| genetics of divergence in male wing pigmentation and courtship behavior between drosophila elegans and d. gunungcola. | many sex-specific traits involved in mating consist of functionally coordinated morphologies and behaviors. how the components of these complex traits evolve and become coordinated during evolution is unknown. in order to understand how such trait complexes evolve and diversify, we must decipher the genetic underpinnings of their components. in this study, we begin to elucidate the genetic architecture underlying differences in functionally related male pigmentation and behavior between two asia ... | 2006 | 16570069 |
| an intron loss of dfak gene in species of the drosophila melanogaster subgroup and phylogenetic analysis. | drosophila focal adhesion kinase (dfak) gene is a single-copy nuclear gene. previous study revealed that drosophila melanogaster and drosophila simulans had lost an intron precisely within the tyrosine kinase (tyk) domain of this gene. however, this did not happen in several other drosophila species, including drosophila elegans, drosophila ficusphila, drosophila biarmipes, drosophila jambulina, drosophila prostipennis, drosophila takahashii, and drosophila pseudoobscura. in the current study, h ... | 2009 | 18310070 |
| the genetic architecture of coordinately evolving male wing pigmentation and courtship behavior in drosophila elegans and drosophila gunungcola. | many adaptive phenotypes consist of combinations of simpler traits that act synergistically, such as morphological traits and the behaviors that use those traits. genetic correlations between components of such combinatorial traits, in the form of pleiotropic or tightly linked genes, can in principle promote the evolution and maintenance of these traits. in the oriental drosophila melanogaster species group, male wing pigmentation shows phylogenetic correlations with male courtship behavior; spe ... | 2014 | 25168010 |
| sexual isolation and cuticular hydrocarbons in drosophila elegans. | in drosophila elegans, partial sexual isolation has developed between the brown and black morphs, which are distributed allopatrically. the present study aims to understand how they discriminate between potential mates. mating experiments show that the females of the two morphs differ in sexual signal(s) and the males discriminate using these differences. body colouration is not used as a sexual cue in this species. between the females of the two morphs, a large difference was observed in the pe ... | 2001 | 11737286 |
| mate discrimination and cuticular hydrocarbons in drosophila elegans and d. gunungcola. | in drosophila elegans, two morphs are known, the brown-morph occurring from southern china to indonesia and the black-morph occurring in the ryukyu islands, japan, and taiwan, and brown-morph populations at high altitudes in indonesia at least sympatrically occur with a sibling species d. gunungcola. sexual isolation has developed between the two morphs of d. elegans to some extent; females of the black-morph have a higher concentration of pentacosenes on cuticle than those of the brown-morph, a ... | 2002 | 12426482 |
