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