Gibson2016_AmNat_Mortality

Mortality data for 2013, 2014, and 2015 artificial inoculations. Each row gives identifying information and infection data for an experimental replicate. Columns: 1) “year” gives the year of the artificial inoculation experiment (2013-2015); 2) “site” gives the site from which experimental juveniles were collected (13 sites); 3) “treatment” gives experimental treatment. Control replicates did not receive parasites and are marked as 0. Infections in control replicates were acquired prior to collection of juvenile snails from the field and reflect early-life exposure to parasites. Exposed replicates received field-collected parasites and are marked as 1; 4) “source” applies to the 2014 artificial inoculation experiment in which two distinct sources of parasites were used for inoculations. Replicates exposed to source 1 (southern end of lake) are marked as 1, replicates exposed to source 2 (northeastern site, JMS) are marked as 2, and control replicates are marked as 0; 5) “replicate” indicates the experimental replicate, nested with year*site; 5) “total” gives the total number of female snails in the experimental replicate at initiation of the experiment; 6) “present” gives the number of female snails that were present (i.e. alive) at the time of dissection of the experimental replicate; and 7) “absent” is “total” minus “present” – the number of female snails missing (i.e. presumed dead) at the time of dissection of the replicate.
