Issues

Summary: Reflections on the first issue of JEB in 1923.

Summary: This Review explores the behavioral and neural mechanisms that insects use to locate food and mates using their sense of smell.

Summary: Arctic seals control heat loss in water and when hauled out to limit energetic costs, even during the annual molting period when tissue regeneration and hair growth occur.

Highlighted Article: Functional changes in the tadpole gut microbiome in response to heat may allow for a dampened host response and ultimately buffer hosts from the deleterious effects of heat stress.

Summary: The viscoelastic properties of salmon ovarian fluid support a novel mechanism of post-mating sexual selection in external fertilisers with important implications for understanding the evolution of sexual traits.

Highlighted Article: Analysis of behavior, physiology and gene expression related to hypoxia and hypercapnia demonstrate that the overall impacts of CO₂ in bumble bees are unique and are not induced by anoxia. The CO₂ impacts in bees are dependent on dose, caste and mating status.

Summary: Catecholamines modulate the hypoxic ventilatory response through central β-adrenergic receptors.

Summary: The foot chamber of the clam Calyptogena okutanii is divided into two compartments by a dense muscle zone (fastener zone) that controls extension/retraction of the foot, similar to Keber's valve.

Summary: The performance of bumble bees while learning a bimodal cue depends on the internal structure of the signal and the temporal configuration of the presentation of the components.
