Book excerpt: This volume contains five papers dealing with a wide range of plant, animal, and soil biological topics.Gray and his colleagues describe the origin and spread of the salt marsh grass Spartina anglica. The result of a hybridization at the close of the last century, this genetically uniform species has been extremely successful in its particular niche and has a fascinating biology.Smith stresses the importance of gene-environment interactions in life-history theory in contrast to the resource constraint emphasis of the optimization approach. Experimental approaches to the subject are also discussed.Chanway and his colleagues examine the evidence for the importance of interactions between plants and micro-organisms in the rhizosphere in determining the outcome of plant competition and the establishment of community structure. Despite scarce evidence, real effects meriting further research do seem to exist.Brundrett also deals with an aspect of ecology in the soil. Most plants seem to have mycorrhizal associates and their importance is now widely appreciated. Much has been learned but more research is needed to determine the beneficial or after effects of mycorrhizae in natural systems.Richter and Babar review the diversity of tropical soils. They are in fact much more variable than is often thought, perhaps because too few ecologists are specialists in soils. Clearly, a proper knowledge and understanding of the many soil types is vital to conservation and development work in the tropics. - Serves as the fourth volume under new editorial direction - Presents a broad range of topical papers in ecology - Contains five papers dealing with a wide range of plant, animal, and soil biological topics

High with unbran'ched glabrous culms from stout, scaly rootstocks, long tough leaf-blades and 5 to 20 spikes, forming a terminal panicle. Sheaths crowded below; ligule a ring of hairs; leaf-blades 3 to 12 or 18 dm. Long, 4 to 14 mm. Wide, scabrous on the margins, becoming involute in drying, attenuate into a long Slender tip. Spikes 5 to 10 cm. Long, often on peduncles, 1 to 2 cm. In length, ascending, racemose along the main axis, which is scabrous on the margins, as are also the secondary axes. Spikelets densely imbricate, 12 to 14 mm. Long; empty glumes unequal, strongly aculeolate-scabrous on the rigid keels, the first usually acute, the second long acuminate and more or less awned; flowering glume 7 to 9 mm. Long, glabrous, except for the aculeo late-scabrous midnerve which terminates just below the emarginate or 2-toothed apex. Palea thinner in texture and usually somewhat exceeding the glume.

Available in PDF, EPUB and Kindle. Book excerpt: This volume is the outcome of a modern phylogenetic analysis of the grass family based on multiple sources of data, in particular molecular systematic studies resulting from a concerted effort by researchers worldwide, including the author. In the classification given here grasses are subdivided into 12 subfamilies with 29 tribes and over 700 genera. The keys and descriptions for the taxa above the rank of genus are hierarchical, i.e. they concentrate upon characters which are deemed to be synapomorphic for the lineages and may be applicable only to their early-diverging taxa. Beyond the treatment of phylogeny and formal taxonomy, the author presents a wide range of information on topics such as the structural characters of grasses, their related functional aspects and particularly corresponding findings from the field of developmental genetics with inclusion of genes and gene products instrumental in the shaping of morphological traits (in which this volume appears unique within this book series); further topics addressed include the contentious time of origin of the family, the emigration of the originally shade-loving grasses out of the forest to form vast grasslands accompanied by the switch of many members to C4 photosynthesis, the impact of herbivores on the silica cycle housed in the grass phytoliths, the reproductive biology of grasses, the domestication of major cereal crops and the affinities of grasses within the newly circumscribed order Poales. This volume provides a comprehensive overview of existing knowledge on the Poaceae (Gramineae), with major implications in terms of key scientific challenges awaiting future research. It certainly will be of interest both for the grass specialist and also the generalist seeking state-of-the-art information on the diversity of grasses, the most ecologically and economically important of the families of flowering plants.

Download or read book Polyploidy and Genome Evolution written by Pamela Soltis and published by Springer Science & Business Media. This book was released on 2012-10-03 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polyploidy – whole-genome duplication (WGD) – is a fundamental driver of biodiversity with significant consequences for genome structure, organization, and evolution. Once considered a speciation process common only in plants, polyploidy is now recognized to have played a major role in the structure, gene content, and evolution of most eukaryotic genomes. In fact, the diversity of eukaryotes seems closely tied to multiple WGDs. Polyploidy generates new genomic interactions – initially resulting in “genomic and transcriptomic shock” – that must be resolved in a new polyploid lineage. This process essentially acts as a “reset” button, resulting in genomic changes that may ultimately promote adaptive speciation. This book brings together for the first time the conceptual and theoretical underpinnings of polyploid genome evolution with syntheses of the patterns and processes of genome evolution in diverse polyploid groups. Because polyploidy is most common and best studied in plants, the book emphasizes plant models, but recent studies of vertebrates and fungi are providing fresh perspectives on factors that allow polyploid speciation and shape polyploid genomes. The emerging paradigm is that polyploidy – through alterations in genome structure and gene regulation – generates genetic and phenotypic novelty that manifests itself at the chromosomal, physiological, and organismal levels, with long-term ecological and evolutionary consequences.

Download or read book Mediterranean Type Ecosystems written by George W. Davis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human activities are causing species extinctions at a rate and magnitude rivaling those of past geologic extinction events. Exploring mediterranean-type ecosystems - the Mediterranean Basin, California, Chile, Australia, and South Africa - this volume addresses the question whether biological diversity plays a significant role in the functioning of natural ecosystems, and to what extent that diversity can be reduced without causing system malfunction. Comparative studies in ecosystems that are similar in certain respects, but differ in others, offer considerable scope for gaining new insights into the links between biodiversity and ecosystem functioning.
