This is the wake-up call that we humans simply can’t afford to sleep through.
This stunningly beautiful image is of an Antarctic iceberg, with a cavity. It belies the power of ice to destroy the world that we currently experience, and that “we” is not just humans but vast tracts of nature and, of course, our dogs.
So what has got “my knickers in a twist“? Answer: A reminder that the potential melting of the Antarctic ice sheet is a real and tangible threat; something that mankind has understand within the next few years.
First, let me share some of the material from the website of Antarctic Glaciers.
An ice shelf is a floating extension of land ice. The Antarctic continent is surrounded by ice shelves. They cover >1.561 million km2 (an area the size of Greenland)[1], fringing 75% of Antarctica’s coastline, covering 11% of its total area and receiving 20% of its snow.
The difference between sea ice and ice shelves is that sea ice is free-floating; the sea freezes and unfreezes each year, whereas ice shelves are firmly attached to the land. Sea ice contains icebergs, thin sea ice and thicker multi-year sea ice (frozen sea water that has survived several summer melt seasons, getting thicker as more ice is added each winter).
You can see this flat, floating ice shelf is almost featureless.
With this in mind, let me turn now to a recent post from Patrice Ayme in which he spells out very clearly the metaphorical dagger hanging above all our heads.

Ice Sheets Melt: Academics Waking Up; New York Times In Denial
There has never been a more important moral, philosophical, military, civilizational, psychological, sociological and economic issue than the concerted holocaust of the biosphere by Homo Sapiens, presently passing one tipping point after another. Thus I will not present excuses for keeping abreast of any advance in understanding in the field. Even if it is just to confirm what I have long said.
The first scientific paper including computerized models of ice sheets melt predicts the obvious: if we burn all PROVEN fossil fuels reserves, ice will completely melt, all over Earth. Yet it is a big surprise to most scientists
“This is humanity as a geologic force,” said Ken Caldeira, a researcher at the Carnegie Institution for Science in Stanford, California, an author of the paper. “We’re not a subtle influence on the climate system – we are really hitting it with a hammer.”
Nice to read. Nietzsche was doing philosophy with a hammer, we went further: we are doing climate with a hammer. Hopefully, it will crack soon: nothing like a great catastrophe to bring further fascism. Nihilism is bad thing, naivety, even worse. To please the powers that be, and thus to be taken seriously, serious climate scientists have made unwarranted, profoundly unscientific, over-optimistic declarations about the ice sheets. Now their time is up. In truth the GreenHouse emissions are completely out of control, and still increasing… At a geological scale, every year:
50 Gigatons Per Year: This GreenHouse Is Bigger Than CO2 Alone.
“I didn’t expect it would go so fast,” Dr. Caldeira said. “To melt all of Antarctica, I thought it would take something like 10,000 years.” Didn’t they all. Why? Because only then would one be invited at the White House. Thinking correctly means, first, to think in a way that pleases those with power.
“Combustion of available fossil fuel resources sufficient to eliminate the Antarctic Ice Sheet” [Ricarda Winkelmann, Anders Levermann, Andy Ridgwell,, Ken Caldeira]:
“The Antarctic Ice Sheet stores water equivalent to 58 meters in global sea-level rise. We show in simulations using the Parallel Ice Sheet Model that burning the currently attainable fossil fuel resources is sufficient to eliminate the ice sheet. With cumulative fossil fuel emissions of 10,000 gigatonnes of carbon (GtC), Antarctica is projected to become almost ice-free with an average contribution to sea-level rise exceeding 3 m per century during the first millennium. Consistent with recent observations and simulations, the West Antarctic Ice Sheet becomes unstable with 600 to 800 GtC of additional carbon emissions. Beyond this additional carbon release, the destabilization of ice basins in both West and East Antarctica results in a threshold increase in global sea level. Unabated carbon emissions thus threaten the Antarctic Ice Sheet in its entirety with associated sea-level rise that far exceeds that of all other possible sources.”
The famous Doctor Hansen and his collaborators upset the establishment two months ago by predicting a rise of three meters within 85 years (they use the reasoning I have used before, namely that paleontological data show sea level rise of 5 to 9 meters, with a rise of just one degree Celsius; actually the reasoning was obvious since 2009, when I pointed out that “2C Is Too Much“). The new paper potentially confirms Hansen’s findings. As I said, the new paper tries to NOT upset the powers that be (differently from yours truly, who view most individuals and institutions in power more than suspiciously, and it shows). Thus, one has to read between the lines to deduce that, from the paper itself, interpreting it optimistically is completely unwarranted.
