Riparian water availability affects potential nitrogen pollution by Black wattle

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.

Impacts of invasive crayfish on ecosystems

The management of invasive species is made more complex when more than one invasive species is present in a given ecosystem at the same time. Several invasive species may have a greater effect than one species does alone and there can be synergistic effects that result in a cascade of impacts and a large change in the way the ecosystem functions.
