FTIR spectra from grass pollen: A quest for species-level resolution of Poaceae and Cerealia-type pollen grains (2023)
Journal Article

Palynological analysis based on spore and pollen morphology is well established in the field of palaeo-environmental reconstruction but is currently not fully exploited for understanding the history and development of cereal cultivation due to diffic...

Response to Comment on "Dying in the Sun: Direct evidence for elevated UV-B radiation at the end-Permian mass extinction" (2023)
Journal Article

Seddon and Zimmermann have raised questions about the evidence for increased UV-B flux across the end-Permian mass extinction (EPME) that was presented in our recent study, specifically regarding the measurement of UV-B-absorbing compound (UAC) level...

Dying in the Sun: Direct evidence for elevated UV-B radiation at the end-Permian mass extinction (2023)
Journal Article

Land plants can adjust the concentration of protective ultraviolet B (UV-B)-absorbing compounds (UACs) in the outer wall of their reproductive propagules in response to ambient UV-B flux. To infer changes in UV-B radiation flux at Earth's surface dur... Read More about Dying in the Sun: Direct evidence for elevated UV-B radiation at the end-Permian mass extinction.
