A team of researchers, students, and local staff surveyed the vertebrate and invertebrate species in four areas of the Okavango Delta in northwestern Botswana. The survey reports water quality as benign and healthy with the exception of low dissolved oxygen levels. About a fourth of the 1250 plant species known from the Delta were recorded and were found to have moderate diversity and surprisingly uniform populations. The findings of diversity in the fish communities and a breeding colony harboring fourteen endangered bird species provide substantial support for the report's recommendations on conserving this ecologically significant area.
Liberia s national forests are among the last refuges in West Africa for large migrating mammals. This volume summarizes the findings of a biodiversity survey of three forests as part of the Liberia Forestry Initiative, an effort to rehabilitate and reform Liberia s threatened woodlands. The survey found each forest to harbor a wealth of biodiversity and a significant number of species of conservation concern. Researchers here document the discovery of six species new to science, report eighteen newfindings for Liberia, and present conservation recommendations based on survey results."
This volume, #31 in the series, reports the results of a marine survey in 2002 off the northwestern coast of Madagascar. This marine area is one that many conservationists think has the greatest potential in all of Madagascar for the development of both ecotourism and marine protected areas. The survey documented a rich variety of coral, mollusk, and fish species, and the report makes further recommendations for conservation in the region."
Inland waters, lakes, rivers, and their connected wetlands are the most important and the most vulnerable sources of freshwater on the planet. The ecology of these systems includes biology as well as human populations and civilization. Inland waters and wetlands are highly susceptible to chemical and biological pollutants from natural or human sources, changes in watershed dynamics due to the establishment of dams and reservoirs, and land use changes from agriculture and industry. This book provides a comprehensive review of issues involving inland waters and discusses many worldwide inland water systems. The main topics of this text are water quality investigation, analyses of the ecology of inland water systems, remote sensing observation and numerical modeling methods, and biodiversity investigations.
Aquatic plants play a critically important role in maintaining ecosystem health. They are natural biological filters in freshwater and estuarine wetlands; they contribute to the reproductive success of many organisms, some of which are harvested for food; they assist in flood control; and they are prominent elements in the aesthetics and recreational use of freshwater and estuarine habitats. Despite this globally recognized importance, wetlands have faced and continue to face threats from the encroachment of human activities. The Biology of Aquatic and Wetland Plants is a thorough and up-to-date textbook devoted to these plants and their interactions with the environment. The focus is on botanical diversity from the perspective of evolutionary relationships, emphasizing the role of evolution in shaping adaptations to the aquatic environment. By incorporating recent findings on the phylogeny of green plants, with special emphasis on the angiosperms, the text is broadly useful for courses in plant biology, physiology, and ecology. Additionally, a chapter on population biology and evolutionary ecology complements the evolutionary backdrop of hydrophyte biology by examining the details of speciation and applications of modern genetic approaches to aquatic plant conservation. Key Features • Synthesizes recent and seminal literature on aquatic and wetland plants • Emphasizes evolutionary history as a factor influencing adaptations to the wetland environment • Provides a global perspective on plant diversity and threats facing wetland ecosystems • Highlights research needs in the field of aquatic and wetland plant biology • Includes 280 figures, with more than 300 color photographs, and 41 tables to provide ease of access to important concepts and information
Floods and droughts brought about by the vagaries of nature cause extensive damage to the livelihoods of people as well as the environment. Knowledge of the need to adopt sustainable practices toward water use, reuse, and management is critical and the scope of this book deals precisely with sustainable practices in water management. The purpose of this book is to provide the reader with abundant and relevant information on all aspects related to water sustainability: water reuse, dynamics of transboundary waterways, economic tools to analyze sustainability, water-energy-food nexus, computer simulation models to study watershed models, and so forth. Although this book may not provide readers with comprehensive information on all aspects related to water sustainability, it will provide constructive data and content on the current trends and advancements in sustainable practices related to water. The book is intended to further motivate readers and scientists alike to look further and make concerted efforts toward promoting better and effective water management.

An anthology of aquatic plants is an excellent collection of knowledge about anything in fresh, marine, or polluted waters. This pictorial guide deals with aquatic and wetland plants from the Okavango to the transboundary rivers to the rainwater ponds and dams. Organized and written in a way that will make information easily accessible to specialists and non-specialists alike. The guide/book highlights the diversity and vital ecological importance of the group of plants, providing descriptions and identification keys for emergent, floating-leaved, and submerged aquatic plants found in Botswana. They serve as a source of food and shelter for the aquatic fauna, thus forming the basis of aquatic wildlife conservation practices. They are economically useful in providing medicinal and aesthetic value. Aquatic plants prevent and maintain erosion, water turbidity, and the source of oxygen in the water. Information on invasive plants, such as Kariba/salvinia weed, water lettuce, and water hyacinth that threaten Botswana's aquatic ecosystems, is briefly described. In total, 194 plant species are presented in the guide. All technical terms are explained in a comprehensive glossary. This is the first such flora to cover aquatic and wetland plants for the entire geographical area, excluding grasses and sedges. It will suit a large age range, from little ones who want to look at the pictures to primary school children. If you have an explorer's spirit and a thirst for finding something new, then aquatic life will never disappoint. The physical book itself is stunning, with a handsome cover with common water lily that makes it pretty enough to sit on the coffee table but entertaining enough to keep kids glued to the pages. When the two characters from a different native, who rose in the same city of Aizawl, meet and fall in love during PUC, his jealous gay friend circles a rumor and tries to interfere in their affairs. Her love sadly feels unrequited due to his shy and reclusive nature followed by some tragic incidents that make all her attempts go in vain. She also doesn’t understand his gesture of acceptance and things remain in a state of oblivion for a long time. Her sedulousness doesn’t allow giving up on him even after they part ways to pursue their higher studies. But her naiveness again fails her in catching his clues before he turns into a severe hophead after his mother’s demise. A lot changes in their lives by the time he comes close to expressing his hidden love for her and is about to propose for marriage. Despite both being settled in the South, every time some divine energy would stop them from meeting in one place. Unease in his mind, he starts revealing his feelings and relevant secrets after his marriage and comes to a point when she learns how life had been unkind to both of them and they begin expressing their regrets. It is a tragic love story that starts with love and ends with friendship. After reading the book, you might wonder whether they will remain just as incomplete stories that are waiting to be completed like how they called themselves.
This edited book highlights the potential and actual contributions of the sustainable management and utilization of indigenous biological resources and environment for the development of Africa. The book centers on documenting current trends and issues in the field of resource use and conservation with the view of emphasizing their benefits to the pursuit of development within the region. By documenting the array of natural resources and environment in Africa, this book addresses the topical knowledge and understanding gaps that characterize conservation (rationale for sustainable resource exploration), utilization patterns, and conservation challenges including policy status, environmental threats, impacts of tourism, reduction in food resources, etc., and their effects on the sustainable development of Africa. Through an integrated approach, the book focuses on below and above-ground biological resources and the diverse scales of environment that characterize Africa. This collection of works is very helpful for natural and social scientists, policymakers, strategists, researchers, government and non-government organizations, biodiversity and environmental managers, climate change scientists, practitioners, activists, conservationists, academics, ecologists, undergraduate and postgraduate students, and others who want to learn about and understand the best way to use and protect Africa's resources and heritage sustainably.
