Research Abstract

The primary object of this research was to reconstruct regeneration processes of secondary forest by means of genetic markers and mathematical models. We have also developed new statistical models and applied them to long-term forest monitoring data.
We analyzed isozyme and microsatellite markers in two secondary beech-dominant stands in Tohoku district and applied genetic inhomogeneous Poisson processes. We obtained the maximum likelihood estimates about forest regeneration parameters such as seed dispersal, pollen flow and individual female reproductive success, which gave implications about forest regeneration mechanisms in the past.
In the other beech-dominant stand in Tohoku district, we checked old forestry records and tried to correspond them to current stands and the resulting stand structures. Then we analyzed microsatellite markers and estimated the contribution of advanced regeneration prior to the harvesting.
On the other hand, in the old-growth forest in Hokkaido, we analyzed … More 10-years forest community dynamics, in particular spatial pattern changes and interactions between conifers and broad-leaved species. In addition, we conducted dendrochronological analysis as well as microsatellites for Abies sachalinensis and examined its long-term dynamics in the forest community dynamics. We have also investigated 7-years sapling bank dynamics of Abies mariesii in the central mountainous regions in Japan.
In the southern part of Japan, we constructed seedling survival models of Castanopsis sieboldii in Okinawa Island, in which Bayesian nonparametric smoothing technique and model selection by AIC played a central role. In another southern island, Tsushima, there is an old-growth forest where long-term forest monitoring has been conducted for 12 years. Using this dataset and applying the nonparametric Bayesian smoothing binary regression, we derived size-dependent mortality patterns for 11 evergreen species.
Finally, the models used in the secondary beech-dominant stands originated from the gene flow models for investigating Fraxinus mandshurica populations in Hokkaido. Less
