In May, periodical cicadas with 17 years life cycle emerged on the East Coast of the USA after underground development as juveniles since 1996. Researchers and scientists worked to map and study the rare wave, and the locals prepared for the noisy event. First recorded in 1666, the Magicicada septendecim species recently emerged in 1979, 1996, this year, with a next wave due in 2030.

This week, Wikinews interviewed Chris Simon, an ecology and evolutionary biologist at University of Connecticut, about the cicadas.

((Wikinews)) What caused your initial interest in periodical cicadas?

Chris Simon: As an undergraduate student, I was interested in the formation of species so when I went to graduate school I looked for a study organism that was likely to be in the process of forming new species. I chose periodical cicadas because they are broken up into reproductively isolated broods (or year classes). Reproductive isolation leads to speciation so I planned to study biochemical differences among the broods.

((WN)) You study the emergence of the periodical cicadas. What do you study? What observations are you making?

CS: We record exactly where each cicada population emerges (using GPS automated mapping and crowd sourcing). We record the presence or absence of each of the three morphologically distinct species groups of periodical cicadas (Decim group, Cassini group, and Decula group). We collect specimens for DNA analysis. We look for cicadas coming up one and four years early and late. We dig up cicada nymphs and monitor their growth rates.

((WN)) What equipment do you use?

CS: Nets, shovels, automated GPS recorders, cameras, laptop computers, automated DNA sequencers.

((WN)) Do you study the periodical cicadas with anyone else? What is their role?

CS: Yes, there are a large number of people studying periodical cicadas in my lab and in other labs. My lab is made up of Research Scientists, Postdoctoral Researchers, a technician, graduate students, and undergraduates. Research Scientist John Cooley is the leader of the GPS mapping project; he invented the automated GPS recorder; he built our crowd-sourcing website, and he is instrumental in public outreach. Postdoctoral research David Marshall also participates in the mapping project and leads the part of the research related to the mapping of stragglers. John and Dave and Technician Kathy Hill all study periodical cicada mating behavior and conduct mating and hybridization experiments. One of my graduate students Beth Wade has participated in the nymph collections and will soon start genetic work involving genome wide association mapping designed to locate genes related to life cycle. My graduate student Russ Meister is studying the genes of the bacterial endosymbionts of cicadas. My current undergraduate honors student Erin Dwyer is also studying the development of Magicicada nymphs and is helping to design a lab exercise for college students around the eastern US to do the same. Many of my past undergraduate students have studied the biochemical genetics and development of periodical cicadas. See the Simon Lab website.

CS: We are collaborating with Teiji Sota at the University Kyoto and Jin Yoshimura at Shizuoka University in Japan. They are studying the phylogeography of Magicicada. We are collaborating with John McCutcheon of the University of Montana who is studying the endosymbiont genomes.

CS: We are also collaborating with ecologists Rick Karban and Louie Yang, both professors at UC Davis who have an interest in cicada population dynamics and nutrient cycling in the ecosystem.

((WN)) You studied the periodical cicadas in 1979 and 1996 too. What changes with time?

CS: I have studied periodical cicadas since I was a student back in 1974. What changes with time is increased human development constantly shrinking the patch size of cicada populations.

((WN)) What are your thoughts on the long life span of the periodical cicadas? Why could it be so? What advantages and what disadvantages does it have?

CS: Most or all cicadas have long life cycles compared to your typical annual insect. Examples have been found of two-year to 9-year cycles in different species. Periodical cicadas evolved an even-longer life cycle and I think that part of this relates to the evolution of their synchronized life cycles and peculiar safety-in-numbers strategy for survival. To become synchronized, periodical cicadas had to evolve an exact length life cycle and all adults would have to appear in the same year. Because the nymphs grow at different rates underground, a longer life cycle and a way of counting years must have evolved so that the individuals that get to the last nymphal (underground juvenile) stage first would wait long enough for all other individuals in the population to become ready to emerge.

((WN)) News reports mention this is ‘Brood II’ of the periodical cicadas. What are the distinctive features of this specific species and what is its full scientific name?

CS: The same species exist in multiple broods. No species is restricted to Brood II. The three species present in Brood II are: Magicicada septendecim, M. cassini, and M. septendecula. These same three species are found in every 17-year brood (except the farthest north which only has M. septendecim).

((WN)) At what depth do the cicadas juveniles live underground?

