JEB: 100 years of discovery

Summary: Diapause is nearly universally employed by insects for surviving unfavorable seasons. In spite of impressive progress that has been made in understanding diapause, many exciting questions remain unanswered.

Summary: Climate change-induced temperature increases will have both positive and negative effects on insect immune systems; consequently, insect susceptibility to disease is difficult to predict. We discuss how future research can answer this key question.


Summary: Channel catfish vary suction feeding performance by modulating co-contraction of epaxial and hypaxial muscles.

Summary: Selective breeding for high levels of voluntary wheel-running behavior in house mice alters the gut microbiota composition and diversity at weaning, indicating a possible regulatory role for the microbiome in exercise behavior.

Highlighted Article: Light pollution during development reduces heat tolerance in a field cricket, but its effects on desiccation tolerance are dependent on flight capability.


Summary: Three-dimensional reconstructions of hoverfly bead pursuits in an indoor arena show two behavioral strategies: a distal stage, which rapidly decreases the target distance, and a proximal stage, where the hoverfly shadows the target.

Highlighted Article: Data from acceleration–depth data loggers show that during chick rearing, European shags (Gulosus aristotelis) did not follow classical optimal foraging rules but instead foraged opportunistically.

Summary: Despite generally rigid bodies, bluefin tuna are capable of maneuvering with high agility by using various turning behaviors, with a flexible tail and caudal peduncle.

Summary: Cardiac taurine deficiency impairs heart function in brook char and alters whole-animal sensitivity to thermal, hypoxic and exercise stress.

Highlighted Article: Transcriptome sequencing of maternal mouthbrooding cichlid whole brains identifies a number of candidate neuropeptides and hormones involved in parental behavior as well as general oxygen transport, metabolic processes and neuroprotective pathways likely induced by the metabolic stress of fasting.

Editor's choice: Within 1–2 months after settlement, juvenile snapping shrimp develop an elastic mechanism that allows them to generate ultrafast strikes, cavitation bubbles and the highest recorded accelerations for underwater, repeated-use movements.

Summary: Centipedes use a presumed passive strategy to negotiate limb–substrate collisions. One centipede species changes its limb-stepping pattern, hypothesized to reduce footfall uncertainty.

Summary: Pelage contrast and small dark patches are key to enabling stripes preventing zebras being attacked by biting flies.

Summary: Increased myocardial compaction in seawater-acclimated rainbow trout is associated with greater reliance on coronary perfusion for cardiorespiratory performance.

Highlighted Article: Acanthopleura granulata exhibits polarization sensitivity, and sensory information gathered by its distributed visual system is integrated in a decentralized visuotopic map.
