Africa's two elephant species are declared endangered, one critically

Conservationists are calling for an urgent end to poaching.

Story at a glance

The International Union for Conservation of Nature now lists the African forest elephant as critically endangered and the African savanna elephant as endangered.

Both species have experienced sharp declines in their numbers due to an increase in poaching for ivory, as well as habitat 

Populations of the two species combined are estimated to be around 415,000.

Elephant populations across Africa are becoming increasingly threatened with extinction due to poaching and destruction of their habitat, according to a new assessment from conservation group the International Union for Conservation of Nature (IUCN).

The IUCN’s Red List of Threatened Species now lists the African forest elephant as critically endangered — the highest category before extinction in the wild — and the African savanna elephant as endangered due to the animals declining numbers. Both species were previously considered vulnerable, just one level down from the endangered designation.

The group said it’s the first time the African elephants were assessed as two separate species, following the emergence of new genetic evidence gathered over the past decade. Forest elephants are found in Central Africa’s tropical forests while savanna elephants roam the open grasslands and deserts in Sub-Saharan Africa.

According to the IUCN, both species have experienced sharp declines in their numbers due to an increase in poaching for ivory, as well as habitat loss. Populations of forest elephants dropped by more than 86 percent over more than three decades while savanna elephants have seen a 60 percent decline in their numbers over the last 50 years. Populations of the two species combined are estimated to be around 415,000.

“We must urgently put an end to poaching and ensure that sufficient suitable habitat for both forest and savanna elephants is conserved,” Bruno Oberle, IUCN director general, said in a statement.

“Several African countries have led the way in recent years, proving that we can reverse elephant declines, and we must work together to ensure their example can be followed,” Oberle said.

The conservation’s group Red List includes 134,425 species with 37,480 considered to be threatened with extinction.

 Indigenous shaman has a warning about the Amazon and all life on Earth

Davi Kopenawa is a messenger for our time.

The forest is alive. It can only die if the whites continue destroying it. If they do, rivers will disappear under the earth, the soil will crumble, the trees will wither, and the stones will melt in the heat. A desiccated earth will become empty and silent. The Xapiri spirits who came down from the mountains to play on their mirrors will flee far away. Their fathers, the shamans, will no longer be able to call them and to make them dance to protect us. They will be unable to push back the smoke of the epidemics that are devouring us. They will no longer be able to contain the evil spirits that will turn the forest into chaos. We will die one after the other, the white as much as us. All the shamans will finish by dying out. If none of them survive to hold on to it, the sky will fall.”                               

                                     Davi Kopenawa Yanomami Shaman

It is a most vital and perhaps the most urgent singular Indigenous voice Davi Kopenawa brings to the outside world in his book “The Falling Sky” published in 2010: it is the conscience of the rainforest itself unlike anything we have witnessed this century. It embodies the mind of the Amazon and narrates the journey into the rarefied, inner landscape of the shamanic world. Davi, called the Dalai Lama of the Rainforest, speaks words composed of myth, of thunder and lightning and spirit beings honored since time immemorial, whose chorus is dwindling in light of what remains of the largest rainforest on Earth. Narrated by a Yanomami shaman it is a revelation of an Indigenous people facing the onslaught of the dominant society felling and desecrating their forest home. Davi wants white people and foreigners of the world to know what is happening to the forest and his people the Yanomami of southern Venezuela and Northern Brazil, a tribe of about 35,000, and what will ultimately happen to us all if the life force of the Amazon is lost.

About 30 years ago, miners killed 16 of their tribe, including a baby in Haximu village. Five miners were guilty of genocide. More recently miners from northern Brazil were confronted by two Yanomami, who died in the encounter. 2019 finally launched the global campaign to expel 20,000 gold miners who are illegally prospecting on Yanomami land. The future of the Yanomami may very well rest on how this epic struggle is resolved.

Thomas Lovejoy, who has been teaching climate change biology for 30 years and introduced the term biological diversity, along with other ecologists have long warned that mining, palm plantations, and cattle could destroy the hydrological cycle of the Amazon. Some even believe the time is now to monetize the forest in a green economy, which includes aquaculture, medical and plant knowledge and a resources base that actually looks to make the Amazon invaluable for the future. The time is now to put a price on what can renewably be cultivated from biodiversity’s “greatest showroom” the “living library” of the Amazon according to Lovejoy.

The Swiss firm Re estimates that half of the global GDP of $42 trillion depends on resilient biodiversity. Robert Costanza, an ecological economist, says the ecosystem yearly yields a return of 100 to 1. Some like Timothy Weiskel, formerly at the Harvard Divinity School, are outraged by the notion of affixing a price tag or cost benefit analysis to ecosystems. But Costanza believes it is a way of seeing nature in a pragmatic way, by putting numbers on the overall destruction and loss that results in biospheric damage. Acting on this will be the hard part but perhaps a key way to persuade policymakers to see the actual cost of exploitation. Planetary accounting writ very large.

