GenotypeData100304.txt

This data is simple tab delimited text and its line break style is UNIX. It contains 9 microsatellite genotypes of 142 maternal trees and 1216 their seeds. In column headings, pop, family, fruit indicates population code, family and fruit ID, respectively. Fruit ID, whose value is 0, indicates that the individual is the maternal tree of seeds that has the same family ID of it. Lia and Lib indicates first and second alleles of the loci, respectively. Li_oc and Lall_oc indicates the outcrossing status of ith locus and over all loci. For example, if the value of L1_oc is 0 or 1, the status of first locus is selfed or outcrossed, respectively. NA indicates no data

Species habitat associations in an old-growth beech forest community organised by landslide disturbances

<p>In order to understand the processes that govern tree species’ spatial associations with habitats in landslide-affected forest communities, we investigated the habitat associations of six major tree species in an old-growth beech forest community located on a steep flank slope where landslides had occurred. All stems ≥ 5cm in diameter at breast height were mapped on a 1.14 ha polygonal plot and the topographic conditions (slope inclination and convexity), canopy state, and forest floor vegetation (i.e. dwarf bamboo and fern cover) were assessed. Most stems of <i>Fagus crenata</i> and <i>Acer japonicum</i> as well as many stems of <i>Magnolia obovata</i> belonging to the canopy layer were located on sites with low fern cover, whereas many stems of <i>M. obovata</i> below the canopy layer were associated with sites having high dwarf bamboo cover. The locations of the two <i>Acer</i> species belonging to the canopy and lowest layers coincided with sites having convex topography. Stems of <i>Aesculus turbinata</i> below the canopy layer were generally found on sites with gentle slopes, whereas most stems of <i>Quercus crispula</i> coincided with steeply sloping sites. While the results demonstrate that steep slopes created as landslide headscarps provide suitable habitats for species with less shade tolerance, it should be noted that there were few consistent patterns of habitat association across the layers. Our results suggest that unpredictable sporadic landslide disturbances with varying intensities and spatial scales, and their recursiveness, are at least partly responsible for habitat association patterns observed in the forest community.</p
