Genomic signatures of the plateless phenotype in the threespine stickleback
Understanding the genetic basis of traits involved in adaptive divergence and speciation is one of the most fundamental objectives in evolutionary biology. Toward that end, we look for signatures of extreme plate loss in the genome of freshwater threespine sticklebacks (Gasterosteus aculeatus). Plateless stickleback have been found in only a few lakes and streams across the world; they represen...
متن کاملNiche specialization influences adaptive phenotypic plasticity in the threespine stickleback.
Phenotypic plasticity may be favored in generalist populations if it increases niche width, even in temporally constant environments. Phenotypic plasticity can increase the frequency of extreme phenotypes in a population and thus allow it to make use of a wide resource spectrum. Here we test the prediction that generalist populations should be more plastic than specialists. In a common-garden e...

متن کاملGene expression plasticity evolves in response to colonization of freshwater lakes in threespine stickleback.
Phenotypic plasticity is predicted to facilitate individual survival and/or evolve in response to novel environments. Plasticity that facilitates survival should both permit colonization and act as a buffer against further evolution, with contemporary and derived forms predicted to be similarly plastic for a suite of traits. On the other hand, given the importance of plasticity in maintaining i...
متن کاملThe Evolutionary Biology of the Threespine Stickleback
Because the study of variability lies at the heart of evolutionary biology, species that exhibit considerable variation across their geographic range are of special interest to comparative biologists interested in understanding evolutionary patterns and processes at the species level. Few vertebrates match threespine sticklebacks (Gasterosteus aculeatus) in the extent of geographic variation in...
