| Abstract | As a result of ecological and historical factors, plant species occurring in mountainous regions often exhibit complex phylogeographical structure. The aim of this review is to identify the main phylogeographic patterns of plant species in the Japanese Archipelago, based on 63 previous studies; in particular, the intention is to examine the effects of mountains on these patterns. We classified species into three groups based on their distribution along altitudinal gradients: alpine and sub-alpine; montane; and lowland plants. Identified patterns were diverse, but we found particular ecological/historical constraints influencing the distribution of intra-population variation and contributing to clear genetic differentiation in alpine and sub-alpine and montane species. Many alpine and sub-alpine species harbored greater variation in the highlands of central Japan, and this was the case for dominant montane species in central and western Japan. These areas are considered to have acted as refugia during the last glacial maximum. Some other highland species even survived in small refugia in northern Japan. Genetic differentiation was regularly found between either side of 38°N latitude, between the Japan Sea and the Pacific Ocean sides of the country and on either side of the Itoiga-Shizuoka Tectonic Line. Unexpectedly, strong structure has rarely been found in lowland species. Based on the observed patterns, we discuss possible reasons for the discrepancies among phylogeographical structures of different species within the same groups. In addition, the phylogeographical patterns detected are compared with floristic structures described in classical biogeographical terms. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
