Sean Hammond and Karl Niklas have published a paper in the August 2009 edition of American Journal of Botany presenting an algorithm that could be used to predict plant communities. The algorithm known as spatially explicit, reiterative algorithm, or SERA explores whether changes occurring in plant communities, such as self-thinning and the competitive displacement of one species by another, can be attributed to the characteristics of the individual plants that comprise the community.
“Remarkably, our model predicts the behavior of real plant populations, and thus suggests to us that many ‘complex’ ecological interactions emerge as a result of a few very ‘simple’ processes,” commented Dr. Niklas. SERA may be very useful in predicting changes in community development and composition as environmental and climatic variability increases.
Despite the dangers, biking is New York City’s “fastest growing mode of transportation,” says City Transportation Commissioner Janette Sadik-Khan, who herself bikes to work in lower Manhattan, about a mile from her Greenwich Village home.
The number of cyclists has jumped by 80 percent in the past decade — to 185,000 among the more than 8 million city denizens.
Suzanna Dennis surveys the fruits of months of tender care: a vegetable garden of vigor, health and bounty……………… All this can be found in the meager 9 by 5 feet of a sidewalk bed on Capitol Hill that, until Dennis transformed it this spring, held the rotting stump of a fallen street tree. “I saw this space lying fallow,” she said. “I decided to turn it into a vegetable garden.”
The first set of small-scale urban wind turbines in the U.S. are being installed in Portland atop the new Twelve|West tower this week. Today the Hoffman Construction should raise the final blades to the top of Twelve|West a 22 storey office and residential building. Zimmer Gunsul Frasca Architects LLP, which designed the tower, has moved its corporate headquarters to the building.
Glenn Murcutt, the Pritzker prize-winning architect has spoken out about the new and revised architecture and landscape architecture at Newcastle University. Murcutt, particlarly points out that he is amazed at the cutting down of trees and the change in plant material used on the site. He goes on to online that the design process should have been different and consultation with the original architects and masterplanners.
The Bidhannagar Municipality had last year proposed that the state tourism department develop the 20-sqkm wetland area almost twice the size of Salt Lake falling under its jurisdiction as an eco-tourism centre. However, no initiative has been taken since then to take the plan forward. The proposal had come in the wake of promoters allegedly trying to construct buildings in parts of the wetlands.