Costanza notes that the biosphere can yearly be valued at 33 trillion dollars not as mere commodity but in terms of renewable value. The value for humanity and life on Earth may seem counterintuitive, because it is ultimately priceless, but if one attaches a monetary value to the resource base of let’s say a forest, then it becomes more tangible. One of the challenges we face is to calculate the metrics of what ecosystems are worth in monetary terms. It would be mandated by government in everything from bond markets to investment banking so that nature, our life support system, is included in the decision-making financial system. So far nature has been left out of the economic balance sheet. If humanity wishes to survive, some say, we can no longer allow this separation.

As for the president of Brazil, for the crimes he has encouraged in burning the Amazon, Jair Bolsonaro’s possible trial looms at the Hague. The world might finally take heed of punishing those who have allowed almost 17 percent of the Amazon to go up in smoke. Just 20-25 percent loss, experts say, would be the point of no return for the greatest rainforest on Earth. It would turn to savanna and one of the most irreplaceable carbon sinks on Earth will be no more. The Amazon may already have become a net emitter of carbon, at humanity’s immense peril. The vastest jungle on Earth may have already reached the tipping point. But Lovejoy also underscores that despite increasing droughts in the Amazon, it is still possible to reforest some of the destruction that has been imposed on the jungle and bring back some “margin of safety against dieback.” He encourages all the Amazon countries to come together and create an integrated management plan for the future of the Amazon. But they have to do it soon. The hydroelectric dams and the roads that have sliced through the jungle since the 1970s have fragmented the Amazon. It is very late in the game but some are finally coming to understand the immense importance of the hydrological cycle of the largest jungle on the planet. There is simply less moisture being created in the Amazon. As forests burn around the world, the implications for the world are beyond enormous.

Davi’s understanding of the rainforest, issues from an ancient and cellular order of being, the other worlds he has penetrated beyond the surface and outer reality of what we perceive. Beyond the digital surface of our super specialized technological society, is a wide web of inner vision, the larger fabric of life that spans the animate and the perceptual. Very few have access to this inner world. In this time of gold diggers and cattle rustlers it is time the world listened to the first peoples of the world, before their world and ours disappears.

To read Davi’s book is to listen to a cosmological missive to the world, as close to the heart of Earth’s mind as is possible. Years ago not far from the Yanomami territory we had just heard of Davi’s people but little else. We had occasion to see, before the great tumult in Venezuela, the majestic Angel Falls, the tallest on Earth at 970 meters, its sheer height, like the tresses of a goddess dissolving into mist from the impossible height of the Tepui formations made of Precambrian sandstone rocks. We only heard hints of a people on the far frontier of Venezuela and Brazil, people who as Davi describes, had dreams such as we the “civilized people” did not have.

In fact, Davi acknowledges that white people do not think very far ahead. The Yanomami’s world is directed by paths in the jungle rather than merchandise. We live on different planets. “White people think we are ignorant because we don’t possess paper on which to write our words. What lies. We will only really become ignorant only when we no longer have shamans. It is from the yakoana (plant) and the spirits of the forest that we learn. We can see lands very far away, we can enter the body of the sky or descend into the subterranean world,” he says. The visions of supervening forces and energies that tie life together as one web is not something most of us are privy to. Without entering or having the consciousness or the images of the beings of the first time, we cannot begin to understand what Davi has seen or alludes to. It is very reminiscent of what the Aboriginal elders referred to as the Dreamtime and the Creator Beings, wavelengths of formative primal energies we cannot really fathom because it is a psychodynamic and sensual reality we long ago lost touch with in the modern world and energies that all our technological prowess cannot see or feel.

Some of the “witches,” healers, wisdom keepers, the messengers of nature in Europe had a connection with the planet. And what did we did do to them? Many we burned at the stake because they represented another understanding entirely, another way of seeing born of the much older pagan world and not the world view of the Church. Today we are burning the world for trinkets, for the lackluster realm of the modern economic system, for vast soy bean plantations and cattle and mining operations. It is among the greatest follies of our civilization and literally costing humanity the lifeline to life itself. In Davi’s eyes, in his spiritual sight especially, the gambling machine of the business world is built on quicksand. Our civilization is burning itself to the ground. It is not just his peoples who are disappearing. It is also us.