CS: Most live within the top foot of soil but some have been found deeper. We do not know if they go deeper in winter. We need to do much more digging to understand the nymphs.

((WN)) How do people prepare for the cicada emergence?

CS: Of course various people prepare in different ways. Ideally, everyone prepares by studying information available on the web (especially on our websites Magicicada Central and Magicicada.org).

((WN)) Do cicadas affect transport in the local area?

CS: No, not really. Occasionally individuals can be seeing flying across highways and sometimes they smash into cars.

((WN)) Do cicadas usually stay outside or do they also invade houses too?

CS: They stay outside. One might accidentally fly in through an open window but that would be rare.

((WN)) What do the cicadas eat?

CS: Cicadas suck xylem fluid (the watery fluid coming up from the roots of plants) in deciduous forest trees and herbs. Essential amino acids in the cicada diet are supplied by their bacterial endosymbionts. There are two species of endosymbionts. One makes 8 essential amino acids and one makes two essential amino acids.

((WN)) Do cicadas damage crops or city vegetation? What damage?

CS: Cicadas do not chew leave so they do not damage crops like other insects. They can inflict some damage by their egg laying. Cicadas lay eggs in pencil-sized tree branches. If there are not enough branches available, too many female cicadas may lay eggs in a single branch weakening it and making it susceptible to breakage by wind. This can sometimes cause damage in fruit orchards. If the branches break, the eggs die so this behavior is selected against by natural selection.

((WN)) Thank you.

CS: You’re welcome. I am happy to have this opportunity to communicate with your readers!

Copenhagen, Denmark – The Danish Integration Minister Rikke Hvilshøj’s car was set ablaze outside her family-home on the morning of Wednesday 8 June. From there, the fire spread to the family’s garage, and further on to the side of the house, damaging the roof above the kitchen and children’s room.

At the same time, an e-mail was sent to several media agencies, where a group calling themselves “Action Group Beate” claimed responsibility, saying it is a “protest against the racist immigrational laws of Denmark”. The police found the computer used for sending the mail within a few hours, and closed down the cybercafé whilst removing the computer.

Throughout the Danish political system politicians from both the ruling party and the opposition have expressed their outrage over the terrorism.

The insurance company is currently assessing the amount of damage done to the home, but so far they have made an estimate of £27.000, just for the house damages.

Dozens of students and teachers were stung by yellow jacket wasps Monday at a middle school in Cranston. The attack occurred around 10:45 a.m., according to Ray Votto, the chief operating officer for Cranston Public Schools.

It is suspected that during a routine fire drill, students exiting the building disturbed the wasps’ nest in a field behind the school. Votto said, “When kids exited towards the back of the school building near our portable classrooms, they walked into a field and may have disrupted a nest”.

The Cranston Fire Department and school nurses responded to the scene to provide medical assistance. A total of 25 students, one of whom was hospitalized, and four teachers were stung, some multiple times. All of the students and one teacher were sent home.

Wednesday, March 30, 2005A survey carried out by BBC Wales has revealed that the contents of a school meal in Wales cost on average just £0.49 per pupil. Average spending on meal ingredients varied slightly from council to council; with the Cardiff City council spending just £0.40 on each meal, whilst Powys council lavished £0.69 per pupil.

The survey follows a recent surge in media coverage of the eating habits of teenagers and children in the UK. Celebrity chef Jamie Oliver recently embarked on a campaign to improve food standards and raise awareness in schools. In response to his campaign the government has promised to spend an additional £280 million over three years on school food in England.

The survey covered twenty councils throughout Wales.

Police in the West Midlands in England today said nearly 200 kilograms worth of drugs with value possibly as great as £30 million (about US$49 million or €36 million) has been seized from a unit in the town of Brownhills. In what an officer described as “one of the largest [seizures] in the force’s 39 year history”, West Midlands Police reported recovering six big cellophane-wrapped cardboard boxes containing cannabis, cocaine, and MDMA (“ecstasy”) in a police raid operation on the Maybrook Industrial Estate in the town on Wednesday.

The seized boxes, which had been loaded onto five freight pallets, contained 120 one-kilogram bags of cannabis, 50 one-kilogram bags of MDMA, and five one-kilogram bricks of cocaine. In a press release, West Midlands Police described what happened after officers found the drugs as they were being unloaded in the operation. “When officers opened the boxes they discovered a deep layer of protective foam chips beneath which the drugs were carefully layered”, the force said. “All the drugs were wrapped in thick plastic bags taped closed with the cannabis vacuum packed to prevent its distinctive pungent aroma from drawing unwanted attention.” Police moved the drugs via forklift truck to a flatbed lorry to remove them.

