Resolving the northern hemisphere source region for the long-distance dispersal event that gave rise to the South American endemic dung moss Tetraplodon fuegianus

first_imgPREMISE OF THE STUDY: American bipolar plant distributions characterize taxa at various taxonomic ranks but are most common in the bryophytes at infraspecific and infrageneric levels. A previous study on the bipolar disjunction in the dung moss genus Tetraplodon found that direct long-distance dispersal from North to South in the Miocene–Pleistocene accounted for the origin of the Southern American endemic Tetraplodon fuegianus, congruent with other molecular studies on bipolar bryophytes. The previous study, however, remained inconclusive regarding a specific northern hemisphere source region for the transequatorial dispersal event that gave rise to T. fuegianus. METHODS: To estimate spatial genetic structure and phylogeographic relationships within the bipolar lineage of Tetraplodon, which includes T. fuegianus, we analyzed thousands of restriction-site-associated DNA (RADseq) loci and single nucleotide polymorphisms using Bayesian individual assignment and maximum likelihood and coalescent model based phylogenetic approaches. KEY RESULTS: Northwestern North America is the most likely source of the recent ancestor to T. fuegianus. CONCLUSIONS: Tetraplodon fuegianus, which marks the southernmost populations in the bipolar lineage of Tetraplodon, arose following a single long-distance dispersal event involving a T. mnioides lineage that is now rare in the northern hemisphere and potentially restricted to the Pacific Northwest of North America. Furthermore, gene flow between sympatric lineages of Tetraplodon mnioides in the northern hemisphere is limited, possibly due to high rates of selfing or reproductive isolation.last_img read more

Toaster tags

first_imgToaster graffiti has been, ahem, popping up more of late. Sightings date back to 2002, from New York to Birmingham, and this recent daub was spotted in London. It could be a reference to an early Jamaican precursor to rap music, known as ‘toasting’, or it could be about elevating an everyday device to cult status. As long as it gets people eating more toast, we’re not complaininglast_img

Two named Abramson winners

first_imgSelim Berker, an assistant professor of philosophy, and Joshua Greene, the John and Ruth Hazel Associate Professor of the Social Sciences, are this year’s winners of the Roslyn Abramson Award, given annually to assistant or associate professors for excellence in undergraduate teaching.The $10,000 award, established with a gift from Edward Abramson ’57 in honor of his mother, goes each year to members of the Faculty of Arts and Sciences (FAS) “in recognition of his or her excellence and sensitivity in teaching undergraduates.” Recipients are chosen on the basis of their accessibility, their dedication to teaching, and their ability to communicate with and inspire undergraduates.“The Faculty of Arts and Sciences is deeply committed to strengthening research, teaching, and learning, and both Joshua Greene and Selim Berker exemplify that commitment,” said FAS Dean Michael D. Smith, the John H. Finley Jr. Professor of Engineering and Applied Sciences. “These professors make strong connections with their students. They foster excitement in research and exploration that goes beyond the classroom walls. On behalf of the College and the entire FAS, I offer my thanks and congratulations.”Joshua GreeneGreene ’97, said he was honored when he found out that he was a recipient of this year’s Abramson Award.“Teaching is something that I really love,” said Greene. “As a researcher, you focus on the frontiers and the edges, but the undergrads that you teach are coming into this all new. I try to first determine what’s really important and what’s really interesting and try to show them the whole field, not just one narrow area where a researcher may focus.”Greene’s research centers on moral judgment and decision-making, but his teaching style is focused on engaging his students. Even in a lecture, Greene said he makes it a point to take a more conversational approach, which is well-suited to the subject matter of social psychology.“The experiments are really stories because you can present the research through the eyes of people who are being studied. If you start with these concrete instances, you can build to broader principles and connect them to real life so you’re not just playing a theory game,” Greene said. “There is something to be said for a good lecture, but I do think interactive learning is very important.”Seeing as many of the undergraduates he teaches will not follow a career path into psychology, Greene said he tries to get his students to focus on asking the right questions to solve a problem.“I don’t want them to just listen to lectures, read books, and answer questions because I know they will eventually forget most of the facts they needed to know to answer questions. What I really want is for them to be able to apply what they have learned,” Greene said. “Here at Harvard we have so many people who will be running the world in 10 years or 20 years, maybe even five years, and if they do not remember anything else from my class I hope they take away a mindset and a view of the world. We would all be better off if we stopped and asked questions, and by approaching a problem with the right method you can figure out things you never thought you could figure out.”“I often wish I had more time for my own research, but I’m also unwilling to take time away from my students,” said Selim Berker, who was named an Abramson winner. The award is given to two professors “in recognition of his or her excellence and sensitivity in teaching undergraduates.” Photo by Rose Lincoln/Harvard Staff PhotographerSelim BerkerFor Berker ’98, A.M. ’00, discussions with students are what drive much of his classroom time.“Even in my lecture classes I leave about half the time for discussion,” he said. “I also make a point of learning every student’s name by the second week of classes in order to foster a relaxed atmosphere in which conversation flows easily. Students are most engaged and interested when they are really grappling with the issues.”Another way Berker engages his students is by commenting heavily on their papers and having them rewrite them.“Most students show up to college not having much — or any — experience writing a philosophy paper, which isn’t like writing an English or history paper. It takes time to learn how to present a philosophical argument effectively. So in every course I teach I have my students rewrite at least one paper in light of my comments,” Berker said. “Most students seem to really appreciate the opportunity and put a lot of effort into rewriting their papers.”Like most scholars, Berker is dedicated to his research, which includes ethics and epistemology. Time for research can be limited when poring over student papers, holding office hours, and even meeting with students who are no longer in his class.  But Berker said teaching is an important part of his job and one he takes very seriously.“I often wish I had more time for my own research, but I’m also unwilling to take time away from my students,” he said. “It is important to me to teach students how to read a text carefully, present a strong argument, and write well. It is important they develop these skills. And on the best days, they help me see a new approach to a problem or inspire me after a two-hour conversation about philosophy.”last_img read more

