The role of particle associated microbes in remineralisation of faecal pellets in the upper mesopelagic of the Scotia Sea, Antarctica

first_imgFecal pellets (FP) are a key component of the biological carbon pump, as they can, under some circumstances, efficiently transfer carbon to depth. Like other forms of particulate organic carbon (POC), they can be remineralized in the ocean interior (particularly in the upper 200 m), or alternatively they can be preserved in the sediments. The controls on the attenuation of FP flux with depth are not fully understood, in particular, the relative contributions of zooplankton fragmentation and microbial/zooplankton respiration to FP loss. Collection of sinking particles using Marine Snow Catchers at three ecologically contrasting sites in the Scotia Sea, Antarctica, revealed large differences in POC flux composition (5–96% FP) and flux attenuation despite similar temperatures. To determine the importance of microbial respiration on FP loss in the upper mesopelagic, we made the first ever measurements of small scale oxygen gradients through the boundary layer at the interface of krill FP collected from the Scotia Sea. Estimated carbon-specific respiration rates of microbes within FP (0.010–0.065 d−1) were too low to account for the observed large decreases in FP flux over the upper 200 m. Therefore, the observed rapid declines in downward FP flux in the upper mesopelagic are more likely to be caused by zooplankton, through coprophagy, coprorhexy, and coprochaly. Microbial respiration is likely to be more important in regions of higher temperatures, and at times of the year, or in depths of the ocean, where zooplankton abundances are low and therefore grazing and fragmentation processes are reduced.last_img read more

Inside Marketing: Weighing in on web design

first_imgThe ultimate test of a website is how well it meets users’ expectations, but it’s not easy to find out what members like and don’t like about your online portal. Two credit unions gathered member input via a simple pop-up feedback system to help guide their website redesign.$135 million Duke University Federal Credit Union used HappyOrNot Web Smileys panel to encourage members to rate selected web pages and content by clicking on a smiling, neutral or sad face and supplying additional comments if they’d like.“With our current website, our goal was to provide as much information as possible,” says CUES member Daniel Berry, CCE, CEO of the Durham, N.C., credit union. “What we’re learning is if it takes more than two or three clicks, members prefer to gather information in a phone call. As a result of feedback from members, our new website design will be simpler and more intuitive, with less information.” continue reading » 29SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblrlast_img read more

Solskjaer makes instant impact, Pogba shines

first_img– Rashford gives United perfect start –It was Pogba who was felled on the edge of the Cardiff area early on and he stepped over the ball for Rashford to take aim with a dipping effort that deceived home goalkeeper Neil Etheridge and nestled in his bottom left-hand corner.Solskjaer won only three of his 18 Premier League games in charge of Cardiff during an ill-fated spell that ended with relegation in 2014.But a winning return to Wales rarely looked in doubt thereafter as the visiting fans enthusiastically chanted the Norwegian’s name throughout.The travelling hordes were enjoying their side moving the ball around with a speed and accuracy more reminiscent of Solskjaer’s days as a player at Old Trafford when United dominated English football.Pogba was at the heart of it and his intelligent pass picked out Herrera, whose shot flicked off Greg Cunningham to loop over the helpless Etheridge.If Solskjaer’s side were fortunate then, it was Cardiff who got a break nine minutes later when the assistant referee adjudged Rashford to have handled rather than control the ball with his shoulder inside the area.Camarasa’s perfectly-taken penalty could have sparked a collapse for a team short on confidence in recent times.Instead, United responded resoundingly with a fantastic team goal as a quick interchange of passes between Pogba and Lingard freed Martial to score his ninth goal of the season.Lingard took responsibility from the spot just before the hour mark after another soft penalty was awarded for a foul by Sol Bamba on the England international.And the England international was the beneficiary of another defence-splitting pass from Pogba a minute from time as he rounded Etheridge and slotted into an empty net.Share on: WhatsApp Cardiff, United Kingdom | AFP | Ole Gunnar Solskjaer made an instant impact as Manchester United caretaker manager with Paul Pogba to the fore in a transformed performance from the final days of Jose Mourinho’s reign in a 5-1 thumping of Cardiff on Saturday.Solskjaer has been put in charge until the end of the season after Mourinho was sacked on Tuesday and could not have asked for a better start in the Welsh capital thanks to Marcus Rashford’s third-minute free-kick.The visitors also had a slice of fortune when Ander Herrera’s strike deflected in to double their advantage.But United shrugged off Victor Camarasa’s penalty, awarded for a dubious handball call on Rashford, with the sort of free-flowing play that appeared so scarcely under Mourinho as Anthony Martial started and finished a fine move also including Pogba and Jesse Lingard.And Lingard struck twice more in the second half to secure United’s biggest win of the season so far. As well as getting Solskjaer off to a flying start, victory also sees United crucially close the gap on the Premier League top four to eight points thanks to Chelsea’s 1-0 home defeat by Leicester earlier in the day.Pogba was forced to watch the full 90 minutes from the bench last weekend as Liverpool inflicted the final blow to Mourinho’s time in charge with a 3-1 win that left United 19 points off the top after just 17 games.The French World Cup-winner was restored from the start for the first time in four league games and looked far more like the player United splashed a then world-record £89 million ($113 million) on in 2016 than the one that clashed with his former boss off the field and disappointed on it for much of the past two seasons.last_img read more

