Cover: New technology constantly opens up possibilities for research in orientation and navigation. Combining different sensors allows especially detailed insights into the behaviour of animals in the wild. Here, an Egyptian fruit bat (Rousettus aegyptiacus) is carrying a tag that records movement through acceleration, position via GPS and echolocation with a microphone. In their review, Greif and Yovel (jeb184689) demonstrate how sound recordings on animals can be used to infer a variety of behaviours. This could be vocalisations like echolocation calls (in red), but also wing beat during flight (illustrated with an oscillogram in yellow, confirmed through acceleration recordings in blue).

Special Issue: Linking Brain and Behaviour in Animal Navigation

EDITORIAL
REVIEWS
Olfactory navigation in aquatic gastropods
Summary: Review of the past research and future prospects for understanding odour-based navigation behaviour by gastropods, covering behavioural patterns, navigational strategies and neural underpinnings.
Behavioural and neuronal basis of olfactory imprinting and kin recognition in larval fish
Summary: This Review focuses on olfactory imprinting processes that numerous species use to recognize kin or their natal environment later in life.
There and back again: natal homing by magnetic navigation in sea turtles and salmon
Summary: New findings indicate that long-distance natal homing in salmon and sea turtles involves an ability to navigate back to the magnetic signature of the home area.
The internal maps of insects
Summary: Insect behaviour can be explained as a combination of path integration, vector memory and view memory, but what is the evidence that these geometric capabilities form an integrated map?
The genetics and epigenetics of animal migration and orientation: birds, butterflies and beyond
Summary: This Review summarizes our understanding of the genetics and epigenetics of animal migration and outlines a vision to harness both technical advances and comparative approaches to move the field forward.
Non-Euclidean navigation
Summary: The behavioral evidence for Euclidean cognitive maps is unpersuasive. Recent experiments indicate that human spatial knowledge is better described by a labeled graph, which incorporates local distance and angle information.
Using on-board sound recordings to infer behaviour of free-moving wild animals
Summary: We review new possibilities for monitoring the behaviour of wild animals in the field using on-board audio recordings.
The potential of virtual reality for spatial navigation research across the adult lifespan
Summary: This Review describes how virtual reality is used to study spatial navigation across species and discusses the benefits and challenges when using it in older age groups.
The insect central complex and the neural basis of navigational strategies
Summary: Neural circuits of the insect central complex are involved in guiding multiple navigation strategies, and the emerging core circuit for navigational decisions might provide an overarching framework of central-complex function.
Celestial navigation in Drosophila
Summary: In this Review, we describe how the fruit fly, Drosophila melanogaster, uses the position of the sun and the pattern of polarized skylight to maintain a constant heading during long-distance dispersal flights.
The brain behind straight-line orientation in dung beetles
Summary: Insights into the neural mechanisms underlying compass orientation in dung beetles are placed into the context of the mechanisms of other insects.
Origin and role of path integration in the cognitive representations of the hippocampus: computational insights into open questions
Summary: Path integration is one of the fundamental computations giving rise to the cognitive map and possibly other non-spatial representations in the hippocampal formation and its subcortical afferents.
Merging information in the entorhinal cortex: what can we learn from robotics experiments and modeling?
Summary: Grid cells related to path integration and vision are explained as modulo projections of different cortical activities. The entorhinal cortex appears as a generic merging tool building hash codes.
Navigation and the developing brain
Summary: Spatial development in humans takes a decade or more to unfold, and involves tuning initial systems in response to changing motor capacities and environmental feedback.
The navigational nose: a new hypothesis for the function of the human external pyramid
Summary: The human nose respires and sniffs yet current theory addresses only its respiratory function; the nose may also allow stereo olfaction and may have evolved for this in early Homo.
In the field: an interview with Harald Wolf
(update)-Conversation.jpg?versionId=3747)
In our new Conversation, Harald Wolf talks about his fieldwork experiences working with desert ants in Tunisia to understand their navigation.
Propose a new Workshop
-GSWorkshop.png?versionId=3747)
Our Workshops bring together leading experts and early-career researchers from a range of scientific backgrounds. Applications are now open to propose Workshops for 2024, one of which will be held in a Global South country.
Julian Dow steps down and John Terblanche joins the JEB team
-NewEditor.png?versionId=3747)
After 15 years with the journal, Julian Dow from University of Glasgow, UK, is stepping down as a Monitoring Editor. We wish Julian all the best for the future and welcome John Terblanche, Stellenbosch University, South Africa, who is joining the team. Julian talks about his long association with The Company of Biologists and the journal and John tells us about his life and career in this News article.
The capture of crude oil droplets by filter feeders at high and low Reynolds numbers
-FilterFeeders.jpg?versionId=3747)
Researchers from the University of Montreal, Canada, reveal how tiny filter feeding barnacles and Daphnia entrap and consume minute droplets of crude oil, introducing the pollutant at the bottom of the food chain.
Patterns and processes in amphibious fish
-Review.png?versionId=3747)
In their Review, Keegan Lutek, Cassandra Donatelli and Emily Standen discuss the biomechanics and neural control of terrestrial locomotion in amphibious fish. They explore how locomotor mode depends on body shape, physical constraints and phylogeny.
