Global biome patterns of the Middle and Late Pleistocene (2023)
Journal Article
Huntley, B., Allen, J. R., Forrest, M., Hickler, T., Ohlemüller, R., Singarayer, J. S., & Valdes, P. J. (2023). Global biome patterns of the Middle and Late Pleistocene. Journal of Biogeography, https://doi.org/10.1111/jbi.14619

Our primary aim was to assess the hypothesis that distinctive features of the patterns of vegetation change during successive Quaternary glacial–interglacial cycles reflect climatic differences arising from forcing differences. We addressed this hypo... Read More about Global biome patterns of the Middle and Late Pleistocene.

Holocene expansion of the Caledonian pinewoods: spatial and temporal patterns at regional and landscape scales (2021)
Journal Article
Huntley, B., & Allen, J. R. (2021). Holocene expansion of the Caledonian pinewoods: spatial and temporal patterns at regional and landscape scales. Plant Ecology and Diversity, 14(1-2), 23-46. https://doi.org/10.1080/17550874.2021.1984601

Background To facilitate climatic change adaptation, landscape and conservation managers require understanding of spatio-temporal patterns of expansion of potential dominant species. Studying past expansions of canopy-dominant trees can contribute su... Read More about Holocene expansion of the Caledonian pinewoods: spatial and temporal patterns at regional and landscape scales.

Projected climatic changes lead to biome changes in areas of previously constant biome (2021)
Journal Article
Huntley, B., Allen, J. R., Forrest, M., Hickler, T., Ohlemüller, R., Singarayer, J. S., …Williams, J. (2021). Projected climatic changes lead to biome changes in areas of previously constant biome. Journal of Biogeography, 48(10), 2418-2428. https://doi.org/10.1111/jbi.14213

Aim Recent studies in southern Africa identified past biome stability as an important predictor of biodiversity. We aimed to assess the extent to which past biome stability predicts present global biodiversity patterns, and the extent to which projec...

Using indices of species’ potential range to inform conservation status (2021)
Journal Article
Mason, T. H., Stephens, P. A., Gilbert, G., Green, R. E., Wilson, J. D., Jennings, K., …Willis, S. G. (2021). Using indices of species’ potential range to inform conservation status. Ecological Indicators, 123, https://doi.org/10.1016/j.ecolind.2021.107343

Assessments of conservation status are typically based on short-term extinction risk, but the value of indicators that compare the current state of species (e.g., abundance or distribution) to potential baselines is increasingly recognised. The use o... Read More about Using indices of species’ potential range to inform conservation status.

Global vegetation patterns of the past 140,000 years (2020)

Aim: Insight into global biome responses to climatic and other environmental changes is essential to address key questions about past and future impacts of such changes. By simulating global biome patterns 140 ka to present, we aimed to address impor... Read More about Global vegetation patterns of the past 140,000 years.

Diatom response to mid-Holocene climate in three small Arctic lakes in northernmost Finnmark (2015)
Journal Article
Roberts, S., Jones, V., Allen, J., & Huntley, B. (2015). Diatom response to mid-Holocene climate in three small Arctic lakes in northernmost Finnmark. Holocene, 25(6), 911-920. https://doi.org/10.1177/0959683615572853

Palaeoclimatic reconstructions from lake sediment biological records can be challenging, due to variation in non-climatic factors, which alter ecosystem responses. To consider this, it is important to replicate a study regionally, so as to gain infor...

Bayesian inference for palaeoclimate with time uncertainty and stochastic volatility (2015)
Journal Article
Parnell, A., Sweeney, J., Doan, T., Salter-Townshend, M., Allen, J., Huntley, B., & Haslett, J. (2015). Bayesian inference for palaeoclimate with time uncertainty and stochastic volatility. Journal of the Royal Statistical Society: Series C, 64(1), 115-138. https://doi.org/10.1111/rssc.12065

We propose and fit a Bayesian model to infer palaeoclimate over several thousand years. The data that we use arise as ancient pollen counts taken from sediment cores together with radiocarbon dates which provide (uncertain) ages. When combined with a...
