Desiccation tolerance of the introduced marine green alga Codium fragile ssp. Tomentosoides - clues for likely transport vectors
The invasive marine green macroalga Codium fragile ssp. tomentosoides is now considered to be an introduced marine pest along the northwest Atlantic and southern Australian coasts. International or domestic translocation of C. fragile ssp. tomentosoides is usually attributed to the fouling of ship h...
