#AceNewsDesk – The world’s human population is forecast to surpass 8 billion in the coming months. But we’ve got nothing on ants.

Researchers have made the most thorough assessment to date of the global population of ants — insects that have colonised almost everywhere on the planet — and the estimated total is a mind-blowing 20 quadrillion of them, or approximately 2.5 million for every human.

It should come as little surprise considering how ubiquitous these busy and social insects are.

They have thrived since the age of dinosaurs, with the oldest-known ant fossil dating back about 100 million years to the Cretaceous Period.

“Ants certainly play a very central role in almost every terrestrial ecosystem,” said entomologist Patrick Schultheiss of Germany’s University of Würzburg and the University of Hong Kong, co-lead author of the study published in the journal Proceedings of the National Academy of Sciences.

“They are very important for nutrient cycling, decomposition processes, plant seed dispersal and the perturbation of soil.

“Ants are also an extremely diverse group of insects, with the different species fulfilling a wide range of functions.

“But most of all, it is their high abundance that makes them key ecological players.”

There are more than 12,000 known species of ants, which generally are black, brown or red in colour and possess bodies segmented into three parts.

Ranging in size from about 1 millimetre to 3 centimetres long, ants typically inhabit soil, leaf litter or decaying plants — and occasionally our kitchens.Ants generally live in colonies, sometimes consisting of millions of them divided into groups.(Supplied: David Hu)none

Ants, whose closest relatives are bees and wasps, are native to nearly everywhere on Earth, as any picnicker knows, except Antarctica, Greenland, Iceland and some island nations.

“I was amazed that the ants’ biomass was higher than that of wild mammals and birds combined, and that it reaches 20 per cent of the human biomass,” said insect ecologist and study co-lead author Sabine Nooten, also of the University of Würzburg and University of Hong Kong.

“That gives you an understanding of the scale of their impact.

“I find the enormous diversity of ants fascinating.

“They can be tiny or huge and show the most bizarre adaptations,” she added, citing a widespread ant genus called Strumigenys, known for long mouth parts with spikes used to hunt small invertebrates.

The researchers based their analysis on 489 studies of ant populations spanning every continent where ants live.

“Our dataset represents a massive collecting effort of thousands of scientists,” Dr Schultheiss said.

“We were then able to extrapolate the number of ants for different regions of the world and estimate their total global number and biomass.”Australia has a crazy ant problem

‘Most ants are actually highly beneficial’

Tropical regions were found to harbour many more ants than other regions, with forests and drylands boasting more ants than urban areas.

“There are certain parts of the world where we have little data and we cannot reach reliable estimates for all continents. Africa is one such example. We have long known that it is a very ant-rich continent, but also very under-studied,” Dr Schultheiss said.

Ants generally live in colonies, sometimes consisting of millions of them divided into groups with different roles such as workers, soldiers, and queens.

The workers, all females, care for the bigger queen and her offspring, maintain the nest, and forage for food.

Males mate with queens, then die.

“Some ants can certainly be very annoying, but that’s a very human-centered perspective,” Dr Schultheiss said.

“Most ants are actually highly beneficial, even to us humans.

“Think about the amount of organic matter that 20 quadrillion ants transport, remove, recycle and eat.

“In fact, ants are so essential for the smooth working of biological processes that they can be seen as ecosystem engineers.

“The late ant scientist EO Wilson once called them ‘the little things that run the world.'”

Dr Chris Burwell, a senior curator of insects from Queensland Museum, said the study emphasised the integral role ants play in our ecosystems.

“Having that estimate of the numbers; I know ants are important, but they are really important given the sheer number of them,” said Dr Burwell, who was not involved with the study.

“It’s not each ant as the individual, but the colony we regard as the individual. Colonies are the equivalent of an animal or a mammal in the ecosystem.

“There have been studies done where they estimate the ants walking around on the surface, and it’s a fraction of the ants living in the colony — so you’re seeing a small amount of the ants that are out there.

