That Look – Of A Siberian Husky!

Those eyes!

Of all the dogs that we can look at the Siberian Husky takes the biscuit! I’m talking about those eyes!

Up until reading this article in the Smithsonian I hadn’t really stopped to wonder how those eyes came about.

How Siberian Huskies Get Their Piercing Blue Eyes

A new study suggests that the defining trait is linked to a unique genetic mutation

At-home DNA kits have become a popular way to learn more about one’s ancestry and genetic makeup—and the handy tests aren’t just for humans, either. Dog owners who want to delve into their fluffy friends’ family history and uncover the risks of possible diseases can choose from a number of services that screen doggie DNA.

As Kitson Jazynka reports for National Geographic, one of these services, Embark Veterinary, Inc., recently analyzed user data to unlock an enduring canine mystery: How did Siberian huskies get their brilliant blue eyes?

Piercing peepers are a defining trait of this beautiful doggo. According to the new study, published in PLOS Genetics, breeders report that blue eyes are a common and dominant trait among Siberian huskies, but appear to be rare and recessive in other breeds, like Pembroke Welsh corgis, old English sheepdogs and border collies. In some breeds, like Australian shepherds, blue eyes have been linked to patchy coat patterns known as “merle” and “piebald,” which are caused by certain genetic mutations. But it was not clear why other dogs—chief among them the Siberian husky—frequently wind up with blue eyes.

Hoping to crack this genetic conundrum, researchers at Embark studied the DNA of more than 6,000 pooches, whose owners had taken their dogs’ saliva samples and submitted them to the company for testing. The owners also took part in an online survey and uploaded photos of their dogs. According to the study authors, their research marked “the first consumer genomics study ever conducted in a non-human model and the largest canine genome-wide association study to date.”

The expansive analysis revealed that blue eyes in Siberian huskies appear to be associated with a duplication on what is known as canine chromosome 18, which is located near a gene called ALX4. This gene plays an important role in mammalian eye development, leading the researchers to suspect that the duplication “may alter expression of ALX4, which may lead to repression of genes involved in eye pigmentation,” Aaron Sams of Embark tells Inverse’s Sarah Sloat.

The genetic variation was also linked to blue eyes in non-merle Australian shepherds. Just one copy of the mutated sequence was enough to give dogs either two blue eyes, or one blue and one brown eye, a phenomenon known as “heterochromia.” It would seem, however, that duplication on chromosome 18 is not the only factor influencing blue eye color: Some dogs that had the mutation did not have blue eyes.

More research into this topic is needed to understand the genetic mechanisms at work when it comes to blue-eyed dogs. But the study shows how at-home DNA kits can be highly valuable to scientists, providing them with a wealth of genetic samples to study.

“With 6,000 people getting DNA samples from their dogs and mailing them to a centralized location and then filling out a website form detailing all the traits of their dog—that’s a game-changer for how genetics is being done in the 21st century,” Kristopher Irizarry, a geneticist with the College of Veterinary Medicine at Western University of Health Sciences, tells National Geographic’s Jazynka.

The benefits of having access to such huge troves of data go further than uncovering nifty insights into our canine companions. Scientists are also teaming up with at-home DNA test companies to learn more about human genetics and behavior.

Why the number 137 is one of the greatest mysteries in physics

Famous physicists like Richard Feynman think 137 holds the answers to the Universe.

By PAUL RATNER,  31st October, 2018.

  • The fine structure constant has mystified scientists since the 1800s.
  • The number 1/137 might hold the clues to the Grand Unified Theory.
  • Relativity, electromagnetism and quantum mechanics are unified by the number.

Does the Universe around us have a fundamental structure that can be glimpsed through special numbers?

The brilliant physicist Richard Feynman (1918-1988) famously thought so, saying there is a number that all theoretical physicists of worth should “worry about”. He called it “one of the greatest damn mysteries of physics: a magic number that comes to us with no understanding by man”.

That magic number, called the fine structure constant, is a fundamental constant, with a value which nearly equals 1/137. Or 1/137.03599913, to be precise. It is denoted by the Greek letter alpha – α.

