Discrete taxa of saprotrophic fungi respire different ages of carbon from Antarctic soils

first_imgDifferent organic compounds have distinct residence times in soil and are degraded by specific taxaof saprotrophic fungi. It hence follows that specific fungal taxa should respire carbon of different agesfrom these compounds to the atmosphere. Here, we test whether this is the case by radiocarbon (14C)dating CO2 evolved from two gamma radiation-sterilised maritime Antarctic soils inoculated with puresingle cultures of four fungi. We show that a member of the Helotiales, which accounted for 41–56% ofall fungal sequences in the two soils, respired soil carbon that was aged up to 1,200 years BP and whichwas 350–400 years older than that respired by the other three taxa. Analyses of the enzyme profile ofthe Helotialean fungus and the fluxes and δ13C values of CO2 that it evolved suggested that its releaseof old carbon from soil was associated with efficient cellulose decomposition. Our findings supportsuggestions that increases in the ages of carbon respired from warmed soils may be caused by changesto the abundances or activities of discrete taxa of microbes, and indicate that the loss of old carbonfrom soils is driven by specific fungal taxa.last_img read more

Building a Better Cloud Starts with Getting the Best People

first_imgAs we close in on the end of our fiscal year, it’s amazing to see how much success we’ve had on the Dell Technologies Cloud team in our inaugural year. This isn’t a blog post to pat ourselves on the back or take the victory lap; it’s an acknowledgement that we still have a long way to go to achieve our goals, and that means growing the team.In this new decade, what organizations require from their cloud solutions partners has substantially changed. No one is clamoring for yet another public cloud vendor to further splinter things. No, what organizations need is a partner who can drive consistency across these disparate environments. And who better than Dell Technologies, a leader not only in infrastructure solutions, but also virtualization and cloud software, with a strong commitment to building the solutions that organizations have come to rely on so heavily.With that in mind, we launched Dell Technologies Cloud, the first set of solutions that show the path forward for Dell Technologies: Embracing Cloud Operating Models everywhere. This direction permeates every aspect of our business from engineering, to sales, to marketing. And because of this we are actively expanding our team, looking for the best and the brightest to join us on this rocketship.Here is why you should believe in us, and why this is a great organization to come into:Market Acceptance – You might be saying, “why should I select Dell Technologies versus one of the hyperscalers?” The truth is we are one of the largest and most trusted infrastructure and software companies in the world, and our launch of Dell Technologies Cloud has been praised by analysts and customers alike.Ability to Make an Impact – Since the solution is relatively new to market and we’re rapidly transforming to meet new markets and new customers’ needs across the board, we have a startup-like culture, backed with the investments only the largest companies can make.Smart and Pragmatic Leadership – We enter spaces with an obvious market need and where we hold a competitive advantage, versus getting into protracted and messy battles where either side’s success looks more like mutually assured destruction. Because of this, even during challenging economic conditions we’ve executed well and taken share.Strong Culture – I’ve spent time in many different organizations but Dell’s commitment to work/life balance and ability to foster a collaborative “one team” culture is truly unique. I can’t stress enough how amazing it is to be able to ask for help and see folks willing to support as opposed to having them say “that’s not in my KPIs.”Career Trajectory – From what I’ve observed in my almost three years here, and looking at this team specifically, we’re in a high growth area that can lead to great career growth. From my own experience I would say it’s been the most I’ve ever been rewarded for the work I’ve done.Come join us! Take on the challenge of educating an entire market that the next decade must deliver consistent experiences across all the clouds. It’s a great company to work for.Please visit the Dell Technologies career site and search for “cloud” jobs there. We have many openings including Product Marketing, Sales Enablement, Engineering, and Product Management roles that we’re actively filling.last_img read more

Cricket News 1st ODI: Kuldeep’s magic, Rohit’s grace take India to emphatic victory

first_imgNottingham: Chinaman Kuldeep Yadav bamboozled England batsmen with a mesmerizing spell before Rohit Sharma’s sublime century saw India cruise to a eight-wicket victory in the first ODI at Nottingham on Wednesday.Kuldeep’s career-best figures of 6 for 25 allowed England to only score a modest 268 on good batting conditions.The chase was a stroll in the park for as the runs were knocked off in only 40.1 overs courtesy Rohit’s (137 no off 114 balls). It was the opener’s 18th ODI hundred, which was beautifully complemented by skipper Virat Kohli (75, 82 balls) as he struck his first 50 plus score of the tour. The Kohli-Rohit duo added 177 runs in 25.1 overs to seal the issue.Once Kohli opted to field, the English script unfolded very much on similar lines with the T20 series, where things went downhill as soon as Kuldeep was introduced into the attack.None of the England batsmen were able to read him and a testimony to that was his brilliant figures of 10-0-25-6, the best ever by any chinaman bowler in the history of ODIs.He bowled an astounding 38 dot balls and not once was he hit for a boundary. This was Kuldeep’s first five-for in ODIs after he had recently achieved the same feat in T20Is during the Manchester encounter.The manner in which Kuldeep set up the match, there was no scoreboard pressure on the Indian batting line-up unlike the last ODI series, where England trampled Australia under a mountain of runs.Rohit, who always takes time to get off the blocks and then accelerate, hit 15 fours and four sixes. He completed his century with an effortless hit down the ground off leg-spinner Adil Rashid. As if to celebrate the hundred, he also hit a one-handed six off Moeen Ali.Kohli on his part hit eight boundaries and was ready to play the second fiddle during his 47th half century in ODI cricket.Earlier, Jos Buttler (53 off 51 balls) looked the most comfortable while Ben Stokes (50 off 103 balls) played a painstaking knock as Kuldeep blew away the top order after a good start. Together, they added 83 for the fifth wicket showing signs of recovery but he dismissed the two set batsmen in quick succession to bring about the home team’s downfall.Moeen Ali (24) and Adil Rashid (22) added a few quick runs ro help England cross the 250-run mark before they were all out in the final over with a delivery left.That Kuldeep was singularly responsible for England’s batting collapse was evident more so because the next best figures were 2 for 70 in 9.5 overs by Umesh Yadav.Even Kuldeep’s spin twin Yuzvendra Chahal (1/51 in 10 overs) was not exactly economical.The match started with both Jason Roy (38) and Jonny Bairstow (38) launching into Yadav and debutant Siddarth Kaul (0/62 in 10 overs) with a flurry of boundaries.They added 73 for the opening stand before a wrong execution of reverse sweep brought about Roy’s downfall.Kuldeep was not afraid to flight the ball and dipped viciously having the batsmen in two minds. Some played with the turn and some tried against the turn—both with dismal outcomes.At the start of the 13th over, Joe Root (3) was completely befuddled by a ripping leg break and was trapped lbw. Four balls later, Bairstow was trapped lbw via DRS, failing to read the googly.England had collapsed to 82 for 3, losing three wickets for nine runs in the space of 16 balls. Soon, it became 105-4 as Chahal got into the mix of things with Eoin Morgan (19) caught at cover.This brought Stokes and Buttler together at the crease, and they put on 93 runs for the fifth wicket. Losing too many wickets meant that they had to take time and rebuild the innings, with Stokes in particular scoring at a very low strike-rate.Buttler though continued his rich vein of form and smacked his 18th ODI half-century off 45 balls. In doing so, he put on 50 off 59 balls with Stokes, yet it was only a part-recovery for England.Throughout his innings, Buttler batted with most ease against both pace and spin, and hit five boundaries in all. It appeared as if he was preparing for an assault in the death overs, but Kuldeep sucked out any momentum that he had built.
