Physiological Entomology, EarlyView.Most Drosophila species, such as D. melanogaster, make one type of sperm, while the obscura species group produces multiple sperm morphs, with different total lengths and nuclear lengths. The pseudoobscura species subgroup produces three sperm morphs (one long, two short). This is a derived feature as other sub‐groups produce two sperm morphs.

PLoS 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.

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 ...

Sexual conflict as a constraint on asexual reproduction: an empirical review
Biological Reviews, Volume 100, Issue 6, Page 2681-2706, December 2025.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 ...

Functional Evolution of cis-Regulatory Modules at a Homeotic Gene in Drosophila [PDF]
, 2011 It is a long-held belief in evolutionary biology that the rate of molecular evolution for a given DNA sequence is inversely related to the level of functional constraint.

Determinants of mating success in a lek‐mating species
Agricultural 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,

G3: 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

Ecology 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 ...

Drosophila Sexual Attractiveness in Older Males Is Mediated by Their Microbiota
Microorganisms, 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.
