Journal Article
Sumner-Kalkun, J., Sjölund, M., Arnsdorf, Y., Carnegie, M., Highet, F., Ouvrard, D., …Kenyon, D. (2020). A diagnostic real-time PCR assay for the rapid identification of the tomato-potato psyllid, Bactericera cockerelli (Šulc, 1909) and development of a psyllid barcoding database. PloS one, 15(3), Article e0230741. https://doi.org/10.1371/journal.pone.0230741

The accurate and rapid identification of insect pests is an important step in the prevention and control of outbreaks in areas that are otherwise pest free. The potato-tomato psyllid Bactericera cockerelli (Šulc, 1909) is the main vector of ‘Candidat...

Are insects declining and at what rate? An analysis of standardised, systematic catches of aphid and moth abundances across Great Britain (2020)
Journal Article
Bell, J., Blumgart, D., & Shortall, C. (2020). Are insects declining and at what rate? An analysis of standardised, systematic catches of aphid and moth abundances across Great Britain. Insect Conservation and Diversity, 13(2), 115-126. https://doi.org/10.1111/icad.12412

Although we have known anecdotally that insects have been declining in Great Britain for more than 100 years, insect declines have only been statistically estimated over the last 20 years. Estimation of the rate of those declines is still hotly debat... Read More about Are insects declining and at what rate?

Population genetic structure and predominance of cyclical parthenogenesis in the bird cherry–oat aphid Rhopalosiphum padi in England (2020)
Journal Article
Morales-Hojas, R., Gonzalez-Uriarte, A., Alvira Iraizoz, F., Jenkins, T., Alderson, L., Kruger, T., …Bell, J. R. (2020). Population genetic structure and predominance of cyclical parthenogenesis in the bird cherry–oat aphid Rhopalosiphum padi in England. Evolutionary Applications, 13(5), 1009-1025. https://doi.org/10.1111/eva.12917

Genetic diversity is the determinant for pest species’ success and vector competence. Understanding the ecological and evolutionary processes that determine the genetic diversity is fundamental to help identify the spatial scale at which pest populat...

Moth biomass has fluctuated over 50 years in Britain but lacks a clear trend (2019)
Journal Article
Macgregor, C. J., Williams, J. H., Bell, J. R., & Thomas, C. D. (2019). Moth biomass has fluctuated over 50 years in Britain but lacks a clear trend. Nature Ecology & Evolution, 3, 1645–1649. https://doi.org/10.1038/s41559-019-1028-6

Steep insect biomass declines ('insectageddon') have been widely reported, despite a lack of continuously collected biomass data from replicated long-term monitoring sites. Such severe declines are not supported by the world’s longest running insect... Read More about Moth biomass has fluctuated over 50 years in Britain but lacks a clear trend.

Climate-induced phenology shifts linked to range expansions in species with multiple reproductive cycles per year (2019)
Journal Article
Macgregor, C. J., Thomas, C. D., Roy, D. B., Beaumont, M. A., Bell, J. R., Brereton, T., …Hill, J. K. (2019). Climate-induced phenology shifts linked to range expansions in species with multiple reproductive cycles per year. Nature Communications, 10, Article 4455. https://doi.org/10.1038/s41467-019-12479-w

Advances in phenology (the annual timing of species’ life-cycles) in response to climate change are generally viewed as bioindicators of climate change, but have not been considered as predictors of range expansions. Here, we show that phenology adva... Read More about Climate-induced phenology shifts linked to range expansions in species with multiple reproductive cycles per year.

Spatial and habitat variation in aphid, butterfly, moth and bird phenologies over the last half century (2019)
Journal Article

Spatial and habitat variation in aphid, butterfly, moth and bird phenologies over the last half century. Global Change Biology, 25(6), 1982-1994. https://doi.org/10.1111/gcb.14592

Global warming has advanced the timing of biological events, potentially leading to disruption across trophic levels. The potential importance of phenological change as a driver of population trends has been suggested. To fully understand the possibl...

Reliable assessment of extinction risk is a key factor in the preparation of Red Lists and in prioritizing biodiversity conservation. Temporal population trends can provide important evidence for such assessments, but imperfect sampling (observation... Read More about Insect population trends and the IUCN Red List process.
