Performance and Signaling in the Green Anole Lizard

Developmental regulation of hemoglobin synthesis in the green anole lizard Anolis carolinensis.

Tetrapod vertebrates possess multiple α- and β-like globin genes that are ontogenetically regulated, such that functionally distinct hemoglobin (Hb) isoforms are synthesized during different stages of development. The α- and β-like globin genes of amphibians, birds and mammals are differentially expressed during embryonic development and postnatal life, but little is known about the development...

Developmental regulation of hemoglobin synthesis in the green anole lizard <i>Anolis carolinensis</i>

Tail loss and narrow surfaces decrease locomotor stability in the arboreal green anole lizard (Anolis carolinensis).

Tails play an important role in dynamic stabilization during falling and jumping in lizards. Yet tail autotomy (the voluntary loss of an appendage) is a common mechanism used for predator evasion in these animals. How tail autotomy has an impact on locomotor performance and stability remains poorly understood. The goal of this study was to determine how tail loss affects running kinematics and ...

Androgen metabolism in the brain of the green anole lizard (Anolis carolinensis).

Activities of the steroid metabolizing enzymes aromatase and 5 alpha-reductase have been documented in species ranging from fish to humans, yet relatively little work has been done in this area in reptiles. In the green anole lizard, Anolis carolinensis, steroid hormones are critical to the display of both masculine and feminine sexual behaviors. For example, dihydrotestosterone and testosteron...

Climate-mediated adaptation after mainland colonization of an ancestrally subtropical island lizard, Anolis carolinensis.

Climate-mediated evolution plays an integral role in species migration and range expansion. Gaining a clearer understanding of how climate affects demographic history and adaptation provides fundamental insight into the generation of intra- and interspecific diversity. In this study, we used the natural colonization of the green anole (Anolis carolinensis) from the island of Cuba to mainland No...
