| cryptic species of didymobothrium rudolphii (cestoda: spathebothriidea) from the sand sole, solea lascaris, off the portuguese coast, with an analysis of their molecules, morphology, ultrastructure and phylogeny. | didymobothrium rudolphii (cestoda: spathebothriidea) was collected seasonally from the sand sole, solea lascaris, off the northern, central and southern areas of the portuguese coast. morphological and molecular analyses were conducted in order to examine the possible existence of cryptic species and to facilitate the circumscription of their morphological boundaries. data were compared between d. rudolphii specimens from each of the 3 geographical areas and 4 seasons, and principal components a ... | 2007 | 17326848 |
