Allometry and selection in a novel predator-prey system: Australian snakes and the invading cane toad
Article Abstract:
An organism's body size profoundly influences a multitude of biologically significant traits, ranging from metabolic rates to habitat use, modes of locomotion and life history characteristics. Across snake species, mean adult body size does not affect vulnerability and smaller predators were more vulnerable, because the intraspecific rate of decrease in relative head size of snakes was steeper than the rate of increase in toxicity of toads.

Costs of reproduction in a lizard species: a comparison of observational and experimental data
Article Abstract:
Research on Tasmanian snow skink lizard (Niveoscincus microlepidotus) show that lizards with naturally occurring, large reproductive investments survived better than lizards with large reproductive investments brought on by experiments using follicle stimulating hormones. This study highlights the differences between field and experimental research methods.

A radiotelemetric study of movements and thermal biology of insular Chinese pit-vipers (Gloydius shedaoensis, Viperidae)
Article Abstract:
A collaborative study between Australian and Chinese scientists, to clarify the ecology of the Shedao pit-vipers is cited. The aim of the study is to describe the spatial and thermal ecology of these snakes using radiotelemetry.