“That estimation compared to humans, it tells you there’s a lot of ants, but also shows you there are a lot of humans.”Think about the amount of organic matter that 20 quadrillion ants process.(Adobe Stock)none

FEATURED CREATION REPORT: Tiny oysters play big role in stabilizing eroding shorelines as sea-levels rise threatening communities

#AceNewsDesk – As sea levels rise and buildings by coasts are increasingly endangered, communities around the world are turning to the small but mighty oyster to help stabilize shorelines according to

LACEY TOWNSHIP, N.J. — Denise Vaccaro bought her home on the Jersey Shore over 20 years ago, charmed by the little beach at the end of a sandy spit on Barnegat Bay where she could sit and read while listening to the waves and enjoying the cool breezes.

That home was destroyed 10 years ago in Superstorm Sandy, and the beach she loved is also gone, claimed by rising seas that are eroding the shoreline and pushing water to porches.

“It’s so sad that this little community has lost its beach,” Vaccaro said. “People are losing their property. My home was totally destroyed. It’s a way of life that’s being lost.”

It’s a story being played out on shorelines all around the world as once idyllic beach communities are washing away, and residents are struggling to adapt.

But a partial solution being tried around the world is also being done here: establishing oyster colonies to form natural barriers that blunt the force of waves and help stabilize eroding shorelines.

Such a project is underway near Vaccaro’s rebuilt house, carried out by the American Littoral Society, which received a $1 million grant from the New Jersey Department of Environmental Protection. The group has been building steel wire cages, filling them with rocks and whelk shells and positioning them in rows along the shoreline of Barnegat Bay.

Tiny baby oysters, called spat, are attached to whelk shells and placed in the bay near the existing cages to further stabilize the shoreline.

The shoreline in Vaccaro’s neighborhood has lost 150 feet (46 meters) of beach since 1995, according to the Littoral Society.

In much of it, there is no sand at all; waves pound against grassy mounds that are getting smaller all the time. A shuffleboard court that used to be part of a wide beach with plenty of sand between it and the bay is now halfway submerged in water.

“Some of the people along this shoreline have seen the bay swallow their back porches, more than one,” said Julie Schumacher, habitat restoration coordinator for the Littoral Society. “The water is right up against them.”

The rows of oysters appear to be doing their job as effective breakwaters. One recent day, a strong east wind rippled the bay with whitecaps out beyond the oysters. But between the oysters and the shoreline, the water was much calmer, and waves sloped gently onto the shoreline instead of pounding against it.

As an added benefit, the oysters help improve water quality in the bay: A single oyster can filter up to 50 gallons (190 liters) of water a day.

Projects like this one are an important part of New Jersey’s coastal resilience program — using plants and shellfish beds to create “living shorelines” that complement engineered structures like sea walls and bulkheads to protect homes and people.

A few miles south, a group called ReClam the Bay is building an oyster reef to protect the shoreline of Mordecai Island, an uninhabited patch of land that in turn protects the shoreline of Beach Haven, a popular resort town on Long Beach Island.

Volunteers fill mesh bags with 35 pounds (16 kilograms) of whelk shells, to which millions of baby oysters have been attached, then sail them out to the reef a few hundred yards offshore. They’ve placed 10,000 bags of oysters and whelk shells there since 2015.

“In the last 100 years, Mordecai Island has lost 35% of its size,” said Jack Duggan, a longtime volunteer with the group. “If we do nothing, in 40 years the island will be gone — just washed over. This island protects Beach Haven from taking the force of all that wave action.”

ReClam The Bay has done a similar project establishing an oyster reef in front of a brick wall in Tuckerton, further north in the bay, and the Littoral Society has numerous other oyster projects underway. At the Naval Weapons Station Earle in Middletown, the NY/NJ Baykeeper organization is growing oysters along the heavily guarded pier and deploying them along the shoreline to protect the coast, which suffered serious erosion during Sandy.

Governments and volunteers in other places are doing the same thing.

In New York, city, state and federal agencies are building “living shorelines” along the southwestern tip of Long Island, using oysters, shells and native plants. A similar project in Delaware used 1,300 bags of shells to extend shoreline protection near Lewes CanalFront Park.

The Oyster Recovery Partnership in Maryland has placed billions of oysters on shells in Chesapeake Bay in a project set to run through 2025. In Florida, volunteers and researchers established oyster colonies along portions of the Peace River in Punta Gorda.

In California, the Wild Oyster Project is establishing reefs in San Francisco Bay for shoreline protection and water quality improvement purposes.

