FTIR spectra from grass pollen: A quest for species-level resolution of Poaceae and Cerealia-type pollen grains (2023)
Journal Article

Palynological analysis based on spore and pollen morphology is well established in the field of palaeo-environmental reconstruction but is currently not fully exploited for understanding the history and development of cereal cultivation due to diffic...

Response to Comment on "Dying in the Sun: Direct evidence for elevated UV-B radiation at the end-Permian mass extinction" (2023)
Journal Article

Seddon and Zimmermann have raised questions about the evidence for increased UV-B flux across the end-Permian mass extinction (EPME) that was presented in our recent study, specifically regarding the measurement of UV-B-absorbing compound (UAC) level...

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

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...

Ecology and climate sensitivity of a groundwater-fed lake on subtropical North Stradbroke Island (Minjerribah), Queensland, Australia over the last 7,500 years (2021)
Journal Article

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...

Temporal changes in litterfall and potential nutrient return in cocoa agroforestry systems under organic and conventional management, Ghana (2021)
Journal Article

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.

Sporopollenin chemistry and its durability in the geological record: an integration of extant and fossil chemical data across the seed plants (2021)
Journal Article

© 2021 The Authors. Palaeontology published by John Wiley & Sons Ltd on behalf of The Palaeontological Association. Sporopollenin is a highly resistant biopolymer that forms the outer wall of pollen and spores (sporomorphs). Recent research into sp...

Decomposition and nutrient mineralisation of leaf litter in smallholder cocoa agroforests: a comparison of organic and conventional farms in Ghana (2020)
Journal Article

© 2020, The Author(s). Purpose: Although litter decomposition and nutrient release patterns have been studied in cocoa agroforestry systems in general, studies focusing on organic and conventional cocoa systems are lacking which is critical as organi...

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...

Evaluation of vegetation communities, water table, and peat composition as drivers of greenhouse gas emissions in lowland tropical peatlands (2019)
Journal Article

© 2019 Elsevier B.V. Tropical peatlands are globally important source of greenhouse gases to the atmosphere, but data on carbon fluxes from these ecosystems is limited due to the logistical challenges of measuring gas fluxes in these ecosystems. Prop... Read More about Evaluation of vegetation communities, water table, and peat composition as drivers of greenhouse gas emissions in lowland tropical peatlands.

Plant responses to simulated carbon capture and storage (CCS) CO2 pipeline leakage: the effect of soil type (2019)
Journal Article

Carbon capture and storage (CCS) has been proposed as a bridging technology to enable the transition to an energy system based on renewable sources. Many high CO2?emitting industries (such as the power industry) are distant from potential carbon stor...
