A new paper published in the Royal Society’s Biology Letters journal, shows that early experimental studies of the peppered moth, as taught to many American high school students, are “completely correct,” co-author James Mallet, Distinguished Lecturer on Organismic and Evolutionary Biology, said.The research is particularly noteworthy, Mallet said, because it settles a decade-long controversy about whether the moths are a good example of natural selection at work.Though the moths are typically a mottled black-and-white color, scientists in England at the time of Queen Victoria began seeing increased numbers of all-black moths following the start of the Industrial Revolution. Studies later showed that the moths had benefited from the black color because they were better able to camouflage themselves against the trunks of soot-stained trees. Later research also showed that, as air quality improved, the moths’ evolution reversed course, and the number of black insects fell dramatically.Despite decades of research that showed the moths evolved in response to their environment, doubts began to surface in the late 1990s as some in the scientific community suggested that earlier studies weren’t very rigorous. Those criticisms were quickly picked up by creationists and intelligent design advocates, who used those doubts as evidence that natural selection itself was an incorrect explanation of the observed evolution.With results showing that darker moths face, on average, approximately 10 percent more predation by birds than lighter moths, the new paper — the culmination of an exhaustive, six-year experiment conducted by the late Michael Majerus, a professor of genetics at the University of Cambridge — should ultimately settle those doubts, Mallet said.“[The higher predation rate] shows a biased predation pressure against the melanic [darker] variety,” Mallet said. “The birds simply didn’t see the other moths as often because they blend in extremely well. That means natural selection is favoring the lighter-colored moths. When the trees were covered in soot, the light-colored moths were selected against. Now, on lighter trees, it’s the dark moths that are selected against.”As one of the first researchers to raise questions about earlier peppered moth studies, Majerus had meticulously designed and conducted the years-long experiment, but died before he was able to publish his findings.As one of the first researchers to raise questions about earlier peppered moth studies, Michael Majerus, a professor of genetics at the University of Cambridge, had meticulously designed and conducted the years-long experiment, but died before he was able to publish his findings.

Based on those results, Majerus then released light and dark moths in a ratio that exactly matched that found in nature, Mallet said.Beginning several hours before dawn, moths were randomly released in a series of spots — such as on tree trunks, where large branches met the trunk, or on limbs — where they typically rest during the day. Once the insects settled into position, Majerus spent two hours observing the area and recording whether the moths stayed in place or disappeared, having been eaten by birds. Based on those observations, he was able to conclude that the darker moths face a greater rate of predation against today’s clean bark.“We felt this research was incredibly important so we analyzed the data he had gathered, and wrote it up for publication,” Mallet said. “This was one of the largest experiments ever conducted on natural selection. It convincingly shows that the peppered moth is one of the best-understood examples of how natural selection can cause rapid evolution.”The paper was published Feb. 8 in the Royal Society’s Biology Letters journal.
Among those operations, the FELCN seized recently about 27 tons of ground cocaine leaves, which were disguised to look like packages of yerba mate tea. The leaves, which were found in a resident in the Department of Santa Cruz, had an estimated value of $350,000 — but they could have produced 100 kilograms of cocaine worth up to $90 million. Law enforcement officers arrested two Bolivian nationals in connection with the coca leaves, which drug traffickers allegedly intended to be shipped to Chile and then to Lebanon. Bolivia’s Special Force against Drug Trafficking (FELCN) seized 654 kilograms of cocaine hydrochloride hidden inside a vehicle that law enforcement agents stopped on April 20 at the Tambo Quemado border crossing that leads into Chile. They also arrested five Bolivian men in connection with the seizure. Bolivia allows coca leaves to be grown legally in limited amounts to make tea and medicine, and as part of Andean religious rites. However, the only major purpose for shredded coca leaves is to prepare them to be manufactured into cocaine. The Colombian National Navy’s Poseidón Task Force Against Drug Trafficking found and destroyed two cocaine laboratories in the Department of Nariño on April 20. Troops seized 1,000 kilograms of coca leaves, 1,460 kilograms of solid chemicals and 1,153 gallons of liquid chemicals used in the cocaine-making process, 1,060 gallons of gasoline, and other supplies from the two structures. Colombian Marines destroyed all of the contraband in a controlled manner.

