The Plant Diversity of Malesia by P. Baas,K. Kalkman,R. Geesink Pdf

Although the only publication with a realistic claim to the title "The plant diver sity of Malesia" is Flora Malesiana itself, we have hesitatingly chosen this title for the present proceedings volume. Past, present and future work on the Flora Malesiana project was the subject of a successful symposium held in August 1989. This book contains only a selection of the papers presented at that meet ing, yet it covers a much greater diversity of themes than just the inventory of botanical diversity. It even goes beyond the boundaries of the vast Flora Malesi ana region in several of its chapters. The role of the founder of the Flora Malesiana Project, Professor C.G.G.J. van Steenis, repeatedly recurs in several chapters; not only as director of and contributor to the project, but also as a pioneer in the fields of Malesian vege tation, conservation and biogeography, and as an enlightened systematist whose ideas and practical recommendations for taxonomic delimitation still largely apply. Botanical information made available in regional and local floras is of vital im portance for applications such as the exploitation of natural forests on a sus tainable yield basis. for establishing gene banks for the benefit of agriculture. forestry and horticulture. and not in the least for nature conservation. Several chapters are devoted to these themes. Floristic studies are also at the basis of the biogeographical essays and vegetation studies included in this book.

Flora of North America: Volume 2: Pteridophytes and Gymnosperms by Flora of North America Editorial Committee Pdf

This second volume of the magnificent compendium exhaustively describes and classifys the ferns, fern allies, and gymnosperms of North America. Covering over two dozen fern and half a dozen gymnosperm families, they survey fern species of both ecological and horticultural importance and review such gymnosperm taxa as the conifers (the dominant trees in many forests as well as important timber plants) and cycads, which display significant evolutionary features. In all, the volume assembles 509 species of ferns and fern allies and infraspecific taxa in 70 genera.

Plant Diversity in India by A.K. Bhatnagar,Rupam Kapoor Pdf

India has a vast landmass of 328 million hectares, extending from the tropics to the alpine regions, rich wetlands to deserts, islands, long coastline to Western and Eastern Ghats and the high Himalayas. It has equally rich and diverse plant diversity, with over 47,000 species that are already documented. Because of the large population dependence on these plants, expansion of agriculture, urbanization and development efforts, many species are threatened too. Some of the issues concerning plant diversity in India are unique to the country. Taxonomic and floristic studies on all major groups have been carried out but the information is scattered in research papers and regional/local floras, manuals and monographs. This volume intends to bridge this gap. Nine of the thirteen chapters of this volume deals with different plant groups extending from algae to angiosperms and allied groups such as bacteria, fungi, lichens, and myxomycetes. There are chapters dealing with topical issues in global context on biodiversity with special reference to India such as climate change and its impact on biodiversity, crop diversity, and tradomedicalism. Each chapter is written by author(s) specialising on the particular group and having long experience of research in it. Each chapter includes not only distribution and diversity but also major researches, economic uses and conventional human interactions. Lacunae in current knowledge are also pinpointed. The book provides information on ecosystem diversity, flora of special sensitive regions (mangroves, wetland, and coral reefs), and on policies and strategies being adopted for in situ and ex situ conservation.

Essays in Evolution and Genetics in Honor of Theodosius Dobzhansky by Max K. Hecht Pdf

It is not often that one has the opportunity to send a public birthday greet ing to a friend and colleague of many years, and to congratulate him on having reached the age of reason. In fact it happens only once, and comes then as a surprise. Surely it was only a few years ago that we sat together at an International Genetics Congress in Ithaca, and only yesterday that we became members of the same department. The eighth floor of Schermerhorn Hall had a north end where the flies were and a south end furnished with mice, and in between, a seminar room and laboratory. There the distances were short and the doors open and the coffee pot busy. But it now appears that yesterday has fallen thirty years behind and that we have grown up. I find it interesting and appropriate that Dobzhansky's lifetime spans the period of maturation of the fields to which this volume is devoted. This is true in a chronological sense for his birth occurred in the same year, 1900, in which modern genetics began. The rediscovery of Mendel's princi ples and the interpretation of the nature of heredity and variation to which this event led were necessary prerequisites to the development of evolution ary biology as presented in this collection of essays.

Pteridology in the New Millennium by S. Chandra,M. Srivastava Pdf

The National Botanical Research Institute came into being as the 13th among a chain of National Laboratories established during April, 1953 under the Council of Scientific and Industrial Research by the Govt. of India for advanced research in fields of specialisation which have a direct bearing on socio-economic, industrial and scientific advancement of the nation. Christened initially as National Botanic Gardens, the nucleus around which the institution took shape under its founder- Director Late Prof. K. N. Kaul, was a large herbarium of Indian flora and a centu- old botanical garden spread over 35 ha of land on the banks of River Gomti in the heart of Lucknow city. It’s a matter of great pleasure and profound satisfaction to me that a Golden Jubilee volume entitled, “Pteridology in the New Millennium” is being published and released during the Golden Jubilee year of NBRI in the honour of Professor B. K. Nayar who laid the foundation of the Pteridology Laboratory of the NBRI, which is now a well equipped laboratory for the study of Indian pteridophytes. Professor Nayar is a holistic Botanist as evident through his contributions and publications in almost all the areas of study of Pteridophyta. The contribution of Professor Nayar towards the development of modern Pteridology and the role of NBRI in it is indeed great and very important. His publications will be valuable for the younger generation of scientists in the field as well as for the more mature research workers and teachers.

Genomes and Evolution of Charophytes, Bryophytes, Lycophytes and Ferns by Anonim Pdf

Advances in Botanical Research publishes in-depth and up-to-date reviews on a wide range of topics in plant sciences. The series features several reviews by recognized experts on all aspects of plant genetics, biochemistry, cell biology, molecular biology, physiology, and ecology. Volume 78 focuses on the Genomes and Evolution of Charophytes, Bryophytes, Lycophytes, and Ferns. Sequencing of genomes of ‘lower’ animals such as sponges or hydrozoans has much informed our understanding of how metazoans evolved. On the plant side of things, sequencing and comparison of a moss and lycophyte genome with those of green algae and flowering plants has greatly informed our understanding of plant evolution. However, it has also become clear that we need to look into genomes of the closest algal relatives to land plants, the charophytes, and into further genomes of bryophytes, lycophytes, and ferns to unravel how land plants evolved. Features reviews by recognized experts on all aspects of plant genetics, biochemistry, cell biology, molecular biology, physiology, and ecology Focuses on the genomes and evolution of charophytes, bryophytes, lycophytes, and ferns Offers a first time compilation on non-flowering plant genomes Helps unravel how land plants evolved

Spores of the Pteridophyta by Alice F. Tryon,Bernard Lugardon Pdf

This book constitutes a unique, encyclopedic reference work that systematizes and categorizes for the first time in such comprehensive fashion all known fern spores. The dominant feature of the work are the over 350 plates of electron micrographs showing the morphological characteristics of typical representatives of each spore type. The purpose of the book is to provide a complete survey of the available data on the fine structure and composition, development, and evolu- tionary significance of different types of spore walls, which have proven resistant to fossilization throughout geological ages. The classification system developed by the authors as the result of many years of research will be a point of reference, if not "the" systematic basis, for all future publication on the subject. The book will be of great interest to all botanists and evolutionary biologists working with spores and/or ferns, but it will also be of major importance to paleobotanists, palynologists, stratigraphers, and exploration geologists, since the focus of this treatise is on spores as highly adapted and longlived reproductive forms.