In Argyll, Scotland, a group called Seawilding began restoring an area in 2020 near a coastal inlet that had become degraded. They’ve restored more than 300,000 oysters there. Also in Scotland, a project aims to restore 30,000 oysters near Edinburgh.

Vaccaro realizes her New Jersey home may well depend on the success of a bunch of tiny oysters.

“If we don’t do anything, we’re not going to have any of these houses,” Vaccaro said. “In 20 years my house — which I rebuilt on pilings — could be gone again. This is why what we’re doing here is so important to me. I saw what happened and I see what can happen again.”

In the Diego Ramirez Islands, 100km from southern Chile’s Cape Horn, scientists have identified the Subantarctic rayadito, a 16g brown bird with black and yellow bands, and a large beak that is confounding biologists.

That’s because the Subantarctic rayadito, which resembles a rayadito species that inhabits the forests of southern Patagonia and nests in trunk cavities, was found “living in a place with no trees.”

“There are no bushes and no woodland species, literally in the middle of the ocean a forest bird has managed to survive,” said Ricardo Rozzi, an academic from Chile’s University of Magallanes and the University of North Texas and director of the Cape Horn International Center for Global Change Studies and Biocultural Conservation (CHIC).

The finding, reported in the science journal Nature, was made after a six-year investigation in which the tiny bird became an “obsession” to researchers, said Mr Rozzi.

One of the researchers, Rodrigo Vasquez, a biologist at the University of Chile, said that genetic studies confirmed that the newly discovered species “differs in a mutation from the rest of the species of the classic rayadito species,” in addition to other differences in form and behavior.

The researchers said they had captured and measured 13 individuals on the island:

“The Birds from the Diego Ramirez population were significantly heavier and larger (with a longer and wider bill and longer tarsi), but they had a significantly shorter tail,” they said in Nature.

To Mr Rozzi, the species could become “a symbol … that will contribute to the knowledge” about the little-known Diego Ramirez Islands.

FEATURED AUSTRALIA: Dugongs Virtually Extinct in China How are they Doing Here ?

This is our daily post that is shared across Twitter & Telegram and published first on here with Kindness & Love XX on peace-truth.com/

#AceNewsDesk – Study finds dugongs are functionally extinct in Chinese waters. So how is the population in Australia?

Researchers have found that here are more than 12,000 dugongs in the Kimberley.
An Australian reseracher says there are areas of concern for dugong habitats in Australian waters. (ABC Kimberley: Supplied)none

The dugong has become functionally extinct in waters off China, a new study has found. 

Researchers from the Zoological Society of London and the Chinese Academy of Sciences said fishing, ship strikes and human-caused habitat loss had seen the number of dugongs in Chinese waters decrease rapidly since the 1970s. 

Let’s take a look at why this is the case and how dugong habitats in Australia are tracking. 

Finding in China a ‘wake up call’ 

According to the report, it is the “first functional extinction of a large mammal in China’s coastal waters”. 

Dugongs have been classified as a national key protected animal since 1988 by China’s Sate Council.

However, despite restoration and recovery efforts being a priority it “takes time that dugongs may no longer have,” the report said.

For the study, scientists conducted interviews in 66 fishing communities across four Chinese provinces along the coastal region of the South China Sea.

Samuel Turvey, a co-author of the study, said the likely disappearance of dugongs in China was a devastating loss.

“Their absence will not only have a knock-on effect on ecosystem function, but also serves as a wake-up call,” Professor Turvey said.

“[It is] a sobering reminder that extinctions can occur before effective conservation actions are developed.”

Australia an ‘important place’ for dugongs 

Australia has been the most important place for dugongs for several thousands of years.

That’s according James Cook University environmental scientist Helene Marsh.

She researches dugong population ecology and chairs the national Threatened Species Scientific Committee.

“In Australia, they have enormous cultural value to Indigenous people and they also have major biodiversity values because they’re very strange animals,” Professor Marsh said.

“They are different from most other marine mammals, with the exception of manatees, and their closest terrestrial relatives is the elephant.

“They are the stuff of mermaid legend.”

The finding in China did not surprise Professor Marsh.

She said in comparison to the rest of the world dugongs off Australia were fairing well.

“In northern Australia we have a very wide continental shelf which supports extensive seagrass beds and so we can support a lot more dugongs, because we have got the habitat, than anywhere else,” she said.

