Cow may be biggest mammal if humans keep up extinctions: Study

Oslo, May 12: The spread of humans around the world from Africa thousands of years ago wiped out big mammals in a shrinking trend that could make the cow the biggest mammal on Earth in a few centuries` time, a scientific study said on Thursday.

The spread of hominims - early humans and relatives such as Neanderthals - from Africa coincided with the extinction of mammals such as the mammoths, sabre-toothed tiger and glyptodon, an armadillo-like creature the size of a car.

"There is a very clear pattern of size-biased extinction that follows the migration of hominims out of Africa," lead author Felisa Smith of the University of New Mexico told Reuters of the study published in the journal Science.

Humans apparently targeted big species for meat, while smaller creatures such as rodents escaped, according to the report examining trends over 125,000 years.

In North America, for instance, the mean body mass of land-based mammals has shrunk to 7.6 kg (17 lbs) from 98.0 after humans arrived.

If the trend continues "the largest mammal on Earth in a few hundred years may well be a domestic cow at about 900 kg" (2,000 lbs), the U.S. team wrote.

That would mean the loss of creatures including elephants, giraffes and hippos. In March, the world`s last male northern white rhino died in Kenya.

But other research casts doubt on a continued shrinking of mammals, partly because of conservation efforts to stave off threats to wildlife such as climate change, loss of forest habitats and pollution and expanding cities.

Thomas Brooks, chief scientist of the International Union for Conservation of Nature (IUCN) who was not involved in the study, said the projection of ever smaller mammals was "doom and gloom."

"Happily I don`t think it`s very likely," he told Reuters, saying that other research suggests that large animals such as elephants are more likely to benefit in protected areas than smaller ones.

And a Red List of threatened species, maintained by the IUCN, also lists some wild mammals roughly the size of a cow - such as the African buffalo or the brown bear - as unendangered.

The Science study also excludes marine mammals such as the blue whale, the largest creature that has ever existed. It is endangered on the Red List but the populations are rising after a moratorium on hunts.

Smith said that "my optimist hat would like to say that it`s not going to happen because we love elephants`." But she said populations of large land mammals were falling and "declining population is the trajectory to extinction."

New Delhi, Feb 18: Election strategist-turned-politician Prashant Kishor on Tuesday questioned the Nitish Kumar government's development model, even as he sneered at the chief minister for making ideological compromises to stay in an alliance with the BJP.

Kishor, who has been vocal about his opposition to the Citizenship (Amendment) Act (CAA), said Kumar needs to spell out whether he is with the ideals of Mahatma Gandhi or those who support Nathu Ram Godse.

"Nitish ji has always said that he cannot leave the ideals of Gandhi, JP and Lohiya... At the same time, how can he be with the people who support the ideology of Godse? Both cannot go together. If you want to stay with the BJP, I don't have any problem with it but you cannot be on both sides," he said.

"There has been a lot of discussion between me and Nitish-ji on this. He has his thought process and I have mine. There have been differences between him and me that the ideologies of Godse and Gandhi cannot stand together. As the leader of the party you have to say which side you are on," he added.

In a direct assault on Kumar's model of governance, Kishor said Bihar was the poorest state in 2005 and continues to be so.

"There has been development in Bihar during the last 15 years, but the pace has not been as it should have," he added.

London, Feb 21: Scientists have discovered a new species of land snail, and have named it Craspedotropis Greta Thunberg in honour of the Swedish activist Greta Thunberg for her efforts to raise awareness about climate change.

According to the study, published in the Biodiversity Data Journal, the newly discovered species belongs to the so-called caenogastropods -- a group of land snails known to be sensitive to drought, temperature extremes, and forest degradation.

The scientists, including evolutionary ecologist Menno Schilthuizen from Naturalis Biodiversity Center in the Netherlands, said the snails were found very close to the research field station at Kuala Belalong Field Studies Centre in Brunei.

They added that the snails were discovered at the foot of a steep hill-slope, next to a river bank, foraging at night on the green leaves of understorey plants.

The effort aided by amateur scientist J.P. Lim, who found the first individual of the snail said, "Naming this snail after Greta Thunberg is our way of acknowledging that her generation will be responsible for fixing problems that they did not create."

