Abstract Population differentiation often reflects a balance between divergent natural selection and the opportunity for homogenizing gene flow to erode the effects of selection. However, during ecological speciation, trait divergence results in reproductive isolation and becomes a cause, rather than a consequence, of reductions in gene flow. To assess both the causes and the reproductive consequences of morphological differentiation, we examined morphological divergence and sexual isolation… 
The role of selection and gene flow in the evolution of sexual isolation in Timema walking sticks and other Orthopteroids
TLDR
Variation among groups might reflect the degree to which different groups are intimately associated with their food resources, the types of traits used in mate choice, and how the geographic arrangement of populations affects the opportunity for reinforcement.
Dimensionality of sexual isolation during reinforcement and ecological speciation in Timema cristinae stick insects
TLDR
If sexual isolation tends to have a strong upper limit to its dimensionality, as observed in the dataset, levels of divergence sufficient for speciation may require multiple forms of reproductive isolation.
Fine‐grained adaptive divergence in an amphibian: genetic basis of phenotypic divergence and the role of nonrandom gene flow in restricting effective migration among wetlands
TLDR
It is demonstrated that while the study area did not exceed the scale of gene flow, ecological barriers constrained gene flow among contrasting habitats, highlighting the roles of strong selection and nonrandom gene flow created by phenological variation and, possibly, habitat preferences, which together maintain genetic and phenotypic divergence at a fine‐grained spatial scale.
Microgeographic morphological variation across larval wood frog populations associated with environment despite gene flow
  • A. Zellmer

  • 2018
TLDR
Results suggest that morphological divergence among these wood frog populations is occurring despite gene flow and that selection within these environments is strong, demonstrating the importance of evaluating phenotypic divergence over multiple time periods and at a time relevant to the processes being studied.
DIFFERENTIATION BETWEEN TWO SALT MARSH BEETLE ECOTYPES: EVIDENCE FOR ONGOING SPECIATION
TLDR
It is concluded that speciation is ongoing and that divergence reflects a balance between selection and gene flow, and was consistent with patterns seen across western European populations.
Ecological selection as the cause and sexual differentiation as the consequence of species divergence?
  • E. Oneal, L. Knowles
  • Biology, Medicine
    Proceedings of the Royal Society B: Biological Sciences
  • 2013
TLDR
Tests based on speciation theory and analysis of divergent ecological selection, sexually selected differentiation and geographical isolation find that all three factors contribute to divergence, and that their interaction determines the stage of completeness achieved during the speciation process, as measured by patterns of genetic differentiation.
Sexual dimorphism dominates divergent host plant use in stick insect trophic morphology
TLDR
The results show that trophic morphology does not strongly contribute to host-adapted ecotype divergence in T. cristinae and that traits can respond to complex selection regimes by diverging along different intraspecific lines, thereby impeding progress toward speciation.
RADseq and mate choice assays reveal unidirectional gene flow among three lamprey ecotypes despite weak assortative mating: Insights into the formation and stability of multiple ecotypes in sympatry
TLDR
It is found that multiple lamprey ecotypes can persist in sympatry following shifts in adaptive peaks, due to environmental change during their repeated colonization of post‐glacial regions, followed by periods of extensive gene flow among such diverging populations.
Repeated and predictable patterns of ecotypic differentiation during a biological invasion: lake–stream divergence in parapatric Swiss stickleback
TLDR
Evidence is found that adaptive phenotypic divergence places constraints on gene flow over and above that imposed by geographical distance, signalling the early onset of ecological speciation.
Does behavioral isolation prevent interspecific mating within a parallel ecotypic wolf spider radiation from the Galápagos?
TLDR
Despite low acceptance rates, heterospecific mating was observed, suggesting that potential gene flow within as well as among islands should not be neglected when seeking to understand island radiations.

CORRELATED TROPHIC SPECIALIZATION AND GENETIC DIVERGENCE IN SYMPATRIC LAKE WHITEFISH ECOTYPES (COREGONUS CLUPEAFORMIS): SUPPORT FOR THE ECOLOGICAL SPECIATION HYPOTHESIS
  • G. Lu, L. Bernatchez
  • Biology, Medicine

  • 1999
TLDR
The extent of reproductive isolation reached between dwarf and normal whitefish ecotypes appears to be driven by the potential for occupying distinct trophic niches and, thus, by the same selective forces driving tropic specialization in each lake, which support the hypothesis of ecological speciation.
Divergent selection maintains adaptive differentiation despite high gene flow between sympatric rainbow smelt ecotypes (Osmerus mordax Mitchill)
TLDR
While divergent selection has apparently been strong enough to maintain phenotypic differentiation in the face of migration, this study suggests that gene flow has been sufficiently important to modulate the extent of adaptive differentiation being achieved between ecotypes, unless the amount of stabilizing selection acting on smelt ecotypes is much more pronounced than usually reported in natural populations.
Reproductive isolation driven by the combined effects of ecological adaptation and reinforcement
TLDR
These findings demonstrate the joint effects of reinforcement, ecological adaptation and gene flow on progress towards speciation in the wild in Timema cristinae walking-stick insects.
High gene flow levels lead to gamete wastage in a desert spider system
TLDR
Punnett square analyses of the potential genotypes produced by introgression between arid- and riparian-adapted spiders indicate that these extreme phenotypes appear in F2 generation hybrids and backcrosses.
Host-plant adaptation drives the parallel evolution of reproductive isolation
TLDR
It is reported that divergent selection for host adaptation, and not genetic drift, has promoted the parallel evolution of sexual isolation in this species, a clear demonstration that host-plant adaptation can play a crucial and repeatable role in the early stages of speciation.
HYBRIDIZATION STUDIES ON THE HOST RACES OF EUROSTA SOLIDAGINIS: IMPLICATIONS FOR SYMPATRIC SPECIATION
TLDR
Evidence is found for disruptive selection for host use, which is a critical assumption of sympatric speciation models, and high survival of F1, F2, and backcross hybrids on some plant genotypes in some years supported the host adaptation hypothesis.

TLDR
Two morphs of the walking‐stick Timema cristinae were each strongly associated with patches of distinct species of food plants on which they are most cryptic, and result (3) is consistent with Levene's multiple‐niche polymorphism model.

TLDR
A reversal of relative fitness of the two cross‐types in the two environments provides strong evidence that divergent natural selection has played a central role in the evolution of postmating isolation between Benthics and Limnetics.
