The biology of the invasive Polistes dominulus and the native P. fuscatus was compared at a field site in Rochester, Michigan over a two-year period. Colonies nesting semi-naturally in plywood nestboxes were studied using videography, extensive surveys, and colony-specific marking of gynes.Both single-and multiple-foundress colonies of P. dominulus were significantly more productive than comparable colonies of P. fuscatus. The disparity in productivity was significantly more pronounced in single-foundress colonies than in multiple-foundress colonies. P. dominulus had significantly shorter larval and pupal development times than P. fuscatus, which allowed P. dominulus to produce its first workers about a week earlier than P. fuscatus. P. dominulus had a number of additional advantages over P. fuscatus that contributed to its productivity including (1) significantly less parasitism by Strepsiptera, (2) significantly greater probability of renesting after predation by raccoons, (3) significantly lower usurpation pressures, and (4) possibly longer foraging days . The recovery of colony-marked foundresses indicated that gynes of P. dominulus suffered significantly greater mortality than gynes of P. fuscatus during winter diapause and that foundresses of both species were equally, strongly philopatric.P. dominulus is likely replacing P. fuscatus in many areas of southeastern Michigan via indirect or exploitative competition. The two species may be competing for nest sites.
Post-secondary institutions have experienced increased enrollment of student servicemembers and veterans (SSM/V), thus prompting renewed interest in the academic and acculturation needs of SSM/V. Despite the breadth of psychological literature surrounding military and college student populations, there is a gap in knowledge concerning the psychological needs of SSM/V. The primary aim of this study was to explore predictors of attitudes toward psychological helpseeking among SSM/V. In the spring of 2017, SSM/V (n = 103), including 26 females and 77 males, completed self-report questionnaires. Results from the study demonstrated that selfstigma, public-stigma, and gender were significantly correlated with attitudes toward psychological help-seeking. A multiple regression analysis revealed that self-stigma and gender significantly predicted attitudes toward psychological help-seeking. Consistent with previous studies, self-stigma fully mediated the significant relationship between public-stigma and attitudes toward psychological help-seeking. Ultimately, this study highlights the process in which external events adopt internal psychological significance and furthers the discourse surrounding the specific psychological needs of SSM/V.
We explored predictors of attitudes toward psychological help seeking among 103 student service members and veterans (SSM/V). Results showed that self‐stigma, public stigma, and gender significantly predicted attitudes toward psychological help seeking. A test of mediation revealed that self‐stigma fully mediated the relationship between public stigma and attitudes toward psychological help seeking. Implications for college counseling professionals who serve SSM/V are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
