Survival summary

This file summarises the survival of each nest (reproductive output of a single female) over winter in each environment. This summary comes from the life history data, and results from summing the total number of pupae from each nest assigned to each environment, and the resultant number of moths emerging as adults. We have removed all nests that were not represented in each environment, and all nests that had zero survival in both treatments. The nest identifications correspond to the life history data set
