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.

Opposite environmental and genetic influences on body size in North American Drosophila pseudoobscura. [PDF]
BMC Evol Biol, 2015 Journal ArticleResearch Support, Non-U.S. Gov'tBACKGROUND: Populations of a species often differ in key traits. However, it is rarely known whether these differences are associated with genetic variation and evolved differences between populations, or ...

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.

Can patterns of chromosome inversions in Drosophila pseudoobscura predict polyandry across a geographical cline? [PDF]
Ecology and Evolution, 2014 Journal ArticleFemale multiple mating, known as polyandry, is ubiquitous and occurs in a wide variety of taxa. Polyandry varies greatly from species in which females mate with one or two males in their lifetime to species in which females may mate with ...

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.
