Frogs and toads have very diverse skin. 3D surface profilometry shows frog skin texture varies across body regions and microhabitats. Ventral “drink patches” tend to be rougher, but evolutionary rates similar across the body: doi.org/10.1093/jeb/... Urgiles et al. 2026 @mollycwomack.bsky.social

Warts and all: evolutionary and ecological patterns in frog skin textureAbstract. The external appearance of frog skin varies among species and across body regions. Although this variation has long been recognized, it remains adoi.org

New research in red flour beetles shows that sexual conflict is condition-dependent: high-condition males inflict more harm, while high-condition females resist it better. Findings reveal sex differences in adaptation may shape evolutionary outcomes: doi.org/10.1093/jeb/... Gómez-Llano 2026

Individual condition mediates the costs of sexual conflict through both male harm and female resistanceAbstract. Sexual conflict arises when the reproductive interests of males and females diverge, leading to decreased female fitness due to male‐induced harmdoi.org

Female ornamentation may evolve through sexual/social selection, but does dispersal or breeding density affect it? Using 34 yrs of #piedflycatcher data, we find out: Redondo et al. 2026 doi.org/10.1093/jeb/...

Absence of dispersal-mediated selection on the expression of a female ornament—a long-term study in a wild bird populationAbstract. There is increasing evidence that female ornamentation is not merely a genetic by-product of male ornamentation and has evolved through sexual andoi.org

In Coffea, larger genomes occur in equatorial lowland species, but phylogenetic analyses reveal no association between genome size and environment. We show how singular events and historical contingencies can shape evolutionary trajectories: Gonçalves Barbosa et al. 2026 doi.org/10.1093/jeb/...

Historical shifts and ecological patterns: rethinking genome size evolution in Coffea LAbstract. Although genome size (GS) is decoupled from organismal complexity, a phenomenon known as the C-value paradox, some authors have proposed that GSdoi.org

In #zebrafinches, telomere shortening - not absolute telomere length - best predicts lifespan, with the strongest effect seen among the longer telomeres in the distribution: @mtangili.bsky.social @gelifes.bsky.social doi.org/10.1093/jeb/...

Telomere dynamics, not absolute telomere length, predicts lifespan in adult zebra finchesAbstract. Telomeres shorten with age, and telomere length (TL) can predict lifespan. In vitro studies have established that the shortest telomeres in the gdoi.org

Our study shows that mutation-rate differences between daughter DNA strands persist throughout evolution rather than converging to equal fidelity. Evolution maintains asymmetric replication fidelity through self-organisation of mutation rates: doi.org/10.1093/jeb/... Akashi and Furusawa 2026

Replication fidelity difference between daughter chains persists during evolutionAbstract. While mutations are the engine of evolution, how mutation rates themselves evolve remains poorly understood. Previous simulation and experimentaldoi.org

How well can species adapt to rapid climate change? We introduce space-for-time substitution, including reciprocal gut-microbiome transplants, showing warm-adapted microbes can protect cold-adapted damselfly from immune suppression under future warming: doi.org/10.1093/jeb/... Theys et al. 2026

Extending space-for-time substitutions: the missing role of the gut microbiomeAbstract. The space-for-time substitution (SFTS) approach is widely used to predict evolutionary trait responses to global warming. The current approach igdoi.org

How do parasites adapt to multiple hosts with a single genome? This study supports the adaptive decoupling hypothesis and help explain how complex multi-host life cycles evolve. Laura Gramolini et al. @humboldtuni.bsky.social @igb-berlin.de doi.org/10.1093/jeb/...

In most social insects queen loss triggers worker reproduction & physiological change. In Lasius neglectus: sterile workers never lose their queens, invasiveness has reshaped the division of labour: Major et al: doi.org/10.1093/jeb/...
