  1. Session = trapping sessions (five levels, May is the reference), Open water = three levels: low, medium and high water coverage in the area (high is the reference), Human density = human population density in the area (human/km2). Random effect = identity of the study site. σ2 = the variance attributable to random effect. sd = standard deviation of σ2. The number of observations is 65.