The paper says: “Consistent with recent observations and simulations, the West Antarctic Ice Sheet becomes unstable with 600 to 800 GtC of additional carbon emissions.” Hmm… Let’s see, how long would that take, at the present increasing rate? Now emissions of CO2 itself are around 35 Gt, per year. That’s a number often brandished, but, left at that, it’s disinformation. With other GreenHouse Gases, we are at 50 Gigatons of CO2 equivalent emission, per year. Sorry for taxing the mathematical capabilities of our great leaders: 12 x 50 = 600. This fits perfectly my “Ten Years To Catastrophe” essay. Thus, the West and EAST Antarctic Ice Sheet becomes unstable in TWELVE YEARS (according to this paper; I obtained the same rough estimate with a paleoclimate approach).
The United Nations has said that the rise of the sea would not likely exceed three feet in this century. Some island nations will be wiped out (oops). Yet experts officially hope that major cities could be protected from it, in the richest countries that is (re-oops), though at a cost in the trillions of dollars (contemplate the enormous works to protect London or Venice).
The New York Times mentioned the paper above, which say the ice sheets will start melting irreversibly within a decade, to argue, in Politically Correct fashion, that ice sheets respond slowly enough to changes in the climate that it simply takes longer than a century for large-scale melting to begin. As if that notion was in the paper. It is not. Far from it. As I have argued before, that notion is ridiculous.
Subglacial Basins Are The Achilles’ Heel Of The Biosphere.
{WAIS = West Antarctica Ice Shelf; WB = Wilkes Basin; AB = Aurora Basin.]
Yet from that (tipping) point on, the paper found that thereafter, the sea would rise at the rate at a foot per decade, ten times faster than now, the New York Times admitted.
However the real text is much more alarming. Here is an extract:
“The Antarctic Ice Sheet is severely affected by high carbon emissions through both the marine ice-sheet instability and surface elevation feedbacks. On the time scale of millennia, large parts of the ice sheet melt or drain into the ocean, raising global sea level by several tens of meters. Most of the ice loss occurs within the first millennium, leading to high rates of sea-level rise during this period (Fig. 3; for more details, see also fig. S6). Our simulations show that cumulative emissions of 500 GtC commit us to long-term sea-level rise from Antarctica of 1.15 m within the next millenium, which is consistent with the sensitivity of 1.2 m/°C derived with a different ice-sheet model (33, 34). Paleo data suggest that similar rates of sea-level rise have occurred during past warm periods (35). If the 2°C target, corresponding to about 600 GtC of additional carbon release compared to year 2010, were attained, the millennial sea-level rise from Antarctica could likely be restricted to 2 m. In our simulations, this would keep the ice sheet below the threshold for the collapse of the Wilkes Basin. However, if that threshold is crossed, the Antarctic ice cover is significantly reduced in thickness and area (Fig. 4). If we were to release all currently attainable fossil fuel resources, Antarctica would become almost ice-free. It is unclear whether this dynamic discharge would be reversible and, if so, on which time scales.”
As I already said, since 2010, we have added another 230 Gigatons. So we are within eight year of the Wilkes ice sheet, the largest in the world, to become unstable. The paper admitted that about half the Antarctic ice sheet would melt or fall into the sea in the first thousand years.”
The New York Times’ interpretation that it will take nearly a century for dramatic melting to start was obviously tainted. It is just driven by political Machiavellianism: let’s admit there is climate “change” just as there is sea level “change”, and misinform about the unfolding catastrophe (although Main Stream Media had to recently admit the snow pack in California last April was the lowest in at least 500 years). How do I know this? The scientific paper used computerized models of the huge ice sheets covering Antarctica and Greenland. It is the first paper to do so. Yet, according to the biased New York Times, it would have found exactly what the UN found, during this century… Although the UN did not incorporate the ice sheet melt models.
Once the ice sheet melting is incorporated, faster melting ought to have been predicted, for THIS century. However that grim prediction would have upset the powers that be. We don’t want that to happen. Now that they have the drone habit, killing throngs of people they know nothing about, who knows what’s coming next if one disparages them? Beheading and crucifixion at the most esteemed Saudi plutocracy?
For plutocrats, the Saudis are a model of Human Rights: thus they elected them to head the UN panel on Human Rights. And ice sheet melting is perfect: all great catastrophes call onto what Obama calls “leaders” (our masters). If a bit of engineered inflation could bring Hitler, imagine what an inflating ocean can bring! A great future for the few who rule us, tax free.

Let me close with two pictures:
That is a very great deal of water locked up in that ice!
and this one that shows how at least one would have a wonderful view of the sea from your room at the Boston Harbour Hotel!
Fundamentally, today’s post is not about dogs. But it is about the qualities that we can see in our dogs: trust, honesty, openness, and the core quality that inspires my writings about dogs: integrity.
