If colonizing populations are displaced into an environment that is often very different from that of their source1, they are particularly likely to diverge evolutionarily, the more so because they are usually small and thus likely to change by genetic restructuring or drift2,3. Despite its fundamental importance, the consequence of colonization for traits of founding populations have primarily been surmised from static present-day distributions1,2,4,5, laboratory experiments6 and the outcomes… Expand
Experimental studies of adaptive differentiation in Bahamian Anolis lizards
Populations of the lizards Anolis carolinensis and A. sagrei were experimentally introduced onto small islands in the Bahamas. Less than 15 years after introduction, we investigated whether theExpand

Genetic consequences of an introduction‐colonization process in an endangered butterfly species
TLDR
The results show that this colonization of Proclossiana eunomia females released in a region where this glacial relict was absent was a success, despite a predicted loss of polymorphism. Expand
Phylogeographic and phenotypic outcomes of brown anole colonization across the Caribbean provide insight into the beginning stages of an adaptive radiation
TLDR
The results show a complex history of ancient and recent Cuban diaspora with populations on competitor‐poor islands evolving away from their ancestral Cuban populations regardless of their phylogenetic relationships, thus providing insight into the original diversification of colonist anoles at the beginning of the radiation. Expand
Founder Effects Persist Despite Adaptive Differentiation: A Field Experiment with Lizards
TLDR
It is shown that both founder effects and natural selection jointly determine trait values in these populations of anoles, which shows that evolution occurs by a combination of arbitrary events, as well as those shaped by selection. Expand
Contemporary fisherian life-history evolution in small salmonid populations
TLDR
It is shown that natural selection was the dominant diversifying agent in the evolution of the quantitative traits in isolated populations of grayling that originated from a common source 80–120 years ago. Expand
The Role of Phenotypic Plasticity in Marine Biological Invasions
TLDR
Phenotypic plasticity can provide a mechanistic explanation to understand and predict why and how some individuals or species invade and others do not, and what the ecological effects and eventual ranges of the invader might be, and how native species might respond to the introduction. Expand
HISTORICAL DIVERSIFICATION OF MIGRATION PATTERNS IN A PASSERINE BIRD
TLDR
The results show that the interruption of gene flow between migratory and sedentary populations is not necessary for the maintenance of such a polymorphism, and that even the most divergent migratory strategies of a bird species are susceptible to evolution in response to historical environmental changes. Expand

TLDR
The results show that the interruption of gene flow between migratory and sedentary populations is not necessary for the maintenance of such a polymorphism, and that even the most divergent migratory strategies of a bird species are susceptible to evolution in response to historical environmental changes. Expand
Fine-scale local adaptation in an invasive freshwater fish has evolved in contemporary time
TLDR
The results combine to indicate that adaptive divergence—reflected by higher relative survival of local individuals—can occur in a small number of generations and only a few kilometres apart on the landscape. Expand

The time to extinction of a colonizing propagule of lizards increases with island area
TLDR
In the present study with lizards, both island area and propagule size were varied experimentally in an attempt to separate their effects, showing that for a given species, time to extinction increased with island area in a monotonic fashion. Expand
Morphometric analyses of introduced and ancestral populations of the Eurasian tree sparrow
TLDR
The North American population shows no significant decrease in intrinsic morphometric variation corresponding to the decrease in genetic variation demonstrated in comparison to German birds, and significant differences in bill morphology are found between German and North American P. montanus.

TLDR
It is argued that local adaptation within “ancestral” populations in northern Europe may still be evolving, and longer term adaptive differentiation via selection for optimal body size has evolved in Europe. Expand
Experimentally Induced Morphological Diversity in Trinidadian Guppies (Poecilia reticulata)
TLDR
Morphological differences in males between the floating and bottom feeders correspond, respectively, to open water (fusiform) and benthic (deeper-bodied) forms described both among and within many fish species. Expand
EXPERIMENTAL EVIDENCE FOR THE GENETIC‐TRANSILIENCE MODEL OF SPECIATION
  • A. Templeton

  • Evolution; international journal of organic evolution
  • 1996
TLDR
This conclusion is flawed because the most relevant papers in the experimental literature on this topic are not cited by Rice and Hostert (1993), internally inconsistent criteria for evaluation are used in the contrast of bottleneck models versus the other speciation models, and the predictions of the genetic-transilience model of speciation are inaccurately portrayed.
