Brazilian researchers are turning to cloning to help fight the perilous decline of several animal species. The scientists at Brazil's Embrapa agriculture research agency said this week they have spent two years building a gene library with hundreds of samples from eight native species, including the collared anteater, the bush dog, the black lion tamarin, the coati, and deer and bison varieties, as well as the leopard and the maned wolf, according to team leader Carlos Frederico Martins.
