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.
An intensive biodiversity assessment in the Kruger National Park, South Africa, recorded 20 naturalised alien plant species, of which only four had previously been recognized as invasive, and one species represented a new introduction for the park.
The way that we manage land influences species occurrence and interactions. However, in their recent study investigating species co-occurrence along the west coast of South Africa, Debbi Winterton, Nicola van Wilgen and Jan Venter discovered that intensive management of small areas also makes it difficult to detect ecological drivers.
Normally, frogs eat small invertebrates that easily fit into their mouths, but studies of stomach contents have shown that they sometimes eat eggs, tadpoles and even adults of other frogs. What are the conditions under which frogs eat frogs?
