CHARACTER DISPLACEMENT FOR SEXUAL ISOLATION BETWEEN DROSOPHILA MOJAVENSIS AND DROSOPHILA ARIZONENSIS
According to Brown and Wilson (1956) character displacement exists between two closely related species when their allopatric populations are very similar and their sympatric populations are quiteExpand

ASYMMETRICAL MATING PATTERNS BETWEEN GEOGRAPHIC STRAINS OF DROSOPHILA MERCATORUM: A TEST OF THE KANESHIRO HYPOTHESIS
Kaneshiro (1976) and Ohta (1978) observed asymmetrical behavioral isolation between species pairs of Hawaiian Drosophila whose phylogenetic relationships had previously been inferred from cytology,Expand

Cytogenetics of the South American DROSOPHILA MULLERI Complex: The MARTENSIS Cluster. More Interspecific Sharing of Inversions.
Three Drosophila mulleri complex species have been found to be endemic to the cactus regions of northern South America. The three species are morphologically distinct, and no hybridization betweenExpand

DOES ASYMMETRICAL MATING PREFERENCE SHOW THE DIRECTION OF EVOLUTION?
The analysis of present behavior patterns is often a useful tool in our attempts to decipher the past. Studies of reproductive behavior have proven particularly fruitful in this regard, for theExpand

  • 1 November 1987
The situation in which behavioral differences prevent interspecific mating has been called sexual isolation (Dobzhansky, 1970). Although examples of this phenomenon abound, many questions concerningExpand

A Simpler Sieving Device: Combining ECM and TWIRL
TLDR
We describe a device building on the Elliptic Curve Method (ECM) that for parameters of interest enables the replacement of the complete logging part in TWIRL by an off-wafer postprocessing. Expand

Phylogenetic Relationships among DROSOPHILA LONGICORNIS, DROSOPHILA PROPACHUCA and DROSOPHILA PACHUCA, a Triad of Sibling Species.
Drosophila longicornis, D. propachuca and D. pachuca comprise a triad of sibling species. They are morphologically indistinguishable, sympatric forms that, under laboratory conditions, are capable ofExpand

Developmental isolation and subsequent adult behavior ofDrosophila paulistorum. I. Survey of the six semispecies
We present results deriving from the inception of an investigation (involving 4,000 scored matings) into the development of discriminatory behavior inDrosophila paulistorum. We examined twoExpand

Fitness of karyotypes in Drosophila pseudoobscura.
In the dynamics of the survival of chromosomal polymorphism selection may be operating at the genic level, at the chromosomal level or at the supergene level. Tests designed to distinguish betweenExpand
