Issues

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.

Summary: The presence of GABA_A receptors in the olfactory epithelium of seabream is shown by molecular, histological and electrophysiological approaches; the functional role of these receptors awaits investigation.

Summary: Development of a robot zebra finch shows that it can be used to train young males to learn a song model.

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.

Highlighted Article: Navigating monarch butterflies employ and flexibly switch between different orientation strategies.

Summary: Evidence for ultraviolet vision in the larval stomatopod crustacean Neogonodactylus oerstedii is shown using electrophysiological and molecular techniques.

Summary: Gastropod larvae alter their swimming behaviors in response to the flow around them in complex ways dependent on their time-history.

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.

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.

Summary: The structural, morphological and mechanical features of eri silk fibers are maintained irrespective of the reeling speed.

Editor's choice: Archerfish are capable of natural object recognition and categorization based on a small number of visual features.

Summary: In Hipposideros armiger, the variation of body temperature during activation phases results in a concomitant change in emission frequency.

Summary: Injecting poly-l-lysine into Lymnaea stagnalis to block the Dicer-mediated biogenesis of microRNAs decreases the hedonic value of food stimuli.

Summary: Sea urchin tube feet show morphological and adhesive plasticity when exposed to contrasting hydrodynamic conditions.

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.
