Global frog pandemic may become even deadlier as strains combine

first_imgBatrachochytrium dendrobatidis – Bd for short – causes a disease called chytridiomycosis that affects a frog’s ability to absorb water and electrolytes through its skin. By 2007, Bd had spread around the world and had been implicated in the decline or extinction of some 200 species.A new study finds that hybridization between a native strain of Bd and the one that’s caused the global pandemic can lead to greater infection rates and illness strength than either can alone.It was conducted by researchers from universities in Brazil and the U.S. who looked at infection in several frog species in Brazil’s Atlantic Forest. They chose that region because of its high amphibian biodiversity (despite being one of the most deforested ecosystems on the planet), as well as because it is the only known region in the world where multiple strains of Bd coexist and hybridize.The researchers say their results indicate frogs may face a future even more dire than anticipated as different strains of Bd spread around the world and combine into more harmful forms. They call for increasing global monitoring efforts to detect these shifts before they lead to new outbreaks. A fungus that has decimated frog populations around the world could get even deadlier, according to new research. The study found that hybridization of different types of the fungus creates strains that can cause greater mortality in frogs. And it warns that deforestation could make this impact worse.The fungus is called Batrachochytrium dendrobatidis – Bd for short – and it causes a disease called chytridiomycosis that affects a frog’s ability to absorb water and electrolytes through its skin. Scientists first started to take notice in the 1970s when frog populations in Central and South America started disappearing. By the 1990s Bd had spread around the world, likely aided by the laboratory trade in African clawed frogs and invasions of American bullfrogs. By 2007 it had been implicated in the decline or extinction of some 200 species.Today, biologists consider it one of the biggest threats to amphibians globally.Some research has offered a bit of hope for frogs, with a study published earlier this year in Science finding populations may be able to develop resistance to Bd.But a new study published last week in Scientific Reports adds another hurdle for frogs, finding that hybridization between a native strain of Bd in Brazil and the one that’s caused the global pandemic can lead to greater infection rates and illness strength than either can alone.The study was conducted by researchers from universities in Brazil and the U.S. who looked at infection in several frog species native to Brazil’s Atlantic Forest. They chose that region because of its high amphibian biodiversity (despite being one of the most deforested ecosystems on the planet) and because it’s the only known region in the world where multiple strains of Bd coexist and hybridize.Deforestation for agriculture and other development have reduced Brazil’s Atlantic Forest to less than 15 percent of its original extent. Some scientists estimate that less than 7 percent may remain.Scientists believe the Brazilian strain of Bd (Bd-Brazil) evolved along with amphibian populations there and, because of this, is not as harmful to them as the Global Pandemic Lineage (Bd-GPL). But when the team compared infection and illness rates of the two types of Bd and a third hybridized one, they found that the latter had a significantly worse impact on two of the three frog species they examined.The researchers write that this effect may be due to a phenomenon called “hybrid vigor” (also referred to as “heterosis”), by which the sudden surge in genetic diversity caused by hybridization leads to a more dramatic expression of advantageous physical traits. Take, for example, mules, which tend to be stronger (and smarter, according to at least one study) than either their horse or donkey parents. The same might be happening for Bd. Combining the genes of different strains of Bd could make a hybrid strain even stronger than Bd-GPL.Another reason why hybrid Bd may be affecting frogs so profoundly is reduced genetic diversity in the frogs themselves. The authors write the pumpkin toadlet (Brachycephalus ephippium), one of the frog species that experienced high death rates when infected with the strain, lives in isolated, patchy habitats that “may have limited its exposure to pathogens throughout its evolutionary history or lowered its immunogenetic diversity.”The pumpkin toadlet (Brachycephalus ephippium), endemic to Brazil’s Atlantic Forest, is highly susceptible to the hybrid Bd fungus, according to the new study. Photo by Gui BeckerThe study’s results appear to be already playing out in the real world, with previous research from the team finding that frog populations are declining and disappearing more quickly in the zone where the two Bd strains are known to hybridize.And they warn that deforestation “may tip the host-pathogen balance further in favor of the pathogen” as habitat loss stands to increasingly isolate frog populations, further reducing their genetic diversity, while “even the most fragmented landscapes in the Atlantic Forest” don’t seem to be a barrier to Bd.The researchers say their results indicate frogs may face a future even more dire than anticipated as different strains of Bd spread around the world and combine into more harmful forms. They call for increasing global monitoring efforts to detect these shifts before they lead to new outbreaks.“With globalization facilitating pathogen spread across continents, hybridization of chytrids might lead to new epidemic waves reducing amphibian biodiversity in both tropical and temperate regions,” said study coauthor Gui Becker, assistant professor of biological sciences at the University of Alabama.

