- 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.
- Preferential intracellular pH regulation: hypotheses and perspectives
Summary: Preferential intracellular pH regulation confers exceptional tolerance to a severe acute respiratory acidosis. This trait may represent a basal pattern of acid–base regulation used by developing vertebrates that is lost or retained in adults.
- Embryonic common snapping turtles (Chelydra serpentina) preferentially regulate intracellular tissue pH during acid–base challenges
Summary: Embryonic turtles preferentially regulate tissue pH in the absence of blood pH regulation during acid–base disturbances. This pattern of acid–base regulation has never been observed before in amniotes.
- Characterising multi-level effects of acute pressure exposure on a shallow-water invertebrate: insights into the kinetics and hierarchy of the stress response
Summary: Elevated hydrostatic pressure causes changes in gene expression, behaviour and respiration rate in a shallow-water shrimp at different time-scales during and after exposure, highlighting the need to assess more than a single aspect of the overall stress response (OSR) in future physiological studies.
- Functional development of carbon dioxide detection in the maxillary palp of Anopheles gambiae
Summary: Onset of host-seeking behaviour in malaria mosquitoes is correlated with an increased receptor gene expression, and physiological and behavioural sensitivity to CO2.
- Considerations for the use of transcriptomics in identifying the ‘genes that matter’ for environmental adaptation
Summary: The ability of transcriptomics to identify genes that underlie environmental adaptation is explored in the context of recent systems-level experiments that provide new insights into the relationship between gene expression and fitness.
- Divergent physiological responses in laboratory rats and mice raised at high altitude
Summary: Rats and mice that have been raised for a similar period of time under conditions of chronic hypoxia at high altitude display divergent physiological responses.