I’m speaking of the disgusting news that has been headlined in the world’s media in recent days, no better summarised than by this extract from a current (1pm PDT yesterday)) BBC news report:
Volkswagen chief executive Martin Winterkorn has resigned following the revelation that the firm manipulated US diesel car emissions tests.
Mr Winterkorn said he was “shocked” by recent events and that the firm needed a “fresh start”.
He added that he was “not aware of any wrongdoing on my part” but was acting in the interest of the company.
VW has already said that it is setting aside €6.5bn (£4.7bn) to cover the costs of the scandal.
The world’s biggest carmaker admitted last week that it deceived US regulators in exhaust emissions tests by installing a device to give more positive results.
The company said later that it affected 11 million vehicles worldwide.
As ever, the voice of George Monbiot speaks a little clearer than most, and I am referring to his recent essay published both on his blog and in The Guardian newspaper. I am very pleased to have Monbiot’s permission to republish his essay here on Learning from Dogs.

Smoke and Mirrors
22nd September 2015
Pollution, as scandals on both sides of the Atlantic show, is a physical manifestation of corruption.
By George Monbiot, published in the Guardian 23 September 2015
In London, the latest figures suggest, it now kills more people than smoking. Worldwide, a new study estimates, it causes more deaths than malaria and HIV-Aids together. I’m talking about the neglected health crisis of this age, that we seldom discuss or even acknowledge. Air pollution.
Heart attacks, strokes, asthma, lung and bladder cancers, low birth weight, low verbal IQ, poor memory and attention among children, faster cognitive decline in older people and – recent studies suggest – a link with the earlier onset of dementia: all these are among the impacts of a problem that, many still believe, we solved decades ago. The smokestacks may have moved to China, but other sources, whose fumes are less visible, have taken their place. Among the worst are diesel engines, sold, even today, as the eco-friendly option, on the grounds that their greenhouse gas emissions tend to be lower than those of petrol engines. You begin to wonder whether any such claims can still be trusted.
Volkswagen’s rigging of its pollution tests is an assault on our lungs, our hearts, our brains. It is a classic example of externalisation: the dumping of costs that businesses should carry onto other people. The air that should have been filtered by its engines is filtered by our lungs instead. We have become the scrubbing devices it failed to install.
Who knows how many people have paid for this crime already, with their health or with their lives? In the USA, 200,000 deaths a year are attributed to air pollution. For how many of those might Volkswagen be responsible? Where else was the fraud perpetrated? Of what proportion of our health budgets has this company robbed us?
The fraud involves the detection of nitrogen oxides (NOx), of which diesel engines are the major source in many places. This month, for the first time in our history, the UK government estimated the impact of NOx emissions on public health, and discovered that they are likely almost to double the number of deaths from air pollution, adding 23,000 to the 29,000 attributed to particulates (tiny particles of soot).
The government released this discovery, alongside its useless proposals for dealing with the problem, on Saturday 12 September, a few minutes before Jeremy Corbyn’s election as Labour leader was announced. How many government press releases are published on a Saturday? How many are published on a Saturday during an event on which everyone is focused? In other words, as a Labour press officer once notoriously advised, this was “a good day to bury bad news”. Not only was the number of deaths buried by this means, but so was the government’s consultation on its feeble plans for reducing this pollution: a consultation to which it evidently wanted as few respondents as possible. Liz Truss, the environment secretary, has some explaining to do.
She has her reasons for keeping us in the dark. In April, the Supreme Court ruled that the UK is in breach of the European air quality directive, and insisted that the government draw up a plan for compliance by the end of this year. Instead, Truss produced a plan to shed responsibility. Local authorities, her consultation suggests, should create clean air zones in at least eight cities, in which diesel engines are restricted or banned. But she has given them neither new money nor new powers. Nor has she offered an explanation of how this non-plan is going to address the issue in the rest of the country, as the ruling demands.
Already, the UK has missed the European deadline by six years. Under Truss’s proposals, some places are likely still to be in breach by 2025: 16 years after the original deadline. I urge you to respond to the consultation she wanted you to miss, which closes on November 6.
The only concrete plan the government has produced so far is to intensify the problem, through a new programme of airport expansion. This means more nitrous oxides, more particulates, more greenhouse gas emissions.
Paradoxically, the Volkswagen scandal may succeed where all else has failed, by obliging the government to take the only action that will make a difference: legislating for a great reduction in the use of diesel engines. By the time this article is published, we might know whether the company’s scam has been perpetrated in Europe as well as North America: new revelations are dripping by the hour. But whether or not this particular deception was deployed here, plenty of others have been.
