Abstract Many Arctic fishes experience prolonged periods of extreme cold and large thermal variation over both rapid and seasonal time scales which challenge critical physiological functions. In the central Canadian Arctic, we caught wild adult lake trout (Salvelinus namaycush) acclimatized to winter and summer temperatures to determine the extent to ...

The raphe nuclear organization and serotonergic system in the bat (Artibeus planirostris)
Schematic representation of the methodological workflow used to characterize the serotonergic (5‐HT) system in the bat Artibeus planirostris. Serotonin (5‐HT) immunohistochemistry was performed on brainstem sections to identify and map the distribution of serotonergic neurons within the raphe nuclei.

Leidyosuchus canadensis and Stangerochampsa mccabei share endocranial features such as posterior projection of a neurovascular canal in the maxilla and a paratympanic sinus system most similar to those of small‐bodied and young extant crocodylians, suggesting that these pedomorphic features may reflect the ancestral crocodylian condition.

Thermographic Behaviour of the Orbicularis Oris Muscle Under Different Provocative Tests
Study design showing the thermographic region of the orbicularis oris muscle (Picture 1), the foods used for chewing and the increase in mean temperature after the provocative tests (Picture 2). ABSTRACT Background Infrared thermography is an objective method for investigating muscle functioning, enabling inferences about physiology and therapeutics ...

ABSTRACT Recent studies have shown that acoustic stimulation, a common neuromodulation technique, can enhance slow‐wave activity (SWA), which is associated with immune, autonomic nervous system activity and cognitive health benefits. Despite some disagreement, many studies suggest that maximising tone‐evoked SWA depends on the timing of the acoustic ...

In our recent study, we examined whether ants in the Brazilian Cerrado follow the “grain‐size hypothesis,” which proposes that larger ants should have proportionally longer legs to move efficiently across different environments. We used Ectatomma permagnum, a common predatory ant in the Cerrado, measuring hundreds of individuals collected from various ...

The metabolic cold adaptation hypothesis posits that populations inhabiting higher latitudes and altitudes will have increased metabolic rates to compensate for colder temperatures and shorter activity periods constraining energy use. This compensatory evolution may be exhibited in ectotherms that grow faster and larger in colder environments compared ...

Rapid postfire color shift in a Mediterranean lizard
We quantified dorsal luminosity and color composition of Psammodromus algirus in burned and adjacent unburned habitats at different times since fire. Lizards inhabiting recently burned areas displayed lighter dorsal coloration, particularly during the early stages of postfire succession, with the effect being more pronounced in larger individuals ...
