Download or read book Guyana written by Barry Munslow and published by Routledge. This book was released on 2019-06-04 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: First published in 1998, this volume uses Guyana as an excellent, comprehensive case study to examine various sectors’ operations, effects upon the environment and the ways in which the sector can impact upon the vitality and development potential of other sectors. The authors attempt to demonstrate how it is possible to adjust current sectoral activities for improved resource utilisation. They begin in the interior looking at mining and forest resource exploitation. Attention then moves towards the coast, looking at agriculture, fishing, human settlement and service provision. A review of industry, transport and energy follows before examining biodiversity, tourism and the Amerindian community. Finally, a detailed analysis is presented of the challenges to be faced in devising a sustainable development national strategy.

Download or read book Soils of Tropical Forest Ecosystems written by Andreas Schulte and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: An understanding of the characteristics and the ecology of soils, particularly those of forest ecosystems in the humid tropics, is central to the development of sustainable forest management systems. The present book examines the contribution that forest soil science and forest ecology can make to sustainable land use in the humid tropics. Four main issues are addressed: characteristics and classification of forest soils, chemical and hydrological changes after forest utilization, soil fertility management in forest plantations and agroforestry systems as well as ecosystem studies from the dipterocarp forest region of Southeast Asia. Additionally, case studies include work from Guyana, Costa Rica, the Philippines, Malaysia, Australia and Nigeria.

Book excerpt: Following its predecessors, Plant Roots: The Hidden Half, Fifth Edition is thoroughly updated and reports the major changes that have taken place in root research since the last edition published over 10 years ago. Considered a widely acclaimed book in the field of plant sciences, this edition includes a broad array of topics reflecting progress being made in the subdomains of root biology, featuring chapters on modern topics, while retained chapters are fully updated to demonstrate significant developments made in our understanding of root biology and in fast-evolving research methodologies and techniques. It reviews all root-related processes, from the evolution of roots in past eras to single-cell genomics, allowing readers to grasp an overall view of the state-of-the-art research in this field. Among the 104 contributors to this book are seasoned experts in the field, as well as uprising specialists who have already made a distinguished mark in scientific literature. All of the chapters are extensively referenced featuring specific information on any topic related to the biology of the hidden half of plants. Featuring full color illustrations throughout, this handbook is an essential source of information for both expert and novice root scientists.
Download or read book Photosynthetic Characterisation of Tropical and Temperate Rainforest Species written by Nur Hazwani Binti Abdul Bahar and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rubisco catalyses a rate-limiting step in photosynthesis and is the largest nitrogen sink in leaves. The maximum rate of carboxylation of Rubisco, Vcmax, is routinely estimated from gas exchange using the Farquhar, von Caemmerer & Berry 1980 model of photosynthesis. As Vcmax allows mechanistic representation of photosynthesis, it has been incorporated into terrestrial biosphere models to estimate global primary productivity. However, doubts remain about previous estimates of Vcmax for globally important biomes, such as moist forests, both in tropical and temperate regions. In my thesis, I present a survey of Vcmax values - calculated assuming infinite mesophyll conductance - along a 3,300-meter elevation gradient from lowland western Amazon to the Andean tree line in Peru; this region is home to the largest moist forest on Earth. Large variations in Vcmax were found within and across the 18 field sites. As hypothesised, when estimated at a common measuring temperature (25°C), average Vcmax values of lowland Amazon trees were significantly lower than that of Andean trees. When data for the lowland Amazon and upland Andean trees were combined, the resultant mean tropical Vcmax value was lower than that of temperate trees reported in past studies. My analysis points to low Vcmax of Peruvian tropical trees being linked to limitations in phosphorus supply, and to a high proportion of Rubisco being inactive. The second part of my thesis investigated how mesophyll conductance influences the estimation of Vcmax for several Australian tropical (i.e. warm-adapted) and temperate (i.e. cool-adapted) moist-forest trees. Consistent with previous glasshouse studies, the selected tropical tree species exhibited significantly lower Vcmax values than their temperate counterparts. Importantly, I showed, for the first time, that the Vcmax estimated on the basis of intercellular CO2 partial pressure was equivalent to that on the basis of chloroplastic CO2 partial pressure, when using appropriate Michaelis-Menten constants for CO2 and O2. Thus, low mesophyll conductance in tropical moist forest is unlikely to account for the low estimates of Vcmax found in the Peruvian field work study. Finally, mechanisms underpinning development of photosynthesis in tropical moist forest trees, which include ontogenetic changes in leaf anatomy, and mesophyll and stomatal conductances, were examined. Key components of photosynthesis such as Vcmax, maximum electron transport rate and chlorophyll content increased synchronously during expansion, accompanied by development of leaf internal structures such as intercellular air spaces and mesophyll cells. The balance between photosynthetic carbon uptake and respiratory release changed dramatically during leaf development, reflecting a two-fold decline in area-based rates of respiration in expanding leaves as photosynthesis became fully functional. The dataset presented in my PhD thesis adds to the growing number of empirical estimates highly needed by the photosynthetic modelling communities, and validates the accuracy of Vcmax estimation using biochemical approaches. Collectively, my study is expected to contribute towards better understanding and representation of Vcmax in tropical forests.
