Spatial autocorrelation
 
Description 635-641
The
spatial autocorrelation of allelic frequencies and geographical distances were
studied at a natural population of Codium fragile in Korea. Within the C. fragile
population, a strong spatial structure was observed for allozyme markers,
indicating a very low amount of migration among subpopulations. The species
showed a significant positive spatial autocorrelation as measured by Moran's I.
Genetic similarity of individuals was found among subpopulation at up to a
scale of 250 m distances. This was partly due to a combination of allelic
frequencies.  Hence a significant spatial
autocorrelation was composed of a scale of 250 m intervals. The distribution of
allelic frequencies of C. fragile at eleven Geoje
Island subpopulations in Korea
was related to mating systems such as sexual reproduction. Present study
demonstrates that analysis of allozyme markers can successfully be used to
study the spatial structure and genetic structure of C. fragile.
