It is important that lists of invasive and alien species be updated regularly, but sometimes it can be difficult to decide when a species should be removed
The discovery of a clump of broad-leaved paper-bark trees (Melaleuca quinquenervia) in 2009 by a field ranger lead to an exciting study on this global wetland invader.
An interesting study by C∙I∙B PhD student, Saachi Sadchatheeswaran, examined the different number of species (species richness) and invertebrates on the rocky shores of Marcus Island after the arrival of alien species that were also ecosystem engineers.
Understanding how changes in the climate have influenced the spread of species is important if we want to conserve our most vulnerable species. Part of the answer lies in our ability to make predictions on whether species will be able to track predicted changes in the climate.
In November 2015 the Centre for Invasion Biology (C·I·B) hosted an international workshop entitled “Evolutionary dynamics of tree invasions: drivers, dimensions, and implications for management”.
