The fate of the non-native collembolon, Hypogastrura viatica, at the southern end of its introduced range in Antarctica

first_imgInvasive species present a risk to Antarctic ecosystems by altering community structure and function. Reports of non-native invertebrates are increasing at Antarctic sites subject to tourism industry and national operator activity. Furthermore, dispersal of existing non-native species to other Antarctic sites may greatly expand their distributions and increase the spatial scale of potential impacts. Consequently, non-native species occurring near logistical hubs present an enhanced risk. The non-native Collembolon, Hypogastrura viatica, was introduced to Léonie Island, Ryder Bay, near the logistical hub of Rothera Research Station, Rothera Point, Adelaide Island, at some point before 1993, but no attempt had been made to assess the extent of its distribution in the local area. In this study, we surveyed the regularly frequented islands of Ryder Bay and Rothera Point to attempt to assess the continued presence and distribution of this species. Hypogastrura viatica was not identified amongst the 36,796 Collembola specimens extracted from 138 samples taken from the islands and Rothera Point. With no evidence of the continued presence of this non-native Collembolon in the local area, either H. viatica has become extinct or has such a restricted spatial distribution that our monitoring programme failed to detect it. In light of these results, existing local biosecurity measures will be maintained as a precautionary measure to reduce the risk of further anthropogenic dispersal of this potentially invasive Collembolon as well as of any other species imported unintentionally in future.last_img read more

Wuhan doctor at whistleblower’s hospital dies from coronavirus

first_imgFellow doctor Yi Fan showed similar symptoms, but recovered and has since been discharged from hospital.The death of their colleague Li Wenliang in February triggered a national outpouring of grief and rage against the government as he documented his final days on social media. The 34-year-old ophthalmologist was reprimanded by authorities after he warned colleagues about the virus in late December. Beijing has since named him a national martyr, but suppressed much of the dissent and criticism sparked by his death. Other medical whistleblowers at Wuhan Central Hospital — including emergency unit director Ai Fen — have told Chinese media they were punished by authorities for speaking out. China has not released a complete figure of the number of medical worker deaths from Covid-19, but at least 34 medics have been awarded posthumous honors by health authorities.In February the National Health Commission said some 3,387 health workers had been infected.  Cases have dwindled dramatically from the peak in mid-February as the country appears to have brought the outbreak largely under control.The official death toll in the country of 1.4 billion people stands at 4,634 — well below the number of fatalities in less populous nations.Wuhan Central Hospital has yet to give a formal statement on Hu’s death. In early February it said some 68 staff members had contracted coronavirus.Hu’s condition became a national concern after Chinese media showed images of him with his skin turned black due to liver damage.

Water polo defends top rank in double overtime

first_imgKatie Chin | Daily TrojanIn front of a rowdy home crowd, men’s water polo defeated the No. 7 Long Beach State 49ers 11-9 in overtime Thursday. After beating the 49ers 13-5 earlier this season, the Trojans headed into the rematch ranked No. 1 for the first time in the 2017 season. Nevertheless, the 49ers kept the game close, never trailing by more than 3 points.“That was a scary one, for sure,” senior goalie McQuin Baron said. “I didn’t like that much but it’s always good to have a game like this, play under pressure because last season we didn’t really play any overtime games or any fourth-quarter close games and this season we’ve had four or five already. So going into the back end of our season, going back to these games will really help us out.”From the start, the game was tight, with both teams held scoreless for the first six minutes. USC two-meter sophomore Matt Maier broke through and scored with 1:39 left in the first, and senior utility Bryce Hoerman tacked onto the Trojans’ lead with 37 seconds left. The 49ers were able to respond quickly in the second, tying the game by the half 3-3. The third quarter play remained close, and the Trojans entered the fourth with a slim 6-5 lead. USC added two more goals in the fourth, but with 3:29 left, Long Beach scored three unanswered goals to tie the score at 8, sending the game into overtime.“In between quarters there, overtime and everything, it was just X’s and O’s,” senior utility James Walters said. “We were talking about what we can do differently, some things that we didn’t do so well and what we were going to do on the next play. For us it’s just what’s going to happen next time.”With 4.7 seconds left in the first overtime, Maier broke through to give the Trojans a 9-8 lead. Freshman driver Marko Vavic followed with a goal early in double overtime for the Trojans. Long Beach junior defender Austin Stevenson scored with 1:15 left in the game to close the gap to 10-9, but USC senior driver Grant Stein scored with a second left in the session to seal the win for the Trojans, 11-9.With the ultimate goal of a national championship in mind, the team still has room to improve before heading into the back half of its season.“Counterattack defense needs to be better, we need to improve on that,” Baron said. “Our 6-on-5 was kind of weak today, I think on a few of them we didn’t even get a shot, which is kind of unacceptable when you have a man advantage.”With their four-game winning streak at stake, the No. 1 ranked Trojans have two days to rest before traveling to No. 8 UC Santa Barbara Saturday. “Santa Barbara, you never know,” Walters said. “Their pool, one end is shallow, the crowd is great there, it’s always a really fun environment, there’s a lot of energy there. I’m looking forward to that game, and I know the guys are. It’s always fun.”last_img read more

