Analysis of evolutionarily stable strategies (ESS) and decade-long field studies indicate that two color morphs of female side-blotched lizards exhibit density- and frequency-dependent strategies. Orange females are r-strategists: they lay large clutches of small progeny that are favored at low density. Conversely, yellow females are K-strategists: they lay small clutches of large progeny that are favored when carrying capacity is exceeded and the population crashes to low density. Interactions… 
SOCIAL CAUSES OF CORRELATIONAL SELECTION AND THE RESOLUTION OF A HERITABLE THROAT COLOR POLYMORPHISM IN A LIZARD
TLDR
Methods and statistical inference for measuring natural selection in small social groups are described and the heritability of color is confirmed, and therefore its genetic basis, by producing progeny from controlled matings.
Adaptive social and maternal induction of antipredator dorsal patterns in a lizard with alternative social strategies.
TLDR
This work illustrates a (previously undescribed) mechanism for females to simultaneously resolve differing correlational selection pressures on different progeny, promoting adaptation to more complex environments.
Lonely hearts or sex in the city? Density-dependent effects in mating systems

TLDR
Considering density-dependent selection may be essential for understanding how populations can persist at all despite sexual conflict, but simple models seem to fail to predict the diversity of observed responses in nature.
Colour Polymorphism and Alternative Breeding Strategies: Effects of Parent’s Colour Morph on Fitness Traits in the Common Wall Lizard
Colour polymorphism (CP) is widespread in animals, but mechanisms underlying morph evolution and maintenance are not completely resolved. In reptiles, CP is often genetically based and associated
An experimental test for alternative reproductive strategies underlying a female‐limited polymorphism
TLDR
The hypothesis that Brown anole lizards (Anolis sagrei) exhibit a genetically based polymorphism in dorsal pattern that is expressed only by females is refuted, as no differences among morphs in the frequency of egg production or in the number, frequency, size or sex ratio of offspring are revealed.
Discrete genetic variation in mate choice and a condition-dependent preference function in the side-blotched lizard: implications for the formation and maintenance of coadapted gene complexes
TLDR
It is found that females of the side blotch lizard did in fact show genetic variation in preference for males but that females also operate a multicondition preference function dependent upon the genotype of the female and her state (number of clutches laid).
Models of Density‐Dependent Genic Selection and a New Rock‐Paper‐Scissors Social System
TLDR
Genic selection coupled to density regulation is widespread and thus fundamental to theories of social system evolution as well as theories of population regulation in diverse animal taxa.
Social Games and Genic Selection Drive Mammalian Mating System Evolution and Speciation
TLDR
The proposed genic mating system theory can explain mating system transitions regardless of resource distribution and provides alternative explanations, such as evolutionary inertia, when resource ecology and mating systems do not match.
The Opportunistic Serpent: Male Garter Snakes Adjust Courtship Tactics to Mating Opportunities
TLDR
Social parasitism in Red-sided garter snakes in Manitoba reveals an unsuspected plasticity and complexity in the behavioural tactics of reproducing male snakes.
MATERNAL ADJUSTMENT OF EGG SIZE ORGANIZES ALTERNATIVE ESCAPE BEHAVIORS, PROMOTING ADAPTIVE PHENOTYPIC INTEGRATION
TLDR
Adaptive maternal effects on escape behaviors within each throat color morph are shown, providing insight into the role of body shape in organizing (and constraining) evolution of integrated reproductive and antipredator strategies.

Mate choice games, context-dependent good genes, and genetic cycles in the side-blotched lizard, Uta stansburiana
TLDR
A game theoretical model predicts that cues from the current social environment should be used by females to choose a mate that maximizes the future reproductive success of progeny, given the social environment of the next generation.

TLDR
Using nuclear microsatellites to estimate the paternity rates of three male lizard strategies previously modeled as a rock-paper-scissors game, yellow-throated sneaker males sire offspring via secretive copulations and often share paternity of offspring within a female's clutch, indicating that sperm competition may be an important component of their strategy.
Density cycles and an offspring quantity and quality game driven by natural selection
TLDR
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.

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
Female choice, conflict between the sexes and the evolution of male alternative reproductive behaviours
TLDR
This paper argues that interactions between the sexes (such as female choice and intersexual conflict) are a common but ignored mechanism that will influence the evolution of male alternative reproductive behaviours, and examines the influence of female choice on the stability and expression of male alternatives.
CONDITION, GENOTYPE‐BY‐ENVIRONMENT INTERACTION, AND CORRELATIONAL SELECTION IN LIZARD LIFE‐HISTORY MORPHS
TLDR
Important interactive effects such as genotype‐by‐environment interaction toward the social environment and morph‐specific trade‐offs as well as the occurrence of correlational selection are revealed.
The evolution of alternative reproductive strategies: fitness differential, heritability, and genetic correlation between the sexes.
TLDR
The fitness results in a system of five alternative mating strategies present in one population of side-blotched lizards (Uta stansburiana) are reviewed and the implications for the evolution and maintenance of reproductive polymorphism in this and other systems are discussed.

TLDR
Analysis of mate choice of females from the selection experiments provides some evidence for correlated divergence in preference as predicted by theory, and could contribute to the correlated pattern of variation in colour pattern and female preference across guppy populations.
