     View Summary

    We discussed the significance of "phylogenetic diversity (diversity of evolutionary history)" as an index for biodiversity conservation of tropical rain forest. Using a detailed molecular phylogeny estimated for 699 tree species in a Bornean rain forest, we found that maximum size and demographic traits, such as mortality and growth rates, were more similar among phylogenetically more closely related species, while habitat niche was various even among them. This suggests that niche habitat is an evolutionary labile trait and that divergence in habitat niche may enhance coexistence of closely related species, which have similar adult size and demographic traits. We also found that the relationship between species and phylogenetic diversity was not straightforward but rather complicated, which suggested that we need to consider both species and phylogenetic diversity simultaneously in biodiversity conservation of tropical rain forest.

  • Development and application of sex-linked DNA markers in a natural population of a dioecious tree

     View Summary

    Five sex-linked DNA markers were developed in Nageia nagi (Podocarpaceae), a dioecious tree, using genome-wide RAD sequence data. We got 250,000 DNA sequence leads (100 bp) per individual in average. Although no female-specific sequences were found from these leads, 5 male-specific sequences were obtained. For the 5 sequences, PCR primer pairs were designed to identify sex of non-reproductive individuals.
    For the assessment of sex ratio of non-reproductive seedlings, 148 seedlings from 4 sites in a natural population were analyzed on Mt. Mikasa, Nara Prefecture, Japan. The number of analyzed seedlings in a site raged from 32 to 45, and the proportion of males in a site varied from 0.465 to 0.600. No significant deviations of sex ratio from 1:1 were detected in any sites, and sex ratios were not significantly different among 4 sites. In the natural population of N. nagi, expected sex ratio at seedling stage was considered as 1:1 in any sites.

  • Estimating origin and expansion process of hybrid dandelions in Japan with genetic and ecological analysis

     View Summary

    We studied origin and expansion process of hybrid dandelions in Japan with genetic analysis and cultivation experiment. We found unique cpDNA types to Taraxacum japonicum or other diploid native dandelions, indicating a possibility to use cpDNA for estimating origin of hybrids. We found only few hybrids that had unique cpDNA to T. japnicum. Proportion of hybrids in apparent exotic dandelions were higher in eastern than western Japan. The cultivation experiment showed that hybrids growing in different vegetation differed in cpDNA and growth features. These results suggest that difference in native dandelions that produced hybrids may influence the frequency, establishment and expansion of hybrid dandelions in Japan.
