Cover ImageCover: It may appear as if two ant colonies are engaged in battle, but all of the ants pictured on the cover are sisters. In this species, Harpegnathos saltator, workers compete in elaborate dominance tournaments to determine a reproductive hierarchy. Penick et al. (pp. 1496−1503) show that during these tournaments, dopamine levels link reproductive status with changes in the brain associated with dominance position. The worker at the center (marked with paint) is policed by her sisters, which causes her dopamine levels to rapidly decline along with her dominance standing. Photo credit: Clint Penick.Close Modal

New funding schemes for junior faculty staff
In celebration of our 100th anniversary, JEB has launched two new grants to support junior faculty staff working in animal comparative physiology and biomechanics who are within five years of setting up their first lab/research group. Check out our ECR Visiting Fellowships and Research Partnership Kickstart Travel Grants. First deadline for applications is 15 July 2023.
JEB@100: an interview with Monitoring Editor Sanjay Sane
Sanjay Sane tells us about his first experience of publishing with the journal and why he thinks JEB is going to play a key role in our understanding of the current climate crisis and its implications for biodiversity.
The Forest of Biologists
The Forest of Biologists is a biodiversity initiative created by The Company of Biologists, with support from the Woodland Trust. For every Research and Review article published in Journal of Experimental Biology a native tree is planted in a UK forest. In addition to this we are protecting and restoring ancient woodland and are dedicating these trees to our peer reviewers. Visit our virtual forest to learn more.
Celebrating 100 years of discovery
This Special Issue focuses on broad biological questions addressed through the lens of comparative biomechanics. Crosscutting through time, this series of Reviews, Commentaries and Research Articles addresses questions from the vantage points of the history of the field, today’s research, and the future of comparative biomechanics. Read the Editorial by Sheila Patek, Monica Daley and Sanjay Sane.

Crucial DNA at crux of insect wing size evolution
Keity Farfán-Pira and colleagues have revealed that a tiny region of regulatory DNA in the vestigial gene governs whether insect wings are large or small and has played a key role in the evolution of insect wing size.
