Experimental evolution of specialization by a microsporidian parasite

Table 1 Analysis of (A) infectivity and (B) (log-transformed) number of spores in infected individuals for the different test combinations.

		(A) Infectivity		(B) Number of spores in infected individuals
	df	χ²	P	SS (× 10³)	F	P
Test combination	3	28.60	< 0.001	194	1.26	0.288
Evolution regime [Test combination]	6	11.90	0.064	326	1.05	0.390
Replicate [Test, Evolution regime]	25	22.35	0.615	1262	0.98	0.497
Error	531			57438

The analysis compares the four types of tests: specialized parasites on their own host, specialized parasites on mismatched hosts, parasites evolved on mixtures of hosts and parasites evolved on alternating hosts. 'Evolution regime' refers to the isofemale line (or combination of lines) the parasites evolved on.
