The heritability of mating behaviour in a fly and its plasticity in response to the threat of sperm competition.

open access: yesPLoS ONE, 2014
Phenotypic plasticity is a key mechanism by which animals can cope with rapidly changeable environments, but the evolutionary lability of such plasticity remains unclear.

Drosophila Sexual Attractiveness in Older Males Is Mediated by Their Microbiota

open access: yesMicroorganisms, 2020
Age is well known to be a basis for female preference of males. However, the mechanisms underlying age-based choices are not well understood, with several competing theories and little consensus.

Determinants of mating success in a lek‐mating species

open access: yesAgricultural and Forest Entomology, Volume 27, Issue 4, Page 643-652, November 2025.
Abstract Leks are male‐biased aggregations formed for mating, where sperm is the only resource acquired by visiting females. One of the many advantages of leks is the possibility to efficiently assess the quality of potential mates by comparing aggregated individuals of the same sex with one another. When direct mate choice occurs in a lekking species,

Preadult competition between Drosophila subobscura and Drosophila pseudoobscura

open access: yesJournal of Zoological Systematics and Evolutionary Research, 2009
The Palaearctic species Drosophila subobscura has recently colonized a large area of North America where it coexists with Drosophila pseudoobscura. The viability and developmental rate of these species were studied at 13 dC, 18dC and 23 dC and at densities of 10, 50, 100 and 200 eggs per vial.

PATTERN OF CHROMOSOME VARIABILITY IN DROSOPHILA PSEUDOOBSCURA [PDF]

open access: yesEvolution, 1960
It has been noted by several investigators (Dobzhansky 1944; Novitski 1946; Pavan 1946) that in some species of Drosophila, variability in chromosome structure is virtually restricted to one chromosome. At the same time, they note, the variable chromosome has a large number of inversions distributed throughout the species. This paper shall be addressed

Transcriptomic Analysis and Comparative Analysis of Gene Families Related to Environmental Adaptation in Two Grylloblattodea Species: Galloisiana sinensis and Grylloprimevala jilina

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
Notoptera, a singular ancient insect lineage, is vital for exploring insect environmental adaptation, evolution, and its geological history link, recognized as a national first‐class protected animal. Comparing environmental adaptation genes in Galloisiana sinensis and Grylloprimevala jilina, closely related yet habitat‐disparate species, illuminates ...

Extensive divergence of transcription factor binding in Drosophila embryos with highly conserved gene expression. [PDF]

open access: yesPLoS 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 ...

Evolution of Phospholipase A2 in Bees and Flies

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
This study investigated the evolution of the PLA2 gene in bees and flies and compared the evolutionary rate between them, which denotes the toxic group and the non‐toxic group. The results showed that PLA2 was under purifying selection and that an accelerated evolution of PLA2 occurred in the toxic group when compared with the non‐toxic group ...

Epistasis among Drosophila persimilis factors conferring hybrid male sterility with D. pseudoobscura bogotana. [PDF]

open access: yesPLoS ONE, 2010
The Bateson-Dobzhansky-Muller model posits that hybrid incompatibilities result from genetic changes that accumulate during population divergence.

RepeatOBserver: Tandem Repeat Visualisation and Putative Centromere Detection

open access: yesMolecular Ecology Resources, Volume 25, Issue 7, October 2025.
ABSTRACT Tandem repeats play an important role in centromere structure, subtelomeric regions, DNA methylation, recombination and the regulation of gene activity. Analysis of their distribution in genomes offers a potential means for predicting putative centromere locations, which continues to be a challenge for genome annotation.
