More on the European Bushmeat trade, including where the markets are in Paris, and some solutions to curbing the problem. Also am thinking DNA analysis could help with species ID and/or these seizures could be useful for doing poaching pressure analyses on certain areas as has been done with whales and other species - MA

Is That an Alligator in Your Suitcase?
by SHARON BEGLEY (June 18, 2010)
To the dismay of environmentalists, European tourists delight in smuggling black-market bushmeat.

Scientists estimate nearly 12,000 pounds of illegal bushmeat are smuggled into France from Africa every week, and the threat to endangered species is only getting worse.

An undeclared bottle of whiskey, a string of pearls bought on vacation and hidden inside a bra in the suitcase—sure, customs inspectors see that every day. But a nice haunch of crested porcupine? Some fresh cane rat or long-tailed pangolin? Red-river hog or Nile crocodile? Not so much.

But maybe customs agents at international airports should start looking more often. When Anne-Lise Chaber of the Zoological Society of London spent two and a half weeks with customs inspectors assigned to flights originating in sub-Saharan Africa and landing at Paris’s Roissy-Charles de Gaulle airport in June 2008, she found that bushmeat—the meat of wild animals—was being illegally brought in at an astonishing rate. Inspecting just 134 passengers arriving on 29 Air France flights (out of about 180 flights in all during the 18 days of the study, with a capacity of about 17,000 passengers per week), agents found 414 pounds of bushmeat and 288 pounds of livestock—including a nicely wrapped whole sheep and calves nestled in carryalls.

Conservation biologists have previously sounded the alarm about illegal sales of bushmeat by and to Africans living in Europe and the United States—Africans living abroad apparently want a taste of home just as Americans living overseas need their pizza fix—but the scope of the problem on a daily basis had never before been documented.

Chaber and her ZSL colleagues therefore decided to watch over the shoulders of the customs agents as they performed random inspections on passengers arriving from Africa. (To be precise, the inspections were random except in the case of passengers carrying ice chests, who were all chosen for scrutiny.) It was a grisly picture, and not only because among the contraband were the aforementioned sheep and calves. Based on this sample, the scientists estimate that 5 metric tons (11,550 pounds) of bushmeat is being smuggled into Paris from Africa every week, with Cameroon (8,000 pounds), the Central African Republic (2,100 pounds), and the Republic of Congo (1,300 pounds) the chief offenders. “We were surprised by the estimated volumes—5 tonnes” [11,000 pounds] per week, Marcus Rowcliffe of the ZSL told me by e-mail. And with one passenger “carrying 51 kg [112 pounds] of bushmeat and no other luggage, strongly suggesting a link with trade rather than personal use,” it is clear that supplying bushmeat to the African diaspora is a thriving concern.

It also poses a serious threat to endangered species. After years in which conservationists focused on the loss of habitat as a chief reason for the disappearance of species, it has become clear that illegal hunting is taking a horrific toll on tropical wildlife populations. (NEWSWEEK described this growing threat in a 2007 cover story on the poaching of mountain gorillas in Congo, and in a 2008 story on “the extinction trade.” “While there is anecdotal evidence of international trade in bushmeat, including seizures of African bushmeat at airports, and the occasional prosecution of traders in European cities, it is a neglected aspect of the issue,” Rowcliffe and his collaborators write in the current issue of the journal Conservation Letters.

It is also against the law. The European Union prohibits passengers arriving in Europe from carrying any meat or meat products, partly because they may harbor pathogens but also because of the threat it poses to endangered wildlife. Yet despite this ban, the ZSL scientists could have opened their own butcher shop with what the customs agents found. (As it was, much of the bushmeat carried for sale rather than personal use was apparently destined for the market near Château Rouge station on Rue des Poissonniers in Paris, where middle-aged bushmeat is sold in the open. Prices: €20 and €30 per kilogram—or $11 to $13.50 per pound—for primate, crocodile, cane rat, and porcupine.)

