Predator versus practice: exploring predation and land management as drivers of small antelope occurrence

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.

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.
