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.

Editorial – The changing of the guard
In his Editorial, Hans Hoppeler announces that he will be stepping down as Editor-in-Chief of JEB in July 2020. He reflects on the history of JEB, why he has enjoyed his tenure as JEB’s Editor-in-Chief and the recent developments in the publishing world.
Editors’ choice – Parental stressor exposure simultaneously conveys both adaptive and maladaptive larval phenotypes through epigenetic inheritance in the zebrafish (Danio rerio)
An oil spill is never a good thing, but Naim Bautista and Warren Burggren have shown that zebrafish can pass on resistance to the damaging effects of an oil-spiked diet to their offspring.
The derivative of force with respect to time does not have a standard term in physics. In their new Commentary, David C. Lin and his colleagues propose that the term ‘yank’ should be used to denote the time derivative of force.
Runners waste energy every time their legs stop swinging, but now a team of scientists from the US and Canada have shown that a springy ankle tether can reduce runners’ energy costs by 6.4%, which is nearly the entire cost of swinging the limbs. Read the full research article here.
Journal of Experimental Biology is pleased to announce a new partnership with Publons! This allows reviewers to easily track and verify every review by choosing to add the review to their Publons profile when completing the review submission form. Publons also makes it simple for reviewers to showcase their peer review contributions in a format that can be included in job and funding applications (without breaking reviewer anonymity). Read the official announcement here!
The Company of Biologists provides grants to fund scientific meetings, workshops and conferences in the fields covered by our journals. Typically, meetings with fewer than 100 people may be granted up to £2,000, increasing up to £6,000 for about 400 people. The next deadline to apply is 28 November 2019.
