AiroPlant group in EGU 2014, Vienna, Austria
Some members of the AoP group recently attended the Annual EGU General Assembly presenting some of their work.
The different studies presented as posters in different sections were: Congo basin forest carbon dynamics (Brigitte Nyirambangutse and Eric Mirindi Dusenge), CO2 effects on terrestrial biogeochemical fluxes and ecosystem functioning (Angelica Af Ekenstam, Shubhangi Lamba and Thomas B. Hasper) and Megacities: air quality and climate impacts from local and global scales (Maria Grundström).
Some highlights of the conference:
In the news: Johan Uddling was on Vetenskapsradion this morning (read and listen here). The reason was to discuss a Nature article released today by Reyes-Fox et al., about elevated CO2 extending the growing season in the fall by about a week in a grassland experiment.
Enjoy the listening and reading!

In the news: CO2 and ozone affect wheat’s nutritional quality
by Håkan Pleijel and Johan Uddling
Predicting the effects of changing levels of atmospheric gases on agricultural crops is vital to ensuring food security under global environmental change. As well as yield, impacts on the nutritional value of crops must be considered. A new study has now shown that increased ozone decreases yields and increases the proportion of protein in the grain. Conversly, elevated levels of CO2 boosts wheat yields, but it also reduces protein proportion in two different ways.
