From The Royal Botanic Gardens, Kew, The University of Western Australia, and the, Kings Park and Botanic Garden, the scientists argue that deliberately increasing the frequency of fires may lead to ecosystem degradation and loss of biodiversity.
In a paper published this month in Trends in Plant Science they acknowledge that as climate change increases the combustibility of vegetation, human lives and property are more at risk.
When people on airplanes ask Alan Newell what he works on, he tells them "flower arrangements."
He could also say "fingerprints" or "sand ripples" or "how plants grow."
"Most patterns you see, including the ones on sand dunes or fish or tigers or leopards or in the laboratory – even the defects in the patterns – have many universal features," said Newell, a Regents' Professor of Mathematics at the University of Arizona.
When a team of scientists drilling near an Icelandic volcano hit magma in 2009, they had to abandon their planned experiments on geothermal energy. But the mishap could point the way to an alternative source of geothermal power.
MADISON — Most people cross borders such as doorways or state lines without thinking much about it. Yet not all borders are places of limbo intended only for crossing. Some borders, like those between two materials that are brought together, are dynamic places where special things can happen.
For an electron moving from one material toward the other, this space is where it can join other electrons, which together can create current, magnetism or even light.
Champaign, IL – February 4, 2011 - An article in the current issue of Global Change Biology Bioenergy reviews the suitability of Agave as a bioenergy feedstock that can sustain high productivity in spite of poor soil and stressful climatic conditions accompanying climate change.
Agave, which grows successfully under hot, dry conditions, is currently used in the production of beverages, food, and fiber, and has only recently been considered a promising source of biofuel.
(Santa Barbara, Calif.) –– Siberia's Lake Baikal, the world's oldest, deepest, and largest freshwater lake, has provided scientists with insight into the ways that climate change affects water temperature, which in turn affects life in the lake. The study is published in the journal PLoS ONE today.
ANN ARBOR, Mich.---Rising carbon dioxide levels associated with global warming may affect interactions between plants and the insects that eat them, altering the course of plant evolution, research at the University of Michigan suggests.
RIVERSIDE, Calif. – Geologists drilling an exploratory geothermal well in 2009 in the Krafla volcano in Iceland encountered a problem they were simply unprepared for: magma (molten rock or lava underground) which flowed unexpectedly into the well at 2.1 kilometers (6,900 ft) depth, forcing the researchers to terminate the drilling.
While governments debate about potential policies that might curb the emission of greenhouse gases, new University of Washington research shows that the world is already committed to a warmer climate because of emissions that have occurred up to now.
MIAMI – Feb 15, 2011 – A study by scientists at the University of Miami (UM) Rosenstiel School of Marine & Atmospheric Science suggests a new way to estimate how much of the ocean's pollution is falling from the sky. The new findings can help improve scientific understanding of how toxic airborne chemicals, from the burning of fossil fuels and industrial power plants emissions, are impacting the oceans globally.
