Boulder citizens, youth give high marks to city in survey
Jan 5th
2011 Community Survey results available
Results of the 2011 Community Survey that was conducted this fall are now available online and will be presented to City Council at its regularly scheduled meeting at 6 p.m. on Tuesday, Jan. 10, 2012. Copies of the report are also available in the Main Library, 1001 Arapahoe Ave.
In September and October, surveys were mailed to more than 3,000 households and more than 400 University of Colorado students living in on-campus dormitories. Surveys could also be completed online and were available in Spanish. A total of 971 surveys were returned, which resulted in a 33 percent response rate. That is considered a good rate of return.
The survey asked people about their priorities for the city, quality of life, and their overall satisfaction with government services. Survey responses indicated:
- Perceptions of the quality of life, quality of neighborhoods and the sense of community in Boulder remain high;
- Employment and business related ratings were also high, with 77 percent of respondents rating Boulder as “very good’ or “good” as a place to work, and 69 percent rating Boulder as “very good” or “good” as a place to do business; and,
- Respondents’ priorities for City Council included energy, housing and business development.
The survey results also provided information about public participation and how people would like to obtain information about meetings, issues and programs:
- Approximately 25 percent of respondents said that they had attended a public meeting about city matters in the last year, and about 25 percent had watched a City Council meeting on the city’s municipal Channel 8.
- The Camera (72%), direct mailings (65%), and the city’s website (55%) – www.bouldercolorado.gov – were the most common sources of public information from the city.
The 2011 survey included additional outreach to Spanish speakers through community organizations, and 43 completed surveys were received. Priorities and concerns for these respondents included safety, affordable shopping, housing, adult education opportunities and activities for youth.
A slightly revised survey was also distributed to Boulder youth to help the city determine their concerns and needs. A total of 234 returned surveys indicated that youth priorities include homelessness, improving activities for young people, jobs, discrimination, bike safety and facilities, and the environment.
Survey results will be used to inform the budget process, plan for future projects, develop community outreach and various other ways to help make Boulder a better place to live and work. A complete list of results, responses and methodologies is available at www.BoulderColorado.gov > Hot Topics > 2011 Community Survey Results.
The survey was conducted by Boulder-based National Research Center Inc. Results were weighted and the margin of error is plus or minus three percentage points from the information that would have been obtained if all Boulder adults were surveyed.
CU Boulder study: fossils show evolution of bug hearing

FROM COLORADO HINT AT ORIGIN OF INSECT HEARING
How did insects get their hearing? A new study of 50-million-year-old cricket and katydid fossils sporting some of the best preserved fossil insect ears described to date are helping to trace the evolution of the insect ear, says a new study involving the University of Colorado Boulder and the University of Illinois at Chicago.
According to University of Colorado Museum of Natural History paleontologist Dena Smith and University of Illinois Professor Roy Plotnick, who collaborated on the new study at the National Evolutionary Synthesis Center, or NESCent, in Durham, N.C., insects hear with help from some very unusual ears.
Grasshoppers have ears on their abdomens. Lacewings have ears on their wings. The ears of the tachinid fly are tucked under the chin. “Insects have ears on pretty much every part of their body except on their head proper,” Plotnick said.
Insects have evolved ears at least 17 times in different lineages, said Smith, also an assistant professor in CU-Boulder’s geological sciences department. Smith and Plotnick are trying to figure out when different insects got their ears, and whether predators may have played a role.
Modern insects use their ears to tune in to each other’s chirps, trills and peeps. Think of the chorus of crickets, or the love songs of cicadas. But many species can also pick up sounds beyond the range of human hearing, such as the high-pitched sonar of night-hunting bats, according to Smith and Plotnick.
Crickets, moths and other flying insects have ultrasound-sensitive hearing and can hear bats coming, diving or swerving in midflight to avoid being eaten. Insects that evolved such supersensitive hearing would have had a crucial survival advantage, the researchers said.
“The big evolutionary trigger for the appearance of hearing in many insects is thought to be the appearance of bats,” Plotnick said. “Prior to the evolution of bats we would expect to find ears in relatively few insects, but after that we should see ears in more insect groups,” he explained.
Did insect ears get an upgrade when bats came to be? Before this study the fossil evidence for insect hearing was too poorly preserved or scantily described to know for sure, according to the researchers.
To find out, Plotnick and Smith turned to remarkably well-preserved fossils from a series of lake deposits in Wyoming, Utah and Colorado known as the Green River Formation, where some of the earliest bats are found.
Roughly 50 million years ago, fine-grained sediment covered and buried the animals that lived there and managed to preserve them in exquisite detail. “You can see every tiny feature down to the veins in their wings and the hairs on their legs,” said Smith, who has been studying Green River fossils for more than 15 years.
For this study, the researchers examined fossils from a Green River site in Colorado, focusing on crickets and katydids, which have ears on their front legs, just below their knees.
The team scoured more than 500 museum drawers of Green River fossils for crickets and katydids with intact front legs, looking for evidence of ears. “You can just make them out with the naked eye,” Plotnick said. “They look like the eye of a needle.”
In crickets and katydids living today, the ear is a tiny oval cavity with a thin membrane stretched over it that vibrates in response to sound, much like our own eardrum.
The fossil ears measured half a millimeter in length, and were virtually identical in size, shape and position to their modern counterparts. The findings suggest that this group of insects evolved their supersensitive ultrasonic hearing long before bat predators came to be, the researchers say. “Their bat-detecting abilities may have simply become apparent later,” Smith said. “The next step is to look for ears in other insect groups.”
The study appears in this month’s issue of the Journal of Paleontology. NESCent is a nonprofit science center dedicated to cross-disciplinary research in evolution and is jointly operated by Duke University, the University of North Carolina at Chapel Hill and North Carolina State University, with funding from the National Science Foundation.

CU Boulder KAT house burns over break, resources available
Dec 20th
KAPPA ALPHA THETA FIRE
The University of Colorado Boulder is assisting the Kappa Alpha Theta sorority in the aftermath of a fire late Monday night that severely damaged the sorority’s house at 1333 University Ave., adjacent to the CU-Boulder campus.
No sorority members were in the house at the time of the fire, as the university is on winter break. Sixty-two chapter members were scheduled to live in the house for the upcoming spring semester.
The house mother for Kappa Alpha Theta was safely evacuated from the house, which was severely damaged and is currently uninhabitable. Boulder police and fire officials are investigating the cause of the blaze.
CU officials from the offices of Student Affairs, Greek Life, Victim Assistance and Counseling and Psychological Services are prepared to work with sorority officials to reach out to chapter members to provide resources and services that include housing, counseling services, and course materials and equipment for classes.
Members of Kappa Alpha Theta or their families needing university assistance should contact the Office of Student Affairs at 303-492-8476 or CU-Boulder’s Office for Greek Life at 303-492-6359.
Other resources are available through the Office of Victim Assistance at 303-492-8855, the Office of Counseling and Psychological Services at 303-492-6766 and the Office of Psychological Health and Psychiatry at Wardenburg Health Center at 303-492-5654.
