UK ecologists have new insights about how diseases jump the species barrier from wildlife to humans. With a global survey of land use and biodiversity, they鈥檝e discovered that when natural habitats are converted to farmland or urbanised, the animal species that survive the change in greatest number are those species which carry viruses and bacteria with the potential to spread to us. This is particularly the case, says Rory Gibb of the University College London, with disease-carrying rodent species, bats and birds.
