Table 7 Results of several analyses of covariance to test the effect of latitude and longitude on various reproductive parameters

From: Geographical location affects size and materials used in the construction of European Pied Flycatcher (Ficedula hypoleuca) nests

Reproductive parameter Latitude Longitude R 2
Nest initiation 2.45 (0.119) 2.41 (0.122) 3.01
Clutch initiation 0.66 (0.417) 8.84 (0.003) 4.88
Nest building 1.63 (0.203) 1.95 (0.164) 0.84
Clutch size 3.28 (0.071) 6.54 (0.011) 2.37
%Hatched 0.48 (0.489) 2.17 (0.142) 0.74
%Fledged 0.50 (0.482) 3.14 (0.078) 1.07
  1. Non-significant interaction between latitude and longitude was removed from the model, which was run again. The parameter in each row was tested individually. Percentage hatchability and fledging were arc sine h transformed prior to analysis. Values are F statistics, with p values in parentheses. Degrees of freedom = 1291 in each model