Last week the Guardian reported that nine out of ten new diesel cars break European limits on nitrous oxides – not by a little but by an average of sevenfold. Every manufacturer whose emissions were tested had cars in breach of the legal limit. They used a number of tricks to hotwire the tests: “stripping components from the car to reduce weight, using special lubricants, over-inflating tyres and using super-smooth test tracks.” In other words, the emissions scandal is not confined to Volkswagen, not confined to a single algorithm and not confined to North America: it looks, in all its clever variants, like a compound global swindle.
There are echoes here of the ploys used by the tobacco industry: grand deceptions smuggled past the public with the help of sophisticated marketing. Volkswagen sites advertising the virtues of “clean diesel” have been dropping offline all day. In 2009, the year in which its scam began, the TDI engine at the centre of the scandal won the Volkswagen Jetta 2.0 the green car of the year award. In 2010, it did the same for the Audi A3.
There’s plenty that’s wrong with corporate regulation in the United States, but at least the fines, when they occur, are big enough to make a corporation pause, and there’s a possibility of guilty executives ending up in prison. Here, where corruption, like pollution, is both omnipresent and invisible, major corporations can commit almost any white-collar crime and get away with it. Schemes of the kind that have scandalised America are, in this country, both commonplace and unremarked. How can such governments be trusted to defend our health?
I found myself having two emotional reactions to Monbiot’s essay. The first was that for many years, when I was living and working in England, I drove diesel-powered cars on the (now false) belief that they were better for the environment.
My second reaction was to Monbiot listing the likely impacts from air pollution,”Heart attacks, strokes, asthma, lung and bladder cancers, low birth weight, low verbal IQ, poor memory and attention among children, faster cognitive decline in older people and – recent studies suggest – a link with the earlier onset of dementia. . . “, for the reason that at the age of 70, I am already noticing the creeping onset of reduced verbal IQ, cognitive decline, and worry about the onset of dementia. To think that my earlier decisions about what cars to drive might be a factor in this is disturbing.
I am going to close this post by highlighting how fighting for what we want is important, critically so. By republishing an item that was posted on AmericaBlog just over a year ago, that fortuitously is a reward for living in the State of Oregon.

Climate win: Appeals court in Oregon rules state court must decide if atmosphere is a “public trust”
6/16/14 10:00am by Gaius Publius
Two teenagers from Eugene, Ore. filed suit against Governor Kitzhaber and the State of Oregon for failing to protect the “atmosphere, state waters, and coast lines, as required under the public trust doctrine.”
They lost the first round, where the state court said that climate relief was not a judicial matter. But they won on appeal. The case goes back to the original court, which now has orders to decide the case on its merits and not defer to the executive or legislature.
The gist of the appeals court decision:
Their lawsuit asked the State to take action in restoring the atmosphere to 350 ppm of CO2 by the end of the century. The Oregon Court of Appeals rejected the defenses raised by the State, finding that the youth could obtain meaningful judicial relief in this case.
That’s quite a nice victory. Here’s the full story, from the Western Environmental Law Center (my emphasis throughout):
In a nationally significant decision in the case Chernaik v. Kitzhaber, the Oregon Court of Appeals ruled a trial court must decide whether the atmosphere is a public trust resource that the state of Oregon, as a trustee, has a duty to protect. Two youth plaintiffs were initially told they could not bring the case by the Lane County Circuit Court. The trial court had ruled that climate change should be left only to the legislative and executive branches. Today, the Oregon Court of Appeals overturned that decision.
Two teenagers from Eugene, Kelsey Juliana and Olivia Chernaik, filed the climate change lawsuit against Governor Kitzhaber and the State of Oregon for failing to protect essential natural resources, including the atmosphere, state waters, and coast lines, as required under the public trust doctrine. Their lawsuit asked the State to take action in restoring the atmosphere to 350 ppm of CO2 by the end of the century. The Oregon Court of Appeals rejected the defenses raised by the State, finding that the youth could obtain meaningful judicial relief in this case. …
In reversing the Lane County trial court, the Oregon Court of Appeals remanded the case ordering the trial court to make the judicial declaration it previously refused to make as to whether the State, as trustee, has a fiduciary obligation to protect the youth from the impacts of climate change, and if so, what the State must do to protect the atmosphere and other public trust resources.
The implications of this are broad, and similar cases are pending in other states, as the article describes.
Make no mistake; decisions like this matter. It places the court squarely in the mix as a power player in the climate war, the fight for “intergenerational justice” as James Hansen puts it — or the war against intergenerational betrayal, as I put it.
This is a cornerstone decision from the Oregon Court of Appeals in climate change jurisprudence. The court definitively ruled that the question of whether government has an obligation to protect the atmosphere from degradation leading to climate change is a question for the judiciary, and not for the legislative or executive branches. The Court did not opine as to how that question should be answered, only that it should be answered by the judiciary.
