Available in PDF, EPUB and Kindle. Book excerpt: The Western Australian jarrah forest is unique, contammg some of the most beautiful flora in the world, more than 100 species of birds and some 50 mammals indigenous to this State. This book "The Jarrah Forest - A Complex Mediterranean Ecosystem" is a collection of scholarly essays on every known aspect of the northern part of the jarrah forest extending from south of Collie to the Avon River. All of the work has been researched by members of tertiary institutions, the private sector and government instrumentalities and was prepared expressly for this book. In the list of contributors are the names of many Western Australians who are in the forefront of their particular field. The book will be a very important reference work for senior secondary schools and tertiary institutions in Western Australia for many years to come. Additionally, it will have wide appeal to all interested in forestry management, both in Australia and overseas. I should like to express my appreciation for the efforts of all those involved in the conception and planning of this most valuable book. Perth, August 1988 Peter Dowding LL.B. M.L.A.

Download or read book Root Morphology, Photosynthesis, Water Relations and Development of Jarrah (Eucalyptus Marginata) in Response to Soil Constraints at Restores Bauxite Mines in South-western Australia written by Christopher Szota and published by . This book was released on 2009 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bauxite mining is a major activity in the jarrah (Eucalyptus marginata Donn ex Sm.) forest of south-western Australia. After mining, poor tree growth can occur in some areas. This thesis aimed to determine whether soil constraints, including reduced depth and compaction, were responsible for poor tree growth at low-quality restored bauxite mines. In particular, this study determined the response of jarrah root morphology, leaf-scale physiology and growth/development to soil constraints at two contrasting (low-quality and high-quality) restored bauxite-mine sites. Jarrah root excavations at a low-quality restored site revealed that deep-ripping equipment failed to penetrate the cemented lateritic subsoil, causing coarse roots to be restricted to the top 0.5 m of the soil profile, resulting in fewer and smaller jarrah trees. An adjacent area within the same mine pit (high-quality site) had a kaolinitic clay subsoil, which coarse roots were able to penetrate to the average ripping depth of 1.5 m. Impenetrable subsoil prevented development of taproots at the low-quality site, with trees instead producing multiple lateral and sinker roots. Trees in riplines, made by deep-ripping, at the high-quality site accessed the subsoil via a major taproot, while those on crests developed large lateral and sinker roots.

Download or read book Water Use, Ecophysiology and Hydraulic Architecture of Eucalyptus Marginata (jarrah) Growing on Mine Rehabilitation Sites in the Jarrah Forest of South-western Australia written by Timothy Michael Bleby and published by . This book was released on 2003 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: [Truncated abstract. Please see the pdf format for the complete text. Also, formulae and special characters can only be approximated here. Please see the pdf version for an accurate reproduction.] This thesis examines the water use, ecophysiology and hydraulic architecture of Eucalyptus marginata (jarrah) growing on bauxite mine rehabilitation sites in the jarrah forest of south-western Australia. The principal objective was to characterise the key environment and plant-based influences on tree water use, and to better understand the dynamics of water use over a range of spatial and temporal scales in this drought-prone ecosystem. A novel sap flow measurement system (based on the use of the heat pulse method) was developed so that a large number of trees could be monitored concurrently in the field. A validation experiment using potted jarrah saplings showed that rates of sap flow (transpiration) obtained using this system agreed with those obtained gravimetrically. Notably, diurnal patterns of transpiration were measured accurately and with precision using the newly developed heat ratio method. Field studies showed that water stress and water use by jarrah saplings on rehabilitation sites were strongly seasonal: being greatest in summer when it was warm and dry, and least in winter when it was cool and wet. At different times, water use was influenced by soil water availability, vapour pressure deficit (VPD) and plant hydraulic conductance. In some areas, there was evidence of a rapid decline in transpiration in response to dry soil conditions. At the end of summer, most saplings on rehabilitation sites were not water stressed, whereas water status in the forest was poor for small saplings but improved with increasing size. It has been recognised that mature jarrah trees avoid drought by having deep root systems, however, it appears that saplings on rehabilitation sites may have not yet developed functional deep roots, and as such, they may be heavily reliant on moisture stored in surface soil horizons. Simple predictive models of tree water use revealed that stand water use was 74 % of annual rainfall at a high density (leaf area index, LAI = 3.1), high rainfall (1200 mm yr-1) site, and 12 % of rainfall at a low density (LAI = 0.4), low rainfall (600 mm yr-1) site, and that water use increased with stand growth.

This book was released on 2012-12-06 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the majority of the presentations of the Second International Symposium on the Biology of Root Formation and Development that was hcld in Jerusa lem, Israel, June 23---28, 1996. Following the First Symposium on the Biology of Adventi tious Root Formation, held in Dallas. USA, 1993, we perceived the need to include all kinds of roots, not only the shoot-borne ones. The endogenous signals that control root formation. and the subsequent growth and development processes, are very much alike, re gardless of the sites and sources of origin of the roots. Therefore, we included in the Sec ond Symposium contributions on both shoot-borne (i.e., adventitious) roots and root-borne (i.e., lateral) roots. Plant roots have remained an exciting and an intriguing field of sciencc. During thc years that followed the first symposium, an exceptional proliferation of interest in root biology has developed, associated with the intensive research activity in this field and the contemporary developments in the understanding of root function and development. New methods have been applied, and old ideas and interprctations werc rccxamined. Alto gether, it became necessary to update our viewpoints and to expand them.

