  U BIOLOGY PROFESSOR JAMES BROWN EARNS MACARTHUR AWARD   (Site not responding. Last check: 2007-10-16)
The MacArthur Award is given biannually to an established ecologist in mid-career for meritorious research contributions to ecology.
Brown says, "It is a great honor to receive this prestigious award.
A prolific researcher with five books to his credit, Brown is known for his long-term experimental studies in the Chihuahuan Desert and for his theoretical work in macroecology and biological scaling.

Researchers at the Santa Fe Institute, including ecologist James Brown and physicist Geoffrey West, helped to develop the metabolic theory of ecology.
When Earth becomes warmer, pathogens and parasites on the planet may evolve and reproduce more rapidly, making it more difficult for humans and other animals to remain free of disease.

 Science -- Williams 276 (5309): 34
Ecologists James Brown and Brian Enquist of the University of New Mexico in Albuquerque had been butting their heads against the 1/4-power law for a long time.
Brown even suggests that a fractal circulatory system, by providing an optimum means of provisioning different body sizes, may be a major factor in the evolution of such a vast array of shapes and sizes in the living world.
West, Brown, and Enquist are now planning to test some of the model's predictions; they are also looking at whether the model can help explain other aspects of ecology and evolution, such as why life-span, age at first reproduction, and embryonic development time also fail to scale to the 1/3 power of mass.

 [No title]
In addition what ecologists sometimes do as they go beyond their immediate discipline (as opposed to what the center of gravity of the discipline ecology is) is often right on the mark.
Ecologists need to respond better than they have to these new technologies by expanding the effectiveness of their analyses of these technologies, and the extent of their scales that they allow.
Ecologists will cackle with delight when some wild species such as cardinals “does well”, that is reproduces successfully and has a general population growth and spread.

 All creatures great and small - for printer
Enquist, an ecologist at the University of Arizona in Tucson, is working to derive laws that can explain the workings of ecosystems, and the biology of their constituent organisms, in terms of those organisms' sizes - a project "as potentially important to biology as Newton's contributions are to physics", as one commentator recently put it
Brown is also intrigued that animal cells grown in a culture dish increase their metabolic rate and rate of division - as if they were aware of no longer being part of a massive unit.
Whether West, Brown and Enquist have hit the nail on the head with their fractal approach, Niklas is convinced that simple and general rules governing diverse biological phenomena lie waiting to be discovered.

 Life on the Scales: Science News Online, Feb. 12, 2005   (Site not responding. Last check: 2007-10-16)
In 2001, Brown, West, and several of their colleagues distilled their model to a single formula, which they call the master equation, that predicts a species' metabolic rate in terms of its body size and temperature.
Gillooly, Brown, and their New Mexico colleague Andrew Allen have now used these scaling laws to estimate the amount of carbon that is stored and released by different plant ecosystems.
Ecologists, physiologists, and other biologists appear to be unanimous on one point: The team's model has sparked a renaissance for biological-scaling theory.

 Nicholas School -- News & Events - current duke news releases
The ecologists decry the fact that in the face of such problems, many scientists remain preoccupied with a century-old academic debate that distracts them from the urgent need to find a new model or models that can more accurately predict diversity patterns.
Pimm is the Doris Duke Professor of Conservation Ecology at Duke's Nicholas School of the Environment and Earth Sciences, and Brown is a professor of biology at the University of New Mexico.
Pimm and Brown argue that, rather than expending so much energy tearing down each other's models, scientists should be cooperating to create a new body of knowledge and find more accurate models for predicting diversity patterns.

 Brown Tide
Brown tide not only blocks sunlight, but also has a severe toxic effect on bivalves, inhibiting their ability to eat, grow, and reproduce.
A common theory is that brown tide was able to grow better in the warm, shallow estuaries because the water was sluggish and salinity had increased to levels that favored the alga.
While brown tide may not be stimulated by these nutrients, a recent New York Sea Grant-sponsored study by Cosper and Sea Grant scholar Chris Gobler showed that increased domestic water usage is pumping more micronutrients, such as iron and selenium, into the bays, which might contribute to blooms.

The latest puff came from James Connaughton, the director of environmental quality, during last week's conference of 20 nations that met in London to attempt once again to make global warming a global priority.
At the conference, British economic minister Gordon Brown said, ''Climate change is a consequence of the build-up of greenhouse gases over the past 200 years in the atmosphere and virtually all these emissions came from the rich countries.
Brown said, ''We now have sufficient evidence that human-made climate change is the most far-reaching and almost certainly the most threatening of all the environmental challenges facing us." Connaughton's response as to what he referred as ''the extent to which humans are a factor," was, ''They may be."

They have a blue-green coloration and dark rings around their tails, making them easily distinguishable from the other iguana species on the island, which is brown and has a plain tail.

To construct their argument, James H. Brown, an ecologist at University of New Mexico, Albuquerque, Brian J. Enquist, a post-doc in his lab, and Geoffrey West, a particle physicist from Los Alamos National Laboratory, refined ideas they had put forth in a 1997 paper.
Then in 1995, Brown, long interested in biological scaling, and Enquist, who uncovered quarter-power scaling laws in plants, went in search of someone with a heartier math background to help them out.
The new model from Brown, Enquist and West is also simpler than their last.

It turns out, West says, that Rubner was on the right track in comparing surface area with volume, but that an animal's metabolic rate is determined not by how efficiently it dissipates heat through its skin but by how efficiently it delivers fuel to its cells.
Because of this trait, some ecologists have proposed planting more forests as one strategy for counteracting global warming.
Brown points out that the metabolic-scaling law may be useful by calling attention to such exceptions.
