A study by former C·I·B Hons student, Cally Jansen and C·I·B Core Team Member, Dr Sabrina Kumschick used acacias introduced to South Africa as a case study to compare expert assessments with evidence-based impact assessments.
Impact classification schemes for alien taxa are becoming more prominent as the threats posed by biological invasions increase. A recent study found that despite a high variety of uncertainties occurring in impact assessments, some of which cannot be eliminated easily, communicating their existence, cause and variety can lead to more useful and reliable outcomes of impact assessments.
Even though snails and slugs (gastropods) are some well-known agricultural pests, environmental systems are more vulnerable to alien gastropod impacts. A recent study by C·I·B Hons student, David Kesner and C·I·B Core Team Member, Dr Sabrina Kumschick, at Stellenbosch University on this topic was published in the journal Ecology and Evolution.
