| Abstract | Two major modes of speciation, i.e., cladogenesis and anagenesis, have often been used to explain the generation of distinct plant diversity on oceanic islands. Anagenetic speciation is of particular interest to plant endemics on Ulleung Island, Korea because, of nearly 40 endemics, approximately 88% or even all endemic species are thought to be anagenetically derived. Despite its important role in Ulleung Island, the full scope of the anagenetic speciation and the genetic consequences of this speciation mode have been limited to a very few families (i.e., Apiaceae, Sapindaceae, and Ranunculaceae). Based on extensive sampling (a total of 322 individuals) and trnL-F cpDNA noncoding sequences, we conducted phylogenetic and haplotype network analyses for the species pair of Rubus crataegifolius (continental progenitor)-R. takesimensis (insular derivative). Rubus takesimensis on Ulleung Island is not a monophyletic group, suggesting at least two independent introductions from geographically and genetically divergent source populations. No significant reduction in cpDNA haplotype diversity and genetic differentiation in R. takesimensis are consistent with expectations from the anagenetically derived species. A further study based on comprehensive sampling and more variable molecular markers will shed light into the genetic consequences of anagenetic speciation in Rubus on Ulleung Island. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
