Summary of field data collected during Daphnia epidemics

All data are seasonal averages (September - November). Lakes were sampled weekly or biweekly (every other week) during this period. Key to columns: "Lake" = lake sampled; "Refuge" = depth of the hypolimnetic refuge (meters); "D.size" = average size of adult female D. dentifera (the index of fish predation; mm); "Chaob" = density of Chaoborus punctipennis (m-2); "Chaob2" = ln(Chaob); "D.dens" = density of Daphnia dentifera (cm-2); "C.dens" = density of Ceriodaphnia sp. (cm-2); "P.dens" = density of Daphnia pulicaria (cm-2); "D.freq" = frequency of Daphnia dentifera; "C.freq" = frequency of Ceriodaphnia sp.; "P.freq" = frequency of Daphnia pulicaria; "Amb.freq" = frequency of Daphnia ambigua; "Par.freq" = frequency of Daphnia parvula; "Dia.freq" = frequency of Diaphanosoma sp.; "Bos.freq" = frequency of Bosmina sp.; "Sca.freq" = frequency of Scaholeberis sp.; "Chy.freq" = frequency of Chydorus sp.; "Alo.freq" = frequency of Alona sp.; "O.freq" = frequency of all rare cladocerans pooled together; "Simpsons" = inverse Simpsons diversity index; "M.prev" = infection prevalence of Metschnikowia bicuspidata in Daphnia dentifera; "M.dens" = density of Daphnia dentifera infected with Metschnikowia bicuspidata (cm-2).
