The genetic and molecular basis of morphological evolution is poorly understood, particularly in vertebrates. Genetic studies of the differences between naturally occurring vertebrate species have been limited by the expense and difficulty of raising large numbers of animals and the absence of molecular linkage maps for all but a handful of laboratory and domesticated animals. We have developed a genome-wide linkage map for the three-spined stickleback (Gasterosteus aculeatus), an extensively… 

Genomics of adaptation revealed in threespine stickleback

TLDR
The main model organism is the threespine stickleback fish and it is demonstrated that the repeated occurrence of similar stream phenotypes are, in this particular system, better explained by an evolutionary scenario of 'ecological vicariance' rather than repeated parallel divergence.

TLDR
This work has provided answers to four longstanding questions in the field of evolution and development and extended the approaches used to identify the genetic basis of morphological variation in sticklebacks to other phenotypes is sure to yield further important insights into the genetic and developmental basis of diversity in natural populations.

The Population Genomics of Parallel Adaptation: Lessons from Threespine Stickleback

TLDR
This work reviews results and assess alternative modes for the genetic basis of parallel phenotypic adaptation in threespine stickleback in terms of the genetic architecture of the traits and the source of adaptive variation across populations.

New genomic tools for molecular studies of evolutionary change in threespine sticklebacks

TLDR
A number of genomic and genetic tools should make it possible to identify the molecular basis of many different evolutionary traits in stickleback, and to begin to answer longstanding questions about the numbers and types of mutations that control the appearance of new morphological, physiological, and behavioral traits during vertebrate evolution.

Genetic Architecture of Variation in the Lateral Line Sensory System of Threespine Sticklebacks

TLDR
A complex genetic architecture underlying the evolution of the stickleback lateral line sensory system is revealed, and a genetic relationship between sensory morphology and non-neural traits (bony lateral plates) is uncovered, creating an opportunity to investigate morphological constraints on sensory evolution in a vertebrate model system.

The genetic and molecular architecture of phenotypic diversity in sticklebacks

TLDR
Genetic and molecular studies in sticklebacks have led to new insights on the genetic basis of repeated evolution and suggest that the same loci are involved about half of the time when the same phenotypes evolve independently.

Parallel genetic basis for repeated evolution of armor loss in Alaskan threespine stickleback populations.

TLDR
Rapid and repeated armor loss in Alaskan stickleback populations appears to be occurring through the fixation of large-effect variants in the same genes, implicating the same Mendelian armor reduction genes.

The genomic basis of adaptive evolution in threespine sticklebacks

TLDR
A high-quality reference genome assembly for threespine stickleback fish is developed and it is indicated that reuse of globally shared standing genetic variation has an important role in repeated evolution of distinct marine and freshwater sticklebacks, and in the maintenance of divergent ecotypes during early stages of reproductive isolation.

Morphological and genetic divergence of intralacustrine stickleback morphs in Iceland: a case for selective differentiation?

TLDR
Variation in neutral markers, markers linked to putative quantitative trait loci and morphological traits in a recent zone of primary divergence between stickleback morphs in Lake Thingvallavatn, Iceland indicate that the morphs have diverged at several loci.

Genetic basis of sexual dimorphism in the threespine stickleback Gasterosteus aculeatus

TLDR
The results show that genetic architecture in terms of heritabilities, additive genetic variances and covariances (as well as correlations) is very similar in the two sexes in spite of the fact that many of the traits express significant SD.

Axial variation in the threespine stickleback: genetic and environmental factors

TLDR
It is demonstrated that considerable genetic variation for axial morphology is maintained in natural populations of threespine stickleback, and that differences between populations may be brought about rapidly by changes in frequency of alleles that have coordinated effects along the body axis.

TLDR
The following is a study of selection operating in the form of predation on the unusual characteristics of the Black stickleback.

Genetic Divergence in Adaptive Characters Between Sympatric Species of Stickleback

TLDR
The results suggest that adaptive divergence between limnetic and benthic sticklebacks has taken place through a variety of genetic mechanisms specific to different traits.

GEOGRAPHIC VARIATION AND ENVIRONMENTAL SELECTION IN GASTEROSTEUS ACULEATUS L. IN THE PACIFIC NORTHWEST, AMERICA

TLDR
This report is a preliminary investigation of geographic variation in permanent freshwater populations of G. aculeatus, excluding the marine trachurus, and seeks to establish correlations of phenotype with environmental variables, where they exist, applying the techniques so profitably exploited by ecological geneticists.

ECOLOGICAL SPECIATION IN STICKLEBACKS: ENVIRONMENT‐DEPENDENT HYBRID FITNESS

TLDR
The contrast between laboratory and field results supports the hypothesis that mechanisms of F1 hybrid fitness in the wild are primarily ecological and do not result from intrinsic genetic incompatibilities.

BODY SIZE, NATURAL SELECTION, AND SPECIATION IN STICKLEBACKS

TLDR
Interspecific mate preferences in sympatric sticklebacks appears to be dominated by body size, implicating natural selection in the origin of species.

Adaptive Radiation in Sticklebacks: Size, Shape, and Habitat Use Efficiency

TLDR
The hypothesis that different traits are favored in different habitats, and that adaptation to one habitat has occurred at the expense of feeding rate in the other, is supported.

Genetic linkage of ecological specialization and reproductive isolation in pea aphids

TLDR
A model of the role of genetic correlations in specialization and speciation is presented, and several complexes of pleiotropic or closely linked quantitative trait loci that affect key traits in ways that would promote speciation are found.

TLDR
This work has shown that speciation and the evolution of reproductive isolation in the sticklebacks of south-western British Columbia are connected and the value of viewing evolution through stickleback-tinted glasses is illustrated.

Ecology and evolution of sympatric sticklebacks (Gasterosteus): mate choice and reproductive isolation in the Enos Lake species pair

TLDR
Field observations, mate choice experiments, and courtship experiments were conducted to determine if courtship behaviour contributes to reproductive isolation between these two species of sticklebacks.
