Do you like your learned society and what it does for you and your research community? Then publish in their journal! This paper by @nicolasgaltier.bsky.social & Co shows that it will only do good, and comes with a handy database of academy-friendly journals. 👇

NEW PAPER with @arvidagren.bsky.social and Manus Patten on evolutionary reversions in individuality now out (as an advance article) at @jevbio.bsky.social (see academic.oup.com/jeb/advance-...). Thread below! [1/8] .

Responsible publication of your research! To help you do this @nicolasgaltier.bsky.social and coauthors have put together a handy database of academia-friendly journals, DAFNEE. You can read about it in their article recently published in @jevbio.bsky.social: doi.org/10.1093/jeb/...

During directional selection, advantageous trait values tend to become associated with earlier reproduction, accelerating the evolutionary response of the trait mean. This can lead to directional change even after selection has stopped: Mitteroecker (2025) doi.org/10.1093/jeb/...

Comparative studies on genetic differentiation between two closely related species of #Drosophila; D. bipectinata and D. malerkotliana: Singh et al. (2025) doi.org/10.1093/jeb/...

Are Darwin's finches affected by climate change? Time-series analyses of beak and body traits, precipitation and temperature show finches are a resilient system, responding mainly to short-term weather variation rather than to long-term climate change: Carrión et al. (2025) doi.org/10.1093/jeb/...

Some Hawaiian cricket populations are losing the ability to sing. Males on Oahu invest more in sperm competition than males on Kauai by making more sperm and packing more proteins to increase sperm viability and slow female remating: @jessiectanner.bsky.social et al. (2025) doi.org/10.1093/jeb/...

📢Out now in @jevbio.bsky.social, we tried to work out whether heat limits of survival or fertility are reflected in heat shock protein expression across Drosophila 🪰 species. The answer is, well, a bit. With the wonderful @chsmithson.bsky.social @ejduncan.bsky.social doi.org/10.1093/jeb/...

Just a week left to apply for a position in our Editorial Board!

@kztwyman.bsky.social & @andygardner.bsky.social mathematically connect the dynamics of natural selection to optimisation to provide formal justification for viewing obligately eusocial colonies as adaptive individuals in their own right—that is, superorganism: doi.org/10.1093/jeb/...

CALL OPEN NOW - Would you like to join the JEB Editorial Board? 📣 Deadline for applications - Monday 19th January 📣 We'd love to receive applications from across the field of evolutionary biology!

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.

Carpenter #ants possess symbiotic #bacteria that are evolving in high-altitude forests! Our sequenced endosymbionts from CA’s Sierra Nevada Mts reveal their gene losses & adaptations to montane life. #Evolution #Genomics. doi.org/10.1093/jeb/... Maynard et al @uofcalifornia.bsky.social

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
