Silica bodies from over 200 species of Neotropical grasses comprising 80 different genera from all currently recognized subfamilies have been isolated from plant tissue and have been described. Silica-body shapes are significant at varying taxonomic levels, from the family to the genus. The Bambusoideae, especially, contribute large numbers of tribal- and genus-specific forms. Significant correlations are found between phytolith shape and the source plant's taxonomic relationships and postulated phylogeny. Disarticulated short-cell phytoliths occurring in ancient soils and sediments can be used to make identifications of certain taxa in the Poaceae below the level of family. Silica bodies observed in fossil grasses may elucidate the evolutionary history of the Poaceae.

Comprising 20 scientific contributions to the archaeology of Guadeloupe, French West Indies, this volume places the latter Caribbean Island in the spotlight by presenting the results of four contemporaneous archaeological sites. By means of these four sites, this book explores a variety of issues contemplating the transition from the Early to the Late Ceramic Age in the Lesser Antilles. Studies of pre-Columbian material culture (ceramics, lithics, faunal, shell and human bone remains) are combined with additional microanalyses (starch and phytolith analyses, micromorphology and thin sections) to sort out the processes that triggered the cultural transition just before the end of the first millennium CE. The multidisciplinary approach to address these sites Saladoid shows the current state of affairs on project-led archaeology in the French West Indies and should be of great value to both researchers and students of Caribbean archaeology, material cultures, zooarchaeology, environmental studies, historical ecology, and other related fields.

Grasses: Systematics and Evolution is a selection of the very best papers from the Proceedings of the Third International Symposium on Grass Systematics and Evolution held in Sydney, Australia in 1998. The papers represent some of the leading work from around the world on grasses and include reviews and current research into the comparative biology and classification. All 41 papers have been peer-reviewed and edited.

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.

This impeccably-researched volume skillfully reports and discusses advances in phytolith research, addressing in particular the use of phytoliths for deciphering fundamental issues in earth science and human history. Comprising thirty reviews and original papers, findings are presented in the following five sections: · phytoliths in palaeoclimatology and palaeoecology · phytoliths, diet and health · archaeological structures, ancient agricultures and palaeoethnobotany · methodology, taxonomy and taphonomy · soil-plant interaction.

Silicon is among the most abundant elements on earth. It plays a key but largely unappreciated role in many biogeochemical processes, including those that regulate climate and undergird marine food webs. The Silicon Cycle is the first book in more than 20 years to present a comprehensive overview of the silicon cycle and issues associated with it. The book summarizes the major outcomes of the project Land-Ocean Interactions: Silica Cycle, initiated by the Scientific Community on Problems of the Environment (SCOPE) of the International Council of Scientific Unions (ICSU). It tracks the pathway of silicon from land to sea and discusses its biotic and abiotic modifications in transit as well as its cycling in the coastal seas. Natural geological processes in combination with atmospheric and hydrological processes are discussed, as well as human perturbations of the natural controls of the silicon cycle.

This third volume in the Developments in Paleoenvironmental Research series deals with the major terrestrial, algal, and siliceous indicators used in paleolimnology. Other volumes deal with the acquisition and archiving of lake sediment cores, chronological techniques, and large-scale basin analysis methods (Volume 1), physical and geochemical parameters and methods (Volume 2), zoological techniques (Volume 4), and statistical and data handling methods (Volume 5). These monographs will provide sufficient detail and breadth to be useful handbooks for both seasoned practitioners as well as newcomers to the area of paleolimnology. Although the chapters in these volumes target mainly lacustrine settings, many of the techniques described can also be readily applied to fluvial, glacial, marine, estuarine, and peatland environments.
