We present evidence of ecological character displacement among species of threespined sticklebacks that inhabit small lakes of coastal British Columbia. Geological data suggest that the populations resulted from multiple divergence and speciation events over the past 13,000 yr. In lakes with two species, one is invariably "limnetic" in morphology and habitat, and the other is "benthic." Other lakes contain a single form morphologically intermediate between sympatric species and exploiting both… 
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.
Ecological Speciation in Postglacial Fishes
TLDR
It is argued that knowledge of ecological environments is essential to understanding the origin of species in adaptive radiation, and perhaps more generally to complement (and perhaps transform) traditional genetic approaches to speciation.

Invasive species can be powerful models for studying contemporary evolution in natural environments. As invading organisms often encounter new habitats during colonization, they will experience novel
A TEST OF ECOLOGICALLY DEPENDENT POSTMATING ISOLATION BETWEEN SYMPATRIC STICKLEBACKS

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.
Ecological opportunity and levels of morphological variance within freshwater stickleback populations
TLDR
Examining morphological diversity within stickleback populations in 40 undisturbed lakes from six islands off the mid-coast of British Columbia, Canada suggested that character release can be trait-specific and reflect the combined effects of competition, predation and habitat heterogeneity.
Character Release and Displacement in Fishes: A Neglected Literature
TLDR
It is shown that competition is frequently a diversifying force that creates differences between species and differences within species when other closely related species are absent, and the lake environment can be viewed as a set of non-Hutchinsonian or "environmental" niches that exist apart from the species that occupy them.
ECOLOGICAL SPECIATION IN STICKLEBACKS: ENVIRONMENT‐DEPENDENT HYBRID FITNESS
  • T. Hatfield, D. Schluter

  • 1999
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.
Environmental determinants of threespine stickleback species pair evolution and persistence
TLDR
This study suggests that colonization history rather than unique lake attributes facilitated the evolution of stickleback species pairs and that the fish assemblage in lakes may affect resource availability and speciation potential as strongly as the limnological attributes of the lakes themselves.
Genetic and morphometric divergence in threespine stickleback in the Chignik catchment, Alaska
TLDR
The genetic and morphometric differentiation between sticklebacks living in an open system comprising a brackish water lagoon, two freshwater lakes, and connecting rivers is examined and it appears that some pre-and/or postzygotic barriers to gene flow rather than geographic distance are causing the divergence.
FREQUENCY DEPENDENT NATURAL SELECTION DURING CHARACTER DISPLACEMENT IN STICKLEBACKS
  • D. Schluter
  • Biology, Environmental Science

  • 2003
TLDR
Results provide further support for the hypothesis of character displacement in sympatric sticklebacks and suggest that displacement along the resource gradient also led to divergence in vulnerability to agents of mortality, probably including predation.

EVIDENCE FOR ECOLOGICAL CHARACTER DISPLACEMENT IN WESTERN AMERICAN CATOSTOMID FISHES
TLDR
The weakness of the available evidence for competitive character displacement lies in the difficulty of establishing unambiguously that the character state of a species changes under natural selection arising from the presence of one or more species similar to it ecologically.
Character Displacement and Biogeography of the Pygmy Shrew in Northern Europe
TLDR
It is suggested that late—Quaternary zoogeographic patterns during periods of low sea level can explain the present distribution of allopatric pygmy shrew populations.
A PHYLOGENETIC ANALYSIS OF CHARACTER DISPLACEMENT IN
TLDR
Analysis of Anolis lizards in the Lesser Antilles in a phylogenetic context suggests that size assortment might be responsible for non-random patterns, and assesses evidence for size adjustment by partitioning changes in size along branches of the phylogenetic tree.
INTER- AND INTRASPECIFIC CHARACTER DISPLACEMENT IN MUSTELIDS'
TLDR
It seems unlikely that canine use could account for the entire pattern of size ratio equality, as it would be quite coincidental that size ratios sexually selected between sexes within species should happen to equal those, however selected, between the male of each species and the female of the next larger species.
Character Displacement and the Adaptive Divergence of Finches on Islands and Continents
TLDR
It is shown that the amount of divergence is greater in the Galapagos and Hawaiian finches, even when only beak-size divergence in the granivorous component is considered, suggesting that community-wide character displacement involving many taxa is common.
Rapid Evolution of Character Displacement in Myzomelid Honeyeaters
TLDR
It is concluded that the size shifts in myzomelids on the Long group probably represent character displacement in response to each other's presence and that the shifts evolved in the approximately three centuries since Long's eruption.

TLDR
Two morphologically distinct species of threespine stickleback coexist in Enos Lake on Vancouver Island and the hypothesis that limnetics is adapted for planktivory whereas benthics are adapted to forage on substrates is tested.

The Systematics of Salmonid Fishes of Recently Glaciated Lakes
TLDR
The systematics of the subfamilies Salmoninae and Coregoninae of recently glaciated regions are reviewed, and examples are cited to support the contention that many sympatric "sibling species" have evolved from a common ancestor in postglacial times.
Ecological Character Displacement in a Lizard
TLDR
Morphological and dietary evidence support the hypothesis that behavioral and morphological character displacement has occurred in female and immature T. lineatus, which reduces dietary overlap with T. gariepensis .
