I am interested in how we can use DNA sequences to understand biodiversity – how do we recognise species, and how are species related at taxonomic, ecological and geographic levels? My passion for biodiversity research has led me from the world’s largest natural history collection - Natural History Museum, London, where I completed my MSc, to the Biodiversity Institute of Ontario - global centre for the international Barcode of Life, as a PhD student, and to the hyper-diverse tropics of Southeast Asia. The tropics will be the first regions to experience historically unprecedented climates and this will happen within the next decade. Consequently my recent research has focussed on understanding the effects of urbanisation and climate change on tropical and subtropical biodiversity - encompassing both species richness and ecological integrity across a diversity of taxonomic groups.

Identity of the ailanthus webworm moth (Lepidoptera, Yponomeutidae), a complex of two species: evidence from DNA barcoding, morphology and ecology

During extensive ongoing campaigns to inventory moths of North America and Area de Conservacion Guanacaste (ACG), northwestern Costa Rica, we discovered that morphologically similar yponomeutid moths were assigned two different names, Atteva ergatica Walsingham in Costa Rica and A. punctella (Stoll) in North America, but had identical DNA barcodes. Combining DNA barcoding, morphology and food plant records also revealed a complex of two sympatric species that are diagnosable by their DNA barcodes and their facies in Costa Rica. However, neither of the names could be correctly applied to either species, as A. ergatica is a junior synonym and A. punctella a junior homonym. By linking our specimens to type material through morphology and DNA barcoding, we determined that the ACG dry forest species, distributed from Costa Rica to southern Quebec and Ontario, should be called A. aurea, whereas the similar and marginally sympatric ACG rain forest species found in Central America should be called A. pustulella. Neotypes are designated for Phalaena Tinea punctella Stoll, 1781 and Deiopeia aurea Fitch, 1857. Atteva floridana has identical barcodes to A. aurea and provisionally maintained as a synonym.
