The spontaneous mutation rate of Drosophila pseudoobscura [PDF]
G3: Genes, Genomes, Genetics, 2021 The spontaneous mutation rate is a very variable trait that is subject to drift, selection and is sometimes highly plastic. Consequently, its variation between close species, or even between populations from the same species, can be very large.

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 ...

Intra-specific regulatory variation in Drosophila pseudoobscura. [PDF]
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 ...

Age-dependent male mating investment in Drosophila pseudoobscura. [PDF]
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 ...

Extensive exchange of transposable elements in the Drosophila pseudoobscura group [PDF]
Mobile DNA, 2018 Background As species diverge, so does their transposable element (TE) content. Within a genome, TE families may eventually become dormant due to host-silencing mechanisms, natural selection and the accumulation of inactive copies.

A history of studies of reproductive isolation between Drosophila pseudoobscura and D. persimilis [PDF]
FlyDrosophila pseudoobscura and D. persimilis are a sister species pair that have been used as a model for studies of reproductive isolation and speciation for almost 100 years owing to their close evolutionary history, well characterized genetic ...

Evidence that Natural Selection on Codon Usage inDrosophila pseudoobscuraVaries Across Codons [PDF]
G3: Genes, Genomes, Genetics, 2014 Like other species of Drosophila, Drosophila pseudoobscura has a distinct bias toward the usage of C- and G-ending codons. Previous studies have indicated that this bias is due, at least in part, to natural selection.

PseudoBase: a genomic visualization and exploration resource for the Drosophila pseudoobscura subgroup [PDF]
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.

Extensive Recombination Suppression and Epistatic Selection Causes Chromosome-Wide Differentiation of a Selfish Sex Chromosome in Drosophila pseudoobscura. [PDF]
Genetics, 2020 The Drosophila pseudoobscura Sex-Ratio (SR) chromosome was one of the first-discovered segregation distorter chromosomes. Despite being a historically significant and well-studied segregation distortion system, the mechanisms allowing for the long-term...

An X-linked meiotic drive allele has strong, recessive fitness costs in female <i>Drosophila pseudoobscura</i>. [PDF]
Proc Biol Sci, 2019 Selfish ‘meiotic drive’ alleles are transmitted to more than 50% of offspring, allowing them to rapidly invade populations even if they reduce the fitness of individuals carrying them.
