Modeling Global Change Ecology in a High–Carbon Dioxide World
Ignite-style Session, Ecological Society of America Annual Meeting; Portland, Oregon, 11 August 2017
A Powerful New Tool to Analyze and Calibrate Earth System Models
Polynomial chaos and Bayesian compressive sensing are applied to a land surface model to understand how large numbers of tunable parameters interact and may be optimized.
Some Caves Remove Methane from the Atmosphere, New Tests Reveal
Isotopic signatures pinpoint the sinks and surprising sources of methane in widespread karst caves. Researchers suggest that this type of cave globally removes more methane than it produces.
Shedding Light on the Southern Ocean Carbon Sink
One of the world’s largest carbon sinks is still poorly understood.
U.S. and China Assess Ecosystem Effects of a Fading Cryosphere
Impacts of a Changing Cryosphere on Lakes and Streams in Mountain Regions: US-China Collaborative Workshop at Qinghai Lake; Qinghai, China, 21–27 August 2017
Ocean Wind Satellites Observe an Amazonian Drought
Satellites designed to observe ocean winds can also be used to map both forest structure and water content, allowing researchers to disentangle factors of carbon loss due to drought in the Amazon.
What Will Redwood Trees Do Without Foggy Days?
Coastal California fog—a key source of water for the iconic redwood tree—has declined by a third. Can a trace gas, carbonyl sulfide, be used to assess the effect on plant productivity?
Critical Role of Grazing Animals in an Ecosystem
Scientists model the effect of horses, cattle, sheep, and goats on local environments and global climate.
The Amazon River’s Ecosystem: Where Land Meets the Sea
What happens to plant matter on its journey down the Amazon River to the Atlantic Ocean? One research group investigated the region where river and ocean meet to fill in this part of the story.
