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 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: ReportsIndigenous and Community Conserved Areas (ICCAs) are managed areas that are voluntarily conserved by local or indigenous communities for conservation and cultural purposes. This handbook is intended as a guide for those who wish to learn about ICCAs and the newly developed ICCA Registry tool, which aims to develop awareness, recognition and documented values of ICCAs through a community-supported database, maps and an interactive, multimedia website. Communities who govern and manage ICCAs will find this handbook particularly helpful to understand how they can contribute to and benefit from the Registry if they wish. This handbook adheres to the UN Declaration on the Rights of Indigenous Peoples and supports the application of bio-cultural community protocols in maintaining the integrity of community knowledge and resources.
Resource Type: ReportsThe IUCN Summit on Protected Area Management Categories was held in Almeria, Spain in May 2007. It aimed to test the opinions of key thinkers and policy makers regarding the revision of guidelines to interpretation of the six IUCN protected area categories. The meeting was generously supported by the Junta de Andalusia, the Spanish Ministry of Environment and the foundation Biodiversidad. The meeting operated through plenary sessions and a series of specialised workshops, with many presentations and time for detailed discussion. There were two field trips, midway through the meeting and at the end. More than a hundred people attended from over fifty countries around of the world.
Resource Type: ReportsThis study reviews the biogeographic and biodiversity coverage of the current World Heritage network and identifies broad gaps. It also identifies priority sites for biodiversity conservation that may merit World Heritage listing in the future and reviews how these could help fill the existing gaps in the network.
Resource Type: ReportsOver the past 10 years a number of studies and consultations have been carried out to develop and refine the Global Strategy for achieving a balanced, representative and credible World Heritage List that reflects the world’s diverse heritage. This review is an important addition to that process, focusing on the inter-related elements of biogeography, habitats and biological diversity that underpin much of what we consider ‘natural heritage’.
Resource Type: ReportsGeographical range is considered a good predictor of the levels of isozyme variation in plants. Widespread species, often consisting of historically larger and more continuous populations, maintain higher polymorphism and are less affected by drift, which tends to erode genetic variation in more geographically restricted species. However, widespread species occurring in small and disjunct populations may not fit this pattern. In this study we examined genetic variation in Pilgerodendron uviferum, a conifer endemic to temperate forests of southern South America.
Resource Type: Journal PapersUNEP-WCMC produces reports for a number of fora including CITES, the European Commission and the Convention on the Conservation of Migratory Species of Wild Animals (CMS). Recent examples of these reports can be downloaded here in PDF format.
Resource Type: ReportsStipitate hydnoid ('tooth') fungi are considered to be threatened throughout much of central and northern Europe. In response to concern about the status of these fungi in the UK, a Biodiversity Action Plan has been developed for 14 species in this group. As a first step towards implementation of this plan, a number of surveys have been initiated, to determine the current status and distribution of hydnoid fungi. An overview of the results of these surveys is described. A series of distribution maps are presented, based on a compilation of early records and the results of a recent field survey in Scottish coniferous forests. The difficulties of interpreting early records are discussed, with particular reference to the taxonomie confusion that has surrounded this group of fungi. Although available data provide little evidence for decline of hydnoid fungi, a number of species display very restricted distributions within Scotland. The recent discovery of several species new to Britain emphasises the need for further field surveys to define the current status of these fungi with greater accuracy.
