Effects of rodent abundance on ticks and Borrelia: results from an experimental and observational study in an island system

Table 1 The estimated effect of island size on NIP_t+1, DON_t+1, and DIN_t+1 in relation to island type (small control islands vs large islands)

Response variable^a	Explanatory variable^b	Estimate (standard error)	Z-value	P-value
NIP_t+1	Intercept	− 1.33 (0.22)	− 6.02	< 0.001
NIP_t+1	Large island	− 0.63 (0.31)	− 1.99	0.046*
DIN_t+1	Intercept	1.71 (1.18)	1.44	0.19
DIN_t+1	Large island	1.25 (1.67)	0.75	0.48
DON_t+1	Intercept	8.10 (5.45)	1.49	0.18
DON_t+1	Large island	14.8 (7.70)	1.92	0.09

*Statistically significant
^aNIP_t+1 (nymph infection prevalence in following year [2020]) was estimated using generalized linear models (GLMs). DON_t+1 (density of nymphs in following year [2020]) and DIN_t+1 (density of infected nymphs the following year [2020]) were estimated using linear models (LM)
^bSmall control islands are included in the intercepts
