RIYADH: The King Abdullah University of Science and Technology, in collaboration with scientists from the Swiss Federal Technology Institute of Lausanne, has conducted an unprecedented, in-depth study on microbiomes — microorganisms that live symbiotically with humans or other organisms — in glacier-fed streams.

These streams, originating from glaciers atop the Earth’s highest mountains, harbor a wealth of unique microorganisms.

The research team collected and analyzed samples from 170 glacier-fed streams over five years across regions including New Zealand, the Himalayas, the Russian Caucasus, the Tien Shan and Pamir Mountains, the European Alps, the Scandinavian Alps, Greenland, Alaska, the Rwenzori Mountains in Uganda, and the Ecuadorian and Chilean Andes, the Saudi Press Agency reported.

The findings, published in the renowned scientific journal Nature, represent the first global reference for microbiomes in glacier-fed streams.

These streams, which are among the most extreme natural freshwater ecosystems in the world, are located at mountain summits and are characterized by near-freezing temperatures and low nutrient levels.

They also serve as the origin for many of the world’s largest rivers, functioning as vital water reservoirs for the planet.

KAUST researcher Dr. Ramona Marasco emphasized that glacier-fed streams were highly vulnerable to climate change. 

She spoke of the importance of establishing a baseline for their microbiomes to better understand the rate of ecological change, while highlighting KAUST’s extensive genetic sequencing efforts, which have significantly contributed to creating a comprehensive picture of these endangered microbiomes.

The researchers successfully developed the first global atlas of microorganisms in glacier-fed streams.

Their work revealed that these streams harbor a unique microbiome distinct from other cryospheric systems, such as glaciers, frozen soils, and ice-covered lakes.

About half of the bacterial species in these streams are endemic to specific mountain ranges. The scientists attribute this phenomenon to the geographical isolation of mountain ranges, similar to islands, and to the powerful natural selection exerted by the harsh conditions in glacier-fed streams.
 

ABU DHABI: Continental Europe, led by captain Francesco Molinari, begin their defense of the Team Cup against Great Britain & Ireland at Abu Dhabi Golf Resort on Friday.
The Italian, who became the first golfer from his country to become a major champion when he triumphed at The Open in 2019, was in charge when the Europeans claimed a 14½-10½ victory over GB&I, captained by Tommy Fleetwood, at the inaugural event (then called the Hero Cup) in 2023, personally contributing three-and-a-half points to the cause.
This time, Molinari is facing face off against fellow major champion, and Ryder Cup teammate, Justin Rose, who is captaining the opposition in an event that serves as an important part of Europe’s Ryder Cup preparations ahead of this year’s contest at Bethpage in New York in September.
The members of the two, 10-man Team Cup squads boast a combined total of 69 DP World Tour titles between them, and include four Ryder Cup players: Molinari, Rose, Fleetwood and Tyrrell Hatton.
“I think that the experience from two years ago is going to come in handy,” Molinari said. “I think a lot of the stuff that we did worked. I think obviously we were lucky to get the support from my brother and the other past Ryder Cup captains.”
Rose said of his role as captain: “It’s an honor, first and foremost. I think it’s been something that’s sort of been on my mind. Because, obviously, sometimes when you play as a player, you’re obviously preparing all the time for tournaments that come up but when you have something like this looming large, you start thinking about it months in advance.”
The Team Cup is a matchplay contest that tees off on Friday with a fourballs session, is followed on Saturday by two sessions of foursomes, and concludes with singles on Sunday. Every player competes in each of the sessions.
Rose will be in action in the first match on the opening day alongside five-time DP World Tour winner Matt Wallace. They will take on the French pair of Romain Langasque, who won the Amateur Championship in 2015, and Matthieu Pavon, who last season became the first Frenchman for more than 100 years to win on the PGA Tour.
Five-time DP World Tour winner Rasmus Hojgaard, who missed the 2023 event as a result of injury, will partner last year’s Challenge Tour Road to Mallorca Rankings winner Rasmus Neergaard-Petersen against the English pair of Laurie Canter and Jordan Smith.
Alongside the action on the course, there will be a host of activities and events throughout the three days of the event for fans to enjoy. This includes musical entertainment, which begins on Friday with a performance by Irish singer Rory McGettigan. On Saturday, Shades of Jade will take the stage with their dynamic blend of jazz, pop, funk and party classics. After the champions are crowned on the 18th green on Sunday, singer-guitarist The Dazzler will round off the event with an evening of his signature singalongs.
