Issues

Summary: Coral species vary in their reliance on particulate food sources but food availability affects only certain aspects of coral physiology. Changes in species composition of reefs are likely to affect the fluxes of organic matter between reefs and the open ocean.

Highlighted Article: Muscle contractile properties determine voluntary movement speed and activity of animals, and thereby influence risk-taking behaviour, providing a functional explanation for differences in behavioural phenotypes between individuals.

Summary: Cold and exercise training in house sparrows increase trans-sarcolemmal and intramyocyte lipid transport capacities and cellular metabolic intensities associated with elevated shivering thermogenesis and exercise capacities.

Summary: Eccentric exercise induces immediate changes in biaxial transverse strain of the human Achilles free tendon in vivo that appear to be linked to corresponding creep-dependent changes in longitudinal strain.

Summary: Oxidative damage does not increase in female bank voles rearing four enlarged litters, which undermines the hypothesis linking oxidative stress with the trade-off between current and future reproductive effort.

Summary: Experimental manipulation of litter size in wild-derived mice increases oxidative challenges in large litters and influences investment in sexual signalling, indicating long-term effects of rearing environment.

Summary: Predator kairomones perceived by anuran embryos induce life-history and behavioural changes in tadpoles, and result in a long-term increase in neuronal activity and response to predator cues.

Highlighted Article: The water channel aquaporin-1a1 contributes to CO₂ and ammonia excretion in zebrafish larvae, indicating that it serves in vivo as a gas channel for CO₂ and ammonia movement across biological membranes.

Summary: Disparate jaw morphologies are functionally equivalent in a diverse family of hard-prey-feeding stingrays, despite their prey spanning a continuum of shell structural and material properties.

Summary: Light-driven activity patterns exist in vivo for pyloric and gastric mill rhythms, but are overshadowed by substantial variability and occluded by sensory influences, which alter motor pattern structure.

Highlighted Article: Prawns consume more schistosome-infected snails than uninfected snails; infected snails exhibit altered behavior that may contribute to this preference.

Summary: Crickets alter the orientation of their wind-elicited walking behavior and response threshold after exposure to a 10 kHz sound stimulus, suggesting a multisensory interaction between the auditory and cercal sensory systems.

Highlighted Article: For snake locomotion, the effects of surface roughness and steepness are interactive and species dependent, partly because some species have specialized non-cylindrical shapes that facilitate catching small surface protrusions.

Summary: Dolphins use sonar to hunt fish; they make different sounds and different decisions simultaneously.

Summary: The 3D direction of an escape response by a larval zebrafish is correlated with the degree of body rotation in yaw and pitch.

Summary: Transcriptomic profiling of the pars intercerebralis in the honey bee brain provides mechanistic insights into how neurosecretory signals mediate social behavior.
