Fatty acid signature analysis from the milk of Antarctic fur seals and Southern elephant seals from South Georgia:implications for diet determination

first_imgFatty acid signature analysis (FASA) makes use of specific fatty acids, as well as entire profiles, to study dietary relationships at different trophic levels. Previously, FASA has been used in marine ecosystems in which diet determination by more direct methods is difficult and sometimes misleading. This study examined fatty acid profiles in milk from 2 species of pinniped from the Southern Ocean that were expected to have highly contrasting diets. Milk samples were collected from Antarctic fur seals Arctocephalus gazella in 3 consecutive years, from 1991 to 1993 (n = 72), and from Southern elephant seals Mirounga leonina in 1988 (n = 53) at South Georgia. Lipids were extracted and fatty acid profiles determined by temperature-programmed gas chromatography. Possible prey species collected from waters around South Georgia were also analysed. Cluster analysis as well as classification and regression trees (CART) indicated that profiles from fur seals and elephant seals were significantly different. Southern elephant seal data could be distinguished from Antarctic fur seals by lower levels of the fatty acids 16:4 n1, 18:2 n6, 18:4 n3, 18:4 n1 and 20:5 n3 and by higher levels of 18:0, 18:1 n9/ n11 (i.e. 18:1 n9 co-eluting with 18:1 n11) and 20:1 n9. Fatty acid signatures from the milk of Antarctic fur seals were closest to krill and fish species that were also known to feed on krill. Southern elephant seal fatty acid profiles were closest to species that are not known as krill predators such as larger notothenids and myctophids. The fatty acid profiles of Antarctic fur seals showed considerable inter- and intra-annual variability, which was congruent with diet variability detected using scat analyses. Southern elephant seals showed little variation in profile through lactation. In contrast to previous diet analyses based on examination of stomach contents, the results from FASA were consistent with a fish-based diet for Southern elephant seals.last_img read more

I want every SOEs [ministry] project to be done this way,” said the minister.In addition to developing Benoa Harbor for tourism, Pelindo III is constructing a designated venue for the Melasti ritual, a Hindu-Balinese purification ritual for cleansing and recharging the spiritual energy of sacred temple objects.Topics : The State-Owned Enterprises (SOEs) Ministry plans to develop Benoa Harbor, through state-owned port operator PT Pelindo III, into the archipelago’s hub port for cruise liners to attract more tourists.The government is intent on developing the harbor as a tourism gateway for cruises as well as new destinations in Bali and other maritime destinations in the country, SOEs Minister Erick Thohir said in a written statement on Friday, following a coordination meeting in Bali on the Benoa Maritime Tourism Hub development project.“By holding a coordination meeting and visiting the port, related stakeholders will realize the obstacles Pelindo III will face [in developing the harborside], and what kind of support should be provided for the project,” said Erick.last_img read more

Harrington on track despite wobble

first_imgThree-time major winner Padraig Harrington was left to rue missed opportunities despite keeping his faint hopes of qualifying for next week’s US Masters alive. Open champion Mickelson had been a doubt for the event with a pulled muscle which forced him out of the Valero Texas Open last week, but the left-hander showed no ill effects. Mickelson believes receiving treatment within 30 minutes of his withdrawal could have proved vital, adding: “I travel with a light therapy machine, and I got on it right away. “I think that made a world of difference as far as expediting the healing process to where it doesn’t hurt any more. It just feels sore like I was working out, as opposed to kind of a painful experience. “I’m surprised because I was worried when it happened about the Masters. I was certainly worried about Houston, but it healed a lot quicker. I felt great today. I didn’t feel any pain or discomfort and didn’t even think about it.” On a day when 96 of the 144-strong field broke par, Sergio Garcia was the top European player with a five-under 67 matched by former Masters champion Charl Schwartzel, while Ernie Els returned a 68. Sweden’s Henrik Stenson, who can replace the injured Tiger Woods as world number one with a victory in Houston, returned a 71, while former world number one Rory McIlroy finished two under. McIlroy was three under after eight holes but missed from 10 feet for birdie on the 10th and then three-putted the 11th from long range. Another shot looked set to disappear when he found the water in trying to drive the green on the short par-four 12th, but a superb pitch ensured he saved par and an excellent bunker shot on the par-five 13th set up a birdie. However, the two-time major winner was unable to scramble for par on the 14th and had to settle for an opening 70. McIlroy wrote on Twitter: “Solid, if unspectacular start here in Houston. Really happy with my form from tee to green… Hole a few more putts and I’ll be right there!” Harrington dropped a shot on the next after failing to get up and down from a greenside bunker but quickly made amends with birdies on the 17th and 18th to reach the turn in 33. A three-putt bogey on the third halted the former Ryder Cup star’s momentum, but birdies on the fourth and sixth had him high on the leaderboard before a disappointing bogey on the ninth, his final hole. “The round itself was okay but I should have scored better as I had birdie chances at nearly every hole and felt I should have finished six or seven under,” Harrington told www.golfbytourmiss.com “Everyone has been making out this is a big week for me but then the past few weeks have been big weeks for me. Yes, there is a bit of an inevitability about this week but that’s all that changed. “But while I know it is my last chance to get into the Masters I am not trying to do anything different, and it’s not like I have a secret for good golf to keep for a week like this. “A three under par start is always okay but what I am ruing is that it could have been easily six or seven under par and I would be in a better position going forward.” At three under par, Harrington – whose last victory on a major tour came in the 2008 US PGA Championship – was four shots behind clubhouse leaders Charley Hoffmann and Bill Haas, Haas playing his last six holes in five under par with an eagle and three birdies. Former US PGA champion Keegan Bradley was among a large group a shot behind on six under, while Bradley’s playing partners Webb Simpson and Phil Mickelson were also off to a good start. The pair returned flawless rounds of 68 which meant the group were a combined 14 under par without a single bogey between them. Harrington has to win the Shell Houston Open to avoid missing out on a trip to Augusta for the first time since 1999 and got off to an encouraging start with an opening 69 at the Golf Club of Houston. The 42-year-old Dubliner started on the 10th and holed from eight feet for an opening birdie before picking up another shot on the par-five 13th. Press Associationlast_img read more

