Screenshot of the first page of the PDF of the Review article, Transgenerational plasticity and climate change: phenotypic responses across ectothermic animals, by Anthony Gilbert and Daniel Warner. The publishing information states: © 2026. Published by The Company of Biologists | Journal of Experimental Biology (2026) 229, jeb250304. doi:10.1242/jeb.250304. The first sentence of the Abstract says, 'Using organismal-level data to predict population-level responses to climate change is a common, yet complicated challenge'.

In their Review, Gilbert & Warner discuss how warming due to climate change can have effects across multiple generations of ectotherms and highlight knowledge gaps which would benefit from future research

Atlantic bluefin tuna are some of the top predators in the ocean and now an international team of researchers has successfully measured the fish's oxygen consumption, allowing them to estimate that bluefin tuna consume ∼650 mg O2/h when cruising

The front cover of Journal of Experimental Biology issue 4, volume 229, published February 2026, shows four dolphins swimming in shallow water. The image is taken from below looking up toward the surface. The central dolphin is entirely visible and takes up 1/3 of the image, the other three dolphins are located around the central dolphin and are either much smaller because they are further away, or are only partially visible because they are at the edge of the shot. An insert in the bottom right shows a sequence (10) electrical impedance tomography reconstructions taken over the course of a single breath. The Company of Biologists logo is in the bottom left corner.

Issue 4 has closed and issue 5 is open
The front cover by Dolphin Quest shows bottlenose dolphins (Tursiops spp.) just beneath the surface & accompanies research by Fahlman&co using electrical impedance tomography to visualise lung ventilation while diving

Screenshot of the first page of the PDF of the Review, The CO2 and humidity senses of insects in a changing world, in the Sensory Perception in a Changing World Special Issue. The Review is by Ajinkya Dahake. The publishing information states: © 2026. Published by The Company of Biologists | Journal of Experimental Biology (2026) 229, jeb251089. doi:10.1242/jeb.251089. The first sentence of the Abstract states: 'The ability to detect carbon dioxide and water vapor is essential for insect survival. Insects possess specialized receptors and anatomical structures that confer remarkable sensitivity to these environmental factors'.

Water & CO2 are prominent greenhouse gases. In his SI Review, Ajinkya Dahake discusses how insects sense H2O & CO2, and use the senses to locate plants, hosts & for navigation, although increasing CO2 could desensitise insects affecting host location

Fish are at particular risk of climate change as their physiology is finely tuned by the temperature of their surroundings. Suzanne Currie & Julia York discuss how fish sense temperature & how the fish's own physical condition might impact their sensitivity
