Proxy reconstruction of ultraviolet-B irradiance at the Earth's surface, and its relationship with solar activity and ozone thickness (2019)
Journal Article

Solar ultraviolet-B (UV-B) irradiance that reaches the Earth’s surface acts as a biotic stressor and has the potential to modify ecological and environmental functioning. The challenges of reconstructing ultraviolent (UV) irradiance prior to the sate...

The modern pollen-vegetation relationships of a tropical forest-savannah mosaic landscape, Ghana, West Africa. (2017)
Journal Article

Transitions between forest and savannah vegetation types in fossil pollen records are often poorly understood due to over-production by taxa such as Poaceae and a lack of modern pollen–vegetation studies. Here, modern pollen assemblages from within a... Read More about The modern pollen-vegetation relationships of a tropical forest-savannah mosaic landscape, Ghana, West Africa..

A novel root-to-shoot stomatal response to very high CO2 levels in the soil: electrical, hydraulic and biochemical signalling (2016)
Journal Article

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

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 CO?and CH?fluxes in neotropical peat profiles (2016)
Journal Article

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...

Effects of elevated soil CO2 concentration on growth and competition in a grass-clover mix (2016)
Journal Article

To investigate potential environmental affects in the context of carbon dioxide (CO2) leakage from Carbon Capture and Storage (CCS) schemes. The ASGARD (Artificial Soil Gassing and Response Detection) facility was established, where CO2 can be inject...

Palaeoproxies: botanical monitors and recorders of atmospheric change (2015)
Journal Article

The integration of plant and Earth sciences offers the opportunity to develop and test palaeobotanical monitors and recorders (palaeoproxies) of past atmospheric change that are understood from a mechanistic perspective, with the underpinning respons...

Leaf energy balance modelling as a tool to infer habitat preference in the early angiosperms (2015)
Journal Article

Despite more than a century of research, some key aspects of habitat preference and ecology of the earliest angiosperms remain poorly constrained. Proposed growth ecology has varied from opportunistic weedy species growing in full sun to slow-growing...
