Data on physical performance in Northern Quolls

Description

Data from a study of physical performance and morphology in Northern Quolls, Dasyurus hallucatus. These data were collected to test hypotheses about trade-offs between different types of physical activity. NB all physical measurements are standardised to a mean of 0 and an SD of 1.
