Abstract
The ascidian Trididemnum solidum competes for space on Caribbean reefs and is capable of overgrowing live scleractinian corals From 2006 to 2009 we monitored over 30000 coral colonies and quantified competitive interactions with this ascidian at four reef sites along the Mexican Caribbean The total number of competitive interactions increased in time but the mean percentage of coral colonies involved in interactions remained lower than 1 in all reefs Bottom cover by T solidum was also low mean 05 in all reef sites in all sampling years We conclude that during the temporal scope of our study the overall potential effect of T solidum on the dynamics of Mexican Caribbean coral populations was minimalWe thank MA Maldonado L VázquezVera and J Andras for assistance in the field This manuscript was greatly improved by comments from P Blanchon This work was supported by the Coral Disease Working Group of the Global Environment Facility Coral Targeted Research program and by the Instituto de Ciencias del Mar y Limnología UNAM
