Abstract

Increased exposure to artificial light at night (ALAN) has changed the scenario for natural day length over time. The impact of ALAN has been studied on reproduction, sleep, metabolism, and behavior in many species. ALAN's impact on birds' immune response is still sparsely studied. We studied the cell-mediated immunity, hematology, and reproductive phenology in redheaded bunting under short days (SD, 8L:16D), long days (LD) (LAN -, 13L:11D), and LD with ALAN (LAN +, 13L:11DLAN) illuminated with ~ 2 lx of night light. Corticosterone levels, testicular volume, heterophil count, and H/L ratio increased significantly in the LAN + group. Cell-mediated immune response (phytohemagglutinin-L challenge), total leucocyte, and lymphocyte count were significantly suppressed in the LAN + as well as LAN - group relative to the SD group of birds. ALAN treatment did not affect the total erythrocyte count, hemoglobin level, surface body temperature, and hematocrit level. Basophil, eosinophil, and monocyte count, as well as body mass and blood glucose levels, did not show any significant difference among any groups. These results suggest that ALAN exposure compromised the adaptive immune system, increased stress levels, and exaggerated the reproductive response in migratory passerine finches.

鸟类的困境:红发猎鸟对环境光污染的细胞介导免疫受损。
随着时间的推移,夜间暴露于人造光(ALAN)的增加已经改变了自然白昼长度的情况。ALAN对许多物种的繁殖、睡眠、新陈代谢和行为的影响已被研究。ALAN对鸟类免疫反应的影响研究仍然很少。我们研究了短日照(SD, 8L:16D)、长日照(LD) (LAN -, 13L:11D)和ALAN +光照(LAN +, 13L:11DLAN)下红头发狩猎的细胞免疫、血液学和生殖物候。LAN +组皮质酮水平、睾丸体积、嗜异性粒细胞计数和H/L比值显著升高。与SD组相比,LAN +组和LAN -组的细胞介导的免疫反应(植物血凝素- l攻击)、白细胞总数和淋巴细胞计数明显受到抑制。ALAN治疗不影响红细胞总数、血红蛋白水平、体表体温和红细胞压积水平。嗜碱性粒细胞、嗜酸性粒细胞和单核细胞计数,以及体重和血糖水平,在任何组之间都没有显示出任何显著差异。这些结果表明,ALAN暴露损害了迁徙雀鸟的适应性免疫系统,增加了应激水平,并夸大了生殖反应。
