Available in PDF, EPUB and Kindle. Book excerpt: Investigations into the distribution and abundance of non-vascular plants have largely focused on their diversity and productivity in given environments. A trait-based approach, which considers intraspecific variation and evolution of functional traits and how plant-environment interactions influence ecosystem processes has not been explored in this plant group. A way forward is to evaluate moss traits within the context of theories such as resource economics theory (RET) and optimal partitioning theory (OPT), which provide clear mechanistic predictions for pattern of trait responses that reflects the life-history strategies of species. RET posits that plant traits are coordinated for fast or slow resource acquisition and growth strategies. OPT predicts that plants would invest in the organ receiving the most limiting resource. Collectively, these theories can provide insights into how traits influence ecophysiological adaptation of different species and the importance of intraspecific variability in this plant group. In this thesis, I used combinations of factorial and field experiments to evaluate the trait-based ecology in Sphagnum moss traits in the context of the RET and OPT. In the first chapter, I used a factorial experiment involving light, moisture and plant density to test whether two ecologically disparate Sphagnum species conformed to the fast-slow strategies predicted by RET and often observed in vascular plants. Consistent with OPT, Sphagnum diverted biomass from branch to capitulum under moisture stress to optimize atmospheric sources of moisture. In the second chapter, I used factorial experiments involving plant origin (hummock versus hollow), light, and moisture to show that intraspecific trait variability influences the range of environment that Sphagnum occupies within peatland, and therefore matters to the ecophysiology of this plant group. In the third chapter, I explore trait variability in Sphagnum moss at different spatial scales. I found that the traits varied the most within patches, which is the smallest sampling unit but also that the mechanisms controlling different traits may be operating at different spatial scales. Collectively, the studies showed that Sphagnum traits are integrated for performance but that the relationships among traits operates differently from that of vascular plants. Nonetheless, the traits are adaptable to the trait-based framework and could be tested against additional ecological theories.

This book was released on 2012-12-06 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rinie Hofstra has been a member of the Department of Plant Physiology, University of Groningen, the Netherlands, for 24 years. The nearer we came to 31 March 1985, her 65th birthday, the more we all realized how we would miss her - not only scientifically, but also socially. She left her mark on both research and teaching, always with an open mind and willing to change. After her PhD Thesis on 'Nitrogen Metabolism in Tomato Plants' she first continued working in that field, but soon started a joint project with the Department of Plant Ecology on hemiparasites. She then became involved in carbon metabolism, which resulted in her giving a Biotrop Course on C /C metabolism in 3 4 Indonesia. Her own research group, originally working on 'Nitrogen Metabolism', soon embraced 'Energy and Nitrogen Metabolism', as the research on respiration became more and more important. In running her group she showed all sides of her person. She used to stimulate and encourage everyone around her and to integrate the various lines of research. At the same time she always had an open mind for the opinion of all members of her group. And together they regularly criticized and evaluated the various projects and decided how to continue.
Download or read book Physiological Plant Ecology written by Malcolm C. Press and published by Cambridge University Press. This book was released on 2002-08 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last decade has seen rapid and major advances in our understanding of the physiological ecology of plants. This volume reviews some of these advances and new challenges. The chapters cover five broad themes: resource acquisition and utilization; interactions between organisms; responses to global environmental changes; ecosystems; and integration and scaling. This book brings together an unrivalled collection of leading practitioners in the discipline from North America, Europe and Australia and adopts a broad approach, ranging from the molecular to the ecosystem level. It has proven a valuable tool for researchers and advanced students in the discipline.

Download or read book Photosynthesis in Bryophytes and Early Land Plants written by David T. Hanson and published by Springer Science & Business Media. This book was released on 2013-10-21 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bryophytes, which are important constituents of ecosystems globally and often dominate carbon and water dynamics at high latitudes and elevations, were also among the pioneers of terrestrial photosynthesis. Consequently, in addition to their present day ecological value, modern representatives of these groups contain the legacy of adaptations that led to the greening of Earth. This volume brings together experts on bryophyte photosynthesis whose research spans the genome and cell through whole plant and ecosystem function and combines that with historical perspectives on the role of algal, bryophyte and vascular plant ancestors on terrestrialization of the Earth. The eighteen well-illustrated chapters reveal unique physiological approaches to achieving carbon balance and dealing with environmental limitations and stresses that present an alternative, yet successful strategy for land plants.

Available in PDF, EPUB and Kindle. Book excerpt: Plant Science, like the biological sciences in general, has undergone seismic shifts in the last thirty or so years. Of course science is always changing and metamorphosing, but these shifts have meant that modern plant science has moved away from its previous more agricultural and botanical context, to become a core biological discipline in its own right. However the sheer amount of information that is accumulating about plant science, and the difficulty of grasping it all, understanding it and evaluating it intelligently, has never been harder for the new generation of plant scientists or, for that matter, established scientists. And that is precisely why this Handbook of Plant Science has been put together. Discover modern, molecular plant sciences as they link traditional disciplines! Derived from the acclaimed Encyclopedia of Life Sciences! Thorough reference of up-to-the minute, reliable, self-contained, peer-reviewed articles – cross-referenced throughout! Contains 255 articles and 48 full-colour pages, written by top scientists in each field! The Handbook of Plant Science is an authoritative source of up-to-date, practical information for all teachers, students and researchers working in the field of plant science, botany, plant biotechnology, agriculture and horticulture.
