Dynamics of Sexual Selection in the Hawaiian Drosophilidae: A Paradigm for Evolutionary Change
TLDR
The dynamics of sexual selection, i.e. changes within the sexual environment of a population, are reviewed as an important driver of evolutionary change especially during the initial stages of species formation.
PRESUMPTIVE RAPID SPECIATION AFTER A FOUNDER EVENT IN A LABORATORY POPULATION OF NEREIS: ALLOZYME ELECTROPHORETIC EVIDENCE DOES NOT SUPPORT THE HYPOTHESIS
TLDR
The Lab population was already a species different from PI and P2 at the time when it was originally sampled in 1964, and is genetically depauperate, most likely as a consequence of the founder event, but this reduced variability contributes only trivially to the genetic differentiation between the populations.
FOUNDER‐FLUSH SPECIATION IN DROSOPHILA PSEUDOOBSCURA: A LARGE‐SCALE EXPERIMENT
TLDR
The results do not support the claim that the founder‐flush‐crash model identifies conditions very likely to result in speciation events, and it is concluded that although founder events may occasionally lead to the evolution of assortative mating and hence to speciation, the claims are not supported.
Bottleneck effects in local populations of fossorial Ctenomys (Rodentia, Ctenomyidae) affected by vulcanism
TLDR
Low levels of genetic variation in Andean Ctenomys, claimed to be an adaptive response to the stable subterranean niche, can be attained by the recurrent catastrophe-induced effects of genetic drift.
The reality and importance of founder speciation in evolution.
  • A. Templeton
  • Biology, Medicine
    BioEssays : news and reviews in molecular, cellular and developmental biology
  • 2008
TLDR
Although rare, founder speciation can have a disproportionate importance in adaptive innovation and radiation, and examples are given to show that "rare" does not mean "unimportant" in evolution.
Peripatric speciation
Peripatric speciation is a mode of speciation in which a new species is formed from an isolated peripheral population.[1]:105 Since peripatric speciation resembles allopatric speciation, in that
EXPERIMENTAL EVIDENCE FOR THE GENETIC‐TRANSILIENCE MODEL OF SPECIATION
  • A. Templeton
  • Biology, Medicine
    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.
The Effects of Selection and Bottlenecks on Male Mating Success in Peripheral Isolates
TLDR
Peripheral isolates formed from single founder events may be expected to show decreased levels of additive genetic variance, altered allele frequencies, and increased homozygosity relative to the preisolation population.
SINGLE FOUNDER‐FLUSH EVENTS AND THE EVOLUTION OF REPRODUCTIVE ISOLATION
TLDR
Results indicate that none of 50 independent founder‐flush lines evolved significant assortative mating relative to the control population, which suggests a diminished emphasis on population bottlenecks in speciation of D. melanogaster and perhaps in general.
Behavioural reproductive isolation and speciation in Drosophila
TLDR
An overview of speciation mediated through behavioural incompatibility in different species groups of Drosophila with particular reference to the models proposed on the basis of one-sided ethological isolation to predict the direction of evolution is documents.

THE FOUNDER‐FLUSH SPECIATION THEORY: AN EXPERIMENTAL APPROACH
  • J. Powell
  • Biology, Medicine
    Evolution; international journal of organic evolution
  • 1978
Stemming from Mayr's (1942; 1954) concept of the "founder principle", Carson (1968; 1971; 1973; 1975) hasdeveloped a somewhat unorthodox theory of speciation. Briefly, Carson views the steps in
ETHOLOGICAL ISOLATION AND PHYLOGENY IN THE PLANITIBIA SUBGROUP OF HAWAIIAN DROSOPHILA
  • K. Kaneshiro
  • Biology, Medicine
    Evolution; international journal of organic evolution
  • 1976
TLDR
The data presented in this paper, measuring the amount of premating reproductive isolation among the four species in "malechoice" experiments, provide basis for the interpretation of phylogenetic relationships of these species.
SEXUAL ISOLATION, SPECIATION AND THE DIRECTION OF EVOLUTION
  • K. Kaneshiro
  • Biology, Medicine
    Evolution; international journal of organic evolution
  • 1980
TLDR
This paper elaborates the hypothesis proposed by Kaneshiro (1976) and proposes a uni-directional phylogeny for the six populations of the grimshawi complex of species.
The Establishment of Novel Mate-Recognition Systems in Introgressive Hybrid Drosophila Populations
TLDR
A preference for mating with a member of one’s own species (ethological isolation) is a necessary feature common to all congeneric species pairs living in sympatry.
The theory of speciation via the founder principle.
TLDR
The genetic transilience model is used to explain several features of the evolution of the Hawaiian Drosophila, and experimental designs are outlined to test the major predictions of the theory.
A STUDY OF SEXUAL ISOLATION BETWEEN CERTAIN STRAINS OF DROSOPHILA PAULISTORUM
TLDR
It appears to be a general rule that where two or more of the incipient species are sympatric in the same territory, no hybrids between them are formed spontaneously, and crosses can be made in laboratory experiments only with considerable difficulty, always yielding sterile hybrids.
Measurement of sexual isolation and selective mating.
TLDR
The recent biological definitions of species have stressed the attainment of reproductive isolation between two populations as the critical step in speciation, so it is desirable to have some simple means of comparing the results from the different types of mating experiments.
DOES ASYMMETRICAL MATING PREFERENCE SHOW THE DIRECTION OF EVOLUTION?
TLDR
The results of a study made on the DrosophILA arizonensis-Drosophila majavensis species pair are used, which found a much higher level of sexual isolation between sympatric populations of the two species.
Ethological isolation among three species of the planitibia subgroup of Hawaiian Drosophila.
TLDR
The ethological isolation and the hybrid sterility are uncorrelated, expected if premating isolation between closely related species is an ad hoc product of natural selection, while postmating isolation is an incidental result of genetic divergence.
Speciation as a Stage in Evolutionary Divergence
TLDR
A theory is suggested according to which the development of isolating mechanisms follows, rather than accompanies, that of the adaptive complexes themselves, which suggests that speciation is meant the fixation of discontinuity among organisms.