What’s special about alpha is that it’s regarded as the best example of a pure number, one that doesn’t need units. It actually combines three of nature’s fundamental constants – the speed of light, the electric charge carried by one electron, and the Planck’s constant, as explains physicist and astrobiologist Paul Davies to Cosmos magazine. Appearing at the intersection of such key areas of physics as relativity, electromagnetism and quantum mechanics is what gives 1/137 its allure.

Physicist Laurence Eaves, a professor at the University of Nottingham, thinks the number 137 would be the one you’d signal to the aliens to indicate that we have some measure of mastery over our planet and understand quantum mechanics. The aliens would know the number as well, especially if they developed advanced sciences.

The number preoccupied other great physicists as well, including the Nobel Prize winning Wolfgang Pauli (1900-1958) who was obsessed with it his whole life.

“When I die my first question to the Devil will be: What is the meaning of the fine structure constant?” Pauli joked.

Pauli also referred to the fine structure constant during his Nobel lecture on December 13th, 1946 in Stockholm, saying a theory was necessary that would determine the constant’s value and “thus explain the atomistic structure of electricity, which is such an essential quality of all atomic sources of electric fields actually occurring in nature.”

One use of this curious number is to measure the interaction of charged particles like electrons with electromagnetic fields. Alpha determines how fast an excited atom can emit a photon. It also affects the details of the light emitted by atoms. Scientists have been able to observe a pattern of shifts of light coming from atoms called “fine structure” (giving the constant its name). This “fine structure” has been seen in sunlight and the light coming from other stars.

The constant figures in other situations, making physicists wonder why. Why does nature insist on this number? It has appeared in various calculations in physics since the 1880s, spurring numerous attempts to come up with a Grand Unified Theory that would incorporate the constant since. So far no single explanation took hold. Recent research also introduced the possibility that the constant has actually increased over the last six billion years, even though slightly.

If you’d like to know the math behind fine structure constant more specifically, the way you arrive at alpha is by putting the 3 constants h,c, and e together in the equation —

As the units c, e, and h cancel each other out, the “pure” number of 137.03599913 is left behind. For historical reasons, says Professor Davies, the inverse of the equation is used 2πe2/hc = 1/137.03599913. If you’re wondering what is the precise value of that fraction – it’s 0.007297351.

Now, as I said in my introduction, I don’t understand this. But it doesn’t stop me from marvelling at the figure.

Wolves on Michigan’s Isle Royale reveal new info about predator-prey relationships

This we know: Top carnivores profoundly influence local ecosystems.

By STARRE VARTAN  October 26, 2018.

The American people’s relationship with top predators — especially wolves — is complex and ever-evolving. About three decades ago, it was mostly just animal-rights groups and their supporters who fought for the wolves’ right to exist; they were often considered a nuisance. But now there’s plenty of scientific evidence proving what’s good for wolves is good for their prey, the plants those prey eat, and indeed, positively affects the entire ecosystem. That’s ultimately good for humans too — unless you’re competing with the wolves, like a rancher who grazes animals or a hunter who wants to shoot the same deer or moose that wolves need to eat. But at this point, even some ranchers and hunters have come over to the pro-predator side.

Much of that change in the perception of predators is down to studies that have proven how precisely cougars, wolves, bears, tigers, lions, bald eagles, alligators and other apex predators affect the land around them. None have been studied longer than the wolves and moose in Isle Royale National Park, a Guam-sized island in Lake Superior. For almost 60 years, the populations of these two groups have been tracked — as well as their effects on the plants and other animal communities on the island. (You can read the reports here, including the recent 59th annual report.)

As the video above explains, there used to be as many as 50 wolves on Isle Royale; however, that number has dwindled, mostly due to inbreeding that caused a debilitating spinal condition to proliferate among the too-closely-related wolves. Just 10 years ago, there were still around 30 wolves but by 2015, there were only three wolves left. Now, there are just two, a closely related male-female pair that probably won’t breed. (The female of the pair has aggressively fought back when the male attempted to breed with her.)