Despite this, there are some areas of concern.

Extreme events destroying seagrass

According to the Australian Marine Conservation Society dugongs are dependant on shallow coastal waters and are vulnerable to rising sea levels.

Extreme weather events are putting pressure on seagrass, which is critical to the survival of dugongs.

“It is very concerning that we can get extreme weather events, some of which are likely to become more common with climate change, that destroy sea beds and then effect dugongs,” Professor Marsh said.

This year’s floods in Queensland destroyed large areas of seagrass in dugong habitats off Hervey Bay and Moreton Bay.

“The seagrass will probably come back, but it’ll take a few years,” she said. 

“The dugongs have to move or starve.

“This has happened before and then they stop breeding. Some of them move and some of them stay and starve, and then you get more stranded animals.

“There have been some more reports of strandings in that general region [south east Queensland] this year and green turtles were effected similarly.

“The numbers so far haven’t been as serious as they were in 1992 and 1993, where I think the damage was more widespread.”

Torres Strait is Australia’s ‘dugong capital’ 

Professor Marsh said there is dieback of deep water seagrass in the Torres Strait but the cause of it was not known.

“There’s quite a bit of concern at the moment about the situation in Torres Strait,” she said.

“If Australia is the dugong capital of the world then the Torres Strait is the dugong capital of Australia and then the most important place for dugongs in the whole world.

“I think we tend to think more about places closer to home than in the remote areas such as the Torres Strait, although there is some active work going on at the moment,” Professor Marsh said.

Once Upon a Time @storyteller

❤️❤️

There was a bear 🐻 called Honey now that bear was called Honey – you guessed it because he loved Honey on his Porridge in the Morning for Breakfast 🐻

Now Honey worked in a mine – oh no not like any mine but a Honey mine where he would go every day and mine for Golden Honey which to the little bear, was just like Money and he would use what he mined and of course did not eat to ‘ Share ‘ with his friends Joel (Rat) Shoo She (Cat) and his very very best friend Jasper (The Tiger) and for many many years they were all Happy – Sharing & Caring for each other until one fateful day – Judas turned up and wanted to be friends with Honey and Honey being a – Kind & Generous Bear – Welcomed Judas -who by the way was a – Snake into the fold 🐻

For some days after Judas ingratiated himself with Honey and seeing him ‘ Sharing,’ the Honey for Free thought l can make some Money here and so hatched a plan and met up with the local Judge called Herod and discussed with him how they both could benefit by charging 30-pieces of silver for every batch of Honey – So it came to pass that a law was passed and every creature of creation including Honey would be Taxed 🐻

They all had to go to the Little Town of Bethlehem and arrange for taxation on all goods mined including – you got it Honey and every penny would be used to make their lives better – but of course, with every Judas comes Greed and most of the animals of Creation could not afford the Honey and so as happens everywhere in life – Greed stops Honey mining for Honey as he would have to sell it and nobody could afford 30 Pieces of Silver for each 🍯 container

Meanwhile Judas moves in his people and starts mining all the Honey for himself and his group of renegades and none is left for Poor Honey not a drop as Judas now a very Rich man has even started charging for the jars that Joel (Rat) makes and adding on a delivery charge on transporting it to market that Shoo Shoo (Cat) provides and finally adds an extra charge on retail that Honey’s best friend Jasper (Tiger) provided and slowly as always happens they all had to pay more and more

LO – Up in Heaven God looks down and sees all that Judas is doing and knows ‘ All Things Have Passed ‘ He must help Creation to survive and sends Adam to them to give them guidance on how to defeat the ‘ Evil ‘ Judas and his henchmen and so begins the ‘ Restoration ‘ Adam enters into the world in the ❤️ ❤️ of those that are in Need and God creates for them from that word Need by making it uncorrupted an Eden and into that Eden he put all things Good to Eat and brought all those living creatures damaged by Judas and put a wall around to protect Adam and all his living creation bringing it to one place to be safe and protected forevermore 🐻✨

