Abstract

We examined the patterns of distribution and abundance, and reproductive traits (presence of game-tophytes and size at time of reproduction) in the invasive Codium fragile ssp. fragile and the native C tomentosum and C vermilara on intertidal habitats of NW Spain at two dates. All three species coexist in the locations and habitats studied, although abundances were low. We found a greater proportion of C fragile ssp. fragile towards the east of the Cantabrian coast and on upper levels on the shore, where conditions are more stressful. The proportion of thalli bearing gametangia in C fragile ssp. fragile was greater than in the native species in all habitats. The presence of gametangia was size-dependent for all species, with the invasive species maturing at a smaller size, which combined with the previous features, might confer competitive advantages to this species over the native species. We also demonstrated that molecular analyses are necessary for the correct identification of C. fragile subspecies. (C) 2014 Elsevier Ltd. All rights reserved.