Omama, the primal energy, is still the stuff of science fiction even for most specialists and those frequencies of consciousness we attempt to see with instruments cannot penetrate the veil of the shaman’s inner vision. Perhaps the oldest essential way of communing with nature, shamanism is a “sight” we are on the verge of losing as a species. What we are experiencing worldwide is partially due to the loss of this larger vision that a few elders still encompass. They live in a manifold world of many colors, songs and dimensions while we inhabit the world of the economic sphere and its short term returns. The two live on different planets. And worldwide, the elders are dying of the virus. What indeed will remain of their vision?

Davi is worried that the younger generation will not only lose the forest, but also that they will be beholden to the machine and motor vehicles, having to trace words on paper because our spirits are forgetful and will no longer remember our original instructions, which is to take care of the world.

Even if these realities seem arcane and primal beyond the highly specialized and fragmented modern industrial reality, the Yanomami, whose men are warriors and who can be brutal have lived in the forests for thousands of years without overwhelming their habitat. The recent invasion of 20,000 gold miners in the Orinoco basin is an affront to their way of life and is extinguishing a society much older than civilization. In light of the microbes our species has to confront and the threat of future pandemics, which could arise from the tropics, Davi’s words speak of a covenant with the very fabric of cellular memory embedded in the plants and the radical light that suffuses Creation. The extraordinary death toll Brazilians have had to endure in such cities as Manaus, in the middle of the Amazon, gives enormous relevance to Davi’s words. If we are still arguing over what we must do at the end of this decade, it will be too late.

Davi exclaims, “With these words, I want to simply warn the white man that the bad things they extract from the earth will not make them rich very long! The value of our dead will be very high and they will certainly not be able to compensate us with their paper skins (their contracts). There is no money that can buy the forest, the hills and the rivers. Their money will be worth nothing…They must understand this. The ghosts of the old shamans and their evil spirits have already started to take vengeance on far way lands by provoking droughts and endless floods. It is why, if the whites do not make us all die, we will continue to call on the spirits to consolidate the forest and prevent the sky from falling.

“The forest is intelligent and has thought identical to ours. I listen to the words of my spirits who ask with anger, ‘Why are the whites so hostile? Why do they want us to die? What do they have against us that, we have done nothing to them. Is it only because we are other peoples, the peoples of the jungle? Do not worry, they will kill you, maybe, but they will not long stay unharmed by their destruction!’ It is so. We are saddened by the idea of disappearing. But our thoughts are quieted by the thought that the spirits are innumerable and will never die.

“If we disappear, the whites will not live long after us. Even if there are many of them, they are not made of strong, any more than us. Their life breath is as short as ours. They can suppress us today, but later, when they will want to move in places where we once lived, they will be devoured in their turn, by all sorts of bad spirits. We will see if they are as powerful as they think! We will plunge them in darkness and storms. We will break the sky and its fall will sweep them away. Be finally warned! Stop pillaging our earth, because the smoke of your epidemic will finish us all off and when you build your towns on our forgotten vestiges in the forest, you will destroy yourselves. The spirits of the shamans you have killed will avenge themselves.

“If you destroy the forest, the sky will break and it will fall on the earth. The whites are not afraid, as we are, to be crushed by the falling sky. But one day, they will fear it as much as we do. The shamans know what bad things menace human beings. There is only one sky, and one has to worry because if it becomes sick, everything will be finished.”

Since a child, Davi has been warned of foreigners and missionaries who considered the Yanomani primitive heathens, and has been wary of the white man’s God. “Maybe God will punish me and will cause me to die. It doesn’t matter, I’m not white. I do not want to know anything about him. He has no friendship with the inhabitants of the forest. He doesn’t cure our children. He doesn’t defend our earth against gold miners and ranchers. It is not he who makes us happy. His words only know threats and fear. Even today, the people of God haven’t stopped terrifying me. When I have the occasion to meet them they tell me - Davi, your thinking is obscure. You are possessed by Satan. If you keep listening to his words you will burn in the fire pit. Stop answering the spirts so your thoughts can blossom anew with the words of God. It he who will really protect you.”

The God of foreigners have been setting the Amazon on fire for years. Everything the forest has taught the Yanomami and countless other tribes for generations is under threat ecologically and also spiritually due to the rampage of the pandemic, which is killing off elders all over the world. Their knowledge translates to perhaps 25,000 years of experiential wisdom that will never be brought back if lost. In this time of climate change their understanding of the planetary “mind” is among the most sophisticated on Earth. Davi has heard of original sin from those who preach the gospel and yet what has happened, is happening and could continue to ravage the forest, is the greatest scourge of our time. Davi defends himself against the foreign God by saying, “We are not bad. We are simply not Whites. We are such as our ancestors have always been. For us all the words of the White Man are in vain. God must be lazy because he makes no effort to cure us, even when we are in agony. We are dying without them caring in the least.”

