Incremental 95% MCP accumulation curve showing the number of locations required to more accurately estimate the dry season (Apr-Sep) home ranges for black rhino in Hluhluwe-iMfolozi Park (HiP), South Africa.

Historical sequence of home range estimates for black rhino <i>Diceros bicornis minor</i> in Hluhluwe-iMfolozi Park, South Africa.

<p>Included for comparison are the four home range estimates from this study where different analysis techniques were used (i.e., Hitchin’s [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0150571#pone.0150571.ref045" target="_blank">45</a>–<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0150571#pone.0150571.ref046" target="_blank">46</a>] visual approximation technique, 95% MCP’s, 90% and 95% kernels). Standard error is included for home range estimates where possible. Note that the unshaded (white) bars represents average range sizes for female rhino, whereas the shaded (light grey) bar represents male averages. The darker shaded bar (dark grey) represents the home range average for males and females combined, as Reid et al. [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0150571#pone.0150571.ref008" target="_blank">8</a>] did not report estimates for the different sexes.</p

Post-release mortality in black rhinoceros (<i>Diceros bicornis</i>) after (A) reintroduction and (B) restocking.

<p>Cohort size and habitat quality (estimated carrying capacity <0.1, 0.1–0.2 or >0.2 rhino per km²) explained reintroduction mortality while age class explained deaths after restocking. Age classes conform to Hitchins' A (calf) to F (adult) aging scheme <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030664#pone.0030664-Beech1" target="_blank">[31]</a>. Numbers of rhino (i.e., n) in each category are indicated above each bar. nd = no data. The dash line across each indicates mean mortality rate for all reintroduction (A) and restocking (B) events.</p

Results summary of the 29 candidate models for reintroduction mortality risk among 89 cohorts and 414 reintroduced black rhino.

<p>Models are in descending order from most to least supported based on Akaike second-order Information Criteria (AIC_c). Leading models from previous analyses without interaction terms <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030664#pone.0030664-HoeghGuldberg1" target="_blank">[<i>9]</i></a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030664#pone.0030664-Frair1" target="_blank">[23<i> </i>]</a> are italicized. The model without fixed effects is indicated in bold type. A ‘*’ indicates an interaction term in the regression between two variables and, by implication, predictors in interactions were also present additively in models (e.g., a*b refers to model including a+b+a*b as fixed effects).</p
