The transformer gene controls sexual development in Drosophila suzukii

open access: yesInsect Science, EarlyView.
The transformer gene plays a key role in the genetic pathway for sexual development in Drosophila suzukii Abstract The genetic network of sex determination in the model organism Drosophila melanogaster was investigated in great detail. Such knowledge not only advances our understanding of the evolution and regulation of sexual dimorphism in insects ...

Sperm Transfer Under Behavioral and Morphological Constraints in the Orb‐Web Spider Genus Argiope

open access: yesIntegrative Zoology, EarlyView.
The polygamous mating system of the orb‐web spider genus Argiope provides a model to study the evolution of sperm transfer under morphological and behavioral constraints. This helps us to understand how male and female behavioral and morphological reproductive traits influence sperm transfer.

The influence of chromosomal inversions on genetic variation and clinal patterns in genomic data of Drosophila melanogaster [PDF]

open access: yesarXiv
Chromosomal inversions are structural mutations resulting in the reversal of the gene order along the corresponding genomic region. Due to their influence on recombination patterns, they can have a major influence on genetic variation and the evolutionary process.

The onset of homologous chromosome pairing during Drosophila melanogaster embryogenesis. [PDF]

open access: yes, 1993
We have determined the position within the nucleus of homologous sites of the histone gene cluster in Drosophila melanogaster using in situ hybridization and high-resolution, three-dimensional wide field fluorescence microscopy.

UV‐Induced Fluorescence in the Balance: Mate Choice and Predation Risk in the Female Ornamented Jumping Spiders

open access: yesIntegrative Zoology, EarlyView.
This study investigates the potential adaptive advantages of female‐specific UV‐induced fluorescence in male mate‐choice and predation risk, as fitness costs, using two species of ornate jumping spiders Phintella vittata and Ph. bifurcilinea. Our findings provide empirical evidence of a trade‐off: While fluorescence enhances male mate preference, it ...

Polytene chromosomes as indicators of phylogeny in several species groups of Drosophila. [PDF]

open access: yes, 2001
BackgroundPolytene chromosome banding patterns have long been used by Drosophila evolutionists to infer degree of relatedness among taxa. Recently, nucleotide sequences have preempted this traditional method.
