As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

Biologist reveals important role cities play in conservation of threatened species

The exhaustive international trade of wildlife has pushed many species to the brink of extinction. Coincidentally, many of the same species have been introduced to urban centres or wilderness areas outside their natural ranges. In a recent study published in Frontiers in Ecology and the Environment, authors from Hong Kong and Australia find that these introduced populations may provide hope for these threatened species.

"Across the planet, poachers have reached into the last remote habitats to harvest wildlife populations used for clothing, eaten, or kept as pets in faraway cities," said Dr. Luke Gibson from the School of Biological Sciences of the University of Hong Kong, who led the study.

"In some cases, the traded organisms have escaped and are now thriving in their introduced habitats," he added.

In total, the authors identified 49 globally threatened species -- those listed by the International Union for the Conservation of Nature as Vulnerable, Endangered, or Critically Endangered -- which have established introduced populations outside their native distribution. These include amphibians, reptiles, mammals, and birds, as well as insects and plants, with introduced populations found on all continents except Antarctica.
