Review Article Sympatric Speciation as a By-product of Ecological Adaptation in the Galician Littorina Saxatilis Hybrid Zone
On exposed rocky shores in northwestern Spain there is a striking polymorphism of Littorina saxatilis that has been claimed as an example of a putative sympatric ecological speciation process. Two ecotypes of this species have evolved that are adapted to different shore levels and habitats, although they meet and hybridize on the mid shore where their two habitats overlap. As a by-product of ad...
متن کاملThree chromosomal rearrangements promote genomic divergence between migratory and stationary ecotypes of Atlantic cod
Identification of genome-wide patterns of divergence provides insight on how genomes are influenced by selection and can reveal the potential for local adaptation in spatially structured populations. In Atlantic cod - historically a major marine resource - Northeast-Arctic- and Norwegian coastal cod are recognized by fundamental differences in migratory and non-migratory behavior, respectively....
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 کاملChromosomal rearrangements in cancer
Many cancers exhibit chromosomal rearrangements. These rearrangements can be simple with a single balanced fusion preserving the proper complement of genetic information or they can be complex with one or more fusions that distort this balance. A range of technological advances has improved our ability to detect and understand these rearrangements leading to speculation of causal mechanisms inc...
متن کاملSteep difference between ecotypes and intermediate phenotype depression for shell trait integration in a marine snail hybrid zone
Multivariate analyses of phenotypic integration for a set of characters provide information about biological systems that cannot be obtained in univariate studies of these characters. We studied phenotypic integration for seven shell measures across the phenotypic gradient in a hybrid zone of the marine snail Littorina saxatilis in Galicia, NW Iberia. We found clear differences in the degree of...
