No love for the lady ginkgos

Washington DC Department of Urban Forestry nips stinky seeds in the bud By Liza Lester, ESA communications officer. A male Gingko biloba in Lafayette Park, flanking the White House. Credit, Liza Lester April, 2012. As an urban arboreal companion, the ginkgo has much to recommend it. Its tall branches bring welcome summer shade, the fans of its leaves turn a lovely gold in the fall, it copes well with city pollution, lives for...

A new addition to the terrestrial nitrogen cycle

This post contributed by Lindsay Deel, a Ph.D. student in geography at West Virginia University and Intern with ESA’s journal Frontiers in Ecology and the Environment Memorizing diagrams of the nitrogen cycle – complete with all the little arrows flowing between atmospheric sources to uptake by vegetation – is a rite of passage for most undergraduate ecology students.  Now, following a new study published in the journal Nature, the...

Ecological research in images

(Click the below image to view the photo gallery.) This week, the American Museum of Natural History launched the exhibit “Picturing Science: Museum Scientists and Imaging Technologies” which explores the images produced by scientists while performing research. The images range from bug genitalia to staghorn coral (see video at the end of this post). As quoted in a recent Wired Science article, “‘A lot of people come to the museum...

The story of the fig and its wasp

Inside the rounded fruit of a fig tree is a maze of flowers. That is, a fig is not actually a fruit; it is an inflorescence—a cluster of many flowers and seeds contained inside a bulbous stem. Because of this unusual arrangement, the seeds—technically the ovaries of the fig—require a specialized pollinator that is adapted to navigate within these confined quarters. Here begins the story of the relationship between figs and fig wasps....

The evolution of beer yeasts, seedy pants and vampire bat venom-turned medicine

Beer yeasts: Researchers at Lund University in Sweden tracked the history of two yeasts—Saccharomyces cerevisiae and Dekkera bruxellensis—used in alcohol fermentation to pinpoint their role in ethanol production. They found that, around 150 million years ago, competition with other microbes, and the overall increase in sugar-rich fruits, encouraged the yeasts to withstand high ethanol concentrations—an adaptation that would allow them...
