[Coral-List] The brown alga Colpomenia sinuosa origin

[Iain Macdonald]

I am trying to establish the origin distribution of Colpomenia sinuosa as from my research it appears it was originally from the Pacific with a now global distribution. It appears to have a long (>100 year) history of being an invasive species (articles in Nature from the turn of the centuary!). Does anybody have more exact detials / references to its origin distribution / location?
 
I am interested in the spread into the Indian Ocean (especially north-west) and how it interacts with hard bottoms and coral communities as i have a feeling this could be a limiting factor in some areas coral community recovery that by its episodic blooming nature is often overlooked or not observed.
 
Thanks,
