© 2017 The Authors. Ecology and Evolution published by John Wiley & Sons Ltd. A fundamental consideration for the conservation of a species is the extent of its native range, that is, regions naturally colonized. However, both natural processes and... Read More

Environmental DNA metabarcoding of lake fish communities reflects long-term data from established survey methods (2016)
Journal Article
Hahn, C., Blackman, R. C., Hänfling, B., Lawson Handley, L., Li, J., Nichols, P., …Winfield, I. J. (2016). Environmental DNA metabarcoding of lake fish communities reflects long-term data from established survey methods. Molecular ecology, 25(13), (3101-3119). doi:10.1111/mec.13660. ISSN 0962-1083

Organisms continuously release DNA into their environments via shed cells, excreta, gametes and decaying material. Analysis of this ‘environmental DNA’ (eDNA) is revolutionizing biodiversity monitoring. eDNA outperforms many established survey method... Read More

How will the 'molecular revolution' contribute to biological recording? (2015)

© 2015 The Linnean Society of London. Soaring throughput, plummeting costs, and increased sensitivity for assaying degraded or low-concentration DNA are driving a revolution in the way that we monitor biodiversity. Arguably the biggest 'game-changer'... Read More

Cannibalism in invasive, native and biocontrol populations of the harlequin ladybird (2014)
Journal Article
Tayeh, A., Estoup, A., Lombaert, E., Guillemaud, T., Kirichenko, N., Lawson-Handley, L., …Facon, B. (2014). Cannibalism in invasive, native and biocontrol populations of the harlequin ladybird. BMC evolutionary biology, 14(1), doi:10.1186/1471-2148-14-15

Background Cannibalism is widespread in both vertebrates and invertebrates but its extent is variable between and within species. Cannibalism depends on population density and nutritional conditions, and could be beneficial during colonisation of new... Read More

The value of an egg: Resource reallocation in ladybirds (Coleoptera: Coccinellidae) infected with male-killing bacteria (2011)
Journal Article
Elnagdy, S., Majerus, M., & Lawson Handley, L. (2011). The value of an egg: Resource reallocation in ladybirds (Coleoptera: Coccinellidae) infected with male-killing bacteria. Journal of evolutionary biology, 24(10), (2164-2172). doi:10.1111/j.1420-9101.2011.02346.x. ISSN 1010-061X

Male‐killing bacteria are thought to persist in host populations by vertical transmission and conferring direct and/or indirect fitness benefits to their hosts. Here, we test the role of indirect fitness benefits accrued from resource reallocation in... Read More
