  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.

  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.

  Global congruence of carbon storage and biodiversity in terrestrial ecosystems »

  Deforestation is a main driver of climate change and biodiversity loss. An incentive mechanism to reduce emissions from deforestation and forest degradation (REDD) is being negotiated under the United Nations Framework Convention on Climate Change. Here we use the best available global data sets on terrestrial biodiversity and carbon storage to map and investigate potential synergies between carbon and biodiversity-oriented conservation.

  Physiographic control on the development of Spartina marshes »

  We made a complete survey of all the extant populations in Djibouti and to collect samples for genetic analysis with a view conserving the palm for the future.
  Our survey revealed that there were a total of 314 adults, 20 juveniles, 134 rosettes, 210 small rosettes (more than 6 leaves) and 465 seedlings (<3 leaves) living in the Bankouale area of Djibouti. These are distributed unequally amongst three valley systems. 65% of the adults, 85% of the juveniles, 75% of the rosettes, 76% of the small rosettes, and 93 % of the seedlings were found in the Bankouale valley.

  Adaptation of monkey puzzle to arid environments reflected by regional differences in stable carbon isotope ratio and allocation to root biomass »

  This study demonstrates the utility of carbon isotope discrimination in describing genetic adaptation to arid environments, although it is probably most useful in detecting differentiation when the strategy of the species under investigation is to increase water use efficiency, rather than drought-avoidance. The results suggest that populations on the eastern and western sides of the Andes should be treated as separate management units for the purposes of conserving the genetic resource of this species.

  CITES and the livelihoods of the poor »

  Recent CITES decisions that accepted an obligation to take into account the impacts of CITES listings on the livelihoods of the poor, have some affinities with the ‘Do no harm’ approach to the livelihoods of the poor. The process will produce guidelines and rapid assessment tools. If these guidelines and tools are to be effective they will need to take account of the context-specific nature of solutions in this area. The CITES case provides lessons for other international conservation institutions whose activities affect the livelihoods of the poor at the local level.

  Protecting the future: carbon, forest, protected areas and local livelihoods »

  Protected areas can act as a case study for REDD: lessons can be learnt from their success or otherwise in reducing deforestation and supporting local livelihoods. Further research into the most effective management and governance frameworks for acheiving goals on carbon emissions, biodiversity and communities, and the extent to which protected areas reduce (or merely displace) deforestation within national boundaries would be useful in informing REDD implementation.

  Tracking the ecological overshoot of the human economy »

  Sustainability requires living within the regenerative capacity of the biosphere. In an attempt to measure the extent to which humanity satisfies this requirement, we use existing data to translate human demand on the environment into the area required for the production of food and other goods, together with the absorption of wastes. Our accounts indicate that human demand may well have exceeded the biosphere's regenerative capacity since the 1980s. According to this preliminary and exploratory assessment, humanity's load corresponded to 70% of the capacity of the global biosphere in 1961, and grew to 120% in 1999.
