Exclusive: Philippines rejects US aid amid tensions in South China Sea – military chief


MANILA, July 5 (Reuters) – The Philippines has rejected a U.S. offer to assist with military operations in the South China Sea, the country’s military chief said, after a dispute with China over a mission to resupply Filipino troops in the disputed maritime region.

Tensions in the disputed waterway spilled over into violence last year, with a Filipino sailor losing a finger in a June 17 clash that Manila described as a “deliberate high-speed ramming” by the Chinese coast guard.

Armed forces chief General Romeo Broner told Reuters late on Thursday that treaty ally the United States has offered support but Manila prefers to conduct the operation on its own.

He said, “Yes, absolutely, they are offering help and they have asked us how they can help us.”

“We try to consider all the possible options we have before asking for help.”

Manila and Washington are tied to each other. 1951-Mutual Defense Treaty (MDT), A military agreement that can be used in case of armed attacks on Philippine forces, public vessels or aircraft in the South China Sea.

Confrontation between the Philippines and China in Asia’s most disputed waters has increased over the past year, as Beijing has asserted its claim to the waterway and Manila has continued missions to deliver supplies to troops staying on a rusty, old warship docked off the disputed coast.

Some observers, including former deputy US national security adviser Matt Pottinger, have called for direct US naval support for resupply missions.

But Philippines National Security Adviser Eduardo Ano said the Philippines wants it to be a “purely Philippine operation.”

“This is our legitimate national interest, so we see no reason for them (the US) to get involved,” Ano told Reuters.

Ano last month discussed with his US counterpart Jake Sullivan their shared concerns over China’s growing assertiveness. “Dangerous and escalating action”He said that MDT is still far from being implemented.

“We (the Philippines and China) have agreed that there will be some easing of tensions, but we will insist on our rights, we will not compromise our national interests, and we will continue to fight and claim what is ours,” Ano said.

None of the officials said what support the United States had offered.

Greg Poling, a South China Sea expert at Washington’s Center for Strategic and International Studies think tank, told Reuters he believed the U.S. was prepared to assist the Navy in a mission to resupply the stranded ship. He said Washington had already provided some limited assistance.

Poling reported that last year a Philippine official said Manila was consulting with the US Army Corps of Engineers on how to stabilize the BRP Sierra Madre, which is anchored on the disputed Second Thomas Shoal, while US aircraft have been filmed conducting surveillance over the ship on multiple occasions.

The Hague-based Permanent Court of Arbitration ruled in 2016 that Beijing’s expansive claim to the South China Sea through the nine-dash line had no basis under international law, but that did not stop China from becoming more aggressive in the waterway, which it rejected.

It has deployed coast guard ships to patrol those areas, worrying the Philippines, rival Southeast Asian claimants and other countries active in the South China Sea, including the United States, which is worried about China’s growing military power and territorial ambitions.

Army chief Broner said the offer of support made by the US in discussions held at his level was not a direct reaction to the June 17 incident but rather a reflection of the enduring military alliance between the two countries.

“This offer has actually been available to us for a long time because we’re treaty partners, and not just because of this incident,” Bronner said.

“But we haven’t asked them yet because we have to rely on ourselves first, as per our president’s order.”

The Pentagon did not immediately respond to a request for comment. Thursday was a federal holiday in Washington to mark the United States’ Independence Day.

While China claims almost all of the South China Sea, a major shipping route through which about $3 trillion in trade passes each year, Vietnam, Taiwan, Malaysia and Brunei also claim parts of it.

By 0600 GMT, the centre-left Labor Party appeared to be on course to win 410 of parliament’s 650 seats, beating exit poll forecasts of winning 410, a stunning reversal from five years ago, when it suffered its worst showing since 1935.

The result will give Labour a majority of almost 170 seats and end 14 years of tumultuous Conservative-led government.

Several big names in Conservative politics lost their seats, including former prime minister Liz Truss, whose disastrous tenure in power during 2022 helped pave the way for Labour’s victory on Friday.

Pro-Brexit MPs Jacob Rees-Mogg and former leadership contender Penny Mordaunt also lost. Sunak and his finance minister Jeremy Hunt retained their seats, although Hunt did so unexpectedly.

Sunak’s party is on track to miss exit poll forecasts of 131 seats, the worst electoral performance in its history, as voters punish him for a cost-of-living crisis, and instability and infighting that have seen five different prime ministers take office since the 2016 Brexit vote.

Can the Labour Party get Britain back into its green groove?


