Endangered species

Chelonian Research Monographs is an international peer-reviewed scientific publication series for monograph-length manuscripts, collected proceedings of symposia, edited compilations, and other longer turtle-related research documents.

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 report reviews the conservation status of all native marine fishes occurring in the Mediterranean Sea, based on the assessments for 513 species and 6 subspecies using the IUCN’s Red List methodology. It identifies those marine fish species that are threatened with extinction at the regional level so that appropriate conservation actions can be taken to improve their conservation status.

As part of a comprehensive strategy to highlight and help prioritize urgently needed conservation action for the most critically endangered turtles and tortoises in the world, the Turtle Conservation Coalition have highlighted the Top 25 most endangered species every four years since 2003. In this third installment, more than 25 species are covered and the information presented was provided by the coalition rather than solely by one or two organizations.

Biodiversity within inland water ecosystems in the Eastern Himalaya region is both highly diverse and of great regional importance to livelihoods and economies. However, development activities are not always compatible with the conservation of this diversity, and the ecosystem requirements of biodiversity are frequently not considered in the development planning process.

The threatened species categories used in Red Data Books and Red Lists have been in place for almost 30 years. The IUCN Red List Categories and Criteria provide an easily and widely understood system for classifying species at high risk of global extinction, so as to focus attention on conservation measures designed to protect them.