TALAMO & CALLAGHAN TEAM WITH LONGSHOT DIVINA COMEDIA TO WIN $75,000 SOUTHERN TRUCE STAKES BY 1 ¾ LENGTHS AS FRENCH-BRED MARE COVERS 1 1/16 MILES IN 1:42.89

first_imgARCADIA, Calif. (July 3, 2016)–A close fourth into the first turn behind a three-horse scramble that included favored Living The Life, Belle Hill and Gloryzapper, longshot Divina Comedia sat a close fourth down the backside, overtook Living The Life three furlongs out, wheeled three-wide turning for home and prevailed by 1 ¾ lengths under Joe Talamo in Sunday’s $75,000 Southern Truce Stakes at Santa Anita. Trained by Simon Callaghan, Divina Comedia got a mile and a sixteenth in 1:42.89.“We had an absolutely perfect trip today,” said Talamo. “It was a great set up. Those two fillies (Gloryzapper and Belle Hill) went head and head the whole way and they went fairly quickly, so the set up was in our favor. My mare was all heart down the lane.”Fifth, beaten 7 ¾ lengths by the mighty Beholder in the Grade I Vanity Mile here on June 4, French-bred Divina Comedia was off at 16-1 in a field of seven older fillies and mares and paid $35.00, $12.40 and $7.00.Owned by Marsha Naify, Divina Comedia notched her first stakes win and her fourth victory overall from 18 starts. With the winner’s share of $47,100, she increased her earnings to $218,272.“Joe took care of her in her last race against Beholder because he knew what a tough spot that was,” said Carlos Santamaria, assistant to Callaghan. “She came out of that race great and she was ready to go today.”Caught three-wide into the first turn, Gloryzapper took a narrow half length advantage on Belle Hill when the two of them straightened out down the backside, remained two off the fence into and around the far turn and just held the place by a head over a fast finishing Show Stealer.Ridden by Rafael Bejarano, Gloryzapper was the second choice in the wagering and paid $4.20 and $3.00.Ridden by Tyler Baze, Show Stealer rallied from well off the pace to finish third, 3 ½ lengths clear of Moyo Honey. Off at 15-1, Show Stealer paid $4.80 to show.Off at 8-5, Living The Life fell out of contention quickly on the far turn and was eased.Fractions on the race were 23.01, 46.50, 1:11.00 and 1:36.37.First post time for a nine-race card on Independence Day, Monday, is at 1:30 p.m. Admission gates open at 11:30 a.m.last_img read more