Available in PDF, EPUB and Kindle. Book excerpt: Plantations of a wide range of tree species have assumed an important place in our world, providing wood for industry, fuelwood and animal fodder, protection from adverse environments and for the soil, as well as amenity and aesthetically pleasing landscapes. silvicultural knowledge of this particular branch of forestry first developed in Europe more than two centuries ago but in many parts of the world is still in a process of rapid evolution as more and more plantations are established to meet specific needs. The first exotic tree species to be established in plantations in my own country were planted more than a century ago and, likewise, New Zealand has a long history of planting. Both countries have developed a vigorous and innovative approach to plantation practice, soundly based initially on European experience but gradually modified to meet the challenges of new environments, new markets, and changed economic circumstances. This book on plantation silviculture was begun some years ago when the lack of a suitable undergraduate text for teaching purposes became apparent. The present text is aimed essentially at this audience. Although I have drawn heavily on the experience of Australia and New Zealand, the principles outlined are applicable anywhere in the world where plantations are being grown and tended, from the United States and Scandinavia to India, South Africa or Brazil. The text should also serve as a useful reference to advanced students and practicing foresters, with the reference list providing an introduction to the literature on this subject.

Download or read book Mediterranean-Type Ecosystems written by F.J. Kruger and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: The theory of ecological convergence underlies the biogeographers' maps of world biome-types. It also determines the degree to which ecological principles, derived from research on particular populations, communities or ecosystems, are generally valid, and hence also to what extent resource management principles are general. To quote Di Castri and Mooney (1973): "In effect, in order to assess the transfer of technology, it is essential to know to what extent information acquired from studying one particular ecosystem is applicable to another ecosystem of the same type but situated in a different location. " The five relatively small, isolated, mediterranean-climate zones of the earth, each with its distinct fauna and flora, have provided the ideal testing grounds for this theory. A heritage of precisely focused ecosystems research has resulted, beginning with the international comparative analyses conducted by Specht (l969a, b) but with antecedents in earlier studies in South Australia (Specht and Rayson 1957, Specht 1973). Cody and Mooney (1978) reviewed the information available at the time for the four zones excepting Australia and concluded that the arrays of strategy-types to be found among the different biotas were so similar that they could be explained only in terms of the convergence hypothesis; nevertheless, evident differences in community organization and dynamics, especially phenol ogy, required closer study of resource availability and resource-use patterns to better explain relations between form and function overall, and to assess the degree of convergence at higher levels of organization than the population.

Book excerpt: Water Deficits and Plant Growth, Volume VI: Woody Plant Communities focuses on the water relations of woody plants in a community context. Organized into eight chapters, this book begins with a quantitative overview of sources of water available to woody plants. Separate chapters follow that discuss the water relations of coniferous, temperate hardwood, and tropical and subtropical forests and woodlands; apple and citrus orchards; closely related woody plants; and tea plantations. For each of these plant communities, emphasis is placed on hydrological cycles; water use and transpiration; absorption of water; and effects of environmental factors on soil and plant water balance. The effects of water deficits on physiological processes; vegetative and reproductive growth; yield of harvested products; drought resistance; and cultural practices affecting plant water balance and yield are also emphasized in this book. This volume will be useful to both researchers and those involved in the practice of growing woody plants for wood and fruit crops and for esthetic values.

This book was released on 2013-03-14 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last two decades technological advances in isotope ratio mass spectrometry have been very rapid, opening up new possibilities for analysis of biological and environmental materials. The new instrumentation has facilitated faster analysis of samples via automated sample preparation and multi-isotope analysis of single samples, resulting in considerable cost savings, and enabling access to isotope analysis for many more researchers. These changes are reflected in the rapidly growing international literature on stable isotopes. While there have been some excellent books and review papers aimed at interpreting isotope signals in biology and environmental science, there have been fewer attempts to provide practical tools for researchers making forays into this exciting new arena. This book aims to address this inadequacy by providing a set of practical guidelines for the application of a range of novel and well proven stable isotope techniques to the fields of plant physiological ecology, agriculture, marine ecology and palaeoecology. The book is the outcome of a weeklong workshop held under the auspices of the Cooperative Research Centre for Legumes in Mediterranean Agriculture (CLIMA 1992 - 2000) at The University of Western Australia and the CSIRO Floreat Laboratories, Perth, Western Australia, in February 1999. The workshop was designed to provide practical tools and experiences for researchers and students concerned with how one goes about using stable isotopes in field investigations.

This book was released on 2012-12-06 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Used by humans since ancient times, evergreen oak forests still cover extensive mountain areas of the Mediterranean Basin. These broadleaved evergreen forests occupy a transitional zone between the cool-temperate deciduous forest biome and the drier Mediterranean pine forests and shrublands. Slow growing and casting a deep shade, the sclerophyllous holm oak (Quercus ilex) absolutely dominates the closed canopy of many Mediterranean evergreen oak forests. This is a synthesis of 20 years of research on the structure, function, and dynamics of holm oak forests in two intensively studied experimental areas in Spain. By combining observational measurements at the leaf, tree, plot, and catchment scales with field experiments and modelling, the authors explore how these forests cope with strong water limitation and repeated disturbances.