We can win this; it’s not over. If we reach 450 ppm and we’re still not stopping with the CO2, then it’s over and I become a novelist full-time. But we’re not there yet, and please don’t surrender as if we were.
The courts are now a powerful tool, as is divestment. James Hansen has a way to restore the atmosphere to 350 ppm CO2 in time to stop slow feedbacks from kicking in. It’s a doable plan, but we’ll need to use force. Using the courts, as with using divestment campaigns, counts as force. Stay tuned.
(Want to use force at the national level? Find a way to challenge Obama publicly to stop leasing federal land to coal companies. He’s a hypocrite until he stops federal coal from being mined and sold abroad. A simple and obvious challenge for him. You too can be the activist.)

We can never be reminded too often of this most special bond.
Again, the pressures of the book and the fact that Jean and I were away from the house until early afternoon, made it difficult for me to spend time writing a post from scratch.
Then in my blog folder, I saw this lovely story reported by the British Daily Mail newspaper; to be honest, probably quite some time ago.

Touching moment as firefighters save this dog from flood waters.
Two firefighters with the Austin Fire Department were pictured saving a dog from flood waters in central Texas yesterday.
The department posted the picture of firefighters Matt Harvey and Michael Cooper with the animal to their Facebook page, saying: ‘We don’t just rescue two-legged victims…we love our four-legged friends as well.”
The animal looks like it’s been through a lot, and clings to one of the firefighters as if they’re hugging.
There was a bonus in waiting a while before publishing this. For the story of the dog being reunited with its owner made television news.
You may recall that back on the 15th of this month, I posted a Note to Readers that spoke about my need to be focused on the editing of my manuscript. Here’s part of that note:
Dear readers, we are talking hours of revisions that I need, and want, to make.
All of which is my way of saying that if my posts over the next couple of weeks more strongly lean on the republishing of other material then you will understand why. In all cases I will endeavour to republish articles that are likely to interest you, of course!
Late yesterday, I completed the many revisions to the manuscript recommended by Joni Wilson but still have more days of formatting changes ahead.
Thus another republication of an item, this time an article that appeared on the Smithsonian website.

Domestication Seems to Have Made Dogs a Bit Dim
Thanks to their relationship with us, dogs are less adept at solving tricky puzzles than their wolf relatives
It’s OK, buddy. We’re here to help. (stelo/iStock)
By Rachel Nuwer, smithsonian.com, September 15, 2015
Dogs are considered some of the most intelligent animals on the planet. Thanks to a relationship with humans that dates back tens of thousands of years, dogs can respond to emotions, recognize numerous words and be trained to follow commands.
Notably, these seemingly smart accomplishments all hinge on the partnership between our two species. Now, however, tests of canine problem-solving skills indicate that dogs rely on humans so much that we actually seem to be dumbing them down.
Most studies that investigate dog intelligence assume that certain interactions with humans are indicative of higher cognitive function. In one experiment, for example, dogs and human-socialized wolves were presented with a canine version of the Kobayashi Maru — an unopenable box that contained food.
When confronted with a difficult task, dogs often turn to us—their human masters—for guidance, indicating their puzzlement with a cock of the head and eyes that seem to implore for help. Indeed, the dogs in the study quickly gave up and simply stared at the nearest human. The wolves, on the other hand, sought out no such help and persisted at trying to solve the impossible puzzle on their own.
Researchers usually interpret such findings as a sign of dogs’ intelligence; the wolves kept trying to win the no-win scenario, while the dogs knew that humans could help out with tasks they themselves could not solve.
But depending on humans for help is not necessarily a cognitive asset, points out Monique Udell, an assistant professor of animal and rangeland sciences at Oregon State University.
If dogs only turn to humans when presented with an impossible task—not a solvable one—then their “look back” behavior would indeed be advantageous. On the other hand, if they simply throw their paws up at the slightest hint of cognitive challenge, then that could indicate “a conditioned inhibition of problem-solving behavior,” as Udell puts it. Like a child whose parents always give away the answers to homework, dogs may be overly reliant on us, she surmised.
To test this hypothesis, Udell presented ten pet dogs and ten human-socialized wolves with a solvable puzzle. Sausage was placed inside a sealed plastic tub with a lid that included a bit of rope. With some paw and mouth finagling, the lid could be opened.
She also included ten shelter dogs in the study, because past research shows that shelter dogs are initially less responsive to humans compared to established pets. These animals acted as a sort of intermediary between hyper-socialized dogs and wolves.
