The Reef Rescue work on blooms of Lyngbya, also a filamentous algae,
showed that blooms exploded at critical levels of certain nutrients from
specific sewer outfalls, then vanished when nutrients dropped only
slightly below those critical levels. It's quite a sight to see miles of
clear reef one week, a blanket of red cotton candy the next, and clear
(but heavily damaged) reef two weeks later. See
http://www.reef-rescue.org/PDFreports.shtml
These findings were used to close down one ocean outfall and get
legislation passed that will eventually close down the remaining five
outfalls in SE Florida.
There's a common Codium sp. that also explodes when temperatures hit
81-82 degrees and disappears quickly when the temp falls below.
There's a name for populations that come and go with a "trigger", but
I've forgotten it.
