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.Resource Type: Journal Papers
This paper reviews the potential for carbon sequestration in dryland ecosystems, which includes forests, but also covers other habitats, such as grasslands, and, importantly, soils. It also considers ways in which carbon storage in drylands affects land degradation issues.Resource Type: Reports
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.Resource Type: Journal Papers
How may we improve the quality, accessibility and usefulness of data about the living world? Three examples present themselves: use of new technology to build capacity for biodiversity knowledge management in the developing world; engagement of new sources of data; and harmonization of official data deriving from inter-governmental biodiversity-related treaties.Resource Type: Journal Papers
This synthesis focuses on estimates of biodiversity change as projected for the 21st century by models or extrapolations based on experiments and observed trends. The term “biodiversity” is used in a broad sense as it is defined in the Convention on Biological Diversity to mean the abundance and distributions of and interactions between genotypes, species, communities, ecosystems and biomes. This synthesis pays particular attention to the interactions between biodiversity and ecosystem services and to critical “tipping points” that could lead to large, rapid and potentially irreversible changes. Comparisons between models are used to estimate the range of projections and to identify sources of uncertainty. Experiments and observed trends are used to check the plausibility of these projections. In addition we have identified possible actions at the local, national and international levels that can be taken to conserve biodiversity. We have called on a wide range of scientists to participate in this synthesis, with the objective to provide decision makers with messages that reflect the consensus of the scientific community and that will aid in the development of policy and management strategies that are ambitious, forward looking and proactive.Resource Type: Reports
We briefly review recent global trends in habitat area in as many broadly-defined natural habitats as possible, and in indices of animal populations characteristic of those habitats. The information available indicates continuing declines in habitat area and species, but those data are extremely sparse.Resource Type: Journal Papers
The third edition of Global Biodiversity Outlook (GBO-3) summarizes the latest data on status and trends of biodiversity and draws conclusions for the future strategy of the Convention. GBO-3 is based on a range of information sources, including National Reports, biodiversity indicators information, scientific literature, and a study assessing biodiversity scenarios for the future.Resource Type: Reports
The number of environmental variables used during modelling could affect the outcome, but we found no correlation between these and our estimates of extinction risk in global samples. Although further investigation is needed, it is unlikely to result in substantially reduced estimates of extinction. Anthropogenic climate change seems set to generate very large numbers of species-level extinctions.Resource Type: Journal Papers
We suggest that well-targeted instruments that consider contextual information, such as conservation status, are the most effective and efficient approach to monitoring international wildlife trade for conservation purposes. Where relevant, such instruments could be expanded to include additional species not currently protected, or new instruments could be developed to monitor certain groups as appropriate.Resource Type: Journal Papers
National Parks and other protected areas not only provide a safe haven for biodiversity, they provide benefits to local communities and preserve some of the most beautiful places on our planet. ‘Coverage of protected areas’ is also a specific indicator in the 2010 Target of the Convention on Biological Diversity.
Obtaining the data necessary to monitor trends in protected areas requires a massive effort by national authorities to compile, analyse and then distribute this data to the centralised depository of the World Database on Protected Areas (WDPA). With a living and growing system of protected areas that now exceed 100,000 sites covering 19 million square kilometres, you can imagine that this is no small task!
