An assessment of impacts on Arctic terrestrial ecosystems has emphasized geographical variability in responses of species and ecosystems to environmental change. This variability is usually associated with north-south gradients in climate, biodiversity, vegetation zones, and ecosystem structure and function. It is clear, however, that significant east-west variability in environment, ecosystem structure and function, environmental history, and recent climate variability is also important.Some areas have cooled while others have become warmer.
Overall, the subregional synthesis demonstrates the difficulty of generalizing projections of responses of ecosystem structure and function, species loss, and biospheric feedbacks to the climate system for the whole Arctic region and implies a need for a far greater understanding of the spatial variability in the responses of terrestrial arctic ecosystems to climate change.Resource Type: Journal Papers
The International Waterbird Census (I WC), coordinated by Wetlands International, provides a framework for monitoring non-breeding populations at a global scale. However, wader counts are not yet available from most countries for enough years to allow meaningful population trend analyses. Nevertheless there is considerable potential for trend analyses using IWC data in the future. Many other studies use different and uncoordinated methods. We still lack facilities for broad-scale analyses which would allow the reasons for observed changes in wader populations to be explored. A GIS referenced, decentralised, web-based database interface is proposed which would help explain these changes by linking wader m onitoring initiatives, and by providing integration with other environmental monitoring schemes.Resource Type: Journal Papers
Chapter from STATUS AND TRENDS OF, AND THREATS TO, MOUNTAIN BIODIVERSITY, MARINE, COASTAL AND INLAND WATER ECOSYSTEMS: abstracts of poster presentations at the eighth meeting of the Subsidiary Body on Scientific, Technical and Technological Advice of the Convention on Biological Diversity.Resource Type: Reports
Governments are often accused of responding only to short-term and parochial considerations. It is therefore remarkable that representatives of 190 countries recently committed themselves at the Convention on Biological Diversity to reducing biodiversity loss. This presents conservation biologists with perhaps their greatest challenge of the decade. The authors of this Policy Forum describe approaches to identifying more of the earth's biological diversity; understanding how biological, geophysical, and geochemical processes interact; and presenting scientific knowledge in time to contribute to and achieve the 2010 target.Resource Type: Journal Papers
To maintain the greatest resilience of Amazonian biodiversity to climate change as modelled by HADCM2GSa1, highest priority should be given to strengthening and extending protected areas in western Amazonia that encompass lowland and montane forests.Resource Type: Journal Papers
Several of the regional and global biodiversity-related agreements relate to similar topics and themes. Based on this assumption, a more coherent approach towards implementation of the biodiversity commitments could be enhanced if structured information on issues of common concern to different MEAs is made available to national focal points and other actors.Resource Type: Journal Papers
140 pages of tabular data with supporting text and graphics, on global biodiversity. Topics are covered in a concise way, using tables supported by minimal text and graphics. They include country species diversity, threatened species, national Red Data Books, major food crops, domestic livestock, marine resources, tropical forests, protected areas and systematics collections.Resource Type: Reports
The threatened Chilean conifer Podocarpus salignus D. Don is currently the focus of ex situ conservation eorts being undertaken by the Conifer Conservation Programme of the Royal Botanic Garden Edinburgh. To assess variation within in and ex situ populations of the species, leaf material collected from four wild populations was analysed by random amplified polymorphic DNA (RAPD).
RAPD was found to be an effective tool for assessing the genetic structure of P. salignus, for providing a guide to future germplasm-sampling strategies, and for hybrid identification. Implications for genetic conservation of the species and the role of ex situ approaches are discussed.Resource Type: Journal Papers
UNEP-WCMC, in collaboration with SNV in Viet Nam, has developed a briefing on participatory biodiversity monitoring in REDD+. Some national REDD+ programmes, including Viet Nam’s, are currently considering the use of participatory biodiversity monitoring within REDD+. This brief presents the key issues that national REDD+ programmes may want to consider if they decide to develop participatory biodiversity monitoring. The briefing covers why monitor biodiversity in REDD+, what is participatory biodiversity monitoring, what are the concerns about participatory biodiversity monitoring, and what is needed for participatory biodiversity monitoring.
Overall, participatory biodiversity monitoring can benefit REDD+ programmes as a relatively cost-effective and sustainable component of national forest monitoring systems. Monitoring biodiversity impacts of national programmes, including REDD+ can provide information on how countries are achieving the objectives of multilateral environment agreements, and existing national policies. In particular, safeguard information systems for national REDD+ programmes can benefit from the information provided by participatory biodiversity monitoring approaches. Additionally, participatory biodiversity monitoring can empower and encourage local stakeholder engagement in REDD+ processes and contribute to the full and effective participation of stakeholders, in particular women, indigenous peoples and local communities. REDD+ schemes that can demonstrate biodiversity benefits may be more attractive to gain support for the actions. However, participatory biodiversity monitoring is likely not to be the best solution in situations where complex equipment or expertise is needed to collect the data or where abstract indices of biodiversity are applied.Resource Type: Reports
Protected areas are one of the cornerstones for conserving the world's remaining biodiversity, most of which occurs in tropical forests. We use multiple sources of satellite data to estimate the extent of forest habitat and loss over the last 20 years within and surrounding 198 of the most highly protected areas (IUCN status 1 and 2) located throughout the world's tropical forests. In the early 1980s, surrounding habitat in the 50-km unprotected or less highly protected 'buffers' enhanced the protected areas' effective size and their capacity to conserve richness of forest-obligate species above the hypothetical case of complete isolation. However, in nearly 70 of the surrounding buffers, the area of forest habitat declined during the last 20 years, while 25 experienced declines within their administrative boundaries.Resource Type: Journal Papers
