Elephant extinction may raise carbon dioxide levels in atmosphere: Study

Washington D.C., Aug 3: Forest elephants engineer the ecosystem of the entire central African forest, but their catastrophic decline toward extinction has catastrophic implications for carbon policy.

One of the last remaining megaherbivores, forest elephants shape their environment by serving as seed dispersers and forest bulldozers as they eat over a hundred species of fruit, trample bushes, knock over trees and create trails and clearings. Their ecological impact also affects tree populations and carbon levels in the forest, researchers report, with significant implications for climate and conservation policies.

In a paper published in the journal of 'Nature Geoscience,' researchers found that elephant populations in central African forests encourage the growth of slow-growing trees with the high wood density that sequesters more carbon from the atmosphere than fast-growing species which are the preferred foods of elephants.

As forest elephants preferentially browse on the fast-growing species, they cause high levels of damage and mortality to these species compared to the slow-growing, high wood density species. The collapse of forest elephant populations will likely, therefore, causes an increase in the abundance of fast-growing tree species at the expense of slow-growing species, and reduce the ability of the forest to capture carbon.

Stephen Blake, one of the researchers of the study, spent 17 years in central Africa doing, among other things, applied for research and conservation work with elephants. While there, he collected a data set on forest structure and species composition in the Nouabale-Ndoki Forest of northern Congo.

In the current study, Blake's collaborators developed a mathematical computer model to answer the question 'What would happen to the composition of the forest over time with and without elephant browsing?'

To find out, they simulated elephant damage through browsing in the forest and assumed they browse certain plant species at different rates. Elephants prefer fast-growing species in more open spaces. As they feed and browse, they cause damage, knocking off a limb or breaking a shrub. The model calculated feeding and breakage rates along with elephant mortality rates to see their effect on certain woody plants.

"Lo and behold, as we look at numbers of elephants in a forest and we look at the composition of forest over time, we find that the proportion of trees with high-density wood is higher in forests with elephants," Blake said.

"The simulation found that the slow-growing plant species survive better when elephants are present. These species aren't eaten by elephants and, over time, the forest becomes dominated by these slow-growing species. Wood (lignin) has a carbon backbone, meaning it has a large number of carbon molecules in it. Slow growing high wood density species contain more carbon molecules per unit volume than fast-growing low wood density species. As the elephants "thin" the forest, they increase the number of slow-growing trees and the forest is capable of storing more carbon."

These findings suggested far-ranging ecological consequences of past and present extinction. The loss of elephants will seriously reduce the ability of the remaining forest to sequester carbon. Trees and plants use carbon dioxide during photosynthesis, removing it from the atmosphere. For this reason, plants are helpful in combating global warming and serve to store carbon emissions.

Without the forest elephants, less carbon dioxide will be taken out of the atmosphere. In monetary terms, forest elephants represent a carbon storage service of $43 billion.

"The sad reality is that humanity is doing its best to rid the planet of elephants as quickly as it can. Forest elephants are rapidly declining and facing extinction. From a climate perspective, all of their positive effect on carbon and their myriad other ecological roles as forest gardeners and engineers will be lost," Blake concluded.

Russia says it is "extremely hard to believe" that Daesh could have staged the recent hugely deadly attack on a Moscow concert hall that the country's intelligence and security officials have blamed on Ukraine and its Western backers.

Four gunmen burst into the Russian capital's Crocus City Hall on Friday and began shooting at the people, who were attending an event. The Takfiri terrorist group has allegedly claimed responsibility for the massacre that killed at least 143.

Speaking on Wednesday, however, Russian foreign ministry spokeswoman Maria Zakharova cast that claim into serious doubt.

"In order to ward off suspicions from the collective West, they urgently needed to come up with something, so they resorted to ISIS (Daesh), pulled an ace out of their sleeve, and literally a few hours after the terrorist attack, the Anglo-Saxon media began disseminating precisely these versions," she said.

The chief of the Russian internal intelligence (FSB), Alexander Bortnikov has suggested that not only Ukraine, but also the United States and Britain might have been behind the shooting.

The Russian Federal Security Service has also said the gunmen planned to travel to Ukraine, where they were to be welcomed as "heroes." The FSB said Western intelligence services aided the attackers.

Russian President Vladimir Putin has also suggested that Ukraine stood to derive benefit from the attack and that Kiev might have played a role.

He has said that someone on the Ukrainian side had prepared a "window" for the gunmen to escape across the border before they were captured in western Russia on Friday night.

