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.

Interest in the biology of African 'wetlands' was initiated in the last century with the hypothesis that Lake Tanganyika was once part of a Jurassic sea, and was furthered by Cunnington's expedition at the beginning of this century which proved that it was not. In the late 1920's, ecological studies, encouraged by the growing importance of inland fisheries, were started hy British, French and Belgian biologists. Some twenty years later several government limnological research centres and fishery departments were established in tropical Africa, and scientific progress was accelerated. Scientific collaboration between the regions south of the Sahara was started formally in 1951 by the Scientific Council for Africa and stimulated by the International Biological Programme (1964-74) with its emphasis on biological productivity. Some of its interests were takcn on by SCOPE which recently selected continental wetlands as a Special Project; hence this book. The five authors, with-Patrick Denny as editor, have made a very valuable contribution both to science and to thc management of Africa's natural rcsourccs: thcy have filled a gap in the synthesis of knowledge about Africa's environments which is long overdue. The term 'wetland' is used today in several different contexts. For this purpose, it excludes the seas and large open inland waters. which are too deep for rooted plants, but includes the huge areas of floodplains and dambos which may change seasonally from standing water to very dry lands.

This guide is motivational and inspiring to the students, weed control managers, communities and others. With great effort, the author describes the weed and weed characters in simpler terms to reach the common people. Eight aquatic invasive weeds have been prohibited in Botswana and their movement within the country is restricted as per the Aquatic Weed (Control) Act of 1986, Botswana. The readers draw attention to how these weeds can be identified in the field and how they can be managed with integrated control measures. With the information presented, we all need to cultivate feelings of protecting our waters and wetlands so that the integrity of the ecosystems is restored. Fears are spread too generously about the threat of aquatic weeds, but there are well-practiced norms, laws and methods available to manage them. The strategies and goals of the Aquatic Weed Control practiced in wetlands of Botswana to manage the weeds and the results obtained from the program can provide confidence in weed control programs for several countries. It is set out how natural selection underlies the great similarities between species and how, when species are isolated as invasive, they become different. With this principle, the author presents, through natural measures, how evolutionary changes can occur in a system where the weeds are controlled.

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
