Recombination modulates how selection affects linked sites in Drosophila

, 2012
One of the most influential observations in molecular evolution has been a strong association between regional recombination rate and amount of nucleotide polymorphism in those genomic regions, interpreted as evidence for ubiquitous natural selection ...

Population Genomics of Sub-Saharan Drosophila melanogaster: African Diversity and Non-African Admixture [PDF]

, 2012
Drosophila melanogaster has played a pivotal role in the development of modern population genetics. However, many basic questions regarding the demographic and adaptive history of this species remain unresolved.

Strong founder effect in Drosophila pseudoobscura colonizing New Zealand from North America

, 2002
The North American native species Drosophila pseudoobscura was first identified in New Zealand in the last few decades. Here, we have studied the genetic consequences of its spread across the Pacific Ocean.

Titin Is Present in the Elastic Tethers That Connect Separating Anaphase Chromosomes in Crane‐Fly Spermatocytes

Cytoskeleton, EarlyView.
ABSTRACT Elastic tethers connect telomeres of separating chromosomes in anaphase of animal cells. Immunofluorescence staining of titin in crane‐fly spermatocytes, using 4 different antibodies, shows that the giant elastic protein titin seems to be a component of mitotic tethers: titin “strands” extend between separating chromosomes, connecting their ...

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

Insect Science, Volume 33, Issue 3, Page 1109-1122, June 2026.
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 ...

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.

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
