- An early life hypoxia event has a long-term impact on protein digestion and growth in juvenile European sea bass
Summary: The growth reduction in juvenile sea bass as a consequence of an early life hypoxia event is due to a specific change in the efficiency of protein digestive functions.
- Avian torpor or alternative thermoregulatory strategies for overwintering?
Highlighted Article: Low BMR, communal roosting and insulation of the roost nest enable white-browed babblers to survive winter without resorting to torpor, suggesting heterothermia is not a common thermoregulatory strategy for passerine birds.
- Correlations of metabolic rate and body acceleration in three species of coastal sharks under contrasting temperature regimes
Summary: Calibrations between metabolic rate, body acceleration and temperature in three coastal sharks offer a tool to estimate field metabolic rates in these species.
- Do respiratory limitations affect metabolism of insect larvae before moulting? An empirical test at the individual level
Summary: Respiratory limitations for metabolism appear in the penultimate larval instar but not in the last instar in growing butterfly larvae, supporting oxygen-dependent moult induction in larva-to-larva moults.
- Energy and lipid metabolism during direct and diapause development in a pierid butterfly
Summary: Diapause termination in Pieris napi requires chilling, energy is stored for post-diapause purposes and the diapause lipidome is distinct but lacks dynamics during diapause development.
- Shoaling reduces metabolic rate in a gregarious coral reef fish species
Highlighted Article: Group living reduces metabolic rate in a shoaling damselfish species, while isolation reduces body condition. Social isolation due to environmental disturbance may therefore have physiological consequences for gregarious species.
- Aerobic scope increases throughout an ecologically relevant temperature range in coho salmon
Summary: Coho salmon do not conform to existing predictions about the temperature dependence of aerobic scope in Pacific salmon.
- Oxygen and energy availability interact to determine flight performance in the Glanville fritillary butterfly
Summary: Low oxygen and circulating trehalose availability constrain flight metabolism in the Glanville fritillary butterfly.
- Streamwise vortices destabilize swimming bluegill sunfish (Lepomis macrochirus)
Summary: Fish exposed to streamwise vorticity increase energy consumption on average by 6%, likely due to spilling events and subsequent recovery, which were much more frequent under vorticity.
