Age‐independent telomere length predicts fitness in two bird Species
Abstract Telomeres are dynamic DNA‐protein structures that form protective caps at the ends of eukaryotic chromosomes. Although initial telomere length is partly genetically determined, subsequent accelerated telomere shortening has been linked to elevated levels of oxidative stress. Recent studies...
