Results of GLMMs of the occurrence probability of anti-flavivirus and anti-WNV antibodies as functions of sampling period (two classes: September = 0 vs. June = 1), oasis type (two classes: traditional = 0 vs. modern = 1), oasis distance to coast (continuous variable) and dove age (young = 0 vs. adult = 1) as fixed effects and oasis identity as a random factor