Britain, the birthplace of the Industrial Revolution, formerly a giant coal-burning empire, became a “Clean energy superpower.”

At least that is the promise of Keir Starmer, who is running to become the next prime minister. His Labour Party is projected to win parliamentary elections on Thursday, ending the Conservative Party’s 14-year rule.

The Labour Party had made big promises on climate change in its election campaign. But now how these promises will be fulfilled will not only affect the daily lives of the people of Britain but will also affect the country’s position in the world.

The UK is one of history’s leading climate polluters. It was here that the Industrial Revolution began in the 18th century, giving rise to a global economy powered by coal, oil and gas, and with it emissions of greenhouse gases that warm the planet. So the pace and scale of the UK’s energy transition is likely to be closely watched by other industrialised countries and emerging economies alike.

The UK likes to see itself as a global climate leader. In 2008, it became the first of the major industrialised nations to pass a global convention on climate change. Climate change legislationIts emissions have fallen dramatically since then. In 2021, its government set a legally binding target for reducing greenhouse gas emissions 78 percent by 2035Relative to 1990 levels, it is one of the world’s most ambitious climate laws.

Getting there, however, is a tough job. The new government will face a cost-of-living crisis at home, geopolitical turmoil abroad, and extreme weather events fueled by rising fossil fuel emissions.

There are three things that need to be kept in mind when the new government begins its work.

Mr Starmer’s campaign manifesto promised “zero carbon electricity by 2030”.

Luckily for them, the country is already moving in that direction.

It is no longer dependent on coal for its electricity. The last coal-burning power plant is set to shut down in September. According to a report, coal-fired electricity supply has fallen from 40 per cent in 2012 to almost zero today. Analysis by Carbon BriefAn independent climate news site.

The challenge now is to reduce reliance on gas. In 2023, it will supply just over 30 per cent of the UK’s electricity. The government must get this to zero by 2030, or find ways to capture and bury the greenhouse gases produced by gas plants.

Labor leaders have also said they would double wind power capacity on land, quadruple wind power capacity on the sea and triple solar power.

José Garman, executive director of the European Climate Foundation, called the zero-carbon-electricity promise a “broad target” that would require changes to laws approving wind and solar projects.

Oil extraction in the North Sea There was a steady decline The largest decline has occurred in the last 20 years and is expected to continue until mid-century.

Nevertheless, the question of oil and gas licences in the North Sea remains politically important.

Last year, the current Prime Minister Rishi Sunak of the Conservative Party said that Britain should make maximum use of oil and gas from the North Sea. He introduced a system Issue of new licencesAfter which the former Energy Minister had to resign, who said that this would Causing “future harm.”

Mr Starmer’s party has said it would respect existing licences but would refrain from issuing new ones.

Oil and gas companies already face a 75 percent tax in Britain. The incoming Labour government has said it will raise this slightly to 78 percent.

There’s another catch, and that’s Scotland.

Scottish nationalists have pushed for greater control over North Sea oil and gas, as it is in Scottish waters. A drop in production is likely to hit communities on Scotland’s northeastern coast first and foremost, which depend on the industry for jobs.

Unlike the United States, there was broad political consensus in Britain about the need to tackle climate change. In fact, climate action was a favourite of the Conservatives.

Former Prime Minister Margaret Thatcher expressed concern over climate change. theresa maywho is also a Conservative prime minister, led the campaign for a net-zero target by 2050, meaning that Britain must, by law, take the same amount of greenhouse gas emissions out of the atmosphere as the country puts into it by mid-century. In 2021, Boris Johnson’s government pledged to reduce emissions by 78 percent by 2035.

Recently, this target has changed. Mr Sunak described the green transition as too expensive. For example, a plan to ban new petroleum and diesel-powered cars by 2030 was delayed until 2035.

Mr Starmer is likely to reinstate the ban to 2030. He has also promised to double funding for energy efficiency programmes and create a new national energy company, which he says will help reduce the cost of energy Cut down on energy bills,

There is also pressure from the right-wing Reform UK party, led by Nigel Farage, to Abandoning the net-zero target by 2050 All in all, exit polls show Mr Farage’s party will make a surprisingly large gain in parliament, reflecting the rise of the far right across Europe.

Japan’s Finance Ministry confirms foreign exchange vigilance, but refrains from warning of intervention


TOKYO, July 2 (Reuters) – Japan’s finance minister said on Tuesday officials were alert to sharp movements in the currency market as the yen sank to a 38-year low against the dollar, but stopped short of warning of explicit intervention.

