Transcript of Caulerpa Taxifola
One strain was modified for use in the aquarium is the early 80's
Federal Noxious weed list
Accidentally released into Mediterranean sea in Monaco Asexual reproduction
fragments as small as 1cm can germinate into a new plant
extremely hardy temperature tolerance and can grow in low light
Dense and fast growth pattern
Produces toxic compounds inedible to native species Genetically flexible
Grows on a variety of surfaces on the sea bed
Can grow in nutrient poor areas Chokes out native species of seaweed
Toxicity of plant makes it inedible to local herbivores
Fish that have eaten C. Taxifolia are inedible to humans
Removal using chlorine tarps is costly and also damaging to the environment High tolerance to chemicals allows it to clean up the water in local ports and sewage outlets
Tends to grow in areas that arent already occupied by another seaweed
may in fact increase biodiversity in some areas Although eradicated in 2007 of the coast of San Diego, removal cost upwards 7 million and severely impacted local ecosystem
A large tarp was placed over the C. Taxifolia bed, and massive quantities of chlorine were poured underneath
Researchers have proposed introducing a species of slug to slowly chew away at the C. Taxifolia Katz: Restoration of Nature
Hardin: Tragedy of the Commons
