| geographic occurrence of intermediate type between castanopsis sieboldii and c. cuspidata (fagaceae) based on the structure of leaf epidermis. | the number of layers of epidermis in the leaves is used as a criterion to distinguish between castanopsis sieboldii (two layers) and c. cuspidata (one layer). an intermediate type, which has one and two layers within a single leaf, is frequently seen in the field. the origin of the intermediate type has been supposed to be a hybrid between c. sieboldii and c. cuspidata. if the intermediate type is produced by hybridization, we expect that the f(1) seedlings of the intermediate type should occur ... | 2003 | 14586806 |
| microsatellite variation and differentiation among local populations of castanopsis species in japan. | microsatellite variations in castanopsis species in japan were examined to clarify the genetic relationships among 25 local populations according to the difference in the number of layers of adaxial epidermis in the leaves. six microsatellite loci were assayed for 629 seedlings from the populations, and these seedlings were classified into five types according to the state of the leaf epidermis. remarkable differences in the allele frequency of the six microsatellite loci were observed among the ... | 2006 | 16284707 |
| [eco-hydrological characteristics of a subtropical evergreen broadleaved forest in japan]. | a three years (1998-2000) observation on the eco-hydrological characteristics of castanopsis sieboldii and schima wallichii dominated subtropical evergreen broadleaved forest on the okinawa island of japan showed that during the observation period, the mean annual precipitation was 3325 mm, and 42.3% of it was directly or indirectly contributed by typhoon rainfall, implying that typhoon played a very important role in the hydrology of the forest. through-fall and stem-flow contributed to 53.9% a ... | 2006 | 17147158 |
| temporal distance decay of similarity of ectomycorrhizal fungal community composition in a subtropical evergreen forest in japan. | community compositions of ectomycorrhizal (ecm) fungi are known to show spatial distance decay of similarity, which arises from both deterministic niche-based processes and stochastic spatial-based processes (e.g. dispersal limitation). recent studies have highlighted the importance of incorporating the spatial-based processes in the study of community ecology of ecm fungi. however, few studies have investigated the temporal distance decay of similarity of ecm fungal communities. more specifical ... | 2016 | 26989126 |
| patterns of pollen flow in a dense population of the insect-pollinated canopy tree species castanopsis sieboldii. | insect pollinations of tree species with high-density populations have rarely been studied. since the density of adults can affect effective pollen dispersal, short-distance pollination, even by insects, may frequently occur in high-density populations. to test this prediction, we investigated pollination patterns in a high-density population of the insect-pollinated canopy tree species castanopsis sieboldii by paternity analysis using genotypes at 8 microsatellite loci of 145 adult trees and 43 ... | 2012 | 22573791 |
