Sexual conflict as a constraint on asexual reproduction: an empirical review

open access: yesBiological Reviews, EarlyView.
ABSTRACT Theory predicts that facultatively asexual animals, which can leverage the advantages of both sexual and asexual reproduction, should outcompete obligately sexual and obligately asexual animals. Yet, paradoxically, obligate sexual reproduction predominates in many animal lineages, while the most flexible form of facultative asexuality (i.e ...

Conservation of Olfactory Avoidance in Drosophila Species and Identification of Repellents for Drosophila suzukii. [PDF]

open access: yes, 2015
Flying insects use olfaction to navigate towards fruits in complex odor environments with remarkable accuracy. Some fruits change odor profiles substantially during ripening and related species can prefer different stages.

Evaluation of different reference based annotation strategies using RNA-Seq - a case study in Drososphila pseudoobscura.

open access: yesPLoS ONE, 2012
RNA-Seq is a powerful tool for the annotation of genomes, in particular for the identification of isoforms and UTRs. Nevertheless, several software tools exist and no standard strategy to obtain a reliable annotation is yet established.

MicroRNA targets in Drosophila. [PDF]

open access: yes, 2003
BACKGROUND: The recent discoveries of microRNA (miRNA) genes and characterization of the first few target genes regulated by miRNAs in Caenorhabditis elegans and Drosophila melanogaster have set the stage for elucidation of a novel network of regulatory ...

Body size evolution as a catalyst for diversification of copulation strategies and its spillover effects on genital evolution and phylogenetic divergence in terrestrial arthropods

open access: yesPopulation Ecology, Volume 67, Issue 3, Page 191-207, July 2025.
A scenario in which divergent selection derived from ecological environments leads to genital divergence through body size evolution. Abstract To explore how ecological diversity contributes to the establishment of ecologically similar species with sexual divergence, this review focuses on body size—an environmentally influenced trait that determines ...

Chromosome-Level Assembly of Drosophila bifasciata Reveals Important Karyotypic Transition of the X Chromosome

open access: yesG3: Genes, Genomes, Genetics, 2020
The Drosophila obscura species group is one of the most studied clades of Drosophila and harbors multiple distinct karyotypes. Here we present a de novo genome assembly and annotation of D. bifasciata, a species which represents an important subgroup for

Principles of genome evolution in the Drosophila melanogaster species group. [PDF]

open access: yes, 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 ...

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.

Long‐Term Maintenance of Complex Chromosomal Inversion Polymorphism in Drosophila mediopunctata

open access: yesEcology and Evolution, Volume 14, Issue 10, October 2024.
It has become increasingly clear that natural selection favors haplotypes that draw functionally related genes together, often targeting mechanisms that control recombination rates. In this paper, we show that the long‐term maintenance of linkage disequilibrium between linked non‐overlapping chromosomal inversions in a Drosophila species may arise from
