50 new animal species astonish conservationists

A BRIGHT-GREEN tree frog with huge black eyes, jumping spiders and a striped gecko are among more than 50 new animal species scientists have discovered in a remote, mountainous region of Papua New Guinea.

The discoveries were announced yesterday by Washington DC-based Conservation International, which spent the past several months analyzing more than 600 species the group found during its expedition to the South Pacific island nation last summer.

Of the discoveries, 50 spider species, three frogs and a gecko appear to have never been described in scientific literature before.

The new frogs include a tiny brown animal with a sharp chirp, a bug-eyed bright-green tree frog and another frog with a loud ringing call. One of the jumping spiders is shiny and pale green, while another is furry and brown.

"If you're finding things that are that big and that spectacular that are new, that's really an indication that there's a lot out there that we don't know about," said expedition leader Steve Richards. "It never ceases to amaze me the spectacular things that are turning up from that island."

The findings are significant, particularly the discovery of the new frog species, said Craig Franklin, a zoology professor at The University of Queensland in Australia.

"They're often regarded as a great bioindicator of environmental health," said Franklin. "Often we see declines in frogs as a direct pointer to an affected environment."

Researchers from Conservation International explored the region with scientists from the University of British Columbia in Canada and Montclair State University in New Jersey, as well as local scientists from Papua New Guinea.

The area explored provides a critical source of clean drinking water to tens of thousands of people living in surrounding communities, and local clans rely on the region for hunting.

Montclair State University anthropologist William Thomas worked with the local Hewa clan to document the area's resources during the expedition as part of a project he started with scientist Bruce Beehler of Conservation International.

Conservation International plans to conduct three more expeditions to Papua New Guinea this year, in the hopes of turning up even more new animals.

"Most of us live in urban worlds where we think everything's totally well known," Beehler said.

"It's a little bit of a reminder, just a wake up call, that we really need to know our world better so we can manage it better."
