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!

New Orleans, Louisiana — After Category 4 storm Hurricane Katrina slammed into New Orleans, on the night before August 29, 2005, several flood control constructions failed. Much of the city flooded through the openings. One of these was the flood wall forming one side of the 17th Street Canal, near Lake Pontchartrain. The U.S. Army Corps of Engineers (USACE) is the primary agency for engineering support during such emergencies. A USACE team was assessing the situation in New Orleans on the 29th, water flow was stopped September 2nd, and the breach was closed on September 5th.

In the United States, there are two major political parties; the Republican and the Democratic. However, there are several other minor – commonly referred to as “third” – parties. One of these is the Modern Whig Party, which has been steadily increasing in popularity over recent months.

Last week, Wikinews reporter Joseph Ford was able to speak with MWP Chairman Mike Lebowitz about how his party was formed, what it stands for, and why you should consider joining. The interview can be read below.

Interstate 80 is closed in Cedar County, Iowa, east of the Iowa City area, due to flooding from the Iowa River and Coralville Lake. The flooding that has devastated cities in eastern Iowa has travelled downstream and is now threatening Iowa City and Coralville, both of which have issued evacuations for low-lying areas. Flooding on the Cedar River earlier filled Waterloo, Cedar Falls, and Cedar Rapids, Iowa, with record-breaking water levels.

Interstate 80 is closed between mile markers 266 and 267, with a 281-mile long detour to get around it: Eastbound through traffic must leave I-80 at Des Moines and travel north along Interstate 35 then east to Dubuque via U.S. Route 20, where it can move south along U.S. Route 61 to return to Interstate 80 at the Quad Cities, with westbound through traffic following the opposite route. Local traffic is being allowed, since this shuts off a 150-mile stretch of highway.

Interstate 380 has also been closed, between mile markers 4 and 10, due to flooding from the Iowa River and Lake Coralville. This, combined with the flooding of the bridges across the Cedar River at Cedar Rapids, effectively cuts Cedar Rapids off from Iowa City; the only way between the two cities, normally 30 miles apart, is a 281-mile long detour that takes drivers through Des Moines.

The Cedar River at Cedar Rapids crested today at a record-breaking 31.1 feet, nearly 20 feet above flood stage. The Iowa River is expected to crest at Iowa City at 33 feet, 11 feet over flood stage and 4.5 feet over the record, on the morning of June 17.

The Spanish word “tortuga” means “turtle.” But in the wake of the New Orleans disaster, the USS Tortuga is helping other animals.

For nearly two weeks now, sailors from Tortuga’s repair division have devoted much of their time during this disaster relief operation to ensure the health and comfort of displaced pets.

September 4th, just after the ship moored to a pier at Naval Support Activity (NSA) New Orleans, HT1(SW) Mark Hanley and DC1(SW) Antony Graves gathered materials from the repair shop on board to construct a kennel along the levee. The facility they made soon became a popular shelter for the homeless animals of the storm.

Tortuga’s search and rescue team brought aboard more than 170 displaced citizens during this past week, providing them with food, water, medical aid and a place to sleep.

Tortuga’s makeshift kennel, named ‘Camp Milo & Otis,’ has housed as many as 90 dogs, eight cats, one rabbit, one guinea pig, a pair of parakeets and a flightless pigeon during the past week of operation.

Currently, there are 14 dogs that remain in Tortuga’s care, as many of the other pets have been taken to animal shelters in the area for extra medical attention, or been claimed by their owners upon arrival to Tortuga. The pets that Tortuga has registered have all been in the hands of professional veterinarians assigned to provide expert medical attention to the members of Camp Milo & Otis.

Dr. Kelly Crowdis and Dr. Latina Gambles, both from Tuskegee University and Christian Veterinary Missions, have treated many of the pets for infection, dehydration, malnourishment and broken bones at the Camp during the past week.

“The animals were bathed and assessed before physical interaction with the sailors,” said Dr. Crowdis. “They’ve been given immunizations, antibiotics and medications based on their medical needs.”

Dr. Crowdis added, “What these sailors have done on their own has been such a heart-warming thing. As an animal lover, it is so comforting to know that everyone cares about the animals in addition to the human lives rescued from the storm. I’m very pleased with these guys for taking the initiative to construct this kennel.”

Graves, Hanley and other members of their division have consistently bathed, fed, walked and given special attention to every dog, every day.

“We play with them,” said Hanley. “We take them out of their kennels to give them attention every day. And we’ll continue to do that for as long as our ship’s mission keeps us here.”

September 11th, the Agricultural Center at Louisiana State University donated supplies to “Camp Milo & Otis” in support of Tortuga’s efforts to help the animal victims.

”We got medical supplies, bowls, food, cages, leashes, collars, toys, cat litter and cleaning supplies from these people yesterday,” said Graves. “It’s nice to know that so many people out there have heard about what our ship is doing, and responded by donating so much to support us the best they can.”

A photo gallery of unclaimed pets is on the USS Tortuga’s web site.

As part of disaster plans, the Department of Homeland Security has also deployed Veterinary Medical Assistance Teams to provide medical care to pets and livestock, as well as provide any needed veterinary medical care for search and rescue dogs.

There are over 3,850 animals being sheltered around the state. If someone is looking for a pet they should contact their nearest Humane Society or go online to http://www.petfinder.org// . More information is also available at http://www.vetmed.lsu.edu//.

Former United States vice president Al Gore will not be facing assault charges due to allegations made by a masseuse in 2006, according to the Portland, Oregon district attorney’s office.

Molly Hagerty, 54, claimed Gore “sexually assault[ed] me in his [hotel] room.” Hagerty was called to Gore’s Portland hotel room to give him a massage. Hagerty said Gore pinned her down and “he kept trying to have sex with [her].”

Prosecutors closed the case, but after tabloid National Inquirer interviewed Hagerty they reopened the case. Hagerty refused to take a polygraph test.

Deputy DA Don Rees said there is “contradictory evidence, conflicting witness statements, credibility issues, lack of forensic evidence, and denials by Mr. Gore.”

Rees continued saying Hagerty and her attorneys were uncooperative in the investigation.

Former Salt Lake City mayor and human rights activist Rocky Anderson took some time to discuss his 2012 U.S. presidential campaign and the newly-created Justice Party with Wikinews reporter William S. Saturn.

Anderson served as mayor of Salt Lake City for eight years (2000–2008) as a member of the Democratic Party. During his tenure, he enacted proposals to reduce the city’s carbon emissions, reformed its criminal justice system, and positioned it as a leading sanctuary for refugees. After leaving office, Anderson grew critical of the Democratic Party’s failure to push for impeachment against President George W. Bush, and for not reversing policies on torture, taxes, and defense spending. He left the party earlier this year and announced that he would form a Third party.

Anderson officially established the Justice Party last week during a press conference in Washington D.C.. He proclaimed “We the people are powerful enough to end the perverse government-to-the-highest-bidder system sustained by the two dominant parties…We are here today for the sake of justice — social justice, environmental justice and economic justice.” The party promotes campaign finance reform and is attempting to appeal to the Occupy Wall Street movement. It is currently working on ballot access efforts, and will hold a Founding Convention in February 2012 in Salt Lake City.

Among other issues, Anderson discussed climate change, health care, education, and civil liberties. He detailed his successes as mayor of Salt Lake City, stressed the importance of executive experience, and expressed his views on President Barack Obama and some of the Republican Party presidential candidates. He spoke in depth about former Massachusetts governor Mitt Romney, with whom he worked during the 2002 Winter Olympics, and fellow Utahan, former governor and U.S. ambassador to China Jon Huntsman, Jr..