Already, the moose population on the island has boomed, “undoubtably because of lack of predation,” John Vucetich, a wildlife ecologist from Michigan Technological University told Science magazine, adding that the two remaining wolves are now “… swimming in moose.” Despite the wolves’ regular predation on moose, there’s been a 20 percent increase in moose in just one year, which scientists estimate is about five to 10 times higher than on mainland areas. Beaver populations have also risen sharply. There’s just not enough wolves to keep either population in check.

So what’s so bad about so many moose? Well, as most ungulates do, moose spend their days browsing on vegetation, so the more moose, the more food they need — and the plants on the island can only take so much nibbling. An aquatic plant, which was found in abundance just six years ago, is now only found in places where moose are not. Long-term, this means the island will soon run out of food to keep the ever-larger moose population alive, and many will starve once food becomes scarce. Previously, the wolves have kept moose populations low enough so they didn’t overeat the vegetation, keeping the system in balance.

A plan to rebalance the ecosystem

This female wolf arrived at Isle Royale on Oct. 2, 2018. (Photo: NPS/Jim Peaco)

This is why some people think the best solution is to bring a fresh influx of wolves to Isle Royale National Park. The plan is to release 25-30 wolves over the next three to five years. So far, park officials have trapped four wolves on the mainland beginning in late September and released them on the island. Three of the wolves are female — with the hope they will successfully breed.

This new blood would potentially rebalance the predator-prey relationship and the idea is that the rest of the ecosystem would follow. Introducing so many wolves over several years is hardly natural either, others argue, saying that humans should just be hands off and let nature take its course. The original 50 wolves had found their way to the island on their own, having moved in from Canada; perhaps they could do so again if given the chance.

Here’s a news item taken from CBS News.

Then for those that would like more background on the Orca whale, let me republish the opening paragraphs of an item from Wikipedia.

The killer whale or orca (Orcinus orca) is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. Killer whales have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as seals and dolphins. They have been known to attack baleen whale calves, and even adult whales. Killer whales are apex predators, as no animal preys on them. A cosmopolitan species, they can be found in each of the world’s oceans in a variety of marine environments, from Arctic and Antarctic regions to tropical seas, absent only from the Baltic and Black seas, and some areas of the Arctic Ocean.

Killer whales are highly social; some populations are composed of matrilineal family groups (pods) which are the most stable of any animal species. Their sophisticated hunting techniques and vocal behaviours, which are often specific to a particular group and passed across generations, have been described as manifestations of animal culture.

The International Union for Conservation of Nature assesses the orca’s conservation status as data deficient because of the likelihood that two or more killer whale types are separate species. Some local populations are considered threatened or endangered due to prey depletion, habitat loss, pollution (by PCBs), capture for marine mammal parks, and conflicts with human fisheries. In late 2005, the southern resident killer whales, which swim in British Columbia and Washington statewaters, were placed on the U.S. Endangered Species list.

Wild killer whales are not considered a threat to humans,[6] but there have been cases of captive orcas killing or injuring their handlers at marine theme parks. Killer whales feature strongly in the mythologies of indigenous cultures, with their reputation ranging from being the souls of humans to merciless killers.

A Letter to Mr. Cosmos, Page Two

The concluding part of my letter to Mr. Cosmos.

Your Universe, Mr. Cosmos, is an enormous place.

Just the view at night from one small planet, the one that I happen to live on, Planet Earth, reveals millions upon millions of stars. It is then beyond inconceivable that there are not, in turn, countless numbers of other planets.

Extending this line of thought and recognising that a ‘mere’ billion years after the formation of our solar system and Planet Earth, some 4.54 billion years ago, the earliest life appeared, we can’t surely be alone!

Granted it was only cyanobacteria, as in blue-green algae, but, but, but ……… that this evolution of life on Planet Earth, and that evolution eventually leading to intelligent life, including the gift to us humans of the genetic separation of the dog from the wolf some 100,000 years ago, has not occurred on other planets is also totally inconceivable.

So, dear Mr. Cosmos, why have we not detected any signs of that intelligent life. Where are they?

Mr. Cosmos, back in June this year there was an article on the Big Think site that asked just this question.

