    Effects of developmental environment on animal personality in a tropical skink

    Developmental environments play a significant role in sha** animal phenotype, including behavior. Within a species, individuals often differ in behavior in a consistent and repeatable way (i.e., demonstrate ...

    Heritability of climate-relevant traits in a rainforest skink

    There is justified concern about the impact of global warming on the persistence of tropical ectotherms. There is also growing evidence for strong selection on climate-relevant physiological traits. Understand...

    Behavioural responses of an Australian colubrid snake (Dendrelaphis punctulatus) to a novel toxic prey item (the Cane Toad Rhinella marina)

    The invasion of a toxic prey type can differentially affect closely related predator species. In Australia, the invasive Cane Toad (Rhinella marina) kills native anurophagous predators that cannot tolerate the to...

    Chemoreception and mating behaviour of a tropical Australian skink

    In many reptile groups, molecular systematics is currently revealing high levels of cryptic diversity (i.e. genetically distinct lineages that are difficult to distinguish morphologically). One obvious mode fo...

    Ontogenetic shifts in a prey’s chemical defences influence feeding responses of a snake predator

    Foraging theory suggests that predator responses to potential prey should be influenced by prey chemical defences, but the effects of ontogenetic variation in such defences on prey vulnerability to predators r...

    Adaptation or preadaptation: why are keelback snakes (Tropidonophis mairii) less vulnerable to invasive cane toads (Bufo marinus) than are other Australian snakes?

    Biological invasions can expose native predators to novel prey which may be less nutritious or detrimental to predators. The introduction and subsequent spread of cane toads (Bufo marinus) through Australia has k...

    Something different for dinner? Responses of a native Australian predator (the keelback snake) to an invasive prey species (the cane toad)

    Predictions from foraging theory suggest that the probability a native predator will incorporate a novel type of prey (such as an invasive species) into its diet depends upon the potential benefits (e.g., nutr...

    Locomotor performance in an invasive species: cane toads from the invasion front have greater endurance, but not speed, compared to conspecifics from a long-colonised area

    Cane toads (Bufo marinus) are now moving about 5 times faster through tropical Australia than they did a half-century ago, during the early phases of toad invasion. Radio-tracking has revealed higher daily rates ...
