Action Levers towards Sustainable Wellbeing: Re-Thinking Negative Emissions, Sufficiency, Deliberative Democracy
Systems theory defines leverage points as places to intervene in order to change a system. Points with high impact on system behavior are notoriously hard to act upon, and indeed most policy intervention is based at the lowest level (#12 in Donella Meadows ...
EPFL2023First paleoproteome study of fossil fish otoliths and the pristine preservation of the biomineral crystal host
Anders Meibom, Jaroslaw Hubert Stolarski, Jinming Guo
Otoliths are calcium carbonate components of the stato-acoustical organ responsible for hearing and maintenance of the body balance in teleost fish. During their formation, control over, e.g., morphology and carbonate polymorph is influenced by complex ins ...
NATURE PORTFOLIO2023Reverse-engineering the locomotion of a stem amniote
Auke Ijspeert, Kamilo Andres Melo Becerra, Tomislav Horvat, Konstantinos Karakasiliotis
Reconstructing the locomotion of extinct vertebrates offers insights into their palaeobiology and helps to conceptualize major transitions in vertebrate evolution. However, estimating the locomotor behaviour of a fossil species remains a challenge because ...
2019Aragonitic scleractinian corals in the Cretaceous calcitic sea.
Anders Meibom, Jaroslaw Hubert Stolarski, Stéphane Laurent Escrig
Changes in seawater chemistry have affected the evolution of calcifying marine organisms, including their skeletal polymorph (calcite versus aragonite), which is believed to have been strongly influenced by the Mg/Ca ratio at the time these animals first e ...
Geological Soc Amer, Inc2016Redox variations and bioproductivity in the Ediacaran: Evidence from inorganic and organic geochemistry of the Corumba Group, Brazil
Stable isotope ratios combined with elemental compositions and molecular biomass data provide a powerful tool in Neoproterozoic palaeoenvironmental interpretations. Here, we report the results of an extensive organic and inorganic geochemical study perform ...
Elsevier2014Modern pollen rain and fungal spore assemblages from pasture woodlands around Lake Saint-Point (France)
Modern analogs are commonly used to investigate the relationships between modern pollen rain and the surrounding present vegetation and to improve our interpretation of fossil data. We collected modern pollen and spore rain in 18 more or less grazed and/or ...
Elsevier2012In situ search for life traces in extraterrestrial samples by synchrotron x-ray fluorescence 2D and 3D imaging - art. no. 669414
To set an optimal analytical strategy of the search for life traces, it is decisive to start their study in the preliminary examination stages of the extraterrestrial Returned Samples, once they are still stored in their original container. The relevance o ...