Southern rugby’s export boom

first_img29 June 2007Springbok captain John Smit will be playing his rugby in France for the next two years, joining what could become an exodus of top South African rugby players to Europe. Judging by similar moves by Australian and New Zealand players, the game could be in for a shake-up after the World Cup in France.Smit announced on Wednesday that he has accepted an offer to play for Cleremont Auvergne in 2008/09. Free State Cheetahs’ centre Marius Joubert is joining Smit there, while former Springbok Grant Esterhuizen is already on the club’s books.“Representing the Springboks since my debut in 2000 and also playing for my beloved Sharks was a real dream come true for me and I thoroughly enjoyed my time with them,” Smit said on the Sharks website. “However, the time has come to make a change and move on in my professional career.”Smit’s decision notwithstanding, national coach Jake White, should he remain coach of the Springboks after the World Cup, has said he would still pick the hooker to captain the Boks. “Without a doubt, John’s ability to lead a team, coupled with his strength in the scrums and accuracy in the lineout, make him special,” White said.Andy Marinos, the manager of South Africa’s national rugby teams, said Smit had consulted SA Rugby throughout the process and “we respect his decision”.More international skippersSmit might not be the only Springbok captain heading for France. Ambitious French second division side Toulon recently announced that Victor Matfield, who led South Africa against New Zealand in Durban recently, has been signed.Matfield hasn’t yet confirmed the move. The French media, however, have quoted the lock as saying he has only a few loose ends to tie up and is committed to Toulon in principle.Former All Black captain Tana Umaga is both a player and the club’s general manager. He’s been very active signing players, and apart from chasing Matfield – viewed by many as the best lineout forward in world rugby – Umaga has signed Australia’s George Gregan, the most capped player in test, former All Blacks flyhalf Andrew Mehrtens, and Anton Oliver who, like Umaga, has led New Zealand.South Africans at ToulonToulon has a good number of South African players on its books, including Daniel Muller, Nicky Smit, Charl van Vliet, Nico Breedt, Norman Jordaan and Chris Rossouw, so it appears that settling settling in wouldn’t be a problem for Matfield.The club’s most recently announced signing, prop Lawrence Sephaka, brings the number of South African players, excluding Matfield, to seven.Toulon even has a South African coaching connection, with Tim Lane, who previously coached the Cats (now Lions) in Super Rugby and served as a Springbok assistant coach, in charge.While Matfield is 30 and probably doesn’t have that many years left in his career, another Springbok star, Schalk Burger, has drawn the interest of France’s Toulouse and England’s NEC Harlequins, and he is just 24 years of age.Currency issuesNaturally, South African rugby would rather not lose a young superstar to a northern hemisphere club, but it is an uphill battle for South Africa’s provinces and the SA Rugby Union – at current exchange rates the euro is worth close to R10, while the pound is worth over R14.It would be difficult, if not impossible, for South Africa to match the money Europe can offer players of the stature of Smit, Matfield and Burger.The list of players rumoured to be heading north doesn’t end there, however, and, if the number of New Zealanders and Australians also heading in that direction after the World Cup is any indication, a lot of South Africans will be joining them.UK callingPercy Montgomery, who previously had a stint in Wales with the Newport Gwent Dragons, has been linked with Perpignan, as has Bok winger Ashwin Willemse. Gerrie Britz has already signed a three-year contract with the club.Springbok flyhalf Butch James has reportedly been approached by English club Bath, while 39-test veteran De Wet Barry recently signed a two-year contract with Harlequins.Should a large number of frontline Springboks sign contracts with French and English clubs, there could be problems for SA rugby down the line.One need only to look back on England’s recent tour of South Africa and France’s tour of New Zealand, where both touring teams were missing many top players because of club rugby commitments.In both series, the southern hemisphere teams, at full strength, recorded record margins of victory over the northern hemisphere sides. South Africa thumped England 58-10 and 55-22, while the All Blacks hammered France 42-11 and 61-10.World rugby shake-up?Increasingly, countries are selecting teams for test matches that are not their strongest line-ups, but rather selections that are used to gauge whether players are potential World Cup players or not.The rugby world could be in for a big shake-up after the World Cup in France, with more watering down of national teams a definite possibility.An exodus of South African, New Zealand and Australian players could result in a weakened Tri-Nations competition; it could even end up with the southern hemisphere powers sending out third-string teams against the northern hemisphere.When England tackled the Springboks recently, 30 top players were unavailable for selection, mostly because of club commitments. The shoe could soon be on the other foot.SA players in EuropeBelow is a list of South Africans who played club rugby in France or England this past season, or who are set to play in Europe next season (A * indicates players linked with a move to a club, ^ indicates players who have recently signed contracts).Included in the list are a number of English, French, New Zealand and Welsh rugby internationals who were born and/or grew up in South Africa.FRANCEStade FrançaisPieter de Villiers (French international), Boela du Plooy, Brian Liebenberg (French international), Frans ViljoenToulouseDaan Human, Gaffie du ToitCleremont AuvergneGrant Esterhuizen, John Smit*, Marius Joubert*PerpignanGavin Hume, Gerrie Britz*, Percy Montgomery^, Ashwin Willemse^BourgoinRudi Coetzee, Wessel JoosteMontaubanBraam ImmelmanCastresDanie Saayman, Gerhard VoslooBriveVickus Liebenberg, Johan van Zyl, Hendrik Gerber, Charl van RensburgMontpellierDrikus Hancke, Rickus LubbeBayonneRob Linde, Jacques Deen, Sam Gerber, Eduard CoetzeeNarbonneHenk Eksteen, Retief Uys, Tinus van RensburgAgenWillem Stoltz, Adri Badenhorst, Pietman van Niekerk, Conrad StoltzToulouseSchalk Burger^Toulon (Division Two)Daniel Muller, Nicky Smit, Charl van Vliet, Nico Breedt, Norman Jordaan, Chris Rossouw, Victor Matfield^ENGLANDGloucesterRudi Keil, Jake BoerSaracensCobus Visagie, Neil de KockLondon IrishMike Catt (England international), Danie Coetzee, Faan RautenbachNEC HarlequinsStuart Abbott (England international), Hal Luscombe (Wales international), Andre Vos, Schalk Burger^BathPieter Dixon, Hottie Louw, Matt Stevens (England international), Michael Claassens, Butch JamesNewcastle FalconsRussell WinterWorcester WarriorsThinus Delport, Greg Rawlinson (New Zealand international)Northampton Saints Joe van Niekerk, Geoff Appleford (England international), Pat Barnard Want to use this article in your publication or on your website?See: Using SAinfo materiallast_img read more

