Table 1.

Comparison of support for generalized linear mixed models of binomial counts of exposed seeds on the soil surface (response variable) with field as a random effect and field location (corner or center), seed type (corn or soybean), field type (Cooperative Farming Agreement, DNR-planted, or private), field size in ha (log transformed), and survey date as predictors. Seed type and survey date are not in the same model because soybeans are planted after corn. Field type and Log(field size) are not in the same model because private fields are larger than public fields managed for wildlife.
