Analysis of telomeres, markers of ageing, shows that the process of deterioration occurs unevenly in different parts of the body. The ageing of organisms is due to the loss of function of some of...

A study led by the Doñana Biological Estation (CSIC) has compared the health of two populations of griffon vultures (Gyps fulvus) from two populations of the Iberian Peninsula. The research team...

Telomere length is a marker of cellular senescence that relates to different components of individual fitness. Oxidative stress is often claimed as a main proximate factor contributing to telomere...

Urbanization, one of the most extreme human-induced environmental changes, represents a major challenge for many organisms. Anthropogenic habitats can have opposing effects on different fitness...

Adaptive plasticity is essential for many species to cope with environmental heterogeneity. In particular, developmental plasticity allows organisms with complex life cycles to adaptively adjust...
