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!

Leaked diplomatic cables between Australia and the US Secretary of State, Hillary Clinton, have raised controversy in the Australian community. The documents were released by the whistle-blowing website Wikileaks. The cables between the then prime minister of Australia, Kevin Rudd, and the US Secretary of State, Hillary Clinton, revealed that China may need to be forced to integrate into the international community. The secret documents also contained information of a conversation between Clinton and Rudd in Washington. In the interview, Rudd stated that China was “paranoid” about Taiwan and Tibet.

The sensitive documents may place a strain on diplomatic relations between Australia and China. Despite this, Kevin Rudd reassured the public that the “robust” relationship between Australia and China wouldn’t sustain any substantial damage to the relations between the two countries. At this stage, Prime Minister Julia Gillard has provided no further comment on the matter, other than to ensure that the relationship between China and Australia would allow opinions to be expressed without any threat to either side.

At the heart of the leaks is Australian founder, Julian Assange. Wikileaks have now released 821 of their promised 251,287 US diplomatic cables. The cables are being released on a stage-by-stage basis. Earlier this week, Assange was arrested on suspicion of rape in London under a Swedish arrest warrant placed on him from a court in Stockholm on November 18.

An undercover investigation by Naperville, Illinois law enforcement has led to the arrest last Thursday of four people allegedly involved in prostitution. The stings came after police received tips that people were using websites like Craigslist and Backpage.com to sell sexual performances in Naperville hotels. 

Patricia H. Scoleri of Naperville was arrested after an unidentified neighbor observed consistently suspicious activity at Scoleri’s home. Traffic was unusually heavy and consisted mostly of luxury cars in an otherwise quiet, middle-class neighborhood. Also, the visitors were mainly middle-aged men, and an odd string of lavender-colored lights were hung on the front window.

Police say Scoleri worked alone. She was arrested at 2 p.m. local time (2000 UTC) and is charged with violation of anti-prostitution laws, anti-cannabis laws, and the Massage Licensing Act. She apparently has four children, but the Illinois Department of Children and Family Services has neither contacted her nor received a police report on her.

The second sting occurred at 5:30 p.m the same day (2330 UTC) and resulted in the arrest of Chicago resident Tonya M. Adams. She is charged with prostitution and driving without a license. Another sting about an hour later resulted in the arrests of Jessica M. Walley, a Skokie resident, and Mark A. Williams, a self-admitted Schaumburg gang member. “Walley was charged with prostitution and unlawful possession of cannabis. Williams was charged with pimping, obstructing a peace officer, driving with a suspended license and driving without insurance,” reports WBBM News Radio 780.

All four suspects are free, having paid the required ten percent of their $1,000 bail. They may face additional charges related to crack cocaine discovered during the police investigation. Arraignment is scheduled for next month at the DuPage County Circuit Courthouse in Wheaton.

Buffalo, New York —Savarino Construction Services Corp. has proposed a $7 million hotel project at the Forest and Elmwood Avenue intersection, according to The Buffalo News. The proposal calls for a 5-story, 45,000 square-foot 80-room hotel with underground parking for at least 50 vehicles, and 4,500 square-feet of retail space on the lower level.

Hans Mobius, the owner of the five properties to be purchased in the plan (1109 to 1121 Elmwood), reportedly signed a contract with Savarino to assemble the development.

“We saw a huge opportunity to bring something to the Elmwood Village that will make sense and bring a service that’s currently not available,” said Eva Hassett, vice president of Savarino. “Elmwood is such a wonderful place to eat, shop, walk and spend time. We believe this project will add to that vibrant environment.”

Some business owners in the area see it differently. Wikinews interviewed 2 of the 4 owners whose business’s would be demolished if the development goes through.

Nancy Pollina, of Don Apparel at 1119 Elmwood, who found out about the development only yesterday, said she is “utterly” against the proposal. Her apparel shop has stood at the same location for nearly 14 years. She has volunteered in the community, and helped create several gardens around bus shelters in the city, and served on Forever Elmwood Board for six years as head of Beautification. Patty Morris co-owns Don Apparel with Pollina.

“To say this is a good looking project, I want to say the emperor has no clothes. This [project] does not take into consideration the needs of the college students. I have been told by college students, these shops here, are the reason they leave the campus,” said Mrs. Pollina.

Buffalo State College is 500-feet from the intersection.

Michael Faust, the owner of Mondo Video said, “Well, I do not really want to get kicked out of here. The landlord was very open, and the deal he made with me when I moved in here was ‘the rent is cheap and I [the landlord] will not fix anything and that will not change.'” Faust said he first learned of the development plan, “about 48 hours ago. I found out on Tuesday when the Buffalo News called and asked for my opinion on this.” Faust has not said if he will make plans to relocate. “We have to see if this [house] is going to get knocked down first,” said Faust.

An “informational” meeting, where citizens can voice opinions and learn about the proposal, will be held on Tuesday February 21, 2006 at 5:00pm (eastern), at the Burchfield-Penney Art Center Gallery at Buffalo State College, Rockwell Hall.

Executive director of Forever Elmwood Corporation, Justin P. Azzarella would not comment on whether or not the organization supports the development, saying, “you will just have to come to the meeting.”

Forever Elmwood Corp. is designed to preserve and protect the unique and historic nature of Elmwood Avenue and its surrounding neighborhoods and encourage neighborhood commercial revitalization. The organization was founded in 1994.

Nearly two years ago, the Forever Elmwood Corp. assisted in the blocking of the demolition of the Edward Atwater house at 1089 Elmwood next to Pano’s Restaurant which is at 1081 Elmwood. Owner Pano Georgiadis wanted to expand his restaurant onto the property where the house now stands, but the Common Council denied his permit to demolish saying the house is a historical landmark and needs to be protected. Georgiadis, who has a bleeding ulcer, said that all the court cases landed him in the hospital. “I got a bleeding ulcer, and since then, I don’t care about this house anymore, or this city. I just go to work every day. I think [preservationists] are parasites,” said Georgiadis.

Georgiadis will not be attending Tuesday’s meeting saying, “I will be out of town.”

In 1995 Hans Mobius proposed a plan to develop a Walgreens, that was to be placed in the same location, but residents and business owners shot down the proposal. Walgreens eventually withdrew its request for a variance after pressure from the community.
