Research interests
My research at the University of Bristol is focused on the development of two non-invasive survey tools for freshwater ecosystems, ecoacoustics and environmental DNA (eDNA).
Freshwater ecoacoustics
The field of freshwater ecoacoustics is a new and rapidly growing area of research in which the sounds in a pond, lake or river are recorded and analysed to answer ecological questions. Listening to the underwater sounds in freshwaters has huge potential to reveal novel insights into freshwater ecosystem function and condition. In addition, to showcase the staggering biodiversity of freshwater ecosystems and raise awareness of conservation efforts through scientific and artistic sound recordings.
Environmental DNA
I am also using eDNA to detect, and map the distributions of, native and invasive crayfish species in the UK. In partnership with the Norfolk Rivers Trust and the Environment Agency, I recently conducted a crayfish eDNA survey of 10 river catchments in Norfolk, UK. A greater understanding of the distribution of signal and white-clawed crayfish will inform local conservation efforts and help reduce freshwater biodiversity loss.
