Book Description
This book is an attempt to compile and integrate the information documented by many botanists, both Egyptians and others, about the vegetation of Egypt. The ? rst treatise on the ? ora of Egypt, by Petrus Forsskal, was published in 1775. Records of the Egyptian ? ora made during the Napoleonic expedition to Egypt (1778–1801) were provided by A. R. Delile from 1809 to 1812 (Kassas, 1981). The early beginning of ecological studies of the vegetation of Egypt extended to the mid-nineteenth century. Two traditions may be recognized. The ? rst was general exploration and survey, for which one name is symbolic: Georges-Auguste Schweinfurth (1836–1925), a German scientist and explorer who lived in Egypt from 1863 to 1914. The second tradition was ecophysiological to explain the plant life in the dry desert. The work of G. Volkens (1887) remains a classic on xeroph- ism. These two traditions were maintained and expanded in further phases of e- logical development associated with the establishment of the Egyptian University in 1925 (now the University of Cairo). The ? rst professor of botany was the Swedish Gunnar Tackholm (1925–1929). He died young, and his wife Vivi Tackholm devoted her life to studying the ? ora of Egypt and gave leadership and inspiration to plant taxonomists and plant ecologists in Egypt for some 50 years. She died in 1978. The second professor of botany in Egypt was F. W.

Plant Responses to Hyperarid Desert Environments
Author: Monier M. Abd El-Ghani
Publisher: Springer
ISBN: 3319591355
Category : Science
Languages : en
Pages : 601
Book Description
This book provides a comprehensive discussion on plant responses in hyperarid regions of Egypt, China, Mexico, and Pakistan. It describes their location, physiographic features, accidental vegetation along two transects, endangered vegetation species, human impact, and variety of plant types (e.g. climbing, succulent, and parasitic). Studies on biotic and abiotic interactions, plant biodiversity, and soil-plant relationships are also covered. Covering a wide range of plant conditions and adaptations, this book analyzes what happens when plants must endure very high temperatures and aridity. Plants have adapted by evolving their physical structure to store and conserve water. Examples are the absence of leaves which reduces transpiration and the growth of extremely long roots, allowing them to acquire moisture at, or near the water table. Plants in hyperarid habitats have also made behavioral adaptations in order to survive by synchronizing with the seasons of greatest moisture and/or coolest temperatures. For example, desert perennials remain dormant during dry periods of the year, then spring to life when water becomes available. The book includes many color illustrations, and has extensive and up-to-date references for further reading.

Climate - Vegetation:
Author: M.A. Zahran
Publisher: Springer Science & Business Media
ISBN: 9048185955
Category : Nature
Languages : en
Pages : 344
Book Description
Deserts are unique ecosystems with their own biotic and abiotic components, and are often rich in renewable natural resources, the appropriate management of which can contribute significantly to the sustainable management of desert regions for the welfare of the people. Yet while there are many books on the flora of the countries fringing the important desert countries of the Mediterranean and Red Seas, there or few books reporting on their ecophysiology and vegetation ecology. This book presents the vegetation types of the African and Asian countries of the Mediterranean and Red Sea coastal regions, and discusses the ecological threats and economic applications of these critical resources. In particular, it examines the relationships between climate and vegetation, and discusses these within the context of desertification, agro-industrial applications, ecotourism and sustainable development. The book will provide a valuable reference for researchers and graduate students involved in plant ecology, biogeography, economic botany and environmental management in the Afro-Asian Mediterranean and Red Sea coastal regions, as well as other desert regions around the world.

Antelopes
Author: David P. Mallon
Publisher: IUCN
ISBN: 9782831705941
Category : Nature
Languages : en
Pages : 276
Book Description
Antelope herds numbering in the tens of thousands formerly occurred across the steppes and semideserts of Eurasia and India, but these have nearly all been reduced to fractions of their earlier size; antelope populations are now fragmented across the region, and during recent decades several species have disappeared altogether. Threats include hunting, loss of habitat, population fragmentation, inadequate protected area coverage, poorly-developed administrative structures, under-resourcing of conservation programmes, and lack of enforcement of existing legislation. Rising human population growth and economic development constantly increases pressure on land and natural resources. There is a consequent need for integrated rural development, and community-based conservation projects, which have the full participation of local people at the planning and execution stages.This publication, Part 4 of the Global Antelope Survey, covers 37 countries in the region, and actions to conserve antelope populations are listed in each country report.

Man Eating Plants
Author: Jonathan Spitz
Publisher: 6th Sense Press
ISBN: 1662932898
Category : Health & Fitness
Languages : en
Pages : 463
Book Description
Over the past two million years, humans evolved from an obscure herbivorous species living in the tropical forests of equatorial Africa to become the world’s most populous carnivorous apex predator species. In the 21st century, this fateful change in the human diet from plant to animal sourced foods is the leading cause of chronic degenerative disease, runaway climate change, and mass species extinction. Man Eating Plants: How a Vegan Diet Can Save the World weaves together published works by the world’s leading scientists and historians to narrate how we arrived at these three interrelated crises and how we can save the world by transitioning back to our natural plant-based diet.

Book Description
This volume was first published in 1981. The history of man's use of arid lands is a sad record of deterioration of the natural resource base and of low and declining living standards for the 300 million people who live in them. One prerequisite to meeting the challenge of reversing the deterioration and of raising living standards is a sound knowledge of the natural ecosystems.

Management and Development of Agricultural and Natural Resources in Egypt's Desert
Author: Ahmed A. Elkhouly
Publisher: Springer Nature
ISBN: 3030731618
Category : Science
Languages : en
Pages : 544
Book Description
This book reviews the economic potential of various natural resources found in the Egyptian deserts that could help fill the food gap in Egypt, e.g., the date palm, olives, and domestic animals. Bearing in mind that the entire country is subject to arid or hyperarid climatic conditions, only a small portion (3% of total area) is agriculturally productive in comparison, the dominant deserts. These aspects, combined with a growing population (ca. 100 million citizens) and water resources scarcity, have produced severe adverse effects on natural resource utilization. This book presents innovative methods for addressing desert soil's key problems (soil erosion, salinity, pollution, decreased fertility, minerals, and weed and pest control). Its goal is to help authorities reclaim the desert and optimally utilize the minerals and the available natural resources to support the sustainability agenda 2030. Besides, it offers researchers guidance on remaining gaps and future research directions. Lastly and importantly, it provides essential information on investment opportunities in desert cultivation, such as the fields of food, fodder, and medicinal plants.
