Plant responses to simulated carbon capture and transport leakage: the effect of impurities in the CO2 gas stream (2018)
Journal Article

To deliver an effective transition from a carbon-based 24 to a carbon-free energy market, bridging technologies are required. One such possibility is the use of carbon capture and storage, (CCS). However, before such innovations can be rolled out a k... Read More about Plant responses to simulated carbon capture and transport leakage: the effect of impurities in the CO2 gas stream.

Changes in CO2 during ocean anoxic event 1d indicate similarities to other carbon cycle perturbations (2018)
Journal Article

Past greenhouse intervals of the Mesozoic were repeatedly punctuated by Ocean Anoxic Events (OAEs), major perturbations to the global carbon cycle and abrupt climate changes that may serve as relevant analogs for Earth’s greenhouse gas-forced climate...

Nutrient limitation or home field advantage: does microbial community adaptation overcome nutrient limitation of litter decomposition in a tropical peatland? (2018)
Journal Article

Litter decomposition is an important control on carbon accumulation in tropical peatlands. Stoichiometric theory suggests that decomposition is regulated by elemental ratios in litter while the home field advantage (HFA) hypothesis predicts that deco...

Pollen-vegetation richness and diversity relationships in the tropics (2017)
Journal Article

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..

Is pollen size a robust proxy for moisture availability? (2017)
Journal Article

The development of well-constrained palaeo-proxies that enable the reconstruction of past climate change is becoming an ever more important field of scientific enquiry within the palaeobotanical community, with the potential to deliver broader impact...

Pollen and spores as biological recorders of past ultraviolet irradiance (2016)
Journal Article

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

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

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...

Plant responses to elevated CO 2 levels in soils: Distinct CO 2 and O 2 -depletion effects (2016)
Journal Article

To investigate potential environmental effects in the context of carbon dioxide (CO2) leakage from Carbon Capture and Storage (CCS) schemes, the University of Nottingham ASGARD (Artificial Soil Gassing And Response Detection) facility, was used to in...

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...

The impact of oxidation on spore and pollen chemistry (2015)
Journal Article

Sporomorphs (pollen and spores) have an outer wall composed of sporopollenin. Sporopollenin chemistry contains both a signature of ambient ultraviolet-B flux and taxonomic information, but it is currently unknown how sensitive this is to standard pal...

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...

Pollen and spores as a passive monitor of ultraviolet radiation (2014)
Journal Article

© 2014 Fraser, Lomax, Jardine, Gosling and Sephton. Sporopollenin is the primary component of the outer walls of pollen and spores. The chemical composition of sporopollenin is responsive to levels of ultraviolet (UV) radiation exposure, via a concom...
