Summary:

 Abstract of the Book - Plant Biodiversity. Monitoring, Assessment and Conservation

Plant biodiversity refers to the huge variety of aquatic and terrestrial flora on this earth. Ecologists study plant biodiversity and the environmental factors affecting plant distribution. Plants grow in certain places because environmental factors are suitable for the germination of seeds and continued growth of developing plants. The environmental modifications are the major causes of global species extinction and habitat destruction. The environmental constraints undergoing human modification include levels of nitrogen, phosphorus, calcium, pH, atmospheric CO2, herbivore, pathogen, and predator densities, disturbance regimes, and climate. Extinction would occur because the physiologies, morphologies, and life histories of plants limit each species to being a superior competitor flora particular combination of environmental constraints. Anthropogenic perturbations are one of the most important factors influence plant diversity patterns. Plants are important components of any ecosystem. They are the base of food chain taking energy from the sun and converting it into food for all other organisms through the process of photosynthesis. Plants play a significant role in energy flow and biogeochemical cycling of nutrients between terrestrial and aquatic ecosystems. Plant diversity have been suggested as an important tool for long term monitoring of air, water and soil quality and very well recognized for their bio-indicating values. For the assessment of resilience of aquatic and terrestrial ecosystems, the species richness, biomass based diversity and evenness were found best parameter and indicators. 
Present situation of plant diversity has been greatly influenced by human societies that have depended on them for millennia. The future will depend upon a radical change in national policies on conservation of plant biodiversity, and upon researches which can support the development of appropriate policies. Popular interest in protecting the world’s plant species has intensified during the last 20 years, around the globe. Biological communities that took millions of years to develop are being devastated by human activity. A new multidisciplinary science has evolved to deal with the crises confronting biological diversity is the conservation biology, which has two goals- first, to investigate human impacts on biological diversity and second, to develop practical approaches to prevent extinction of species. Therefore, a regular monitoring and assessment on plant biodiversity is needed to understand the environmental and anthropogenic perturbations and their effects on genetic and species plant diversity. Timely implementation of the different measures obtained after the rigorous researches will effectively contribute in the conservation of plant diversity in botanic gardens, herbaria, museums and gene banks. 
The editors and contributing authors hope that the results of publishing this book will include a practical update on our knowledge on monitoring, assessment and conservation of plant biodiversity in aquatic and terrestrial ecosystems. The book will also cover the different related fields of plant biodiversity on a global scale. The results of this book will leads to new researches, methodologies, discussions and efforts to study the plant biodiversity. Thus, the proposed book is expected to raise the interests of the graduate and post-graduate students, researchers and professionals in botany and plant biodiversity studies.
