The present study is an attempt to study of some selected water bodies in Jhunjhunu district. The study started with survey and collection of water sample periodically to enumearate the algal diversity in water bodies and analysis of the physico-chemical properties of water. The present study also carried out with survey and collection of five aquatic angiospermic plants viz. Lemna minor, Spirodela polyrhiza, Wolffia globosa, Ceratophyllum demersum and Hydrilla verticillata from selected water bodies of Jhunjhunu district. Various ecophysiological parameters of these plants were studied in detail. The present thesis begins with a brief introduction of the Biodiversity (Chapter 1), which includes phycobiodiversity and aquatic angiospermic diversity, medicinal properties, loss of diversity, conservation of diversity and review of literature. Chapter 2 gives information on material and methods. The detailed of selected sites are also presented in this chapter. Chapter 3 include the phycodiversity, aquatic angiospermic diversity and ethnomedicinal diversity of some selected water bodies of Jhunjhunu district. Chapter 4 gives an account on the ecophysiological parameters of the selected aquatic angiospermic plants comprising monthly fluctuations in leaf pigments, proline accumulation and sugars. Chapter 5 includes an account on the properties of water parameters such as temperature, pH, alkalinity, hardness, chloride, total dissolved solid and dissolved oxygen. Chapter 6 gives information about Biotic interference in selected water bodies of Jhunjhunu district. Chapter 7 includes discussion on the whole present work. Chapter 8 and 9 are of summary and References, respectively. Finally the salient outcome of the entire work is profusely illustrated with relevant coloured photographs, numerous tables and graph to support the experimental observations. It is eamestly hoped that the present piece of work will provids some novel informtion to a common man as well as to researches for better understanding on biodiversity and ecophysiological studies of these aquatic angiospermic plants and water parameters at their supportive localities.