Daigneault, CCDA new idea has been popping up lately among credit unions: the development of junior boards. No, I’m not talking about associate board member programs, whereby potential directors are groomed and trained for a year or two before becoming full-fledged members of your credit union’s governing board. Junior boards are a whole different animal.For example, consider the junior board of $827 million U.S. Eagle Federal Credit Union, Albuquerque, N.M., Its junior board is composed of eight teens – all upper-class high school students or college freshmen. In a recent Albuquerque Business First article, Director Pamelya Herndon, CPA, says it was “an idea to get more young women involved…What we try to teach is financial literacy, and to get other board members to come in and talk about what they do.”Here are some possible benefits of junior boards, both for the credit union and the junior board members:Junior board members can serve as a bridge (ambassadors) between the credit union and the late teen-early 20s age market. continue reading »

But Van Gaal does not think that was a sign from De Gea that his four-year spell at United was up. ”I believe still that David de Gea shall stay,” the United manager said. Following the stalemate against Arsenal, Van Gaal sounded somewhat more pessimistic about his star goalkeeper, who was named club player of the season this week for the second successive year. Two days after saying he had drawn up a list of potential replacements for United’s player of the season, the Dutchman admitted the lure of returning to his homeland may end up being too strong for De Gea. Van Gaal said in his post-match press conference last weekend: ”He is Spanish and his girlfriend is Spanish, now a Spanish club is coming, his father and mother come every week or every two weeks here, so it is difficult. But we would be very happy if he stays.” But there was a more optimistic tone from Van Gaal when he spoke at his weekly press conference at Carrington on Friday. The Spain international may even take the gloves back off Victor Valdes, who replaced De Gea after he suffered his hamstring injury. ”I want to play him against Hull City because of the fact that I have to put out my strongest team,” Van Gaal said. Real Madrid are interested in signing De Gea this summer and contract talks between United and the Spaniard have so far been unproductive. The 24-year-old waved to United fans as he left the pitch at Old Trafford last week after suffering an injury in the 1-1 draw against Arsenal. Press Association Louis van Gaal gave hope to Manchester United fans on Friday when he said he was optimistic about the chances of goalkeeper David de Gea staying at Old Trafford. ”And I think with David de Gea we have the strongest team. “I think De Gea is a better goalkeeper (than Valdes). ”He (De Gea) has trained today for the first time. He still had a problem so we have to wait and see tomorrow.” It is not just De Gea’s future that has been the source of speculation over the last few weeks. A number of players still have question marks over their futures. Robin van Persie, Anders Lindegaard, Rafael, Jonny Evans, Nani, Adnan Januzaj, James Wilson, Radamel Falcao and Javier Hernandez all could be playing their football elsewhere next year – either on loan or permanently. Van Gaal has spoken to a number of them about their futures already and will conclude discussions over the weekend. ”I shall talk with them maybe tomorrow,” Van Gaal said. ”We have a farewell drink after the match. I have the Monday to talk, and I have already this week for some players to talk so I shall do that. ”You have to wait and see how these talks develop in staying or going away.” After those discussions end, Van Gaal will fly to his villa in the Algarve for a well-earned rest. The 63-year-old had just two days off after the World Cup so he is looking forward to a break, but his phone will be close by his side just in case he is needed for any transfer business. “Immediately after the match we will have a farewell drink and after that we have a recovery day, and then we go off,” he told MUTV. “All the players have to fly out to international duties but I will go on holidays and I’m willing to go to my paradise in Portugal.” Asked if all transfer business will be left to executive vice-chairman Ed Woodward during that time, Van Gaal said: “No, not to Ed because you also have a telephone and computer, so we are always in contact. “As a manager, you never have holidays but I am in a better climate than here in Manchester. I am sorry to say that!” Van Gaal, who has Wayne Rooney available for Sunday’s match, wants to end the season on a high even though he knows victory against Hull would mean relegation for former United defender Steve Bruce. Van Gaal added: ”I have said to the players in spite of him being a Manchester United guy, we have to do what everybody is expecting from us. ”We have the same approach as ever. We have to give our utmost best.”
If you live work or play in Broward County, officials have some news for you.The county’s nighttime curfew has been extended, they announced Wednesday.However, residents will no longer be legally responsible for making sure their guests wear masks.The changes came in an order signed by County Administrator Bertha Henry.It extends the county’s curfew, which runs from 11 p.m. to 5 a.m. daily, through at least this Monday.The curfew, which was imposed two weeks ago, was originally set to expire on Saturday.Broward Mayor Dale Holness said it could be extended further, although there is no consensus on how long to extend it.The curfew is “something we believe has worked for us in reducing the number of parties that were happening overnight,” Holness said. “As a result of actions that we’ve taken, we’ve seen some leveling off of the spread of the virus.”In addition, Broward’s mask mandate remains in effect, albeit with a slight change.The new order clarifies that residents are not required to wear the coverings inside their homes, nor are they responsible for making their guests wear masks.State rules still prevent gatherings of more than 10 people if they are not from the same family, but guests are now responsible for wearing masks if social distancing is not possible.The policy change came days after a Broward County resident sued the county over the provision that made people responsible for their guests’ behavior.#Broward Mayor @HolnessD9 announces new County Administrator Emergency Order 20-23 https://t.co/tFn80a5dnR— Broward County Commission (@browardinfo) July 29, 2020 That lawsuit claimed that the requirement violated constitutional protections against unreasonable searches and seizures by the government.Violators of the mandate were subject to civil and criminal penalties, including a $1,000 fine for each violation.In another change announced Wednesday, rules for safety signs in English, Creole and Spanish also will now apply to all businesses, rather than just to restaurants and retail shops.On a related note, a recent crackdown by the Broward Sheriff’s Office on parties and “roving car clubs” is helping to curb violence and the local spread of the virus, according to Sheriff Gregory Tony.“Two weeks ago, we launched an enforcement operation which was twofold,” he said. “One, reducing the large parties that were occurring where we had got to the point where 1,100-plus calls for service had come in through the Sheriff’s Office related to these parties.”The efforts also targeted what Tony referred to as “roving car clubs,” where groups of people would drive 20 and 40 cars through the county and congregate for parties. Some of those events would end in violence, he adds.Deputies responded to and broke up 13 gatherings; issued 260 citations; arrested 25 people on charges such as grand theft and driving under the influence; and seized three guns. Sheriff Tony said all of the incidents were resolved without violence.He added that the enforcement operations will continue for the time being.The Florida Department of Health reported Wednesday that Broward has 52,970 confirmed cases of COVID-19, and 638 deaths.
