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.

Potential impact of climate change and reindeer density on tundra indicator species in the Barents Sea region »
Climate change is expected to alter the distribution of habitats and thus the distribution of species connected with these habitats in the terrestrial Barents Sea region. It was hypothesised that wild species connected with the tundra and open-land biome may be particularly at risk as forest area expands. Fourteen species of birds were identified as useful indicators for the biodiversity dependent upon this biome.

Biodiversity trends in Europe: development and testing of a species trend indicator for evaluating progress towards the 2010 target »
This paper presents a trial of a species population trend indicator for evaluating progress towards the 2010 biodiversity target in Europe, using existing data. The indicator integrates trends on different species (groups), and can be aggregated across habitats and countries. Thus, the indicator can deliver both headline messages for high-level decision-making and detailed information for in-depth analysis, using data from different sources, collected with different methods.

Bamboo diversity: the need for a Red List review »
This review focuses on woody bamboos with the highest diversity recorded in the Asia-Pacific region where bamboos play a major role in ecosystem dynamics in many forests.
The genetic diversity of the remaining forest bamboos, of which many are highly susceptible to deforestation, is of great concern and an accurate information base is required as a foundation for policy and management decisions affecting bamboo. A programme to strengthen the Red List assessments of bamboo species status is also needed, one that prioritizes the assessment of species with the smallest estimated geographical ranges and least remaining habitat.

The Living Planet Index: using species population time series to track trends in biodiversity »
The Living Planet Index was developed to measure the changing state of the world's biodiversity over time. It uses time series data to calculate average rates of change in a large number of populations of terrestrial, freshwater and marine vertebrate species. The dataset contains about 3,000 population time series for over 1,100 species. Two methods of calculating the index are outlined: the chain method and a method based on linear modelling of log-transformed data.

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.

Progressive impact of piecemeal infrastructure development on wild reindeer »
Our results show that any further infrastructure development will put the remaining European population of wild mountain reindeer at great risk, as further habitat fragmentation will make the remaining undisturbed patches too small for holding viable populations. We discuss the importance of controlling piecemeal development in infrastructure for conservation of wildlife and argue that minimizing infrastructure development is likely one of the largest challenges in wildlife conservation ahead.