Are we alone in the universe? New Drake equation suggests yes

A fresh take on the decades-old Drake equation incorporates new factors and greater uncertainty, suggesting a high likelihood that humanity is alone in the universe.

By STEPHEN JOHNSON, 25th June, 2018

At the Los Alamos National Laboratory in 1950, physicist Enrico Fermi famously posed to his colleagues a simple question borne of complex math: ‘Where are they?’

He was asking about aliens—intelligent ones, specifically. The Italian-American scientist was puzzled as to why mankind hasn’t detected any signs of intelligent life beyond our planet. He reasoned that even if life is extremely rare, you’d still expect there to be many alien civilizations given the sheer size of the universe. After all, some estimates indicate that there is one septillion, or 1,000,000,000,000,000,000,000,000, stars in the universe, some of which are surrounded by planets that could probably support life.

So, where are they, and why aren’t they talking to us?

Now, as the article reveals, there is a lot to tackling this question, much of it involving statistics and mathematics, but it does prove one very important fact: Finding another planet as good for life and humanity as this one is just about impossible.

This is our only home!!

My wish, dear Mr. Cosmos, to you is this: That before I die it becomes clear beyond question that the peoples of this sweet Planet, from the lone individual living on some island out in the wilderness to the Governments of the most powerful nations on Earth, understand that nothing is more important than loving, caring for and looking after Planet Earth.

I remain, dear Mr. Cosmos, your respectful servant.

A Letter to Mr. Cosmos, Page One

The last in this recent series on me examining my navel!

Dear Mr. Cosmos,

Clearly, I have no idea how many letters you receive from us funny inhabitants on Planet Earth. Can’t imagine you get floods of them but then neither can I imagine that this is the first one you have ever received.

Why can I not imagine this is to be your first? Simply, because us funny folk on this incredible planet of yours have been around for quite a while. I mean that over in that country we folk call Israel there has been found evidence of “control of fire by humans nearly 790,000 years ago.”

Whoops!

Just realised that me saying “quite a while” and writing of “790,000 years ago” will be utterly meaningless, in terms of scale, to how you describe your past. Just as it is utterly meaningless for me to contemplate that in cosmological terms the ‘Big Bang”, generally recognised as the start of your Universe, was, give or take, some 13.8 billion years ago.

I wish I could really get an idea of what a million years feels like, let alone a billion years. Ah well!

Let me stay with this notion of stuff being meaningless.

My dear, long-time friend Dan Gomez sent me a link to an item that had been published on the Science Alert website. It was about how the NASA Hubble space telescope had recently embarked on a new mission. Or in the words of that article:

Hubble Just Revealed Thousands of Hidden Galaxies in This Jaw-Dropping Photo

By Michelle Starr, September 13th, 2018

Hubble has embarked on a new observation mission: to study the farthest reaches of the Universe, using some of the most massive objects in the Universe – galaxy clusters.

And this newly released picture shows how.

At the centre is Abell 370, a cluster of a few hundred galaxies located around 4 billion light-years from Earth. And arrayed around it, never seen before, are thousands of galaxies, out even farther in the depths of space.

The reason we can see them now is because of Abell 370. All those hundreds of galaxies, clustered so close together, and the associated dark matter, create an immense field of gravity.

When the light behind that field passes through it, the gravitational force is so strong that it bends the path of the light. This creates a magnifying effect called gravitational lensing, allowing us to see objects we usually can’t.

Abell 370 is the first of these clusters.

Here is one of those photographs,

(NASA, ESA, A. Koekemoer, M. Jauzac, C. Steinhardt, and the BUFFALO team)

And an explanation of what we are looking at:

In the image, you can see the galaxies in Abell 370. The brightest yellowish white ones are huge, containing hundreds of billions of stars. The bluer ones are smaller, spiral galaxies, like the Milky Way, with younger populations of stars. And the dimmer, yellower galaxies are older, with ageing star populations.

The galaxies behind Abell 370 appear as smeared lines of light. The most spectacular, to the lower left of the centre, is nicknamed the Dragon (possibly for its resemblance to a Chinese dragon), with its head to the left. It’s made up of five images of the same spiral galaxy, magnified and stretched by the gravitational lens.