Crazy smart, like a wolf. (Kaphoto/iStock)
Udell presented the canines with the puzzle box both in the presence of humans—an owner, caretaker or familiar person—and without any person nearby. Each time, the animals had two minutes to figure out how to get at the sausage. Subjects that failed in both trials were given a third and final try in which they also received verbal encouragement from their human friend.
Udell’s findings, reported today in the journalBiology Letters, were telling. In the presence of humans, just one pet dog and none of the shelter dogs managed to open the box. Eight out of ten of the wolves, however, succeeded in enjoying the sausage treat inside.
Wolves also spent more time chipping away at the problem and more time staring at the box, as if working out how to open it. Both pet and shelter dogs, on the other hand, did the opposite—they gave up more quickly and stared at humans instead of the box, seemingly asking for help.
When humans were not around, the findings were similar—nearly all of the wolves figured out how to open the box, while just one shelter dog and no pet dogs succeeded. In the third and final trial, dogs that had failed in both of the prior tests performed a bit better when humans encouraged them.
With some human cheerleading, four of nine shelter animals and one of eight pet dogs opened the box, and all spent more time trying to open the box and looking at the box than they did when they were either alone or when their human friends remained silent.
Udell’s results indicate that dogs do seem to be overly dependent on us compared to their wild relatives, although the cause of this—whether biological, environmental or both—still needs to be worked out.
Lucky for pet pooches, however, we humans will no doubt always be there to help them navigate all of life’s tricky plastic containers.
Picking up on that last sentence, luckily for us humans our dogs will always be there to help us in innumerable ways, especially giving us unconditional love.
Chris Snuggs, friend from my English days, linked to an item on his Facebook page about the appalling loss of elephants and rhinos. The item included this picture:
The reason I am writing about this today is to give readers notice that on Saturday, October 3 from 10:30am – 3:00pm there is a march, a global march, for Elephants and Rhinos. The item on Facebook details the location as Jefferson Square, 1101 Eddy St, San Francisco, California 94109.
If we lived closer to San Francisco we would most definitely attend.
Back to Chris’ Facebook entry where he subsequently wrote:
I am flattered! I thought it was just my usual bilious rant! Actually, the killing of rhinos, tigers, elephants and so on is so surreally-pointless and evil as to be almost beyond belief. You might like this photo of a rhino I saw in Senegal from about 20 metres away! Magnificent and totally innocent creatures, unlike Homo Sapiens I fear.
Jean and I feel the same way about the hunting of any animals for any purpose other than feeding oneself.
The wonderful way that animals have evolved to survive life on the go.
It is very easy to look at our wonderful domesticated dogs and forget that genetically they are still very much hunting dogs. Of all the dogs that we have had Dhalia seemed the most closely connected with those instincts, and she is still missed more than a year after she died. So much so that I’m going to republish part of the post that commemorated her life just after she died. Here it is:
Dhalia, as with so many other dogs, offered lasting lessons. April 8th, 2014
Inevitably, as Jean and I went around our ‘stuff’ yesterday after burying Dhalia in the morning, there were moments of quiet contemplation and gentle discussion. Interludes over a hot drink where we reflected on the special dog that she was.
Much has already been written in this place but there can’t be too many reminders for us quirky humans of how valuable are the qualities of trust and love given to us by our dogs.
We need reminding how dogs are so intuitive and can reach out to a stranger without a moment of hesitation. As Jean described when recalling how she first came across Dhalia.
Dhalia – domesticated but still the wild dog shows through.
It was a Sunday around the middle of the month of September in the year 2005. My friend, Gwen, and I had set off for La Manga, a small fishing village three miles from San Carlos, Mexico. As the trip would take us through areas of desolate desert and the day was forecast to be a sizzler, we left early. The purpose of the journey was to feed a pack of dogs that were living on the outskirts of La Manga. These wild dogs were gradually getting used to our presence and with the aid of a humane trap we had previously caught two of them, a small puppy and her mother. Those two dogs were at my home and were gradually becoming tame so that good homes could be found for them.
Half-way to our destination, we saw two dogs running by the side of the road. It wasn’t unusual to see strays searching for road-kill. I stopped the car and prepared food and water for them. One dog took off almost immediately but the other just stood perfectly still looking intently at me. She was rail-thin and full of mange. Her ears and chest were scabbed with blood, and I could see that previously she had had pups. Tentatively, I pushed the food towards her. She took a bite and sat on her haunches; her eyes never leaving mine. Then she lifted a paw and reached out to me. Immediately, I burst into tears and scooped her into my arms. I carried her back to the car where she lay quietly in my lap whilst we went on to do our feeding. She was bloody and very smelly. However, I didn’t care.
Dhalia was always a gentle dog. One that would mix with any of the other dogs. A dog that loved people, of all types and ages.

