OU researchers observing and analyzing ecosystem responses to global change received a $3 million grant from the U.S. Department of Energy.
The OU Institute for Environmental Genomics has partnered with researchers from Michigan State University, the University of Florida and the Georgia Institute of Technology to study microbial changes at two sites, said Jizhong Zhou, Institute for Environmental Genomics director.
“We will use metagenomic technology such as high-throughput sequencing and gene chips to look at how communities change,” said Zhou, microbiology professor.
The researchers will use mathematic tools to simulate and predict changes in the future, focusing on two sites — one in Oklahoma and one in Alaska.
“We have been performing global warming experiments in Oklahoma for 12 years,” said Yiqi Luo, OU ecologist and professor of botany and microbiology.
The researchers simulate global warming by hanging heaters 1.5 meters above the ecosystems, raising the temperature by 3 to 4 degrees Fahrenheit. “This experiment has found that global warming affects plants in a global community,” Luo said.
Humans release 10 billion tons of carbon dioxide, otherwise known as greenhouse gases, in the atmosphere, which causes global warming. Scientists predict global temperature will increase by 4 degrees Fahrenheit, so projects the Institute for Environmental Genomics are conducting aim at trying to understand how microorganisms regulate the carbon cycle, Luo said.
The first thing Zhou and his lab plan on doing with this $3 million grant is employing the high-throughput sequencing technology to observe microorganism diversity in order to understand the effects of global warming on diversity.
Then, they will set up lab experiments to study how warming affects microorganism functionality. They also will monitor how plants respond to global warming in the field.
Zhou’s lab invented the original GeoChip, an advanced technique used to detect microbial genes. This device enables Zhou and members of his lab to detect which microorganisms are in the ecosystem and what their roles are.
“We will use the information gathered from the sequencing to develop the next generation of the GeoChip to monitor the responses of the community under different conditions,” Zhou said.
“We are pioneers in this field,” Zhou said. “We invented this technology and we are the only lab in the world that has it.”
Zhou and Luo worked together to write the proposal to the Department of Energy a couple of years ago when a competition for carbon cycle research was created.
In addition to their research, the professors focus on training the next generation of scientists to apply for grants.
Kai Xue, one of the post-doctoral students working for the Institute, is learning how to write proposals. His focus, microecology, is just one of the many different backgrounds researchers in this project have.
Zhili He, OU adjunct professor and synthesist for the Institute, is more focused on gene development.
Liyou Wu, another researcher on the project and an adjunct professor in the Department of Botany and Microbiology, coordinates the research efforts across the five labs spread across the nation.
“This project is very important and we are hopefully computing something that will resolve this problem [of global warming on ecosystems] in the future,” Wu said.

A perfect example of why the US is so far in debt.

?what? We are in debt due to an military conflicts in Afghanistan and Iraq, an unfunded Medicare prescription plan, and other factors. We are falling behind in the global economy partly because we are not pushing more R&D.
Check out research/studies done by R.E.Dunlap and colleagues.

We are not in debt because of a war. Hear me out, the military is paid whether or not we are at war. We expend munitions in training whether or not we are in battle. We fly our planes daily whether or not we are at war. We are in debt because of unfunded liabilities and the ever increasing debt ceiling that congress has kept raising for so many years. Mark my words, to get out of this debt we will have to cut all social welfare programs, print money (monetize the debt, which we are doing now), and produce more as a nation that we can sell to overseas markets so that we can pay them back all the money we borrowed. It will be difficult and it won't be fun. But this kind of junk spending is sending us further in debt and it will lengthen our upcoming depression.

Goodness, talk about begging the question & missing the point all together. "Humans release 10 billion tons of carbon dioxide, otherwise known as greenhouse gases, in the atmosphere, which causes global warming." This is by no means scientifically proven! There is no statistically significant evidence that backs this up! BUT, the author says it, so it must be true... Then the author goes on to say that Scientists predict global rises in temperatures of 4 degrees? That's asinine. A few scientists who are not climatologists might speculate that & Al Gore might preach it, but that is by far not the scientific consensus. The real story is not about researching global warming, it's about the GeoChip - if only we knew more about it than 1 sentence... I'm sure this is written by a student, so my recommendation is aim for truth, not salaciousness - this is journalism, not the tabloids.
