Biodiversity information on the Internet: cornucopia or confusion? »
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.

Some important birds and forests in Nepal »
A 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.

Status of the Baikal Teal in the Lower Indigirka Basin, Siberia »
Small 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.

Assessing the status of poorly known species: Lessons from partridges and pheasants of Southeast Asia »
There is an urgent need to evaluate the status of groups of species for conservation purposes. A species' status is indicated by both its distribution and abundance, and the rate at which these components are changing. This information is scarce for many tropical forest species. We produced four measures of status based on locality and habitat data for 25 partridges and pheasants of Southeast Asia.

Declining Ruff Philomachus pugnax populations: a response to global warming? »
Ruff breeding populations have declined widely and in all habitats across temperate Eurasia. Of an estimated population of 2.2-2.8 million birds, 98% are now confined to habitats in the Arctic tundra.
The emerging picture is that the population has shifted northwards and eastwards and has retreated from the wet grassland habitats formerly occupied along the southern edges of its range. It is suggested that the causes are probably of a global nature and may be linked with climate change. It is unclear whether the total population has declined or only shifted north and east. More co-ordinated and systematic monitoring of breeding and wintering populations will be necessary before a full understanding of these changes can be reached.

Threat from deforestation to montane and lowland birds and mammals in insular South-east Asia »
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.

First indications of a sharp population decline in the globally threatened Spoon-billed Sandpiper Eurynorhuchus pygmeus »
Spoon-billed Sandpiper Eurynorhynchus pygmeus is classed as globally Vulnerable, based on the only available population estimate, made in 1977, of 2,000-2,800 pairs. Surveys for breeding Spoon-billed Sandpipers were carried out in summer 2000 on the Anadyr estuary coast, the Chukotka autonomous region, Russia. Although six new breeding sites were found, only 16-17 breeding males/pairs were recorded on the northern coast of the Anadyr estuary and five males/pairs on the southern coast and more southerly lagoons. These numbers were much lower than expected, and the species was not recorded in several apparently suitable areas.

Book review: Data Mining for Global Trends in Mountain Biodiversity »
With a view to the future, the book points the reader to the Mountain Biodiversity Portal (http://www.mountainbiodiversity.org) that has just been launched by the GMBA and the Global Biodiversity Information Facility (GBIF). This tool has the potential to greatly facilitate access to mountain biodiversity data because it allows users to find GBIF data for specific elevational and thermal belts within their region of interest. A very similar tool already allows users of the World Database on Protected Areas (http://www.wdpa.org) to find GBIF data for a protected area of interest. Thanks to these collaborative efforts, researchers will increasingly get the data they require without the need to carry out time-consuming overlays of species and other data sets for their region of interest. The GMBA/GBIF Mountain Biodiversity Portal is a fine example for the technical possibilities of our time and will certainly help to further stimulate the creative use of georeferenced biodiversity data promoted by this book.

La délimitation des montagnes européennes (Delineating Europe's mountains) »
As the importance of mountain spaces is more widely recogised, it seems necessary to establish a coherent definition of these spaces. The UNEP World Conservation Monitoring Centre (UNEP-WCMC) proposed the first global delineation in 2000. However, certain European countries have used national definitions of mountain spaces since the 1950s. Within the framework of social and economic integration policies at the heart of the European Union, an agreed delineation of European mountain spaces has been established, based on the definition proposed by UNEP-WCMC. The process of adaptation of the global definition to the European context is described, as well as the results for 29 European countries.