Motion dazzle: spotting the patterns that help animals outsmart predators on the run
Zebra are seen running at the Serengeti National Park in Tanzania Nov. 14, 2013. (U.S. Navy photo by Mass Communication Specialist 1st Class Eric Dietrich/Released)
Many animals use the colours and patterns on their bodies to help them blend into the background and avoid the attention of predators. But this strategy, crypsis, is far from perfect. As soon as the animal moves, the camouflage is broken, and it is much easier for a predator to see and catch it. So how do animals protect themselves when they’re on the move?
Researchers are exploring whether high-contrast patterns during motion, such as stripes and zigzags, may be distorting the predator’s perception of where the animal is going. But, as little is known about such “motion dazzle”, we have built an online game to help shed light on it.
Lessons from war
The idea is that it may be more effective for animals to focus on preventing capture, rather then preventing detection or recognition, is actually more than 100 years old. It was naturalist Abbott Thayer who suggested that high-contrast patterns may distort the perceived speed or direction of a moving object, making it harder to track and capture.
Such motion dazzle patterns were actually used in World War I and II, where some ships were painted with black and white geometric patterns in an attempt to reduce the number of successful torpedo attacks from submarines. However, due to many other factors affecting wartime naval losses, it is unclear whether motion dazzle patterns actually had the desired effect.

What about the natural world? Zebras have bold stripes, and scientists have debated the function of their patterns since Darwin’s time. A recent modelling study suggested that when zebras move, their stripes create contradictory signals about their direction of movement that is likely to confuse predators. There are potentially two visual illusions responsible for this, which could form the basis of motion dazzle effects: the wagon wheel effect and the barber pole illusion.
The wagon wheel effect is named after Western movies, where the wheels on wagons often appear to be moving backwards. This is because the visual system takes “snapshots” over time and links them to create a continuous scene, in the same manner as recording film. If a wheel spoke moves forward rapidly between sampling events, it will appear to have moved backwards as it will be misidentified as the following spoke.
The barber pole illusion (also known as the aperture effect) occurs because the moving stripes provide ambiguous information about the true direction of movement. These illusory effects produced by stripes could therefore lead to difficulties in judging the speed and movement of a moving target. However, the zebra study was entirely theoretical and didn’t test whether striped patterns actually affected the judgements of real observers.
Dazzle Bug
Surprisingly, the first experimental tests of the effectiveness of motion dazzle patterns weren’t carried out until recently. Some studies have shown that strikingly patterned targets can be more difficult to catch than targets with other patterns in studies using humans as “predators” playing touch screen computer games. However, other studies have found no clear advantage for motion dazzle patterns So although patterns can affect our perception of movement, it’s still not clear which are most effective at doing so.

We are addressing the question of which patterns are best for avoiding predators during movement using Dazzle Bug – an online game that asks players to imagine themselves as a predator, trying to catch a moving bug as fast as possible. Each bug has a different body pattern as well as a random pattern of movement. Bugs with easy to catch patterns will disappear, whereas those that are particularly tricky to catch will survive ––just like in nature. Over time, the patterns on the bugs’ body will evolve so that they become harder to catch with each successive generation.
This citizen science project will allow us to see what patterns are most effective at evading capture. We can then use these results to look at what visual effects these patterns have, and to see whether these patterns match up with those found on real animals in the wild.
Our findings will offer insight into the role of stripes, which are common in many species. While these patterns may have evolved to confuse the visual perception of a predator, they may also be a result of other selection pressures, such as attracting a mate or regulating body temperature. If striped patterns survive and evolve in the game, this would provide strong evidence that these patterns do act to confuse human predators, perhaps by producing the illusions described above. As motion perception seems to be highly conserved across a wide range of populations, these illusions may occur for many other predators too.
If we find that patterns other than stripes – such as speckles, splotches or zigzags – are most effective in preventing capture, this then leads to new and interesting questions about how these patterns may act to confuse or mislead. Whatever the outcome, Dazzle Bug will provide insight into how bodily patterns may have evolved to help animals to survive life on the go.
A very interesting report that recently appeared on Mother Nature Network (MNN).
We live in Josephine County here in Southern Oregon. Our next door neighbours to the East are Jackson County. Josephine and Jackson Counties share one very noble attribute: each is only one of just nine GMO-free counties in the entire United States of America. Plus, as evidenced at our local Grants Pass Farmers’ Market every Saturday, the growing of organic fruit and vegetables is widespread in our county. We feel very happy to have ended up in this part of America.
All of which makes a logical introduction to a report that appeared on MNN on September, 1st. It is republished below.

For safer, cheaper pest control, just add ants
Ants offer a surprisingly effective alternative to synthetic pesticides on crops ranging from cashews to sugar cane, according to a new review of more than 70 scientific studies.