Mr. Cosmos, you know a little earlier I was remarking about how it is impossible to comprehend the age of the Universe. Well, dear Sir, it’s just as impossible to comprehend your distances.

Take Abell 370 out there some 4 billion light years from Planet Earth! I really wanted to have a go at understanding that distance.

First, I looked up the distance in miles that is represented by one light-year. Answer: one light year is a tad under six trillion miles.

Just one, let alone some 4 billion of them!

Next, I looked up the distance of our very familiar Big Dipper constellation. You must have heard of it? This one!

The Big Dipper. Image Credit & Copyright: Jerry Lodriguss

Turns out that even this very familiar sight in our night sky ranges from 78 to 123 light years away. Average that as 100 light years and, bingo, you are looking at this familiar cluster of stars that is 590 trillion miles away!

So, dear Mr. Cosmos, that puts your Abell 370 constellation about a distance that is 10 million times more distant than our Big Dipper!

I wrote above that “I really wanted to understand that distance.” In reference to how far that Abell 370 constellation truly was.  My conclusion is that I will never, ever understand that distance.

Anyone able to help?

Tomorrow, Mr. Cosmos, the closing page two of my letter to you.

 

Science and the ocean floor

Scientists have been drilling into the ocean floor for 50 years – here’s what they’ve found so far

September 26, 2018

By Professor Suzanne O’Connell, Professor of Earth & Environmental Sciences, Wesleyan University

It’s stunning but true that we know more about the surface of the moon than about the Earth’s ocean floor. Much of what we do know has come from scientific ocean drilling – the systematic collection of core samples from the deep seabed. This revolutionary process began 50 years ago, when the drilling vessel Glomar Challenger sailed into the Gulf of Mexico on August 11, 1968 on the first expedition of the federally funded Deep Sea Drilling Project.

I went on my first scientific ocean drilling expedition in 1980, and since then have participated in six more expeditions to locations including the far North Atlantic and Antaractica’s Weddell Sea. In my lab, my students and I work with core samples from these expeditions. Each of these cores, which are cylinders 31 feet long and 3 inches wide, is like a book whose information is waiting to be translated into words. Holding a newly opened core, filled with rocks and sediment from the Earth’s ocean floor, is like opening a rare treasure chest that records the passage of time in Earth’s history.

Over a half-century, scientific ocean drilling has proved the theory of plate tectonics, created the field of paleoceanography and redefined how we view life on Earth by revealing an enormous variety and volume of life in the deep marine biosphere. And much more remains to be learned.

Technological innovations

Two key innovations made it possible for research ships to take core samples from precise locations in the deep oceans. The first, known as dynamic positioning, enables a 471-foot ship to stay fixed in place while drilling and recovering cores, one on top of the next, often in over 12,000 feet of water.

Anchoring isn’t feasible at these depths. Instead, technicians drop a torpedo-shaped instrument called a transponder over the side. A device called a transducer, mounted on the ship’s hull, sends an acoustic signal to the transponder, which replies. Computers on board calculate the distance and angle of this communication. Thrusters on the ship’s hull maneuver the vessel to stay in exactly the same location, countering the forces of currents, wind and waves.

Another challenge arises when drill bits have to be replaced mid-operation. The ocean’s crust is

The re-entry cone is welded together around the drill pipe, then lowered down the pipe to guide reinsertion before changing drill bits. IODP, CC BY-ND

composed of igneous rock that wears bits down long before the desired depth is reached.

When this happens, the drill crew brings the entire drill pipe to the surface, mounts a new drill bit and returns to the same hole. This requires guiding the pipe into a funnel shaped re-entry cone, less than 15 feet wide, placed in the bottom of the ocean at the mouth of the drilling hole. The process, which was first accomplished in 1970, is like lowering a long strand of spaghetti into a quarter-inch-wide funnel at the deep end of an Olympic swimming pool.

Confirming plate tectonics

When scientific ocean drilling began in 1968, the theory of plate tectonics was a subject of active debate. One key idea was that new ocean crust was created at ridges in the seafloor, where oceanic plates moved away from each other and magma from earth’s interior welled up between them. According to this theory, crust should be new material at the crest of ocean ridges, and its age should increase with distance from the crest.

