Cover: This juvenile Apteronotus leptorhynchus, or brown ghost knifefish, belongs to one of approximately 200 species of South American gymnotiform weakly electric fishes. These animals use an active electrosense for foraging at night in often turbid waters as well as for communication. The total energetic cost of their electric behaviour, including generation and sensing of the electric field, is estimated to be about 30% of routine metabolic rate (Salazar et al., pp. 2459−2468). The articles in this special issue review the remarkable recent contributions of research on electric fishes to energetics and many other areas of biology.

INSIDE JEB
Harnessing physiological research for smarter environmental policy

In their Perspective, Alexia Dubuc and colleagues discuss strategies to strengthen collaboration, communication and engagement between physiological researchers and environmental policy makers to ensure that conservation strategies address the threats posed by climate change.
JEB grants to support junior faculty

Learn about the grants that we launched in 2023 to support junior faculty from two of our awardees: Erin Leonard, Early-Career Researcher (ECR) Visiting Fellowship recipient, and Pauline Fleischmann, Research Partnership Kickstart Travel Grant recipient. The next deadline to apply is 28 November 2025.
Early testing could make risky falls a thing of the past for elderly people

Falls cost healthcare systems billions each year, but there may be a solution. Jiaen Wu and colleagues of Stanford University, USA, suggest that measuring the way someone walks before they get old might let doctors know who is at risk for a potentially life-threatening fall in the future.
Ecosystem engineers on tropical reefs in transition

Giant barrel sponges (GSBs) remain robust to rising seawater temperatures and have rapidly populated reefs stripped of coral cover by climate change. GBSs may be poised to become the dominant habitat-forming organisms in tropical reef ecosystems of the future. In this Review, Joseph Pawlik provides an integrative and critical assessment of research on giant barrel sponges.
Fast & Fair peer review

Our sister journal Biology Open has recently launched the next phase of their Fast & Fair peer review initiative: offering high-quality peer review within 7 working days. To learn more about BiO’s progress and future plans, read the Editorial by Daniel Gorelick, or visit the Fast & Fair peer review page.
