衰老、社交和性。随着年龄的增长，他们的身体功能和生存前景都会下降。尽管社会环境被认为是重要的，但为什么有些人在生命中退化得更慢、更晚，这是一个我们无法充分回答的关键问题。使用最近建立的衰老分子生物标记物，该项目旨在通过实验在一只野鸟中调查，当个人缺乏社会支持或面临性竞争时，与年龄相关的衰退是否会更快。预期结果是对延缓衰老和延长寿命的关键决定因素的洞察。潜在的好处包括更好地理解健康老龄化的驱动因素，以及提高预测人口持久性和确定保护优先事项的能力。

Senescence, sociality and sex. As individuals age, their body functions and survival prospects decline. Why some individuals deteriorate slower and later in life, is a critical question we cannot adequately answer, although the social environment has been suggested to be important. Using a recently established molecular biomarker of aging, this project aims to experimentally investigate in a wild bird if age-related decline is faster when individuals lack social support or face sexual competition. Expected outcomes are insights into key determinants of delayed aging and longer lifespan. Potential benefits include improved understanding of drivers of healthy aging, and improved ability to predict population persistence and identify conservation priorities.
