Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)

Insect Science, EarlyView.
As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...

Krüppel Expression Levels Are Maintained through Compensatory Evolution of Shadow Enhancers

Cell Reports, 2015
Many developmental genes are controlled by shadow enhancers—pairs of enhancers that drive overlapping expression patterns. We hypothesized that compensatory evolution can maintain the total expression of a gene, while individual shadow enhancers diverge ...

Recombination suppression in plant adaptation and speciation

New Phytologist, Volume 250, Issue 4, Page 2061-2077, May 2026.
Summary Recombination suppression is increasingly recognized as an important facilitator of genomic divergence and speciation, especially under ongoing gene flow. In plants, however, the broader evolutionary consequences and the mechanisms by which recombination suppression arises and spreads are still incompletely understood, reflecting the inherent ...

Clustering sperm: A statistical approach to identify sperm morph numbers in the Drosophila obscura species group

Physiological Entomology, Volume 51, Issue 1, Page 48-62, March 2026.
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.

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

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.

A Set of Novel Venom Proteins Enables Parasitoid Wasps to Exploit Older Hosts and Coexist with Competitors

Advanced Science, Volume 13, Issue 4, 19 January 2026.
This study elucidates a molecular mechanism enabling species coexistence between parasitoid wasps, showing how Asobara japonica uses a set of novel venom proteins to delay host development and exploit older hosts, thereby achieving temporal niche partitioning with Leptopilina drosophilae. Abstract Interspecific competition can drive species coexistence

Conserved genomic organisation of Group B Sox genes in insects.

BMC Genetics, 2005
Background Sox domain containing genes are important metazoan transcriptional regulators implicated in a wide rage of developmental processes. The vertebrate B subgroup contains the Sox1, Sox2 and Sox3 genes that have early functions in neural ...

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

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

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 ...
