In ryanraaum/qmdata: Datasets for Quantitative Methods for Biological Anthropology Course

These data are from a study evaluating the effects of predation risk on growth and reproduction in a hermaphroditic freshwater snail.

snails

A data frame (tibble) with 711 rows and 11 variables:

family: factor: identifier for full-sibling families
predator: factor: P=predator, NP=no predator
mate: factor: M=mate, NM=no mate
treatment: factor: all combinations of mate and predator
mass: number: mass in mg
thickness: number: shell thickness in mm
length: number: shell length in mm
age: number: age in days at time of mass, thickness, and length measurements
fr_age: number: age in days at time of first reproduction
fr_mass: number: mass in mg at time of first reproduction
fr_length: number: length in mm at time of first reproduction
