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.

毛里求斯的圆岛拥有一个稀有的特有蜥蜴物种社区。他们的环境被引进的山羊和兔子（现在已经被消灭了）清除了大部分植被。Durrell野生动物保护信托基金会，哥伦比亚野生动物基金会和政府的国家公园和保护服务之间的合作伙伴关系允许恢复栖息地，并恢复爬行动物为主的脊椎动物群落（科尔等人。爬行动物物种占据了景观经历植物群落恢复，但鲜为人知的是无脊椎动物猎物的可用性。蜥蜴和壁虎已被证明对环境变化具有显著的适应力，尽管有些物种已从岛上的爬行动物群落中灭绝。很可能爬行动物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生态位。其中一种，特尔费尔石龙子，是一个多面手，消费范围广泛的不同分类群。其他物种可能有更窄的生态位轴和更专业化。