Detective Sergeant Carl Russell of West Midlands Police’s Force CID said the seizure was the largest he had ever made in the 24 years he has been in West Midlands Police and one of the biggest seizures the force has made since its formation in 1974. “The impact this seizure will have on drug dealing in the region and the UK as a whole cannot be underestimated”, he said. “The drugs had almost certainly been packed to order ready for shipping within Britain but possibly even further afield. Our operation will have a national effect and we are working closely with a range of law enforcement agencies to identify those involved in this crime at whatever level.”

Expert testing on the drugs is ongoing. Estimates described as “conservative” suggest the value of the drugs amounts to £10 million (about US$16.4 million or €12 million), although they could be worth as much as £30 million, subject to purity tests, police said.

Police arrested three men at the unit on suspicion of supplying a controlled drug. The men, a 50-year-old from Brownhills, a 51-year-old from the Norton area of Stoke-on-Trent in Staffordshire, and one aged 53 from Brownhills, have been released on bail as police investigations to “hunt those responsible” continue. West Midlands Police told Wikinews no person has yet been charged in connection with the seizure. Supplying a controlled drug is an imprisonable offence in England, although length of jail sentences vary according to the class and quantity of drugs and the significance of offenders’ roles in committing the crime.

Sweden’s first royal wedding since 1976 took place Saturday when Crown Princess Victoria, 32, married her long-time boyfriend and former personal trainer, Daniel Westling, 36. The ceremony took place at Stockholm Cathedral.

Over 1,200 guests, including many rulers, politicians, royals and other dignitaries from across the world, attended the wedding, which cost an estimated 20 million Swedish kronor. Victoria wore a wedding dress with five-metre long train designed by Pär Engsheden. She wore the same crown that her mother, Queen Silvia, wore on her wedding day 34 years previously, also on June 19. Victoria’s father, King Carl XVI Gustaf, walked Victoria down the aisle, which was deemed untraditional by many. In Sweden, the bride and groom usually walk down the aisle together, emphasising the country’s views on equality. Victoria met with Daniel half-way to the altar, where they exchanged brief kisses, and, to the sounds of the wedding march, made their way to the the silver altar. She was followed by ten bridesmaids. The couple both had tears in their eyes as they said their vows, and apart from fumbling when they exchanged rings, the ceremony went smoothly.

Following the ceremony, the couple headed a fast-paced procession through central Stockholm on a horse-drawn carriage, flanked by police and security. Up to 500,000 people are thought to have lined the streets. They then boarded the Vasaorden, the same royal barge Victoria’s parents used in their wedding, and traveled through Stockholm’s waters, accompanied by flyover of 18 fighter jets near the end of the procession. A wedding banquet followed in the in the Hall of State of the Royal Palace.

Controversy has surrounded the engagement and wedding between the Crown Princess and Westling, a “commoner”. Victoria met Westling as she was recovering from bulemia in 2002. He owned a chain of gymnasiums and was brought in to help bring Victoria back to full health. Westling was raised in a middle-class family in Ockelbo, in central Sweden. His father managed a social services centre, and his mother worked in a post office. When the relationship was made public, Westling was mocked as an outsider and the king was reportedly horrified at the thought of his daughter marrying a “commoner”, even though he did so when he married Silvia. Last year, Westling underwent transplant surgery for a congenital kidney disorder. The Swedish public have been assured that he will be able to have children and that his illness will not be passed on to his offspring.

Westling underwent years of training to prepare for his new role in the royal family, including lessons in etiquette, elocution, and multi-lingual small talk; and a makeover that saw his hair being cropped short, and his plain-looking glasses and clothes being replaced by designer-wear.

Upon marrying the Crown Princess, Westling took his wife’s ducal title and is granted the style “His Royal Highness”. He is now known as HRH Prince Daniel, Duke of Västergötland. He also has his own coat-of-arms and monogram. When Victoria assumes the throne and becomes Queen, Daniel will not become King, but assume a supportive role, similar to that of Prince Phillip, the husband of the United Kingdom’s Queen Elizabeth II.
