A reduction in forest area should result in a reduction of its number of species and, moreover, do so in a characteristic way according to the familiar species-area relationship. Brooks, Pimm & Collar (1997) applied this formula to the losses in forest area in the Philippines and Indonesia. Independently derived totals of the number of endemic bird species that are threatened with extinction broadly agree with these predicted losses. In some cases, however, predicted losses overestimate or underestimate the actual numbers of threatened species.
Resource Type: Journal PapersThis atlas provides a comprehensive overview of what is currently known about all six species of great apes - chimpanzee, bonobo, Sumatran orangutan, Bornean orangutan, eastern gorilla, and western gorilla. It gives a thorough background on ape behaviour and ecology for each species, including detailed habitat requirements, the apes' ecological role, and the possible consequences of their decline.
Despite the dedicated efforts of many individuals and organizations, the great apes all fall into the Endangered or Critically Endangered category of the IUCN Red List. This atlas offers a full description of the threats, current conservation efforts, and additional protection needed for each species across its entire range.
•Covers all six species of great apes
•Provides the most up-to-date and comprehensive data available
•More than 150 full-colour photos
•More than 40 full-colour maps and diagrams

The range of information on biodiversity currently available via the Internet is reviewed and its accessibility, usefulness and relevance to biodiversity research and to policy decision making assessed. Commercial and non-commercial databases are reviewed. The future of information via the net is also reviewed, in particular the role of the `Clearing House Mechanism' of the Convention on Biological Diversity and the Biodiversity Conservation Information System.

Resource Type: ReportsThe World's oceans play a crucial role for life on the planet. Healthy seas and the services they provide are key to the future development of mankind. Our seas are highly dynamic, structured and complex systems. The seafloor consists of vast shelves and plains with huge mountains, canyons and trenches which dwarf similar structures on land. Ocean currents transport water masses many times larger than all rivers on Earth combined.
In this report, the locations of the most productive fishing grounds in the World - from shallow, coastal waters to the deep and high seas - are compared to projected scenarios of climate change, ocean acidification, coral bleaching, intensity of fisheries, land-based pollution, increase of invasive species infestations and growth in coastal development.
Resource Type: ReportsA table is provided of 122 bird species with restricted breeding distributions and for which Nepal may hold significant populations. Habitat threats and population changes are detailed for 33 species for which Nepal may be especially important. The vital importance of Nepal's forests to Nepal's avifauna is emphasised.
Resource Type: Journal PapersSmall local hunting communities in Siberia are very distant from any governmental control. Hunted waterbird species, including globally and regionally threatened species, rely for their well-being on the self regulation of remote hunting communities. Interviewed hunters showed a profound knowledge of Baikal Teal, its population status, and the causes of their past decline. Whether the knowledge is shared by other communities in the region and beyond in Northern Siberia needs verification.

The Great Apes, including the chimpanzee, gorilla and orangutan, are threatened with extinction. All species are rapidly declining in abundance, even within protected areas.The main factors responsible for this decline are loss and degradation of habitat, and hunting. Construction of roads in forest areas is particularly damaging, as such development facilitates hunting and other activities which lead to habitat destruction.
This report assesses the impact of infrastructural development on great ape populations, using the GLOBIO modelling approach. GLOBIO is a multivariable spatial model, which estimates the extent of land area with reduced abundance and diversity of living organisms, as a result of infrastructural development. The model can also be used to develop scenarios of possible future impacts, based on the current rates of infrastructural development.
