The gas-exchange rate between streams and the atmosphere is needed to measure in-stream ecological processes and C processing in rivers and streams. Current methods include empirical relationships to ...

A low flow of air is passed through a temperature-controlled plant chamber in order to obtain relatively large (~300-500 μ1 1-1) differences in [O2] between influx and efflux streams. These ...

The gas exchange system is responsible for getting oxygen into the blood and removing carbon dioxide as a person breathes. Breathing is also called 'ventilation' and is the movement of gases into and ...

The long-term carbon cycle operates over millions of years and involves the exchange of carbon between rocks and the Earth's surface. There are many complex feedback pathways between carbon burial, ...

University of Western Australia provides funding as a founding partner of The Conversation AU. The oceans have absorbed almost 50 % of the CO2 humans released into the atmosphere, which has driven CO2 ...

Latest findings regarding nitric oxide have the potential to reshape fundamentally the way we think about the respiratory system -- and offer new avenues to save lives. Scientific dogma has the ...

Breathe easy, for now. Scientists say our breathable air won't last forever. A new NASA-supported study warns that Earth's oxygen supply is not a permanent feature of our planet. Though we often take ...
