  1. The degrees of freedom for the F-test of "Marker Type" were 3 for the numerator and 37, and 33, for the denominator of swarm size and total couples, respectively (four swarms with size estimates had no complete measurement of total couples).
  2. aF denotes that the standard F-test for fixed effects and Z denotes Wald-Z tests for the covariance parameter estimates
