Table 1.

Cichlid fecundities and egg diameters differed significantly between habitats and lakes

Effect	Number of eggs			Egg diameter
	F	df	P	F	df	P
Habitat	38.61	2, 123	< 0.001	15.711	2, 115	< 0.001
Lake	16.06	2, 123	< 0.001	24.243	2, 115	< 0.001
Lake × habitat	1.55	4, 119	0.193	16.437	4, 115	< 0.001
Body mass	120.8	1, 119	< 0.001	6.450	1, 115	0.012

The relationships between egg diameter and habitat varied between lakes (analyses of covariance).
