Colonies of neotropical army ants of the genus Eciton Latreille offer some of the most captivating examples of intricate interactions between species, with hundreds of associated species already described in colonies of Eciton burchellii Westwood. Among this plethora of species found with Eciton colonies, two genera of staphylinid beetles, Ecitomorpha Wasmann, and Ecitophya Wasmann, have evolved to mimic the appearance and parallel the colouration of the most abundant ant worker cast. Here, we study for the first time the association of these ant-mimicking beetles with their ant host in an evolutionary and population genetics framework. The central emphasis is on colonies of E. burchellii, the only Eciton species that harbours both genera of ant-mimicking beetles. Phylogenetic and population structure analyses using the same mtDNA COI region (802 bp) for ants and beetles indicated that speciation patterns of the myrmecophiles were congruent with specialization to a particular Eciton (sub)species. Therefore, current taxonomic treatments of Eciton and its Ecitomorpha and Ecitophya associates need revision. Molecular clock analyses suggested that diversification of the Eciton hosts pre-date that of their guests, with a possible earlier association of Ecitophya (found with a large number of Eciton species) than with Ecitomorpha (found only with E. burchellii colonies). Population-level analyses revealed that patterns of diversification for the myrmecophiles are also consistent with specialisation to a particular host across broad geographical areas but not at small geographical scales, with gene flow within each species found between host colonies, even across landscape features that are strong barriers for Eciton female-mediated gene flow.
Industry news The US Navy’s 11th Virginia-class attack submarine was christened in Groton, Conn., Nov. 2, during a late-morning ceremony at the General Dynamics Electric Boat (GDEB) shipyard.The ceremony marked the official naming of Pre-Commissioning Unit (PCU) North Dakota (SSN 784). The ship is currently under construction by both GDEB and Newport News Shipbuilding, a division of Huntington Ingalls Industries, through a teaming arrangement.Ship sponsor Katie Fowler, wife of retired Vice Adm. Jeff Fowler, was on hand to officially christen the submarine by breaking a bottle of sparkling wine against the back of the boat’s sail. “In the name of the United States, I christen thee North Dakota. May God bless her and all that sail in her,” said Mrs. Fowler just before giving the bottle a brisk swing.During keynote remarks, Commander Submarine Forces Vice Adm. Michael Connor told more than 4,500 dignitaries, Sailors, and shipyard personnel in attendance that the Navy needs the nuclear-powered attack submarine as soon as “practical.” “The Submarine Force eagerly awaits the day when USS North Dakota will assume the watch and establish a legendary reputation worthy of the name North Dakota,” said Connor. “There’s still much to be done, and there is not a moment to lose.”PCU North Dakota is the second Navy ship named after the 39th state. The first was a Delaware-class dreadnought battleship.SSN 784’s name was chosen in honor of North Dakota’s proud military heritage. Seventeen North Dakotans have been awarded the Medal of Honor for actions in combat.In future years, the attack submarine will deliver speed, agility, stealth, endurance and firepower to combatant commanders directing U.S. military operations around the globe.Virginia-class subs have improved stealth and sophisticated surveillance capabilities. Their special warfare enhancements enable them to meet multiple mission requirements.North Dakota will be able to attack targets ashore with highly accurate Tomahawk cruise missiles and conduct covert long-term surveillance of land areas, littoral waters or other sea-based forces. Its reactor plant is designed so that it will not require refueling during the planned life of the ship, reducing lifecycle costs while increasing time at sea.North Dakota’s construction will continue during the next few months as its 138 crewmembers prepare to evaluate the ship’s seaworthiness and operational performance during sea trials. “The Navy and the nation count on our submarine force to deliver relevant and powerful capabilities where and when it matters, and nothing is more important to meeting that commitment than building the most capable submarines in the world,” said Rear Adm. Ken Perry, commander, Submarine Group 2.In addition to surveillance missions, North Dakota will be able to perform anti-submarine and anti-ship warfare; deliver and support special forces; and conduct mine delivery and minefield mapping operations. “Every phase of submarine construction requires world-class expertise and close partnership, and today’s christening at Electric Boat signifies a key milestone in that partnership toward delivering North Dakota to the fleet,” Perry added.PCU North Dakota is scheduled officially join the Navy fleet once commissioned in early 2014.The submarine measures 377 feet in length and has a beam of 34 feet. It will displace 7,800 tons and be capable of operating at more than 25 knots under water.[mappress]Press Release,November 4, 2013; Image: US Navy Share this article Back to overview,Home naval-today US Navy Christens 11th Virginia-Class Attack Sub November 4, 2013 US Navy Christens 11th Virginia-Class Attack Sub

