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 leaf nitrogen dynamics of invading Black wattle (Acacia mearnsii) under conditions of varying water availability in fynbos riparian zones have not yet been examined. C·I·B student Casparus Crous (South African Environmental Observation Network), C·I·B Core Member Karen Esler and colleagues had a closer look at the nitrogen dynamics across fynbos riparian zones in the south-western Cape.
