Patterns of Extinction and Perception of Corruption

Professor Ian Owens, one of the paper’s authors from Imperial College London’s Division of Biology, and the Natural Environment Research Council’s Center for Population Biology, said: “For the first time ever this global mapping has divided the planet up into small grid squares to obtain a really detailed picture of biodiversity. By looking at the numbers of endangered mammals, birds and amphibians in these squares, we have been able to see how this real picture varies from assumptions that have previously been made about global biodiversity of endangered species.”

Professor Owens adds that this geographical discrepancy in hotspots of endangered species from different groups can be explained by the different factors that threaten mammals, birds and amphibians: “Endangered bird species are often at risk because their habitats are being destroyed. However, different factors entirely may affect mammals such as tigers which are under threat from poachers, and amphibians which are being diminished by diseases brought into their habitat by non-native fish.

These are two different links.

Explanatory notes*

* CPI Score relates to perceptions of the degree of corruption as seen by business people and country analysts, and ranges between 10 (highly clean) and 0 (highly corrupt).

** Confidence range provides a range of possible values of the CPI score. This reflects how a country’s score may vary, depending on measurement precision. Nominally, with 5 percent probability the score is above this range and with another 5 percent it is below. However, particularly when only few sources are available, an unbiased estimate of the mean coverage probability is lower than the nominal value of 90%.

*** Surveys used refers to the number of surveys that assessed a country’s performance. 12 surveys and expert assessments were used and at least 3 were required for a country to be included in the CPI.
