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

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

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

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
