Rarest dog: Ethiopian wolves are genetically vulnerable

Populations of the world's rarest dog, the Ethiopian wolf, are genetically fragmenting, scientists say.

Fewer than 500 of Africa's only wolf species are thought to survive. Now a 12-year study of Ethiopian wolves living in the Ethiopian highlands has found there is little gene flow between the small remaining populations. That places the wolves at greater risk of extinction from disease, or habitat degradation. In a study published in the journal , Dada Gottelli of the Zoological Society of London and colleagues in Oxford, UK and Berlin, Germany, quantified the genetic diversity, population structure and patterns of gene flow among 72 wild-living Ethiopian wolves.

Scientists say billions required to meet conservation targets

The most threatened species tend to be relatively cheap to save because of small range sizes.

Reducing the risk of extinction for threatened species and establishing protected areas for nature will cost the world over $76bn dollars annually. Researchers say it is needed to meet globally agreed conservation targets by 2020. The scientists say the daunting number is just a fifth of what the world spends on soft drinks annually. And it amounts to just 1% of the value of ecosystems being lost every year, they report in the journal Science.
