摘要(Abstract):
[目的]评价秋季迁徙林鹬内脏器官及骨骼肌的变化趋势。[方法]选择上海长江河口滨海滩涂区域的林鹬作为样本,分析其秋季在上海中转停歇期间内脏器官及骨骼肌的重量差异,并比较2002~2004年的环志数据,分析其内脏器官及骨骼肌的变化趋势。[结果]林鹬中转停歇期间样本平均体重为(44.337 2±6.191 7)g。增重的最大因素是脂肪,最大可达到平均体重的26%;其次是胸肌部分,变化幅度超过50%;腿肌、剩余骨骼、心、肺、肝、砂囊、肠等器官湿重均有一定幅度的变化,脑、肺、砂囊和肾重量保持稳定。[结论]林鹬中转停歇期间体重明显增加,腿肌、心、肠、肝和骨骼肌其余部分均随体重呈增重趋势,脑、肺、砂囊和肾的重量无变化。
