Hinderer_CMR_data_Ranaluteiventris.csv

These data were collected as part of a study of the relationship between body condition, as measured from length and mass of an animal, body composition, as measured by the mass of different tissues within an animal, and growth in amphibians. There were two main questions of this study: 1) which of some common body condition indices were most effective at describing the amount of fat or lean mass of a several amphibians and 2) whether body condition was related to the potential for growth in one amphibian species.The QMR data is output from quantitative magnetic resonance scans of three species of amphibians (<i>Rana luteiventris, Pseudacris sierra, *and *Ambystoma macrodactylum</i>) to determine body composition, as represented by amounts of fat and lean mass in an individual at the time of scanning. These outputs were then compared to traditional condition indices developed from length and mass measurements. The CMR data is capture-mark-recapture information from a population of individually marked <i>Rana luteiventris</i>, which covered multiple years and was used to study the effects of body condition on individual growth.Description: VariablesSite: Site of animal capture.