The bushmeat arrived dressed and often smoked, which made identification a challenge. Although the pangolins, porcupines, and cane rats were obvious, the monkeys had to be identified by skeletal analysis. “But even then we were only able to identify the monkeys to genus level,” says Rowcliffe: guenons (Cercopithecus sp.) or mangabeys (Cercocebus sp.). All species in these genera are listed as endangered or threatened by the Convention on International Trade in Endangered Species (CITES), which means that international trade in these creatures is banned or highly restricted—and in any case, illegal for individual airline passengers. Trade in the Nile croc and slender-snouted croc is also banned, while trade in the blue duiker and pangolins is restricted, yet there they all were. All told, 39 percent of the bushmeat carcasses passengers were carrying represent species whose continued existence is sufficiently threatened as to make it illegal to bring them into Europe.

Although the estimated amount of bushmeat imported from Africa to France is a tiny proportion of the total estimated kill (upward of 2.2 million tons per year in the Congo basin, say the ZSL scientists), “the volume and nature of import and trade suggests the emergence of a luxury market for African bushmeat in Europe,” they write in their paper. “Imports are supplying an organized system of trade and are not solely being brought for personal consumption. . . . The development of a luxury market, linked to increasing affluence of the consumer population, is of particular concern because of the potential for demand to remain high even as supply dwindles and prices rise, potentially driving the extinction of even relatively resilient species.”

And don’t look for it to stop any time soon. Detecting and seizing bushmeat, or other forms of vanishing species, is not a priority for customs officials, who find it time-consuming, unpleasant, and potentially dangerous. Unlike seizures of illegal drugs, intercepting the bodies of animals whose species is on the brink of extinction does not qualify for bonuses. To make matters worse, “most of the passengers carrying illegal meat were angry and outraged while the meat got confiscated,” Chaber (who is now the animal care supervisor at Al Ain Wildlife Park in theUnited Arab Emirates) told me by e-mail. “These bad reactions made customs uneasy about implementing fines as they felt confiscation was already a strong punishment for the guilty passengers.”

But even if European governments don’t care enough about vanishing species to change their airport policies, there might be one easy fix. One third of the passengers carrying bushmeat were flying on discounted Air France tickets, which go to family members of employees. If the airline imposed penalties, including the threat of dismissal, on the staff members through whom the tickets were obtained, that nice Nile croc might not seem like such a tempting carry-on in the future.

i LOVE optical illusions - check out this gallery with explanations as to why our brain perceives as it does. Below - these two tables have the same dimensions, really! - MA

Neuroscientists usually explain color illusions in mechanistic terms: They arise because of the way cells in the retina and the brain respond to certain wavelengths of light. Those explanations miss the larger point, says Beau Lotto, a brain research at University College London. We misperceive colors and shapes because our visual sense has been molded by evolutionary history.

Whale Poop Cleans the Environment
By JENNIFER VIEGAS
Whale waste is rich in iron so it stimulates the growth of phytoplankton, which then serve as carbon traps that remove some 400,000 estimated tons of carbon from the atmosphere each year.

THE GIST
  • New research shows that sperm whale waste stimulates carbon removal from the environment.
  • Since carbon has been linked to greenhouse gases, sperm whales likely reduce global warming.
  • Other marine mammals probably also help to remove carbon from the environment.
Sperm whale waste isn't much to look at -- a diarrhea-like substance with a few squid beaks floating around -- but new research has found it removes carbon from the atmosphere, helping to offset greenhouse gases that have been tied to global warming.

Sperm whales in the Southern Ocean release 220,462 tons of carbon when they exhale carbon dioxide at the water's surface, but their poo stimulates the drawdown of 440,925 tons of carbon, according to the research, published in the latest Proceedings of the Royal Society B.

These ocean giants and certain other marine mammals may therefore be among the most environmentally beneficial animals on the planet.

"If Southern Ocean sperm whales were at their historic levels, meaning their population size before whaling, we would have an extra 2 million tonnes (2,204,623 tons) of carbon being removed from our atmosphere each and every year," lead author Trisha Lavery Told Discovery News.

Lavery, a marine biologist at Flinders University of South Australia, and her colleagues explained how the cleaning process works.

It begins with sperm whales feeding on squid and fish, their favorite prey, deep in the ocean. The whales then return to the water's surface to relieve themselves.

"They do this because they shut down their non-crucial biological functions when they dive," Lavery said. "So it's only when they come to the surface to rest that they defecate."

Their waste comes out as a giant liquid plume (save for the undigested squid beaks) that showers over minute aquatic plant "seed stocks," which she said are "just floating around waiting for nutrients so they can use them to grow and reproduce." The whale poo provides these nutrients, functioning as a natural fertilizer.

