“…The total number of alleles (n a ), allelic frequencies, and Shannon index were estimated for each locus using the program POPGENE (Yang & Yeh, 1993). Observed (H O ) and expected (H E ) heterozygosities were calculated for each locus (Raymond & Rousset, 1995).…”

The catadromous Japanese eel has an unusual life history. Controversy remains, however, as to whether its population structure is characterized by panmixia or genetic differentiation. Migration patterns are considered an important factor in determining a species' population structure. Eight polymorphic microsatellite loci were used as genetic markers through which we were able to reject the null hypothesis of panmixia. Slight genetic differentiation between these populations was determined by Wright's and Slatkin's fixation indices, F ST and R ST statistics adjusted using Bonferroni's correction. Although isolation-by-distance is often observed in marine species, the present result is thought to follow the member-vagrant migratory hypothesis. The metapopulation model fits the elver recruitment strategy according to results of the high probability of assignment test. The UPGMA tree showed the Japanese eel populations as being divided into 2 groups: a low-latitude group (Shantou in South China, and Tanshui and Fangliao in Taiwan) and a high-latitude group (Mikawa Bay in Japan, Daecheon-myon in Korea, and the Yalu River and Hangzhou in Northeast China). Temporal genetic variations indicate that most progeny return to similar habitats where their ancestors formerly resided. There was a high correlation (AMOVA; p < 0.05) when the Japanese eel was divided into the 2 management units (high-and low-latitude groups). These units will be useful when applied to fisheries conservation and management in the northwestern Pacific Ocean.

“…Almost all of the significant values involved loci PER or PGM, for which they found some evidence of natural selection. Finally, Yang & Yeh (1993) found an extensive gametic disequilibrium in 40 out of 60 populations of three subspecies of Pinus contorta, thought to result from a multilocus Wahlund effect after fire establishment.…”

We report the results of the screening of 20 mapped RAPD loci over haploid megagametophytes from 48 individual trees of an Italian population of Norway spruce. LOD scores for 190 pairs of loci were calculated over families of megagametophytes from 'informative' trees, and linkage relationships between pairs of markers were analysed. Single-locus genotypes were inferred from haploid progeny-array data and were used to estimate linkage disequilibrium between loci. Significant deviations from equilibrium did not appear to be randomly distributed over loci. Most of the markers analysed showed an excess of heterozygotes and five out of 20 RAPD markers showed significant deviations from Hardy-Weinberg equilibrium. A weak spatial structure was detected by spatial autocorrelation at the scale considered (0-180 m), suggesting a lack of 'family structure' arising from isolation by distance. Nonrandom distribution of the genetic variability was limited to some loci. Di-and tn-locus spatial autocorrelation of loci showing linkage disequilibrium was also carried out.
