World’s largest butterfly disappearing from Papua New Guinea rainforests

Rare Queen Alexandra’s birdwing is losing habitat to logging and oil palm plantation

How large does a butterfly have to be before anybody notices it is disappearing? In the case of Papua New Guinea‘s (PNG) Queen Alexandra’s birdwing, the answer is enormous.

The world’s largest butterfly boasts a 1ft (30cm) wingspan – imagine the width of a school ruler – yet few outsiders in its rainforest home in Oro province in northern PNG have ever seen it. It’s a scenario unlikely to improve as oil palm plantation and logging remorselessly devours this endangered butterfly’s habitat.

Edwardian naturalist Albert Meek first recorded it in 1906 on a collecting expedition to PNG. The fast-flying butterfly frequents high rainforest canopy so Meek resorted to blasting them down by shotgun. The Natural History Museum taxonomically allocated his buckshot-peppered specimens into the birdwing genus (a tropical grouping possessing super-elongated forewings) and named it after Edward VII’s wife.

How does mimicry work in butterflies? Academy researcher Durrell Kapan and his colleagues have found the answer in the butterfly’s genome: here.

Economy of arm autotomy in the mesopelagic squid Octopoteuthis

Octopoteuthis deletron autotomizes 2 arms onto a bottle-brush that is attached to an arm of the remotely operated vehicle (ROV) ‘Ventana’ on October 22, 2008, at 830 m depth. The 2 arms remain attached to the bottle-brush, and then 1 arm detaches and thrashes for 10 s before ceasing movement. The terminal photophore of the thrashing arm is white, therefore it is presumably bioluminescent (Video 1).

Abstract

Remotely operated vehicles (ROVs) were used to observe and collect the mesopelagic squid Octopoteuthis deletron Young, 1972. I documented numerous individuals with shortened, blunt-ended arms and regenerating arm-tips, which may be indicative of arm autotomy, i.e. the jettisoning of a body part as a defense. To test the hypothesis that O. deletron is capable of arm autotomy, laboratory investigations and an in situ experiment using ROVs attempted to induce autotomy. I looked for autotomy fracture planes in histologically sectioned arms. O. deletron is capable of arm autotomy, but it requires traction to occur. O. deletron has numerous places where an arm can sever; arm breakage always occurred immediately proximal to the point of interaction, minimizing tissue loss, and demonstrating ‘economy of autotomy’. Despite the fact that this species can autotomize an arm anywhere along its length, only a few well-defined fracture planes were found in our histological sections, indicating that autotomy probably occurs via loss of tensile strength during a defensive interaction. In O. deletron, an autotomized arm usually thrashes and the terminal arm photophore bioluminesces—whether a steady glow, flashing on and off, or both—which could be an important part of predator distraction associated with autotomy in dark, mesopelagic waters. O. deletron is the first squid reported to autotomize its arms, the only cephalopod known to be capable of economy of autotomy, and is one of very few species known to use attack autotomy, whereby a predator is grasped by a body part that is subsequently autotomized.

Iran cheetah research

Iran’s cheetah brothers roaming far and wide in search of food and a mate

Cheetah “brothers” Are Now in Ariz

July 2012. Born in Iran’s Siahkouh National Park in the spring of 2010, two cheetah siblings are now roaming in the zone known as the ‘Ariz No Hunting Area‘ in central Iran. After losing a sibling during their first few months, the cheetahs, accompanied by their mum, walked more than 130 kilometres through vast deserts of central Iran to arrive in Dare Anjir Wildlife Refuge in summer 2011.

Since last winter, they have dispersed southward and now they are ranging in Ariz, a newly established reserve just south of Dare Anjir. After the brothers became independent from their mum, they departed Dare Anjir and returned 130 kilometres (at least) back to Siahkouh.

In the meantime, the “brothers” who roamed most of Dare Anjir (1750 km2), and occasionally even outside of the reserve boundary during the last winter, were sometimes joined by another probably un-related young male to form a coalition of three males. However, camera traps indicate that their coalition was not stable during winter, and sometimes the new male preferred a solitary life.

Tortured Tamil political prisoner interviewed

WSWS interviews tortured Tamil political refugee

30 July 2012

In April and May of 2009, the war waged by successive Sri Lankan governments since 1983 against the separatist Liberation Tigers of Tamil Eelam (LTTE) was coming to its brutal end with the crushing of the latter by the army.

President Mahinda Rajapakse’s government and its military intelligence, aided by Tamil paramilitary groups, began round-ups in the internally displaced persons (IDP) camps of anyone who had “even a small connection” with the LTTE.

More than 11,000 Tamils were arrested, many of them women and youth. After a few days of screening in IDP camps, they were separated and given minutes to gather their belongings before being sent to so-called rehabilitation centres.

According to the government, 5,000 of these prisoners have been released. But they remain under close military surveillance. More than 6,000 people are still in secret camps and the so-called rehabilitation centres. They have not been charged with any crime, but most have been in detention since the end of the war. Under the Prevention of Terrorism Act (PTA), political prisoners in Sri Lanka can be held indefinitely without trial.

In May 2009, President Rajapakse boasted that the war was over and “LTTE terrorism” had been eliminated, but the arrests of “LTTE suspects” continue in the north and east, which are under military occupation. Last April 21, in the Trincomalee district, the security forces rounded up around 160 Tamil males and females from their houses for questioning. Thirty-eight people were detained under the PTA. They will be put through a year-long process known as “rehabilitation”.

Amnesty International reported on March 14, 2012: “People released from detention have remained under surveillance by intelligence forces. The Sri Lankan Army continues to have a large presence in the north and is deployed for civil policing. The Special Task Force (STF), an elite police commando unit with a history of human rights violations, remains active across the country. Former detainees have been harassed and rearrested, and physically attacked. Killings and enforced disappearances of newly released detainees have also been reported”.

Last week, WSWS reporters in Paris interviewed a former Tamil political prisoner, now 28. A few months ago, to save his life, he came to Europe as a political refugee. For security reasons we do not give his name. He was held in several different “rehabilitation” centres.
