Adelie penguin population sees rapid decline: Scientists_我的网站

方谬神探

A | Vladimir Putin has prepared a cunning new “raw materials trap” relying on Bolivia’s fledgling lithium mining industry, with the trap expected to “snap shut” and leave the West again dependent on Russia for its raw material needs, Welt contributor Tobias Kaufer fears.,Pointing to the Latin American nation’s massive, untapped deposits of lithium, Kaufer expressed concerns over Russia’s interest in helping Sucre tap these resources, which are crucial for the production of batteries for electric vehicles.,According to the US Geological Survey, Bolivia’s proven lithium reserves are the largest in the world, with the country’s 21 million tons ahead of Argentina and Chile (which have 19 and 9.8 million tons-worth of reserves, respectively, and together account for more than 30 percent of global lithium output).,“Those with access to the deposits can have a say in the commodity’s prices and availability. Russia apparently has particularly good chances in Bolivia at the moment,” Kaufer wrote. For Europe, he warned, Moscow’s success in the lithium ‘poker game’ would make the commodity another area where the EU depends on Russia, just like with oil and gas.,Russia’s success will be contingent on “the outcome of the Bolivian political crime thriller,” the contributor stressed, pointing to the raging struggle between President Luis Arce, a member of former president Evo Morales’ Movement for Socialism party, and right-wing forces backed by the US attempting to overthrow leftist forces.,Ex-Bolivian President Jeanine Anez Sentenced to 10 Years in Prison Over 2019 Coup11 June, 01:54 GMT,“This is where Russia comes in. Morales is considered a clear supporter of Vladimir Putin,” Kaufer wrote, recalling the former president’s calls for an “international mobilization to stop the interventionist expansionism of NATO and the United States” in March following the escalation of the crisis in Ukraine, and years of efforts by Sucre to shore up ties with Moscow during his presidency.,“If Moscow now succeeds in supporting the socialist’s return to power, the path to the lithium deposits would be clear. At the very least, Morales could urge President Arce to sign a deal with the Russians,” the Welt contributor believes.,Rosatom, the Russian state nuclear giant, has expressed interest in helping Bolivia tap its lithium riches, and is one of six companies which have applied for their development. Others include Lilac Solutions (a US-based start-up with investments from BMW and Bill Gates’ Breakthrough Energy Ventures), Chinese battery giant CATL, and three other Chinese companies.,Along with its interest in Bolivia’s lithium, Rosatom has teamed up with Norilsk Nickel to mine for lithium ores in Russia’s Murmansk region. Last year, the company also announced plans to build a major lithium ion cell manufacturing facility in Kaliningrad, with the ambitious project hoping to begin churning out up to 4 GWh worth of batteries, or about 0.5 percent of total global demand, by 2024.,Morales' Legacy: Bolivian Joint Nuclear Project With Russia's Rosatom Unique for Latin America10 June 2021, 16:53 GMT。 Canberra, Oct 12 (UNI) Australia's top Antarctic scientists have reported a rapid decline in a population of Adelie penguins.

According to research published by the Australian Antarctic Division (AAD) on Tuesday, a large Adelie population off the East Antarctic coast has declined by 43 per cent over the last decade.

Ecologists from the AAD, led by Louise Emmerson and Colin Southwell, surveyed 52 islands along the 100-km coastline.

They found the number of occupied nests fell from 176,622 to 99,946 in that period.
Their findings are contrary to other Adelie penguin populations in east Antarctica where numbers have been stable.

The most widespread penguin species, the Adelie is found along the entire Antarctic coast. Models had predicted the particular population observed by the AAD would continue to grow.

Researchers concluded a change in environmental conditions was the cause of the decline.

"We think this population decline was initially triggered by five years of extensive summer sea ice adjacent to the colony in the mid-2000s, which hampered access to the adults' foraging areas and saw virtually no chicks survive," Emmerson said in a media release.

"The frequency of these unfavorable breeding conditions subsequently remained high, and fledgling survival also began to decrease. These two processes together resulted in a more rapid population decline than would be expected if they had been acting in isolation."

She warned that the smaller the population becomes the harder it will be for individuals to survive.

"It may be that the old adage of safety in numbers is playing out for the fledglings in the vast and harsh Southern Ocean, although exactly why and how needs further investigation," Emmerson said.