The plants -- phytoplankton -- take up carbon from the ocean as they grow. Through the entire life and death cycle of these plants, the carbon then stays "trapped" for centuries to millennium.

Published estimates suggest that 12,000 sperm whales currently inhabit the Southern Ocean. Lavery and her team estimated the amount of prey consumed by each whale, along with the iron content of that prey. Iron is a critical phytoplankton fertilizer component.

Assuming that 75 percent of defecated iron persists in the photic -- or light receiving zone -- of the ocean, Southern Ocean sperm whales contribute 40 tons of iron to this region each year.

Humans driving cars, burning coal and engaging in other activities pump enormous amounts of carbon into the atmosphere, something that whales could never entirely offset.

"However, most whales are currently at 1 to 10 percent of their historical population sizes, so in the past, whales may have made a substantial contribution to carbon drawdown," Lavery said, adding that other marine mammals probably beneficially redistribute carbon just as whales do. These may include seals, sea lions and other types of whales, such as fin whales.

Unfortunately, some of these species wind up on sushi plates in restaurants here and abroad. A recent covert operation conducted by Scott Baker, associate director of Oregon State University's Marine Mammal Institute, determined that sashimi purchased at prominent sushi restaurants consisted of fin whale flesh, along with that of Antarctic minke whales, sei whales and a Risso's dolphin.

Lavery hopes all of the new research will help fuel efforts to conserve whales and other marine mammals.

"It is sometimes thought that conservationists try to 'save the whales' only because they are cute, however my work and the research of others is increasingly showing that whales play a crucial role in marine ecosystems," she said. "We must protect whales in order to have healthy, well-functioning marine ecosystems."

Abstract
The iron-limited Southern Ocean plays an important role in regulating atmospheric CO2 levels. Marine mammal respiration has been proposed to decrease the efficiency of the Southern Ocean biological pump by returning photosynthetically fixed carbon to the atmosphere. Here, we show that by consuming prey at depth and defecating iron-rich liquid faeces into the photic zone, sperm whales (Physeter macrocephalus) instead stimulate new primary production and carbon export to the deep ocean. We estimate that Southern Ocean sperm whales defecate 50 tonnes of iron into the photic zone each year. Molar ratios of Cexport ∶Feadded determined during natural ocean fertilization events are used to estimate the amount of carbon exported to the deep ocean in response to the iron defecated by sperm whales. We find that Southern Ocean sperm whales stimulate the export of 4 × 105 tonnes of carbon per year to the deep ocean and respire only 2 × 105 tonnes of carbon per year. By enhancing new primary production, the populations of 12 000 sperm whales in the Southern Ocean act as a carbon sink, removing 2 × 105 tonnes more carbon from the atmosphere than they add during respiration. The ability of the Southern Ocean to act as a carbon sink may have been diminished by large-scale removal of sperm whales during industrial whaling.

 

I had no idea a doe could kick so much ass! (read spoiler before watching)

This video probably requires an introductory spoiler, because the content will upset some viewers.

A fawn is discovered on a suburban street, where it is investigated (uneventfully) by a housecat. The doe arrives to guide the fawn away, but then sees a neighborhood dog, and her protective instincts kick into high gear: she ruthlessly pummels the dog with her front hooves. The cat eventually gets in a final slap and then beats a hasty retreat.

The deer’s attack on the dog will distress dog owners, but it serves as a reminder that from a deer’s point of view a dog is just a well-groomed coyote threatening her offspring.

(The person who posted the video left a followup comment that the dog appeared to recover from the beating.)

 

Clever critters: Bonobos that share, brainy bugs and social dogs

Dr. Brian Hare and Tassie doing some serious science

From Scientific American
By FERRIS JABR

When it comes to brain power, we humans like to think we're the animal kingdom's undisputed champions. But in the past few decades we've had to make a lot of room on our mantle place for shared trophies. Problem-solving? Sorry, but crows and octopuses do that too. Tool use? Primates, birds and even fish have learned that trick. It turns out our human cognitive abilities are just not as unique as we once thought.

The collapsing divisions between animal and human minds is exactly what a group of scientists gathered to discuss on Saturday, June 5, at a World Science Festival panel, "All Creatures Great and Smart." WNYC radio host Jad Abumrad mediated the talk.