With the word in upheaval it is time, it might seem, to listen to those who have not destroyed their world. We are beholden to “sad leaves” as Davi calls money. But Davi has known that whatever befalls his people will also befall modern civilization. This is the decade of reckoning. Either we pull back from the brink or the sky will crumble and so will the Earth. In listening to the shamans and the elders of the jungle, we might learn something about life on Earth, that might actually save us.

As Davi says, “If there are no longer any shamans in the forests, the white man will consume himself before becoming blind. He will end by suffocating, reduced to a state of a ghost, and will fall to pieces. Then we will all be carried into the darkness of the subterranean world, the Whites as well as us. There is only one sky and one has to take care of it, because if it becomes sick, everything will be finished.”

Shipping container crisis could spark another toilet paper shortage

BY SARAH POLUS - 03/25/21 

The world may face another toilet paper shortage similar to the one experienced at onset of the COVID-19 pandemic due to high demand for shipping containers, Bloomberg reports.

Suzano SA — the world's largest producer of wood pulp, needed to make toilet paper — is now warning that the demand for shipping containers could delay shipments to producers.

As the container crisis continues, the Brazil-based company is finding it harder to secure shipping containers to transport wood pulp.

The company's Chief Executive Officer Walter Schalka said if the issue worsens, a worldwide toilet paper shortage could be inevitable. The company has already had to push back shipments originally scheduled for March into April, according to Bloomberg.

The outlet reports that the worldwide shipping crisis, which has been going on for months, stems from increased demand from China. The shortage has trickled down through the global economy, already impacting supplies of other products, including coffee and cheese.

In the spring of 2020 as the pandemic hit the U.S., retailers across the country experienced shortages of products including toilet paper as panic over supplies caused people to stockpile household necessities as they entered into quarantine.

Last April, Walmart CEO Doug McMillon told NBC News his company sold enough toilet paper in five days for every American to have a roll.

Regulator: Evidence suggests Texas 'absolutely' didn't follow recommendations to winterize power equipment

The CEO of the North American Electric Reliability Corporation (NERC) told Congress on Wednesday that evidence shows Texas “absolutely” did not follow recommendations by the organization and federal regulators in 2011 to winterize their equipment.

During a Wednesday House hearing on the failure of Texas’s electric grid during last month's winter storm, Rep. Diana DeGette (D-Colo.) asked NERC CEO James Robb whether Texas followed the organization’s recommendations.

“The inquiry will affirm this, but the evidence would suggest absolutely not,” Robb responded, referring to an ongoing probe that the group is conducting alongside the Federal Energy Regulatory Commission (FERC).


The winter storm in Texas led to days-long power outages and was linked to several deaths.

After blackouts following a cold snap in 2011, FERC and NERC put together a report that said that many power-generating companies had “failed to adequately prepare for winter.”

The report recommended that “all entities responsible for the reliability of the bulk power system in the Southwest prepare for the winter season with the same sense of urgency and priority as they prepare for the summer peak season.”

Later in Wednesday's hearing, Robb raised concerns about both the lack of legal changes and enforcement in Texas.

“The report that we put out in 2011 calls for very clear freeze protection on the generating plants,” he said. “What I understand Texas did was to put in place legislation that required weatherization but not to a specific level, and it was not an aggressively enforced standard.”

During the hearing, the CEO of the Electric Reliability Council of Texas (ERCOT), which manages the grid's power flow, testified that there were points during the blackouts when natural gas, wind, coal, solar and nuclear power each went down.


“We did see periods of time where each one of those ... tripped offline,” said Bill Magness.

He also said that ERCOT should have had better communication with the public.

“Those times when we saw how large this would be and began to understand how long it would last, the communications around that I think we certainly could have done better,” Magness said.

Houston Mayor Sylvester Turner (D) raised similar concerns about communication, saying that his city's residents were told that rolling blackouts would only last for an hour or two, instead of several days.

“We were told by our transmission distribution company to expect rolling blackouts anywhere from 1 hour to 2 hours maximum,” Turner said. “I was on the phone asking my transmission distribution company, what is the problem ... they were not prepared, and we were not forewarned.”
A Canadian mining company called Musk spiked this week after buying the rights to the 'Elon' lithium property

Shares of Musk Metals popped this week following the Canadian miner's deal to buy a lithium property called "Elon".

Musk Metals says the deal arrives as the "shift to electric vehicles" drives demand for battery metals and materials.

The company plans to acquire 3 million shares of Tonto Investments for the deal.

Shares of Canadian miner Musk Metals pulled back Wednesday after a more than 50% surge following the company's deal to acquire a prospective lithium property named "Elon".

Musk Metals' press release on Tuesday outlining its deal didn't make a direct reference to Elon Musk, the famed CEO of electric car maker Tesla and billionaire bitcoin enthusiast.

