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.

REVIEW
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.
SHORT COMMUNICATION
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.
RESEARCH ARTICLES
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.

Photosynthesis turns symbiotic sea anemone's tentacles toward sun
Snakelocks sea anemones point their tentacles, packed with symbiotic algae, toward the sun so their lodgers can photosynthesize, and now Vengamanaidu Modepalli & colleagues have discovered that photosynthesis by the algae guides their host's tentacles towards the sun.
