Cover: Tropical corals are currently facing mass bleaching events around the world. Using the model species Stylophora pistillata (pictured here in a close-up of the polyps with tentacles surrounding the mouth, photographed with a macrofluorescence microscope), Crehan et al. (jeb246466) found that when corals experience heat stress events, they lose their ability to take up nitrogen from the seawater, resulting in their endosymbiotic algae becoming starved of nitrogen. However, to compensate, they take up more urea. This suggests that fish, and the urea they produce, may play a key role in mitigating the extent of coral bleaching. Photo credit: Eric Tambutté.

COMMENTARY
A translational and multidisciplinary approach to studying the Garcia effect, a higher form of learning with deep evolutionary roots
Summary: This Commentary addresses the Garcia effect – a long-lasting taste aversion induced after sickness. Studies from snails suggest it extends beyond mammals, prompting further investigation into its conserved evolution across species.
RESEARCH ARTICLES
The effects of muscle starting length on work loop power output of isolated mouse soleus and extensor digitorum longus muscle
Summary: The force–length relationship derived from static conditions may not predict force output during dynamic contractions as differing muscle starting lengths are needed to evoke maximal force and power.
Effects of microRNA-305 knockdown on brain gene expression associated with division of labor in honey bee colonies (Apis mellifera)
Summary: Knockdown of microRNA-305 in abdominal fat body of adult honey bee workers influences division of labor-related brain gene expression but not division of labor-related changes in abdominal lipid.
Nutrient depletion and heat stress impair the assimilation of nitrogen compounds in a scleractinian coral
Summary: Increased temperatures and nutrient depletion decrease the ability of corals to assimilate nitrogen, leading to nitrogen limitation in their endosymbiotic algae.
Effects of ingesting large prey on the kinematics of rectilinear locomotion in Boa constrictor
Summary: Although a large prey bolus may impede movement and lengthen propulsive muscles for rectilinear locomotion, few kinematic changes occur in Boa constrictor following the ingestion of large prey.
Dietary restriction and life-history trade-offs: insights into mTOR pathway regulation and reproductive investment in Japanese quail
Summary: Application of four levels of dietary restriction to simulate resource scarcity in Japanese quail shows that mTOR pathway gene expression responds to nutritional deficiency, possibly mediating the trade-offs between life-history traits.
Bumblebees compensate for the adverse effects of sidewind during visually guided landings
Highlighted Article: Bumblebees foraging in strong sidewinds can still land precisely on artificial flowers, allowing them to be efficacious and robust pollinators in these adverse environmental conditions.
Carry-over effect of artificial light at night on daytime mating activity in an ecologically important detritivore, the amphipod Gammarus pulex
Highlighted Article: Artificial light at night not only reduces formation of amphipod precopulatory mate guarding at night, but also increases pair separation during the day.
Growth, filtration and respiration characteristics of small single-osculum demosponge Halichondria panicea explants
Summary: Sponges are modular organisms and in order to grow, new modules must be formed, but the growth of a single module is fundamentally different, with filtration rate scaling to module volume as F/V∝V1/3.
Center of mass position does not drive energetic costs during climbing
Summary: Broad changes in posture, anatomical variation or expertise do not reveal benefits in climbing.
Evaluating the role of social context and environmental factors in mediating overwintering physiology in honey bees (Apis mellifera)
Summary: In honey bees, seasonal environmental factors beyond brood area may be necessary for bees to develop their winter phenotype.
Scaling of buccal mass growth and muscle activation determine the duration of feeding behaviours in the marine mollusc Aplysia californica
Summary: As Aplysia grows, biting behaviour duration is determined by the time constant of muscle activation rather than mechanical forces. Swallowing movements are faster because the jaw muscles grow disproportionally larger.
ECR SPOTLIGHTS
Embracing allyship in experimental biology to help close the gender gap

In their Perspective, Janneke Schwaner and Ksenia Keplinger propose 10 useful strategies for experimental biologists at all career stages to become active allies for gender diversity and inclusion and to help close the gender gap in our field.
The Company of Biologists celebrates its first Global South Workshop

In March 2024, Andrea Fuller and Kênia Bicego organised the first Global South (GS) Workshop hosted by The Company of Biologists - How Global South Research Can Shape the Future of Comparative Physiology - bringing together ECRs from the GS and international experts in the Kruger National Park, South Africa. Find out about this extraordinary meeting in our Perspective.
High-resolution WildPose 3D scans revolutionise biomechanics in the wild

Collecting detailed kinematics from animals in the wild is a holy grail of biomechanics, and now Naoya Muramatsu and colleagues reveal the extraordinary observations that they have made with their new WildPose wildlife motion capture system in South Africa.