The miner said it reached an "arm's length" share-purchase agreement with Tonto Investments to acquire a 100% interest in the "Elon" property in Quebec, Canada. Musk Metals plans to acquire all 3 million of Tonto's issued and outstanding shares, subject to regulatory approval and other customary conditions.

Musk Metals' Canada-listed shares fell by 14% on Wednesday after soaring 56% to C$0.14 ($0.11) on Tuesday. Its US-listed shares that are traded over the counter also fell during Wednesday's session.

"Fueled by the recent shift to electric vehicles, demand for battery metals and materials has skyrocketed. Musk Metals has diversified its portfolio of highly prospective exploration projects to include the "ELON" lithium property as the company strives to maximize shareholder value by participating in this red-hot space," said Nader Vatanchi, chief executive and director at Musk Metals, in a statement.

The company said the Elon lithium property is located in an active lithium exploration and mining area and spans over 245 hectares in the La Corne and Fiedmont townships of Quebec.

Janey becomes 1st woman, person of colour to be Boston mayor

Boston has a new mayor in Kim Janey, who became the city’s first female and first person of colour to take the office Monday

Marty Walsh resigned Monday evening to become President Joe Biden’s labour secretary. The Boston City Council President Janey, who is Black, stepped into the role of acting mayor and is scheduled to have a ceremonial swearing in Wednesday.

Walsh, the latest in a long line of largely Irish-American Boston mayors stretching back the better part of a century — with one notable Italian-American exception — said he welcomed the change.

“History will be made tonight," Walsh said earlier in the evening. "We're an extremely diverse city from different backgrounds and different nationalities and different skin colours. I think it's a good thing for our city. I think it's a great thing for our city.”

Janey took to Twitter to wish Walsh well following his confirmation by the U.S. Senate.

“Congratulations on your confirmation, Secretary Walsh. You are a proud son of Dorchester who will bring our city with you,” she tweeted. “The working people of America will benefit greatly from your passion.”

“Now, we look ahead to a new day — a new chapter — in Boston’s history,” Janey, a fellow Democrat, added.

Walsh said for the past two months he's had regular meetings and conversations with Janey. The two have also held extensive planning sessions, he said.

"Together the council president and myself and our teams have worked diligently to ensure a smooth transition,” he said.

By any typical political stopwatch, Janey's rise has been lightning quick. She was first sworn in as a city councillor just three years ago.

Although Janey, 55, is holding the office only on an interim basis, she's widely seen as hailing a new chapter in Boston’s political history.

Those actively seeking the office include three women of colour — current city councillors Michelle Wu, Andrea Campbell and Annissa Essaibi George. John Barros, who is of Cape Verdean descent and state Rep. Jon Santiago are also running. Barros served as chief of economic development under Walsh.

Janey has a long history of activism in Boston, with deep roots in Roxbury, the heart of the city’s Black community.

He grandfather, Daniel Benjamin Janey, was a member of Twelfth Baptist Church where Dr. Martin Luther King Jr. worshipped while attending Boston University. Her father was one of only eight Black students to graduate from the city’s prestigious Boston Latin School in 1964.

While spending time in her great grandmother’s home in the city’s South End neighbourhood, Janey was also exposed to the city's political culture as she watched a neighbour — Black community activist and former state Rep. Mel King — launch a bid for mayor in 1983, losing to Ray Flynn, an Irish-American city councillor.

During the second phase of Boston’s tumultuous school desegregation era, Janey would recall the rocks and racial slurs she said were hurled at her as an 11-year-old girl riding the bus to the largely white neighbourhood of Charlestown. She would later take part in a program that allowed her to attend school outside the city.

Janey began her career in advocacy with Massachusetts Advocates for Children, pushing for policy changes she said were aimed at ensuring equity and excellence for public school students in Boston.

In 2017, she won a 13-candidate race and became the first woman to represent her district, which includes most of Roxbury, parts of the South End, Dorchester, and Fenway areas of the city.

Although she hasn’t said yet if she’ll run for mayor in the fall, there is precedent for an interim mayor using the temporary post as a stepping stone to winning the seat outright.

When former Mayor Raymond Flynn stepped down to become President Bill Clinton’s ambassador to the Vatican, then-city council president Thomas Menino stepped in as interim mayor in July 1993, won the mayoral election later that year, and ended up serving in the office longer than anyone in the city’s history.

'Dancing' fish could be key to ridding salmon farms of parasites

Benjamin Whittaker, Postdoctoral Fellow, Department of Integrative Biology, University of Guelph and Elizabeth Boulding, Professor, Integrative Biology, University of Guelph 

Biologists study the social behaviour of fish through their communication, which includes grunts, clicks and coordinated flatulence. Cleaner fish feed on the parasites that live on the skin of many different species of fish, known as clients.© (Shutterstock) A bluestreak cleaner wrasse in an aquarium.