Part of a core section from the Chicxulub impact crater. It is suevite, a type of rock, formed during the impact, that contains rock fragments and melted rocks. IODP, CC BY-ND

The only way to prove this was by analyzing sediment and rock cores. In the winter of 1968-1969, the Glomar Challenger drilled seven sites in the South Atlantic Ocean to the east and west of the Mid-Atlantic ridge. Both the igneous rocks of the ocean floor and overlying sediments aged in perfect agreement with the predictions, confirming that ocean crust was forming at the ridges and plate tectonics was correct.

Reconstructing earth’s history

The ocean record of Earth’s history is more continuous than geologic formations on land, where erosion and redeposition by wind, water and ice can disrupt the record. In most ocean locations sediment is laid down particle by particle, microfossil by microfossil, and remains in place, eventually succumbing to pressure and turning into rock.

Microfossils (plankton) preserved in sediment are beautiful and informative, even though some

are smaller than the width of a human hair. Like larger plant and animal fossils, scientists can use these delicate structures of calcium and silicon to reconstruct past environments.

Thanks to scientific ocean drilling, we know that after an asteroid strike killed all non-avian dinosaurs 66 million years ago, new life colonized the crater rim within years, and within 30,000 years a full ecosystem was thriving. A few deep ocean organisms lived right through the meteorite impact.

Ocean drilling has also shown that ten million years later, a massive discharge of carbon – probably from extensive volcanic activity and methane released from melting methane hydrates – caused an abrupt, intense warming event, or hyperthermal, called the Paleocene-Eocene Thermal Maximum. During this episode, even the Arctic reached over 73 degrees Fahrenheit.

The resulting acidification of the ocean from the release of carbon into the atmosphere and ocean caused massive dissolution and change in the deep ocean ecosystem.

This episode is an impressive example of the impact of rapid climate warming. The total amount of carbon released during the PETM is estimated to be about equal to the amount that humans will release if we burn all of Earth’s fossil fuel reserves. Yet, an important difference is that the carbon released by the volcanoes and hydrates was at a much slower rate than we are currently releasing fossil fuel. Thus we can expect even more dramatic climate and ecosystem changes unless we stop emitting carbon.

Finding life in ocean sediments

Scientific ocean drilling has also shown that there are roughly as many cells in marine sediment as in the ocean or in soil. Expeditions have found life in sediments at depths over 8000 feet; in seabed deposits that are 86 million years old; and at temperatures above 140 degrees Fahrenheit.

Today scientists from 23 nations are proposing and conducting research through the International Ocean Discovery Program, which uses scientific ocean drilling to recover data from seafloor sediments and rocks and to monitor environments under the ocean floor. Coring is producing new information about plate tectonics, such as the complexities of ocean crust formation, and the diversity of life in the deep oceans.

This research is expensive, and technologically and intellectually intense. But only by exploring the deep sea can we recover the treasures it holds and better understand its beauty and complexity.

Did the phrase in the first paragraph of the article jump out for you as it did for me?

This one: “…we know more about the surface of the moon than about the Earth’s ocean floor.”

A Letter to Mr. Neptune

Continuing my series on examining my navel.

Dear Mr. Neptune,

Your oceans of the world are truly breath-taking. The power you can display in the odd wave or million through to the tranquility you so often also display defy rational explanations.

I have had the profound experience of sailing upon your waters, dear Mr. Neptune, over a number of years sailing back and forth between Cyprus and Turkey. Not a long distance but still sufficient to experience being solo on a yacht day and night.

Tradewind 33 – Songbird of Kent. My home for five years.

Then on my way sailing back to Plymouth, SW England, the magical, almost primeval, feeling of being alone on the Atlantic Ocean. Looking up at the night sky, feeling so insignificant, so infinitesimally minute with 500 miles of open ocean in all directions and those stars above my head.

No question, that practically everything about your oceans is beyond the understanding of us humans. Indeed, I had to look up online how much water there is on Earth to discover there is:

It’s roughly 326 million cubic miles (1.332 billion cubic kilometers), according to a recent study from the U.S. Geological Survey.

