Avian scavengers living in anthropized landscapes and dense populations have chronic stress and accelerated cell aging
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...
Vitamin E supplementation—but not induced oxidative stress—influences telomere dynamics during early development in wild passerines
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...
Urban blackbirds have shorter telomeres
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...
Physiological mechanisms of adaptive developmental plasticity in Rana temporaria island populations
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...
