Scientists discover 8 new species

,

By ARON HELLER, Associated Press Writer

JERUSALEM - Israeli scientists have discovered an ancient ecosystem containing eight previously unknown species in a lake inside a cave, where they were completely sheltered from the outside world for millions of years.

The newly discovered crustaceans and invertebrates were found last month in a cave near the city of Ramle in central
Israel, team leader Amos Frumkin announced Thursday.

"This is a very unique ecosystem that is completely isolated from the surface," said Frumkin, a cave researcher in the geography department of Hebrew University in Jerusalem.

The cave, located 328 feet below ground in a limestone quarry, includes tunnels that extend about a mile and a half. Inside, a large underground lake holds the previously unknown species, some similar to scorpions and shrimp.

Allen G. Collins, a research fellow at the
Smithsonian Institution in Washington, said the find "underscores how little we know about life on our planet and how important it is to keep looking."

"I imagine this is a unique situation, to have a cave system with both marine and freshwater systems, and it is quite interesting in an underground situation," he said. "The scorpion-like creatures as well as the shrimp-like creatures that were found are unique."

The animals had been completely sheltered from the outside world by a thick layer of chalk that was impenetrable to water or exterior nutrients, Frumkin said.

Aside from one scorpion-like creature, all other species discovered were found alive. None were more than two inches long.

Frumkin said similar caves have been discovered in Romania and Mexico, but none were as isolated. Unlike most animals, which depend on the photosynthesis food chain, the newly discovered species live off a completely independent and self-sustaining ecosystem.

Israel Naaman, Frumkin's research assistant, made the initial discovery. He had been conducting a survey of caves when he came across a small hole that just kept growing.

"I thought it was just a small hole and I couldn't believe what I had found; surprise after surprise," he said.

When one of the volunteer staff crouched down to measure the temperature of the warm, sulfuric water he suddenly jumped up and yelled "there is something moving here."

Naaman acknowledged the species were likely endangered from oxygen exposure during the discovery process but said he was confident in the scientific importance of the find. He said he believes further exploration will reveal additional new life forms.

The Israeli researchers have shared their findings with international experts for further review and classification and hope to publish their conclusions soon.

The limestone cave is believed to be the second-largest in Israel. In order to explore it, researchers had to climb ropes and crawl through most of it. Due to its scientific significance and the fact that it is located inside an active quarry, the cave is now closed to visitors.

Science team finds 'lost world'

, ,

An international team of scientists says it has found a "lost world" in the Indonesian jungle that is home to dozens of new animal and plant species.

"It's as close to the Garden of Eden as you're going to find on Earth," said Bruce Beehler, co-leader of the group.

The team recorded new butterflies, frogs, and a series of remarkable plants that included five new palms and a giant rhododendron flower.

The survey also found a honeyeater bird that was previously unknown to science.

The research group - from the US, Indonesia and Australia - trekked through an area in the mist-shrouded Foja Mountains, located just north of the vast Mamberamo Basin of north-western (Indonesian) New Guinea.

The researchers spent nearly a month in the locality, detailing the wildlife and plant life from the lower hills to near the summit of the Foja range, which reaches more than 2,000m in elevation.

"It's beautiful, untouched, unpopulated forest; there's no evidence of human impact or presence up in these mountains," Dr Beehler told the BBC News website.

"We were dropped in by helicopter. There's not a trail anywhere; it was really hard to get around."

He said that even two local indigenous groups, the Kwerba and Papasena people, customary landowners of the forest who accompanied the scientists, were astonished at the area's isolation.

"The men from the local villages came with us and they made it clear that no one they knew had been anywhere near this area - not even their ancestors," Mr Beehler said.

Unafraid of humans

One of the team's most remarkable discoveries was a honeyeater bird with a bright orange patch on its face - the first new bird species to be sighted on the island of New Guinea in more than 60 years.

The researchers also solved a major ornithological mystery - the location of the homeland of Berlepsch's six-wired bird of paradise.


First described in the late 19th Century through specimens collected by indigenous hunters from an unknown location on New Guinea, the species had been the focus of several subsequent expeditions that failed to find it.

On only the second day of the team's expedition, the amazed scientists watched as a male Berlepsch's bird of paradise performed a mating dance for an attending female in the field camp.

It was the first time a live male of the species had been observed by Western scientists, and proved that the Foja Mountains was the species' true home.

"This bird had been filed away and forgotten; it had been lost. To rediscover it was, for me, in some ways, more exciting than finding the honeyeater. I spent 20 years working on birds of paradise; they're pretty darn sexy beasts," Dr Beehler enthused.

The team also recorded a golden-mantled tree kangaroo, which was previously thought to have been hunted to near-extinction.

Mr Beehler said some of the creatures the team came into contact with were remarkably unafraid of humans.

Two long-beaked echidnas, primitive egg-laying mammals, even allowed scientists to pick them up and bring them back to their camp to be studied, he added.

The December 2005 expedition was organised by the US-based organisation Conservation International, together with the Indonesian Institute of Sciences.

The team says it did not have nearly enough time during its expedition to survey the area completely and intends to return later in the year.

The locality lies within a protected zone and Dr Beehler believes its future is secure in the short term.

"The key investment is the local communities. Their knowledge, appreciation and oral traditions are so important. They are the forest stewards who will look after these assets," Dr Beehler told the BBC.

A summary of the team's main discoveries:
A new species of honeyeater, the first new bird species discovered on the island of New Guinea since 1939
The formerly unknown breeding grounds of a "lost" bird of paradise - the six-wired bird of paradise (Parotia berlepschi)
First photographs of the golden-fronted bowerbird displaying at its bower.
A new large mammal for Indonesia, the golden-mantled tree kangaroo (Dendrolagus pulcherrimus)
More than 20 new species of frogs, including a tiny microhylid frog less than 14mm long
A series of previously undescribed plant species, including five new species of palms
A remarkable white-flowered rhododendron with flower about 15cm across
Four new butterfly species.
