Erosion of Lizard Diversity by Climate Change and Altered Thermal Niches
Global extinction projections were validated with local extinctions observed from 1975 to 2009 for regional biotas on four other continents, suggesting that lizards have already crossed a threshold for extinctions caused by climate change.
The rock–paper–scissors game and the evolution of alternative male strategies
MANY species exhibit colour polymorphisms associated with alternative male reproductive strategies, including territorial males and 'sneaker males' that behave and look like females1–3. The…
Behavioral Drive versus Behavioral Inertia in Evolution: A Null Model Approach
A null model is developed that quantifies the impact of regulatory behaviors on body temperature and on performance of ectotherms and supports the alternative view that behavior has diverse—and sometimes conflicting—effects on the directions and rates at which other traits evolve.

Natural and sexual selection on physiological and behavioral traits that leads to the evolution of steroid regulation in the context of alternative male strategies are discussed.
The effects of morphology and perch diameter on sprint performance of Anolis lizards
Variation in leg length among Anolis might represent an evolutionary trade-off between maximizing sprint speed and maximizing stability on thin perches.
Density cycles and an offspring quantity and quality game driven by natural selection
The first example of a genetic r versus K selection game that promotes stable population cycles in lizards is reported, and intrinsic causes of frequency- and density-dependent selection promotes an evolutionary game with two-generation oscillations.
Correlational selection and the evolution of genomic architecture
It is argued that frequency-dependent biotic interactions that have ‘Red Queen dynamics’ (eg, host-parasite interactions, predator-prey relationships or intraspecific arms races) often fuel chronic correlational selection, which is strong enough to maintain adaptive genetic correlations of the kind the authors describe.
THE EVOLUTION OF MATERNAL INVESTMENT IN LIZARDS: AN EXPERIMENTAL AND COMPARATIVE ANALYSIS OF EGG SIZE AND ITS EFFECTS ON OFFSPRING PERFORMANCE

I used comparative and experimental analysis of egg size in a Sceloporus lizard to examine a fundamental tenet of life‐history theory: the presumed trade‐offs among offspring number, offspring size,…
Role of Gene Interactions in Hybrid Speciation: Evidence from Ancient and Experimental Hybrids
The genomic composition of three experimentally synthesized hybrid lineages indicated that selection to a large extent governs hybrid species formation, and interactions between coadapted parental species' genes constrain the genomic compositions of hybrid species.
Allometric Engineering: A Causal Analysis of Natural Selection on Offspring Size
The results experimentally validate premises underlying theories of optimal egg size: fecundity selection favoring the production of large clutches of small eggs was balanced by survival selection favoring large offspring, but large hatchlings did not always have the highest survival, contrary to most theoretical expectations.
