摘要: 通过直接观察和胃容物分析对胎生蜥蜴(Lacerta vivipara)的捕食行为和食性进行了研究。结果表明,胎生蜥蜴的捕食过程包括觅食、攻击前行为、攻击行为、猎物处死、吞食、食后清洁共6个主要步骤。在6~10月间,胎生蜥蜴的食谱中以昆虫和蜘蛛最多;不同月份的食物种类和数量不同;食物中以个体长为1~10 mm食物数量频率最高;食物组成与生活环境中的无脊椎动物种类有极显著的相关。雌、雄体的食物生态位重叠度较高,而幼体和成体的食物生态位重叠度较低。

Abstract: With direct observation and stomach dissection, this paper studied the predatorybehavior and meal habit of Lacerta vivipara. The results showed that the predatory behavior of L. vivipara included searching for, before attacking, at tacking, executing, swallowing, and cleaning after eating. During the period fro m June to October,L. vivipara preferred insects and spiders. The kind and quantity of the preys that L. vivipara ate varied from month to month. Among the preys, those of 1-10 mm length were ingested with the highest amount. The natural diet ofL. vivipara was significantly related to the composition of in vertebrates in the environment, and the overlap of food niche was higher between male and female but lower between adult and young L. vivipara.