Without a doubt, UW’s brightest star is tailback John Clay. He’s also one of their biggest. At over 250 pounds, the junior regularly plows through defenders, but maintains the breakaway ability to take it the distance on any given play. Clay earned Big Ten Offensive Player of the Year honors last season after compiling 1,517 yards and 18 touchdowns, and the spotlight will once again be focused on the bruising back. With all five starters on the offensive line returning and a wealth of experience under his belt, Clay should produce another tremendous season on the ground for the run-happy Badgers and perhaps earn an invite to the Heisman Trophy presentation at season’s end.Scott Tolzien – Sr., quarterback, No. 16 With some newcomers debuting on the defensive line, UW is lucky to have J.J. Watt ready to lead the way. The overpowering defensive end is hard to miss – listed at 6-foot-6 and 285-pounds. However, the junior has quickness off the ball and brute strength, and he will be counted on to be a disruptive force on the line of scrimmage for the Badger defense after recording 15.5 tackles for loss in 2009. After that breakthrough season, look for Watt to wreak havoc in opponent’s backfields and make big plays week in and week out this fall.Chris Borland – Soph., linebacker, No. 44 When the UW offensive coordinator Paul Chryst needs a big play through the air, he’ll look no further than No.1. Nick Toon has all the physical tools to be a dominant wideout – soft hands, a 6-foot 3 frame, terrific speed and the leaping ability to make jaw-dropping catches. Toon reeled in 54 catches for over 800 yards last season and the junior appears ready to burst onto the scene as one of the conference’s top receivers this fall.J.J. Watt – Jr., defensive end, No. 99 Running backs tend to get the headlines here in Madison, but a potent aerial attack should be in full force with returning starter Scott Tolzien under center. Tolzien was the surprise winner of the starting job last fall, but after breaking the UW record for completions in a season and leading the team to 10 wins, no one doubts Wisconsin’s signal caller. Tolzien shows toughness and grit, taking hits to complete clutch throws, but he struggled in big games, throwing costly picks against Ohio State and Iowa. It’s been years since UW had an established returning starter at the quarterback position and if Tolzien can cut down on the interceptions, he could produce one of the best seasons for a Badger QB in recent memory.Lance Kendricks – Sr., tight end, No. 84 Have you ever seen someone get hit so hard that the decal on the side of their helmet flew off? Badger fans have seen it with their own eyes thanks to the one and only Jay Valai. Standing at 5-foot-9 Valai is known as one of the Big Ten’s hardest hitters and opponents are always well aware of his presence on the field. The energetic, smack-talking Valai brings a lot of personality and physicality to the UW secondary. And he’ll be the first to tell you. You never know what kind of production you’re going to get from a true freshman, but it didn’t take long for the UW coaches to realize they had something special in Chris Borland. After posting 54 tackles, 5 sacks, and forcing and recovering three fumbles, Borland was named the Big Ten’s Freshman of the Year. The multi-talented Borland was a sparkplug on defense, but he also returned six kickoffs and even hit three extra points when UW had some kicking issues in its game against Hawaii. Not bad for a freshman.Jay Valai – Sr., safety, No. 2 Any program that has Big Ten title aspirations needs star power. And entering the 2010-2011 season, it’s safe to say Bret Bielema and the Wisconsin Badgers have plenty of it.UW has tremendous depth and experience returning this fall, but there is a select group of Badgers that will be counted on to deliver in big ways.Here is a rundown of the seven Badgers you must know before entering the gates of Camp Randall Stadium.John Clay – Jr., running back, No. 32 The Badgers churn out NFL-caliber tight ends on a regular basis, and Lance Kendricks is next in line. A converted wide receiver, Kendricks has tremendous athleticism and reliable hands that make him a nightmare for opposing defenses. And after years in the UW program, the senior has developed into a physical blocker. Having recorded over 100 yards receiving in last season’s Champs Sports Bowl victory over Miami, Kendricks is primed for a big season as UW’s go-to target on third downs and in the red zone.Nick Toon, Jr., wide receiver, No.1
