Phenological sensitivity to climate across taxa and trophic levels (2016)
Journal Article
Thackeray, S. J., Henrys, P. A., Hemming, D., Bell, J. R., Botham, M. S., Burthe, S., …Wanless, S. (2016). Phenological sensitivity to climate across taxa and trophic levels. Nature, 535, 241–245. https://doi.org/10.1038/nature18608

Differences in phenological responses to climate change among species can desynchronise ecological interactions and thereby threaten ecosystem function. To assess these threats, we must quantify the relative impact of climate change on species at dif... Read More about Phenological sensitivity to climate across taxa and trophic levels.

Quantifying interspecific variation in dispersal ability of noctuid moths using an advanced tethered flight technique (2015)
Journal Article
Jones, H. B., Lim, K. S., Bell, J. R., Hill, J. K., & Chapman, J. W. (2016). Quantifying interspecific variation in dispersal ability of noctuid moths using an advanced tethered flight technique. Ecology and Evolution, 6(1), 181-190. https://doi.org/10.1002/ece3.1861

Dispersal plays a crucial role in many aspects of species' life histories, yet is often difficult to measure directly. This is particularly true for many insects, especially nocturnal species (e.g. moths) that cannot be easily observed under natural...

Changes in large-scale climate alter spatial synchrony of aphid pests (2015)
Journal Article
Sheppard, L. W., Bell, J. R., Harrington, R., & Reuman, D. C. (2016). Changes in large-scale climate alter spatial synchrony of aphid pests. Nature Climate Change, 6, Article 610-613. https://doi.org/10.1038/NCLIMATE2881

Spatial synchrony, the tendency of distant populations to fluctuate similarly, is a major concern in ecology1,2,3,4,5,6,7,8. Except in special circumstances3,9, researchers historically had difficulty identifying drivers of synchrony in field systems...

Organic Farming: Biodiversity Impacts Can Depend on Dispersal Characteristics and Landscape Context (2015)
Journal Article
Feber, R. E., Johnson, P. J., Bell, J. R., Chamberlain, D. E., Firbank, L. G., Fuller, R. J., …Macdonald, D. W. (2015). Organic Farming: Biodiversity Impacts Can Depend on Dispersal Characteristics and Landscape Context. PloS one, 10(8), Article e0135921. https://doi.org/10.1371/journal.pone.0135921

Organic farming, a low intensity system, may offer benefits for a range of taxa, but what affects the extent of those benefits is imperfectly understood. We explored the effects of organic farming and landscape on the activity density and species den...

Large-scale migration synchrony between parasitoids and their host (2015)
Journal Article
PÉREZ-RODRÍGUEZ, J., SHORTALL, C. R., & BELL, J. R. (2015). Large-scale migration synchrony between parasitoids and their host. Ecological Entomology, 40(5), 654-659. https://doi.org/10.1111/een.12241

1. Parasitoids are a valuable group for conservation biological control. In their role as regulators of aphid pests, it is critical that their lifecycle is synchronised with their hosts in both space and time. This is because a synchronised parasitoi...

Long-term phenological trends, species accumulation rates, aphid traits and climate: five decades of change in migrating aphids (2014)
Journal Article
Bell, J. R., Alderson, L., Izera, D., Kruger, T., Parker, S., Pickup, J., …Harrington, R. (2015). Long-term phenological trends, species accumulation rates, aphid traits and climate: five decades of change in migrating aphids. Journal of Animal Ecology, 84(1), 21-34. https://doi.org/10.1111/1365-2656.12282

Aphids represent a significant challenge to food production. The Rothamsted Insect Survey (RIS) runs a network of 12·2-m suction-traps throughout the year to collect migrating aphids. In 2014, the RIS celebrated its 50th anniversary. This paper marks...

Predicting Insect Migration Density and Speed in the Daytime Convective Boundary Layer (2013)
Journal Article
Bell, J. R., Aralimarad, P., Lim, K., & Chapman, J. W. (2013). Predicting Insect Migration Density and Speed in the Daytime Convective Boundary Layer. PloS one, 8(1), Article e54202. https://doi.org/10.1371/journal.pone.0054202

Insect migration needs to be quantified if spatial and temporal patterns in populations are to be resolved. Yet so little ecology is understood above the flight boundary layer (i.e. >10 m) where in north-west Europe an estimated 3 billion insects km−...

Intraguild predation in winter wheat: prey choice by a common epigeal carabid consuming spiders (2012)
Journal Article
Davey, J. S., Vaughan, I. P., King, R. A., Bell, J. R., Bohan, D. A., Bruford, M. W., …Symondson, W. O. (2013). Intraguild predation in winter wheat: prey choice by a common epigeal carabid consuming spiders. Journal of Applied Ecology, 50(1), 271-279. https://doi.org/10.1111/1365-2664.12008

Predators can provide a valuable ecosystem service by suppressing crop pests. However, intraguild predation, where predators compete for the same prey resource whilst consuming each other, may destabilize population dynamics and increase the risk of...