Sometimes ants are pests, marching through our kitchens on an industrious quest for crumbs. But when faced with more serious pests — namely those that destroy crops on which people’s livelihoods depend — we can also use ants to our advantage.
Published in the Journal of Applied Ecology, a new research review suggests ants can control agricultural pests as efficiently as synthetic pesticides, with the bonus of being more cost-effective and generally safer. And since many pesticides pose a danger to helpful wildlife like birds, bees and spiders — not to mention humans — ants might be a key ally in feeding the planet’s booming human population.
The review covers more than 70 scientific studies on dozens of pest species that plague nine crop varieties in Africa, Southeast Asia and Australia. Because ants are organized as “superorganisms” — meaning the colony itself is like an organism, with individual ants acting as “cells” that can move around independently — they are uniquely capable of hunting down pests and then overwhelming them.
“Ants are great hunters and they work cooperatively,” says author Joachim Offenberg, a biologist at Aarhus University in Denmark, in a press release about the research. “When an ant finds its prey, it uses pheromones to summon help from other ants in the nest. By working together, they can subdue even large pests.”
Most studies in the review focused on weaver ants, a tropical genus of tree-dwelling ants that weave ball-shaped nests using leaves and larval silk. Since they live in the canopy of their host trees, near the fruit and flowers that need protection, weaver ants have a natural tendency to control pest populations in orchards.

In one three-year study, Australian cashew growers recorded yields 49 percent higher in trees guarded by weaver ants versus trees treated with synthetic chemicals. But higher yields were only part of the prize: The farmers also got higher-quality cashews from the trees with ants, resulting in a 71 percent higher net income.
Similar results were reported in mango orchards. While mango trees with ants had roughly the same yields as those with synthetic chemicals, the ants were cheaper — and the trees they inhabited grew higher-quality fruit. That led to a 73 percent higher net income compared with pesticide-treated trees. Not all crops had such dramatic results, but studies on more than 50 pests showed that ants can protect crops including cocoa, citrus and palm oil at least as effectively as pesticides.
“Although these are rare cases where the ants were superior to chemicals, many studies show that ants are just as efficient as chemical controls,” Offenberg says. “And of course ant technology is much cheaper than chemical pest control.”
To recruit weaver ants in their orchards, farmers just collect nests from the wild, hang them in plastic bags from tree branches and feed them a sugar solution while they build new nests. Once the ants establish their colony, farmers can help them expand by connecting target trees with aerial walkways made from string or vines.
The ants are mostly self-sufficient from there, needing only some water during the dry season — provided via plastic bottles in the trees — and pruning of non-target trees that host different ant colonies to prevent fights. Farmers can also help their ants by avoiding broad-spectrum insecticide sprays, researchers say.

It’s worth noting that ants can also be detrimental to some plants, such as when they herd sap-feeding insects like aphids and leafhoppers. But if they still fend off fruit-ruining flies and beetles, their net impact may be positive nonetheless. Not only do weaver ants kill pest insects on their trees, but their presence alone is reportedly enough to scare away marauders as large as snakes and fruit bats. And research suggests their urine even contains important plant nutrients.
The use of ants for pest control isn’t new. As early as 300 B.C., Chinese farmers could buy weaver ants in markets to release in their citrus groves, a practice that has faded over time, especially after the advent of chemical pesticides. But it may be coming back, both because ants are cheaper than pesticides and because certified organic produce can fetch higher prices, due to concerns that broad-spectrum pesticides harm more than just pests. Aarhus University is studying the use of weaver ants as pest control in Benin and Tanzania, for example, where the insects could lead to increased export revenue of $120 million and $65 million, respectively.
“To kill the flies with pesticides, you have to make the mango so poisonous that it can kill the maggot,” Aarhus University biologist Mogens Gissel Nielsen told China’s Xinhua news agency in 2010. “But when it is too poisoned for the maggot to eat, it might not be good for us to eat either.”
While the research in Offenberg’s review focused largely on weaver ants, he points out they “share beneficial traits with almost 13,000 other ant species, and are unlikely to be unique in their properties as control agents.” Lots of ants nest in the ground, and while it may be a challenge to relocate them, they too have shown promise in protecting a variety of commercially important crops.
“Weaver ants need a canopy for their nests, so they are limited to plantations and forestry in the tropics,” Offenberg says. “But ground-living ants can be used in crops such as maize and sugar cane. European wood ants are renowned for controlling pests in forestry, and new projects are trying to use wood ants to control winter moths in apple orchards. Ants could even be used to fight plant pathogens because they produce antibiotics to combat diseases in their dense societies.”
