Book Description
The Göttingen conference Systematics 2008 is the first joint meeting of the Gesellschaft für Biologische Systematik (GfBp. and the German Botanical Society, section Biodiversity and Evolutionary Biology (DBG), being the 10th Annual Meeting of the GfBS and the 18th International Symposium Biodiversity and Evolutionary Biology of the DBG. The conference programme covers biological systematics in the widest sense and provides ample opportunities for oral and poster presentations on new advances in plant, animal and microbial systematics. This volume brings together the abstracts of invited speaches from the plenary sessions on Progress in Deep Phylogeny, Speciation and Phylogeography, and New Trends in Biological Systematics as well as those of submitted talks and poster sessions.

Book Description
"Taxonomists dealing with fruit crops have rated systematic pomology as an advanced horticultural subject and takes into consideration the basic aspects of taxonomy i.e. identification, naming of fruit plant species and varieties, besides, placements or logical classification of each fruit type under specific units of classification. For sound horticultural systematic knowledge primarily those of taxonomy, morphology, genetics, cytology and plant breeding is essential. For good reading material it is essential for systematic pomologists to use information of the associated sciences with appropriate explanations and applications. The present work provides elementary knowledge to the students who have started studying systematic pomology and covers: Introduction (three sub-heads) presents the more academic elements of taxonomy related to the theories, hypothesis, basic principles pre-requisite of systematics which are required for a minimum working knowledge of systematic pomology. The detail regarding general origin and distribution, flower and fruit structure is given so that students with this background knowledge are in a position to cope with problems related both to varietal descriptions and testing. Significance of systematic pomology to varietal improvement, new variety sources and methods of synthesis are detailed. The section 1-4 comprises of systematic enumeration of 58 fruits, discussed under the heads of tropical and subtropical, small fruits, nut fruits and temperate fruits. Each crop covers in detail the historical background, origin, distribution and uses, pomological traits of fruit, important species and cultivars and line drawings of flowers and fruits structures. List of cultivars is restricted to popular cultivars as the cultivation status is ever changing. The glossary and annexures are designed with thrust on clarity and brevity. The annexures provide detailed information of fruit crops, fruit types, genera, species and tribes, their number and status in fruit crop families. Botanical terms chart provides morphological description of leaf, floral structure and form, inflorescence root and rootstock for easily understanding by the readers."

Book Description
Although they are relative latecomers on the evolutionary scene, having emerged only 135?170 million years ago, angiosperms—or flowering plants—are the most diverse and species-rich group of seed-producing land plants, comprising more than 15,000 genera and over 350,000 species. Not only are they a model group for studying the patterns and processes of evolutionary diversification, they also play major roles in our economy, diet, and courtship rituals, producing our fruits, legumes, and grains, not to mention the flowers in our Valentine’s bouquets. They are also crucial ecologically, dominating most terrestrial and some aquatic landscapes. This fully revised edition of Phylogeny and Evolution of the Angiosperms provides an up-to-date, comprehensive overview of the evolution of and relationships among these vital plants. Incorporating molecular phylogenetics with morphological, chemical, developmental, and paleobotanical data, as well as presenting a more detailed account of early angiosperm fossils and important fossil information for each evolutionary branch of the angiosperms, the new edition integrates fossil evidence into a robust phylogenetic framework. Featuring a wealth of new color images, this highly synthetic work further reevaluates long-held evolutionary hypotheses related to flowering plants and will be an essential reference for botanists, plant systematists, and evolutionary biologists alike.

Book Description
The culmination of more than fifty years of research by the foremost living expert on plant classification, Diversity and Classification of Flowering Plants is an important contribution to the field of plant taxonomy. In the last decade, the system of classifying plants has been thoroughly revised. Instead of describing every individual family, Takhtajan includes descriptions in keys to families, which he calls "descriptive keys." The advantage of descriptive keys is that they give both the characteristic features of the families and their differences. The delimitation of families and orders drastically differs from the one accepted by the Englerian school and from the one accepted in Arthur Cronquist's system. Takhtajan favors the smaller, more natural families and orders, which are more coherent and better-defined, where characters are easily grasped, and which are more suitable for information retrieval and phylogenetic studies, including cladistic analysis (because it reduces polymorphic codings).

Book Description
This volume is the first in theAdvances in Archaeological and Museum Science series sponsored by the Society for Archaeological Sciences. The purpose of this biennial series is to provide summaries of advances in closely defined topics in archaeometry, archaeological science, environmental archaeology, preservation technology and museum conservation. The Society for Archaeological Sciences (SAS) exists to encourage interdisci plinary collaboration between archaeologists and colleagues in the natural and physical sciences. SAS members are drawn from many disciplinary fields. However, they all share a common belief that physical science techniques and methods constitute an essential component of archaeological field and laboratory studies. The General Editors wish to express their appreciation to Renee S. Kra and Frances D. Moskovitz of Radiocarbon for their special expertise and assistance in the production of this volume. We also appreciate the contribution of the two reviewers for their excellent comments and suggestions. The General Editor responsible for undertaking the development of this volume was R. E. Taylor.

Book Description
"The book strikes a balance between classical fundamental information and the recent developments in plant systematics. Special attention has been devoted to the information on botanical nomenclature, identification and phylogeny of angiosperms with numerous relevant examples and detailed explanation of the important nomenclatural problems. An attempt has been made to present a continuity between orthodox and contemporary identification methods by working on a common example. The methods of identification using computers have been further explored to help better online identification. The chapter on cladistic methods has been totally revised, and molecular systematics discussed in considerable detail."--Jacket.
