Impact of inbreeding coefficients of male and female breeders on the reproductive parameters of yellow steppe lemmings (Eolagurus luteus) in the Moscow Zoo captive colony, 2017–2021

Covariate	β ± SE	95% CI	P-value	Effect
Total number of litters (mean: 7.4 ± 0.9)
FxF	−4.96 ± 1.75	−8.47 to −1.45	0.006	Negative
FxM	−4.53 ± 2.53	−9.6 to 0.54	0.08	No effect
FxF*FxM	34.75 ± 12.73	8.86 to 60.66	0.008	Positive
Total number of born pups (mean: 22.8 ± 3.08)
FxF	−4.74 ± 1.89	−8.55 to −0.93	0.015	Weak negative
FxM	−4.6 ± 3.1	−10.8 to 1.59	0.1	No effect
FxF*FxM	38.2 ± 15.07	7.55 to 68.86	0.015	Weak positive
Total number of survived pups (mean: 19.9 ± 2.8)
FxF	−5.2 ± 1.82	−8.87 to −1.54	0.005	Negative
FxM	−3.73 ± 3.12	−9.97 to 2.51	0.24	No effect
FxF*FxM	35.21 ± 16.58	1.48 to 68.95	0.04	Weak positive

Averaged coefficient estimates (regression coefficient β with SE) and confidence intervals (CI) are taken from the best-approximating models (Table 1) containing parameters: F_xF, female inbreeding coefficient; F_xM, male inbreeding coefficient.
