Bringing free-living animals into captivity subjects them to the stress of both capture and captivity, leading to the alteration of normal physiological processes and behaviors through activation of the hypothalamic–pituitary–adrenal axis. In free-living birds, although elevated plasma corticosterone (CORT) is an important adaptation regulating physiological and behavioral responses during the process of capture and captivity stress, little information is currently available on the effects of such stress on plasma metabolite levels. We examined the effects of immediate capture and 24-h captivity on body mass, body condition, plasma CORT, and metabolite levels including glucose (Glu), triglyceride (TG), total cholesterol (TC), uric acid (UA), in breeding Eurasian Tree Sparrows (Passer montanus). CORT and Glu levels were increased significantly by the stress of capture, whereas TC and UA levels decreased. Body mass, body condition declined notably after 24 h in captivity, but CORT, Glu, and UA levels increased. Furthermore, male sparrows had lower TG levels after both capture and captivity than those of females. The relationships between plasma CORT and metabolite levels varied between sexes. Our results revealed that the metabolic status of Eurasian Tree Sparrows could be dramatically altered by capture and captivity. Monitoring the dynamic effects of both capture and captivity on plasma CORT, metabolite levels in a free-living bird contributes to a better understanding of the stress-induced pathways involved in sex-dependent energy mobilization.

捕获和人工饲养对繁殖欧亚麻雀血浆皮质酮和代谢产物水平的影响

将自由活动的动物带入囚禁使它们承受捕获和囚禁的压力,通过激活下丘脑-垂体-肾上腺轴导致正常生理过程和行为的改变。在自由活动的鸟类中,血浆血浆皮质酮(CORT)升高是调节捕获和人工应激过程中生理和行为反应的重要适应手段,但目前尚无有关这种应激对血浆代谢物水平影响的信息。我们在繁殖中检查了立即捕获和24小时人工饲养对体重,身体状况,血浆CORT和代谢物水平(包括葡萄糖(Glu),甘油三酸酯(TG),总胆固醇(TC),尿酸(UA))的影响欧亚树麻雀(Passer montanus)。捕获压力显着提高了CORT和Glu水平,而TC和UA水平则下降了。圈养24小时后,体重,身体状况明显下降,但CORT,Glu和UA水平升高。此外,雄麻雀在捕获和圈养后的TG含量均低于雌性。血浆CORT与代谢物水平之间的关系在男女之间有所不同。我们的结果表明,欧亚树麻雀的代谢状态可能会因捕获和圈养而发生巨大变化。监测捕获和囚禁对血浆CORT的动态影响,在自由生存的鸟类中代谢产物的水平有助于更好地了解与性别相关的能量动员涉及的应激诱导途径。圈养24小时后,身体状况明显下降,但CORT,Glu和UA水平升高。此外,雄麻雀在捕获和圈养后的TG水平均低于雌麻雀。血浆CORT与代谢物水平之间的关系在男女之间有所不同。我们的结果表明,欧亚树麻雀的代谢状态可能会因捕获和圈养而发生巨大变化。监测捕获和囚禁对血浆CORT的动态影响,在自由生存的鸟类中代谢产物的水平有助于更好地了解与性别相关的能量动员涉及的应激诱导途径。圈养24小时后,身体状况明显下降,但CORT,Glu和UA水平升高。此外,雄麻雀在捕获和圈养后的TG水平均低于雌麻雀。血浆CORT与代谢物水平之间的关系在男女之间有所不同。我们的结果表明,欧亚树麻雀的代谢状态可能会因捕获和圈养而发生巨大变化。监测捕获和囚禁对血浆CORT的动态影响,在自由生存的鸟类中代谢产物的水平有助于更好地了解与性别相关的能量动员涉及的应激诱导途径。血浆CORT与代谢物水平之间的关系在男女之间有所不同。我们的结果表明,欧亚树麻雀的代谢状态可能会因捕获和圈养而发生巨大变化。监测捕获和囚禁对血浆CORT的动态影响,在自由生存的鸟类中代谢产物的水平有助于更好地了解与性别相关的能量动员涉及的应激诱导途径。血浆CORT与代谢物水平之间的关系在男女之间有所不同。我们的结果表明,欧亚树麻雀的代谢状态可能会因捕获和圈养而发生巨大变化。监测捕获和囚禁对血浆CORT的动态影响,在自由生存的鸟类中代谢产物的水平有助于更好地了解与性别相关的能量动员涉及的应激诱导途径。
