城市环境正在迅速扩张，城市化给野生动物带来了挑战和机遇。挑战包括应对人为干扰，如光、噪音和空气污染，以及天然食物来源的减少。好处是多方面的，包括人类食物来源的可用性，繁殖箱和温暖的温度。因此，根据不同的背景下，城市化可以有积极和消极的影响健身相关的性状。众所周知，早期生活条件可能对健康产生终身影响;然而，对城市环境中的发展知之甚少。我们交叉培育城市和农村雏鸟大山雀（Parus major L.）研究在城市和农村环境中长大如何影响端粒长度（TL）--一种被认为是长寿的生物标志物。我们表明，第一次，在城市环境中长大显着缩短TL，独立于纳塔尔地（即城市或农村）。这意味着城市环境对正在发育的鸟类构成了挑战，可能对寿命产生不可逆转的影响。
Urban environments are expanding rapidly, and with urbanization come both challenges and opportunities for wildlife. Challenges include combating the anthropogenic disturbances such as light, noise and air pollution and lower availability of natural food sources. The benefits are many, including the availability of anthropogenic food sources, breeding boxes and warmer temperatures. Thus, depending on the context, urbanization can have both positive and negative effects on fitness related traits. It is well known that early-life conditions can have lifelong implications on fitness; little is however known about development in urban environments. We reciprocally cross-fostered urban and rural nestling great tits (Parus major L.) to study how growing up in an urban versus rural habitat affected telomere length (TL)-a suggested biomarker of longevity. We show, for the first time, that growing up in an urban environment significantly shortens TL, independently of natal origin (i.e. urban or rural). This implies that the urban environment imposes a challenge to developing birds, with potentially irreversible effects on lifespan.
