Elevated Testosterone Is Required for Male Sexual Behaviour and Dynamic Colour Change in Veiled Chameleons Open
Introduction: Sex-specific genotype and early organization can influence the expression of sexually dimorphic traits in vertebrates. We tested these hypotheses in male-typical behaviour and rapid change to bright colouration in the veiled …

Complex ontogeny of sexual size dimorphism in a female‐larger gecko: Implications of determinate growth for lizard body size and life‐history evolution Open
Ectothermic vertebrates such as reptiles were assumed to be indeterminate growers, which means that there is no terminal point in time or size for growth in their lifetime. In recent years, evidence for the determinate nature of growth in …

Pivotal temperature is not for everyone: Evidence for temperature‐dependent sex determination in three gecko species Open
The prevalence of environmental sex determination (ESD) in squamate reptiles is often overestimated in the literature. This is surprising because we have reliable data demonstrating ESD in only a few species. The documentation of ESD in th…

Catch-up growth and overweight adults in the offspring of young gecko mothers resembling low birth weight infants Open
Endothermic and ectothermic amniotes differ in the timing of reproductive onset, with reptiles initiating reproduction before reaching final body size. Long-term consequences of maternal effect for early reptile offspring are poorly explor…

Development of male-larger sexual size dimorphism in a lizard: IGF1 peak long after sexual maturity overlaps with pronounced growth in males Open
Squamate reptiles have been considered to be indeterminate growers for a long time. However, recent studies demonstrate that bone prolongation is stopped in many lizards by the closure of bone growth plates. This shift in the paradigm of l…

Sex-specific growth arrest in a lizard Open
(1) In contrast to mammals and birds, reptiles have been considered as indeterminate growers, whose growth reflects differential allocation of resources to growth versus other energetically demanding processes such as reproduction. (2) We …

Individual and age-related variation of cellular brain composition in a squamate reptile Open
Within-species variation in the number of neurons, other brain cells and their allocation to different brain parts is poorly studied. Here, we assess these numbers in a squamate reptile, the Madagascar ground gecko ( Paroedura picta ). We …

Not all cells are equal: effects of temperature and sex on the size of different cell types in the Madagascar ground gecko <i>Paroedura picta</i> Open
Cell size plays a role in evolutionary and phenotypically plastic changes in body size. To examine this role, we measured the sizes of seven cell types of geckos (Paroedura picta) reared at three constant temperatures (24, 27, and 30 °C). …

Ovarian control of growth and sexual size dimorphism in a male-larger gecko Open
Sexual size dimorphism (SSD) reflects sex-specific solutions to the allocation of energy among growth, reproduction and survival; however, the proximate mechanisms behind these solutions are still poorly known even in vertebrates. In squam…