Outside desolation happens and Judas no longer can ‘ Tax ‘ any creature as they are all safe and protected by God and so has to do all the work himself no longer holding any creature in bondage, hunted or just for sport and as with all thieves, liars, and murderers they fall out with each other and everyone wants to be top dog and eventually the ‘ Evil ‘ is wiped out and all that is left is ‘ Good ‘ now all the cleansing has taken place in people’s ❤️❤️‘s can come to pass with ‘Goodwill & Peace on Earth ‘ and God can remove the wall and ‘Sharing & Caring ‘ can begin once again

AMEN

Amen ✨🙏

#GlobalWarming & #ClimateChange – In the State of the Polar Bear Report 2021, published by the Global Warming Policy Foundation (GWPF) ahead of International Polar Bear Day tomorrow, zoologist Dr. Susan Crockford explains that while the IUCN Polar Bear Specialist Group (PBSG) promotes the impression that polar bear population numbers are declining, the results of recent studies indicate otherwise: London, 26 February – Polar bears are thriving, says prominent Canadian zoologist.

Susan Crockford: The State of the Polar Bear 2021 (pdf)

Polar bears continued to thrive in 2021

Crockford further clarifies that the global population estimate used by the PBSG has not been updated since 2015, even though the results of numerous surveys have been published since then.

These additions bring the global population total to almost 32,000, up from about 26,000, albeit with a wide range of potential error. This modest increase is consistent with a species recovering from low numbers brought about by overhunting after focused international protection was introduced in 1973.

In 2021, results of an aerial survey of the Chukchi Sea in 2016 generated a population estimate of 5,444 (range 3,636–8,152), about 2,500 greater than a previous survey but within its range of error. This estimate is in line with other evidence that conditions for polar bears in the area have been excellent.

Results from a 2017–2018 survey of the Davis Strait subpopulation published in 2021 revealed numbers were stable, although the bears were fatter than they had been in 2005-2007, with good cub survival indicating a thriving population.

Dr. Crockford reports that there were three serious attacks by polar bears on people in 2021 but no fatalities. She explains that there were no reports of widespread starvation of bears, acts of cannibalism, or drowning deaths that might suggest bears were having trouble surviving the ice-free season.

“The current health and abundance of polar bears continues to be at odds with predictions that the species is suffering serious negative impacts from reduced summer sea ice blamed on human-caused climate change.”

Key Findings

• Recent survey results bring the average global population estimate to at least 32,000, with a wide range of potential error.

• Results from the 2017–2018 survey of the Davis Strait subpopulation revealed numbers are stable at about 2,015 bears (range 1,603–2,588), but bears were found to have been fatter than they had been in 2005–2007, with good cub survival.

• An aerial survey of the Chukchi Sea in 2016 generated a population estimate of 5,444 (range 3,636–8,152), about 2,500 greater than a previous survey, which plausibly reflects the excellent conditions for polar bears in this area.

• Reports that polar bears seem to be moving from Alaska to Russia in a ‘mass exodus’ may describe a real phenomenon that reflects the excellent feeding conditions for bears in the Chukchi Sea compared to Alaska, fueled by continued increases in primary productivity across the Arctic.

• Spring research in Svalbard, Norway in 2021 showed body condition of male polar bears was stable and litter size of family groups was the same as it had been in 1994 but lower than 2019.

• A new paper reported that more polar bears in Svalbard seem to be killing and eating reindeer during the summer than they did during the 1970s but the phenomenon was not exclusively tied to reduced sea ice.

• Markus Dyck, a renowned Canadian polar bear biologist, died tragically 25 April 2021 in a helicopter crash near Resolute Bay along with two crew members while doing a survey of the Lancaster Sound subpopulation for the government of Nunavut

• There were three serious attacks by polar bears on people in 2021 but no fatalities: Foxe Basin (Canada) in August, Svalbard (Norway) in March, and northeast Greenland in August.

#GlobalWarming Rising Temperatures Are Turning Antarctica Green

This is our daily list of post that is shared across Twitter & Telegram and on here on My.Daz.blog

‘Ace News Room With Kindness & Love❤️❤️’ , Feb.19, 2020 @AceDailyNews 

This just in from the cutting room floor 19/02/2022: 

#ClimateChange Causing Native flowering plant species to grow faster and more densely in the last decade than in the previous 50 years combined: Antarctic pearlwort (pictured) , grew and spread five times faster between 2009 and 2018 than growth rates observed between 1960 and 2009: According to Elizabeth GamilloFebruary 18, 2022 9:00 a.m.

