Glacial History of the North Atlantic Marine Snail, Littorina saxatilis, Inferred from Distribution of Mitochondrial DNA Lineages
The North Atlantic intertidal gastropod, Littorina saxatilis (Olivi, 1792), exhibits extreme morphological variation between and within geographic regions and has become a model for studies of local adaptation; yet a comprehensive analysis of the species' phylogeography is lacking. Here, we examine phylogeographic patterns of the species' populations in the North Atlantic and one remote Mediter...
متن کاملPolymorphic microsatellite DNA markers in the penduline tit, Remiz pendulinus.
To describe the exceptional mating system of the penduline tit, Remiz pendulinus, we aim to combine field observation records with DNA analysis based on polymorphic microsatellite DNA markers. Here we describe features of nine loci and their corresponding polymerase chain reaction primers. The observed number of alleles varied from four to seven and the observed heterozygosity ranged from 0.419...

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 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 کاملAccumulation of Aqueous and Nanoparticulate Silver by the Marine Gastropod Littorina littorea
The accumulation of Ag by the marine herbivorous gastropod, Littorina littorea, has been studied in a series of exposures in which the metal was added in aqueous form and as nanoparticles, both in the presence and absence of contaminated algal food (Ulva lactuca). Significant accumulation occurred in the gill, kidney, stomach and visceral mass when the snail was exposed to aqueous Ag in the abs...
