Round Island, Mauritius, hosts a community of rare endemic lizard species. Their environment was cleared of most vegetation by introduced goats and rabbits (now eliminated). A partnership between the Durrell Wildlife Conservation Trust, Mauritian Wildlife Foundation and the Government's National Parks and Conservation Service has permitted the restoration of habitat and with it the recovery of the reptile-dominated vertebrate community (Cole et al. 2018). The reptile species occupy a landscape going through plant community recovery, but little is known about availability of the invertebrate prey. The skinks and geckos have proved to be remarkably resilient to environmental change, although some species were extirpated from the island's reptile community. It is likely the reptiles originally adapted to different niches, including trophic niches that allowed them to avoid direct competition. One species, the Telfair's skink, is a generalist, consuming a wide range of different taxonomic groups. Other species may have narrower niche axes and be more specialised.

毛里求斯的朗德岛拥有稀有的特有蜥蜴物种群落。他们的环境中的大部分植被被引入的山羊和兔子清除（现已消灭）。达雷尔野生动物保护信托基金、毛里求斯野生动物基金会和政府国家公园和保护局之间的合作伙伴关系已经允许恢复栖息地，并恢复以爬行动物为主的脊椎动物群落（Cole等人，2018）。爬行动物物种占据了正在经历植物群落恢复的景观，但人们对无脊椎动物猎物的可用性知之甚少。尽管一些物种已从岛上的爬行动物群落中灭绝，但石龙子和壁虎已被证明对环境变化具有显着的适应能力。爬行动物很可能最初适应了不同的生态位，包括使它们能够避免直接竞争的营养位。其中一个物种是特尔菲尔石龙子，它是一种多面手，捕食各种不同的分类群。其他物种可能具有更窄的生态位轴并且更加专业化。