Orsted, Yara International link up in green ammonia development effort

first_imgOrsted, Yara International link up in green ammonia development effort FacebookTwitterLinkedInEmailPrint分享Bloomberg:Orsted A/S, the world’s biggest developer of offshore wind farms, plans to use its latest Dutch installation to make green ammonia for use in fertilizer.The Danish utility will work with the fertilizer giant Yara International ASA to use wind power to create hydrogen and turn it into ammonia. The project could produce about 75,000 tons of green ammonia a year, cutting Yara’s carbon footprint.Green ammonia is seen as an option to store hydrogen or use it for industrial applications and transportation. Chemical fertilizers use ammonia, made up of nitrogen and hydrogen. The most common and cheapest way of making hydrogen today emits carbon dioxide.The proposed plant in the Netherlands would use 100 megawatts of electrolyzers — machines powered by electricity that separate the hydrogen atoms in water from the oxygen. Orsted is currently building a 752-megawatt wind farm off the Dutch coast that could provide the facility with green power.The green ammonia produced at the plant would be a small fraction of Yara’s demand, about 3% to 4% of the ammonia used at its factory in Sluiskil in the western Netherlands. But the scale would still make it one of the biggest green hydrogen facilities in the world.“Green ammonia today doesn’t exist. It’s a market that will need to be created,” Sammy Van Den Broeck, Yara’s vice president for climate neutrality, said in an interview. “This is a first step into the trajectory of climate neutrality.”[Will Mathis]More: Green ammonia for fertilizer planned by giant wind farm builderlast_img read more

Trail Mix: Circus No. 9 Live at The Down Home!

first_imgKids these days.Circus No. 9, a progressive string band with roots in Southwest Virginia and Northeast Tennessee, is long on talent and short on legal drinkers. With a couple members of the band still in their teens, and most no older than mid-twenties, this collection of youthful pickers proves quickly that age is no prerequisite for a smokin’ bluegrass band.I was drawn to the band by my interest in Thomas Cassell, an award winning mandolinist that I profiled here on the blog back in August. Cassell, after having played the mandolin for just a couple years, had the audacity – and talent – to go out and win the mandolin contest at Rockygrass this summer. Cassell is joined in Circus No. 9 by Matthew Davis, winner of the Walnut Valley national banjo championship, Colin Hotz on vocals/guitar, Michael Testagrossa on dobro, and Angel Edgemon on upright bass.Circus No. 9 has been off to a hot start. Most of December has seen them on the road, with gigs across the Southeast. This weekend, the band will be at The Down Home in Johnson City, one of the most acclaimed venues in Northeast Tennessee.I recently caught up with Thomas to chat about the new EP, starting a band, and even a little bit about the circus.BRO – When we last chatted, you had just wrapped up high school and were getting ready to start college. How are things going with balancing school and being in a touring band?TC – Balancing school and touring has been a battle, but I think that I’m close to have it figured out. It’s tough having multiple commitments like that, but nothing is more satisfying than playing a show in a different city every night.BRO – You guys came out of the gate pretty hard, with a bunch of dates and a new EP. What have you found to be the hardest part about putting together a new band?TC – Getting Circus No. 9 going so quickly wasn’t easy. Time wasn’t on our side, which accounted for some errors and cut corners here and there. Luckily, we were able to pick up around 25 dates. We’ve been touring for a month now and things are coming together nicely.BRO – We are featuring “Down The Road,” an old Flatt & Scruggs tune, on this month’s Trail Mix. How hard is it to balance the itch to reinterpret the song while remaining true to the spirit of the original?TC – I have this strange belief that the best way to preserve “traditional” bluegrass is to change it and try to make it new. People will then be able to see and appreciate the music’s roots and where your drew the influence from. It’s fun to play the original versions, but when a song has been recorded by hundreds of bands, we want to have our own version.BRO – You guys are playing The Down Home, a tremendous acoustic venue, this weekend. What are some of the more memorable shows you have caught there?TC – I’ve seen some great shows at The Down Home. Russell Moore, Chris Eldridge and Julian Lage, John Cowan, Joe Walsh, and Billy Strings, but nothing compares to Newfound Road’s Live At The Down Home record. I wasn’t actually there, but that was the record that inspired me the most to pick up the mandolin.BRO – Human cannonball or trapeze artist. If you had to do just one . . . . TC – Human cannonball. No doubt. I guess the trapeze thing is cool, but I mean . . . being a human cannonball? I might have to work that into my soloing.Circus No. 9 will hit the stage at The Down Home in Johnson City this Saturday at 8:00. Trail Mix would like to give you a chance to take in the show for free! Two spots on the guest list await one person who correctly answers the trivia question below. Take a shot at it and send your answers to [email protected] A winner will be chosen from all of the correct responses received by noon on Friday, January 20th.Good luck!!!Question . . . . The mandolin that Thomas Cassell won at Rockygrass last year bears the signature of what legendary mandolinist?And for more information on Circus No. 9, tour dates, and how you can get the new EP,  be sure to check out the band’s website.
