ZSL has been awarded funding from the Heritage Lottery Fund to save a rare species of ant from imminent extinction in England. The Red-barbed Ant is on the brink of extinction in mainland Britain; only 1 colony (all males!) is left, in Surrey, with a few more in the Isles of Scilly. A small number of ants is to be taken into captivity at London Zoo to be bred for release back into the wild. The aim is for at least 40 nests to be reintroduced each year, at several nature reserves in Surrey.
Update: 21 December 2006
The four Komodo Dragons born in April have since been proved to be the result of a virgin birth! Sungai the mother had last mated more than two years before she laid eggs following her arrival from Thoiry Zoo, in France. It was then thought that she had stored the males sperm, but subsequent genetic fingerprinting has proved that no male was involved in the production of the eggs and resulting babies.
She has subsequently mated with London Zoo's male, Raja, and produced a single `normal' baby from a small clutch of eggs. The fact that Komodo Dragons can switch back and forth between asexual and sexual reproduction, depending on the availability of a mate, was previously unknown.
Birth: 30 October 2006
