Fertility bryoecology and perennation of mosses. References. The Moss Flora of Rajasthan furnishes the first comprehensive view of the mosses growing in various localities of the state. Floristic studies generally take into account the higher plants growing in an area which from dominant vegetation on the earths surface. Cryptogamic flora has attracted comparatively less attention of the taxonomists. The bryophyta flora of Indian sub continent is very poorly studied except some important studies on the Himalayan region. (jacket) 123 pp.…

Hardcover. Condizione: New. This book presents a comprehensive taxonomic account of the most difficult and largest genus of angiosperm Astragalus of the family Leguminosae in India. Astragalus is chiefly distributed in the cold desert regions of the Himalaya. This is the first revisionary study on the genus in independent India. It is the outcome of extensive field survey and examination of large number of herbarium specimens housed at various herbaria. The present work includes 79 species of Astragalus found in the present political boundary of India. The detail taxonomic account such as nomenclature, description, phenology, habitat, distribution, list of specimens examined etc. have been provided for each species. In addition, taxonomic notes on nomenclature, variation pattern, distribution etc. have also been given wherever found necessary. Large numbers of colour and black and white photographs of the habit of the plants provided in the book further enhanced the quality of the work. All species have been grouped into 28 sections following recent classification. Each section has been briefly characterized and taxonomic keys to the sections and species within the sections have been provided for quick identification. A recently segregated genus from Astragalus, Phyllolobium with four species has also been dealt separately at the end of work for the sake of convenience as people may search these species here due to their long placement in Astragalus. This book would be quite useful for the students of botany, molecular taxonomy, palynology, anatomy etc. to take up the genus for further studies to resolve its complex taxonomy and phylogeny. Some of the species of Astragalus are the source of the commercial gum tragacanth and they are highly medicinal. Astragalus malacophyllus is a well known drug as Rudanti or Rudravanti used for tuberculosis, skin diseases, coughs and blood purifier in India. Astragalus root is also a well known drug in traditional Chinese medicine since ancient time and large numbers of products have been developed on it. Hence, this book will also serve as reference for those who are involved in drug discovery research.'.…

Hardcover. Condizione: New. 1st Edition. The book "Organic Evolution", with several novel features, is comprehensively written with latest advances in the subject and is divided in seven chapters. Chapter 1 of the book describes the environment of primitive earth and how it was essential for the origin of first life form. Chapter 2 includes evolutionary theories and supporting evidences in favour of evolution. The role of population genetics in evolution of gene pools of population is in Chapter 3. The concept of species and modes of speciation, how new species originates and how much genetic change is required for speciation is discussed in Chapter 4. Chapter 5 provides the essential information needed to understand molecular evolution and how molecules are reliable tools for molecular systematics and in reconstruction of phylogenies. Chapter 6 of the book describes vertebrate diversity and vertebrate evolution primarily focusing on Primates and the evolution of Homo sapiens. Finally, Chapter 7 is about the origin and evolution of Angiosperms. The language and contents of this book are made so simple and easy that even a student with a minimal knowledge of Life Sciences will be able to understand the essence of evolution.This book has been designed mainly to provide the most fundamental and updated knowledge of the subject to undergraduate and postgraduate students in various streams of Life Sciences- Botany, Zoology, Biotechnology, Microbiology, Biochemistry, Agriculture etc; of Indian Universities. Besides this book will be beneficial to student's preparing for CSIR NET Life Sciences, GATE Life Sciences, ICMR Life Sciences, IAS, IFS and other State Civil service examinations. (jacket).…

Hardbound. Condizione: As New. New. Contents Preface. Abbreviations. 1. Review of literature. 2. Study area. 3. Origin of Bryophyte. 4. Morpho taxo anatomical studies. 5. Bryoecology and distribution. 6. Fertility perennation and dissemination. Bibliography. Index. Bryophytes are a diverse and distinct group of primitive plants with about 25 000 species distributed the world over making in the second largest group of land plants. They are considered as amphibians of plant kingdom owing to their presence to aquatic and other moist habitats. Bryophytes are characterized by the absence of vascular tissues and having a unique life as Buxbaumia. Though considered as Lilliputains of plant kingdom Bryophytes have achieved the greatest gametophytic diversity. The group includes three distinct lineages viz. liverwots hornwots and mosses. The present study provides the first hand consolidated account of Bryophytes of North Konkan which includes detailed illustration taxonomic account ecology and phytogeographical consideration of 100 species of Bryophytes belonging to 37 genera distributed over 24 families. The North Konkan is characterized by Sandy splits intruding into mud flats and wider creeks close to the sea and by low coastal range separated by longitudinal valleys away from the coast moreover with the Thalghat and Bhorghat gaps in the Sahyadric the North Konkan is actively linked with the vast real western gateway of India. Floristic study of Bryphytes has received little attention in India in general and North Konkan Coast in particular through this groups forms the largest group of land plants in term of species not much attention has been paid of Bryophytes of North Konkan except the work of Dabhade (1966) Menon (1992) Palav (1994) and Patil (1996). 326 pp.…
