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 PapersThis database was created and is maintained by UNEP-WCMC with financial support from the European Commission and the Joint Nature Conservation Committee of the United Kingdom.
It contains nomenclatural, distribution and legal data on CITES-listed species.
This information resource is a result of long-term collaboration between countless individual scientists worldwide and many organizations whose contribution is gratefully acknowledged.
Resource Type: Tools / ApplicationsThe Critical Site Network (CSN) Tool is a new online resource for the conservation of 294 species of waterbirds and the important sites upon which they depend in Africa and Western Eurasia. Leading global conservation organisations working for the protection of waterbirds and their habitats have joined forces to develop this tool, strengthening the implementation of the African-Eurasian Migratory Waterbird Agreement (AEWA) and the Ramsar Convention on Wetlands.
Resource Type: Tools / ApplicationsThe CITES Trade Database, managed by UNEP-WCMC on behalf of the CITES Secretariat, is a unique resource that holds over 11 million records of trade in wildlife and over 50,000 scientific names of taxa listed by CITES. Contracting Parties provide annual reports to the CITES Secretariat including full details of all export and import permits and certificates issued during the previous year. More than 850,000 records of trade in CITES-listed species of wildlife are reported annually.
Resource Type: Tools / ApplicationsA 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.
Resource Type: Journal PapersThese posters were designed to highlight the work of the 'Wings over Wetlands' project of the AEWA Convention - Agreement on the Conservation of African-Eurasian Migratory Waterbirds.
Resource Type: PostersSince about 1600, 486 animal species have been recorded extinct. This represents about 0.04 of all animal species so far described. In the same period, 600 plant species are known to have disappeared, about 0.25 of the total. These figures are much smaller than those of the Permian/Triassic and Cretaceous/Tertiary mass extinctions. One might therefore conclude that at present life on earth is at comparatively little risk of extinction. However, there is a growing body of data to show that the converse is true.
Resource Type: Journal PapersThe CITES Trade Data Dashboards are a new, interactive and dynamic way of viewing the trade data submitted by CITES Parties in their annual reports to the Convention. The Global dashboard displays global trade trends (e.g. global trade in live reptiles), whereas the National dashboard shows information by country. The dashboards have been developed by UNEP-WCMC on behalf of the CITES Secretariat.
Resource Type: Tools / ApplicationsThese posters were designed to publicise the release of the World Atlas of Great Apes and their Conservation.
