Consumption of prey by Walleye.
Description
Consumption of prey by Walleye (Sander vitreus) at different prey densities.
Format
A data frame of 23 observations on the following 2 variables:
- PreyDensity
Density of prey (mg per g per day).
- FoodConsump
Food consumption by predator (mg per cubic meter)
Topic(s)
Nonlinear modeling
Source
