Synopsis This book attempts to give most commonly used methods in environmental science in a single volume. The book can be used as complement to a standard practical manual of ecology and environmental science. The methods elaborated in this volume will be useful for conducting practical classes at undergraduate and postgraduate levels in environmental sciences, biological sciences and agricultural sciences. In addition, this manual will be an important asset for research workers and teachers. The experimental protocols included in this book have been well tested and are in current use in our laboratories. The book is divided into six different chapters viz., air monitoring, limnological analysis, analysis of soil, analysis of vegetation, plant bioassays and ecological adaptations in plant and animals. Procedural details include principle, requirements, procedure and calculation. Major procedures are provided with original reference. All the core procedures are appended with notes which will help users take precautions and predict scientific findings.