The first topic of conversation was a behavior known as altruism: selflessly helping a stranger. Brian Hare, who studies ape psychology at Duke University, described a recent experiment on this kind of cooperation in bonobos—primates that are in the same genus as chimpanzees.

"We wanted to challenge that notion that humans are unique and test whether one of our closest relatives is capable of voluntarily sharing," Hare said. In the study, published earlier this year in Current Biology, researchers showed a bonobo into a room with some food inside. Instead of hogging all the grub, the bonobo consistently chose to unlock the door of an adjacent room and share the food with an unfamiliar bonobo.

The exact intentions behind this altruistic behavior remain unclear. Bonobos could expect a stranger to return the favor in the future, or "they could just be saying, 'You know what? I just want to go on a blind date,'" said Hare.

But "the smartest thing about bonobos is that they live in a society with very little violence," said Vanessa Woods, a science communicator and researcher at Duke, who is married to Hare. Woods explained how close-knit groups of females work together to keep the peace in bonobo societies, recounting an incident in which five unrelated female bonobos chased down a male bonobo who slapped another female for no reason. "One male can be stronger than one female, but no male is stronger than five females," Woods said.

"I try to stay good friends with all her girlfriends," Hare said of his wife, in a joking aside.

Altruism, sharing and cooperation aren't the only sophisticated behaviors animals demonstrate, the panelists explained. Klaus Zuberbühler, who studies the cognitive abilities of non-human primates, has found the rudiments of language in certain monkeys. Vervet and Diana monkeys, for example, have different alarm calls for different predators, reacting in the most appropriate way to signs of a leopard, eagle or snake. What recently astonished researchers is that monkeys aren't the only ones eavesdropping on each other—birds listen for the distinct calls as well.

Yellow-casqued hornbills—tropical birds that sport dusty orange mohawks—always perk up when Diana monkeys sound the eagle alarm, since eagles are a common enemy. But hornbills don't react to the Diana’s leopard alarm calls, because leopards usually can't catch the high-flying birds.

After so much talk about clever monkeys and apes, the panel switched their focus to a group of critters most people don't associate with intelligence: bugs.

"Insects can accomplish some very sophisticated things without big brains," said Jeremy Niven, an insect neuroscientist at the University of Cambridge. "It kind of makes you wonder why you need an extra billion neurons to be able to do something that a human does."

A slow-motion video of locusts traversing a horizontal ladder made of cocktail sticks played behind the panel. Niven explained how his recent studies show that locusts, despite their tiny brains, use their vision to control their swift leg movements with incredible precision, never missing a rung of the ladder even when the gaps between rungs are inconsistent between trial runs.

For a laugh, Niven also highlighted footage from an experiment designed to shed light on whether bees have aesthetic sensibilities. In the end, all the study showed is that bees prefer Van Gogh's Sunflowers to more classical flower portraits and to other colorful but flowerless paintings. "It's not really science," Niven said, chuckling, "but it's interesting nonetheless."

The panel discussion concluded with a dog show—a mini-parade of canine intelligence.

To set up the show, Hare explained that although many animals can think and make decisions, questions remain about whether animals can interpret the thoughts of others—an ability called "theory of mind" that humans develop by age three or four. One way to test this is to ask whether animals understand the same kinds of social cues human infants learn to recognize—like voice, gesture and gaze.

Sammy, a small white dog reminiscent of Toto from The Wizard of Oz, trotted on stage with his helper. Hare hid a piece of cheese in one of two tall bowls and pointed to the bowl containing the tempting morsel. Sammy immediately followed his direction.

"Are we sure Sammy isn't smelling the food?" Abumrad asked.

Hare tried the experiment again, but didn't point at any bowl this time. Sammy tried the wrong bowl and then wandered the stage. "When he doesn't have a social cue, he goes to the wrong place," Hare said. "We've found that dogs are incredibly good at this. They don't use olfactory cues—they would much prefer that you help them."

It's especially interesting that dogs are so good at taking social direction because chimpanzees, in contrast, rarely understand the same cues in the same kind of test. The chimps just don't get it.

In some ways, neither do we. As the panel demonstrated, animal minds are wrapped in many mysterious layers that we're only beginning to unravel.
