Range edge populations often face novel conditions. Across the range of Mimulus cardinalis, we found trailing-edge populations have the most flowering-time plasticity. Plasticity evolved after extreme drought, though adaptive benefits varied by trait: doi.org/10.1093/jeb/... Cook et al. 2026

Males and females of the dioecious annual herb Mercurialis annua are more likely to show ‘leaky’ or inconstant sex expression and higher reproductive effort towards the range margin: doi.org/10.1093/jeb/... Nguyen and Pannell 2026

Selfish genetic elements (SGEs) attempt to manipulate inheritance to enhance their own transmission. But when a host contains two or more SGEs, how might they interact? We expand on ideas about how various kinds of SGE may interact within a genome: doi.org/10.1093/jeb/... Wilson and Wedell 2026

Inversions on chromosomes 2 and 12 might assist with acute high-temperature and low-salinity adaptation, respectively, in cod eggs: doi.org/10.1093/jeb/... @discoverunb.bsky.social

By tracking tumor development across organs in wild-derived mice throughout life, we show that tumors emerge late under controlled conditions and that heterozygosity appears protective, offering new insights into how genetics and aging shape cancer risk: Bernex et al. 2026 doi.org/10.1093/jeb/...

Temporal mapping of tumor development in mice reveals late onset and benefits of heterozygosity

Abstract. Despite decades of cancer research, the stage of life at which cancerous processes lead to tumor formation in various organs remains poorly under

Chromosomal inversions are both engines of repeatability and innovation. They drive parallel genetic divergence between snail ecotypes across Europe, while also harbouring local variants that contribute to site-specific trait variations and adaptation: doi.org/10.1093/jeb/... Pajot et al 2026

Inversions support both parallel and location-specific adaptations in snail ecotypes

Abstract. Replicated hybrid zones between ecotypes established over environmental gradients provide an opportunity to study the genomic architecture of bar

When should parasites manipulate their hosts specifically toward the right predator? New model in @jevbio.bsky.social shows it’s the cost of specificity — not the intensity of dead-end predation — that determines whether precise manipulation evolves: doi.org/10.1093/jeb/... Seppälä 2026

Can selfish genetic elements get away with their selfishness? This depends on ecology of their host organisms. Under certain conditions, selfish genetic elements may spread virtually unopposed by selection: doi.org/10.1093/jeb/... @martijnschenkel.bsky.social @arvidagren.bsky.social & M. Patten

Megaraptorid dinosaurs evolved enormous hand claws instead of relying mainly on their heads for hunting. These claws became larger and changed shape into a specialised predatory tool that remained stable and highly specialised for millions of years: Pereyra & Ibiricu 2026 doi.org/10.1093/jeb/...

@andygardner.bsky.social shows that internal conflict per se does not erode an individual’s adaptive integrity. Instead, it is variation in the balance of power between genetic factions across different traits that drives the breakdown of the unity of purpose: doi.org/10.1093/jeb/...

Inclusive fitness for the conflicted individual

Abstract. The theory of inclusive fitness explains the process and purpose of social adaptation. However, the canonical derivation of inclusive fitness ass
