Identifying agricultural crop pests quickly and reliably is critical to track their spread and to apply suitable control measures where needed. However, the identification of insect pests is often hampered by the lack of taxonomic expertise, especially in complex and poorly known tropical groups. DNA barcoding is often used as a supporting tool to identify species in the context of invertebrate pest management but relies on comprehensive and well-curated molecular databases.
The fires that started on 18 April 2021 on the slopes of Table Mountain in South Africa destroyed several buildings on the campus of the University of Cape Town. These included the Jagger Library, as well as the restaurant at Rhodes Memorial, the historic Mostert’s Mill, and several residential houses.

These are the results of a study by an international team of researchers led by Dr Hanno Seebens of the Senckenberg Biodiversity and Climate Research Center in Germany.
