Mean time spent in stereotypic Flipping behavior.

<p>The mean number of seconds per 600 s observation period that mice spent in Flipping behavior is given for the two replicates of RAN (blue), MK (green), and DOC (red) experimental populations.</p

Mean litter size.

<p>The mean number of pups born in first and second litters is given for the two replicates of RAN (blue), MK (green), and DOC (red) experimental populations.</p

Litter survival to weaning at 20 days.

<p>The mean survival of litters (with each litter scored as survival = 1 if more than 50% of pups survive, and survival = 0 otherwise) is given for the two replicates of RAN (blue), MK (green), and DOC (red) experimental populations.</p

Delay between pairing and litter birth.

<p>The mean time (d) between pairing and the birth of a litter for those pairs that produced at least one litter is given for the two replicates of RAN (blue), MK (green), and DOC (red) experimental populations. Note that the y-axis starts at 20 d, a few days shorter than the typical gestation period.</p

Probability that a pair will breed.

<p>The proportion of pairs that produced at least one litter conceived within 70 days is given for the two replicates of RAN (blue), MK (green), and DOC (red) experimental populations.</p

Mean time spent in stereotypic Flipping behavior.

<p>The mean number of seconds per 600 s observation period that mice spent in Gnawing behavior is given for the two replicates of RAN (blue), MK (green), and DOC (red) experimental populations.</p

Weaning Mass.

<p>The mean mass (g) of pups weaned for those pairs that produced at least one litter is given for the two replicates of RAN (blue), MK (green), and DOC (red) experimental populations.</p

Size of experimental populations of <i>Peromyscus</i><i>leucopus</i> mice across generations.

<p>Each population started with 40 mice in 20 pairs, and thereafter the population size is the number of mice weaned from up to 20 pairs established each generation. For all figures, the mean values at each generation for RAN replicates are shown in blue, MK replicates shown in green, and DOC replicates shown in red. Lines are labeled as to replicate to the right of each line.</p

Accumulated inbreeding under three breeding protocols.

<p>The mean inbreeding coefficient (F) at each generation accumulated in closed populations of 20 pairs per generation is given for the two replicates of RAN (blue), MK (green), and DOC (red) experimental populations.</p
