Symbiotic relationship between gecko and insect in Madagascar

Monday, February 18th, 2008

BBC News highlighted an interesting relationship between a day gecko and a plant hopper insect in Madagascar.  Apparently the lizard signals for food which is provided by the insect.

The lizard repeatedly nods its head at the insect, called a plant hopper, until it flicks over small balls of honeydew for the gecko to dine upon.

BBC says that in return, the lizard may offer some form of protection for the plant hopper.

Non-Violence and Environmental Action

Monday, January 14th, 2008

Humpback Whale

Currently, in the Antarctic seas, Greenpeace’s ship Esperanza is chasing Japan’s whaling fleet.  Japan plans to take 900 minke whales and 50 fin whales for what they claim is scientific study, yet the whale’s final destination is Japanese restaurants and markets. 

Greenpeace believes in non-violent protest.  By chasing the whaling fleet the organization is attempting to interrupt the hunt–the Japanese cannot hunt when on the move–but not to damage the fleet.  Another environmental organization, the Sea Shepherd Conservation Society, is also pursuing the fleet, but has selected a more ‘action-oriented’ role, including in the past sinking and ramming ships, though no lives have been recorded as lost due to their actions. 

In the past century non-violent protests have proven, at times, remarkably successful.  The practice was first put in use by Gandhi (but what inspired by everything from Hinduism and Buddhism to Leo Tolstoy), then later by Martin Luther King and the People Power revolution in the Philipines.  Non-violence has been a way for people without traditional means of power–wealth, status, and/or weaponry–to create powerful change.  It is also a largely held moral and spiritual belief; those who practice non-violence believe that violent action is never acceptable and in the end solves nothing, but only begets more violence.  Non-violence may mean non-cooperation with the powers-that-be, it may mean peaceful protests and marches, or direct intervention without violence–this is what Greenpeace is doing by interfering with the Japanese whale hunt without attacking the ships or crew involved.  Non-violence also means that if one should meet violence they should do so without re-acting: turn the other cheek.  Non-violent philosophy is vast and its practitioners diverse: this is only meant as a quick sketch of the philosophy.  

Greenpeace has used non-violence from the beginning of its inception: attempting to save whales (and bringing their plight to the media) and other species, as well as preventing toxins from being dumped into the ocean etc.  Their actions have made them heroes to some, and extremists to others.  Japan has labeled them as ‘environmental terrorists’: a hyperbole if ever there was one.   

I applaud Greenpeace’s actions and its commitment to non-violence.  While the organization is not perfect, and has made mistakes in the past, it serves as a reminder of the power of non-violence to wake people up to injustice.  The difficulty that Greenpeace faces, of course, is that the injustice in not human-to-human, but human to another species and a larger ecosystem.  This requires a leap in ethical views.  Do whales have rights? And if so what are they?  Should ecosystems have rights to protect them from ourselves?  These are questions that require addressing throughout our societies.  Can we really expect to preserve any natural part of our global, to conquer such issues as global warming and mass extinction, if rights stop at homo sapiens and do not extend to the water we drink, the forests that take in the carbon and keep our riverways clean, the innumerable species that share our planet.   

As for the Sea Shepherd Conservation Society, while I understand their frustrations and agree with their mission, I do not believe in their means.  Although they have yet to murder any person, their declaration of ‘any means necessary’ (including gloating about sinking ships), not to mention their grotesque use of a Pirate skull on their flag, only harms the cause of environmentalism and protecting species.  By taking the low road, they are proving themselves not dissimilar in means from the corporate and governmental forces they oppose.  

Personally, I believe that non-violence should play a larger role in the environmental movement.  Imagine: sit-ins for endangered species, marches on Washington for sustainable energy, boycotts against unsustainable fishing practices, protests against the coal and gas industries.  By doing so organizations and individuals risk being labeled as extremists (or even terrorists).  They risk being told that they care more about other species than their own, but more and more it appears that our species is just as dependent on the health of the global environment as any other species.    Secondly, can we really reasonably argue anymore that the one species is master of the earth, while all others proves slaves to our whims?  Does human-power make human’s right? 

It appears to me that for the average citizen–who believes passionately in these issues–non-violence may be one of the best ways to affect change, whether it is changing the situation or changing minds.  At the same time, one must attempt actions that are not easily disregarded as extremist and wacko (remember being called ‘green’ used to be a dirty word).  One guy chaining himself to a tree is fodder for mockery and cynicism, a thousand people surrounding a grove marked off for another box store may not appear so nutso.  A million people marching for action on global warming in Washington may just make history. 

