  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.

  Meeting Aichi Target 11: What does success look like for protected area systems? »

  The Convention on Biological Diversity Strategic Plan for Biodiversity 2011-2020 was adopted at the 10th Conference of the Parties in Nagoya, Japan. The plan outlines 20 Aichi Targets to achieve global biodiversity conservation. A fundamental global approach to biodiversity conservation is the use of protected areas. Arguably all 20 Aichi Targets have implications for the establishment and management of protected areas, but only Target 11 addresses them directly. This paper carries out a clause by clause analysis of Target 11 and makes recommendations to countries on interpreting each clause in order to best achieve biodiversity conservation using protected areas. Despite containing only 61 words, Target 11 is surprisingly dense. It applies to both marine and terrestrial ecosystems, and sets goals for spatial planning (representativeness, ecological connectivity and areas of importance for biodiversity); protected areas management (including management effectiveness and social equity); and criteria about what counts toward being a protected area under Target 11. The authors argue for a holistic interpretation of Target 11 as a way for the global community to use protected areas to change the current unacceptable trends in global biodiversity loss.

  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.

  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.
