SYMPATRIC HOST RACE FORMATION AND SPECIATION IN FRUGIVOROUS FLIES OF THE GENUS RHAGOLETIS (DIPTERA, TEPHRITIDAE)
  • G. Bush
  • Biology, Medicine
  • Evolution; international journal of organic…
  • 1 June 1969
TLDR
The objective of this paper is to point out how the biological attributes of these flies may have permitted new forms to arise rapidly in the absence of geographical barriers to gene flow. Expand
Sympatric speciation in animals: new wine in old bottles.

  • 1 August 1994
TLDR
The initiation of speciation through a habitat shift in animals which mate within a preferred habitat (such as many phytophagous and parasitic invertebrates and some vertebrates) requires few genetic changes. Expand
Rapid speciation and chromosomal evolution in mammals.
TLDR
Speciation and chromosomal evolution seem fastest in those genera with species organized into clans or harems or with limited adult vagility and juvenile dispersal, patchy distribution, and strong individual territoriality, consistent with the above hypothesis regarding the evolutionary importance of demes.

An Evolutionary and Applied Perspective of Insect Biotypes
TLDR
A classification system of insect biotypes, based on the mechanisms underlying their differentiation, is outlined below, and the significance of biotypes in adaptation, speciation, and pest management is considered. Expand
Sympatric Speciation in Phytophagous Parasitic Insects
TLDR
The appearance of new insect pests on economically important plants is a well-known phenomenon, but populations of introduced or native insects are frequently encountered which exhibit different host preferences, but which are morphologically indistinguishable from one another. Expand
Genetic differentiation between sympatric host races of the apple maggot fly Rhagoletis pomonella
TLDR
The result confirms that hawthorn and apple flies represent partially reproductively isolated 'host races' and is consistent with a sympatric mode of divergence for these flies. Expand
Speciation in fig pollinators and parasites
Here we draw on phylogenies of figs and fig wasps to suggest how modes of speciation may be affected by interspecific interactions. Mutualists appear to have cospeciated with their hosts to a greaterExpand
Phylogeny of the genus Rhagoletis (Diptera: Tephritidae) inferred from DNA sequences of mitochondrial cytochrome oxidase II.
  • J. Smith, G. Bush
  • Biology, Medicine
  • Molecular phylogenetics and evolution
  • 1 February 1997
TLDR
The phylogenetic history of 28 Rhagoletis species and 6 species in related tephritid genera is inferred from nucleotide sequences of subunit II of the mitochondrial cytochrome oxidase (COII) gene and the adjacent tRNALeu/COII intergenic region. Expand
Conditions for sympatric speciation: A diploid model incorporating habitat fidelity and non-habitat assortative mating
TLDR
A multilocus model in which genes of all three types of genes of sympatric speciation are considered simultaneously is described, showing that speciation occurs in complete sympatry under a broad range of conditions. Expand
