我们在Ava和Lutz两个地点评估了蜥蜴Anolis Limifrons的存活率。从1976-1979年和在Lutz遗址的两个时期。1971-1976 vs 1976-1979，巴拿马巴罗科罗拉多岛。成年雌性和雄性的存活没有区别，青少年和成年的存活也没有区别。相比之下，1971-1976年期间Lutz站点的存活率显著高于1976-1979年间，AVA的存活率显著高于1976-1979年间Lutz站点的存活率。年平均存活率分别为0.042、0.013、0.055。这些比率与这个和其他小的大陆Anolis人每年的人口流动报告是一致的。生存的时间和空间变化与栖息地、季节、观察年份或鸟类捕食者的数量和丰度无关。从生活史进化的角度，对比了大陆Anolis和西印度群岛物种的生存模式。
We evaluated survival of the lizard, Anolis limifrons at two sites, AVA and Lutz. from 1976-1979 and during two periods at Lutz site. 1971-1976 vs 1976-1979, at Barro Colorado Island, Panama. Survival of adult females and males did not differ nor did survival of juveniles and adults. In contrast, survival was significantly higher at Lutz site during 1971-1976 than during 1976-1979 and survival was significantly higher at AVA than at Lutz site during 1976-1979. On an annual basis, mean survival rates were 0.042, 0.013, 0.055 for Lutz 1971-1976, Lutz 1976-1979, and AVA 1976-1979, respectively. These rates are in accord with reports of annual population turnover for this and other small mainland Anolis. Temporal and spatial variation in survival was not associated with habitat, season, year of observation, or numbers and abundances of avian predators. Survival patterns of mainland Anolis are contrasted with those of West Indian species in terms of life history evolution.
