Vegetation cover regulates the quantity, quality and temporal dynamics of dissolved organic carbon and nitrogen in Antarctic soils

Populations of the two native Antarctic vascular plant species (Deschampsia antarctica and Colobanthus quitensis) have expanded rapidly in recent decades, yet little is known about the effects of these expansions on soil nutrient cycling. We measured the concentrations of dissolved organic carbon (DOC) and nitrogen (DON), amino acids and inorganic N in soils under these two vascular plant species, and under mosses and lichens, over a growing season at Signy Island in the maritime Antarctic. We recorded higher concentrations of nitrate, total dissolved nitrogen, DOC, DON and free amino acids in soil under D. antarctica and C. quitensis than in lichen or moss dominated soils. Each vegetation cover gave a unique profile of individual free amino acids in soil solution. Significant interactions between soil type and time were found for free amino acid concentrations and C/N ratios, indicating that vascular plants significantly change the temporal dynamics of N mineralization and immobilization. We conclude that D. antarctica and C. quitensis exert a significant influence over C and N cycling in the maritime Antarctic, and that their recent population expansion will have led to significant changes in the amount, type and rate of organic C and N cycling in soil. read more

(AP Photo/Gregorio Borgia)ROME — Serena Williams looked sharper than in her previous match two months ago as she opened her clay-court season with a routine 6-4, 6-2 win over Swedish qualifier Rebecca Peterson on Monday.Next up at the Italian Open: Sister Venus Williams in the siblings’ first meeting on European clay in nearly 17 years.ADVERTISEMENT Don’t miss out on the latest news and information. Serena fell behind 3-1 in the first set but then began to take control with her baseline power on a windy day at the Foro Italico.When Serena ran down a passing attempt from Peterson and replied with a cross-court winner to break for 5-2 in the second set, she let out a scream and bent over as she pumped both of her fists.In the final game, Serena served two aces and saved two break points before closing out the first-round match.Serena finished with 28 winners to Peterson’s eight, and committed only two more unforced errors than the 58th-ranked Swede, 22-20.Serena was playing for the first time since withdrawing ahead of her third-round match in Miami because of a left knee injury. The last time Serena played in Rome was in 2016 when she won the last of her four Italian Open trophies.Serena is playing only her fourth tournament of the season and was unable to finish her last two due to physical ailments.“I haven’t been able to train or practice a lot. I was out much longer than I expected,” Serena said. “But I did everything I could to stay fit and to keep my cardio up.

Auger-Aliassime struggled with his serve, hitting seven double-faults to Coric’s one.Also, Karen Khachanov overcame a partisan crowd to beat Italian wild card Lorenzo Sonego 6-3, 6-7 (1), 6-3; while last year’s French Open semifinalist Marco Cecchinato was inspired by the home fans to beat Alex Di Minaur 4-6, 6-3, 6-1.Spanish qualifier Albert Ramos-Vinolas eliminated Gael Monfils 6-3, 6-1; and Denis Shapovalov beat Pablo Carreno Busta 6-3, 7-6 (5). “It doesn’t change at all. We’re just as fierce, Venus is just as fierce,” Serena said. “We both really want to get some match play. We’ll both do the best that we can.Serena leads the career series 18-12.“I know that she’s going to play really well and compete really well,” Venus said. “That’s a given.”In March at the Miami Open, Serena needed three sets to beat Peterson.“It’s been a while. I haven’t played a ton of matches this year,” Serena said. “Not my choice, just by force. I really, really actually desperately wanted to be on the tour and to be playing. It felt good to finally be back out.

Inguinal hernia repair- series

first_imgNormal anatomyA hernia occurs when part of an organ protrudes through a weak point or tear in the thin muscular wall that holds the abdominal organs in place.IndicationsHernia repair may be recommended for:large bulges through a small hole (increased risk of incarceration and strangulation)painful hernia Inguinal hernia repair is indicated when the bulge through the inguinal canal is large or painful.ProcedureWhile the patient is sleepy (sedated) and pain-free (local anesthesia or spinal anesthesia) or deep asleep and pain-free (general anesthesia), an incision is made over the hernia. The bulging tissue or organ is replaced inside the muscle wall, the muscle tissue is repaired, and the skin is closed.AftercareMoving and walking are recommended the day of surgery. Small children require no restrictions following routine hernia repair. Older children should avoid body contact sports for at least 3 weeks. The hernia repair is not at risk, but a blow to the incision could burst the skin closure. Expect complete recovery from surgery in about 2 to 4 weeks. Avoid heavy lifting or straining for several weeks after surgery. Avoid tub baths for at least 5 days after the operation, because soaking will separate the skin tapes and the wound could break open. Sponge bathing for infants and showering for older children are permitted the day after surgery. The wound tapes should be carefully patted dry after showering.Review Date:12/10/2012Reviewed By:Robert A.

