Microscale genetic differentiation along the vertical shore gradient in White Sea snails Littorina saxatilis (Olivi) assessed by microsatellite markers
helix. We conclude that for samples critical for DNA extraction, drowning must not be used as a method of relaxation and that cooling the samples during drowning does not improve the conditions. For studies that require material for both histological/ dissection and molecular purposes, we suggest that a tiny piece of tissue is cut from the animals prior to the drowning and placed in 10–20 vols ...
متن کاملHigh levels of multiple paternity in Littorina saxatilis: hedging the bets?
The mating system of a species can have great effects on its genetic structure and evolution. We studied the extent of multiple paternity in a gastropod with internal fertilization, the intertidal snail Littorina saxatilis. Paternal genotype reconstruction based on microsatellite markers was performed on the offspring of wild, naturally fertilized females from 2 populations. The numbers of male...
متن کاملAn EST-based genome scan using 454 sequencing in the marine snail Littorina saxatilis.
Genome scans have been used in the studies of ecological speciation to find genomic regions ('outlier loci') showing reduced gene flow between divergent populations/species. High-throughput sequencing ('454') offers new opportunities in this field via transcriptome sequencing. Divergent ecotypes of the marine gastropod Littorina saxatilis represent a good example of incipient ecological speciat...
متن کاملDo the same genes underlie parallel phenotypic divergence in different Littorina saxatilis populations?
Parallel patterns of adaptive divergence and speciation are cited as powerful evidence for the role of selection driving these processes. However, it is often not clear whether parallel phenotypic divergence is underlain by parallel genetic changes. Here, we asked about the genetic basis of parallel divergence in the marine snail Littorina saxatilis, which has repeatedly evolved coexisting ecot...
متن کاملThe evolutionary forces maintaining a wild polymorphism of Littorina saxatilis: model selection by computer simulations.
Two rocky shore ecotypes of Littorina saxatilis from north-west Spain live at different shore levels and habitats and have developed an incomplete reproductive isolation through size assortative mating. The system is regarded as an example of sympatric ecological speciation. Several experiments have indicated that different evolutionary forces (migration, assortative mating and habitat-dependen...
