摘要

摘要：对蜥蜴饮食海拔变化的研究经常发现，不同海拔地区的饮食组成会发生变化。在此，我们研究了在墨西哥普埃布拉和韦拉克鲁斯海拔梯度（3–1900米）的各种栖息地中发现的六个种群的可变Sceloporus variabilis的饮食。这六个种群的可变S.variabilis的饮食在目水平上相似，处女膜虫和鞘翅目是最重要的猎物。然而，在科或属水平上的具体分类群在六个种群中各不相同。六个种群的日粮中植物物质的存在各不相同，其中海拔最低的两个种群和海拔最高的种群含有最多的植物物质。

Does the Diet of Sceloporus variabilis Vary Along an Elevational Gradient?

Abstract: Studies of elevational variation in diets in lizards have often found shifts in diet composition among elevations. Herein, we studied the diets of Sceloporus variabilis from six populations found in a variety of habitats along an elevational gradient (3–1900 m) in Puebla and Veracruz, Mexico. Diets of S. variabilis for the six populations were similar at the order level, with hymenopterans and coleopterans being the most important prey items. However, the specific taxa at the family or genus level varied among the six populations. The presence of plant material in diets varied among the six populations, with the two lowest elevation populations and the highest elevation population containing the most of this material.
