australian aquatic species. In fact, for aquatic plant species worldwide, temperature preferences for germination below 15 °C are uncommon. A light preference or requirement for germination was a significant variable for all species thus I conclude that maintaining the integrity of the soil crust may be an important first step for on-site conservation of vernal pool and gnamma species. A particular focus of the thesis is the Hydatellaceae, a group of tiny annual aquatic plants that have undergone recent taxonomic realignment to the base of the angiosperm phylogenetic tree. The Hydatellaceae are important for developing our understanding of the processes of evolution in early angiosperms. I observed a type of germination, whereby the embryo differentiates outside of the seed coat, that heretofore has not been reported and thus assign a new type of specialised morphophysiological dormancy to these primitive plants. Evolution of embryo types and desiccation tolerance is also discussed in light of presented results. Ex situ storage of seeds in facilities such as seed banks is a cost effective and efficient method of plant genome conservation. Seed storage theory predicts that as storage temperature and moisture content of seeds decrease (with some limitations) the longevity of orthodox (desiccation-tolerant) seeds can be extended...

Available in PDF, EPUB and Kindle. Book excerpt: Inselbergs are isolated rock outcrops that stand out abruptly from surrounding plains. Despite the widespread occurrence of granite inselbergs throughout all climatic and vegetational zones, their remarkably rich plant life was largely neglected in the recent literature. This richly and partly in color illustrated volume provides a detailed survey of all major abiotic and biotic features characteristic for inselbergs. The extreme environmental conditions on inselbergs are described in depth as well as specific adaptive traits of rock outcrop plants including their morphological, anatomical and physiological responses. The diversity and structure of inselberg plant communities are examined on a global scale with detailed regional accounts for different tropical and temperate zones.

Book Synopsis Thermal Adaptation by : Michael J. Angilletta Jr.
Download or read book Thermal Adaptation written by Michael J. Angilletta Jr. and published by Oxford University Press. This book was released on 2009-01-29 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Temperature profoundly impacts both the phenotypes and distributions of organisms. These thermal effects exert strong selective pressures on behaviour, physiology and life history when environmental temperatures vary over space and time. Despite temperature's significance, progress toward a quantitative theory of thermal adaptation has lagged behind empirical descriptions of patterns and processes. In this book, the author draws on theory from the more general discipline of evolutionary ecology to establish a framework for interpreting empirical studies of thermal biology. This novel synthesis of theoretical and empirical work generates new insights about the process of thermal adaptation and points the way towards a more general theory. The threat of rapid climatic change on a global scale provides a stark reminder of the challenges that remain for thermal biologists and adds a sense of urgency to this book's mission. Thermal Adaptation will benefit anyone who seeks to understand the relationship between environmental variation and phenotypic evolution. The book focuses on quantitative evolutionary models at the individual, population and community levels, and successfully integrates this theory with modern empirical approaches. By providing a synthetic overview of evolutionary thermal biology, this accessible text will appeal to both graduate students and established researchers in the fields of comparative, ecological, and evolutionary physiology. It will also interest the broader audience of professional ecologists and evolutionary biologists who require a comprehensive review of this topic, as well as those researchers working on the applied problems of regional and global climate change.
Book Synopsis The Ecology of Seeds by : Michael Fenner
Download or read book The Ecology of Seeds written by Michael Fenner and published by Cambridge University Press. This book was released on 2005-02-24 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: What determines the number and size of the seeds produced by a plant? How often should it reproduce them? How often should a plant produce them? Why and how are seeds dispersed, and what are the implications for the diversity and composition of vegetation? These are just some of the questions tackled in this wide-ranging review of the role of seeds in the ecology of plants. The authors bring together information on the ecological aspects of seed biology, starting with a consideration of reproductive strategies in seed plants and progressing through the life cycle, covering seed maturation, dispersal, storage in the soil, dormancy, germination, seedling establishment, and regeneration in the field. The text encompasses a wide range of concepts of general relevance to plant ecology, reflecting the central role that the study of seed ecology has played in elucidating many fundamental aspects of plant community function.
Book Synopsis Microbes: The Foundation Stone of the Biosphere by : Christon J. Hurst
Download or read book Microbes: The Foundation Stone of the Biosphere written by Christon J. Hurst and published by Springer Nature. This book was released on 2021-05-01 with total page 684 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection of essays discusses fascinating aspects of the concept that microbes are at the root of all ecosystems. The content is divided into seven parts, the first of those emphasizes that microbes not only were the starting point, but sustain the rest of the biosphere and shows how life evolves through a perpetual struggle for habitats and niches. Part II explains the ways in which microbial life persists in some of the most extreme environments, while Part III presents our understanding of the core aspects of microbial metabolism. Part IV examines the duality of the microbial world, acknowledging that life exists as a balance between certain processes that we perceive as being environmentally supportive and others that seem environmentally destructive. In turn, Part V discusses basic aspects of microbial symbioses, including interactions with other microorganisms, plants and animals. The concept of microbial symbiosis as a driving force in evolution is covered in Part VI. In closing, Part VII explores the adventure of microbiological research, including some reminiscences from and perspectives on the lives and careers of microbe hunters. Given its mixture of science and philosophy, the book will appeal to scientists and advanced students of microbiology, evolution and ecology alike.

Book Synopsis Survival Strategies of Annual Desert Plants by : Yitzchak Gutterman
Download or read book Survival Strategies of Annual Desert Plants written by Yitzchak Gutterman and published by Springer Science & Business Media. 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.
