Recombination within the Cepaea nemoralis supergene is confounded by incomplete penetrance and epistasis (2019)
Journal Article
Ramos Gonzalez, D., Aramendia, A. C., & Davison, A. (2019). Recombination within the Cepaea nemoralis supergene is confounded by incomplete penetrance and epistasis. Heredity, doi:10.1038/s41437-019-0190-6

Although the land snail Cepaea nemoralis is one of the most thoroughly investigated colour polymorphic species, there have been few recent studies on the inheritance of the shell traits. Previously, it has been shown that the shell polymorphism is co... Read More

Single-gene speciation: mating and gene flow between mirror-image snails (2017)
Journal Article
Richards, P. M., Morii, Y., Kimura, K., Hirano, T., Chiba, S., & Davison, A. (2017). Single-gene speciation: mating and gene flow between mirror-image snails. Evolution Letters, 1(6), doi:10.1002/evl3.31. ISSN 2056-3744

Variation in the shell coiling, or chirality, of land snails provides an opportunity to investigate the potential for “single-gene” speciation, because mating between individuals of opposite chirality is believed not possible if the snails mate in a... Read More

A pilot study to survey the carnivore community in the hyper-arid environment of South Sinai Mountains (2017)
Journal Article
Gecchele, L. V., Bremner-Harrison, S., Gilbert, F., Soultan, A. E., Davison, A., & Durrant, K. L. (2017). A pilot study to survey the carnivore community in the hyper-arid environment of South Sinai Mountains. Journal of Arid Environments, 141, doi:10.1016/j.jaridenv.2017.01.009. ISSN 0140-1963

Carnivores are one of the taxa most affected by habitat fragmentation and human persecution; as a result, most carnivore species are declining; for this reason monitoring changes in carnivore population is paramount to plan effective conservation pro... Read More

Evidence of introgressive hybridization between the morphologically divergent land snails Ainohelix and Ezohelix (2015)
Journal Article
Morii, Y., Yokoyama, J., Kawata, M., Davison, A., & Satoshi, C. (2015). Evidence of introgressive hybridization between the morphologically divergent land snails Ainohelix and Ezohelix. Biological Journal of the Linnean Society, 115(1), doi:10.1111/bij.12466. ISSN 0024-4066

Hybridization between different taxa is likely to take place when adaptive morphological differences evolve more rapidly than reproductive isolation. When studying the phylogenetic relationship between two land snails of different nominal genera, Ain... Read More

A conserved set of maternal genes? Insights from a molluscan transcriptome (2014)
Journal Article
Liu, M. M., Davey, J. W., Jackson, D. J., Blaxter, M. L., & Davison, A. (2014). A conserved set of maternal genes? Insights from a molluscan transcriptome. International Journal of Developmental Biology, 58, doi:10.1387/ijdb.140121ad. ISSN 0214-6282

The early animal embryo is entirely reliant on maternal gene products for a ‘jump-start’ that transforms a transcriptionally inactive embryo into a fully functioning zygote. Despite extensive work on model species, it has not been possible to perform... Read More

Fine mapping of the pond snail left-right asymmetry (chirality) locus using RAD-Seq and fibre-FISH (2013)
Journal Article
Liu, M. M., Davey, J., Banerjee, R., Han, J., Yang, F., Aboobaker, A., …Davison, A. (2013). Fine mapping of the pond snail left-right asymmetry (chirality) locus using RAD-Seq and fibre-FISH. PLoS ONE, 8(8), doi:10.1371/journal.pone.0071067. ISSN 1932-6203

The left-right asymmetry of snails, including the direction of shell coiling, is determined by the delayed effect of a maternal gene on the chiral twist that takes place during early embryonic cell divisions. Yet, despite being a well-established cla... Read More

Irish Cepaea nemoralis land snails have a cryptic Franco-Iberian origin that is most easily explained by the movements of mesolithic humans (2013)
Journal Article
Grindon, A. J., & Davison, A. (2013). Irish Cepaea nemoralis land snails have a cryptic Franco-Iberian origin that is most easily explained by the movements of mesolithic humans. PLoS ONE, 8(6), doi:10.1371/journal.pone.0065792. ISSN 1932-6203

The origins of flora and fauna that are only found in Ireland and Iberia, but which are absent from intervening countries, is one of the enduring questions of biogeography. As Southern French, Iberian and Irish populations of the land snail Cepaea ne... Read More

Formin is associated with left-right asymmetry in the pond snail and the frog
Journal Article
Davison, A., McDowell, G. S., Holden, J. M., Johnson, H. F., Koutsovoulos, G. D., Liu, M. M., …Blaxter, M. L. (2016). Formin is associated with left-right asymmetry in the pond snail and the frog. Current Biology, doi:10.1016/j.cub.2015.12.071. ISSN 0960-9822

While components of the pathway that establishes left-right asymmetry have been identified in diverse animals, from vertebrates to flies, it is striking that the genes involved in the first symmetry-breaking step remain wholly unknown in the most obv... Read More
