Effects of eyestalk ablation (ESA) on hemolymph ecdysteroid, nitric oxide synthase (NOS) and guanylyl cyclase expression in red (triangles) and green (squares) morphs over 24 and 16 days, respectively. Animals were eyestalk-ablated at Day 0. YOs were harvested and hemolymph samples were taken at various intervals post-ESA. Ecdysteroid levels were quantified by ELISA. mRNA levels were quantified by qPCR. Data are presented as means ± 1 s.e.m. (red morph, N=7, 3, 6 and 3 at Days 0, 3, 14 and 24, respectively; green morph, N=13, 5, 5, 5 and 4 at Days 0, 3, 7, 14 and 16, respectively). Different letters (numbers) indicate green (red) morphs that are significantly different (P<0.05) from each other.

The JEB Editors are delighted to announce the shortlisted authors for the 2023 JEB Outstanding Paper Prize. Read the winning paper - Tiny spies: mosquito antennae are sensitive sensors for eavesdropping on frog calls - by Hoover Pantoja-Sanchez and Brian Leavell from Ximena Bernal's lab at Purdue University, USA.
If you’re an early-career researcher interested in science communication and are attending the SEB Annual Conference in Prague this summer, come a day early and join the JEB Editors at a sci comm workshop to learn the key writing skills needed to promote your research to a broad audience beyond your peers (1 July at 14.30-17.30). Places are limited to 24 attendees, and applicants should apply through the SEB registration page by 30 April 2024.
Novel technologies enable behavioural experiments with non-model species, in naturalistic habitats and with underexplored behaviours. In their Commentary, Scholz and colleagues discuss how to obtain a deeper understanding of the natural ecology and lifestyle of study animals.
To help save animals from extinction, it’s important to understand what each species needs to survive. This led Jason John et al. to measure the metabolic rates of captive belugas to develop a ‘fish calculator’ showing that the whales need to eat ~23 salmon per day.
Are you an ECR looking for tips on how to write concise, astute and useful manuscript reviews? If so, join the JEB Editors at a 2-hour JEB-sponsored Workshop on Positive Peer Review at the Canadian Society of Zoologists annual meeting in Moncton on 9 May 2024 at 13.00-15.00. There are 25 spaces for ECRs and selection is first come, first serve. To sign up, check the ECR Workshop box when you register for the CSZ meeting.
