ISBN: 1775843173
Category : Nature
Languages : en
Pages : 1823

Book Description
Namaqualand is justifiably famous for the floral wonderland it becomes in spring, when seas of bright flowers carpet the land. Astonishingly, the carpet comprises some 3,800 species, of which 28% are endemic. This book introduces nearly 600 species, highlighting those most commonly found, most conspicuous, spectacular or interesting, as well as endemics. An introduction touches on the species selection for the book, the climatic and topographical subregions within Namaqualand, plant names and uses, and conservation issues. The concise species descriptions also give seed and fruit details, uses, local growing conditions and flowering times, along with beautiful full-colour photographs. This is a must-have guide for visitors to Namaqualand, or for anyone interested in the wild flowers of southern Africa.

Positive Interactions and Interdependence in Plant Communities

Author: Ragan M. Callaway
Publisher: Springer
ISBN: 9781402062230
Category : Science
Languages : en
Pages : 404

Book Description
This book marshals ecological literature from the last century on facilitation to make the case against the widely accepted individualistic notion of community organization. It examines the idea that positive interactions are more prevalent in physically stressful conditions. Coverage also includes species specificity in facilitative interactions, indirect facilitative interactions, and potential evolutionary aspects of positive interactions.

Understanding Flowers and Flowering Second Edition

Author: Beverley Glover
Publisher:
ISBN: 019966160X
Category : Gardening
Languages : en
Pages : 316

Book Description
Flowers are the beautiful and complex reproductive structures of the angiosperms, one of the most diverse and successful groups of living organisms. The underlying thesis of this book is that to fully understand plant development (and why flowers differ in shape, structure and colour), it is necessary to understand why it is advantageous for them to look like they do. Conversely, in order to fully understand plant ecology, it is necessary to appreciate how floral structures have developed and evolved. Uniquely, this book addresses flowers and flowering from both a molecular genetic perspective (considering flower induction, development and self-incompatibility) and an ecological perspective (looking at the selective pressures placed on plants by pollinators, and the consequences for animal-plant co-evolution). Understanding Flowers and Flowering, the first edition of which won BES Marsh Book of the Year in 2009, begins by considering the evolution of flowers and the history of research into their development. This is followed by a detailed description of the processes which lead to flower production in model plants. The book then examines how flowers differ in shape, structure and colour, and how these differences are generated. Finally it assesses the role of these various aspects of floral biology in attracting pollinators and ensuring successful reproduction. This new edition has been completely revised and updated to reflect the latest advances in the field, especially an increased understanding of the evolution of floral traits. New chapters consider the genetic basis of the floral transition in diverse species, as well as the evolutionary lability of floral form. There is a new focus throughout on both phylogenetic position and morphological diversity across the angiosperm phylogeny. Understanding Flowers and Flowering continues to provide the first truly integrated study of the topic - one that discusses both the how and why of flowering plant reproductive biology.

The Last Elephants

Author: Colin Bell
Publisher: Penguin Random House South Africa
ISBN: 1775846830
Category : Nature
Languages : en
Pages : 563

Book Description
The Africa-wide Great Elephant Census of 2016 produced shocking findings: a decimated elephant population whose numbers were continuing to plummet. Elephants are killed, on average, every 15–20 minutes – a situation that will see the final demise of these intelligent, extraordinary animals in less than three decades. They are a species in crisis. This magnificent book offers chapters written by the most prominent people in the realm of conservation and wildlife, among them researchers, conservationists, film makers, criminologists, TV personalities and journalists. Photographs have been selected from among Africa’s best wildlife photographers, and the Foreword is provided by Prince William. It is hoped this book will create awareness of the devastating loss of elephant lives in Africa and stem the tide of poaching and hunting; that it will inspire the delegates to CITES to make informed decisions to ensure that all loopholes in the ivory trade are closed; and that countries receiving and using ivory (both legal and poached) – primarily China, Vietnam, Laos and Japan – ban and strenuously police its trade and use within their borders, actively pursuing and arresting syndicate leaders driving the cruel poaching tsunami. This book is also a tribute to the many people who work for the welfare of elephants, particularly those who risk their lives for wildlife each day, often for little or no pay – in particular the field rangers and the anti-poaching teams; and to the many communities around Africa that have elected to work with elephants and not against them. The Last Elephants – is the title prophetic? We hope not, but the signs are worrying.

Plant Bioproducts

Author: Guanqun Chen
Publisher: Springer
ISBN: 1493986163
Category : Science
Languages : en
Pages : 276

Book Description
Among the major challenges facing society today, seeking renewable alternatives to petroleum-based fuels and manufactured goods is critically important to reducing society’s dependency on petroleum and tackling environmental issues associated with petroleum use. In recent years there has been considerable research targeted toward the development of plant-derived bioproducts to replace petrochemical feedstocks for both fuel and manufacturing. Plants not only provide a large amount of renewable biomass, but their biochemical diversity also offers many chemical and molecular tools for the production of new products through biotechnology. Plant Bioproducts is an introduction to the production and application of plant bioproducts, including biofuels, bioplastics, and biochemicals for the manufacturing sector. Contributing authors examine various bioproducts with respect to their basic chemistry, relationship to current petrochemical-based products, and strategies for their production in plants. Chapters cover the integrated roles of agronomy, plant breeding, biotechnology, and biorefining in the context of bioproduct development. Environmental, economic, ethical, and social issues surrounding bioproducts, including the use of genetically modified crops, challenges to food security, and consumer acceptance, are also covered.

Soils of South Africa

Author: Martin Fey

ISBN: 1139495291
Category : Technology & Engineering
Languages : en
Pages : 289

Book Description
Soils of South Africa is the first book in seventy years that provides a comprehensive account of South African soils. The book arranges more than seventy soil forms into fourteen groups and then provides, for each group: • maps showing their distribution and abundance throughout South Africa • descriptions of morphological, chemical and physical properties • a detailed account of classification and its correlation with international systems • a discussion of soil genesis which includes a review of relevant research papers • appraisal of soil quality from a land use perspective as well as for its ecological significance • illustrative examples of soil profiles with analytical data and accompanying interpretations. There is also a fascinating account of the special relationship that exists between South African animals and soil environments. Soils of South Africa should interest students and researchers in the earth, environmental and biological sciences, as well as environmental practitioners, farmers, foresters and civil engineers.
