| Research Abstract |
(1) Genealogies of sika deer and sika deer lice were estimated using partial sequence of mitochondrial COI gene. Three lineages were identified for sika deer(Continental, Northern and Southern clades) whereas two lineages were identified for deer lice(Continent+southern Kyushu and others);(2) analyses of topological congruence revealed that there is no significant pattern of codivergence between deer and lice. The present analyses only used the maternally inherited gene marker so that male-deer mediated lice dispersal is considered to be the main source of the incongruence ;(3) long distance dispersal of lice apart from their host is quite unlikely. In such case, louse population genetic tree can be good indicators of hidden population structure in their host ;(4) using morphometric analyses, microevolutionary changes in deer lice morphology is shown to accumulate along phylogenetic lines. The neutral characters appeared to comprise a larger fraction of the variation compared to those expected to be more functionally significant. This suggests that random drift of more neutral characters plays a major role in the microevolution of morphology of deer lice
