Book Description
The Afrotropical Streams and Rivers: Structure, Ecological Processes and Management is a comprehensive guide that provides assessment of major rivers and tributaries in Africa. Unlike other books available, the editors present a thorough study of geomorphological, hydrological, biological, and ecological processes incorporating a range of plant and animal communities, while considering implications of human communities that depend upon them. This book, edited by a diverse cohort of researchers and/or scholars, is intended as an educational and practical guide for graduate students, researchers and scientists who focus on the biodiversity, conservation and management/policy issues of the African river systems. - Provides a comprehensive introduction to African freshwater rivers, their biota, and abiotic processes. - Contains unique case studies on African streams and rivers. - Organised around an interdisciplinary approach that covers the complex aspects of conservation and management of African river systems on the continent.

Book Description
At the present time, malaria is responsible for a million deaths a year, with 500 million reported cases of the disease and 2.5 billion people at risk of contracting it. The distribution and severity of the disease vary with the causative agents, vectors and environment. Of the 4 possible parasites, only P. falciparum causes fatal forms; the three others have debilitating effects related to frequent disease recurrence and reviviscence. More than 50 species of anophele are involved in the obligatory transmission of the parasite from man to man. Climate, environment and biogeography condition the distribution of anophele species and modulate the intensity of transmission. This is what is known as the biodiversity of malaria. At the present time, more than 90% of P. falciparum malaria deaths occur in tropical Africa where only 10% of the world's population lives. A child dies of malaria every 30 seconds. This continent is home to the most effective vectors and the climate favours transmission. Severe cases also arise in the forested areas of South East Asia, New Guinea and the Amazon region. Throughout the rest of the tropical and subtropical world, the disease caused by P. vivax and/or P. malariae is less serious.

Book Description
This book is the first of four volumes in the Handbook of Zoology series which treat the systematics and biology of Coleoptera. With approximately 350,000 described species, Coleoptera are by far the most species-rich order of insects and the largest group of animals of comparable geological age. The beetle volumes will meet the demand of modern biologists seeking to answer questions about Coleoptera phylogeny, evolution, and ecology. This first Coleoptera volume covers the suborders Archostemata, Myxophaga and Adephaga, and the basal series of Polyphaga, with information on world distribution, biology, morphology of all life stages (including anatomy), phylogeny and comments on taxonomy.

Book Description
Provides a concise, current and accessible overview of running water systems. The book's unifying focus is on rivers and streams as ecosystems in which the particular identity of organisms is not the main emphasis but rather the processes in which they are involved - specifically energy flow and the cycling of materials.

Book Description
Emerging Freshwater Pollutants: Analysis, Fate and Regulations comprises of 20 chapters, all written by leading experts. This book is written in the most practical terms and is easy to understand, with numerous helpful examples and case studies and can be used as a practical guide and important educational tool on issues concerning freshwater emerging pollutants. The organisation of the book exposes the reader in logical succession to the full range of complex scientific and management aspects of emerging freshwater pollutants in the developing world. The book recognises that water chemistry, emerging freshwater pollutants and management are inter-dependent disciplines. The book covers (i) the different monitoring techniques, current analytical approaches and instrumental analyses, (ii) fate and occurrence of emerging pollutants in aquatic systems and (iii) management policies and legislations on emerging pollutants. Thus, subsequent chapters elucidate chemicals with pollution potential, multi-detection approaches to analysis of organic pollutants in water, microplastics effects and photochemical transformation of emerging pollutants in freshwater systems. Whereas, other chapters address oxidation of organic compounds in aquatic systems, biomonitoring systems for detection of toxic levels of water pollutants, and health aspects of water recycling practices. This book melds several different perspectives on the subject of freshwater emerging pollutants and shows the interrelationships between the various professions that deal with water quality issues. Further, within the presentation of each separate chapter is discussion of how the various scientific and management aspects of the subject interrelate. - Includes case studies and practical examples in each chapter - Presents a much-needed interdisciplinary approach, representing the overlap between water chemistry and emerging freshwater pollutants - Provides a thorough introduction to emerging tropical and freshwater pollutants that typically occur in these systems

Book Description
Tropical Stream Ecology describes the main features of tropical streams and their ecology. It covers the major physico-chemical features, important processes such as primary production and organic-matter transformation, as well as the main groups of consumers: invertebrates, fishes and other vertebrates. Information on concepts and paradigms developed in north-temperate latitudes and how they do not match the reality of ecosystems further south is expertly addressed. The pressing matter of conservation of tropical streams and their biodiversity is included in almost every chapter, with a final chapter providing a synthesis on conservation issues. For the first time, Tropical Stream Ecology places an important emphasis on viewing research carried out in contributions from international literature. - First synthetic account of the ecology of all types of tropical streams - Covers all of the major tropical regions - Detailed consideration of possible fundamental differences between tropical and temperate stream ecosystems - Threats faced by tropical stream ecosystems and possible conservation actions - Descriptions and synstheses life-histories and breeding patterns of major aquatic consumers (fishes, invertebrates)

Book Description
Concerns about global biodiversity are rising dramatically, yet we are lagging behind in the most basic prerequisite for its understanding and conservation: the inventory. Insect species may make up five or ten times the number of all other plant and animal species combined, and as such they represent one of the major challenges in biosystematic science. World Catalogue of Insects is an initiative aiming at compiling worldscale, authoritative catalogues of monophyletic insect taxa. We are therefore proud to launch this major series. Volumes will as a minimum contain standard nomenclatoral information on all names pertaining to the taxon treated, including type locality and distribution to the extent this is relevant. Additional information is optional, e. g., location, status and condition of types; biology; bibliographical information; pest status; vector status; etc. This volume two focuses on Hydrophiloidea (Coleoptera).
