Tennis, boxing, football players support anti-murder demonstrators

Racket down, hands up challenge from tennis players. Tribute to George Floyd

Some popular tennis players like Serena Williams, Gael Monfils, Naomi Osaka, Coco Gauff are showing their sympathy to George Floyd (46) who died after being arrested by police officers including Derek Chauvin outside a shop in Minneapolis, Minnesota.

Chauvin killed George Floyd by kneeling on Mr Floyd’s neck while he was pinned to the floor. The players sent the sympathy via social media in the racket down, hands up challenge.

Canadian tennis player Ayan Broomfield and Sierra Leonese American player Frances Tiafoe are in the video.

Translated from Dutch NOS radio today:

“We want to make a small gesture to raise awareness about the unjust deaths of many African Americans here in this country,” said 22-year-old Broomfield. “This is definitely bigger than tennis and we all need to use our platform to get together regardless of class, gender, race, ethnicity or any other category.”

It is not just tennis, but boxing too.

Israel Adesanya Emotional Speech & More at George Floyd Protest in New Zealand

UFC Middleweight Champion Israel Adesanya went to the protests for George Floyd in Auckland, New Zealand yesterday. He gave an emotional speech before the march on all of the terrible things going on and his on experience with dealing with racism.

He also said a few things on the way and later on after the protest too.

It is not just tennis and boxing, but football too.

This tweet by Liverpool football club player Virgil van Dijk shows Virgil and his teammates taking a knee in the Anfield Road stadium in Liverpool, England. This gesture as a protest against police brutality originated with American footballer Colin Kaepernick.

The players of Dutch club PSV did likewise.

‘Don’t punish anti-racist footballers’, FIFA says

Footballer Jadon Sancho shows George Floyd solidarity shirt

Translated from Dutch NOS radio today:

World football association FIFA has called on national football associations to use ‘common sense’ and to consider not imposing sanctions on players who seek justice during matches for black American George Floyd, who was killed by police brutality.

It is a remarkable position by FIFA, which has strictly monitored since football regulations in 2014 that players do not convey political, religious or personal messages during football matches, for example by writings on their undershirts. FIFA, however, makes an exception for the statements of support to Floyd, given the huge impact of the event in Minneapolis. ..

Yellow card

In the Bundesliga [German professional soccer competition] last weekend, various players reflected on the violent police action against Floyd. Eg, Jadon Sancho of Borussia Dortmund showed the text ‘Justice for George Floyd’ after his first goal against SC Paderborn.

Because the young Englishman took off his shirt, he received a yellow card. Teammate Achraf Hakimi, who had the same message but only pulled his jersey up, was spared that.

Schalke 04 player Weston McKennie wore an armband with the same text on Saturday, while Marcus Thuram of Borussia Mönchengladbach knelt on Sunday after his first hit, the sign of protest against racial violence introduced in 2016 by American football player Colin Kaepernick.

Peaceful anti-murder demonstrators attacked for Trump

Keeanga-Yamahtta Taylor on how racism & racial terrorism fueled nationwide anger

In the largest nationwide uprising since the 1960s, protesters shut down cities across the United States over the weekend following the police killing of George Floyd, an African American man in Minneapolis. “These are not just repeats of past events,” says scholar Keeanga-Yamahtta Taylor. “These are the consequences of the failures of this government and the political establishment … to resolve these crises.”

Translated from Dutch NOS radio today:

Washington DC Mayor Muriel Bowser is very upset at police brutality shortly before President Trump‘s speech. Prior to the speech, peaceful protesters were dispersed with batons and tear gas. She criticizes that it happened before curfew.

The police drove away the peaceful protesters violently, in order to enable Trump to have a photo op with a bible in his hand at the Washington, DC Episcopal church.

How loggerhead sea turtles help biodiversity

This november 2019 video is called Facts: The Loggerhead Sea Turtle.

From Florida State University in the USA:

Loggerhead sea turtles host diverse community of miniature organisms

June 1, 2020

There is a world of life on the backs of loggerhead sea turtles, and it’s more abundant and diverse than scientists knew.

An international team led by Florida State University researchers found that more than double the number of organisms than previously observed live on the shells of these oceanic reptiles, raising important questions about loggerhead sea turtle ecology and conservation.

The study was published in the journal Diversity.

“This suggests loggerhead turtles are hotspots for organism abundance and biodiversity,” said Jeroen Ingels, a researcher with the Florida State University Coastal and Marine Laboratory and lead author of the study. “We suspect that larger organisms that are able to form structures serve as habitats for microscopic creatures and allow for greater levels of abundance and biodiversity.”

Researchers discovered this organism diversity by sampling meiofauna, which are organisms roughly between 1 millimeter and about 0.032 millimeters in size.

The researchers specifically focused on a type of aquatic meiofauna called nematodes, also known as roundworms. Previous research had not considered these tiny creatures when surveying the communities of organisms that live on the backs of loggerhead sea turtles.

“To find nematodes on loggerhead turtle carapaces is no surprise, but when we compared their numbers and diversity to those from other hard surfaces or even on marine plant life, we realized their carapaces abound with this microscopic life, the extent to which had hardly been documented in the past,” Ingels said.

The FSU researchers, together with a team from Brazil led by Professor Giovani dos Santos and Professor Yirina Valdes, sampled the shells from 24 loggerhead turtles that migrated to Florida’s St. George Island in the summer of 2018 to lay eggs.

The researchers examined a forward, middle and posterior section of each shell to see if the different areas had different microscopic communities. To collect their samples, they removed barnacles, then scraped the shells and sponged them down to carefully gather every living creature.

They found thousands of meiofauna organisms. One turtle had more than 146,000 individual organisms living on its carapace. Researchers also found that the posterior section of the shells, closest to the rear flippers, had different communities and a higher diversity of species.

Previous studies of loggerheads had found fewer than 100 different species of any kind living on their shells. By including the nematodes found in this new study, the researchers added at least 111 new species to the list of organisms that can live on the backs of loggerheads. That count doesn’t include other types of meiofauna, meaning the number could be even greater.

The research may help explain a paradox around these miniature creatures: How can the same types of aquatic meiofauna be found in different parts of the world, hundreds or even thousands of miles away? Researchers think they are able to travel large distances on the backs of sea turtles, which could help explain their widespread distribution.

The researchers also found that individual turtles harbor significantly different communities of meiofauna living on their shells.

“Were these turtles colonized by microorganisms in different places?” asked Ingels. “It’s exciting because it means we may be able to infer where loggerheads have been based on the microscopic communities on their shells.”

Tens of thousands of microscopic organisms can colonize loggerhead turtles, which visit remote coasts and beaches during their migration. It makes sense that there would be a connection between the locations frequented by the turtles and the places where the same meiofauna are found, Ingels said. A better understanding of that link could help inform conservation practices for these reptiles.

“Information on key areas used by loggerhead turtles is crucial to inform their management, as it helps identify key threats that they are exposed to,” said Mariana Fuentes, a co-author of the article and assistant professor of oceanography in the FSU Department of Earth, Ocean and Atmospheric Science.

This research was funded by the Florida Sea Turtle License Plate Grant and the PADI Foundation.
