Using a non-invasive approach (eDNA) to assess connectivity in aquatic biodiversity linked to water quality

(with Prof. Cobus van Dyk)

Heather is using environmental DNA (eDNA) to document aquatic diversity in different types of ecosystems including water and sediment, and to link diversity and connectivity to the water quality. Heather is working in an urban environment (Delta Park, Johannesburg) as well as a natural system (the Telperion Nature Reserve) on the border between Gauteng and Mpumalanga.  Heather has successfully used DNA in the environment to document a range of vertebrates and invertebrates in urban environments as well as a number of problematic (invasive) species.