The change in the official daily commentary to reporters, in which warnings of intervention have become almost customary, comes at a time when analysts are questioning the effectiveness of such warnings in preventing a sharp fall in the yen.

“Foreign exchange levels are determined by the market, reflecting a complex mix of various factors including inflation, current account balance, market sentiment and speculative moves,” Finance Minister Shunichi Suzuki said at a regular news conference held after a Cabinet meeting.

“We will continue to monitor the market closely,” he added.

Although Suzuki said there had been no change in the government’s stance, the absence of the usual comments about readiness to intervene signaled a change in what had become almost routine for authorities.

Yujiro Goto, managing director and chief FX strategist at Nomura, said official comments on Tuesday indicated little change in tone.

“Repeating the same words over and over again can essentially dilute the effect (of a warning),” he said, adding that no change in wording could be interpreted by investors to mean no immediate action would be taken.

“But I don’t think this (the lack of intervention warnings) suggests that intervention is less likely now than it was before,” he said.

The yen fell to 161.72 per dollar late on Monday, its weakest level since 1986, leaving markets alert for any signs of a yen buying campaign from Tokyo to support the currency.

It has already fallen by more than 12% this year, as the huge interest rate differential between the US and Japan continues to drag on.

Japanese officials, including Suzuki and top currency diplomat Masato Kanda, Escalated His warnings, which came as the yen slid below 160 against the dollar last week, were the latest to drag Japan into intervening in markets by traders.
Suzuki last week Said Officials were “deeply concerned” about the impact of “sharp and one-sided” foreign exchange moves on the economy and would react appropriately to extreme currency moves.

When asked about the effectiveness of verbal interventions at Tuesday’s conference, Suzuki said his comments on foreign exchange are usually in response to reporters’ questions.

He said he was not in a position to comment on their effectiveness.

A weak yen is a boon for Japanese exporters but a headache for policymakers because it raises import costs, boosts inflationary pressures and dampens domestic spending.

The Supreme Court has put a series of federal regulations at risk


The Supreme Court on Friday reduced the authority of executive agencies, overturning a longstanding legal tradition that required courts to acknowledge the expertise of federal administrators in enforcing laws passed by Congress.

Example, Chevron v. Natural Resources Defense CouncilIt is one of the most cited cases in American law. There have been 70 Supreme Court decisions based on Chevron, and 17,000 lower court decisions.

The decision threatens regulation in countless areas, including the environment, health care, and consumer safety.

The vote was by a ratio of 6 to 3, divided along ideological lines.

The conservative legal movement and business groups have long objected to the Chevron decision, based in part on a general hostility to government regulation and in part on the separation of powers-based belief that agencies should have only as much power as Congress has explicitly given them.

Supporters of the doctrine say it allows specialized agencies to fill in gaps in ambiguous laws by establishing uniform rules in their areas of expertise, a practice they say was contemplated by Congress.

Opponents say it is the role of courts, not executive branch officials, to determine the meaning of laws. They also say agencies’ interpretations could change with a new administration and tip the scales in favor of the government in lawsuits, even if it is a party to the case.

The Court decided two nearly identical cases, Loper Bright Enterprises v. Raimondo, No. 22-451, and Relentless v. Department of Commerce, No. 22-1219. Justice Ketanji Brown Jackson was recused from the first case because she participated in it as a federal appeals court judge.

Both cases involved a 1976 federal law that requires herring boats to carry federal observers to collect data to prevent overfishing. Under a 2020 regulation interpreting the law, boat owners were not only required to carry observers, but also pay $700 a day for their monitoring.

Fishermen from New Jersey and Rhode Island sued, arguing that a 1976 law did not authorize the relevant agency, the National Marine Fisheries Service, to impose the fees.

Two appeals courts – one in Washington, the other in Boston – ruled that the deference required by the Chevron decision required a ruling by the government. The United States Court of Appeals for the District of Columbia Circuit in Washington, Government The agency’s interpretation of the 1976 law “to allow industry-funded surveillance was reasonable,” the First Circuit in Boston said. Said that “at a minimum” the agency’s interpretation of the 1976 law was “certainly reasonable.”

Fishermen were represented Cause of Action Institutewhich says its mission is to “limit the power of the administrative state”, and New Civil Liberties AllianceWhich says its purpose is “to defend constitutional liberties from infringement by the administrative state.” Both groups have financial ties to the network of foundations and advocacy organizations funded by Charles Koch, a billionaire who has long supported conservative and libertarian causes.

