1.2 Mkr from the Danish Research Agency (DFF) to study the impact of land plants
The DFF-ERC programme has awarded 1.2 Mkr to a project, entitled: PlantImpact – Linking mesocosm experiments to global biogeochemical models. The project will open 1 postdoc position beginning in the fall 2018. We are seeking candidates with at least one strong peer-reviewed publication and experience with theoretical modeling. A background in plant ecology is helpful and … Read More

Publication: Animals set the direction for Earth’s carbon cycle
In a new paper led by Richard Boyle, we show that the emergence of animal ecosystems – and more specifically the animal burrowing and sediment mixing – acted to dampen the magnitude and duration of instabilities in the Earth’s long term carbon cycle. The paper is published in Geobiology. Read the Rich’s comment on the … Read More

Beginning in January 2018, Magnus A. R. Harding will continue working in the group now as a research assistant. Magnus’ main focus will be to extend ongoing studies of the chemical composition of fossil plant leaves.
New paper in press: Ocean redox conditions between the Neoproterozoic Snowballs
A new paper on the redox conditions in the oceans after the Sturtian and before the Marinoan ‘Snowball’ glaciations is now press in Precambrian Research. Our results suggest that oceans remained largely anoxic after the Sturtian glaciation and that something else triggered oxygenation of the Ediacaran oceans after the Marinoan glaciation. This ‘something’ could be due to the way animals affect the global … Read More
