Not a lot is known right now about how climate change affects microbial communities, according to Georgia Tech scientists. But Joel Kostka is changing that, thanks to his research into how global warming is affecting peat moss, a critical part of Earth's ecology.
Why? "It turns out that peat moss could be one of the most important plants to the global carbon cycle," says Kostka, a professor in the School of Biological Sciences and the School of Earth and Atmospheric Sciences."It could store more carbon arguably than any other plant on earth."
Kostka has a National Science Foundation grant to find out more about microbes and their relationship with plants, soil, and other aspects of the environment. Kostka's work, which is already yielding results, is the subject of ScienceMatters Season 3, Episode 8.
Some questions Kostka hopes to answer: How is climate change affecting carbon and nitrogen in our soil? Is it winnowing down microbial diversity? Is it affecting key functions microbes provide for certain plants in the environment?
Microbiomes are all the microscopic living things in a certain environment, including our bodies. When we get sick, we want to know everything about those microbiomes. There are plenty of questions to answer about the planet’s microbiome as well.
Each ScienceMatters episode includes a quiz that refers to facts mentioned in each podcast. A winner will be chosen randomly from all who submit correct answers. Winners will receive special College of Sciences gifts.
The Episode 8 quiz question:
What nutrient is pulled out of the air by plants thanks to microbes?
The winner will be announced in the following week.
