Australian lizards are a diverse group distributed across the continent and inhabiting a wide
range of environments. Together, they exhibit a remarkable diversity of reproductive …

The squamates occur in a variety of climates from tropical to Arctic regions. Being
poikilotherms, snakes and lizards in temperate regions, and high elevation tropical …

The effects of external conditions on embryonic development have been repeatedly
examined in oviparous reptile species, but the effect of gestation conditions on offspring …

Age and size at maturity are pivotal life-history traits through their effects on other key traits,
such as annual and lifetime fecundity. We used skeletochronology to investigate the …

Summary 1 Understanding individual and population responses to climate change is
emerging as an important challenge. Because many phenotypic traits are sensitive to …

Sex determination systems are exceptionally diverse and have undergone multiple and
independent evolutionary transitions among species, particularly reptiles. However, the …

Two primary dichotomies within vertebrate life histories involve reproductive mode (oviparity
versus viviparity) and sex determination (genotypic sex determination versus environmental …

Fundamental to life-history theory is the assumed inverse proportionality between the
number of offspring and the resource allocation per offspring. Lizards have been model …

Lizards of the viviparous genus Phymaturus inhabit regions in which a significant proportion
of the year is unsuitable for growth and reproduction. All Phymaturus studied have shown …

Life-history theory seeks to explain patterns of variation between species or populations of
the same species. Studies of squamates in general, and lizards in particular, have assumed …
