在浙江发现并记述了4种白化鸟类:2020年5月1日和12月18日,在杭州西湖景区花港公园水域发现1例白化斑嘴鸭Anas zonorhyncha;2020年10月15日,在台州玉环漩门湾国家湿地公园三期芦苇水塘内发现1例白化小䴙䴘Tachybaptus ruficollis;2021年3... 在浙江发现并记述了4种白化鸟类:2020年5月1日和12月18日,在杭州西湖景区花港公园水域发现1例白化斑嘴鸭Anas zonorhyncha;2020年10月15日,在台州玉环漩门湾国家湿地公园三期芦苇水塘内发现1例白化小䴙䴘Tachybaptus ruficollis;2021年3月13日,在衢州龙游湖镇东金村林地内发现1例白化珠颈斑鸠Streptopelia chinensis;2021年3月23日,在衢州龙游湖镇东金村水田里发现1例白化白鹡鸰Motacilla alba。根据上述鸟类的羽毛、虹膜、喙、跗跖等的颜色,判定斑嘴鸭、小䴙䴘和珠颈斑鸠为局部白化个体,判定白鹡鸰为完全白化个体。目前,鸟类白化机制尚未明确,可能与基因、环境及生理代谢有关,需进一步深入研究。本文结果可为动物白化研究提供案例,也可为《浙江野生动物志》的编撰提供基础资料。 展开更多

The hexoses glucose, galactose and fructose serve as important dietary energy sources in animals and glucose plays a central role in energy homeostasis within eucaryotic cells. As relatively little is known about patterns of hexose transporters expression in birds gastrointestinal tract, the aim of the study was to examine glucose transporters 2 (GLUT-2) and glucose transporters 5 (GLUT-5) expression in stomach and duodenal epithelium of two different species--broilers (Gallus gallus domesticus) and ostriches (Struthio camelus var. domesticus) chicken. Materials from the two parts of gastrointestinal tract were collected from six 7-day-old female broilers and six 7-day-old female ostriches. Specimens were fixed with 10% formalin, embedded into paraffin, cut into 7 lain thick slices, followed by immunohistochemical staining with polyclonal primary antibodies rabbit anti-GLUT-2 and rabbit anti-GLUT-5; the staining was carried out according to the manufacturers guidelines (IHC kit, Abcam, UK). The investigation showed that the staining for both antibodies was more intensive in the epithelial cells of stomach and duodenum of the 7-day-old broilers. In duodenal epithelium, goblet cells and brush border membranes were stained in both species, however the signal was stronger for GLUT-5 than GLUT-2. Staining for GLUT-2 and GLUT-5 occurred in different parts of gastrointestinal tract of 7-day-old ostriches, but was weaker compared to 7-day-old broilers, which showed that the gastrointestinal tract of 7-day-old female broilers was more developed for transportation ofhexoses than 7-day-old female ostriches. 展开更多
