Plant classifications are based on morphological characters and it is difficult, particularly in small plants and grasses, to identify these below generic level on the basis of these characters using a dissecting microscope. Plant species have intra- and inter-specific variation in secondary metabolites which can be utilized as marker compounds for identification and classification of plants. Secondary metabolites are produced as a result of primary metabolism and the production of these compounds not only involves several genes but also it is an energy dependent process. Hence these products cannot be considered as insignificant for the plant and the environment. Modern tools of molecular biology and secondary metabolites present in them can definitively decide about classification of plants. Absence of correct identification of plant is associated to many problems of resource utilization. Due to wide availability of these tools, interest has revived in systematics and correct classification of plants based on these parameters for their sustainable utilization and resource management. The purpose of this book is to assess the potential of phytochemical and molecular tools in the systematic and classification of plants. The topics covered include species concept, barcoding and phylogenetic analysis, chemotaxonomy use of polyketides, carotenes, cuticular wax, volatile oils, biodiversity of corals, metazoans, Ruta and Echinocereus. It provides comprehensive and broad subject-based reviews, useful for students, teachers, researchers, and all others interested in the field. The field has been kept wide and general to accommodate the wide-ranging topics. This book will be useful to agriculturists, chemists, botanists, industrialists, and those involved in planning of crop plants.

Analysis of plant diversity aims to understand the organisation and the variability of biological populations within ecosystems. In classical analysis, individual plants are firstly identified on the basis of morphological/cytological parameters, then biodiversity is evaluated tacking into account presences/absences, abundances and densities of plants. Although morphological parameters are easily accessible, they provide limited precision on the differentiation between individuals that share a high similarity. This book provides illustrations on different chemotaxonomical criteria helping to understand complex structures of plant diversity. It focuses particularly on the chemotaxonomic usefulness of phenolic compounds (phenylpropanoids, flavonoids, etc.) and sesquiterpenes in analysis of plant chemical polymorphisms at different systematic levels (from family to variety and chemotype via genus and species).

The depletion of biodiversity is an alarming problem all over the country. The world conservation strategy suggests that the initial effort of biodiversity conservation should aim at establishment and maintenance of a network of protected area systems by making policy changes involving local people in the protected areas management and mobilising financial resources for their conservation and protection. The problem of biodiversity conservation has become a global issue. It is being realised that forests existing in a country is not a resource just for that country, but for the whole of the world. The Amazoian Rain Forests have been called the Lungs of the World as they serve to purity of the global atmosphere by release of oxygen and absorption of Pollutants. The rate of deforestation is several times higher in the developing countries than the developed countries, as the forests are being felled to generate funds and space for development. The total number of species in the world is estimated to be around 5 to 30 million but of which about 1.4 millions species have been described. The total number of plant species in India is estimated to be about 45,000 (15,000 flowering plants, 64 gymnosperms, 2843 bryopthes, 1042 pteriodophytes, 1940 lichans and 23,000 fungi). Nearly 4900 of those species are endemic to India out of which 1500 are highly threatened (MOEF, 1994).

Taxonomy is the theory and practice of classification, and chemotaxonomy incorporates the principles and procedures involved in the use of chemical evidence for classificatory purposes. Chemical Systematics is the study of the chemical variation in a diversity of organisms, and of their relationships. This book does not aim to give accounts of the systematics of any group of plants but rather to introduce and illustrate the ways in which chemical data may be used with profit to taxonomists.

Despite acknowledgment that loss of living diversity is an international biological crisis, the ecological causes and consequences of extinction have not yet been widely addressed. In honor of Edward O. Wilson, winner of the 1993 International Prize for Biology, an international group of distinguished biologists bring ecological, evolutionary, and management perspectives to the issue of biodiversity. The roles of ecosystem processes, community structure and population dynamics are considered in this book. The goal, as Wilson writes in his introduction, is "to assemble concepts that unite the disciplines of systematics and ecology, and in so doing to create a sound scientific basis for the future management of biodiversity."

View a collection of videos on Professor Wilson entitled "On the Relation of Science and the Humanities" "In the Amazon Basin the greatest violence sometimes begins as a flicker of light beyond the horizon. There in the perfect bowl of the night sky, untouched by light from any human source, a thunderstorm sends its premonitory signal and begins a slow journey to the observer, who thinks: the world is about to change." Watching from the edge of the Brazilian rain forest, witness to the sort of violence nature visits upon its creatures, Edward O. Wilson reflects on the crucible of evolution, and so begins his remarkable account of how the living world became diverse and how humans are destroying that diversity. Wilson, internationally regarded as the dean of biodiversity studies, conducts us on a tour through time, traces the processes that create new species in bursts of adaptive radiation, and points out the cataclysmic events that have disrupted evolution and diminished global diversity over the past 600 million years. The five enormous natural blows to the planet (such as meteorite strikes and climatic changes) required 10 to 100 million years of evolutionary repair. The sixth great spasm of extinction on earth--caused this time entirely by humans--may be the one that breaks the crucible of life. Wilson identifies this crisis in countless ecosystems around the globe: coral reefs, grasslands, rain forests, and other natural habitats. Drawing on a variety of examples such as the decline of bird populations in the United States, the extinction of many species of freshwater fish in Africa and Asia, and the rapid disappearance of flora and fauna as the rain forests are cut down, he poignantly describes the death throes of the living world's diversity--projected to decline as much as 20 percent by the year 2020. All evidence marshaled here resonates through Wilson's tightly reasoned call for a spirit of stewardship over the world's biological wealth. He makes a plea for specific actions that will enhance rather than diminish not just diversity but the quality of life on earth. Cutting through the tangle of environmental issues that often obscure the real concern, Wilson maintains that the era of confrontation between forces for the preservation of nature and those for economic development is over; he convincingly drives home the point that both aims can, and must, be integrated. Unparalleled in its range and depth, Wilson's masterwork is essential reading for those who care about preserving the world biological variety and ensuring our planet's health.
