Ecologists must join humanity's rush to the cities
02-07-2008 · EurekAlert!Cities are responsible for so many of the sustainability challenges faced by our urbanizing world, but urban ecologists can help unlock the benefits of city living, say researchers in today's issue of Science.

- Urban ecology: taking measure of the coming megacity's impact
02-07-2008 · EurekAlert!
If you are reading this, chances are that you live in a city -- one, perhaps, on its way to becoming a megacity with a population that exceeds 10 million or more. What shape could these future cities take and how will their populations meet environmental and resource challenges? An article, "Global Change and the Ecology of Cities," published in the journal Science on Feb. 8, 2008, by Arizona State University ecologist Nancy Grimm and her colleagues, addresses these questions.

- Ecologists discover city is 'uber-forest' for big owls
10-16-2007 · EurekAlert!
Charlotte has a spooky secret: the North Carolina city is home to a robust population of very large barred owls -- a species long-believed by ornithologists to require old growth forest for survival. According to ecologists doing the most extensive field study ever done on the species, the owls see urban life as an upgrade on the old woods, and Charlotteans are not at all creeped out by the big birds that share their yards.

- New survey ranks the nation's most and least sun-smart cities
05-07-2007 · EurekAlert!
Most Americans are familiar with the popular city rankings of the fattest cities, the fittest cities, the most livable cities and the most expensive cities. Now, in the first-of-its-kind survey, the American Academy of Dermatology (Academy) has identified the cities that take sun protection seriously and those that fail to make the grade despite repeated health warnings.

- Cities incite thunderstorms, researchers find
08-09-2007 · EurekAlert!
Summer thunderstorms become much more fierce when they collide with a city than they would otherwise be in the open countryside, according to research led by Princeton engineers. While thunderstorms are thought of as being purely forces of nature, the Princeton research suggests that man's built environment can radically alter a storm's life cycle.

- Where consumer culture doesn't quite reach
05-10-2007 · EurekAlert!
In the June issue of the Journal of Consumer Research, a important study by Tuba Üstüner (City University, London) and Douglas B. Holt (University of Oxford) explores how consumer culture is enacted in ramshackle neighborhoods on the peripheries of global cities. More than one billion people -- about 1/6 of the world’s total population -- live in these often illegal squatter neighborhoods on the outskirts of mega-cities in the developing world.

- Cities change the songs of birds
12-04-2006 · EurekAlert!
By studying the songs of a bird species that has succeeded in adapting to urban life, researchers have gained insight into the kinds of environmental pressures that influence where particular songbirds thrive, and the specific attributes of city birds that allow them to adjust to noisy urban environments. The findings, reported by Hans Slabbekoorn and Ardie den Boer-Visser of Leiden University, appear in the December 5 issue of Current Biology.

- Highway system drives city population declines, says Brown economist
06-13-2007 · EurekAlert!
Examining the phenomenon of suburbanization in America, Brown University economist Nathaniel Baum-Snow shows the extent to which the construction of new highways contributed to population declines in cities. He estimates that each new highway passing through a city reduces its population by about 18 percent, making the national road network a major impetus for suburbanization and sprawl of US cities. His findings are published in the Quarterly Journal of Economics.

- New fat, same old problem with an added twist?
01-16-2007 · EurekAlert!
Last month, New York City outlawed the use of partially hydrogenated oils, known as trans fats, in restaurants, a ban now under consideration in other cities, including Boston and Chicago. But novel research conducted in Malaysia and at Brandeis University shows that a new method of modifying fat in commercial products to replace unhealthy trans fats raises blood glucose and depresses insulin in humans, common precursors to diabetes. Furthermore, like trans fat, it still adversely depressed the beneficial HDL-cholesterol.
