资源简介：
This file corresponds to the field population growth analyses. Values of r were calculated for Daphnia pulicaria in Lake Mendota (ME) and Lake Monona (MO) for years before (pre) and after (post) invasion by Bythotrephes. The start date is the first day of sampling each year. For example, a sample conducted on February 3 would have a start date = 34. The start density refers to the estimated density of Daphnia on the start date. Sampling was performed by the North Temperate Lakes LTER. All data are available at: https://lter.limnology.wisc.edu/.
