Cover ImageCover: With large eyes, razor-sharp mandibles and a solitary foraging style, bull ants (genus Myrmecia) are oddities in the ant world. Of two closely related sympatric species in Australia, one is diurnal and the other nocturnal. Jayatilaka and colleagues (pp. 2730-2738) investigated whether differences in temperature tolerance restrict their activity period. This is clearly not the case: both ants tolerate higher temperatures than they naturally encounter, and daily and seasonal foraging patterns are affected by temperature only in the diurnal ant. Thermal biology does not drive temporal niche partitioning in these ants, but temperature has varied effects even amongst congeneric species. Photo credit: A. Narendra.

Meet the JEB Editors @ SEB 2023
Come and meet the JEB team at the Society for Experimental Biology centenary conference from 4-7 July in Edinburgh, UK. Visit exhibition stand 13/15 to pick up JEB centenary goodies, including our new ‘100 years of discovery’ T shirt, and join our Meet the JEB Editors event on Thursday 6 July at 12.30 at Platform 5 to find out more about the journal and chat to Editors including EiC Craig Franklin, Monitoring Editors Sanjay Sane, Trish Schulte and John Terblanche and the in-house News and Reviews team.
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 Katie Gilmour
Katie Gilmour tells us how she first encountered the JEB Editorial team as a graduate student at the University of Cambridge, UK, and how she would like to have a Star Trek tricorder to monitor fish non-invasively in the field.
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.
Centenary Review - Adaptive echolocation behavior
Cynthia F. Moss and colleagues Review the behaviours used by echolocating mammals to track and intercept moving prey, interrogate dynamic sonar scenes, and exploit visual and passive acoustic stimuli.
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.
