Pollen and spores as biological recorders of past ultraviolet irradiance (2016)
Journal Article
Jardine, P. E., Fraser, W. T., Lomax, B. H., Sephton, M. A., Shanahan, T. M., Miller, C. S., & Gosling, W. D. (in press). Pollen and spores as biological recorders of past ultraviolet irradiance. Scientific Reports, 6(39269), https://doi.org/10.1038/srep39269

Solar ultraviolet (UV) irradiance is a key driver of climatic and biotic change. Ultraviolet irradiance modulates stratospheric warming and ozone production, and influences the biosphere from ecosystem-level processes through to the largest scale pat...

Shedding light on sporopollenin chemistry, with reference to UV reconstructions (2016)
Journal Article
Jardine, P. E., Abernethy, F. A., Lomax, B. H., Gosling, W. D., & Fraser, W. T. (2017). Shedding light on sporopollenin chemistry, with reference to UV reconstructions. Review of Palaeobotany and Palynology, 238, https://doi.org/10.1016/j.revpalbo.2016.11.014

Sporopollenin, which forms the outer wall of pollen and spores, contains a chemical signature of ultraviolet-B flux via concentrations of UV-B absorbing compounds (UACs), providing a proxy for reconstructing UV irradiance through time. Although Fouri... Read More about Shedding light on sporopollenin chemistry, with reference to UV reconstructions.

A novel root-to-shoot stomatal response to very high CO2 levels in the soil: electrical, hydraulic and biochemical signalling (2016)
Journal Article
Lake, J. A., Walker, H. J., Cameron, D. D., & Lomax, B. H. (2017). A novel root-to-shoot stomatal response to very high CO2 levels in the soil: electrical, hydraulic and biochemical signalling. Physiologia Plantarum, 159(4), 433-444. https://doi.org/10.1111/ppl.12525

Investigations were undertaken in the context of the potential environmental impact of Carbon Capture and Storage (CCS) transportation in the form of a hypothetical leak of extreme levels of CO2 into the soil environment and subsequent effects on pla...

Chemotaxonomy as a tool for interpreting the cryptic diversity of Poaceae pollen (2016)
Journal Article
Julier, A. C., Jardine, P. E., Coe, A. L., Gosling, W. D., Lomax, B. H., & Fraser, W. T. (2016). Chemotaxonomy as a tool for interpreting the cryptic diversity of Poaceae pollen. Review of Palaeobotany and Palynology, 235, https://doi.org/10.1016/j.revpalbo.2016.08.004

The uniform morphology of different species of Poaceae (grass) pollen means that identification to below family level using light microscopy is extremely challenging. Poor taxonomic resolution reduces recoverable information from the grass pollen rec... Read More about Chemotaxonomy as a tool for interpreting the cryptic diversity of Poaceae pollen.

Quality not quantity: organic matter composition controls of CO₂and CH₄fluxes in neotropical peat profiles (2016)
Journal Article
Hoyos-Santillan, J., Lomax, B. H., Large, D., Turner, B. L., Boom, A., Lopez, O. R., & Sjögersten, S. (2016). Quality not quantity: organic matter composition controls of CO₂and CH₄fluxes in neotropical peat profiles. Soil Biology and Biochemistry, 103, https://doi.org/10.1016/j.soilbio.2016.08.017

Tropical peatlands represent an important source of carbon dioxide (CO₂) and methane (CH₄) to the atmosphere. However, we do not know where in the peat profile these gases are produced and how controlling factors, such as substrate quality, which can...
