Soil Microbes Alter DNA in Response to Climate Change

Climate

A 10-year study of soil ecosystems has determined that microbes alter their genetic code in response to a warming climate so they can process excess carbon being absorbed by plants from the atmosphere, a team of U.S. researchers reports in the journal Applied and Environmental Microbiology.

A two degree Celsius temperature increase spurred microbes in soil ecosystems to—over many generations—tweak their DNA, amping up their respiratory systems and converting extra organic carbon in the soil to carbon dioxide.

The soil contained extra carbon because the two degree temperature increase made plants grow faster and higher; when those plants began to die, the carbon in their leaves, stems, and roots was added to the soil and taken up by the microbial community. Understanding the "black box" of carbon's fate in soil ecosystems holds important clues for better forecasting an ecosystem's response to climate change, says Georgia Institute of Technology researcher Kostas Konstantinidis, an author of the study.

"One reason that models of climate change have such big room for variation is because we don’t understand the microbial activities that control carbon in the soil," Konstantinidis said.

Following the murder of George Floyd by police in Minneapolis, people around the United States are protesting racism, police brutality, inequality, and violence in their own communities. No matter your political affiliation, the violence by multiple police departments in this country is unacceptable.

Mangroves play a vital role in capturing carbon from the atmosphere. Mangrove forests are tremendous assets in the fight to stem the climate crisis. They store more carbon than a rainforest of the same size.

From the mythical minotaur to the mule, creatures created from merging two or more distinct organisms – hybrids – have played defining roles in human history and culture. However, not all hybrids are as fantastic as the minotaur or as dependable as the mule; in fact, some of them cause human diseases.

It's a different kind of World Environment Day this year. In prior years, it might have been enough to plant a tree, spend some extra time in the garden, or teach kids the importance of recycling. This year we have heavier tasks at hand. It's been months since we've been able to spend sufficient time outside, and as we lustfully watch the beauty of a new spring through our kitchen's glass windows, we have to decide how we'll interact with the natural world on our release, and how we can prevent, or be equipped to handle, future threats against our wellbeing.
