End-of-dry-season CO2 pulses recur each year in the atmosphere above the Australian continent, a discovery made by an international research team led by environmental physicist Prof. Dr André Butz of Heidelberg University.

It Isn’t the Picky Eaters that Drive Soil Microbial Metabolism
How do microbes in soil communities interact to release nutrients from material in the soil? Researchers have discovered that microbes able to break down one type of available food, chitin, are critical for the community’s success but do not necessarily grow the fastest. Instead, species with the ability to use a wide range of food sources produced by other members of the community become the most abundant. The researchers also found that individual microbes can change their behavior when grown alone or in the community.
Starting small to better understand key steps in the carbon cycle
Soil microbes decompose organic matter into simple carbon compounds – what soil conditions do these microbes prefer and where do they work most efficiently?
NSF Announces New Sci-Tech Center to Study Ocean Chemical-Microbe Network and Climate Change
A new Science and Technology Center, which the National Science Foundation (NSF) announced today, will conduct transformative research, along with education and outreach, to promote a deeper understanding and appreciation of the chemicals and chemical processes that underpin ocean ecosystems.
FSU researchers find La Niña increases carbon export from Amazon River
When La Niña brings unusually warm waters and abnormal air pressure to the Pacific Ocean, the resulting weather patterns create an increase in the carbon export from the Amazon River, new research from Florida State University has found.
Rutgers Expert Available to Discuss Viral ‘Pandemics’ in Oceans
New Brunswick, N.J. (April 6, 2021) – Rutgers University–New Brunswick microbial oceanographer Kay D. Bidle is available for interviews on the persistent and profound impact of viral infections on algae in the oceans. These infections influence the Earth’s carbon cycle, which helps…
Healing a wounded world
Brooke Eastman studies how acid rain impacts forest health. She is committed to highlighting forests’ role in mitigating climate change.
Fishes Contribute Roughly 1.65 Billion Tons of Carbon in Feces and Other Matter Annually
Scientists have little understanding of the role fishes play in the global carbon cycle linked to climate change, but a Rutgers-led study found that carbon in feces, respiration and other excretions from fishes – roughly 1.65 billion tons annually – make up about 16 percent of the total carbon that sinks below the ocean’s upper layers.
Remote Sensing Expert: World’s Largest Lakes Reveal Climate Change Trends
Mike Sayers, Michigan Tech Research Institute research scientist, is available to speak to using remote sensing to discover how climate change affects the world’s largest freshwater lakes, which account for 50% of the Earth’s surface freshwater. Sayers’ NASA-funded research shows how…
Nate McDowell: Then and Now / 2010 Early Career Award Winner
Nathan McDowell, a staff scientist at the U.S. Department of Energy’s Pacific Northwest National Laboratory, used his 2010 Early Career Award to study how trees survive and die during drought because vegetation plays a major role in the global carbon cycle.
Breaking Down Wood Decomposition by Fungi
SUMMARYThrough a combination of lab and field experiments, researchers have developed a better understanding of the factors accounting for different wood decomposition rates among fungi. The new findings reveal how an understanding of fungal trait variation can improve the predictive…
Ocean’s ‘biological pump’ captures more carbon than expected
Scientists have long known that the ocean plays an essential role in capturing carbon from the atmosphere, but a new study from Woods Hole Oceanographic Institution (WHOI) shows that the efficiency of the ocean’s “biological carbon pump” has been drastically underestimated, with implications for future climate assessments.
Beneath the Ice: FSU researchers find newly uncovered Arctic landscape plays important role in carbon cycle
As the ice sheet covering most of Greenland retreats, Florida State University researchers are studying the newly revealed landscape to understand its role in the carbon cycle.
