Phytosociological Study and Spatial autocorrelation on the Forest Vegetation of Mt. Yeonae at Gijang-gun 원문보기

Mt. Yeonae is at Gijang-gun in Busan and is surrounded by farming lands on three sides. The search for the species composition and dynamics of local communities were studied at Mt. Yeonae of how spatial similarity decays with geographic distance. The index values of Z$\ddot{u}$rich-Montpellier School's phytosociology at the 12 plots was compared to a distribution of similarly using 20 m quadrates at 12 sites. The specific communities were five including Pinus densiflora - Quercus variabilis community. Six species were significant similarity between neighboring sites by using the spatial autocorrelation coefficient, Moran's I. If Mt. Yeonae was destroyed by an artificial action, some spatial correlated species such as P. densiflora and Q. variabilis will be collapsed because of no maintaining the effective population sizes.

가설 설정

We asked the question, Are the plant species in local communities more or less related than expected if such communities were formed from a random sampling of available species in the larger area?

제안 방법

In this article, we describe general methods for quantifying the phylogenetic structure of local communities of interacting organisms (relative to a shared species pool) and use data from a forest community in Mt. Yeonae (149.5 m) at Gijang-gun in Busan as an example of how this method can be used to address questions of community organization. Recently, the new road which is situated between Mt.

대상 데이터

The data set consisted of trees and herb species sampled in 12 sites or plots (20 m x 20 m) in forest at Mt. Yeonae. The plots were scattered in a 50 m stratified sampling design and contained 49 species.
Yeonae. The plots were scattered in a 50 m stratified sampling design and contained 49 species.

이론/모형

Clustering of sites, using the Neigboring-joining algorithm, was performed based on the matrix of calculated distances (Fig. 2). The phylogenic tree showed three distinct clades.
The spatial structure of locus variations was quantified by Moran's I, a coefficient of spatial autocorrelation (SA) (Sokal and Oden, 1978a).

성능/효과

The other includes three communities, Pinus densiflora – Quercus community, Alnus firma community, and Pinus densiflora – Styrax japonica community. The last clade was Chamaecyparis obtusa afforestation.
Chamaecyparis obtusa at sites D was the dominant species in r-NCDi. The second and third dominant species in r-NCDi were Zanthoxylum schinifolium (46.7%) and Juniperus rigida (40.0%), respectively.
Quercus serrata at sites F was the dominant species in r-NCDi. The second dominant species in r-NCDi were Pinus densiflora (53.8%) and Styrax japonica (53.8%).
Alnus firma was the dominant species at sites B with high r-NCDi (100%). The second dominant species in tree layer were Pinus densiflora (42.9%), Carpinus laxiflora (42.9%), and Prunus sargentii (42.9%).

용어 설명: PCR은 세균 특이성이 있는 primer를 이용하여 적은 수의 세균이 있을지라도 쉽게 검출할 수 있는 유용한 방법이며, 이를 이용하여 구강 내 치면세균막이나 타액에서 직접 세균을 검출할 수 있게 되었다[8].