Syracuse’s 2nd-line midfield shines once again in 15-9 win over Hobart

first_imgGENEVA, N.Y. — After Syracuse’s victory over Hobart on Saturday, SU head coach John Desko confirmed that right now his team doesn’t have a starting midfield unit.It has two.“I’m not so sure we call one our first line or second line right now,” Desko said. “Call them ‘Orange’ and ‘Blue.’ Whatever you want to call them, they’re playing great at the right time of the year.”Just like it did in Syracuse’s dramatic, double-overtime win over No. 6 North Carolina last weekend, the reserve midfield unit of Billy Ward, Nicky Galasso and Derek Maltz played more possessions than the starting unit of Hakeem Lecky, Scott Loy and Henry Schoonmaker against the Statesmen.Ward and Galasso each scored a crucial fourth-quarter goal, and the No. 4 Orange (9-3, 2-3 Atlantic Coast) beat Hobart (4-8, 3-2 Northeast) 15-9 at Boswell Field in Geneva, N.Y.AdvertisementThis is placeholder text“It’s terrifying,” Hobart head coach Greg Raymond said. “You look at the first midfield and you look at the second midfield and you’ve got to have the same game plan set for all those guys.”Ward finished with two goals and two assists on four shots, while Galasso finished with a goal and an assist on three shots. The six points from Ward and Galasso tripled the combined two points from the starting unit — a goal from Lecky and an assist from Schoonmaker.It’s been a stellar stretch for the Ward-Galasso-Maltz unit. Ward scored the double-overtime game-winner to propel the Orange into the ACC tournament, and Galasso scored midway through the fourth quarter against UNC to give the Orange a 9-8 lead — its first of the day.While on Saturday against Hobart, the stage belonged to attacks Randy Staats and Kevin Rice — who combined for nine goals — it was once again Ward and Galasso who stepped up in crunch time.Ward buried home a pass from Galasso three minutes into the fourth quarter to give the Orange a 10-8 lead. The goal came in the middle of a 5-0 Syracuse run in which the Orange went from trailing 8-7 to leading 12-8.It was Galasso who scored SU’s 12th goal with 9:22 left in the game, an unassisted rifle from 15 yards out. The Orange had trailed 6-2 midway through the second quarter, but Galasso’s goal completed an eight-goal swing.Ward then put the game out of reach, scoring an unassisted goal to give the Orange a 13-9 lead with 3:43 remaining.With Staats’ stellar play to start the season earning him a starting spot with the first-line attack, Maltz has slid down to the second-line midfield, where he has meshed well with Ward and Galasso — former attacks themselves.“Nicky and Derek are so easy to play with, they’ve both got their heads up,” Ward said. “I’ve been playing with Derek since we came in freshman year, and Nicky’s really come in and gelled well. We kind of joke around, we’ve got six attackmen out there when we’re in there.”Desko said that balance is the key. With the ACC tournament coming next weekend — the Orange will play Duke at PPL Park in Chester, Pa., on Friday — Desko said it’s a positive that all of SU’s units see the field to keep themselves fresh.With Hobart starting goalkeeper Peter Zonino ruled out for Saturday’s game with a head injury, freshman Jackson Brown, who had just played eight minutes all year, started in the cage.In his first collegiate game, the firepower of Syracuse was too much to handle.Said Raymond: “The depth was a concern. You always go into a ‘Cuse game knowing that everybody that’s on the field, all six guys playing offense at once, are great offensive players.” Comments Published on April 19, 2014 at 8:54 pm Contact Josh: [email protected] Facebook Twitter Google+last_img read more
