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.

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 open access volume presents a comprehensive account of all aspects of biological invasions in South Africa, where research has been conducted over more than three decades, and where bold initiatives have been implemented in attempts to control invasions and to reduce their ecological, economic and social effects. It covers a broad range of themes, including history, policy development and implementation, the status of invasions of animals and plants in terrestrial, marine and freshwater environments, the development of a robust ecological theory around biological invasions, the effectiveness of management interventions, and scenarios for the future. The South African situation stands out because of the remarkable diversity of the country, and the wide range of problems encountered in its varied ecosystems, which has resulted in a disproportionate investment into both research and management. The South African experience holds many lessons for other parts of the world, and this book should be of immense value to researchers, students, managers, and policy-makers who deal with biological invasions and ecosystem management and conservation in most other regions.

Freshwater life – the first illustrated field guide of its kind for the wider southern African region – describes a vast range of plant and animal groups in a single volume. A ground-breaking concept that encompasses diverse groups from the large and conspicuous vertebrates to the diverse microscopic taxa, the book facilitates identification and describes the ecology of more than 1,000 freshwater organisms. Species have been selected on the basis of how likely they are to be encountered, and each account is accompanied by photographs and a distribution map. A comprehensive introduction details the ecology and signifi cance of freshwater systems. This indispensible, easy-to-use guide will prove invaluable to outdoor enthusiasts, students and conservationists.
