Over the years they have taken on an almost mythical quality, with many doubting whether they existed at all. In 1994 the local forestry department maintained that there was only one surviving Knysna elephant, the seldom seen female known as The Matriarch. The Knysna elephant was thus described as 'functionally extinct'. This was the official stance until September 2000 when forest guard Wilfred Oraai encountered and photographed a young bull from a distance of some thirty metres. The question arose: who was its mother? And, indeed, who was its father? In 2001 Gareth Patterson began an independent study of the Knysna elephant. For the next seven years he covered thousands of kilometres on foot, following ancient elephant paths through the dense Afromontane forest and the surrounding mountain fynbos. He found abundant signs to suggest that, far from dying out, the Knysna elephants are, quietly and secretly, holding their own. Patterson's fieldwork, and his dna research in collaboration with conservation geneticist Lori Eggert, established that at least five young females exist, lending support to Patterson's growing evidence that the Knysna forest and its surroundings are home to a small herd of young elephants. The Secret Elephants is the story of these remarkable animals that fought their way back from the brink of extinction without any help from humankind.

DOWNLOAD EBOOK →Seaweed is used in many countries for very different purposes - directly as food, especially in sushi, as a source of phycocolloids, extraction of compounds with antiviral, antibacterial or antitumor activity and as biofertilizers. About four million tons of seaweed are harvested annually worldwide. Of the various species known, less than 20 account for 90% of the biomass exploited commercially. This book details 147 species of edible seaweed, including scientific name and respective common names, geographic location, nutritional composition, uses and is extensively illustrated.

DOWNLOAD EBOOK →Writing the Ancestral River is an illuminating and unusual biography of the Kowie River in the Eastern Cape. This tidal river runs through the centre of what used to be called the Zuurveld, a formative meeting ground of different peoples who have shaped our history: Khoikhoi herders, Xhosa pastoralists, Dutch trekboers and British settlers. Their direct descendants continue to live in the area and interact in ways that have been decisively shaped by their shared history. Besides being a social history, this is also a natural history of the river and its catchment area, where dinosaurs once roamed and cycads still grow. As the book shows, the natural world of the Kowie has felt the effects of human settlement, most strikingly through the establishment of a harbour at the mouth of the river in the 19th century and the development of a marina in the late 20th century. Both projects have had a decisive and deleterious impact on the Kowie. People are increasingly reconnecting with nature and justice through rivers. Acknowledging the past, and the inter-generational, racialised privileges, damages and denials it established and perpetuates, is necessary for any shared future. By focusing on this `little' river, the book raises larger questions about colonialism, capitalism, `development' and ecology, and asks us to consider the connections between social and environmental injustice.

DOWNLOAD EBOOK →Decapods are a culmination of nearly 600 million years of Crustacean evolution, during which time they have radiated into a variety of superfamilies, families, genera and species which occupy a variety of niches from fresh mountain streams to the abysses of the oceans. This book will fill a gap in the current literature on southern African decapods. Since Barnard published his Descriptive Catalogue of South African Decapod Crustacea in 1950, there have been numerous additions and name changes. This publication updates the taxonomy, and includes ecological and fisheries information. In addition, Kensley’s (1981) distributional checklist for the region has been updated and includes large numbers of new species and records for the region, bringing the total number of decapod to over 1000 species. Although not exhaustive, 262 species are featured, some of which are beautiful, some have commercial or artisinal value, both for consumption and the aquarium, and some have important ecological functions, while others are rare or interesting. For each species there is a photograph, synonymies, common names, a description, ecological information and name derivation (etymology). All the decapod families found in South Africa are described, some new, along with chapters on decapod research history in southern Africa, commercial and artisinal food value of decapods, biodiversity and future research direction. The book is arranged systematically, as taxonomy is based on phylogeny, starting with the earliest forms and progressing to the most derived and advanced forms, and will serve to stimulate interest and future research into southern Africa’s rich decapod biodiversity, especially at a time when biodiversity itself is threatened by global warming, coral bleaching and habitat loss. It will appeal to people interested in Decapoda, including academics, scholars, students, fishermen, aquarists, aquaculturists, recreational snorkel and SCUBA divers, as well as those interested in conservation, biodiversity, management and governance.
