Kay et al RSPB-2013-2374 worker survivorship experiment, untreated ants

For survival assays, we measured responses of solitary and social ant groupings to treatment with M. anisopliae (strain KVL02-73 collected at this site (Hughes et al. 2004)). After the 18-day diet manipulation, we created 1-ant (solitary ants) or 5-ant (worker groups) sets from each colony. In Jan 2012, we assigned 5 solitary ants and 1 worker group per colony to a control treatment (not challenged with Metarhizium).
