Climate gas could disrupt food chain

 

Levels of a climate cooling gas will change as carbon dioxide increases, affecting food webs along the way, said Dr Michael Steinke at a Science Media Centre press briefing today.

Microbes in the ocean produce the gas dimethyl sulphide, or DMS. It causes clouds to form above the sea, which reflect the sun’s rays away from the earth. Research suggests that plankton produce more DMS when they get hot so that clouds will cool them down. “Our work on the effect of carbon dioxide on DMS levels showed some interesting results” said Dr Steinke, from the University of Essex. “DMS production is likely to change in the future.”

DMS is responsible for the “seaside smell”. Dr Steinke discovered that plankton may use DMS when looking for prey like the way bees are attracted to fragrant flowers. “The role of DMS in climate change has been studied for years. Its role in marine ecology was unknown and this is what we are investigating.”

Marine animals including seals and birds use DMS to find food and navigate. “DMS plays an important role in oceanic food webs” said Dr Steinke. “If DMS levels change, many marine animals could find it more difficult to search for their prey.” This could have an effect on the food we eat.

Current discussions include using DMS in the “eco-engineering” of climate. Its cloud forming ability could be used to reduce global warming. However, Dr Steinke’s results show it may not be simple. “We have found that the production of DMS is much more complex than we thought and there will be plenty more surprises to come.”

Greenhouse gas from English streams

English chalk streams are less healthy than we thought and are potentially even contributing to global warming, said Dr Mark Trimmer at a Science Media Centre press briefing today.

Dr Trimmer looked at a plant that covers up to three quarters of the surface of some streams and found that it helps methane generated in the sediment beneath the plants to escape into the atmosphere. “We found similar emissions to some UK peat bogs” said Dr Trimmer from Queen Mary, University of London. “This changes our perception of the health of the ecosystem and it indicates another disadvantage of agriculture.”

Over 90% of the methane emissions from the river Frome in Dorset that reach the atmosphere do so via the stems of water crowfoot. The plant also causes a build-up of sediment from neighbouring farmland, which aids the production of methane by bacteria in the stream.

“Chalk streams are a British specialty habitat and a priority under the UK’s Biodiversity Action Plan. They have a high status but there is growing concern about their ecological decline.”

Dr Trimmer estimates that the total area of chalk streams in the UK is around 20 km2. The situation he observed in Dorset is likely to be widespread. More research is needed to understand methane emissions from chalk streams fully. “There is obvious climatic concern for any unquantified potential source of methane.”
