Summary: The nervous system does not simply endure hibernation; instead, it actively promotes and supports this complex physiological process.


Summary: Demonstration of the use of calibrated computed tomography to accurately quantify the three-dimensional centre of mass and moments of inertia of birds of prey.

Summary: To characterize the sound-induced motion of fish auditory structures in 4D, we developed a tomography-compatible standing wave tube-like setup and thereby demonstrated the previously hypothesized rotational motion of otophysan sagittae.


Summary: The energetic burden of Lepeophtheirus salmonis lice infections of different life-stages and intensities in young Atlantic salmon assessed with an aerobic scope framework.

Summary: Oyster mitochondria show tissue-specific substrate preferences with low propensity for reverse electron transport. Hypoxia–reoxygenation stress suppresses mitochondrial oxidation capacity for NADH-linked substrates but enhances succinate oxidation, thus supporting post-hypoxic recovery.

Highlighted Article: Wing damage in house flies progresses according to a logistic function, albeit with large inter-individual differences; animals can still fly with two-thirds of wing area remaining.

Highlighted Article: Parrots ascend primarily by pulling upward from an overhead branch using the beak and feet, while resisting the gravitational pitching moment with horizontal force couples of the beak, feet and tail.

Summary:In vivo labeling experiments demonstrate that a population of myoblasts continues proliferating, and muscle hypertrophy but not hyperplasia is inhibited under growth adverse conditions in the teleost Odontesthes bonariensis.

Summary: Feeding mechanics in caecilians is complex. No relationships between bite force and skull shape were detected, but our results do suggest variation in how caecilians use their jaw-closing muscles.

Summary: Mitochondrial properties of red-footed tortoises may underlie their slower senescence rates and increased lifespan.

Summary: Sound detection is complex in crustaceans and a multitude of sensory receptors are likely to be involved.

Summary: In goldfish, constant hypoxia leads to greater benefits in swimming performance in normoxia. Frequency of exposure to environmental hypoxia could be a key driver of mitochondrial metabolic adjustments.

Summary: Nutritional bacterial symbionts of the saw-toothed grain beetle Oryzaephilus surinamensis enhance host cuticle formation, conferring protection against predation and fungal infection.
