Mortality affects adaptive allocation to growth and reproduction: field evidence from a guild of body snatchers

Table 1 Statistics from the generalized linear model^a using observed individual growth (mm³) as the response variable.

Explanatory variable or statistic	df	Χ²	P
"species"^b	9	68.68	<0.0001
Initial size	1	60.45	<0.0001
"species" × initial size	9	18.87	0.026
Estuary	2	3.79	0.15
habitat [estuary]	1	9.55	0.002
site [estuary, habitat]	13	193.68	<0.0001
growing time [estuary]	2	84.42	<0.0001

goodness of fit (deviance)	1648	6422.59	<0.0001

^aThe model used a log-link, a Poisson error distribution, and an overdispersion parameter of 4.53. Brackets indicate nested effects.
^b"Species" indicates species of trematode parasitic castrator and male or female uninfected snail hosts.
