Substantial intraspecific variation in energy budgets: biology or artefact?

Data on the growth and reproduction of Trinidadian guppies (Poecilia reticulata) from sixteen different populations, reared under experimental conditions of either high or low food availability. These data were used to fit dynamic energy budgets models for each of the populations. For twelve populations, there are three sets of observations per individual, recorded at each successive parturition event. For four of the populations, data were recorded at each parturition event over the full lifespan of each individual. 

Methods
These are data on the growth and reproduction of individually housed Trinidadian guppies, reared under experimental conditions of either low or high food.  Data are collated from three sets of experiments that followed the same general protocol, although the experimental food treatments differed between experiments. Please refer to the manuscript “Substantial intraspecific variation in energy budgets: biology or artefact?", published in Functional Ecology, for details on the experimental procedures.
