Title Individual soil mite data
Downloaded 2 times
Description Indiv is a data frame stored in "Individual soil mite data.Rdata" which contains the following columns relevant to the sampling experiment. *trt* has levels that represent the food treatment: T1 (constant), T2 (famine), T3 (declining), T4 (fluctuating) *pop.ID* is a unique identifier for each of 2 replicate populations per treatment. *date* is the date when a sampling event began *stage* is the life stage of the individual at the beginning of the 24 hour sampling period. *ind.ID* is a unique identifier of an individual observed for a sampling period. *s24* is 1 if the individual was alive after 24 hours, 0 if it was dead, or NA if it was lost. *t24* indicates transiton to either the same stage as the beginning of the sampling period (initial stage) the next, or in between stages (quiescent). *f24* is the number of eggs laid in the 24 hour sampling period. *l0* is the body length at the beginning of the sampling period (mm). *l24* is the body length at the end of the sampling period (mm). *density* is the approximate value of body lenghths summed over the population on the date of sampling (see apendix S2 from publication) (mm). *supply* is food given divided by density on the date of sampling (mg/mm). *food* is the amount of food given to the population on that date (mg). *density.s* is the density scaled to have mean 0 and variance 1. *supply.s* is the supply scaled to have mean 0 and variance 1. *l0.s* is body length scaled to have mean 0 and variance 1. *day* is the number of days since the start of the experiment.

Title Egg size from sampling
Downloaded 1 time
Description eggdat is a data frame stored in "Egg size from sampling.Rdata" contianing measurments of individual eggs from sampled females. *egg.ID* is a unique identifier for an egg. *pop.ID*, *date*, *trt*, *s24*, *f24*, *l0*, *l0.s*, *density*, *density.s*, *supply*, and *supply.s* are the same as in the individual data in another file. *fem.ID* is the same as indiv.ID above for the mother of the eggs. *esize* is the size of the sampled egg (mm).

Title Population Counts with Predictors
Downloaded 2 times
Description Pop.counts is a data frame stored in "Population Counts with Predictors.Rdata" containing stage specific counts from both sampling and counting populations. *date*, *trt*, *pop.ID*, *density*, *supply*, *food*, *density.s*, *supply.s*, and *day* are the same as in the individual data in another file. *pop.type* is the type of the population counting or sampling (see appendix S1 for details). *eggtot*, *larvaetot*, *prottot*, and *trittot* are are *4 times* the number of soil mites in a given stage (egg, larvae, protonymph, tritoonymph) counted in a quarter of the tube where the population was living (see appendix S1 for details). *maletot* and *femaletot* are the number of adult mites counted in the entire population (see appendix S1 for details).
