“…For instance, based on the principle that biochemical and physiological systems operating at high temperatures have a high catalytic capacity, the "hotter is better" hypothesis predicts a positive relationship between maximal organismal performance and optimal temperatures [71]. This relationship holds when considering interspecific [61,72] or intraspecific comparisons [73,74].…”

Caudal autotomy is a dramatic adaptation used by many lizard species to evade predators. Most studies to date indicate that caudal autotomy impairs lizard locomotor performance. Surprisingly, some species bearing the longest tails show negligible impacts of caudal autotomy on sprint speed. Part of this variation has been attributed to lineage effects. For the first time, we model the effects of caudal autotomy on the locomotor performance of a gymnophthalmid lizard, Micrablepharus atticolus, characterized by a long and bright blue tail. To improve model accuracy, we incorporated the effects of several covariates. We found that body temperature, pregnancy, mass, collection site, and the length of the regenerated portion of the tail were the most important predictors of locomotor performance in Micrablepharus atticolus. However, sprint speed was unaffected by tail loss. Apparently, the long tail of M. atticolus is more useful when using undulation amidst the leaf litter and not when using quadrupedal locomotion on a flat surface. Our findings highlight the intricate relationships among physiological, morphological, and behavioral traits. We suggest that future studies about the impacts of caudal autotomy among long-tailed lizards should consider the role of different microhabitats/substrates on locomotor performance, using laboratory conditions that closely mimic their natural environments.

“…Within regions, species that utilize sunny open habitats are more heat tolerant than relatives found in cool, shaded environments (Gunderson et al 2018). Accompanying this physiological variation are diverse behavioral strategies: Whereas some species allow their body temperature to passively fluctuate with the environment (thermoconformers), others actively bask or seek shade to maintain a precise body temperature (thermoregulators) (Logan et al 2015, Muñoz & Losos 2018, Méndez-Galeano et al 2020) (Figure 2e). Anoles exhibit a range of regional diversity patterns (Figure 2c).…”

Following decades of intensive study, Anolis lizards have emerged as a biological model system. We review how new research on anoles has advanced our understanding of ecology and evolution, challenging long-standing paradigms and opening new areas of inquiry. Recent anole research reveals how changes in behavior can restructure ecological communities and can both stimulate and stymie evolution, sometimes simultaneously. Likewise, investigation of anoles as spatial or phylogenetic evolutionary experiments has documented evolutionary repeatability across spatiotemporal scales, while also illuminating its limits. Current research places anoles as a promising model for Anthropocene biology, with recent work illustrating how species respond as humans reconfigure natural habitats, alter the climate, and create novel environments and communities through urbanization and species introduction. Combined with ongoing methodological developments in genomics, phylogenetics, and ecology, the growing foundational knowledge of Anolis positions them as a powerful model system in ecology and evolution for years to come.
