How hot are drosophila hotspots? examining recombination rate variation and associations with nucleotide diversity, divergence, and maternal age in Drosophila pseudoobscura. [PDF]
PLoS ONE, 2013 Fine scale meiotic recombination maps have uncovered a large amount of variation in crossover rate across the genomes of many species, and such variation in mammalian and yeast genomes is concentrated to

G3: Genes, Genomes, Genetics, 2019 Meiotic crossing over ensures proper segregation of homologous chromosomes and generates genotypic diversity. Despite these functions, little is known about the genetic factors and population genetic forces involved in the evolution of recombination rate

Multifractal analysis of the long-range correlations in the cardiac dynamics of Drosophila melanogaster [PDF]
Chaos, Solitons and Fractals, vol. 28, p.p. 768-775 (2006), 2005 Time series of heartbeat activity of humans can exhibit long-range correlations. In this paper we show that such kind of correlations can exist for the heartbeat activity of much simpler species like Drosophila melanogaster. By means of the method of multifractal detrended fluctuation analysis (MFDFA) we calculate fractal spectra $f(\alpha)$ and $h(q)$

Principles of genome evolution in the Drosophila melanogaster species group. [PDF]
, 2007 That closely related species often differ by chromosomal inversions was discovered by Sturtevant and Plunkett in 1926. Our knowledge of how these inversions originate is still very limited, although a prevailing view is that they are facilitated by ...

Mating system manipulation and the evolution of sex-biased gene expression in Drosophila
Nature Communications, 2017 Sexual selection on males is thought to favour male-biased gene expression. Here, Veltsos et al. experimentally evolve Drosophila pseudoobscura under different mating systems and, contrary to expectation, most often find masculinization of the ...

Modeling ADHD in Drosophila: Investigating the Effects of Glucose on Dopamine Production Demonstrated by Locomotion [PDF]
arXiv, 2021 Hyperactivity is one of the hallmakrs of ADHD. Aberrant dopamine signaling is a major theme in ADHD and dopamine production is directly linked to the intensity and persistence of hyperactive conduct. The strength and persistence of hyperactivity responses in Drosophila to startle stimuli were measured in a study to determine the effects of sugar on ...

Genome-wide tests for introgression between cactophilic Drosophila implicate a role of inversions during speciation [PDF]
, 2015 K.L. was funded by a junior research fellowship from the National Environmental Research Council, UK (NE/I020288/1, NBAF659).Models of speciation-with-gene-flow have shown that the reduction in recombination between alternative chromosome arrangements ...

Complex Evolutionary History of the Y Chromosome in Flies of the Drosophila obscura Species Group. [PDF]
, 2020 The Drosophila obscura species group shows dramatic variation in karyotype, including transitions among sex chromosomes. Members of the affinis and pseudoobscura subgroups contain a neo-X chromosome (a fusion of the X with an autosome), and ancestral Y ...

Sex Bias and Maternal Contribution to Gene Expression Divergence in Drosophila Blastoderm Embryos. [PDF]
PLoS Genetics, 2015 Early embryogenesis is a unique developmental stage where genetic control of development is handed off from mother to zygote. Yet the contribution of this transition to the evolution of gene expression is poorly understood.

Genome of Drosophila suzukii, the spotted wing drosophila. [PDF]
, 2013 Drosophila suzukii Matsumura (spotted wing drosophila) has recently become a serious pest of a wide variety of fruit crops in the United States as well as in Europe, leading to substantial yearly crop losses.
