Book Description
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.

Book Description
India has a vast landmass of 328 million hectares, extending from the tropics to the alpine regions, rich wetlands to deserts, islands, long coastline to Western and Eastern Ghats and the high Himalayas. It has equally rich and diverse plant diversity, with over 47,000 species that are already documented. Because of the large population dependence on these plants, expansion of agriculture, urbanization and development efforts, many species are threatened too. Some of the issues concerning plant diversity in India are unique to the country. Taxonomic and floristic studies on all major groups have been carried out but the information is scattered in research papers and regional/local floras, manuals and monographs. This volume intends to bridge this gap. Nine of the thirteen chapters of this volume deals with different plant groups extending from algae to angiosperms and allied groups such as bacteria, fungi, lichens, and myxomycetes. There are chapters dealing with topical issues in global context on biodiversity with special reference to India such as climate change and its impact on biodiversity, crop diversity, and tradomedicalism. Each chapter is written by author(s) specialising on the particular group and having long experience of research in it. Each chapter includes not only distribution and diversity but also major researches, economic uses and conventional human interactions. Lacunae in current knowledge are also pinpointed. The book provides information on ecosystem diversity, flora of special sensitive regions (mangroves, wetland, and coral reefs), and on policies and strategies being adopted for in situ and ex situ conservation.

Book Description
This plant book aims to help identify flowering plants to genus and family level anywhere in the world. In 2014 there were very few available works which were both comprehensive and up-to-date for all the flowering plants families and genera of the world. The Flowering Plants Handbook is an easy to use identification guide to the worlds flowering plants designed for both specialists and non-specialists and from beginner to expert. The book contains descriptions of all currently recognised flowering plant families, morphological notes for 6656 genera (all current genera for 398/413 families) and over 3000 images and illustrations. Flowering plants can be identified using the book to family and much of the world's generic diversity in four 'easy' steps. Some plants will be identified correctly quickly, whilst others may require some retracing of steps and take a little more time. The advantage of this book is that it helps the user learn about the classification system and plant diversity during the identification process. This work was compiled and developed using the living, library and herbarium collections at the University of Aberdeen, Royal Botanic Gardens, Edinburgh and Royal Botanic Gardens, Kew.

Book Description
In coastal aquifers, saltwater intrusion may cause serious consequences in terms of both environmental and economic impacts. An attempt has been made in the present study to elucidate the quality of groundwaterin the study area in terms of the chemical parameter change due to the seasonal variation of water level. The present study deals with the physio-chemical characteristics of groundwater quality in Nagapattinam district.The study area showed generally similar hydrochemical characteristics slightly higher level of Cl-, Na+, and EC was observed. Based on the Cl- , Na+ and EC data, the groundwater falls within high salinity.

Book Description
There are many books on Ecological and Biodiversity modeling is available at global level. The present academic book can anticipate different level of preparedness and logical interventions emphasis on the formulation of real environmental data sets. Befitting soothe of the book is not initiatory, it venture various statistical and mathematical models induction for solving real world problems of ecological imbalance. Reader is presuming to know the paramount or vital role of recent analytical tools and data base management of ecology. An expeditious of the text book can trace salient objectives and practical applicability to insight what mechanisms are convenient and more significant, when they should be applied in real life. Numerous illustrations are accord to clarify the use of latest statistical techniques and to substantiate what conclusions can be made at the right time for implication of environmental policy at global level. Ongoing text book is more benevolent for post graduates, research scholars, Doctoral, Post-doctoral degree scholars and academicians etc. Nonetheless, post graduates and research Scholars will easily holdout the various analytical methods to enable for the compilation of high dimensional ecological datasets (Big data) and also to know the techniques of econometric modeling on tribal. Although, the book scantly discussed on the very few topics, each topic thrash out functional relationship between 'NICHE' and derivatives of various ecosystem. The current academic book intends to be advance, used as a textbook for post graduate students in ecology, botany, wildlife, plant and animal genetics, but it can also be used by researchers as a reference book. For advanced readers, they can opt for read any particular chapters as they desire.

Book Description
Medicinal plant research is an evergreen subject. There is a tremendous increase in popularity of herbal medicine in traditional medicine, ethnomedicine, modern medicine and as over the counter food supplements. Even after this increased demand, supply is neither uniform nor assured as most of these plants are collected from wild. In developing countries of tropical and subtropical regions where majority of herbal drugs are produced, this is not organised sector making it vulnerable to several malpractices, hence standardization of all aspects required. This has also negative impact on biodiversity and conservation of plants as well as supply of uniform material. This book is aimed to provide up to date information about sustainable use of selected medicinal plants, their active ingredients and efforts made to domesticate them to ensured uniform supply. Development of agrotechnology, biotechnology and cultivation practices using conventional and non-conventional methods are presented. Where these efforts will lead the medicinal plant research and future perspective are discussed. The chapters are written by well recognised group leaders in working in the field. The book contains topics on general biology of medicinal plants, their sustainable use and, cultivation and domestication efforts. A uniform chapter structure has been designed to keep consistency. The book will be useful for academicians, agriculturists, biotechnologists and researcher, and industries involved in manufacturing herbal drugs and supplementary products.
