Proceedings of the National Academy of Sciences (PNAS), a peer reviewed journal of the National Academy of Sciences (NAS) - an authoritative source of high-impact, original research that broadly spans...

Sex ratio distorters (SRDs) are heritable elements that bias offspring sex ratios to enhance their transmission. In the terrestrial isopod Armadillidium vulgare, feminization of genetic males can occu...

Top predators drive changes in ecosystem structure. For the last ~370 million years, large-sized vertebrates have dominated the apex of the marine food chain, while invertebrates have served as smalle...

Many bacterial taxa evolved facultative symbiotic associations with insects and spread through host populations by horizontal and maternal transmission. Co-infection at the individual host level may ...

We investigated maternal effects in Schizotetranychus brevisetosus (Tetranychidae), where females oviposit summer and winter eggs in response to photoperiod on evergreen hosts. Developmental rates o...

Herbivorous insects can shape the epidemiology of disease in plants by vectoring numerous phytopathogens. While the consequences of infection are often well-characterized in the host plant, the extent...

Certain genes, chromosomes, organelles, or entire sets of chromosomes can bias their transmission to the next generation, propagating themselves at the expense of the rest of the genome. Referred to …

The pillbug Armadillidium vulgare is a common isopod generalist decomposer in most natural landscapes. Past European and US studies have looked at the genetic diversity and frequency of A. vulgare and...

npj Aging - Age, caste, and social context shape ovarian morphology and transcriptomic profiles in red harvester ants

The release of Aedes aegypti mosquitoes transinfected with the virus-inhibiting Wolbachia bacterium has the potential to reduce the burden caused by dengue virus (DENV). However, the robustness of thi...

Ant queens of one species clone ants of another to create hybrid workers that do their bidding.

Maternally transmitted symbionts such as Wolbachia spread within host populations by mediating reproductive phenotypes. Cytoplasmic incompatibility (CI) is a reproductive phenotype that interferes wi...

Male-killing bacterial symbionts, prevalent in arthropods, skew population sex ratios by selectively killing male progeny, profoundly impacting ecolog…
