How to measure mitochondrial function in birds using red blood cells: a case study in the king penguin and perspectives in ecology and evolution
Mitochondria are the powerhouse of animal cells. They produce through oxidative
phosphorylation more than 90% of the cellular energy (ATP) required for organism's growth, …

Integrating mitochondrial aerobic metabolism into ecology and evolution
Biologists have long appreciated the critical role that energy turnover plays in understanding
variation in performance and fitness among individuals. Whole-organism metabolic studies …

Does oxidative stress shorten telomeres in vivo? A review
S Reichert, A Stier - Biology Letters, 2017 - royalsocietypublishing.org
The length of telomeres, the protective caps of chromosomes, is increasingly used as a
biomarker of individual health state because it has been shown to predict chances of survival in a …

Plastic but repeatable: rapid adjustments of mitochondrial function and density during reproduction in a wild bird species
Most of the energy fluxes supporting animal performance flow through mitochondria. Hence,
inter-individual differences in performance might be rooted in inter-individual variations in …

[HTML][HTML] Increased brood size leads to persistent eroded telomeres
Costs of reproduction can be divided in mandatory costs coming from physiological,
metabolic, and anatomical changes required to sustain reproduction itself, and in investment-…

Starting with a handicap: effects of asynchronous hatching on growth rate, oxidative stress and telomere dynamics in free-living great tits
A trade-off between resource investment into growth rate and body self-maintenance is likely
to occur, but the underlying molecular mediators of such a trade-off remain to be determined…

Oxidative stress and life histories: unresolved issues and current needs
Life‐history theory concerns the trade‐offs that mold the patterns of investment by animals
between reproduction, growth, and survival. It is widely recognized that physiology plays a …
