Age and heat stress as determinants of telomere length in a long-lived fish, the Siberian Sturgeon [PDF]

open access: yes, 2016
Telomeres shorten at each cell division due to the end-replication problem but also in response to oxidative stress. Consequently, telomeres shorten with age in many endotherms, and this shortening is accelerated under stressful environmental conditions.