New Delhi, Mar 13: The Supreme Court on Friday took exception to the State Bank of India (SBI) for not disclosing complete details of Electoral Bonds, including unique alfa numeric numbers, furnished to the Election Commission for uploading on the website.

A five-judge Constitution bench led by Chief Justice of India D Y Chandrachud issued notice to the SBI seeking its response on Monday after the court was informed that the issuing bank for the Electoral Bonds has not disclosed unique alfa numeric number of each bond.

"They have not disclosed the bond numbers. It has to be disclosed by the State Bank of India. All details have to be provided by the SBI," the bench, also comprising Justices Sanjiv Khanna, B R Gavai, J B Pardiwala and Manoj Misra, noted.

Senior advocate Kapil Sibal said as per the Constitution bench judgment of February 15, 2024, all details were to be disclosed.

Solicitor General Tushar Mehta submitted since the SBI was a party to the judgment, notice may be issued to it.

The court said the counsel for SBI should have been here.

"If you see the judgment, we have specified that bond numbers have to be provided," the bench said.

Advocate Prashant Bhushan appeared for the main petitioner Association for Democratic Reforms (ADR).

On an application by the EC, the bench said the details of Electoral Bonds furnished by the poll panel before the top court should be scanned and returned to it for the purpose of uploading on the website.

The Election Commission through advocate Amit Sharma filed a plea in the Supreme Court seeking a direction to release data on electoral bonds furnished to the top court in terms of previous orders of April 12, 2019 and November 2, 2023.

As per March 11, 2024 order, the Election Commission on Thursday uploaded the data on electoral bonds furnished to it by the SBI.

However, in an application, the poll panel said it had furnished to the Supreme Court a number of sealed envelopes, containing details on EBs encashed by the political parties, during the course of hearing in the matter.

It sought a direction for the return of those sealed envelopes to comply with the directions to upload it on the website as per order of March 11.

On Monday, the Supreme Court had told the SBI to furnish details of purchasers of Electoral Bonds and names of political parties redeemed those instruments by March 12 to the Election Commission, rejecting its plea for extension of time until June 30 for the purpose.

It had then directed the Election Commission to publish the information provided by the SBI on its website on March 15.

In its February 15, 2024 judgment, the SC had declared the Electoral Bonds scheme, introduced in 2018 for donation to political parties, as "unconstitutional" for being violative of the right to information.

The Income Tax department has issued a notice of approximately Rs 1,800 crore to the Congress party, exacerbating its financial concerns ahead of the crucial 2024 Lok Sabha elections, multiple reports revealed on Friday.

The development comes after the Delhi High Court rejected the party's plea challenging reassessment proceedings for four assessment years.

The new demand pertains to assessment years 2017-18 to 2020-21 and includes penalties and interest. The Congress party now awaits reassessment for three other assessment years, expected to conclude by Sunday, the stipulated deadline, said a report.

Congress lawyer and RS MP Vivek Tankha alleged that the fresh notice of nearly Rs 1,800 crore was served on the party on Thursday without key accompanying documents.

"We received the demand notice without assessment orders. The govt appeared keener to serve us with demand rather than issue us reasons for reassessment," a news paper quoted Tankha as saying. He further added, "this is how the main opposition party is being strangled financially, and that too during the Lok Sabha elections".

Delhi HC rejects plea

The Delhi High Court, on Thursday, dismissed petitions filed by the Congress challenging the initiation of tax reassessment proceedings spanning four years by tax authorities. Justices Yashwant Varma and Purushaindra Kumar Kaurav, comprising the bench, stated that the pleas were rejected in line with their earlier decision to abstain from intervening in the reopening of reassessment for an additional year.

The subject matter of the case pertained to assessment years from 2017 to 2021.

In a previous petition dismissed the week before, the Congress party had contested the initiation of reassessment proceedings concerning assessment years 2014-15 to 2016-17.

The High Court dismissed the plea, citing that the tax authority had prima facie gathered "substantial and concrete" evidence warranting further scrutiny. The tax department alleged that approximately Rs 520 crore had evaded assessment during these three years.

Additionally, the department revealed that searches conducted on entities, including some purportedly linked to Karnataka deputy chief minister D K Shivakumar and a company in Surat, had uncovered cash transactions involving Congress. These transactions were cited as violations, disqualifying the party from tax exemption available to political parties.

In the absence of exemption, parties are treated as "association of persons" and are obligated to pay taxes on their reported income. Moreover, the cash transactions are included in their total income.
