- A radical shift in perspective: mitochondria as regulators of reactive oxygen species
Summary: Mitochondria are often considered to be a source of harmful reactive oxygen species. Here, we explain how they may behave as regulators of hydrogen peroxide, an important ROS in cellular function.
- The oxidative debt of fasting: evidence for short- to medium-term costs of advanced fasting in adult king penguins
Summary: Fasting induces a transitory exposure to oxidative stress, and effort to recover in body mass after an advanced fasting period may be a neglected carryover cost of fasting in king penguins.
- Current versus future reproduction and longevity: a re-evaluation of predictions and mechanisms
Summary: This paper critically reviews the effects and physiological mechanisms that reproduction could have on bioenergetic capacity to better understand how a reproductive event could affect future reproduction and/or survival.
- Dietary flavonoids advance timing of moult but do not affect redox status of juvenile blackbirds (Turdus merula)
Summary: Dietary flavonoids, despite their potential antioxidant activity, do not affect redox status in blackbirds; however, flavonoids do promote the development of melanin-rich feathers.
- Rapid proteomic responses to a near-lethal heat stress in the salt marsh mussel Geukensia demissa
Summary: After exposure to an acute and near-lethal heat stress, gill from the mussel Geukensia demissa responds immediately with a coordinated time course of changes in protein abundance.
- Stress, nutrition and parental care in a teleost fish: exploring mechanisms with supplemental feeding and cortisol manipulation
Summary: Stress and nutritional condition are key modulators of physiological condition and reproductive success in a parental teleost fish.
- Mitochondrial physiology and reactive oxygen species production are altered by hypoxia acclimation in killifish (Fundulus heteroclitus)
Summary: Hypoxia acclimation reduces mitochondrial release of reactive oxygen species, without affecting mitochondrial respiration, in estuarine killifish.
- Temperature experienced during incubation affects antioxidant capacity but not oxidative damage in hatchling red-eared slider turtles (Trachemys scripta elegans)
Summary: The post-hatch redox status of turtles is influenced by incubation temperature but not temperature fluctuations. Exposure to warmer temperatures for longer durations has negative consequences for hatchling antioxidant capacity.