Some species of tropical cleaner fish are skilled communicators and display elaborate dances. New research focusing on the social behaviour of cold-water cleaner fish aims to help salmon farmers control parasitic sea-lice in aquaculture.

Dancing tropical fish

Diving among the coral reefs of the Indo-Pacific — the geographic region comprising the Indian Ocean and the west Pacific Ocean — you might see a bluestreak cleaner wrasse, which is a highly intelligent species and perhaps the first fish to show self-awareness. This wrasse relies on cleaning parasites from clients to find the majority of its diet.

© (Shutterstock) Bluestreak cleaner wrasses communicate with their client fish in order to provide a mutually beneficial service.

Attracting new clients and getting them to cooperate while removing parasites can be a difficult task. To make the job easier, bluestreak cleaner wrasse perform a complex dance and massage clients with their fins. This display relaxes the client, allowing the cleaner to approach and closely inspect its skin for parasites.

This is an example of mutualism because both parties benefit from interaction: the cleaner gets a meal and the client is rid of parasites. For decades, biologists have studied the behaviour of bluestreak cleaner wrasse to research mutualism, however, there are many other species of cleaner fish which are yet to be studied.

Cold-water communication


Investigating whether cold-water cleaner fish communicate with clients is particularly important for the salmon aquaculture business. Sea-lice are a huge economic, ecological and ethical problem for salmon farmers, and controlling louse populations is a big challenge.

Stocking cold-water cleaner fish in sea-farms may help reduce parasite numbers on the salmon. However it is unknown whether cold-water cleaner fish dance for their clients, or whether these species can communicate at all, which would affect how good they are at removing sea-lice from salmon.

To investigate this potential, our research team at the University of Guelph looked at how cunner wrasse communicated with salmon.

Strike a pose

We filmed cunner wrasse, a native cleaner fish from eastern Canada, swimming inside aquariums with salmon to see how the two species interact. At first, we were disappointed not to see any underwater dancing, but then a particularly large cunner swam out in front of the salmon and made an unusual pose.

The cunner pointed down towards the floor, spread its fins open wide, and hung suspended in the water for a few brief moments before swimming away. Several minutes later it returned to strike another pose, this time for longer, and moving slowly around the salmon.

Our video analysis showed that cunners posed more frequently towards salmon that had sea-lice on their skin, compared to salmon free of parasites. Cunners that posed more frequently would get closer to salmon, and also spend longer time periods visually inspecting the salmon.

These results imply that cunner wrasse pose towards salmon as a form of communication, which helps the cunner gain access to lice on the salmon’s skin.

Poser for mutualism


Cunner wrasse didn’t perform the complex ballet of their tropical counterpart, however, they displayed a series of highly exaggerated poses that was reminiscent of the voguing trend of the late 1980s.

This simpler dance style might reflect the fact that cunners can find alternate food sources, and don’t rely on eating parasites as much as bluestreak cleaner wrasse. Studying more diverse species of cleaner fish might give more insight on the biology of mutualism and fish communication.

It’s important to note than not every cunner showed posing behaviour and some individuals would hide from salmon, whereas others embraced the spotlight. Measuring differences in posing behaviours could help farmers choose the best cleaners to use for sea-lice control. It could also help identify factors that influence communication between cunner wrasse and salmon, like genetics and environment.

Facebook, Twitter must do more to stop COVID-19 anti-vaxxers, U.S. states say

(Reuters) - Attorneys general for 12 U.S. states on Wednesday accused Facebook Inc and Twitter Inc of doing too little to stop people from using their platforms to spread false information that coronavirus vaccines are unsafe.

In a letter to Facebook Chief Executive Mark Zuckerberg and Twitter CEO Jack Dorsey, the Democratic attorneys general said "anti-vaxxers" lacking medical expertise and often motivated by financial gain have used the platforms to downplay the danger of COVID-19 and exaggerate the risks of vaccination.

They called on both companies to enforce their own community guidelines by removing or flagging vaccine misinformation.

The letter said anti-vaxxers control 65% of public anti-vaccine content on Facebook, Instagram and Twitter, and have more than 59 million followers on those platforms and Google's YouTube.

It also said some misinformation targets Blacks and other communities of color where vaccination rates are lagging.

"Given anti-vaxxers' reliance on your platforms, you are uniquely positioned to prevent the spread of misinformation about coronavirus vaccines that poses a direct threat to the health and safety of millions of Americans in our states and that will prolong our road to recovery," the letter said.

