Dynamic selection of environmental variables to improve the prediction of aphid phenology: A machine learning approach (2018)
Journal Article
Holloway, P., Kudenko, D., & Bell, J. R. (2018). Dynamic selection of environmental variables to improve the prediction of aphid phenology: A machine learning approach. Ecological Indicators, 88, 512-521. https://doi.org/10.1016/j.ecolind.2017.10.032

Insect pests now pose a greater threat to crop production given the recent emergence of insecticide resistance, the removal of effective compounds from the market (e.g. neonicotinoids) and the changing climate that promotes successful overwintering a...

The sensitivity of breeding songbirds to changes in seasonal timing is linked to population change but cannot be directly attributed to the effects of trophic asynchrony on productivity (2017)
Journal Article
Franks, S. E., Pearce-Higgins, J. W., Atkinson, S., Bell, J. R., Botham, M. S., Brereton, T. M., Harrington, R., & Leech, D. I. (2018). The sensitivity of breeding songbirds to changes in seasonal timing is linked to population change but cannot be directly attributed to the effects of trophic asynchrony on productivity. Global Change Biology, 24(3), 957-971. https://doi.org/10.1111/gcb.13960

A consequence of climate change has been an advance in the timing of seasonal events. Differences in the rate of advance between trophic levels may result in predators becoming mismatched with prey availability, reducing fitness and potentially drivi...

Aphid population dynamics: from fields to landscapes. (2017)
Book Chapter
Bell, J., Pierre, J., & Dedryver, C. (2017). Aphid population dynamics: from fields to landscapes. In Aphids as crop pests (280-302). (2). Centre for Agriculture and Bioscience International (CABI). https://doi.org/10.1079/9781780647098.0280

Cereal aphid studies form the backbone of this chapter and will be discussed at length, but shall also occasionally discuss the dynamics of aphids that use other annual crops and trees as their host. The overall purpose is to outline the components o... Read More about Aphid population dynamics: from fields to landscapes..

A New Approach to Modelling the Relationship Between Annual Population Abundance Indices and Weather Data (2017)
Journal Article
Elston, D., Brewer, M., Martay, B., Johnston, A., Henrys, P., Bell, J., Harrington, R., Monteith, D., Brereton, T., Boughey, K., & Pearce-Higgins, J. (2017). A New Approach to Modelling the Relationship Between Annual Population Abundance Indices and Weather Data. Journal of Agricultural, Biological and Environmental Statistics, https://doi.org/10.1007/s13253-017-0287-4

Weather has often been associated with fluctuations in population sizes of species; however, it can be difficult to estimate the effects satisfactorily because population size is naturally measured by annual abundance indices whilst weather varies on...

Handbook of protocols for standardized measurement of terrestrial invertebrate functional traits (2016)
Journal Article
Moretti, M., Dias, A. T., de Bello, F., Altermatt, F., Chown, S. L., Azcárate, F. M., Bell, J. R., Fournier, B., Hedde, M., Hortal, J., Ibanez, S., Öckinger, E., Sousa, J. P., Ellers, J., & Berg, M. P. (2017). Handbook of protocols for standardized measurement of terrestrial invertebrate functional traits. Functional Ecology, 31(3), 558-567. https://doi.org/10.1111/1365-2435.12776

Trait-based approaches are increasingly being used to test mechanisms underlying species assemblages and biotic interactions across a wide range of organisms including terrestrial arthropods and to investigate consequences for ecosystem processes. Su... Read More about Handbook of protocols for standardized measurement of terrestrial invertebrate functional traits.

Impacts of climate change on national biodiversity population trends (2016)
Journal Article
Martay, B., Brewer, M., Elston, D., Bell, J., Harrington, R., Brereton, T., Barlow, K., Botham, M., & Pearce-Higgins, J. (2017). Impacts of climate change on national biodiversity population trends. Ecography, 40(10), 1139-1151. https://doi.org/10.1111/ecog.02411

Climate change has had well-documented impacts on the distribution and phenology of species across many taxa, but impacts on species’ abundance, which relates closely to extinction risk and ecosystem function, have not been assessed across taxa. In t... Read More about Impacts of climate change on national biodiversity population trends.
