No evidence for learned mating discrimination in male
BMC Evolutionary Biology, 2006 Background Since females often pay a higher cost for heterospecific matings, mate discrimination and species recognition are driven primarily by female choice.

Intra-specific regulatory variation in Drosophila pseudoobscura.
PLoS ONE, 2013 It is generally accepted that gene regulation serves an important role in determining the phenotype. To shed light on the evolutionary forces operating on gene regulation, previous studies mainly focused on the expression differences between species and ...

Extensive divergence of transcription factor binding in Drosophila embryos with highly conserved gene expression. [PDF]
PLoS Genetics, 2013 To better characterize how variation in regulatory sequences drives divergence in gene expression, we undertook a systematic study of transcription factor binding and gene expression in blastoderm embryos of four species, which sample much of the ...

Age-dependent male mating investment in Drosophila pseudoobscura.
PLoS ONE, 2014 Male mating investment can strongly influence fitness gained from a mating. Yet, male mating investment often changes with age. Life history theory predicts that mating investment should increase with age, and males should become less discriminatory ...

Fly, 2021 Drosophila pseudoobscura is a classic model system for the study of evolutionary genetics and genomics. Given this long-standing interest, many genome sequences have accumulated for D. pseudoobscura and closely related species D. persimilis, D.

Zinc finger binding motifs do not explain recombination rate variation within or between species of Drosophila. [PDF]
PLoS ONE, 2012 In humans and mice, the Cys(2)His(2) zinc finger protein PRDM9 binds to a DNA sequence motif enriched in hotspots of recombination, possibly modifying nucleosomes, and recruiting recombination machinery to initiate Double Strand Breaks (DSBs).

In vivo RNAi rescue in Drosophila melanogaster with genomic transgenes from Drosophila pseudoobscura. [PDF]
PLoS ONE, 2010 BACKGROUND: Systematic, large-scale RNA interference (RNAi) approaches are very valuable to systematically investigate biological processes in cell culture or in tissues of organisms such as Drosophila.

Assessment of rival males through the use of multiple sensory cues in the fruitfly Drosophila pseudoobscura. [PDF]
PLoS ONE, 2015 Environments vary stochastically, and animals need to behave in ways that best fit the conditions in which they find themselves. The social environment is particularly variable, and responding appropriately to it can be vital for an animal's success ...

Sperm Predominance Among Drosophila pseudoobscura Karyotypes [PDF]
Evolution, 1984 Female Drosophila store sperm after mating and utilize them to fertilize eggs as they are laid. Often a female mates with a second male while sperm from the first mate still remain in her sperm storage organs. Parker (1970) defined sperm competition as the interaction between, and differential utilization of, sperm from separate ejaculates.
