The evolution of sexual size dimorphism in reptiles
TLDR
To address the major evolutionary hypotheses for SSD, this chapter focuses on recent comparative studies that examine the relationships between SSD and various ecological and evolutionary correlates across multiple populations and species. Expand
A COMPARATIVE TEST OF ADAPTIVE HYPOTHESES FOR SEXUAL SIZE DIMORPHISM IN LIZARDS
TLDR
The comparative data at present provide only weak support for these hypotheses as general explanations for SSD in lizards, and are consistent with the criticism that categorical variables may obscure much of the actual variation in intrasexual selection intensity needed to explain patterns in SSD. Expand
Locomotor capacity and foraging behaviour of kalahari lacertid lizards
TLDR
Theoretical models of foraging behaviour should recognize that ectotherms have limited endurance, that there can be a trade-off between speed and endurance, and that pre-feeding can reduce some aspects of locomotor capacity. Expand
Testosterone Regulates Sexually Dimorphic Coloration in the Eastern Fence Lizard, Sceloporus undulatus
TLDR
It is shown that sexual divergence in ventral coloration is temporally correlated withSexual divergence in plasma testosterone in free-living juvenile males and females, supporting the hypothesis that sexual dichromatism is regulated at least in part by testosterone. Expand
Effect of water constraint on growth rate, activity and body temperature of yearling common lizard (Lacerta vivipara)
TLDR
It is observed that a low water supply induced a lower growth rate and lower activity level, suggesting that growth limitation is correlated with adaptive responses to avoid dehydration and there is population variability in phenotypic plasticity with respect to water availability in the habitat. Expand
Effect of testosterone on immunocompetence, parasite load, and metabolism in the common wall lizard (Podarcis muralis)
TLDR
The effects of testosterone on one component of the immune system, parasite load, and metabolic rate in the common wall lizard, Podarcis muralis (Laurenti, 1768), are studied. Expand
Hormones, performance and fitness: Natural history and endocrine experiments on a lizard (Sceloporus undulatus).
TLDR
A strong correlation between the level of plasma corticosterone and the number of offspring sired is found, indicating that for males, both the number and the size of their mates increase with body size, and the results illustrate ecological and evolutionary significance of individual variation in endocrine traits. Expand
Testosterone Inhibits Growth in Juvenile Male Eastern Fence Lizards (Sceloporus undulatus): Implications for Energy Allocation and Sexual Size Dimorphism
TLDR
Surgical castration and subsequent administration of exogenous T was used to alter the physiological and behavioral phenotypes of field‐active males to suggest that male growth may be constrained by energetic costs of activity and implicate T as a physiological regulator of this potential trade‐off. Expand
Thermal Physiology, Phenology, and Distribution of Tree Frogs
TLDR
It is suggested that some aspects of the community organization of hylids, such as breeding phenology and the depauperate faunas of high latitudes, are constrained at least in part by thermal physiology. Expand
