This data set consists of counts of anuran larvae as a function of pond type, pond perimeter, and presence of water scorpions (Ranatra sp.).
A data frame with 24 observations on the following 6 variables.
pond type, denotes the location of ponds in either bog or upland environment
number of anuran larvae in minnow traps
number of trap nights (i.e., number of traps x days of trapping) in each pond
pond perimeter in meters
number of water scorpions trapped in minnow traps
natural log of perimeter
Mazerolle (2006) uses this data set to illustrate model selection for Poisson regression with low overdispersion.