D’Arnaud, Mets, Clip Rangers, 6-5

first_imgNEW YORK — It certainly appears that trip to Las Vegas turned Travis d’Arnaud into a much more confident hitter.The rookie catcher snapped an eighth-inning tie with a two-run double, and the New York Mets overcame an early injury to starter Jonathon Niese, beating the skidding Texas Rangers 6-5 July 4th to stop a four-game slide.“Felt really good,” d’Arnaud said. “It’s a big win for us to start the homestand.”Lucas Duda hit a two-run homer off Yu Darvish, and the Mets opened a 10-game homestand with their second victory in nine games. An angry Niese left in the first with a bruised lower back after he was hit by Alex Rios’ line drive. X-rays were negative, the team said.Star third baseman David Wright missed his seventh straight game with a sore left shoulder, but fill-in Eric Campbell had three hits and an RBI for New York. Carlos Torres, pressed into long relief when Niese was injured, gave up two runs in 4 2-3 valuable innings.“Nobody expects stuff like that to happen. It does. This is baseball,” Torres said. “Whoever they call down for, they step up and go out there and go do their job.”Shin-Soo Choo hit a leadoff homer, and Adrian Beltre also went deep for the Rangers, who have dropped six in a row and 14-of-16. Their 10-game losing streak on the road is the club’s longest since a 12-game skid in 2003.“One day the pitching is really good, and one day the offense isn’t helping,” Choo said. “Right now, everything bad is coming together at the same time.”Bobby Abreu drew a leadoff walk from Aaron Poreda (2-1) in the eighth and Campbell singled off Jason Frasor with one out before d’Arnaud sent a drive up the alley in right-center.Batting .180 when he was sent to Triple-A Las Vegas in early June, d’Arnaud quickly went on a power-hitting tear in the Pacific Coast League. Brought back to the big leagues, he is hitting .303 with six RBIs in nine games since he was recalled.“I just try to keep my mind at ease and keep everything simple and not overstress myself, and that’s been paying off,” d’Arnaud said.Jenrry Mejia (5-3) retired Rios with two runners in scoring position to end the eighth. Mejia allowed an RBI single by Adam Rosales in the ninth before retiring pinch-hitter Robinson Chirinos on a tricky popup to finish a plodding game on Fireworks Night that took 4 hours, 8 minutes.Darvish, pushed back a day because of rain July 3 in Baltimore, entered with dominant stats against NL teams. But he was off in this one, allowing four runs and five hits in five innings.“He was a little erratic with his command, but I thought he did a good job of righting the ship there in the last three innings,” Rangers manager Ron Washington said.Choo hit his 13th career leadoff homer, second this season, on Niese’s third pitch.Moments later, Rios’ drive nailed Niese on the left side of his lower back. He recovered in time to get Rios at first base — the only out he got — before Manager Terry Collins, pitching coach Dan Warthen and trainer Ray Ramirez came out to check on the left-hander.Niese repeatedly told Collins he was fine, but was removed without trying a warmup pitch. Torres was given all the time he needed to get loose. “It was precaution more than anything,” Collins said.Niese fired his glove against the dugout wall and knocked over a bucket of bubble gum before disappearing down the tunnel.The team’s most reliable starter this season, Niese was done after 12 pitches. He has gone 21 straight starts without allowing more than three earned runs — the longest active streak in the majors.“There’s not much to say other than I’m fine. I didn’t want to be taken out. I just felt like I was cheated there a little bit,” Niese said.Elvis Andrus had his second consecutive three-hit game for the Rangers. Darvish doubled to the left-center fence for his second hit in 11 major league at-bats — the first for extra bases.(MIKE FITZPATRICK, AP Sports Writer)TweetPinShare0 Shareslast_img read more