Rising temperatures over Antarctica’s harsh landscape are causing two native plant species to flourish and spread across the continent. Between 2009 and 2019, plant cover has increased more than in the last 50 years combined and corresponds with rising air temperatures and declining fur seal populations, reports Phoebe Weston for the Guardian. The study published this week in Current Biology is the first to show the accelerated impacts of climate warming in polar ecosystems.

“Antarctica is acting as a canary in a coal mine,” Nicoletta Cannone, an ecologist at the University of Insubria and the study’s lead author, told Gizmodo’s Molly Taft.

Antarctic hair grass, Deschampsia Antarctica, and Antarctic pearlwort, Colobanthus quitensis, are the only two native flowering plant species on the southernmost continent. They can withstand the continent’s frigid temperature and photosynthesize at temperatures below zero while covered in snow, Cannone explained to Gizmodo.  

Researchers focused their observations on these plants on Signy Island and compared them to extensive records detailing plant growth recorded since the 1960s, Gizmodo reports. The team found that the plants are flourishing in a warmer climate. Antarctic pearlwort, a small plant with yellow blossoms, grew five times faster between 2009 and 2018 than growth rates observed between 1960 and 2009, per the Guardian. Hair grass, on the other hand, grew ten times more in the past decade than in other years.

Scientists previously thought that Antarctica was immune to global warming. However, studies have shown that the continent has warmed up three times faster than the rest of the world within the last three decades. The continent has also seen a record amount of ice loss. Between 2008 and 2015, ice loss increased by 36 billion gallons per year, according to Gizmodo.  

The team suspects the primary cause of the plants’ increasing growth is warming summer air. In the past decade, summer temperatures on Signy Island have increased between .36 Fahrenheit to .49 Fahrenheit each year with the exception of one cold spell recorded in 2012,the Guardian reports. In general, Signy Island’s mean annual average air temperature has increased by 1.8 degrees Fahrenheit between 1960 and 2018.

Other factors that may have contributed to the plant growth in Antarctica are dwindling fur seal populations, reports New Scientist’s Alex Wilkins. Fewer fur seals on the island mean fewer plants are trampled over, per the Guardian. But warmer temperatures seem to be the most evident link and could spell trouble for the fragile ecosystem.

An increase of native plant species can change the chemical makeup of the continent’s soils. This can change how organic matter decomposes and degrade the permafrost, per the Guardian. Higher temperatures may also pave the way for invasive species to outcompete native plants. 

“The study shows that further increases in populations of these plant species can be expected as Antarctica warms in future decades, leading to a greening of the region, but that there may also be increased risks to ecosystems associated with the establishment of alien plant species,” Kevin Newsham, a terrestrial ecologist not involved with the study tells the Guardian.

HISTORY: Man Adopts Orangutan’s Nature Of Using Tools To Break Stones

#AceHistoryReport – Feb.17: Orangutans instinctively use hammers to strike and sharp stones to cut, a study has found.

#AceHistoryDesk says NATURE & NURTURE according to the researchers, the findings suggest that two major prerequisites for the emergence of stone tool use — striking with stone hammers and recognising sharp stones as cutting tools — may have existed in our last common ancestor with orangutans, 13 million years ago.

Thursday 17 Feb 2022 8:10 am

Researchers tested tool making and use in two captive male orangutans that had not previously been trained or exposed to demonstrations of the activities.

Each animal at Kristiansand Zoo in Norway was provided with a concrete hammer, a stone, and two baited puzzle boxes.

The animals needed to cut through a rope or silicon skin in order to access a food reward.

The study found the orangutans spontaneously hit the hammer against the walls and floor of their enclosure, but neither directed strikes towards the stone to create a sharp tool.

In a second experiment, the orangutans were also given a human-made sharp flint flake, which one orangutan used to cut the silicon skin, solving the puzzle.

‘When presented with a human-made flake, a naive orangutan spontaneously used it as a cutting tool to open a puzzle box, providing proof of concept that cutting (or piercing) using sharp-edged tools is within orangutans’ spontaneous repertoire,’ said researchers.

Alba Motes-Rodrigo, at the University of Tubingen in Germany, and colleagues say this is the first demonstration of cutting behaviour in untrained orangutans.