STORRS, Conn. — To prepare for the four-time defending national champions, Syracuse head coach Quentin Hillsman didn’t sleep the past two nights. He studied hours of game film and scouting reports in a quest for completing the improbable: upsetting Connecticut, winners of 108 straight games.Syracuse never had a chance. The shocks came one after the other after SU’s early 3-2 lead evaporated. In its 94-64 victory, Connecticut broke the Syracuse full-court press as if it was hardly there. All UConn’s players posed a threat from deep, which sucked the Syracuse 2-3 zone out and left open lanes for cutters. They methodically set up one another for 3-pointers on the wings and high-low passes for easy layups. Kia Nurse keyed UConn’s offensive display, scoring 29 points on 9-of-12 shooting from deep.No. 1 overall seed Connecticut (34-0, 16-0 American Athletic) hasn’t lost since November 2014. This season, despite losing its top three players to the 2016 WNBA Draft, the Huskies reloaded and went undefeated. UConn looked every part of a four-time defending national champion in handling No. 8 seed Syracuse (22-11, 11-5 Atlantic Coast) Monday night in Gampel Pavilion on UConn’s campus, ending SU’s quest for a repeat NCAA Tournament run.“We’ve just got to get better in every aspect of the game to beat a great team like that,” Hillsman said. “I’m very disappointed. The glass is empty.”In a rematch of the 2016 national championship game, which Connecticut won by 31 points, the Huskies blew out the Orange on national television. The outcome is a reminder that UConn does not lose. The Huskies’ 109-game win streak rolls on while the careers end for Syracuse’s three best players: Alexis Peterson, Brittney Sykes and Briana Day.AdvertisementThis is placeholder textWith under three minutes left and SU down 33, Peterson came off the court for the final time in a Syracuse uniform. She hugged Hillsman for nearly 30 seconds, after she scored a team-high 25 points in the final game of her college career. When the buzzer sounded, Peterson and Sykes walked off the court together, hands draped over each other’s shoulders.“We have one more chance to get something great accomplished,” Sykes said last week. The redshirt senior battled through two knee injuries to pioneer SU’s offense this season. She worked in tandem with ACC Player of the Year Peterson to form a killer one-two backcourt that averaged nearly 45 points per game. Monday, Sykes was held to five first-half points and 15 overall.Syracuse is still a budding program. For eight straight years, Hillsman’s unit has won at least 20 games. Thirty wins last year and a march all the way to the national title game put the program on the national map. Monday night, in the earliest title-game rematch in women’s Tournament history, Connecticut showed why it again will charge into the Sweet 16 with ease.“I mean, what can I say?” UConn head coach Geno Auriemma said. “Those first three quarters I just thought we were about as good as we can be.”Auriemma had no preseason All-Americans entering 2016-17. Yet Connecticut beat the other three No. 1 seeds in the Tournament by double digits in the regular season — Notre Dame, Baylor and South Carolina — and is rolling amid another undefeated season. Auriemma’s powerhouse stands at a higher level than Syracuse. No matter how well the Orange played, the Huskies answered.“It was a double whammy for Syracuse” Auriemma said. “We took away their biggest weapon (3-pointers) and we really hurt them with the 3s that we got.”Nurse’s eight first-half 3-pointers broke the UConn record of 3s in an NCAA Tournament game. In the first half, the junior guard shot better from 3 (8-of-10) than UConn did on its layups (9-for-12). She even banked in a corner 3-pointer.Moments after Nurse hit a 3-pointer, Desiree Elmore, Julia Chandler and Jade Phillips stared at her in awe as she stood near the SU bench. Twice in the second quarter, Nurse answered a Peterson deep ball with one of her own. Each time, it took her all of 12 seconds to spot up and drain the 3. She giggled her way back to defense.“When we move the ball like that,” Nurse said, “it’s hard for the defense to keep up with it. To play like that offensively and to have that cohesiveness that we had out there today, it’s a big reason a lot of our shots were as open as they were.”UConn’s outlet passes sparked a push up the court. After SU makes, UConn inbounded the ball before the Orange could match up. By the second quarter, whipping passes around the perimeter to the high post and baseline runners became rhythmic. UConn’s 94 points was the third-highest total SU’s defense allowed all season. All but three of Connecticut’s 33 made buckets were assisted on.In the second half, Syracuse found shooters early and showed some dribble penetration. Switching it up helped SU keep pace with UConn over the final 10 minutes. By then it was too late because the backbone of Syracuse’s defense faltered at the get-go.It left little doubt of what was already plenty clear: No one is better than Connecticut.
