AFLPs reveal different population genetic structure under contrasting environments in the marine snail Nucella lapillus L.

Dispersal has received growing attention in marine ecology, particularly since evidence obtained with up-to-date techniques challenged the traditional view. The dogwhelk Nucella lapillus L., a sedentary gastropod with direct development, is a good example: dispersal was traditionally assumed to be l...
