Profile

Biography

Richard is a broad-ranging Environmental Scientist interested in environmental change and environmental management.

His research combines modern experimental and observational studies with the palaeo-environmental record, focussing particularly on climate change and pollution. Much of his work concerns peatlands which are both the most important terrestrial carbon store by area and a valuable archive of past environmental change.

His palaeoecological research has focussed on the reconstruction of Holocene climate change from peats particularly using testate amoebae. Increasingly this research theme has also involved studies of the climate sensitivities of modern peatlands including a major climate change simulation experiment.

His interest in the impacts of pollution began with his PhD research on the environmental impacts of volcanic eruptions but has since expanded to encompass anthropogenic pollution.

He has worked on the impacts of nitrogen, sulphur and ozone pollution on plant and microbial communities and the ways by which these impacts can be monitored and managed.

He was appointed Lecturer in Environmental Geography in 2015 after a peripatetic academic career thus-far spanning twelve institutions in seven countries. 

Research

Overview

Richard's research interests can be divided amongst three overlapping themes.

Peatlands and climate

Peat develops due to an imbalance between production and decomposition. Decomposition is slow in the acidic, anoxic environment of a peatland and so organic remains slowly accumulate over time as peat. This slow and steady accretion of organic matter has a couple of interesting implications. Peat is about 50% carbon so global peatlands have accumulated a very large amount of carbon through the Holocene, around 4-600Gt. This carbon store may be imperilled by human activity, either directly through poor land management, or indirectly through factors such as air pollution and climate change. The characteristics of slow decomposition and continuous accretion of material also make peatlands an excellent medium for palaeoecology. We can analyse the preserved remains of the organisms which once grew on the surface of the bog and use changes in their abundance through a peat core to investigate how the peatland and its wider environment changed over time.

His interests in peatlands and climate change started from a palaeoecological perspective with the need to reconstruct past climate change in order to understand current climate variability and predict the future. His palaeoecological research has focussed on the reconstruction of Holocene climate change from peats in Europe and North America, and the uncertainties underlying these reconstructions. Key to much of his work has been testate amoebae; a group of charismatic microorganisms which we know respond to climate change. Current research is investigating the long-term accumulation of carbon by peatlands and the links to climate change.

More recently his interest in peatlands and climate has expanded into contemporary systems. Since 2010 with colleagues from Manchester Metropolitan and Edge Hill Universities he has worked on a field climate manipulation experiment on a bog in Wales. Over this time they have observed considerable change in plant and microbial communities and changes to carbon cycling. 

Applied palaeoecology

Richard's background has spanned ‘neo’-ecology and palaeoecology so he is particularly interested in both how ecological studies can inform palaeoecological reconstruction and how we can use palaeoecological data to address questions about contemporary ecosystems. One aspect of this is the use of palaeoecological techniques to address issues in environmental management. For instance, in current research they are using tephrochronology and carbon accumulation reconstructions to address the impact of conifer afforestation on peatlands.

Air pollution impacts

Another area of interest is the ecological impact of air pollutants. Richard has worked on the impacts of ozone, sulphur and particularly nitrogen deposition on plant and microbial communities. His particular contributions have been in using spatial gradients to identify air pollution impacts in real-world landscapes. He has been involved in three consultancy projects for UK national conservation agencies on these topics. He also have interests in volcanogenic pollution including his PhD research on volcanic impacts on peatlands.
