Avian models have the potential to elucidate basic cellular and molecular mechanisms
underlying the slow aging rates and exceptional longevity typical of this group of vertebrates …

Oxidative stress (OS) experienced early in life can affect an individual's phenotype.
However, its consequences for the next generation remain largely unexplored. We …

Nest size has been suggested to be a sexually selected signal, allowing individuals to
obtain reliable information about partner quality and thereby optimize paternal investment in …

Oxidative stress can contribute to an acceleration of telomere erosion, leading to cellular
senescence and aging. Increased investment in reproduction is known to accelerate …

Urbanization constitutes one of the major transformations of natural habitats, creating new
areas characterized by multiple potential wildlife stressors. Birds that live in highly …

In vertebrates, developmental conditions can have long-term effects on individual
performance. It is increasingly recognized that oxidative stress could be one physiological …

Oxidative status has been proposed as an important ecological and evolutionary force given
that pro-oxidant metabolites damage molecules, cells and tissues, with fitness …

Measuring oxidative stress has become increasingly valuable in ecological studies,
especially when different markers are measured on the same individual. However, many of …

It is increasingly recognized that alterations of the cellular oxidative status might be an
important cost underlying challenging early life conditions. For example, an increased litter …

Both Ca deficiency and metal exposure may affect physiological and nutritional condition of
breeding females altering their ability to deposit essential resources (eg Ca, antioxidants) …
