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!

A review this week by Wikinews of US Consumer Financial Protection Bureau (CFPB) complaints about student loans in the United States shows Sallie Mae leads all lending institutions in complaints. Of the 4,851 complaints dating back to March 2012 when the CFPB first began collecting student loan data, 2,262 or 46.6% of all complaints were about the lender. US Federal Reserve data from 2010/2011 shows Sallie Mae is the nation’s largest student loan lender, responsible for 25% of the market

The other major lenders in this space include Wells Fargo, JP Morgan Chase, PNC, and Discover. In complaints, AES/PHEAA came in second with 546, or 11.3% of all complaints. Wells Fargo, Citibank and JPMorgan Chase each had between 5% and 7.5% of all complaints, totaling 918 complaints between them. 78 other lending institutions round out the list of organizations with complaints filed against them for student loans.

Few of the complaints originate from people with problems with federal student loans. Less than 1%, 35 total, are for these types of loans, with Sallie Mae accounting for the bulk of complaints with 17 total. 14 other lending institutions have 3 or fewer complaints. For non-federal student loans, Sallie Mae is still the leader for complaints, with 2245 or 46.6% of all non-federal student loan complaints.

The Consumer Financial Protection Bureau sorts complaints into three issues: Problems when you are unable to pay, Repaying your loan, and Getting a loan. None of the federal loans had complaints about getting a loan. For non-federal loans, 65.5% of the 4,816 complaints related to loan repayment. Sallie Mae led in total complaints in this category with 1467. They were followed by AES/PHEAA with 356, Wells Fargo with 231, Citibank with 201, Discover with 158, JPMorgan Chase with 154, ACS Education Services with 143, and KeyBank NA with 116. CFPB says loan repayment issues include a basket of claim types including “fees, billing, deferment, forbearance, fraud, and credit reporting.” Problems when you are unable pay accounts for 30.8% of the complaints. Sallie Mae had 698 complaints. They were followed by AES/PHEAA with 181, JPMorgan Chase with 106, Wells Fargo with 104, Citibank with 70, and KeyBank NA with 58. Many of the complaints are, according to the CFPB, because borrowers have difficulty getting deferrments on loan repayment as a result of being unable to find employment.

The total complaints against Sallie Mae for September of this year is 2 fewer than the same time last year. The company’s performance this year compared to last year has been mixed. March and June numbers were down over 150 complaints from the same month a year before. April, May, July and August all saw increases of 17–43. Of the top six lenders by volume of complaints, only AES/PHEAA and Citibank saw drops every month between March and September from the total volume in the previous year. Wells Fargo had a gain of 1 in August and 6 in May from the previous year. JPMorgan Chase had a difference of 0 from the same month last year for April, 3 more this year for May, and 4 more for August. Discover saw an increase every month from the same period last year except for September. When the total complaints differences from year to year for March to September are counted, this year has 571 fewer complaints against the top six lenders.

Most, 1470, of the complaints against Sallie Mae were closed with explanations. 10.2% were closed with monetary relief. 7.7% were closed with non-monetary relief. 2.1% were closed with relief and 12.1% were closed without relief. AES/PHEAA’s complaint closure picture was much different. 40.1% of AES/PHEAA’s 546 complaints were closed with non-monetary relief, 35.3% were closed with explanations and 21.2% were closed without relief. Of the eight lending institutions with 100 or more complaints filed against them, Discover was the institution most likely to result in a closure with monetary relief with 12.9% of all their closures ending this way. Citibank was the institution with the highest percentage of closures ending with no relief at 26.0%.

Complaints over student loan lenders were geographically distributed, coming from 3,447 different zip codes. The largest cluster of complaints is for 20001, a Washington D.C. zip code with 10 complaints originating from there. 07950, the zip code for Morris Plains, New Jersey, and 37013, the zip code for Antioch, Tennessee, each had 8 complaints originating from them. Zip codes for Patchogue, New York; Philadelphia, Pennsylvania; Washington D.C.; and Arlington, Virginia each had 7 complaints originating from them. By volume of complaints by state, New York led with 497, with California second with 467, Pennsylvania third with 303, Florida fourth with 288 and Ohio fifth with 219 complaints. US Territories largely occupied the bottom spots. The Northern Marianas Islands, with a population of around 50,000, had 1 complaint. The U.S. Armed Forces – Pacific had 3. North Dakota and U.S. Armed Forces – Europe had 5 complaints each. South Dakota had 7. Wyoming had 8. Puerto Rico and Alaska had 9 each. Rounding out the bottom five states by volume of complaints, Mississippi had 11.

