Differential allocation in a gift-giving spider: males adjust their reproductive investment in response to female condition

Table 2 Summary of the statistical models used to explain pre-copulatory (Abdominal touches and Latency to pedipalp insertion) and copulatory (Total duration of pedipalp insertions and Total sperm transferred) investment by males exposed to females in POOR and GOOD condition

Predictors	Estimate	SE	t-value	p-value
Abdominal touches
Intercept (POOR females)	6.17	1.26	4.905	< 0.001
GOOD females	8.43	2.79	3.022	0.004
Duration of the mating interaction	0.49	0.22	2.215	0.031
GOOD females × Duration of the mating interaction	− 0.27	0.26	− 1.047	0.300
Latency to pedipalp insertion
Intercept (POOR females)	3.18 (24.15)	0.20	15.715	< 0.001
GOOD females	0.51 (1.67)	0.30	1.719	0.085
Total time of pedipalp insertion
Intercept (POOR females)	0.65	0.25	2.63	< 0.001
GOOD females	2.04	0.46	4.41	< 0.001
Duration of interaction	0.16	0.05	2.98	0.004
GOOD females × Duration of interaction	− 0.19	0.05	− 3.51	< 0.001
Total sperm transferred
Intercept (POOR females)	50,846.11	7262.34	7.00	< 0.001
GOOD females	2889.66	8627.38	0.33	0.739
Total time of pedipalp insertion	4881.56	3669.48	1.33	0.189
GOOD females × Total time of pedipalp insertion	− 2599.45	4033.99	− 0.64	0.522

In the model of Abdominal touches, the total duration of the mating interaction (starting with gift acceptance and finishing with the couple’s separation) was included as continuous predictor. For the model of Latency to pedipalp insertion, we report the estimate in log units and the original units are presented in parentheses. Significant results are highlighted in bold. SE = standard error
