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 ...

Mating system variation drives rapid evolution of the female transcriptome in Drosophila pseudoobscura. [PDF]
Ecol Evol, 2014 Interactions between the sexes are believed to be a potent source of selection on sex-specific evolution. The way in which sexual interactions influence male investment is much studied, but effects on females are more poorly understood.

The spontaneous mutation rate of Drosophila pseudoobscura. [PDF]
G3 (Bethesda), 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.

Evidence for stabilizing selection on codon usage in chromosomal rearrangements of Drosophila pseudoobscura. [PDF]
G3 (Bethesda), 2014 There has been a renewed interest in investigating the role of stabilizing selection acting on genome-wide traits such as codon usage bias. Codon bias, when synonymous codons are used at unequal frequencies, occurs in a wide variety of taxa.

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 ...

Opposite environmental and genetic influences on body size in North American Drosophila pseudoobscura. [PDF]
BMC Evol Biol, 2015 BACKGROUND: 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 are instead simply a plastic response to ...

Ancestral polymorphisms inDrosophila pseudoobscuraandDrosophila miranda [PDF]
Genetics Research, 2011 Ancestral polymorphisms are defined as variants that arose by mutation prior to the speciation event that generated the species in which they segregate. Their presence may complicate the interpretation of molecular data and lead to incorrect phylogenetic

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 Drosophila pseudoobscura. [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.

How chromosomal rearrangements shape adaptation and speciation: Case studies in Drosophila pseudoobscura and its sibling species Drosophila persimilis. [PDF]
Mol Ecol, 2019 The gene arrangements of Drosophila have played a prominent role in the history of evolutionary biology from the original quantification of genetic diversity to current studies of the mechanisms for the origin and establishment of new inversion mutations
