One of the main reasons cited for inadequate representation of biodiversity in the development processes is a lack of readily available information on inland water taxa. In response to this need for basic for information on species, the IUCN Species Programme conducted a regional assessment of the status and distribution of 2,261 taxa of freshwater fishes, molluscs, odonates, crabs and selected families of aquatic plants from throughout central Africa. This study is based on the collation and analysis of existing information, and the knowledge of regional experts.
The Eastern Mediterranean region supports just over 4.4% of the global human population yet contains only 1.1% of its renewable water resources, which are under constant threat from the impacts of unsustainable water withdrawal, dam development and climate change. This IUCN report and accompanying dataset represents a major advance in the provision of information to help incorporate biodiversity needs into water development planning processes within an Integrated River Basin Management framework. This volume includes species information compiled for each river and lake sub-basin and incorporates information from the assessment conducted by IUCN's Global Species Programme, in collaboration with its partners, of the status and distribution of all described species of freshwater fishes, molluscs, odonates, and plants from across the Eastern Mediterranean with existing information for species of freshwater dependent amphibians, birds, crustaceans, and mammals. This work represents the most comprehensive assessment yet of freshwater biodiversity at the species level for this part of the world.
This assessment is the first overview of the conservation status of 877 northern African freshwater species belonging to five taxonomic groupsfish, molluscs, dragonflies and damselflies, freshwater crabs and aquatic plantsin accordance with the IUCN regional Red List guidelines. Species at risk of regional extinction are mapped and conservation measures are proposed to reduce the probability of future declines.
Decapods are the largest, most prominent, and, unfortunately, most threatened freshwater crustaceans. Advances in Freshwater Decapod Systematics and Biology presents a selection of papers by geographical and domain experts, in taxonomy, phylogenetics, biogeography, life history, and conservation. The major groups of freshwater decapods—crabs, crayfish, prawns, and anomurans—are all represented. This volume includes a chapter commemorating Richard Bott’s influence on freshwater crab/decapod biology; descriptions of seven new species (Atyidae, Aeglidae, Pseudothelphusidae, Potamidae, and Sesarmidae); chapters on larval-based phylogenetics and molecular clock calibration; and reviews of longevity and mortality, and of the global conservation status of freshwater decapods. This volume both reflects the current state of research and serves as a primer for future work and more integrative decapod research. Contributors include: Shane T.

Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.
This situation analysis was undertaken to inform responses to several resolutions made at the 5th World Conservation Congress in 2012 about the plight of large vertebrates in West and Central Africa. It draws on a wide range of information to provide information on the status of these species, important sites, pressures, legislation, the effectiveness of protected areas, and both community-based incentives for conservation and institutional responses. The overriding conclusion is of substantial wildlife declines and inadequate responses to either long-standing pressures or rapidly escalating threats that have emerged in recent years.
