Dietary supply with polyunsaturated fatty acids and resulting maternal effects influence host – parasite interactions

Table 2 Results of statistical analysis of the cumulative number of offspring using a generalized linear model

	Cumulative number of host offspring
(1) direct	df	deviance	residual df	residual deviance	p
subset control “food”	5	494.38	98	181.37	< 0.001
subset infected “food”	5	1035.1	128	812.2	< 0.001

subset control “food”	5	685.94	76	131.35	< 0.001
subset infected “food”	5	481.41	104	482.33	< 0.001

Error distribution = quasi-Poisson, link function = log. (1) D. magna raised under different food regimes (direct supply). (2) D. magna raised under the same food regime (S. obliquus), but mothers raised under different food regimes (maternal effects).