With the possibility of a United States government federal shutdown looming on October 1, student loans may be impacted because of potential for an automatic increase in interest rates.

The five largest United States banks need a total of US$74.6 billion in extra funds to increase their cash reserves, according to so-called “stress tests” conducted by regulators to determine whether the banks have enough capital to survive the ongoing recession.

“Our hope with today’s actions is that banks are going to be able to get back to the business of banking,” said Timothy Geithner, the US Treasury Secretary.

The results of the stress-test determined that Bank of America was the bank most at risk, needing $33.9 billion. Wells Fargo will require an additional $13.7 billion, while GMAC needs $11.5 billion.

Seven other banks failed the “stress test”, including: Citigroup, Morgan Stanley, Regions Financial, SunTrust Banks, KeyCorp, Fifth Third Bancorp, and PNC Financial Services.

Nine other banks that underwent stress tests, such as Goldman Sachs, JPMorgan Chase, Bank of New York Mellon, MetLife, American Express, State Street, BB&T, US Bancorp and Capital One Financial, were found to have enough capital in case the recession deepens.

Those banks that need extra money will be set a June 8 deadline to draw up their plans to raise the additional capital and have regulators approve them.

New South Wales Police, in connection with the NSW Roads and Traffic Authority, Tow Truck Authority and Centrelink (the agency responsible for providing income support) conducted random checks on tow trucks on Thursday. The checks were carried out in Bankstown, a suburb in Sydney’s South-West.

According to police, 50 tow trucks were pulled over during the operation, coined “Operation Hook” between 8:30 a.m. AEST and 4 p.m. Of those, 26 were directed to report to a vehicle inspection facility for further investigation.

Police issued 70 infringement notices (fines) during the operation. 11 were for being unlicensed to conduct business as a tow truck driver or business, and 13 for having incorrectly secured loads. 17 vehicles were issued defect notices as part of the operation.

Tow truck operators (business owners) are required to make a payment of AUD$770 per year to the NSW government, while drivers are charged $152 per year for their licence. An additional charge for tow truck number plates of $292 per year also applies.

The maximum penalty for operators not being licensed correctly is $11,000 or 12 months imprisonment, drivers without the correct licence can be fined $5,500 or sentenced to 6 months.

Farming in urban areas has been banned in the latest turn in the Zimbabwean government’s ‘crackdown’ on the country’s poor.

Zimbabwe is in the grip of a chronic drought and with food supplies running low, thousands fear starvation after they were told they could no longer supplement their food supply with crops grown themselves. A police spokesman told a UN news agency that they were under government instruction to prevent urban farming.

Police spokesman Wayne Bvudzijena said “a lot of harm is being done to the environment. Why can’t those who want to cultivate crops go to rural areas, where people are being allocated farms under the land reform programme?”

People living in urban areas had taken to growing their staple crop – maize – and other grains in patches of land near their houses. Much of the land being used had already been earmarked for cultivation, but the police have been told to ignore any such designations.

A non-governmental organisation, Environment Africa, agreed with some of the policy. “We totally understand and appreciate the need for urban people to supplement their incomes, but they should not do it the wrong way. Ideally, farming should be done on farms, not in towns. What we have witnessed is an irreparable damage to the environment, which will certainly have dire consequences for our beloved cities,” said an official.

A spokesman for the opposition — the Movement for Democratic Change (MDC) — said that while planting on undesignated land, especially amid a maze of houses in townships, was not something they could approve, planting on designated areas should be allowed.

Such urban farming could produce up to 100,000t of grain in a good year, the spokesman added. He believes the government aims to drive urban people — who are often MDC supporters — out into the countryside, with the promise of getting land under the “reform program”.

As international concern about Zimbabwe grows, Kofi Annan plans to send a special envoy to assess the situation. However, he has not scheduled a date for the visit.
