Journal Article
Dahl, T. W., Harding, M. A. R., Brugger, J., Feulner, G., Norrman, K., Lomax, B. H., & Junium, C. K. (2022). Low atmospheric CO2 levels before the rise of forested ecosystems. Nature Communications, 13(1), Article 7616. https://doi.org/10.1038/s41467-022-35085-9

The emergence of forests on Earth (~385 million years ago, Ma)1 has been linked to an order-of-magnitude decline in atmospheric CO2 levels and global climatic cooling by altering continental weathering processes, but observational constraints on atmo...

Key traits of living fossil Ginkgo biloba are highly variable but not influenced by climate – Implications for palaeo-pCO2 reconstructions and climate sensitivity (2022)
Journal Article
Steinthorsdottir, M., Jardine, P. E., Lomax, B. H., & Sallstedt, T. (2022). Key traits of living fossil Ginkgo biloba are highly variable but not influenced by climate – Implications for palaeo-pCO2 reconstructions and climate sensitivity. Global and Planetary Change, 211, Article 103786. https://doi.org/10.1016/j.gloplacha.2022.103786

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...
