摘      要：The dogwhelk Nucella lapillus is a predatory marine gastropod living on rocky shores in the North *** with many other gastropod species,Nucella was affected by tributyltin(TBT)pollution during the 1970s and 1980s,and local populations underwent *** a partial ban on TBT in the UK in 1987,vacant sites have been *** of genetic diversity and quantitative genetic variation in shell form were compared between recolonized sites and sites that showed continuous population at three localities across the British ***,estimates of genetic diversity were only slightly lower in recolonized populations,suggesting that populations have recovered from previous impacts due to the relatively high levels of migration from non-impacted *** and quantitative analyses are broadly concordant and a positive correlation was observed(although not statistically significant)between molecular and quantitative estimates of genetic diversity,indicating the potential usefulness of quantitative methods to complement molecular population genetics analyses.
