Cover: A pair of downstream-migrating, juvenile sea lampreys (Petromyzon marinus L.) that have just completed their transformation from substrate-dwelling, filter feeders into free-swimming, parasitic feeders. Lampreys are the most primitive osmoregulating vertebrates and this species has an anadromous life history. During metamorphosis branchial seawater-type mitochondria-rich cells first appear, gill Na+/K+-ATPase activity increases and hypo-osmoregulatory ability improves markedly, all indicating a preparatory adaptation for life at sea (see article by P. Reis-Santos, S. D. McCormick and J. M. Wilson, pp. 978−988), and abundant Na+/K+-ATPase (red staining) is associated with these cells. Photos by Jonathan Wilson; thanks to Dr Carlos Antunes for supplying the lampreys. - PDF Icon PDF LinkTable of contents
Meet the JEB Editors @ SEB 2023
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.