Forty years ago, when Chevron was ruled on by a unanimous but slimmer six-member Supreme Court, with three justices recusing themselves, it was generally viewed as a victory for conservatives. In response to a challenge from environmental groups, the justices upheld a Reagan-era interpretation of the Clean Air Act that loosened regulation of emissions, saying the Environmental Protection Agency’s reading of the statute was “a reasonable construction” that was “worthy of deference.”

Study finds small streams recently denied protection are a big problem


Last year, the Supreme Court imposed tight restrictions on the federal government’s ability to limit pollution in small rivers, which are dry most of the year and fill only after rain or snowmelt.

Now, a new study finds that these bodies, called ephemeral streams, are even more important to the nation’s waterways than often realized.

This research was published in the Science journal on Thursday.It is estimated that 55 percent of the water flowing through U.S. river basins is sourced by millions of ephemeral streams that flow only periodically. The findings suggest that the Supreme Court ruling, which rolled back protections for those streams, could leave large bodies of water vulnerable to pollution.

“Right now, we regulate large waterways like the Hudson River, but a significant portion of that water is coming upstream from places that can no longer be controlled,” said Craig Brinkerhoff, a doctoral candidate at the University of Massachusetts Amherst who led the study.

For years, politicians, industry groups and environmentalists have debated which water bodies in the United States should fall under the jurisdiction of the Clean Water Act, a sweeping law passed in 1972 that allows the Environmental Protection Agency to limit water pollution. While there is consensus that the law applies to major rivers and lakes, there is debate over whether federal protections should apply elsewhere, such as nearby wetlands or streams that go dry for part of the year.

Environmentalists favor broader protection, arguing that these other water bodies are also important; homebuilders, some industry groups, and conservatives oppose it, as they see it as regulatory overreach.

In May 2023, the Supreme Court The vote was 5 to 4 to limit the scope. The majority of the Clean Water Act decided that the law should apply only to “relatively permanent, standing or continuously flowing bodies of water,” as well as wetlands that have a “continuous surface connection” to those waters.

The decision effectively ended federal protections for up to 4.9 million miles of streams that flow only when it rains, according to EPA officials. which was announced in August He will follow the guidance of the court.

These temporary streams are often overlooked because they look like dry ditches most of the year, said Judd Harvey, senior research hydrologist with the United States Geological Survey. wrote a separate comment “But when it rains, these streams bring a lot of water” that ends up in rivers and lakes, he said of the Science study.

Mr. Brinkerhoff and his colleagues identified millions of temporary streams across the country and used detailed modeling to estimate how much water flows through them.

The study found that in the West, ephemeral streams flow on average only four to 46 days per year but contribute up to 79 percent of river flow. Ephemeral streams contribute about 55 percent of flow on average in river basins across the United States.

Mr. Harvey said he was surprised by the amount of water released from ephemeral streams. “But this is a rigorous and detailed investigation using the best data available in the United States,” he said of the study.

Because so much water passes through these streams, it matters little whether they are polluted or not, the study says. Sediment or excess phosphorus from fertilizer runoff from fields can accumulate in dry streams until heavy rains stir up the pollutants and flush them into larger waterways.

Mr. Brinkerhoff said the study did not try to measure how much pollution is actually passing through these streams. That is a topic for future research. But, he said these streams have a huge impact on water quality.

Even though the EPA can no longer regulate pollution in ephemeral streams, some states still try to do so, said Ciaran Harman, an associate professor of landscape hydrology at Johns Hopkins University. For example, farmers can let grass and other vegetation grow around ephemeral streams to limit erosion and prevent pollutants from flowing into waterways after storms. Yet state plans can vary widely, and it can often be difficult for states to coordinate on water regulation.

John Devine, who leads the federal water policy team at the Natural Resources Defense Council, an environmental group, said that in the past, the EPA often used new scientific research to update and sometimes expand the scope of water regulations. “Regulators will look at whether different bodies of water contribute to downstream water quality, and if so, whether they should be protected,” he said. “Ultimately this is a scientific inquiry.”

But Mr. Devine said that after the Supreme Court’s decision, the EPA’s ability to modify those rules has been significantly curtailed. “You would really need congressional intervention,” he said.

Tencent’s ‘Dungeon & Fighter’ game dominates China’s mobile download charts


BEIJING, June 26 (Reuters) – Tencent Holdings Ltd (0700.HK)opens a new tab The recently launched “Dungeon & Fighter” (DNF Mobile) has made a stellar start and continues to dominate Apple’s top-grossing charts. (AAPL.O)opens a new tab Industry data revealed that the company has been working on the iOS platform in China for about a month.

