- Effects of repeated daily acute heat challenge on the growth and metabolism of a cold water stenothermal fish
Summary: Maximum metabolic rates of fish display plasticity to intermittent exposure to warm water.
- Vision is highly sensitive to oxygen availability in marine invertebrate larvae
Editors' Choice: Reduced oxygen availability decreases retinal sensitivity and temporal resolution in marine invertebrate larvae, which may impact visual behaviors crucial to survival and increase vulnerability of species to ocean oxygen loss.
- Effects of the maternal and current social environment on female body mass and reproductive traits in Japanese quail (Coturnix japonica)
Summary: The maternal and current social environment have interacting effects on body mass of female Japanese quail, but only the current social environment affects reproductive traits and offspring mass at hatching.
- Molecular interactions underpinning the phenotype of hibernation in mammals
Summary: This Review covers recent advances in the molecular biology of hibernation with a focus on molecular interactions underlying the hibernation phenotype.
- Telomere elongation during early development is independent of environmental temperatures in Atlantic salmon
Summary: The authors show that, in salmon, telomeres significantly lengthen between the embryonic and larval stages of development, and that this is not influenced by environmental temperature.
- Role of outstretched forelegs of flying beetles revealed and demonstrated by remote leg stimulation in free flight
Summary: The forelegs of beetles were found to voluntarily swing to assist with flight yaw rotation. Remote control of left–right turnings by inducing leg swings was demonstrated via a wireless electrical stimulator.
- Mechanisms underlying the control of responses to predator odours in aquatic prey
Summary: A review of the mechanisms known to date that mediate the diversity of responses seen in aquatic prey exposed to predator odours and their associated diet cues.
- Mutualistic damselfish induce higher photosynthetic rates in their host coral
Editor's Choice: The results of this experimental study show, for the first time, a positive contribution of the coral-dwelling damselfish Dascyllus marginatus on the photosynthesis of their host, the coral Stylophora pistillata.
- A new cue for torpor induction: charcoal, ash and smoke
Highlighted Article: Torpor expression is enhanced in yellow-footed antechinus in response to a combination of fire cues (food restriction, smoke and a charcoal/ash substrate), indicating a previously unrecognised regulatory mechanism for thermal biology in mammals.
- Demystifying animal ‘personality’ (or not): why individual variation matters to experimental biologists
Summary: Approaches used in quantitative genetics and animal personality research are useful to study the ecological and evolutionary consequences of individual variation in behaviour, physiology, performance and other complex traits.