"And it's a promise that people from all generations will join her to help," Lim said.

The researchers said they approached Thunberg who said that she would be "delighted" to have this species named after her.

The study work including, fieldwork, morphological study, and classification of identified specimen was carried out in a field centre with basic equipment and no internet access, the scientists said.

According to the study, the work was done by untrained ‘citizen scientists’ guided by experts, on a 10-day taxon expedition.

"While we are aware that this way of working has its limitations in terms of the quality of the output (for example, we were unable to perform dissections or to do extensive literature searches), the benefits include rapid species discovery and on-site processing of materials," the researchers wrote in the study.

Mar 10: Indian energy tycoon Mukesh Ambani is no longer Asia’s richest man, relinquishing the title to Jack Ma after oil prices collapsed along with global stocks.

The rout, exacerbated by mounting fears that the spread of the novel coronavirus will thrust the world into a recession, erased $5.8 billion from Ambani’s net worth on Monday and pushed him to No. 2 on the list of Asia’s richest people, according to the Bloomberg Billionaires Index. Ma, the Alibaba Group Holding Ltd. founder who relinquished the No. 1 ranking in mid-2018, is back on top with a $44.5 billion fortune, about $2.6 billion more than Ambani.

Oil plunged the most in 29 years on Monday as Saudi Arabia and Russia vowed to pump more in a struggle for market share. The slump comes just as the coronavirus is spurring the first decline in demand in more than a decade. That raises questions about whether Ambani’s flagship Reliance Industries Ltd. will be able to cut net debt to zero by early 2021, as he has pledged. The plan hinges on a proposal to sell a stake in the group’s oil and petrochemicals division to Saudi Arabian Oil Co., the world’s biggest crude producer.

While the coronavirus has curtailed some of tech giant Alibaba’s businesses, the damage has been mitigated by increased demand for its cloud computing services and mobile apps.

Reliance Industries, by comparison, has no such silver lining. The Indian conglomerate’s shares plunged 12% on Monday, the most since 2009, extending this year’s decline to 26%. Alibaba’s American depositary receipts have slipped 6.8% so far in 2020.

Ma reclaims crown after Reliance shares were pummeled in 2020.

Few of the world’s billionaires fared well in Monday’s collapse as the S&P 500 Index and Dow Jones Industrial Average each plunged more than 7.5%, the most since the 2008 financial crisis, threatening to end the longest bull market in history. But no one did worse than those whose fortunes are underpinned by oil. Wildcatter Harold Hamm’s fortune was cut almost in half to $2.4 billion and fellow oil magnate Jeff Hildebrand lost $3 billion, bumping both from Bloomberg’s 500-member wealth ranking.

In a pivot toward new businesses such as telecommunications, technology and retail, Ambani’s Reliance Industries has piled on billions of dollars of debt over the years.

It spent almost $50 billion -- most of it funded by borrowings -- to build Reliance Jio Infocomm Ltd., which became India’s No. 1 wireless carrier within about three years of its debut. As the mobile venture took off, Ambani also unveiled plans for an e-commerce empire to rival Amazon.com Inc. in India.

Addressing concerns over the liabilities, Ambani pledged in August to cut the group’s net debt to zero from about $21 billion as of last March. The Aramco deal is crucial to that plan for which Reliance Industries has valued its oil-to-chemicals division at $75 billion including debt, implying a $15 billion valuation for the 20% stake that’s for sale.

Signs of a potential delay to that deal unnerved some investors, hammering the stock since it touched a record high on Dec. 19.

Reliance Industries expected the Aramco transaction to be completed by March, but people familiar with the matter said in February that talks were still ongoing to bridge differences between the two parties over the deal’s structure.

Adding to the uncertainty, Indian Prime Minister Narendra Modi’s administration has petitioned a court to halt the proposed stake sale, threatening a key source of funds needed to pare net debt.

But Ambani, 62, may soon bounce back from the setback, said Harish H.V., managing partner at ECube Investment Advisors in Bengaluru, India.

“The game isn’t over,” he said. “Ambani has successfully built a robust business model which would keep him in the game. Moreover, his telecom business will start yielding results in coming years.”
