Cover: Intertidal purple sea urchins (Strongylocentrotus purpuratus) use adhesive tube feet to stick to rocky substrates. These appendages can be amputated by predation or wave forces in these hydrodynamically turbulent environments. However, they are resilient and regenerate in a matter of days. Narvaez et al. (jeb242848) show there is a high degree of functional and morphological plasticity in these regenerating structures. The distal portion, or discs, grows back larger when subjected to turbulent flow and periodic desiccation, as often occurs in intertidal environments. Although stalk length was not affected by these conditions, the tensile breaking force of the stalks increased. Photo credit: Michael P. Russell.

Physiological effects of food availability times in higher vertebrates
Summary: Food availability times can affect physiology and reproductive fitness, and can serve as a crucial ecological determinant of metabolism, reproduction and life-history traits in higher vertebrates.
GABA receptors in the olfactory epithelium of the gilthead seabream (Sparus aurata)
Summary: The presence of GABAA receptors in the olfactory epithelium of seabream is shown by molecular, histological and electrophysiological approaches; the functional role of these receptors awaits investigation.
METHODS & TECHNIQUES
Design of a robotic zebra finch for experimental studies on developmental song learning
Summary: Development of a robot zebra finch shows that it can be used to train young males to learn a song model.
Suction feeding biomechanics of Polypterus bichir: investigating linkage mechanisms and the contributions of cranial kinesis to oral cavity volume change
Summary: Suction feeding in Polypterus bichir is driven by rapid oral cavity volume expansion, which is initiated by jaw opening, then enhanced and maintained by ceratohyal depression.
Stimulus-dependent orientation strategies in monarch butterflies
Highlighted Article: Navigating monarch butterflies employ and flexibly switch between different orientation strategies.
Ultraviolet vision in larval Neogonodactylus oerstedii
Summary: Evidence for ultraviolet vision in the larval stomatopod crustacean Neogonodactylus oerstedii is shown using electrophysiological and molecular techniques.
Responding to the signal and the noise: behavior of planktonic gastropod larvae in turbulence
Summary: Gastropod larvae alter their swimming behaviors in response to the flow around them in complex ways dependent on their time-history.
Echolocating Daubenton's bats are resilient to broadband, ultrasonic masking noise during active target approaches
Summary: Echolocating bats detect faint prey echoes and may be sensitive to noise. We demonstrate that bats are resilient to noise that overlaps spectrally, spatially and temporally with their echolocation calls.
The interplay of directional information provided by unpolarised and polarised light in the heading direction network of the diurnal dung beetle Kheper lamarcki
Summary: The diurnal dung beetle K. lamarcki relies on directional information in a Bayesian manner, affording the greatest weight to directional information conveying the highest certainty at the given moment.
Eri silkworm spins mechanically robust silk fibers regardless of reeling speed
Summary: The structural, morphological and mechanical features of eri silk fibers are maintained irrespective of the reeling speed.
Recognition of natural objects in the archerfish
Editor's choice: Archerfish are capable of natural object recognition and categorization based on a small number of visual features.
The resting frequency of echolocation signals changes with body temperature in the hipposiderid bat Hipposideros armiger
Summary: In Hipposideros armiger, the variation of body temperature during activation phases results in a concomitant change in emission frequency.
A change in taste: the role of microRNAs in altering hedonic value
Summary: Injecting poly-l-lysine into Lymnaea stagnalis to block the Dicer-mediated biogenesis of microRNAs decreases the hedonic value of food stimuli.
Plasticity in fluctuating hydrodynamic conditions: tube foot regeneration in sea urchins
Summary: Sea urchin tube feet show morphological and adhesive plasticity when exposed to contrasting hydrodynamic conditions.
Irreversible impact of early thermal conditions: an integrative study of developmental plasticity linked to mobility in a butterfly species
Summary:Pieris napi butterflies raised under warm or cool conditions show morphological differences associated with changes in self-maintenance, flight and reproductive performance, indicating long-term consequences of plasticity on adult traits. This plasticity might benefit acclimation processes to seasonality.

Meet the JEB Editors @ SEB 2023
Come and meet the JEB team at the Society for Experimental Biology centenary conference from 4-7 July in Edinburgh, UK. Visit exhibition stand 13/15 to pick up JEB centenary goodies, including our new ‘100 years of discovery’ T shirt, and join our Meet the JEB Editors event on Thursday 6 July at 12.30 at Platform 5 to find out more about the journal and chat to Editors including EiC Craig Franklin, Monitoring Editors Sanjay Sane, Trish Schulte and John Terblanche and the in-house News and Reviews team.
New funding schemes for junior faculty staff
In celebration of our 100th anniversary, JEB has launched two new grants to support junior faculty staff working in animal comparative physiology and biomechanics who are within five years of setting up their first lab/research group. Check out our ECR Visiting Fellowships and Research Partnership Kickstart Travel Grants. First deadline for applications is 15 July 2023.
JEB@100: an interview with Monitoring Editor Katie Gilmour
Katie Gilmour tells us how she first encountered the JEB Editorial team as a graduate student at the University of Cambridge, UK, and how she would like to have a Star Trek tricorder to monitor fish non-invasively in the field.
The Forest of Biologists
The Forest of Biologists is a biodiversity initiative created by The Company of Biologists, with support from the Woodland Trust. For every Research and Review article published in Journal of Experimental Biology a native tree is planted in a UK forest. In addition to this we are protecting and restoring ancient woodland and are dedicating these trees to our peer reviewers. Visit our virtual forest to learn more.
Centenary Review - Adaptive echolocation behavior
Cynthia F. Moss and colleagues discuss the behaviours used by echolocating mammals to track and intercept moving prey, interrogate dynamic sonar scenes, and exploit visual and passive acoustic stimuli.
Crucial DNA at crux of insect wing size evolution
Keity Farfán-Pira and colleagues have revealed that a tiny region of regulatory DNA in the vestigial gene governs whether insect wings are large or small and has played a key role in the evolution of insect wing size.
