This study unraveled the impacts of accelerated aging pace as a corollary of climate-driven population decline. We found transgenerational accumulation of telomere shortening implying that offspring were already born “old”. We suggest that this process may exacerbate across generations, leading to an aging loop in the population. This model posits that telomere dynamics should represent a molecular biomarker of extirpation, and likely a central cause and promising solution for future biodiversity managing actions.
