Wetland ecosystems and the amazing diversity of plants and animals that inhabit them are thought to be more threatened than any other ecosystem. The Okavango Delta, as the world's largest inland delta, is no exception. This book, published for World Wetlands Day, is both a celebration of the diversity of aquatic life in the Okavango Delta, and is an inspiration to decision makers throughout the region to work together to ensure the survival of one of the world's most beautiful and valuable wetlands. Few natural places in the world offer so much value to people in combination with such aesthetic appeal. Beginning with an explanation of the functioning of the Delta, the book describes (with the aid of many excellent graphics), the catchment areas in Angola and the passage of the Okavango River through Namibia, and goes on to reveal the physical, hydrological and ecological processes governing the working of the Delta itself. Subsequent chapters reveal the value of the Delta in

The book takes us to women-centred events in Gaborone, the capital city of Botswana. Data was collected from the conversations and events women hold with and for one another on the occasions of bridal, Naomi/Laban, and baby showers. Defining Ubuntu/Botho as the belief that our humanity is only measured by our capacity to welcome, respect and empower the other, this research-based book analyses how women practise Ubuntu/Botho in the urban spaces where the community easily disintegrates to individualism, isolation and poverty. It seeks to explore how Ubuntu/Botho intersects with gender and navigates its space around patriarchy, marriage, motherhood, family and community. It explores rituals and connections between women of different generations such as mothers and daughters, daughters-in-law and mothers-in-law, children and mothers, and their struggles to uphold Ubuntu/Botho in their families, communities and workspaces in the face of patriarchy, urbanisation, capitalism and neo-liberalism. The book employs and generates a multitude of methods and theories to highlight women mothering and delivering Ubuntu/Botho in the urban space communities.

Intraspecific communication involves the activation of chemoreceptors and subsequent activation of different central areas that coordinate the responses of the entire organism—ranging from behavioral modification to modulation of hormones release. Animals emit intraspecific chemical signals, often referred to as pheromones, to advertise their presence to members of the same species and to regulate interactions aimed at establishing and regulating social and reproductive bonds. In the last two decades, scientists have developed a greater understanding of the neural processing of these chemical signals. Neurobiology of Chemical Communication explores the role of the chemical senses in mediat...