Endangered white pelicans venture to Vancouver Island thrilling bird watchers

first_imgVICTORIA – A rare sighting has bird watchers on Vancouver Island aflutter.American white pelicans have been spotted in several areas of the Island, from Tofino and Parksville, all the way south to a golf course in Victoria.Victoria-area naturalist Ann Nightingale says climate change may have brought the birds further west than usual but she says it’s not certain why the pelicans are suddenly interested in Vancouver Island.A colony of American white pelicans is known to breed at a site west of Williams Lake in the Chilcotin region, but it is the only breeding colony in B.C., although the birds have well-established breeding sites across the Prairies.The Environment Ministry says the white pelican has been legally designated as an endangered species in British Columbia.The migratory bird, which can winter as far south as Central and South America, is one of the largest in North America, with a wing span of up to three metres.

Mehbooba leads protest march against suspension of LoC trade

first_imgSrinagar: PDP president Mehbooba Mufti on Wednesday led a protest march of her party activists in Jammu and Kashmir’s Pulwama district against the suspension of cross-Line of Control (LoC) trade and ban on Jamaat-e-Islami (JeI). The protest march was taken out from Town Hall Pulwama to deputy commissioner’s office. Mehbooba demanded the revocation of the decision to suspend the cross-LoC trade and sought immediate release of Jammu and Kashmir Liberation Front (JKLF) chairman Mohammad Yasin Malik from custody. She also sought revocation of ban on JeI and an end to the ban on civilian traffic on Srinagar-Jammu National Highway. Malik is not in good health.