The game, which launched in the world’s largest gaming market on May 21, crossed the $100 million revenue mark in just 10 days, according to a report released this week by data analytics firm Sensor Tower.

It also topped the global mobile game revenue growth chart for May and ranked 8th in overall revenue.

According to a separate report from Sensor Tower released on June 17, in the first 10 days of launch, DNF Mobile’s revenue in China’s iOS market surpassed the combined earnings of Tencent’s other popular titles “Honor of Kings” and “PUBG Mobile.”

The surge led to a 12% rise in Tencent’s mobile game revenue in May, according to Sensor Tower.

The DNF mobile title, based on a popular PC franchise, had been available internationally for several years. Its launch in China was delayed due to Beijing’s temporary ban on approval of new games.

DNF Mobile’s early success comes amid ongoing tensions between Tencent and smartphone vendors over gaming revenue sharing.

Earlier this month, Tencent pulled Citing expiration of the contract, the company removed the game from select Android app stores.

Game developers in China have long had disputes with distributors over issues such as revenue sharing, as mobile games have become increasingly popular in the wider game market. The standard 50% revenue split has often been a point of contention.

Volkswagen to invest up to $5 billion in EV maker Rivian


German automaker Volkswagen said on Tuesday it would invest up to $5 billion in Rivian, an electric truck maker that has struggled to turn a profit. The two companies will also collaborate on software for electric vehicles.

The deal creates an unusual alliance between the world’s second-largest carmaker and an electric vehicle start-up that has struggled to live up to investor expectations that it would achieve the kind of success that made Tesla the world’s most valuable automaker.

If successful, the partnership would address weaknesses in both companies. It would give Volkswagen the software expertise that auto analysts say it lacks. And Rivian would benefit, in addition to cash, from the manufacturing expertise of an automaker that makes about 10 million vehicles a year from factories around the world.

Volkswagen said it would initially invest $1 billion in Rivian and increase it to $5 billion over time. The investment represents a major vote of confidence in Rivian, which is Thousands of dollars in damage on each vehicle sold.

Rivian’s pickups and sport utility vehicles have received rave reviews in the automotive press, but the company has struggled to grow its sales. Manufacturing in our own factory in Normal, Illinois

Rivian’s shares rose 35 percent in extended trading on Tuesday after the deal was announced.

The electric vehicle market is divided between companies like Tesla and Rivian, which make only battery-powered cars, and established carmakers like Volkswagen, General Motors and Toyota, which often struggle to master new technology.

Except for Tesla, no new American carmaker specializing in electric vehicles has gained significant market share. Fisker And Lordstown Motorshas ceased production and filed for bankruptcy protection.

Auto analysts have long considered Rivian one of the most promising electric vehicle start-ups, partly because it has raised billions of dollars in investment. Amazon is one of its largest shareholders and a major customer for the company’s delivery vans.

Ford Motor was once a large shareholder in Rivian, and the two companies once said they would build SUVs together. But that plan never came to fruition, and Ford sold most of its Rivian shares.

Rivian has been trying to cut costs lately — in March it indefinitely postponed plans to build $5 billion factory near Atlanta — in an effort to stay alive long enough to retrieve his $45,000 SUV.

The cheapest vehicle the company currently sells, the R1T pickup, starts at around $70,000, a price that has limited its sales to only wealthy early adopters. Its SUV, the R1S, starts at $75,000. Even at these prices, Rivian lost $39,000 per vehicle sold in the first three months of the year.

Volkswagen said vehicles using software developed by the new joint venture would go on sale in the second half of the decade. The two companies will continue to market their vehicles separately.

Monkeys in Puerto Rico recover after Hurricane Maria


Hurricane Maria caused widespread devastation in the Caribbean region, not just to people but to wildlife as well. Even five years after the storm, some of its effects still remain.

Cayo Santiago, a small island off the southeast coast of Puerto Rico, is a great example of this. It transformed from a lush forest overnight to a desert-like area of ​​sand, with mostly skeleton-like trees.

This has caused a major problem for the macaques living on the island. The monkeys rely on shade to stay cool in the heat of the tropical day, but the storm has greatly reduced that resource by wiping out trees.

Rhesus macaques are known to be some of the most quarrelsome primates on the planet, with strict social hierarchies maintained through aggression and competition. So it’s conceivable that simian wars would break out over the few remaining shady parts of the island.

