Intraspecific sterility barrier confirms that introduction of Sphaerotrichia divaricata (Phaeophyceae, Chordariales) into the Mediterranean was from Japan
Crossing studies revealed an intraspecifìc sterility barrier on the level of zygote formation between Japanese Sphaerotrichia divaricata and isolates of the same species from the Northeast Pacific and the North Atlantic. Because no consistent morphological differences exist between sporophytes from...

Japanese Sphaerotrichia and isolates from a recently detected population in the Étang de Thau, French Mediterranean coast, are interfertile.
