Oxidative stress results from an imbalance between the production of reactive oxygen
species and the antioxidants defences, in favour of the former. In recent years, the …

Biologists have long appreciated the critical role that energy turnover plays in understanding
variation in performance and fitness among individuals. Whole-organism metabolic studies …

Oxidative stress may be of profound biological relevance. In this Commentary, I discuss
some key issues faced by the emerging field of oxidative stress ecology, and seek to provide …

Physiologists often assume that mitochondria are the main producers of reactive oxygen
species (ROS) in cells. Consequently, in biomedicine, mitochondria are considered as …

The concept of a pace‐of‐life syndrome describes inter‐and intraspecific variation in several
life‐history traits along a slow‐to‐fast pace‐of‐life continuum, with long lifespans, low …

Evolutionary biology and biomedicine have seen a surge of recent interest in the possibility
that telomeres play a role in life-history trade-offs and ageing. Here, I evaluate alternative …

Reproduction, a basic property of biological life, entails costs for an organism, ultimately
detectable as reduction in survival prospects. Telomeres are an excellent candidate …

Senescence—the decline in age‐specific contribution to fitness with increasing age—has
been widely investigated in evolutionary ecology. A tremendous amount of detailed …

Human-induced climate change is occurring rapidly. Ectothermic organisms are particularly
vulnerable to these temperature changes due to their reliance on environmental …

As average lifespan of humans increases in western countries, cardiac diseases become
the first cause of death. Aging is among the most important risk factors that increase …