It is mentioned that planting trees in village common lands will have negative affects socially and ecologically. There is no need to even have to agree or disagree with it, because, you also mentioned the fact that Cauvery Calling aims to plant trees only in the private lands of the farmers. So, plantation in the common lands doesn’t come into the picture.2.I don’t see that the ecologists are totally against this project, but just they they have some concerns, mainly in terms of what species of trees will be planted. And because there was no direct communication between the ecologists and Isha Foundation, it was not possible for them to address the concerns. As you seem to have spoken with an Isha spokesperson, if you could connect the concerned parties, it would be great, because I see that the ecologists are genuinely interested in making sure things are done the right way.May we all come together and make things happen.Rare Amazon bush dogs caught on camera in BoliviaCarrot1 Feba very good iniciative to be fallowed by the ranchers all overSponsored Citation: Greenspan, S.

PSG’s Aurier sentenced over police assault

first_imgThe Ivory Coast international was later included in PSG coach Unai Emery’s squad for Wednesday’s Champions League tie at Ludogorets in Bulgaria.The incident occurred on May 30 outside a Paris nightclub when Aurier was arrested and placed in police custody.The court heard that the troubled footballer refused to cooperate when asked to leave his tinted-glass Porsche Cayenne which police claimed was incorrectly parked outside the club in the early hours in an upmarket district of the French capital.Police said the situation turned violent when an agitated Aurier elbowed one of the officers in the chest, causing him to have to take a day off work.“The driver got out of the car straight away and apologised but the front passenger (Aurier) refused to show his hands,” the policeman told the court.Paris Saint-Germain’s Ivorian defender Serge Aurier in action against hosts Toulouse on September 23, 2016 © AFP/File / Pascal PavaniHe said he had to grab Aurier to make him exit the car, at which point the player elbowed him.Aurier denied the charge and was allowed to leave the court.“The club takes note of his condemnation. An appeal has been lodged at the end of the hearing by the player’s lawyer,” said a PSG statement.“Serge Aurier will continue to benefit from the presumption of innocence ahead of the appeal court’s decision.”Aurier later took to Twitter to express his “confidence in justice” and that he would await “the appeal … to express myself again”.The player, who has had recent disciplinary problems with his club, rejected the police account of the incident and said he was the victim of violence.He has filed a complaint against the police.Given his lack of remorse, the court went beyond the prosecutor’s request for a sentence of two months suspended or with community service. The sentence took into account Aurier’s four previous convictions for driving without a licence.The court also ordered him to pay 600 euros $674) in damages and interest as well as 1,500 euros in court costs.– ‘Lacked lucidity’ –He was described by the public prosecutor as having “lacked lucidity” during the incident and acted in a “puerile and immature” manner.Paris Saint-Germain’s defender Serge Aurier (C) rejects the police account of the incident and says he was the victim of violence © AFP / Patrick KovarikAurier, who said in court he earns 200,000 euros a month, was in trouble with his club last season after making derogatory comments about his then-PSG coach Laurent Blanc and other team-mates, including current Manchester United star Zlatan Ibrahimovic, on a social media video post.He was suspended by his club for five weeks but owned up to having committed “a stupid mistake”.However, when filming a video to apologise for his comments, Aurier behaved in an “indifferent” manner and needed several takes to get his apology right, according to France Football magazine.PSG owner Nasser Al-Khelaifi even yelled at him that he would “stay five hours if necessary, but you’ll do what we ask”, added the magazine.The year before, Aurier copped a three-match ban from UEFA after reacting to a PSG victory in the Champions League by posting a video on Facebook in which he called the referee a “son of a bitch”.But since returning to pre-season training in July, Aurier has impressed his bosses.“The club wants to underline the player’s professional attitude shown since his return on July 4.“At the same time, Paris Saint-Germain reaffirms our affection and respect for the forces of order and the jobs they do.”However, his court appearance comes on the back of Aurier being sent off in PSG’s 2-0 Ligue 1 defeat at Toulouse on Friday night, their second reverse of the season.0Shares0000(Visited 1 times, 1 visits today) 0Shares0000Paris Saint-Germain defender Serge Aurier (R) arrives at the Paris courthouse where he was jailed and fined for elbowing a police officer, on September 26, 2016 © AFP / Patrick KovarikPARIS, France, Sep 26 – Paris Saint-Germain defender Serge Aurier was sentenced to two months in jail by a court in Paris on Monday for assaulting a police officer.But the 23-year-old will not serve any time in prison as he is appealing his sentence which was less than one year.last_img read more
