摘要

摘要 由于气候变化和人类活动,南极长尾雉的分布范围、栖息地和种群数量正在发生变化。为了评估它们的健康状况,我们在南极洲南奥克尼岛劳里岛繁殖期间采集了雄性和雌性南乔治亚岛鲣鸟(Phalacrocorax georgianus)的血液和生化指标。对白细胞概况、嗜异性细胞/淋巴细胞比率、血细胞比容以及葡萄糖、总蛋白、胆固醇和甘油三酯的浓度进行了测量。所测指标均未显示临床病理或疾病迹象。总体而言,所测参数与之前报道的其他鸬鹚物种的参数一致。雄性鸬鹚的蛋白质和胆固醇浓度较高,这表明雌雄鸬鹚在繁殖期间的营养状况存在差异。这项研究是首次报道南极洲南乔治亚岛鸬鹚的血液参数,可能有助于将来对不同物种和不同地理区域的血液参数进行荟萃分析比较。

Physiological parameters of South Georgia Shag (Phalacrocorax georgianus) during breeding in South Orkney Island, Antarctica

Abstract

Due to climate change and human activities, Antarctic shag populations are experiencing shifts in their distribution range, habitat, and population size. To assess their health, we collected hematological and biochemical of male and female South Georgia shags (Phalacrocorax georgianus) during breeding on Laurie Island, South Orkney Island, Antarctica. Leukocyte profile, heterophil/lymphocyte ratio, hematocrit, and concentrations of glucose, total proteins, cholesterol, and triglycerides were measured. None of the measured metrics showed signs of clinical pathology or disease. Overall, the parameters measured were consistent with those previously reported for other cormorant species. Males had higher protein and cholesterol concentrations, indicating differences in nutritional status between the sexes during reproduction. This study is the first report on blood parameters of South Georgia shags in Antarctica and may be useful for future meta-analyzes comparing blood parameters of different species and geographic areas.

期刊介绍: Polar Biology publishes Original Papers, Reviews, and Short Notes and is the focal point for biologists working in polar regions. It is also of interest to scientists working in biology in general, ecology and physiology, as well as in oceanography and climatology related to polar life. Polar Biology presents results of studies in plants, animals, and micro-organisms of marine, limnic and terrestrial habitats in polar and subpolar regions of both hemispheres.
