Table 2.

Results of two logistic regression models (using Firth’s bias reduction method; brglm package in R⁶⁵) assessing whether treatment (clustered or isolated), female age (in days since the moult to maturity), and the number of males who arrived at their web over the course of the field experiment affected two measures of L. hesperus female choosiness (copulation and pre-copulatory cannibalism) in mating trials.

Response variable	Predictor variable	Estimate	SE	Z	P
Copulation (yes/no)
	density treatment	3.49	1.79	2.01	0.044
	days since moult	0.08	0.07	1.10	0.272
	number of males	0.09	0.13	0.71	0.481
Pre-copulatory cannibalism (yes/no)
	density treatment	−2.05	1.44	−1.42	0.155
	days since moult	−0.03	0.07	−0.42	0.674
	number of males	−0.002	0.11	−0.02	0.987