In order to investigate if apes could learn the remaining steps from observing others, researchers showed three female orangutans at Twycross Zoo in the UK how to hit the stone to create a sharp flint flake.

After the demonstrations, one female went on to use the hammer to hit the stone, directing the blows towards the edge as demonstrated.

This study is the first to report spontaneous stone tool use without close direction in orangutans that have not been socialised by humans, researchers say.

The findings suggest that two prerequisites for the emergence of early lithic technologies – lithic percussion (the removal of sharp stones) and the recognition of sharp-edged stones as cutting tools – might be deeply rooted in the evolutionary past of humans.

ARCTIC: Giant Sponge Gardens Discovered Beneath Sea On Top Of Extinct Volcanoes

#AceNewsReport – Feb.10: Researchers have discovered the secret to survival of “massive” sponge gardens thriving on top of a ridge of extinct volcanoes beneath the ocean, 350 kilometres from the North Pole.

#AceNewsDesk says giant sponge gardens discovered on the peaks of extinct volcanoes under Arctic sea ice: It’s a region permanently covered in sea ice in one of the most oligotrophic seas on the planet. An oligotrophic sea is one generally devoid of plant life and very high in dissolved oxygen according to ABC (Science) News

But in a paper published today in Nature Communications, they reveal that the sponges survive by getting nutrients from dead sea life that once inhabited the seamounts, according to lead author Teresa Morganti from the Max Planck Institute for Marine Microbiology.

Though the scientists found the sponges a few years ago, they weren’t able to figure out how they were living in such a hostile environment.

“The extinct community was mostly composed of tubeworms and other polychaetes [bristle worms],” Dr Morganti said.

So how was there a community of animals living there before, and what happened to them?

The researchers concluded that there was an underwater seep of gases like sulfide and methane from the volcanoes, until around 2,000 to 3,000 years ago.

“The previous community … relied on the chemical compounds from the seepage as energy and food sources,” Dr Morganti said.

“Once the volcanoes’ activity ceased, [they] died out.”

But the sponges inhabiting the area today have a microbial symbiont — a micro-organism that can extract carbon and nitrogen from the bodies of the animals that once lived there.

In doing so, these microbial symbionts provide nutrients to the sponges, and the sponges in turn provide structure, and also further nutrients to their symbionts as they filter the passing water.

“Both benefit from each other,” Dr Morganti said.

The find is the most northerly sponge garden ever discovered, the scientists said.

It’s also the “densest sponge community found in the Boreal-Arctic regions”, according to Dr Morganti.

The seamounts consist of three extinct volcanic peaks, known collectively as the Langseth Ridge.

The ridge is about 125 kilometres long with the largest peak rising 2,500 metres off the seafloor to about 570 metres below the ocean surface.

The first sponge from the area was “casually” collected back in 2011, and a proper expedition of the seamount was launched in 2016.

That expedition discovered sponge gardens covering an area more than 35 kilometres long and  nearly 10 kilometres across at their widest point.

Solving the food supply mystery

But scientists then had to answer the question of how an area that should be virtually devoid of life was supporting such a rich diversity. 

“Our study here was focused on solving the mystery around the food source,” Dr Morganti said.

“It took quite a while because we tested so many different hypotheses and used very novel methods in dating and identifying the food web structure, and the symbionts and their functions.”

Along with the sponges, the researchers identified shrimp, starfish, and soft corals. They estimated around 60 species are inhabiting the seamounts in all.

But the physical conditions that have led to the formation of this unique environment are going to change quite dramatically.

The IPCC predicts that at 2 degrees Celsius of warming, the Arctic will experience ice-free summers around once every 10 years.

More sunlight penetrating the ocean could lead to an increase in the amount of food reaching the sponge gardens, Dr Morganti said.

“Such change might not harm these sponges themselves but rather favour the settlement of other species,” she said.

The researchers are calling for increased marine protection zones for the Arctic to be put in place before receding sea ice opens it up for further exploitation.

“The sea ice naturally protects environments from overfishing.”

“But when it recedes, it’s important to know which biodiversity hotspots are to be protected, especially from [bottom] trawling that is destructive for such [immobile] forms of life,” Dr Morganti said.
