Tracking the invasive history of the green alga Codium fragile ssp. tomentosoides
Abstract The spread of nonindigenous species into new habitats is having a drastic effect on natural ecosystems and represents an increasing threat to global biodiversity. In the marine environment, where data on the movement of invasive species is scarce, the spread of alien seaweeds represents a p...
