starvation
- Threshold effect in the H2O2 production of skeletal muscle mitochondria during fasting and refeeding
Summary: In ducklings, skeletal muscle mitochondrial ROS release remains low until a threshold level of mitochondrial inactivity is exceeded.
- Increased mitochondrial energy efficiency in skeletal muscle after long-term fasting: its relevance to animal performance
Summary: The optimization of mitochondrial energy metabolism in skeletal muscle should favour the preservation of locomotion and thermoregulation, key physiological performances critical to survival in the final phase of fasting.
- Both thyroid hormone levels and resting metabolic rate decrease in African striped mice when food availability decreases
Summary: Seasonal changes occur in the relationship between thyroid hormone levels and resting metabolic rate in free-living African striped mice: a negative relationship exists in the moist season but not the dry season.
- Stress and food deprivation: linking physiological state to migration success in a teleost fish
Summary: Individual energetic state appears to dictate future life-history strategy whereas an artificial stressor impairs growth and reduces survival regardless of life-history strategy.
- Adaptations to polar life in mammals and birds
Summary: Polar animals are well adapted to the hardships of polar life.
- The implications of reduced metabolic rate in resource-limited corals
Summary: Starved of food and light, corals can reduce their metabolism, lose biomass and maintain skeletogenesis; this strategy can be explained by the dynamics of structural and reserve biomass.
- Discontinuous gas-exchange cycle characteristics are differentially affected by hydration state and energy metabolism in gregarious and solitary desert locusts
Summary: This study shows that haemolymph loss and energy metabolism combine to affect the ability of insects to maintain discontinuous gas exchange cycles under stressful conditions.
- Skeletal muscle phenotype affects fasting-induced mitochondrial oxidative phosphorylation flexibility in cold-acclimated ducklings
Summary: Starvation increases the energy coupling efficiency of muscle mitochondria, which triggers an economical management of fuels and might drive the fatty acid shift from oxidation to storage within the tissue.