Because I simply didn’t have a clue.

And knowing there are approximately 326 million cubic miles of water doesn’t help because I am still left not having a clue as to what that means!

So, thank goodness, Mr. Neptune this is all a ‘walk in the park’ for you!

But I do have a question for you.

What do you make of this?

The image is cropped from the following:

The description of these figures is:

Figure. (upper) Change in global upper-level (0–2000 m) ocean heat content since 1958. Each bar shows the annual mean relative to a 1981–2010 baseline. (lower) Annual mean ocean heat content anomaly in 2017 relative to a 1981–2010 baseline.

And it was taken from research undertaken by Lijing Cheng and Jiang Zhu and found on the web here.

Ocean Heat Content

Owing to its large heat capacity, the ocean accumulates the warming derived from human activities; indeed, more than 90% of Earth’s residual heat related to global warming is absorbed by the ocean (IPCC, Cheng et al. 2017). As such, the global ocean heat content record robustly represents the signature of global warming and is impacted less by weather-related noise and climate variability such as El Niño and La Niña events (Cheng et al. 2018). On the other hand, ocean thermal expansion due to ocean temperature change contributes substantially (30%~50%) to the sea level change, which can considerably influence human populations in coastal and island regions and marine ecosystems. Therefore, monitoring the OHC changes and understanding its variation are crucial for climate change.

Is it possible, Mr. Neptune, that even you as the master of all our oceans is worried about the future?

I hope not but I do fear your answer.

Sincerely,

Paul

Some archaeologists carry tools and painstakingly chip away at historic sites. Others might have fluffy bodies, keen senses of smell and an affinity for digging stuff up.

As Tom McEnchroe reports for Radio Praha, a very good dog named Monty recently unearthed a rare trove of Bronze Age artifacts near the Czech village of Kostelecké Horky. Monty was walking with his human, identified as “Mr. Frankota,” in a field when he began pawing frenetically at the ground. Soon, thanks to Monty’s hard work, metallic objects began to emerge in the soil.

The cache of relics includes 13 sickles, two spear points, three axes and several bracelets. The objects have been dated to the Urnfield period around 3,000 years ago. This late European Bronze Age culture is marked by the transition from inhumation burials to cremations; the remains of the dead were interred in urns, giving the era its name. According to Encyclopaedia Britannica, Urnfield culture first appeared in east-central Europe and northern Italy, but eventually spread “to Ukraine, Sicily, Scandinavia, and across France to the Iberian peninsula.”

It is rare to find a cluster of intact Urnfield objects, according to a press release. “The culture that lived here at the time normally just buried fragments, often melted as well,” Martina Beková, an archaeologist at the Museum and Gallery of Orlické who studied the artifacts after they were discovered by Monty, tells McEnchroe. So she suspects that the relics were tied to a ritual—“most likely a sacrifice of some sorts,” Beková says.

Additional evidence could help pin down the function of the objects, and according to Michelle Starr of Science Alert, local archaeologists have been searching the area in the hopes of finding more relics. They haven’t uncovered anything yet, but Sylvie Velčovská, a spokeswoman for the region, tells McEnchroe that there have been, “considerable changes to the surrounding terrain over the centuries, so it is possible that the deeper layers are still hiding some secrets.”

The newly uncovered objects will be on display at the Museum and Gallery of Orlické Mountains in the town of Rychnov until October 21, after which point they will undergo conservation and be moved to a permanent exhibition in the village of Kostelec.

Frankota, Monty’s owner, was awarded 7860 Czech Koruna (around $360) for his role in alerting archaeologists to the ancient treasures. One can only hope that Monty was given many treats and pets for his superb fieldwork

Wolf pups born on Warm Springs Reservation

Holly M. Gill, Thursday, September 06, 2018

A male and a female wolf have been photographed with their two pups on the northern part of the reservation.

PHOTO COURTESY OF THE CONFEDERATED TRIBES OF WARM SPRINGS – Two wolf pups with the adult male of the pack are caught on a remote trail camera on the Warm Springs Reservation. The wolf pups are believed to be the first born on the reservation since the 1940s.