Things are changing.  The green movement is no longer only on the fringes.  Perhaps, now is the time for other NGOs (or individual leaders) to look to Gandhi for inspiration.  If the practice of non-violence enmasse can overthrow an empire, perhaps it can also change the way we view our world.    

     

Tasmanian devil populations severely diminished by bizarre cancer

Tuesday, January 8th, 2008

The Tasmanian devil, that iconic marsupial predator of the Australian state of Tasmania, may soon meet its end. A surprising one. Once common throughout the continent, it is believed that devils became relegated to Tasmania sometime after the introduction of the dingo to Australia by Austronesian traders 2,000-3,500 years ago. Now foxes have been intentionally and foolishly brought into Tasmania which is dealing a huge blow to the devil population. However, something else may extinguish the Tasmanian devil before the foxes ever get to it…

An extremely rare (some call it completely new) form of cancer is spreading alarmingly quickly across Tasmania, inflicting Tasmanian devils with rapidly proliferating facial tumors. The end result is death by starvation. The really bizarre part of this is that this is an infectious cancer, probably passed on as Tasmanian devils scavenge the bodies of others. This was determined when it was discovered that the disorganization of the cancerous cells’ chromosomes in multiple individuals all had pretty much identical character, and that a unique marker present in one of the devil’s normal cells was absent in its cancerous cells. This is definitely NOT normal for cancer. And extremely scary. It’s not one of those cancers that arises spontaneously in one individual and stays in that individual; it’s not even something passed genetically from generation to generation. It’s passed ambiently, spreads quickly, and kills in a matter of months. In ten years, it’s killed anywhere between 20% and 50% of all Tasmanian devils living on the island, with about 60% of the island affected. High density populations have a reported 100% mortality rate within 12-18 months. This has elevated its conservation status from “lower risk/least concern” in 1996 to in 2006 being at risk of extinction in the “medium term”.

There are a number of projects being conducted by the University of Tasmania in effort to discover more about the disease/stop it. It’s all pretty expensive, so donations are welcomed. Go to http://www.tassiedevil.com.au/help.html to find out more.

Woodlark Island Cuscus

The Woodlark islanders struggle to stop Vitroplant Ltd from logging seventy percent of their island for palm oil plantations has received new attention from organizations and media. 

The online organization forests.org has set up an action letter which anyone concerned by the issue may attach their name to have their opinion sent to 12 administrators involved.   Over two thousand people from all over the world have sent protests for Vitroplant Ltd.’s plans.  The link to the letter:

Does cryptozoology deserve its bad reputation? Probably.

Saturday, January 5th, 2008

Platypus OkapiCoelacanthHomo floresiensis Chupacabra

To almost everyone, cryptozoology does not belong in the scientific world. It relies extensively on anecdotal evidence, is known to fall headlong into hoaxes, and includes Loch Ness Monster fanatics and those people who were convinced that that poor, dead, hairless coyote was a Mexican Goat Sucker. There are thousands of online communities devoted to Bigfoot, some of which organize large expeditions into the woods which, as far as I’ve read, haven’t resulted in anything but the opportunity for these people to get together and impress each other with their expensive night-vision goggles and infrared cameras. And it’s not as if there aren’t new species to be discovered; there are tons of them - mostly insects, plants, and microscopic organisims - but cryptozoology focuses on only the pop-macrofaunal end of the spectrum, leaving the ants and mosses to others, well, more qualified.

That said, the persistence of cryptozoology (and the deep pockets of its wealthier members) has paid off more than once. The okapi, a short-necked, forest-dwelling relative of the giraffe, was regarded by Europeans as an African myth until the British governor of Uganda caught a glimpse of it in 1901.
When the platypus was discovered by Europeans in 1798, the specimens sent back to England were quickly declared fabrications; it took years of ardent persuasion for those in Australia (and fans in Europe) to convice the rest of the world that this strange little egg-laying mammal was indeed real.
The coelacanth, a massive relative of lungfish and tetrapods, was believed to have been extinct since the end of the Cretaceous until one was caught off the coast of South Africa in 1938. Since then it’s come to light that many native communities that line the eastern coast of Africa have for generations used the coelacanth for everything from a source of food to kind of sandpaper.
And then there’s Homo floresiensis, a dwarf form of Homo erectus, the discovery of whose bones on the Indonesian island of Flores in 2003 may have been foreshadowed by references to miniature people in the legends of the island’s natives.

Okapis, platypuses, coelacanths, and floresiensi all had their proponents well before their existence was proven to the world. Of course, so does the Abominable Snowman. Perhaps the lesson here is that real scientists should think about looking for the grain of truth in anecdotal evidence before disounting it altogether, and cryptozoologists should maybe, just maybe, rid themselves of crackpots stop blowing up that grain past any conceivable context.
