Journal Article
Liu, F., Peng, H., Marshall, J. E., Lomax, B. H., Bomfleur, B., Kent, M. S., …Jardine, P. E. (2023). Dying in the Sun: Direct evidence for elevated UV-B radiation at the end-Permian mass extinction. Science Advances, 9(1), Article eabo6102. https://doi.org/10.1126/sciadv.abo6102

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.

Low atmospheric CO2 levels before the rise of forested ecosystems (2022)
Journal Article

The Ginkgoales, including the ‘living fossil’ Ginkgo biloba, are an important group for stomata-based palaeo-pCO2 reconstructions, with long evolutionary lineages and an extensive, abundant fossil record. The stomatal proxy for palaeo-pCO2 can improv...

Journal of Paleolimnology, 67(1), 75-93. https://doi.org/10.1007/s10933-021-00222-9

Lake sediments are important archives of past climate variability and lake responses to climate. In order to accurately infer past climates, it is necessary to understand, and account for, the ecological processes that affect the record of indicators...

Litterfall is a critical link between vegetation and soils by which nutrients are returned to the soils, thus the amount and pattern of litterfall regulates nutrient cycling, soil fertility and primary productivity for most terrestrial ecosystems. We... Read More about Temporal changes in litterfall and potential nutrient return in cocoa agroforestry systems under organic and conventional management, Ghana.
