Download or read book An Introduction to Bryophyta written by Rashid A. and published by Vikas Publishing House. This book was released on 1998 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: This endeavour is aimed to be comprehensive and innovative. It covers the entire course of reading in Bryology. After a brief Introduction, there is an account of array of diversity and development of Bryophytes. In three chapters on Liverworts, Hornworts and Mosses, one can find an illustrated and concise account of all representative types. It is followed by comparative morphology. In two chapters on Gametophyte and Sporophyte are unravelled the elements of unity in diversity. Due emphasis has been given to experimental studies. In five chapters are traced the events of life cycle; Spore germination, Protonema differentiation and Gametophyte initiation, Sexuality and Sporophyte development, Regeneration, and Alternation of generations. Experimental studies – a backbone of this book – are not only interesting in a class room but informative to decipher different aspects of differentiation. Finally, there is food for thought in chapters on Cytogenetics and Evolution, and Origin and Fossil History. At the end is an extensive bibliography of old and new Literature, for further reading.

Download or read book Biology of Bryophytes written by R. N. Chopra and published by New Age International. This book was released on 2005 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Study Of Bryophytes Is No Longer Confined To Their Morphology, Anatomy, Life-History, And Phylogenetic Considerations. In Recent Years There Has Been An Increasing Emphasis On Investigations Concerning The Ultrastructure, Reproductive Biology, Ecology, Morphogenesis, Physiology, Biochemistry And Related Aspects Of Bryophytes. These Themes Have Also Rightfully Found Their Place In The Syllabi At All Levels In Most Universities All Over The Globe. However, The Writing Of Texts In This Area Has Lagged Behind. Since The Literature Is Scattered And At Times Not Easy To Reach, There Is An Urgent Need For A Book Which Deals With The Modern Topics Of Bryology. This Volume Is Intended To Fill This Gap. The Authors Have Tried To Make The Compilation Of The Literature As Up-To-Date As Possible, And The References Cited In The Text Have Been Listed At The End Of Each Chapter For Those Interested In More Details. Most Of The Illustrations Have Been Taken From Recent Research Publications And These Have Not Previously Been Included In Any Book As Far As We Aware. Summary Charts And Tables Are Provided At All Appropriate Places.

Download or read book An Introduction to Archegoniate Plants written by Rashid A. and published by Vikas Publishing House. This book was released on with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book covers the entire course on archegoniate plants which is prescribed in the syllabi of different universities for undergraduate students. The presentation is comprehensive and innovative. The book describes different divisions of plant kingdom related to archegoniate plants covering their life cycle, relationship, classification and economic importance. Details of different genera in terms of morphology, anatomy, reproduction and sexuality have been explained with due diagrams. The book also discusses topics like heterospory, seed habit, leaf phylogeny, stellar system, alternation of generations, regeneration in general and special role of germ cells—egg and spore—in life cycle. Experimental studies described in the book highlight the phenomena of apogamy and apospory, their occurrence, induction and alternate role in life cycle. Also given are accounts on micropropagation of gymnosperms and ferns, for commerce and industry. Key Features • Covers Bryophytes, Pteridophytes and Gymnosperms • Loaded with up-to-date information gathered through research results • Supports description through explicit diagrams for clear understanding • Short and to-the-point description so as to cover the entire syllabus within a semester

Download or read book Fern Ecology written by Klaus Mehltreter and published by Cambridge University Press. This book was released on 2010-06-03 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ferns are an integral part of the world's flora, appreciated for their beauty as ornamentals, problematic as invaders and endangered by human interference. They often dominate forest understories but also colonize open areas, invade waterways and survive in nutrient-poor wastelands and eroded pastures. Presented here is the first comprehensive summary of fern ecology, with worldwide examples from Siberia to the islands of Hawaii. Topics include a brief history of the ecological study of ferns, a global survey of fern biogeography, fern population dynamics, the role of ferns in ecosystem nutrient cycles, their adaptations to xeric environments and future directions in fern ecology. Fully illustrated concepts and processes provide a framework for future research and utilization of ferns for graduate students and professionals in ecology, conservation and land management.

Download or read book Meiosis written by Peter Moens and published by Elsevier. This book was released on 2012-12-02 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Meiosis is a monograph focused on meiosis-specific functions. It presents a discussion on the genetic regulations of meiosis and aims to direct readers on future research by reporting a number of studies on progress. The text is divided into four parts and consists of 12 chapters. After an introduction to the meiotic process, the first part of the book narrates the genetic transmission and the evolution of reproduction and parthenogenesis. The second part presents the concepts of recombination, the heteroduplex model, and the genetic control of biochemical events in meiotic recombination. The third part covers the information about the chiasmata and synaptonemal complex, including the Rabl orientation. The text is then concluded by the fourth part that covers the biochemical basis of meiosis. The book is an excellent reference for undergraduate and graduate students in biological courses, specifically in genetics, biochemistry, and cell, developmental, and molecular biology. Lecturers, researchers, and other professionals in the same field will also find this book useful.

This book was released on 1988-07-07 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection of reviews by leading investigators examines plant reproduction and sexuality within a framework of evolutionary ecology, providing an up-to-date account of the field. The contributors discuss conceptual issues, showing the importance of sex allocation, sexual selection and inclusive fitness, and the dimensions of paternity and maternity in plants. The evolution, maintenance, and loss of self-incompatibility in plants, the nature of 'sex choice' in plants, and sex dimorphism are all explored in detail. Specific forms of biotic interactions shaping the evolution of plant reproductive strategy are discussed, and a taxonomically based review of the reproductive ecology of non-angiosperm plant groups, such as bryophytes, ferns, and algae, is presented. Together these studies focus on the complexities of plant life cycles and the distinctive reproductive biologies of these organisms, while showing the similarities between nonflowering plants and the more thoroughly documented flowering species.
