Table 1 Excluded and selected environmental predictor variables for the environmental niche model

From: Evaluating the risk for Usutu virus circulation in Europe: comparison of environmental niche models and epidemiological models

Abbreviation Variables
Excluded—monthly minima and maxima are not suitable to estimate daily fluctuations
 BIO2 Mean diurnal range (mean of monthly (max temp − min temp))
 BIO3 Isothermality (BIO2/BIO7) × 100
Excluded—summer and winter precipitation are important to distinguish for mosquitoes and disease transmission dynamics
 BIO12 Annual precipitation
Excluded—wettest/driest time of the year can be in different seasons across Europe
 BIO8 Mean temperature of wettest quarter
 BIO9 Mean temperature of driest quarter
 BIO13 Precipitation of wettest month
 BIO14 Precipitation of driest month
 BIO16 Precipitation of wettest quarter
 BIO17 Precipitation of driest quarter
Excluded by Jackknife
 BIO4 Temperature seasonality (standard deviation × 100)
 BIO5 Maximum temperature of warmest month
 BIO7 Temperature annual range (BIO5–BIO6)
 BIO10 Mean temperature of warmest quarter
