Article Synopsis
- Oceanic islands are valuable for studying plant ecology and evolution, particularly through cases like Callicarpa glabra, Callicarpa parvifolia, and Callicarpa subpubescens, which are native to the Ogasawara Islands.
- These species exemplify evolutionary changes such as adaptive radiation and dioecious sex expression, making them ideal candidates for understanding genetic relationships and colonization processes.
- Phylogenomic analysis revealed that these species share a common ancestor with East Asian plants, having diverged about three million years ago, likely due to long-distance dispersal from East Asia followed by speciation on the islands.
Interspecific hybridization between two species of Japanese toads, (Bt) and (Bjf), was not thought to have occurred due to the differences in their spawning habitats, although their hybridization was reported by previous research in a limited area. Such hybridization could have pivotal effects, such as genetic admixture, on Bt, which has a limited distribution and habitat. In this study, to clarify the details of hybridization, a total of 192 individuals were collected from multiple parapatric regions and an only Bjf allopatric region and analyzed based on morphology, mtDNA sequences, and nuclear DNA microsatellite loci.
