How to define alien species?
A conceptual map of the proposed scheme for assessing the biogeographic status of taxa occurring in a regional species pool, showing the four assessment criteria, the levels of uncertainty in assessment, and the resulting assessment outcomes.

How to define alien species?

The human transport of species into new regions where they often become permanent additions to the fauna and flora has become a defining feature of our epoch, the Anthropocene.

Genetic diversity through space and time: Insights from the invasive smallmouth bass

Genetic diversity has long been considered a cornerstone of biological invasions. It is generally assumed that populations of an invasive alien species will have lower genetic diversity in the new invaded area when compared to populations in the native range.

Port Jackson impacts the restoration of Protea repens long after its removal

The growth of our native Sugarbush (Protea repens) is not negatively affected by the legacy of altered soil chemistry after the clearing of invasive Port Jackson (Acacia saligna).