But that didn’t happen. Instead, the macaques did something inexplicable: they began to mingle with each other.

“This was not really what we expected,” said Camille Testard, a behavioral ecologist and neuroscientist at Harvard University. “Instead of becoming more competitive, individuals expanded their social networks and became less aggressive.”

A paper written by Dr. Testard and his colleagues, Published Thursday in the journal Scienceoffers an explanation for this unexpected development. They found that monkeys who learned to share shade after a storm had a better chance of surviving than those who remained pugnacious.

Researchers introduced the macaque species to Cayo Santiago in 1938.Credit…Ramon Espinosa/Associated Press

Scientists have documented numerous cases of species responding to environmental pressures with physiological or morphological adaptations. But Dr. Testard said the new study is one of the first to suggest that animals can also respond with persistent changes in their social behavior.

He and his colleagues took advantage of nearly 12 years of data collected at the Cayo Santiago Field Station, the world’s longest-running primatology field site. The researchers brought rhesus macaques to the 38-acre island in 1938 and have been studying them ever since.

The approximately 1,000 macaques living on the island roam freely, but are fed by field station staff. “Access to food is not the main point of contention,” Dr. Testard said. “Shade is the main issue to avoid heat stress.”

Daytime temperatures at Cayo Santiago often exceed 100 degrees Fahrenheit, or about 38 Celsius, which can be deadly for monkeys trapped in the sun.

After Hurricane Maria destroyed most of the island’s trees, Dr. Testard and her colleagues expected the macaques might invest more in forming close alliances so they could join forces to secure shade. But “the complete opposite” happened, she said. Instead the monkeys invested more in looser partnerships with larger numbers of animals, and they became more tolerant of each other overall.

Dr. Testard said he suspects this is because fighting is an energy-intensive activity that generates more bodily heat and poses a greater threat to individuals, “regardless of whether there’s another monkey next to me or not.”

During the hottest hours of the afternoon, the researchers observed the macaques cluster together in thin patches of shade. But even when temperatures were cooler, the animals gathered in larger groups than they did before the storm, Dr. Testard said.

Not all monkeys followed the path of peace, but those who persisted in aggression paid a heavy price. There was no change in the overall mortality rate of the macaque population after the storm. But monkeys that had more friendly relationships saw a 42 percent reduction in mortality because they were less likely to suffer stress due to the heat.

“Who dies, and for what reasons, has changed,” Dr. Testard said.

Behavioral ecologist Noah Pinter-Wollman of the University of California, Los Angeles, who was not involved in the research, said the “fascinating” findings are “a wonderful example of how being social can mitigate the negative effects of environmental change.”

Julia Fischer, a behavioral biologist at the German Primate Center in Göttingen, who was not involved in the work, said the “extremely well-conducted study” highlighted the importance of behavioral plasticity in helping animals survive when their habitat is overturned. “In view of climate change, this is extremely important,” she said.

Whether other animals might also respond to environmental upheaval by adjusting their social norms is “going to be very much species- and context-dependent,” Dr. Testard said. However, humans probably fall into that category. For example, people often come together after natural and human-caused disasters.

However, Dr. Testard said there are limits to this. If resources become too scarce, humans could fall into a Mad Max-like catastrophe of violent competition. “Hopefully we will work together rather than fight,” he said. “But that’s a big guess.”

Not all monkeys followed the path of peace, but those who persisted in aggression paid a heavy price. There was no change in the overall mortality rate of the macaque population after the storm. But monkeys that had more friendly relationships saw a 42 percent reduction in mortality because they were less likely to suffer stress due to the heat.

“Who dies, and for what reasons, has changed,” Dr. Testard said.

Behavioral ecologist Noah Pinter-Wollman of the University of California, Los Angeles, who was not involved in the research, said the “fascinating” findings are “a wonderful example of how being social can mitigate the negative effects of environmental change.”

Julia Fischer, a behavioral biologist at the German Primate Center in Göttingen, who was not involved in the work, said the “extremely well-conducted study” highlighted the importance of behavioral plasticity in helping animals survive when their habitat is overturned. “In view of climate change, this is extremely important,” she said.

Whether other animals might also respond to environmental upheaval by adjusting their social norms is “going to be very much species- and context-dependent,” Dr. Testard said. However, humans probably fall into that category. For example, people often come together after natural and human-caused disasters.

However, Dr. Testard said there are limits to this. If resources become too scarce, humans could fall into a Mad Max-like catastrophe of violent competition. “Hopefully we will work together rather than fight,” he said. “But that’s a big guess.”
