Fighter ant males show canalized weapon development but extreme variation in other morphological traits, highlighting how #sexualselection shapes #phenotypicevolution: doi.org/10.1093/jeb/... Neupert et al @uniregensburg.bsky.social

How to use and interpret the #adaptationinertia framework of #phylogenetic comparative methods based on the Ornstein-Uhlenbeck process to study adaptation: doi.org/10.1093/jeb/... Pienaar et al. 2025

In some species, #mitochondria have lost functions: from specific complexes to the ability to produce #ATP (and more!). We examine the evolutionary pathways of this reduction, from yeast and mistletoe to parasite "MROs": doi.org/10.1093/jeb/... @mitomaths.bsky.social et al. 2025

A #transcriptomic study shows that single nucleotide polymorphisms in #6Pgdh - a metabolic gene involved in #sexualselection and conflict in bulb mite, Rhizoglyphus robini - can be associated with genome wide gene expression differences: doi.org/10.1093/jeb/... Plesnar-Bielak et al. 2025

The genetic basis of #flight capacity is more strongly linked to nervous system processes than to #wingmorphology: doi.org/10.1093/jeb/... Flaibani et al. #Evolution Lab (IEGEBA-CONICET) #drosophila

Using phylogenetically informed sampling of 98 genera, we show that reductions of the ant stinging apparatus are associated with shifts in diet and foraging facilitating ecological transitions and diversification: doi.org/10.1093/jeb/... Casadei-Ferreira et al. 2025

The genetical evolution of social preferences: where the categorical imperatives of Hamilton, Kant, and Nash meet: doi.org/10.1093/jeb/...

A Kronholm Lab evolution experiment with #yeast reveals that constant high temperature imposes a stronger #selection pressure than fluctuating temperatures, and that population size does not seem to influence #fitness #trade-offs: doi.org/10.1093/jeb/... Räsänen et al. 2025

Why do single-celled organisms commit suicide? Our latest research reveals that it is not a mystery, but a form of cooperation. Programmed cell death (PCD) can strengthen endosymbiosis between host and symbiont, thereby helping clones: doi.org/10.1093/jeb/... Sathe and Becks 2025

Combining genomic and neuroanatomical data shows that #Heliconiini olfactory systems vary in their #olfactory receptor diversity and investment in individual brain structures, but are developmentally plastic in responsive to environmental conditions: doi.org/10.1093/jeb/... Yi Peng et al. 2025

Tropical rainforest #fruitflies show limited capacity for remating, even though successive matings do not reduce offspring quality: doi.org/10.1093/jeb/... Saxon et al. 2025

Dumas et al. used long-term data on Alpine #swifts, traditionally described as monomorphic, to test for temporal changes in sexual dimorphism (SD) and allometry. They found small but persistent SD, temporal changes in SD, and negative allometric scaling in both sexes: doi.org/10.1093/jeb/...

How do multidimensionally selected traits respond to rapid change? Our study shows the importance of examining #plasticity under complex environmental contexts and suggests a role of social dynamics in the development of trait diversity in nature: doi.org/10.1093/jeb/... Puleo et al. 2025

Simple maternal effect animal models may provide biased estimates of additive genetic and maternal variation: doi.org/10.1093/jeb/... @joelpick.bsky.social et al. 2025

Sperm length varies enormously, with some sperm longer than the males that produce them. Understanding this variation often requires controlling for mean sperm length, but based on our assessment, the current methods used for this are often wrong: doi.org/10.1093/jeb/... Hosken et al. 2025

@romanzug.bsky.social and @socialinsectlab.bsky.social thinking about colony dynamics! Resource variation can mask tradeoffs, but here we show that even if that *doesn't* vary, lucky starts in colony life can lead to better trajectories and if so, a tradeoff is often undetectable despite being real.

Mesocosm experiments and lab-based digestive assays reveal that selection on digestive physiology can buffer organisms against putative costs of predator avoidance, demonstrating how trait networks can decouple growth from predation risk in complex ecological systems: doi.org/10.1093/jeb/...

How do light and noise pollution impact selection on sexual signals? We tested mate attraction and bat predation on túngara frogs. Light and noise interact in complex ways, and light pollution shifts selection on male calling: doi.org/10.1093/jeb/... @andrewdcronin.bsky.social et al.

Ribeiro et al. studied #MHC class II variation and infection by a sexually transmitted bacterium (C34) in black-legged #kittiwakes. They found sex-specific links between MHC supertypes, bacterial load and reproduction, suggesting STIs may influence immune gene evolution: doi.org/10.1093/jeb/...

Let’s talk about sperm. Almost all passerine birds have filiform sperm with corkscrew-shaped heads. Not the red-browed finch. This species has highly atypical sperm morphology. Check it out!

Editor’s choice 😎 and it‘s a short read 😉. We show evidence of de novo genes emerging from the Nucleosome Depleted Regions (NDRs) of yeast genomes. They are biased towards encoding transmembrane domains because of the NDRs too!
