Management of at-risk species requires attention to species-specific resource requirements. In butterflies, lack of information on resource selection in adults limits conservation. We investigated nectar plant use and selection by Fender's blue butterfly (Plebejus [¼ Icaricia] icarioides fenderi), a species endangered by loss of over 99% of prairie habitat in Oregon's Willamette Valley, USA. We observed 156 male and 75 female nectaring bouts by Fender's blue at 3 sites across the range of the species concurrent with weekly surveys of nectar availability. Overall, 53% of nectar uses by males and 20% of uses by females were on nonnative species. Of the 24 plant species used by males and females, 8 species accounted for 86% of uses. Tests of resource selection (Wilkes l) using compositional analysis for these 8 species were significant, indicating that nectar resources were used selectively, rather than in proportion to availability. Females selected native nectar species over non-native species, whereas patterns for males were less clear. This study highlights the importance of differentiating between males and females when examining habitat requirements for endangered species. In addition, understanding how specific non-native species are used by endangered species will help managers decide when they should be removed or conserved. Ó 2015 The Wildlife Society.

Officers serving in specialist tactical response police teams are highly trained personnel who are required to carry heavy loads and perform explosive tasks. The aim of this study was to determine whether performance on a loaded explosive occupational task (urban rush) or distance-based load carriage tasks (2.4 km or 10 km) were indicative of officer success on a specialist selection course (SSC). Eighteen male police officers (mean age = 32.11 ± 5.04 years) participated in the SSC over five consecutive days. Data were categorized into Group 1 (successful applicants, n = 11) and Group 2 (unsuccessful applicants, n = 7). Independent sample t-tests were performed to determine differences between groups, along with point-biserial correlations to investigate associations between anthropometric and event performance data and course completion success. Alpha levels were set at p = 0.05 a priori. Height (p = 0.025), body weight (p = 0.007), and 2.4 km loaded performance (p = 0.013) were significantly different between groups, where being shorter (rpb(16) = −0.526, p < 0.05), lighter (rpb(16) = −0.615, p < 0.01), and faster (rpb(16) = −0.572, p < 0.05) were associated with course success. While a loaded 2.4 km event is associated with success, a ceiling effect for an explosive anaerobic task and a longer 10 km task may exist, whereby increases in performance are not associated with selection success.
