The effects of incubation thermal environments on size, locomotor performance and early growth of hatchling soft-shelled turtles, Pelodiscus sinensis
Identifying sources of variation in reproductive and life-history traits among five populations of a Chinese lizard (Takydromus septentrionalis, Lacertidae)
TLDR
The extensive geographical variation in reproductive and life-history traits that occurs within T. septentrionalis is exhibited even in long-term captives, suggesting that proximate factors that vary among localities are less important determinants of life- history variation than are intrinsic (presumably genetic) influences.
Incubation temperature affects hatchling growth but not sexual phenotype in the Chinese soft-shelled turtle, Pelodiscus sinensis (Trionychidae)
TLDR
The data support previous work that P. sinensis does not have temperature-dependent sex determination, and add evidence for the prediction that turtles within the Trionychidae have genotypic sex determination exclusively.
Does body-volume constrain reproductive output in lizards?
TLDR
Surgical manipulations show that the amount of space available to hold eggs within a female's abdomen influences her total reproductive allocation, enabling her to flexibly modify her reproductive output as she grows larger.
Phenotypic plasticity in reproductive traits induced by food availability in a lacertid lizard, Takydromus septentrionalis

TLDR
Egg size and phenotypic traits of hatchlings (body size, morphology and locomotor performance) in T. septentrionalis did not vary significantly from first to second clutches nor between the two treatments, which support optimal egg size (offspring) theory.
Determinants of incubation period: do reptilian embryos hatch after a fixed total number of heart beats?
TLDR
Non-invasive monitoring of embryo heart beat rates in one turtle species and two lizards show that the total number of heart beats during embryogenesis is relatively constant over a wide range of warm incubation conditions, and predicts incubation period in non-avian reptiles as well as in birds.
Why do the eggs of lizards (Bassiana duperreyi: Scincidae) hatch sooner if incubated at fluctuating rather than constant temperatures?
TLDR
An exponential relationship between temperature and heart rate is found, which means that embryonic cardiac output was increased more by adiel increase in temperature than it was decreased by a diel fall in temperature, leading to 7% more daily heartbeats at 22 ±7° Cthan at 22 °C.
Do operational sex ratios influence sex allocation in viviparous lizards with temperature‐dependent sex determination?
TLDR
Although maternal body temperature during pregnancy was influenced by OSR, the variation in temperature was not great enough to affect litter sex ratios or any other phenotypic traits of the offspring.
Patterns of developmental plasticity in response to incubation temperature in reptiles.
TLDR
This work systematically review research into thermal developmental plasticity across reptiles, structured around the key papers and findings that have shaped the field over the past 50 years, and introduces a large database, the 'Reptile Development Database', consisting of 9,773 trait means across 300 studies examining thermal developmental Plasticity.
