- 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.
- Chum salmon migrating upriver adjust to environmental temperatures through metabolic compensation
Highlighted Article: Thermal accommodation in salmon migrating upriver is achieved via thermal metabolic compensation.
- Aerobic capacities and swimming performance of polar cod (Boreogadus saida) under ocean acidification and warming conditions
Summary: Polar cod is a key species in the Arctic ecosystem; its swimming capacity decreases under future water conditions, likely reducing its survival.
- Digestive and locomotor capacity show opposing responses to changing food availability in an ambush predatory fish
Summary: Southern catfish downregulate digestive function and metabolic rate during food deprivation, but regain digestive capacity during refeeding, potentially at the cost of decreased swimming performance.
- Elevated temperature and acclimation time affect metabolic performance in the heavily exploited Nile perch of Lake Victoria
Summary: Upper thermal tolerance limits and metabolic traits of a heavily exploited, tropical freshwater fish (the Nile perch) have high thermal plasticity without incurring major energetic costs.
- Turbulence induces metabolically costly behaviors and inhibits food capture in oyster larvae, causing net energy loss
Editors' Choice: Late-stage oyster larvae are unable to gain energy in strong turbulence, even at very high food concentrations, because turbulence induces metabolically costly behaviors while inhibiting food capture.
- Physiological responses to short-term thermal stress in mayfly (Neocloeon triangulifer) larvae in relation to upper thermal limits
Highlighted Article: Respirometry and gene expression experiments suggest that oxygen limitation may not dictate the chronic upper thermal limits of the mayfly Neocloeon triangulifer.
- Economic thermoregulatory response explains mismatch between thermal physiology and behaviour in newts
Summary: Digesting newts prefer body temperatures that are optimal for aerobic scope not in absolute terms but relative to the minimum oxygen consumption.
- Oxygen dependence of upper thermal limits in fishes
Summary: A novel metric (PCTmax) is presented for assessing the oxygen sensitivity of upper thermal limits in water-breathing ectotherms based on measurements of critical thermal maxima in marine fishes under hypoxia.
- Intraspecific variation in physiological performance of a benthic elasmobranch challenged by ocean acidification and warming
Summary: Juvenile little skates from neighboring locations, developmentally acclimatized to varying levels of ocean acidification and warming, exhibit substantial differences in escape and aerobic performance.
