Evolutionary biology: Adaptive developmental plasticity in snakes
The morphology of organisms is generally well matched to their environment, presumably because expression of their genes is tailored either at the population or the individual level to suit localExpand

Sex Differences in Body Size and Ectoparasite Load in the Ball Python, Python regius
Abstract Sexual dimorphism in body size, body condition (body mass relative to body size), and relative head size was investigated on 1250 field-caught Python regius (Togo, western Africa). SexualExpand

Fat Is Sexy for Females but Not Males: The Influence of Body Reserves on Reproduction in Snakes (Vipera aspis)
Reproduction is energetically expensive for both sexes, but the magnitude of expenditure and its relationship to reproductive success differ fundamentally between males and females. Males allocateExpand

Clutch Size manipulation, hatching success and offspring phenotype in the ball python (Python regius)
In a diverse array of avian and mammalian species, experimental manipulations of clutch size have tested the hypothesis that natural selection should adjust numbers of neonates produced so as toExpand

The role of adaptive plasticity in a major evolutionary transition: early aquatic experience affects locomotor performance of terrestrial snakes
1. Many phylogenetic lineages of animals have undergone major habitat transitions, stimulating dramatic phenotypic changes as adaptations to the novel environment. Although most such traits clearlyExpand

The origin of evolutionary innovations: locomotor consequences of tail shape in aquatic snakes
Summary 1Phylogenetic shifts in habitat use often impose strong selective forces on locomotor systems; for example, the transition from terrestrial to aquatic existence has stimulated the evolutionExpand

Do ‘Quiet’ Places Make Animals Placid? Island vs. Mainland Tiger Snakes
Most animals that possess potent venom display a wide variety of warning messages to discourage predators. Tiger snakes are large and highly venomous elapids that exhibit these anti-predatorExpand

Aquatic locomotion and behaviour in two disjunct populations of Western Australian tiger snakes, Notechis ater occidentalis
Adaptive phenotypic plasticity can be viewed as an evolutionary strategy that enables organisms to match their phenotypes to local conditions. I studied two neighbouring populations of amphibiousExpand

Tail loss, body condition and swimming performances in tiger snakes, Notechis ater occidentalis.
In limbless tetrapods such as snakes, propulsive forces are generated by lateral undulations of the body and of the tail. In a large population of tiger snakes from Western Australia, tail loss wasExpand