Facebook spokeswoman Dani Lever said the company has removed millions of pieces of COVID-19 and vaccine misinformation, and tries to combat "vaccine hesitancy" by regularly directing users to reliable information from health authorities.

Twitter said it has removed more than 22,400 tweets in connection with its policy toward COVID-19 posts, and prioritizes removing content that could cause "real-world" harm.

1 report, 4 theories: Scientists mull clues on virus' origin


GENEVA — A team of international and Chinese scientists is poised to report on its joint search for the origins of the coronavirus that sparked a pandemic after it was first detected in China over a year ago — with four theories being considered, and one the clear frontrunner, according to experts.

The lengthy report is being published after months of wrangling, notably between U.S. and Chinese governments, over how the outbreak emerged, while scientists try to keep their focus on a so-far fruitless search for the origin of a microbe that has killed over 2.7 million people and stifled economies worldwide.

It wasn’t immediately clear when the report will be released after its publication was delayed earlier this month. By many accounts, the report could offer few concrete answers, and may raise further questions.

It will offer a first glance in writing from 10 international epidemiologists, data scientists, veterinary, lab and food safety experts who visited China and the city of Wuhan — where a market was seen as the initial epicenter — earlier this year to work with Chinese counterparts who pulled up the bulk of early data.

Critics have raised questions about the objectivity of the team, insisting that China's government had a pivotal say over its composition. Defenders of the World Health Organization, which assembled the team, say it can't simply parachute in experts to tell a country what to do — let alone one as powerful as China.

“I expect that this report will only be a first step into investigating the origins of the virus and that the WHO secretariat will probably say this," said Matthew Kavanagh, director of Georgetown University's Global Health Policy and Governance Initiative at the O’Neill Institute. “And I expect some to criticize this as insufficient. I think it is key to keep in mind that WHO has very limited powers."

The Wuhan trip is billed as Phase 1 in a vast undertaking to flesh out the origins of the virus.

The WHO has bristled at depictions of the mission as an "investigation" — saying that smacks of an invasive forensic probe that wasn't called for under the resolution adopted unanimously by the agency's member states in May that paved the way for the collaboration. The WHO and China later ironed out the ground rules.

Team member Vladimir Dedkov, an epidemiologist and deputy director of research at the St. Petersburg Pasteur Institute in Russia, summarized the four main leads first laid out at a marathon news conference in China last month about the suspected origins of the first infection in humans. They were, in order of likelihood: from a bat through an intermediary animal; straight from a bat; via contaminated frozen food products; from a leak from a laboratory like the Wuhan Institute of Virology.

Officials in China, as well as Chinese team leader Liang Wannian, have promoted the third theory — the cold-chain one — while the U.S. administration under President Donald Trump played up the fourth one, of the lab leak. But Dedkov said those two hypothesis were far down the list of likely sources.

He suggested frozen products on which the virus was found were most likely contaminated by infected people. An infected person also likely brought and spread the virus at the Wuhan market associated with the outbreak, where some of the contaminated products were later found.

“In general, all the conditions for the spread of infection were present at this market,” Dedkov said in an interview. “Therefore, most likely, there was a mass infection of people who were connected by location.”

“At this point, there are no facts suggesting that there was a leak" from a lab, Dedkov said. “If suddenly scientific facts appear from somewhere, then accordingly, the priority of the version will change. But, at this particular moment, no.”

Suspicions about political meddling have dogged the mission, and the international team leader — the WHO's Peter Ben Embarek — acknowledged in interviews last week that unspecified “pressures” might weigh on its members. Liang, in a Chinese newspaper interview, also bemoaned political pressure on the team.

Delays in deploying the international team to China, repeated slippage in the timing of publication of the report, and rejiggering of the plans for it — an initial summary of findings was jettisoned as an idea — have only fanned speculation that the scientists have been steered by political authorities or others.

“The last understanding we had was that it is expected to come out this week — we'll have to see if that actually happens,” the U.S. charge d'affaires in Geneva, Mark Cassayre, said on Wednesday. “We have a clear understanding that other studies will be required.”

He said the U.S. was hopeful the report would be a “real step forward for the world understanding the origins of the virus, so that we can better prepare for future pandemics. That's really what this is about.”

The WHO leadership, including Director-General Tedros Adhanom Ghebreyesus, repeatedly praised the Chinese government’s early response to the outbreak, though recordings of private meetings obtained by The Associated Press exposed how top WHO officials were frustrated at China’s lack of co-operation.

The international team was wholly reliant on data collected by Chinese scientists after the outbreak surfaced, and Dedkov called the visit to Wuhan an “analytical trip, mainly for the purpose of retrospective analysis in the sense that we studied only those facts that were obtained earlier.”

