“…However, there is no ecological information about the species. Furthermore, the Bonin Islands are a typical example of the changing balance in Japan between bio-diversity and single-minded development, between the desire to conserve native species and the desire to satisfy human desires, and between the modesty and creativity of local peoples and the arrogance and insensitivity inherent in massive public works funding[ 7 ]. Therefore, it is urgent that guidelines for conducting ex situ conservation and promoting the propagation of individuals for the next generation are put in place.…”

BackgroundMorus boninensis, is an endemic plant of the Bonin (Ogasawara) Islands of Japan and is categorized as "critically endangered" in the Japanese red data book. However, little information is available about its ecological, evolutionary and genetic status, despite the urgent need for guidelines for the conservation of the species. Therefore, we adopted Moritz's MU concept, based on the species' current genetic structure, to define management units and to select mother tree candidates for seed orchards.ResultsNearly all individuals of the species were genotyped on the basis of seven microsatellite markers. Genetic diversity levels in putative natural populations were higher than in putative man-made populations with the exception of those on Otouto-jima Island. This is because a limited number of maternal trees are likely to have been used for seed collection to establish the man-made populations. A model-based clustering analysis clearly distinguished individuals into nine clusters, with a large difference in genetic composition between the population on Otouto-jima Island, the putative natural populations and the putative man-made populations. The Otouto-jima population appeared to be genetically differentiated from the others; a finding that was also supported by pairwise FST and RST analysis. Although multiple clusters were detected in the putative man-made populations, the pattern of genetic diversity was monotonous in comparison to the natural populations.ConclusionThe genotyping by microsatellite markers revealed strong genetic structures. Typically, artificial propagation of this species has ignored the genetic structure, relying only on seeds from Otouto-jima for replanting on other islands, because of a problem with inter-specific hybridization on Chichi-jima and Haha-jima Islands. However, this study demonstrates that we should be taking into consideration the genetic structure of the species when designing a propagation program for the conservation of this species.

“…Although there is no doubting the ecological importance of the Ogasawara Islands and recent efforts at conservation and restoration, mainly by the islanders themselves supported by academics and environmentalists in Tokyo proper (Guo & McCormack, 2001), UNESCO recognition to some extent conceals the islands' troubled ecological history and their encounter with modernity, globalization, and the logic of the Japanese construction state (See: Guo & McCormack, 2001;Tyner, 2015). Rather, this identity is being promoted in part to bring the islands' ecologies within and to extend those logics by repositioning them for ecotourism, community revitalisation, and the deepening of Japan's geostrategic-economic position in the north-western Pacific.…”

“…Rather, this identity is being promoted in part to bring the islands' ecologies within and to extend those logics by repositioning them for ecotourism, community revitalisation, and the deepening of Japan's geostrategic-economic position in the north-western Pacific. Since the UNESCO designation, for example, and in contradiction to many islanders' stated preference for seaplanes (Guo & McCormack, 2001), Tokyo Metropolitan Government has revived its long-shelved plan to build an airport in Chichijima just outside the World Heritage designated area, but which threatens the biosecurity of the UNESCO site and would require changes to the areas protected under Japan's Natural Parks Law (The Mainichi, 2018).…”

Rethinking Locality in Japan

View full text Add to dashboard Cite

Every locale is a realisation of its own deep history and geography. As humanity continues to push beyond the limits of nature's capacity to provide solutions to the outcomes of modernization, in 21st century Japan everything is rendered local and global, particular and universal. In this chapter I examine the geology, ecology, and climate of Japan within the context of present-day environmental breakdown. Taking examples mainly from Tokyo Prefecture as a global locale, I show how Asia, with Japan in the vanguard, has emerged as a leading participant in the Great Acceleration of the depletion of the Earth's environmental capacity. Although Japan and Tokyo are by no means the only culprit, the consequence is that the Earth is passing from the stable Holocene into the Anthropocene epoch, where instability and unpredictability are the new, less forgiving, normal. I end by concluding that the Anthropocene disruption will force us to decentre and decelerate our humanity, and acknowledge that we are all connected; that Earth is our locale.
