Increasing globalisation has led to greater movement of new species around the world, and native species killed or stressed by global change will all too often be replaced by these weeds and feral animals.
That is why the theme for this year’s United Nations’ International Day for Biological Diversity relates to the insidious effect of invasive alien species on global biodiversity.
The International Convention on Biological Diversity is very clear on the IAS issue, labelling it as “one of the greatest threats to biodiversity, and to the ecological and economic well-being of society and the planet.”
CSIRO Biodiversity Research Director, Dr Mark Lonsdale, is acutely aware of the threat and in this podcast explains just how serious invasive alien species are to native ecosystems.