“We did not collect any samples ourselves, we didn’t carry out any laboratory studies there, we just analyzed what we were being shown," he said. If some data had not been collected, it wasn’t because the Chinese wanted to conceal something, he added.

The team’s visit was politically sensitive for China — which is concerned about any allegations it didn’t handle the initial outbreak properly. Shortly after the outbreak, the Chinese government detained some Chinese doctors who sought to raise the alarm.

The report, which Ben Embarek said last week took up about 280 pages, is set to lay out recommendations and lay the groundwork for next steps — such as whether the team, or others, get new access to China for further analysis. Ultimately, the aim is to find clues to help prevent another such pandemic in the future.

Georgetown’s Kavanagh said he hasn’t seen the report — but has suspicions about what it will say.

“Based on what we have heard so far I expect that the report will likely lend some credence to a link between wildlife farming and COVID-19, but without full evidence about exactly how the move from animals into humans might have occurred,” he said.

Dedkov said planning of “real-time research” is next, but noted there’s no guarantee future trips will find all the answers.

“But one can try," he added. "Of course, if the source of the origin of the virus is found, it will help answer many questions and, in general, will dissipate this unnecessary political tension around the virus."

Colombian town uses discipline, speakers to stay virus-free

3/23/2021

CAMPOHERMOSO, Colombia — When customers enter his hardware store Nelson Avila asks them to wear a mask and wash their hands. He sprays alcohol over the bills and coins they give him before putting them in the till.

Avila's shop is in Campohermoso, a town of 3,000 people in Boyaca state in the mountains of central Colombia that has no reported cases of the coronavirus. According to the Health Ministry, Campohermoso county - which consists of the town and surrounding farms and villages - is one of just two counties in the country that are COVID-19-free. Colombia has more than 1,100 counties.

“Those bills can carry the virus” said Avila, 49, as he disinfects a wad of wrinkled Colombian pesos. “They go from hand to hand, so we have to be careful.”

Officials and locals say the town has been able to keep the virus away thanks to the disciplined behaviour of its residents and constant campaigns urging people to social distance and wear masks.

The town’s remote location ringed by mountains, far from major roads, has also helped it to stay coronavirus-free. It has just seven streets and six avenues laid out in a neat grid. It is nestled at the bottom of a green valley, 3300 feet (about 1,000 metres) above sea level.

“Campohermosos has a low population density and little contact with big cities,” said Jairo Mauricio Santoyo, the health secretary for Boyaca state.

Given that Colombia, with a population of about 50 million people, has reported more than 2.3 million confirmed cases of the coronavirus, many consider the lack of infections here a small miracle.

During the first decade of this century, Campohermoso was affected by fighting between paramilitary groups and leftist rebels, says the town’s mayor, Jaime Rodríguez. The coffee-growing area has been peaceful for more than a decade but it is seldom visited by outsiders.

Rodríguez says communication has been crucial in keeping the pandemic away from Campohermoso. Messages about the virus and how to prevent it are broadcast three times a day on speakers perched on the town’s lampposts.

The local radio station also broadcasts daily shows that talk about prevention. To ensure everyone gets the message, the mayor’s office distributed 1,000 radios to farmers who live in Campohermoso's rural areas.

“The whole town has come together” Rodríguez said. “The police, the health centre, church personnel and the mayor’s office all go on the radio station to talk about the virus.”

Rodríguez said his message to townsfolk has been simple: “Its’ up to every family to stop it.”

He has also tried to lead by example. The mayor says he began to feel ill during a recent visit to Bogota, where he tested positive for the virus. He did not return to Campohermoso until he tested negative.

“We’ve put 60 families in town in quarantine because they showed some symptoms,” Rodríguez said. “But all of them have tested negative.”

Businesses are now open in Campohermoso and only allow customers wearing masks. The town has not banned visitors from other parts of the country but those who arrive and wish to stay have been asked to quarantine in a relative’s home, and receive a daily call from the local nurse.

Campohermoso’s only school is running at half of its usual capacity. Students have been divided by shifts and attend school every other day.

And in the largely Roman Catholic town, the local priest has also gotten involved in prevention efforts.

“We pray to Saint Roch, who is our patron saint and the protector of the sick,” says Father Camilo Monroy, who has also gone on radio to talk about ways to prevent the spread of the virus.

The only other town in Colombia that is reportedly coronavirus-free is San Juanito, which is also located in a remote valley in the Andes mountains.

Officials consider the two cases striking because the virus has even appeared in Amazon jungle villages that can only be reached by boat or small plane.

Campohermoso has vaccinated 80 people so far, most of them senior citizens over the age of 80.

Now the coronavirus-free county is waiting for more shots from Colombia’s central government.