For at least the past four years, a large male wolf has been observed roaming parts of the Warm Springs Reservation. Now, the wolf, his mate and two pups have also been seen on trail cameras.

On Aug. 27, the Confederated Tribes of Warm Springs Branch of Natural Resources confirmed that the single male first observed in 2014, and his mate, first seen in 2016, have produced two pups.

“In early September 2014, biologists suspected that a large male wolf of unknown origin, more than likely from Northeast Oregon, had a mate on the Warm Springs Reservation and Mount Hood National Forest, when remote cameras captured several images of two or more wolves in the area,” said wildlife biologist Austin Smith Jr., of the tribes’ Natural Resources Branch.

PHOTO COURTESY OF THE CONFEDERATED TRIBES OF WARM SPRINGS – A female gray wolf from the Warm Springs/White River pack seems to be caught on a remote trail camera teaching her pup, on the right, how to howl. In August, the Confederated Tribes of Warm Springs’ Branch of Natural Resources caught the photos of the two adult wolves and two pups, which are estimated to be 3 to 4 months old.

“Initially, last year, we had been getting multiple reports from technicians and contractors working in the area, that there was a group of wolves in the area,” said Smith. “We were trying to verify that, but we couldn’t confirm that there was a pup.”

In August, Smith thought there might be new pups, so he and a high school intern walked to the “rendezvous site,” where the wolves had been seen last year. “We managed to track them to an area and we saw a pup, about the size of a dog. We saw it take off, and ended up setting up a camera.”

After they saw the pup, Smith notified the U.S. Fish and Wildlife Service, which keeps track of wolf activity. At the end of 2017, Oregon had at least 124 gray wolves, including two known as the White River pair.

“They are in the southern portion of Wasco County, the northern part of the reservation, and the White River wildlife management area,” said Smith. “ODFW named the pack off of what area they’re covered in. We call them the Warm Springs pack.”

With assistance from USFW Biologist John Stephenson, the tribes set up remote trail cameras, which have been yielding numerous images of the wolves, including the pups.

“I was pretty surprised,” said Smith, noting that the pups are the first verified instance of wolves reproducing on the reservation since the mid-1940s. “It was the first time we had officially seen wolf pups.”

Gray wolves, which had historically been common in Oregon, were eradicated in the late 1940s. In 1974, wolves were listed as endangered by the federal Endangered Species Act. The state enacted its own Endangered Species Act in 1987, requiring the Oregon Department of Fish and Wildlife to conserve wolves.

According to ODFW, the wolves in Oregon are part of the Northern Rocky Mountain wolf population, which was reintroduced in Idaho and Yellowstone National Park in the mid-1990s. The first wolf made its way to Oregon in the late 1990s.

Over the past decade, the documented population of wolves in Oregon has increased from about three in 2008, to 14 at the end of 2009, to 124 at the end of 2017. Most packs are located in Northeast Oregon.

Wolves have been wandering through Oregon for years, but the new group seems to have established itself on the reservation, said Smith. “Once they’re a breeding pair, they officially become a pack.”

Smith said that the wolves are an important resource on the reservation. “They’re a culturally significant and sensitive species,” he said. “They usually pick an area where they have enough food source. The numbers of deer and elk have increased on the reservation.”

The wolf pups are probably 3 to 4 months old, and weigh 75 to 100 pounds, he estimated.

“Typically, when they’re in the denning period, it runs from spring until early summer,” said Smith. “During that time, the female will stay in the den, while the male and siblings are out hunting. They will bring back food for the female.”

“Typically, they’re out of the den after a couple months, and pretty mobile by then,” he said. “These pups were probably born in June.”

The tribes’ Branch of Natural Resources will continue to monitor the pack and its movements to ensure an accurate population count.

I must repeat what was quoted as being said by Austin Smith Jr. because it so perfectly explains what we see in our dogs. (My emphasis.)

Smith said that the wolves are an important resource on the reservation. “They’re a culturally significant and sensitive species,” he said.

Well done Oregon and in particular well done the good folk of the Warm Springs Reservation.

Here are a couple of photographs I found online to share with you.