Our fight is against militants, but you should not harass their families, she told reporters.last_img read more

Samsung still has time to correct its foldable dream

first_imgNew Delhi: Just when the industry through innovation in the smartphone business had hit stagnation, Samsung wowed us with its first foldable device “Galaxy Fold,” worth a whopping $2,000. A super-premium phone that took almost a decade in the making and opens like a book when unfolded, shouted everything next-generation. However, the expectations took a beating when reports of the Galaxy Fold issues surfaced. The units given to international tech reviewers encountered display distortion and screen flickering issues, forcing the South Korean giant to postpone its launch in Hong Kong and Shanghai on April 23 and 24 respectively, and issue a recall of review units. Also Read – Swiggy now in 500 Indian cities, targets 100 more this year The big question lingers: Will the “Foldgate” make a dent in Samsung’s image like the Galaxy Note 7 with exploding batteries did in 2016? According to CyberMedia Research (CMR), the smartphone major has been mature and pragmatic enough by postponing its launch and sorting out all the issues before its general availiability. “All said, for Samsung, there is no race for first past the post with its foldable smartphone. It is more imperative for the company to focus on not delivering a flawed product, but rather ensuring highest consumer experience when the device goes on sales,” Prabhu Ram, Head, Industry Intelligence Group (IIG), CMR, told IANS. Also Read – New HP Pavilion x360 notebook with in-built Alexa in India Defending its devices just days before its roll-out, a Samsung spokesperson assured that the firm would “thoroughly inspect” the units. According to market research firm Gartner, foldable phones would make up 5 per cent of high-end phones sales by 2023 with around 30 million units. According to Faisal Kawoosa, Founder and Principal Analyst of market research firm techARC, from a technology-rich company like Samsung, “one would expect things out only after reliability of desired levels are achieved”. The Galaxy Fold is expected to be priced around Rs 1,40,790 in India. “Nevertheless, the lab and real-world conditions play differently. I don’t see it as a big issue as the product has not exchanged hands with consumers yet. They have time to correct this aberration,” Kawoosa told IANS. Some units of the Galaxy Fold, which became the first phone with a foldable OLED display, is encountering two primary issues: the foldable screen seems to have a layer of protective layer that is similar to a cheap screen film. Several units reportedly failed after the layer was taken off. Few other screens failed because the hinge exposed areas which allowed debris to get inside of the display, thus, damaging the unit. “We expect that users will use a foldable phone as they do their regular smartphone, picking it up hundreds of times a day, unfolding it sporadically and typing on its plastic screen, which may scratch quickly depending on the way it folds,” Roberta Cozza, Research Director at Gartner had earlier said. However, according to market research firm techARC, this is primarily a material issue than a design. “I think till the time it’s a plastic-based screen, the chances of such mishaps remain high. I would certainly like to see a glass display, that too from credible makers like Corning, to have a reliable foldable screen,” stressed Kawoosa. Moreover, there’s no denying that the second-generation of foldable devices would be better that the experimental and ambitious first generation iterations. “The first generation of an innovation is always experimental, and which over successive iterations achieves perfection. Let’s’face it. The Galaxy Fold was just a mistake in timing. It does not take away anything from its manufacturing capabilities,” Ram noted.last_img read more

