Young species of cupuladriid bryozoans occupied new Caribbean habitats faster than old species

Abstract The breadth of habitat occupied by a species, and the rate at which a species can expand into new habitats has important ecological and evolutionary consequences. Here we explore when extant species of free-living cupuladriid bryozoans expanded into new benthic Caribbean habitats that emerg...
