Relation between recruitment rate and adult sex ratio.

<p>There is a statistically significant negative relationship between 3-year average recruitment rate <i>Rec</i> and 3-year average sex ratio <i>SR</i> (<i>Rec</i> = −0.23*<i>SR</i>+0.74) for brown bears in the Central (black circles) and Western populations (empty squares).</p

Probability of extinction for the Western population under the sex ratio scenario.

<p>For a given number of released females, releasing more than 2 males increases the probability of extinction by biasing the population adult sex ratio toward males.</p

Probability of extinction for the Western population under the inbreeding scenario.

<p>Releasing several females drastically reduces the probability of extinction.</p

Relation between maternity rate and adult sex ratio.

<p>There is a statistically significant negative relationship between 3-year average maternity rate <i>Mx</i> and 3-year average sex ratio <i>SR</i> (<i>Mx</i> = −0.26*<i>SR</i>+0.95) for brown bears in the Central (black circles) and Western populations (empty squares).</p