Commentary Resilient spirit needed for Ohio State football to advance to 90

Ohio State’s game against Purdue on Saturday appeared to be over. With the Buckeyes trailing by eight points, and just two minutes and 40 seconds remaining on the game clock, OSU redshirt junior backup quarterback Kenny Guiton’s deep ball had just been intercepted by Purdue sophomore safety Landon Feichter. As it seemed the 7-0 Buckeyes were headed for their first loss of the season, many OSU football fans began their exodus from Ohio Stadium. It was hard not to give up on the Buckeyes at that point. OSU’s star quarterback, sophomore Braxton Miller, had left the game in the third quarter with a head injury. In his place, Guiton had failed to lead the Buckeyes to points on three consecutive drives. For the Buckeyes’ offense to even get another shot at tying the game, a defense that had given up 49 points to Indiana one week earlier needed to force Purdue’s offense off the field in four downs or less. If the Buckeyes were going to win, they needed a miracle. At that point, the Buckeyes showed the resilient, never-say-die attitude that first-year coach Urban Meyer has clearly instilled. The defense did exactly what it needed to do, not allowing a single first down and forcing a punt, which gave Guiton and the offense 47 seconds for one final shot at a game-tying drive. Guiton took advantage of his moment to shine. Guiton’s first pass was a 39-yard connection with sophomore wide receiver Devin Smith, which kicked off a drive that reached completion with a two-yard touchdown pass to redshirt junior wide receiver Chris Fields. Still needing two points to send the game to overtime, Guiton subsequently completed a pass to wide-open sophomore tight end Jeff Heuerman in the end zone. From there, the Buckeyes did their job again on both sides of the ball, as another Guiton-led scoring drive and a defensive stop gave the Buckeyes an improbable 29-22 victory in overtime. The Buckeyes may be 8-0, but they certainly haven’t made it easy to stay undefeated. While they have been heavily favored in most games, they have trailed in the second quarter or later in seven of eight games, and have either gone to overtime or won by three points or less in three of their four in-conference games this season. As should be expected of any team with a postseason ban and a first-year head coach, the Buckeyes have their issues, but they have displayed a knack for coming through and making the plays necessary to escape each game with victory. In games where the Buckeyes have failed to play up to their ability, as was certainly the case against Purdue, they have seemingly willed victories away from their opponents when the game is on the line. On Saturday, however, the Buckeyes will be facing a team that has shown even greater resiliency. The Buckeyes are traveling to University Park, Pa. this weekend to take on the Penn State Nittany Lions, a team that has overcome an 0-2 start to win five consecutive games. The Penn State football program was rocked within the past 12 months by the Jerry Sandusky sexual abuse scandal that cost legendary head coach Joe Paterno his job, and later had to overcome the death of Paterno and NCAA sanctions levied against the program as a result of the Sandusky scandal, all the while adjusting to a new head coach of their own in Bill O’Brien. In the first two weeks of the season, the effects of this tumult seemed to have their effect on the Nittany Lions, who suffered surprising losses to Ohio and Virginia. Since then, however, Penn State has rolled off five consecutive wins, and comes into Saturday’s matchup as a serious threat to give the Buckeyes their first loss of the season. As both teams are ineligible for postseason play, some would say they have nothing to play for, but don’t tell that to the Buckeyes or Nittany Lions. After overcoming major adversity leading into their 2012 seasons, both of these teams have taken on new identities under their new coaches, and are making their regular seasons count. Meyer’s Buckeyes are composed largely of the same personnel from the 2011 team that went 6-7, and he has reignited the winning tradition that OSU football is known for. What O’Brien has done at Penn State this season, however, is remarkable. Filling the shoes of Paterno after his 46-year career coaching PSU, and following what is arguably the worst scandal in college football history, O’Brien did not take an easy job. It will continue to be a challenge, as the Nittany Lions are in just their first year of four years of NCAA sanctioning including a postseason ban and scholarship reductions. But by bringing his no-nonsense attitude, installing an up-tempo offense and redefining the image of Penn State football, O’Brien has the Nittany Lions headed back in the right direction. On Saturday, the Nittany Lions have a chance for their first post-scandal marquee victory if they can upset the Buckeyes. Given the way PSU has rallied together and won their past five games, the Buckeyes are going to need to be on top of their game to stop that from happening. Playing an ambitious team in Beaver Stadium, the nation’s second-largest stadium, a will to win won’t be enough to remain undefeated. read more

Chris Hughton praises Dunk Duffy

first_imgBrighton & Hove Albion manager Chris Hughton has heaped praises on the club’s central defensive pairing of Shane Duffy and Lewis Dunk.The Seagulls’ success in establishing themselves in the Premier League owes a lot to their defensive capabilities, built on the reliable centre-back partnership of Dunk and Duffy.Dunk, who’s Brighton’s vice-captain became an England international last November, while Duffy is a regular with the Republic of Ireland national team.Hughton says the pair are vital members of his team and feels both players can improve by watching Liverpool’s Virgil Van Dijk play.“What Van Dijk is to Liverpool, that’s what our two are to us,” said Hughton, according to Belfast Telegraph.“We know what level he is but if I’m looking at what you would regard as two outstanding centre-halves at our level, ours are as valuable to us as what he is to them.”BRIGHTON, ENGLAND - MAY 12: Chris Hughton, Manager of Brighton and Hove Albion looks on prior to the Premier League match between Brighton & Hove Albion and Manchester City at American Express Community Stadium on May 12, 2019 in Brighton, United Kingdom. (Photo by Mike Hewitt/Getty Images)Hughton’s first words after being sacked Manuel R. Medina – May 22, 2019 The former Brighton and Hove Albion manager says he was “hugely disappointed and surprised” when he was fired from the club.“The two we have will look at the best around where they can learn from, what they can pick up from. At the moment, he (Van Dijk) is a great role model. He doesn’t miss many games, is good in both boxes and is a top, top all-around player.”Despite being four points clear at the top of the Premier League, Liverpool was beaten 2-1 by second-placed Manchester City in their last league game, before crashing out of the FA Cup courtesy of a 2-1 defeat to Wolverhampton Wanderers on Monday.Asked if the Liverpool can end their long wait for a first division title, Hughton said the Reds are favourites but “wouldn’t put money on it”.“I think they are favourites simply because of the points difference, and I think they’ve been outstanding,” he said.“But I couldn’t tell you who will win it. And certainly, I wouldn’t put money on it.”last_img read more
