Invasive Species Interaction Biosecurity Risks Ecological Collapse

Researchers have discovered that Western honey bees in Australia may forage on myrtle rust spores as a nutritious food source. This interaction could facilitate the spread of the invasive fungus via commercial beehive transport and create an ecological feedback loop as native plants are destroyed.

“New research published in NeoBiota has found that the Western honey bee—an introduced species to Australia—and the devastating, invasive plant fungus known as myrtle rust (Austropuccinia psidii) may have formed a mutually beneficial relationship known as "invasional mutualism."”
CORROBORATED
Multiple web search results from academic-style snippets and news-like summaries confirm that research indicates a potential mutualistic interaction (invasional mutualism) between Apis mellifera and Austropuccinia psidii.
