Multiple late-Pleistocene colonisation events of the Antarctic pearlwort Colobanthus quitensis (Caryophyllaceae) reveal the recent arrival of native Antarctic vascular flora
Aim: Antarctica’s remote and extreme terrestrial environments are inhabited by only two species of native vascular plants. We assessed genetic connectivity amongst Antarctic and South American populations of one of these species, Colobanthus quitensis, to determine its origin and age in Antarctica.Location: Maritime Antarctic, sub‐Antarctic islands, South America.Taxon: Antarctic pearlwort Colobanthus quitensis (Caryophyllaceae).Methods: Four chloroplast markers and one nuclear marker were sequenced from 270 samples from a latitudinal transect spanning 21–68° S. Phylogeographic, population genetic and molecular dating analyses were used to assess the demographic history of C. quitensis and the age of the species in Antarctica.Results: Maritime Antarctic populations consisted of two different haplotype clusters, occupying the northern and southern Maritime Antarctic. Molecular dating analyses suggested C. quitensis to be a young (<1 Ma) species, with contemporary population structure derived since the late‐Pleistocene.Main conclusions: The Maritime Antarctic populations likely derived from two independent, late‐Pleistocene dispersal events. Both clusters shared haplotypes with sub‐Antarctic South Georgia, suggesting higher connectivity across the Southern Ocean than previously thought. The overall findings of multiple colonization events by a vascular plant species to Antarctica, and the recent timing of these events, are of significance with respect to future colonizations of the Antarctic Peninsula by vascular plants, particularly with predicted increases in ice‐free land in this area. This study fills a significant gap in our knowledge of the age of the contemporary Antarctic terrestrial biota. Adding to previous inferences on the other Antarctic vascular plant species (the grass Deschampsia antarctica), we suggest that both angiosperm species are likely to have arrived on a recent (late‐Pleistocene) time‐scale. While most major groups of Antarctic terrestrial biota include examples of much longer‐term Antarctic persistence, the vascular flora stands out as the first identified terrestrial group that appears to be of recent origin.
Hailing from Atlanta, Georgia, Bells and Robes will lead you on a refreshing electronic journey through time and space, combining elements of live improvisation with synth-heavy sounds of the future. Fresh off the release of their experimental debut EPs, “One Should See Sound” Part 1 and Part 2, Bells and Robes offers us a more straight-forward interpretation of their sound while maintaining their veracity as avant-garde sound creators and technicians with their new track “Duality.” Blending atmospheric chill-wave and fast-paced bass lines, Bells and Robes aims to create a vibrant energy while concurrently soothing audiophiles into a fantasy-like state of reverie.Performing over self-produced “electro-soundscapes,” Luke Sipka plays keyboard behind the boards while Dean Spaniol plays drums and creates samples. With the help of up-and-coming rapper, Swain, the trio combines the vigor and brusque electronic sound of current R&B music with the ad-libbing of a live band in a way that leaves listeners feeling calm and contented. Watch the band’s first-ever music video for “Duality” below:“We are very proud of how “Duality” was realized into our first official music video as Bells and Robes. We’ve been building with a talented team of creatives in Atlanta including Swain and his collective, LNEM, Frank Murillo, who shot the video, and all the other people involved with this project. This will be the first of many to come!” the band tells us.Bells and Robes are an Atlanta-based electronica pair taking the music world by storm. The Bells and Robes name comes from a Zen Koan titled “Bells and Robes.” This parable tells readers that “to understand intimately one should see sound.” The duo combines the high energy and crisp electronic sound of a dance DJ with the unpredictable improvisation of a jam band set. With the addition of Swain’s silver-tongued, soulful rap-style, this track is an absorbing hit for the ages. Follow the band on their website.

–all-rounder enjoying time off with family, anxious to get back to playing cricketBy Clifton RossSENIOR Guyana Jaguars all-rounder, Christopher Barnwell, says he’s cherishing this rare time off due to the COVID-19 outbreak, while maintaining his fitness with hopes of returning to action soon.The former West Indies all-rounder, who played 6 T20 internationals, chimed in on the recent break in cricket internationally, regionally and locally due to the pandemic, which has forced the world into a state of isolation.Much like his teammates, the 33-year-old is one of the few Guyanese cricketers who, when not playing for his club Demerara Cricket Club (DCC), is representing his country as one of the seniors in the 5-time Regional 4-Day title- winning Guyana Jaguars team, or playing as one of the veteran T20 guns-for-hire in the Caribbean Premier League (CPL).But with the Jaguars being forced to abandon their weekly outdoor training sessions as well as any form of playing or practice, Barnwell said it was a bit difficult to adjust to such restrictions.“It’s very difficult at the moment, not getting any outdoor training, but we all know the seriousness of the virus, so we have to take the necessary precautions to protect ourselves and our families. We have a Zoom session every morning from 9:00am to 10:00am with the trainer, so we could keep ourselves in shape”, said the hard-hitting batsman.The outbreak has cast a shroud of boredom over the country with regards to all manner of sport being placed on pause indefinitely.Nevertheless, it comes with a silver lining as athletes such as Barnwell, who’s still in the early stages of fatherhood and spends a lot of time playing and traveling as a professional sportsman, echoed the sentiments from the human side of things as he can now spend some precious time with family and loved ones.“I must say this is the longest break we’ve had within that 5 and to 6 period. I’m sure the wives, girlfriends and kids are enjoying it, so I think it (covid19) has come like a blessing in disguise”, Barnwell stated.Prior to the world entering its lockdown state, Barnwell and his team were engaged in their annual 4-Day cricket season, where they sought to defend their title for the 6th straight year.A few hiccups and the abrupt stoppage of the final two rounds of the Regional 4-Day competition resulted in the Jags falling short of their record title chase, as the Barbados Pride were crowned new champs.However, with the team well-rested and players getting ample time to heal any niggles while staying fit, Barnwell, who was on a batting surge since the Regional Super 50 tournament, was among the premier batsmen for Guyana in this year’s 4-Dayers and will be key during the upcoming season.One of the first Guyanese to ever be drafted to the Indian Premier League (IPL), back in 2013, the burly right-hander finished this 4-day season 11th overall on the leading run-scorers list with 435 runs with 2 fifties and a best of 107.Given his recent run with the bat, Barnwell admitted that he’s eager to get back into action, adding that discovering newer ways to train is key as they await the day when cricket is played again.“I’m very eager to get back on the park, playing cricket again; I just want to maintain the same focus and keep working on my game. We don’t know how long this would go for so, as professionals, we have to find a way to hit a few balls and bowl a few as well”, He ended.
Dolphins beat the Falcons 34-27 in the preseason opener at Hard Rock Stadium with 22-year old QB Josh Rosen looking good in the pocket for the Fins.Despite reportedly receiving death threats, Dolphins player Kenny Stills said again last night he doesn’t think Dolphins majority owner Stephen Ross should host a Trump reelection fundraiser today in the Hamptons. Then after the game, a Dolphin fan got down on one knee as well. But for an uplifting reason….Ryan Walton dropped to one knee and proposed to his longtime girlfriend, Amber Lynn Boutot.The two have been together for 10 years and have a four-year-old son together.Amber says she and Ryan are friends with cornerback Walter Aikens who worked with other players to make it all happen. Jason Jenkins provided the field passes and after the game Ryan popped the question.Thank God, Amber said yes. No wedding date yet, but Amber says they plan to honeymoon in some place tropical. Two people, a player and a fan got down on one knee last night at the Dolphins preseason opener for entirely different reasons.Before the game, receiver Kenny Stills knelt during the National Anthem, and he plans to do so throughout the season as he has the last three seasons.
