Temperature-dependent development and freezing survival of protostrongylid nematodes of Arctic ungulates: implications for transmission

Table 3 Summary of the models (binomial GLM, logit link) fitted to experimental data on the survival of U. pallikuukensis and V. eleguneniensis, including effects of freezing duration (day), temperature (temp), and parasite species (species). Only the top 5 models comprising 90% of the cumulative Akaike weight were considered
