Plant phenology is often involved in local adaptation. Genetic variation in phenology of Eurasian #Arabidopsis predicted continental patterns of natural #phenology. But locally, within regions, phenology of Arabidopsis individuals has low #heritability: doi.org/10.1093/jeb/... DeLeo et al.

NEW METHODS ARTICLE: Phylogenetic GLMMs open doors to study evolution of discrete traits. We show how binary models extend to ordinal & nominal traits, using bird data, and provide tutorials to make these methods accessible to evolutionary biologists: doi.org/10.1093/jeb/... Mizuno et al.

It’s time to publish responsibly! (And has been for a while, quite frankly...) To help you do so, @nicolasgaltier.bsky.social and coauthors have put together a handy database of academia-friendly journals, DAFNEE. You can read about it in their article just out in @jevbio.bsky.social.

Delighted to publish Forum Article by @nicolasgaltier.bsky.social et al: "Journals run by learned societies or universities have more ethical policies while being cheaper and similarly cited" doi.org/10.1093/jeb/... Thank you for choosing JEB - we encourage the support of #societyjournals

Our paper in a great journal!

For cannibalistic #dragonfly larvae, chemical cues from conspecifics can signal either danger or dinner, shifting behavior from self-defense to foraging. This causes nonlinear, density-dependent effects on heterospecific prey: Sysiak et al.: doi.org/10.1093/jeb/...

Some pheromones are costly. Female moths use long distance pheromones to attract mates, with different blends of chemicals to indicate their species. #Moths producing higher amounts of acetates took longer to reach adulthood and produced fewer eggs per day: Fruitet et al.: doi.org/10.1093/jeb/...

Sea #otters have undergone distinctive evolutionary changes in the offspring size–number trade-off within the #Mustelidae. The changes involve larger and fewer offspring and more investment in offspring size than expected: doi.org/10.1093/jeb/... Harano and Kutsukake 2025

Two chloroplast haplogroups are found in Quercus suber with selection detected in chloroplast codon sites. Polymorphism is segregated between the two haplogroups, suggesting that balancing selection preserves them: doi.org/10.1093/jeb/... de Sousa et al. 2025 @octaviospaulo.bsky.social

By combining mark-recapture and genetic parentage data from wild #lizards, we show that the offspring of older parents do not have lower survival or reproductive success than the offspring of younger parents: doi.org/10.1093/jeb/... Crain 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

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

Major histocompatibility complex (MHC) modulation of Batrachochytrium dendrobatidis and Ranavirus infections in amphibians: doi.org/10.1093/jeb/... Cortazar-Chinarro 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