Bourdains TV show apologizes for using offensive nickname for Newfoundlanders

first_imgST. JOHN’S, N.L. – Celebrity chef Anthony Bourdain’s TV show has apologized for calling Newfoundlanders by a diminutive nickname many find offensive.The Twitter account for CNN’s “Parts Unknown” used the term “Newfie” in a now-deleted tweet promoting this Sunday’s hotly anticipated episode on Newfoundland and Labrador.The official “Parts Unknown” account shared an article with Newfoundland-related books and local slang, saying “Embrace the Newfies as they are.”Users were quick to jump on the use of a term that’s considered derogatory, with origins implying Newfoundlanders are unintelligent and lazy.One man tweeted that “a fair portion of Newfoundlanders find the term ‘Newfie’ offensive” and said it was hard to understand why they used it “in an otherwise excellent article.”“Ah, you had me until you called me a Newfie. I find it an derogatory term,” another Twitter user said.User @staggcrystal wrote: “Come on CNN. It is Newfoundlanders.”Even as other Newfoundlanders said they didn’t find the term offensive, Seamus O’Regan, a St. John’s MP and the federal minister of veterans affairs, tweeted simply: “We don’t like it.”Late Thursday afternoon, the show acknowledged the criticism on Twitter, offered an apology and appeared to delete the original tweet.“We regret our use of the word ‘Newfie’ to describe the people of Newfoundland. We apologize for any offence and will stick to Newfoundlanders going forward,” it said.A little later, it added: “Tweets on this account are not written or reviewed by Anthony Bourdain. Once again we apologize.”James Baker of McMaster University in Hamilton, Ont., published a research paper last year on the history of the term, and its perception among post-secondary students in Newfoundland. He found that the results were a “mixed bag,” but people were quick to notice when the term was used in a derogatory way — especially on social media.“When you have someone who’s not a Newfoundlander uses it, people tend to pay much more attention to it, especially someone as famous as Anthony Bourdain,” said Baker.But Baker says most Americans, including Bourdain, likely wouldn’t pick up on the nuance behind the term, which has been compared to derogatory terms for other ethnic groups, like using “Polack” to refer to someone of Polish heritage.Baker added that while coverage of the province in American media can be fraught with cultural misunderstandings, interest in Newfoundland from outsiders can be seen as a positive, inviting potential visitors in the future.“Anything that paints the province in a positive light is a great opportunity for tourism.”Paul De Decker, a linguistics professor at Memorial University of Newfoundland, says the term “runs a gambit” when discussed in his classes. Some students see it as a “badge of honour” or an endearing term, while others think it’s inappropriate, especially from people who aren’t from the island.But De Decker sees potential for linguistic change with new audiences like American “Parts Unknown” viewers, who are likely unaware of the term’s history, or the stereotype of Newfoundland as an economically disadvantaged province.“They see it [Newfoundland] for how Anthony Bourdain has portrayed it,” said De Decker. “They may not take away the same meaning that Canadians and Newfoundlanders have understood the term in the past. To them there might be nothing but positive associations with the term.”“It would be great if we’re now at the time, and maybe this is one episode, one media outlet, where the term can take on what we call amelioration — it takes on a positive aspect.”The celebrity chef visited the province last fall, dining with local chefs on delicacies from moose meat to authentic fish and chips.Bourdain also visited the French island of St. Pierre off the coast of Newfoundland, and embarked on cod fishing and moose hunting excursions.Bourdain’s Instagram posts, including a photo of himself enjoying a seaside dinner in front of a bearskin rug with the caption “#newfoundland,” generated local excitement at the time.Jeremy Charles, head chef behind Raymond’s in downtown St. John’s, hosted Bourdain on his visit, serving up menu items and showing off the province’s splendours.Jeremy Bonia, manager of Raymond’s, reflected positively on Bourdain’s visit, saying the chef himself never used the term in his writing or appearances on the show.Bonia said the restaurant has already received emails from potential international guests who heard about Raymond’s through early coverage on “Parts Unknown,” and expects that interest to grow after the episode airs.“At the end of the day, you’re always gonna have people not happy with something, or use the wrong word,” said Bonia. “Any time Newfoundland gets showcased internationally like this, it makes everybody really proud.”As the airdate approaches, other locals are expressing their excitement for the showcase of Newfoundland’s food and culture.Said Twitter user @mrsmaris: “All of Canada will be watching. No, seriously.”last_img read more
