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.
You may have noticed coverage of Crossrail at World Landscape Architect and other sites. So I thought it best to summarise what Crossrail is and who is involved.
Crossrail is the new high frequency, convenient and accessible railway for London and the South East. From 2017 Crossrail will travel from Maidenhead and Heathrow in the west to Shenfield and Abbey Wood in the east via new twin tunnels under central London. It will link Heathrow Airport, the West End, the City of London and Canary Wharf.

Toyota has unveiled “Harmony Floralscape” along the Pasadena Freeway (SR-110), this is one of the nine oversized floral designs that will appear alongside California freeways in support of the ongoing launch of the 2010 Toyota Prius hybrid vehicle. Seven of the Floralscapes will be in the Los Angeles area and two in the San Francisco area. Developed by Greenroad Media, Inc., using the company’s patent-pending “Living Pixel” technology, design images are replicated using flowers of differing varieties and colors.
The 30’x60’ Toyota Prius “Harmony Floralscapes” are comprised entirely of living seasonal flowers. The flowers used in each Floralscape – about 20,000 blooms in total – are grown by local businesses in special modular “Eco-crates” made from recycled plastic. Several different designs have been developed, and the displays will be changed and updated several times during the next four months.

Scotland has seen had a lot of green news this week with the National Parks Report being released, which recommends the reducing the numbers of members of the authority and setting up a short term National Parks Strategy Group. The government also earmarked £1m for a makeover of Urban Woods including upgrading trails and planting new trees(from The Herald). Aberdeen saw the official opening of the Scottish European Green Energy Centre(SEGEC) which will focus on marine energy, offshore wind, long distance super grid development and smart distribution grids, carbon capture and storage, renewable heat and energy efficiency.
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.
