IUCN Red List Criteria for EndangeredLast Updated on 2014-07-07 17:50:39The IUCN Species Program working with the IUCN Species Survival Commission (SSC) has for more than four decades been assessing the conservation status of species, subspecies, varieties, and even selected subpopulations on a global scale in order to highlight taxa threatened with extinction, and therefore promote their conservation.
The IUCN Red List of Threatened Species provides taxonomic, conservation status and distribution information on plants and animals that have been globally evaluated using the IUCN Red List Categories and Criteria. This system is designed to determine the relative risk of extinction, and the main purpose of the IUCN Red List is to catalog and highlight those plants and animals that are facing a higher risk of global extinction (i.e. those listed as Critically Endangered, Endangered and Vulnerable). The IUCN Red List also includes information on... More »

Metapopulation dynamics of wild dogs in South AfricaLast Updated on 2014-07-02 13:56:37
Ideally, species should be protected in areas large enough to allow for natural demographic and genetic processes. However, in realty, species often occur in small and isolated patches of suitable habitat embedded in human-dominated landscapes. In metapopulation ecology, landscapes are viewed as networks of habitat patches (fragments) in which species occur as discrete local populations connected by migration. The dynamics of such a metapopulation is characterised by (asynchronous) local extinction and recolonisation events.
However, human modification of the landscape between habitat patches, the so-called matrix, often prevents migration. While establishing ‘corridors’ through the matrix may allow dispersing individuals to move from one habitat patch to another, this is often problematic in practice. This raises the question of how metapopulation viability can be... More »
