Generalized linear model (GLM) with potential effects on CsTLV1 and CsTLV2 infection.

Model	Predictor variable	Estimate (slope)	Standard Error	p-value
A. Full model:
CsTLV1 Infection~ Latitude + Size + Sex (AIC = 339.98; df = 551)	Latitude	2.54	0.64	6.64e−05***
	Size	−1.00	0.25	9.47e−05***
	Sex	−0.31	0.35	0.37
CsTLV2 Infection1 ~ Latitude + Size + Sex (AIC = 340.89; df = 551)	Latitude	2.68	0.66	4.77e−05***
	Size	−1.12	0.26	1.12e−05***
	Sex	−0.30	0.35	0.39
B. Reduced model:
CsTLV1 Infection ~ Latitude (AIC = 352.24; df = 554)	Latitude	2.33	0.54	1.43e−05***
CsTLV1 Infection ~Size (AIC = 382.85; df = 553)	Size	−1.13	0.24	2.24e−06***
CsTLV1 Infection ~Sex (AIC = 404.68; df = 553)	Sex	−0.13	0.31	0.67
CsTLV2 Infection ~ Latitude (AIC = 357.72; df = 554)	Latitude	2.38	0.54	9.78e−06***
CsTLV2 Infection ~Size (AIC = 385.34; df = 553)	Size	−1.25	0.24	1.42e−07***
CsTLV2 Infection ~Sex (AIC = 412.8; df = 553)	Sex	−0.08	0.30	0.78

The model has the lowest Akaike’s information criterion (AIC) of all combinations of predictor variables (see as full and reduced interactions).
